No, Trump, Ice Isn’t Growing at Poles, and Yes, We Are Boiling the Earth
Since Trump is not good with reading books and the like, it may be helpful to reply to his falsehoods with graphs.

The Associated Press did a useful  fact check  of Trump’s bizarre assertions on climate change in the interview with his friend Piers Morgan.
Since Trump is not good with reading books and the like, it may be helpful to reply to his falsehoods with graphs.
   
   TRUMP: “There is a cooling, and there’s a heating. I mean, look, it used to not be climate change, it used to be global warming.
   That wasn’t working too well because it was getting too cold all over the place.” – ITV interview.

Actually, no. The average earth surface temperature has been  going up steadily  and indeed faster than most climate scientists predicted.

That is an average surface temperature increase. You have to keep in mind that it includes the oceans, which are cold, and the declining ice-covered parts of the world. So an increase of a degree Centigrade is much more alarming than it sounds. In any particular place, like Phoenix, AZ, the change could translate into a 10 degrees F. increase. Then planes couldn’t take off and people would be stuck in doors in air conditioning all the time.

   TRUMP: “The ice caps were going to melt, they were going to be gone by now, but now they’re setting records. They’re at a record level.” ITV interview.

The  National Snow and Ice Data Center begs to differ.

Trump spoke of “ice caps,” but the Arctic and the Antarctic are  very different systems. The north pole, what with being an ice cap on the ocean surrounded by land, is less complicated than Antarctica, which is a land mass covered by ice and surrounded by ocean.

Most scientists did not predict that the Arctic ice cap would be “gone by now.” They do think it will be gone in a matter of decades.

Figure3-1-750x580.png

As can be seen from the NSIDC map, ice at the Arctic is not “at a record level.” The ice fluctuates month to month and year to year but the long term secular trend is obviously steeply downward. This declining northern ice cover is a direct result of humans farting greenhouse, heat-trapping gases such as carbon dioxide into the atmosphere at the rate of 41 billion metric tons a year! They belch out this nasty, toxic gas by burning coal and gas for heating and gasoline and diesel for transportation.

In 2016,  global sea ice declined so much that we lost a chunk of ice as big as the country of Mexico!

As for Antarctica, it is a land mass with an ice cover.  Its land ice sheets have been losing mass in this century at a worrisome rate.

It is true that the small ring of Antarctic sea ice  was growing slightly in extent in recent decades, but even it suffered a reversal last year. So it too is not at a “record level.” Since Antarctica is a land mass, its thin ring of sea ice isn’t what is significant (unlike in the case of the North Pole or Arctic, which is all sea ice). Antarctica’s sea ice can grow even if the gargantuan ice cover of the continent as a whole is melting. In fact, when  Antarctic ice over land melts and flows into the sea, it adds fresh water to salt water, making it easier for the ocean to freeze. Changes in the ozone layer could also be shifting wind patterns that contribute to a freezing of coastal water. There are also complex relationships between Antarctic weather patterns and the South Pacific.

Anyway, the paid-for denialists that Trump has been listening to have deliberately buried the lede. The story isn’t a little bit of extra sea ice around the continent of Antarctica. The story is the melting of the Antarctic ice pack. And that is not in doubt, any more than the melting of the Greenland ice pack.

20121230_Icesheet_mass_balance_2009_fig2-1.gif

It includes  enormous glaciers that are held back by ice shelves that extend over the ocean. If the ice shelves plop in, that won’t matter much–they are already in the water and so won’t increase sea level if they fall in. But if they release the glaciers, and the glaciers fall into the ocean, that will matter quite a lot. One of those glaciers is so enormous that it could raise sea level several yards/ meters all by itself, in which case say bye bye to Mar-a-lago and Miami and New Orleans and Calcutta, etc.

Humans to Blame for Climate Change, Government Report Says
By Stephanie Pappas, Live Science Contributor |  November 3, 2017

Humans are to blame. That's the verdict of an executive-branch government report concluding that Homo sapiens are the dominant cause of planetary warming since the mid-20th century.

The climate report, released today (Nov. 3), paints a dire picture of the present and future effects of global climate change, from sea levels that could rise by as much as 8 feet (2.4 meters) by 2100, to more-frequent heat waves and other extreme weather events. It is also in stark contrast to climate change stances taken by President Donald Trump, who has ranged from calling it a hoax to saying he had an "open mind" about whether human-caused climate change is actually happening.

"Many lines of evidence demonstrate that it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century," the authors wrote. "Over the last century, there are no convincing alternative explanations supported by the extent of the observational evidence." [6 Unexpected Effects of Climate Change]

For instance, the global seas have risen an average of 7 to 8 inches (17.8 to 20.3 centimeters) since 1900, with nearly half of that (3 inches, or 7.6 cm) occurring since 1993, the report said.

"Human-caused climate change has made a substantial contribution to this rise since 1900, contributing to a rate of rise that is greater than during any preceding century in at least 2,800 years," the report said. "Global sea level rise has already affected the United States; the incidence of daily tidal flooding is accelerating in more than 25 Atlantic and Gulf Coast cities." [Photographic Proof of Climate Change: Time-Lapse Images of Retreating Glaciers]

And things are getting hotter, with annual average temperatures over the contiguous United States increasing by 1.8 degrees Fahrenheit (1 degree Celsius) between 1901 and 2016. And over the next few decades, scientists predict those temperatures will rise by about 2.5 degrees F (1.3 degrees C) relative to the period of 1976 to 2005, the report said.

Assessing the science

The Climate Science Special Report (CSSR) is based on an analysis of peer-reviewed research, publicly available resources, and certain models and data sets related to climate change, according to the report's executive summary. The report was overseen by the U.S. Global Climate Change Research Program, which itself consists of 13 federal agencies that deal with environmental issues, ranging from NASA to the Department of Energy and the Department of State. The group assesses the current state of climate science as part of the National Climate Assessment (NCA) program. The new report is the first volume of the fourth-ever NCA (NCA4). The first NCA was published in 2000, the second in 2009 and the third in 2014.

Ultimately, the U.S. Global Climate Change Research Program is under the oversight of the White House Office of Science and Technology Policy (OSTP). President Trump has yet to name a head for his administration's OSTP. Previous presidents have typically filled the role before they've taken office or within a few months of doing so, according to The Washington Post.

The new report's findings conflict with Trump's stated positions on climate change. Over the years, he has called human-caused climate change a "hoax," including in a 2013 tweet that read, "We should be focused on magnificently clean and healthy air and not distracted by the expensive hoax that is global warming!" During the presidential campaign, Trump was vague on his beliefs about climate change, sometimes indicating he did not believe it was a problem, but telling The New York Times editorial board in 2016 that he had an "open mind" on the issue.

In office, Trump said that the U.S. would withdraw from the Paris Climate Accord, an international agreement that aims to limit global warming to below 3.6 degrees F (2 degrees C) above preindustrial temperatures. The president also nominated Scott Pruitt, a former Oklahoma attorney general who rejects the evidence that human-made carbon dioxide emissions are driving climate change, to head the Environmental Protection Agency (EPA).

Dire warnings

In addition to documenting changes in temperatures and sea levels, the new report warns that heavy rainfall events are increasing across the United States, as are heat waves and forest fires. Reduced snowpack and early spring melt are driving water scarcity in the western U.S., according to the report, threatening to bring about long-term drought by the end of the century.

Atlantic hurricanes are likely to bring greater amounts of precipitation on shore in a warming world and may increase in intensity, according to the report. Small tidal floods have already increased between five-fold and 10-fold since the 1960s in U.S. coastal cities, and the rate of these floods continues to increase in 25 cities along the U.S. Gulf and Atlantic Coasts.

"Without major reductions in emissions, the increase in annual average global temperature relative to preindustrial times could reach 9 degrees F (5 degrees C) or more by the end of this century," the report authors wrote. "With significant reductions in emissions, the increase in annual average global temperature could be limited to 3.6 degrees F (2 degrees C) or less."

Such reductions require a major effort that would need to start rapidly, the report continued.

"After accounting for the temperature effects of non-CO2 species [such as methane], cumulative global CO2 emissions must stay below about 800 GtC [gigatons of carbon] in order to provide a two-thirds likelihood of preventing 3.6 degrees F (2 degrees C) of warming," the authors wrote. "Given estimated cumulative emissions since 1870, no more than approximately 230 GtC may be emitted in the future in order to remain under this temperature limit."

As is, the authors wrote, emissions are likely to surpass that level within two decades.

Protect Democracy and Union of Concerned Scientists file suit against EPA over attempt to delegitimize science
January 23, 2018

Independent facts and institutions, and the open exchange of accurate scientific information, are touchstones of a functioning democracy. Anti-democratic regimes often seek to delegitimize and suppress authoritative voices that offer accurate information, especially if it can be used to criticize the government. President Trump and his administration have shown authoritarian tendencies in many ways, including a demonstrated hostility to science and to developing policy based on impartial and balanced scientific evidence. Recent particularly harrowing examples include subjecting traditionally independent EPA grant funding to political review, and EPA scientists being pulled from public events addressing critical national challenges, apparently because of their scientific views.

Today, Protect Democracy and Jenner & Block represented the Union of Concerned Scientists (UCS) and an individual advisory committee member in filing suit against the U.S. Environmental Protection Agency (EPA), challenging one such attempt by the administration to delegitimize science and scientists: EPA Administrator Scott Pruitt’s Directive removing academic and non-profit scientists who receive EPA grants from EPA advisory committees. In October, Pruitt announced that he would exclude anyone from serving on any of the twenty-three EPA scientific advisory committees if they had received EPA grants to fund any of their research. The Directive is arbitrary, without any factual or legal grounding, and violates the Federal Advisory Committee Act, which requires advisory committees to be fairly balanced and protected from inappropriate influence by the appointing authority.

As the suit explains, the Directive is an attack on science itself. By accusing academic and non-profit grant-funded scientists of having a conflict of interest, Pruitt seeks to portray legitimate, independent scientists—who provide accurate, evidence-based information backed by verifiable, peer-reviewed research in order to inform environmental policy—as just another interest group seeking to advance an agenda. But the EPA should have no vested interest in the outcome of EPA grant-funded research; grant recipients perform independent scientific research and are not beholden to the EPA for any particular result. The EPA’s interest is in obtaining accurate information in order to make the best policy; scientists on advisory committees provide just that—whether or not they receive EPA grants. Certainly, academic and non-profit scientists have significantly less to gain from agency action (or inaction) than the private industry representatives with whom they are being replaced.

The ability of ordinary citizens to participate in robust public discourse and to hold government leaders accountable requires a baseline agreement about fundamental facts. Anti-democratic regimes thrive on obfuscating truth—in part, by seeking to delegitimize and suppress authoritative voices that offer accurate information that can be used to inform the public or criticize the government.  Scientists are often a target of such efforts. This unprecedented Directive is an attempt to delegitimize and suppress the role of academic scientists advising the agency and, by extension, the results of their research.

American policymakers, businesses, and the American public must be able to trust that the government’s policies are grounded in fact-based analysis. A policy that excludes the nation’s most eminent scientists not only silences key, unbiased voices in EPA policy development, but signals government disapproval of the former committee members’ work—including, for example, critical climate change research. Government suppression and delegitimization of scientists and scientific research is anti-democratic and impedes the American public’s ability to knowledgeably engage with pressing national issues.

Scientists Sue EPA Over Advisory Board Changes
Administrator’s Directive Defies the Law, Undermines Science Americans Depend On

Today, a group of scientists filed suit against the U.S. Environmental Protection Agency (EPA) for changing the makeup of its advisory boards to limit the participation of scientists from academia and nonpartisan non-profit organizations. EPA Administrator Scott Pruitt announced in October that he would exclude anyone from serving on any of the 23 EPA scientific advisory boards if they had received EPA grants to fund any of their research. The directive is arbitrary, without any factual or legal grounding, and violates the Federal Advisory Committee Act, which requires advisory committees to be fairly balanced and protected from inappropriate influence by the appointing authority, according to the lawsuit. As the suit explains, the open exchange of accurate scientific information is a touchstone of a functioning democracy.

The lawsuit was filed in the United States District Court for the District of Massachusetts by Protect Democracy, a nonpartisan nonprofit organization, and the law firm Jenner & Block, representing the Union of Concerned Scientists and Dr. Elizabeth A. (Lianne) Sheppard, professor at the University of Washington School of Public Health.

“This is an abuse of power and an affront to the scientific integrity of the EPA and the federal government.” said Joshua Goldman, senior legal analyst for the Union of Concerned Scientists. “This directive singles out scientists from the nonprofit and academic sector—recognized experts in their field who want to serve the public—and asks them to choose between public service and their scientific work. It’s another example of this administration’s hostility to independent scientific input and basing policy on impartial and balanced scientific evidence. The directive inherently prevents the agency from receiving independent scientific advice, and erects unnecessary barriers to scientists who want to use their expertise to serve the public.

“The EPA hasn’t bothered to make the case for why EPA grants create a conflict of interest. Mr. Pruitt simply can’t justify this decision, especially when there are no such restrictions on scientists who get funding from the industries the EPA oversees.”
The lawsuit is vital because undermining scientific advisory committees weakens an important check on the administration’s decisions.
“Anti-democratic governments thrive on obfuscating truth and seeking to suppress scientists and other authoritative voices that offer accurate information,” said Protect Democracy counsel Jamila Benkato. “The EPA’s directive is one more example of the administration’s assault on facts.”

The directive unfairly excludes scientists from the role they should play in policymaking, according to the plaintiffs.
“I am committed to serving on federal advisory committees because I believe this is one of the most effective ways for me to use my scientific expertise to promote public health,” said Dr. Sheppard. “This directive forces me to choose between my own work and my commitment to the public.”

The lawsuit asks the court to overturn Pruitt’s directive and prevent EPA staff from implementing the directive.
“When we ban America’s top scientists from providing their expertise to the EPA, we all suffer,” said Goldman. “EPA advisory boards examine vital questions, like what makes for unsafe levels of pollution in the air and the amount of chemical exposure that constitutes a health risk. EPA rules need to be based on the best available science. This directive fundamentally undermines the EPA’s ability to carry out its mission of protecting all Americans.”

The Union of Concerned Scientists puts rigorous, independent science to work to solve our planet's most pressing problems. Joining with people across the country, we combine technical analysis and effective advocacy to create innovative, practical solutions for a healthy, safe, and sustainable future.

UCS Sues to Stop EPA from Kicking Independent Experts Off Advisory Boards
Josh Goldman, senior policy analyst, Clean Vehicles | January 23, 2018

The Union of Concerned Scientists and Protect Democracy – a legal non-profit dedicated to preventing our democracy from declining into a more authoritarian form of government – have teamed up to challenge EPA Administrator Scott Pruitt’s directive that would ban anyone from serving on EPA advisory boards if they receive EPA grant funding. Under the guise of improving advisory board balance, Pruitt is using this directive to populate advisory boards with industry-funded scientists and state government officials who have made a career fighting federal regulations. The EPA Science Advisory Board, for example, now includes fourteen new members who consult or work for the fossil fuel or chemical industries, which gave Pruitt nearly $320,000 for his campaigns in Oklahoma as a state senator and attorney general.

Banning EPA grant recipients from EPA advisory boards excludes academic scientists from serving on EPA advisory boards in particular, since academics often rely on outside funding – from EPA or elsewhere – to conduct research, fund graduate students, and work in the public interest. For example, EPA grants have funded research linked with projects that: protect children who are at-risk for lead poisoning in Indiana, restore coastal forests in Connecticut, and maintain clean drinking water in Mississippi. It’s hard to argue why conducting research in support of these types of projects would make someone provide biased advice to EPA, yet that’s the reasoning that Pruitt uses to justify this directive. The reality is that industry-funded science tends to be biased, not science from independent academic institutions.

The scientists that Pruitt has removed from EPA advisory boards also happen to be some of our country’s best. Those already dismissed include a Fulbright Scholar and a member of the National Academy of Sciences Institute of Medicine, for example. Pruitt has replaced these leaders with scientists who work for the fossil fuel, tobacco, and chemical industries and have a history of downplaying the health risks of secondary smoke, air pollution, and other public health hazards.

The real reasoning behind this directive is to make it easier for Pruitt to delay, rollback, or dismantle the EPA regulations that are designed to protect clean air, water, and public health. As we begin 2018, EPA is reconsidering rules that would address: the high asthma and cancer rates caused by heavy-duty trucks on busy roadways, the huge amount of global warming emissions from passenger vehicles, and the outdated emergency response requirements for facilities that store explosive or hazardous chemicals. These types of regulations rely on advise from EPA advisory boards, which are now more likely to support Pruitt in loosening rules that cover the industries tied to the new EPA advisory board members.

Our suit challenging the advisory board directive, filed in the United States District Court for the District of Massachusetts, alleges that the Pruitt directive is arbitrary and capricious (legalese for b.s.), and has no basis in law or EPA precedent. Our complaint also details how this directive violates the Federal Advisory Committee Act, which requires all advisory committees to be “fairly balanced,” and not be “inappropriately influenced” by the appointing authority.

I’ll keep you posted on how this suit develops. In the interim, if you have received EPA funding or have served on an EPA advisory committee, send me your story at (jgoldman@ucsusa.org).

Even if you aren’t an EPA-connected expert, check out how you can get more involved in the fight against Pruitt’s anti-science crusade by visiting the UCS action center. This Administration needs to hear from everyone, not just scientists, and UCS provides a platform for you to join the hundreds of thousands of UCS supporters across the country in standing up for independent scientists and an EPA that seeks to protect public health, not industry profits.

The Science Jury Is In. Global warming is real and human activity is driving it.   There is nothing left to seriously debate on this matter.   One might as well debate those who believe the Earth is flat.

Scientific consensus: Earth's climate is warming

Multiple studies published in peer-reviewed scientific journals1 show that 97 percent or more of actively publishing climate scientists agree*: Climate-warming trends over the past century are extremely likely due to human activities.


American Association for the Advancement of Science
"The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society." (2006)

American Chemical Society
"Comprehensive scientific assessments of our current and potential future climates clearly indicate that climate change is real, largely attributable to emissions from human activities, and potentially a very serious problem." (2004)

American Geophysical Union
"Human‐induced climate change requires urgent action. Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes." (Adopted 2003, revised and reaffirmed 2007, 2012, 2013)

American Medical Association
"Our AMA ... supports the findings of the Intergovernmental Panel on Climate Change’s fourth assessment report and concurs with the scientific consensus that the Earth is undergoing adverse global climate change and that anthropogenic contributions are significant." (2013)

American Meteorological Society
"It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide." (2012)

American Physical Society
"The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now." (2007)

The Geological Society of America
"The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s." (2006; revised 2010)


U.S. Global Change Research Program
"The global warming of the past 50 years is due primarily to human-induced increases in heat-trapping gases. Human 'fingerprints' also have been identified in many other aspects of the climate system, including changes in ocean heat content, precipitation, atmospheric moisture, and Arctic sea ice." (2009)

Intergovernmental Panel on Climate Change
“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen.”

“Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems.”

Yet another right-wing propaganda hit piece on Space X.   This time from the Washington Times newspaper.

The hidden fees of Space
By Peter Weyrich
January 17, 2018
Washington Times

No one likes hidden fees. From unauthorized phone charges to home closing costs and prepaid card levies, they take a toll on low and middle-income Americans. To mitigate consumer outrage, members of Congress often demagogue unknown expenditures like ATM and airline baggage fees in committee hearings; costs which usually do not amount to more than a few dollars.

While some of these nominal fees are distasteful, at least consumers ultimately come to terms with them. Unfortunately, this is not always the case when dealing with the federal government, especially on high-ticket items. In fact, last week, one aerospace manufacturer may have incurred unanticipated costs to the tune of tens of millions or even billions on our bills, and yet the government is refusing to even disclose if there are any. Most members of Congress have yet to say a word.

SpaceX recently conducted Project Zuma, a secret mission involving a secret payload for a secret government agency. Some believe that costly problems occurred with the flight, although no one is certain on this point either because the outcome is apparently a secret, too.


Given that this mission involves taxpayer dollars, reporters and activists have been demanding answers. In the middle of last week, a reporter for Bloomberg pressed the Pentagon, asking: “This is a billion-dollar satellite. It’s been four days. Was it a success or a failure? And what’s the fate of the satellite?” Declining to answer, they advised him to refer all questions to SpaceX.

This suggestion was not taken very seriously. Asking a launch provider if it failed is the equivalent of querying a politician on potential wrong-doings. Instincts naturally tell both to deny everything.

After all, Washington didn’t exactly decide on the most reliable business available for this secret yet ostensibly important mission; it picked one deserving of quite a few poor Yelp reviews. In 2015, SpaceX’s Falcon 9 exploded while operating on a $110 million government contract. In 2016, it blew up while on a $62 million government contract, destroying a $205 million Facebook satellite in the process. To say the least, it wouldn’t be very shocking if the Falcon 9 failed to operate as intended again in 2018.

Meanwhile, just days after this SpaceX launch, the United Launch Alliance (ULA) completed its 124th-consecutive successful mission for the National Reconnaissance Office (NRO) — a substantial comparative difference. Is it time to cut off funding or put SpaceX on the back-burner until it matures into a more reliable contractor? At a minimum, the government should aggressively pursue answers as to why SpaceX seems to have so many more costly explosions and mission failures than its competitors.

Taxpayers are tired of getting ripped off. Perhaps SpaceX does indeed have some value on the marketplace — it does often offer cheaper rockets — but it’s hard to gauge its worth when the government seems to always shield the company’s problems from the public’s view.

Some argue that this favoritism has existed for years, not weeks. For example, NASA has still not released a detailed, public report of SpaceX’s 2015 explosion even though it released one of the company’s competitor, Orbital ATK. Rep. Lamar Smith was right on target when he said this “raises questions about not only the equity and fairness of NASA’s process for initiating independent accident investigations, but also the fidelity of the investigations themselves.”

There are definite potential motives for these suspected hide-and-seek games. Since the Tea Party Massacre, Americans have always been the de facto market regulators; the “invisible hands” working behind the scenes to ensure quality control. When the mobs decry a dishonest politician, he or she is voted out of office. When enough speak out against a practice in Washington, things change. But none of this can occur without public knowledge, something that SpaceX-favoring bureaucrats likely know all too well.

If the government wants to continue using providers that may be providing sub-par performance, that’s its prerogative. At the very least, though, it owes the masses truth and transparency.

Without it, America is no longer operating as a democratic republic. No information means no public voice, while the megaphones of politicians and bureaucrats continue to expand.

There is nothing less American than this, and it should change right now — this week — with an explanation of what happened with the Zuma mission. The American people deserve to know. After all, it’s their money that’s on the line, and their national security that’s at risk.

This is the taxpayers’ money we’re talking about. Doesn’t the government owe them the truth?

SpaceX and customers defend Falcon 9 performance after Zuma mission
by Jeff Foust — January 17, 201
Space News

SpaceX reiterated at a congressional hearing Jan. 17 that its Falcon 9 rocket performed as expected on its most recent launch, despite swirling questions about the potential failure of the classified Zuma mission.

SpaceX, though, now has the support of the customer for its next commercial launch, who said it was “confident” that SpaceX would be ready for the late January mission.

In a tweet Jan. 17, SES said it reviewed data from the Jan. 7 Falcon 9 launch of Zuma and concluded that the vehicle had performed as expected, clearing the way for the launch of GovSat-1, a joint venture of SES and the government of Luxembourg, on another Falcon 9 currently scheduled for Jan. 30.

“Following Zuma mission, our engineering staff have reviewed all relevant launch vehicle flight data following last Falcon-9 launcher mission,” the company tweeted. “We are confident on SpaceX readiness & set for Govsat-1 launch late Jan!”

The comment by SES came several hours after a SpaceX executive defended the vehicle’s performance in response to questions by members of the House space subcommittee during a hearing on NASA’s commercial crew program, for which SpaceX is one of two companies developing vehicles.

Rep. Brian Babin (R-Texas), chairman of the subcommittee, raised the issue of the status of the Zuma mission in the first question after opening statements. Babin noted he was restricted in what could be discussed during a public, unclassified hearing, “but circumstances surrounding this mission do have a direct impact on NASA and this committee’s jurisdiction and oversight responsibilities.”

“Falcon 9 performed as specified. It actually performed very well,” said Hans Koenigsmann, vice president of build and flight reliability at SpaceX. “We’re picking up the launches by the end of the month, as we planned.”

Actions by Falcon 9 customers appear to support the assessment that the launch went according to plan. In addition to the SES statement, Space Systems Loral announced Jan. 16 that it had shipped the Hispasat 30W-6 spacecraft, which it built for satellite operator Hispasat, to Cape Canaveral for launch on a Falcon 9. That launch is expected in mid-February.

SES announced Jan. 11 that GovSat-1, built by Orbital ATK, had arrived at Cape Canaveral for its upcoming launch. Industry officials say it’s unlikely the operators would agree to ship the satellites to the launch site if they believed that their upcoming launches were in danger of being delayed because of any investigation into the Zuma mission.

Other customers have stood behind SpaceX. In a series of tweets Jan. 11, Matt Desch, chief executive of Iridium, said he believed that SpaceX was not responsible for any failure of the Zuma mission, and criticized media coverage of the launch. SpaceX has successfully launched 40 of Iridium’s next-generation satellites on four Falcon 9 missions, with four more launches scheduled for 2018 to launch the remaining 35.

“I believe SpaceX statements, and have my own beliefs about what probably happened,” he wrote in one tweet. “Just find it sloppy and lazy to blame SpaceX when others more likely at fault (but won’t/can’t talk).”

Breitbart, other conservative outlets escalate anti-SpaceX campaign
In Washington DC, politics sometimes matter more than a rocket's power or price.
by Eric Berger - 11/1/2017
ARS Technica

The articles began appearing in late August, mostly in conservative publications such as Town Hall, Breitbart, and the Daily Caller and have since continued to trickle out through October. All of the dozen or so Web commentaries, variously styled as op-eds or contributions, have made the same essential point—that Elon Musk is benefiting from crony capitalism and must be stopped.

This is not a particularly new line of attack against Musk, especially among some conservatives who decry the public money his companies have received to build solar power facilities, electric cars, and low-cost rockets. Yet most of these articles have been quite specific in their attacks, pinpointing a single section in the 2018 National Defense Authorization Act as particularly troublesome to the Republic.

The articles, several of which are written by former US Rep. Ron Paul or his associates, have the same general theme: Musk has given lavishly to politicians, especially Arizona Senator John McCain (R). In return, McCain added Section 1615 to this year's defense authorization bill, which includes language to restrict the military from investing in new launch systems. With this language, the articles assert, Musk seeks a monopoly on the US national security launch market. In addition to saying this allows Musk to fleece taxpayers, some of the more overdone authors assert that it could kill Americans.

Ars spoke with half a dozen industry officials about these op-eds on background to try to discern who or what was behind them. SpaceX declined comment. A spokeswoman for ULA did not respond to a request for comment about these articles. One source speculated that there are probably several stakeholders behind this Astroturf-like activity.

"This is business as usual," one aerospace industry source said of the litany of anti-SpaceX commentaries. "I don’t think it is that effective. It’s like going to a space conference and it’s a bunch of space people that hear what they expect to hear with no new listeners."

Why SpaceX Is The Snake Oil Peddler Of The Twenty-First Century
Worrisome national security events have convinced some Americans that SpaceX is the magic elixir of this generation. But this time our national security is at stake.
by Beau Rothschild
January 16, 2018
The Federalist

In the nineteenth century, Americans across the country were mesmerized by “miracle elixirs,” better known as medicine shows, which offered “cure-alls” for everything in the book. Diseases? There was a drink for that. Wrinkles? There was a magic cream for that too. These traveling shows did far more than “heal,” they entertained. Freak shows, magic tricks, and storytelling, among other fun activities, were included on the lists of offerings.

For many, these flamboyant events were awe-inspiring – that is, until the country realized these “miracle cures” were almost completely ineffective. Over time, an increasing number of Americans began referring to these big promisers as “snake oil salesmen.” By the next century, most disappeared, as did their outrageous claims.

Worrisome national security events that transpired this week have convinced some Americans that SpaceX, a rocket manufacturer and launcher for national security missions, is the magic elixir of this generation — only this time, the “magic pills” in question are not only often ineffective, they’re also affecting the country’s national security.

Akin to the once-beloved nineteenth-century miracle workers, SpaceX often tries to entertain onlookers with flashy proclamations. It has pledged nearly unfeasible feats, such as sending humans beyond the Moon by the end of the year and potentially landing spaceships on Mars by 2022 — both of which will allegedly occur on rockets that have either failed to get off the ground or have had trouble doing so. It is not without a sense of irony that the CEO of SpaceX suggested those few who decide to go to Mars may not live to tell about it.

It is hard to criticize SpaceX’s public relations strategy. After all, it is competing against some of America’s most prominent companies, so drumming up eye-popping media coverage is a must. But past and possible present operational concerns have led some to seriously question the company.

SpaceX attempted to launch a billion-dollar classified government satellite on Sunday, coined “Zuma,” for an unknown government agency. No one knows if it succeeded, but many have expressed skepticism, citing possible errors on SpaceX’s end.

There is plenty of reason for concern on the part of SpaceX, primarily because of past issues with the Zuma mission itself. Zuma was initially set to launch in November, but experienced several delays before its Jan. 7 launch. Also of note is that SpaceX’s Falcon 9, the rocket used for this mission, has massive past failures under its belt.

Regardless of mission sensitivity, the U.S. government is always expected to shed some light on issues like this one. But this time, a top Pentagon spokeswoman, perhaps a stalwart defender of SpaceX like her former boss, Sen. John McCain (R-Ariz.), refused to comment. She told incredulous journalists to refer all inquiries to SpaceX.

Predictably, SpaceX has assured the press that everything went smoothly on its part, similar to how it casted blame on the strut obtained from an outside company during 2015’s Falcon 9 failure. It also refused to rule out the merits of pointing fingers at external forces in another Falcon 9 mishap one year later.

It would be one thing if this was a fluke misjudgment on the Pentagon’s part, but government bureaucrats seem to have a track record of hiding SpaceX’s mistakes. For example, during the 2015 Falcon 9 incident, NASA refused to release a public investigative summary, despite originally promising it would do so. Although it put out a report for a competitor’s similar commercial launch which operated under the same NASA program, it kept this SpaceX case study a public mystery.

Do certain government officials fear learning the truth? Are they so caught up in Elon Musk’s praiseworthy end-game and objectives that they are willing to cast a blind eye to these seeming problems?

Investigations typically take months to years, so it is unlikely that bureaucrats have reached an unequivocal answer already. Yet, as if nothing has happened, SpaceX has said that it will continue full-speed ahead with the launches on its agenda, including the Falcon 9 Heavy — the rocket that will allegedly fuel its quest for Mars despite 4 years of delays and a failure last month. SpaceX may also send astronauts to the International Space Station by the end of 2018.

While it is easy to grow starry-eyed and all-believing due to SpaceX’s praiseworthy intent, government officials must remain free of bias when making crucial national security decisions, especially when human lives are at stake. Perhaps it’s time for them to take a step back and let rationality kick in.

The magic elixirs of 200 years ago weren’t miracle workers, and neither is SpaceX — at least not yet. Whether SpaceX can overcome their failures remains to be seen, but it is concerning, to say the least, that American taxpayers have become the guinea pigs who will bear the risks and the costs before a final determination can be made.

SpaceX should continue working to improve — and over the past year, improve it certainly has — but not on the taxpayers’ dime. It’s time to put launches from this big dreamer on pause until it demonstrates steady, proven success.

What’s causing SpaceX’s Falcon Heavy delays?
By Eric Ralph
January 16, 2018

Although uncertainty in the schedule remains, SpaceX’s Falcon Heavy rocket appears to be nearly ready for its first engine ignition test (called a ‘static fire’) sometime within the next week or so.

An attempt at 1 PM EST today, January 16, was canceled for unspecified reasons, although Kennedy Space Center reportedly maintained the usual roadblock to prevent vehicles from driving past, implying that SpaceX still intends to conduct propellant loading tests with Falcon Heavy. It was noted earlier this morning by spaceflight journalist Chris Bergin that things were “a bit too quiet” if a test was indeed planned for today, and his intuition appears to have been correct. It still remains the case that Falcon Heavy is an experimental and untested rocket to an extent, and these delays are to be expected as SpaceX works out the inevitable kinks and bugs that arise during the extensive testing big launch vehicle has been and is still being put through.

Due to range requirements in support of an upcoming launch of the United Launch Alliance’s (ULA) Atlas 5 rocket, currently NET Thursday, SpaceX has postponed the static fire of Falcon Heavy without a replacement date. It is unlikely that another attempt will occur before the upcoming weekend, but SpaceX should have at least a solid week of uninterrupted range support once ULA’s launch occurs, hopefully without delay. Godspeed to ULA, in the meantime.

The crazy complexity of rocketry

Most recently, and perhaps somewhat related to Falcon Heavy’s static fire delays, SpaceX completed as many as two complete wet dress rehearsals (WDRs), which saw Falcon Heavy topped off with full tanks of its cryogenic (super cool) liquid oxygen (LOX) and rocket-grade jet fuel (RP-1). In essence, the rocket became equivalent to several hundred tons of carefully stabilized explosive. Nominally, these rehearsals appear entirely uneventful to an outside observer, with little more than ice formation and the occasional bursts of propellant tank vents to suggest that something important is occurring. However, anomalies like the failure of Falcon 9 during the Amos-6 static fire provide a staggering demonstration of just how explosive and sensitive a rocket’s fuel is, and Falcon Heavy has approximately three times the fuel capacity of Falcon 9. Empty, Falcon 9’s mass has been estimated to be around 30 metric tons, a minuscule amount of structure in the face of the more than 500 metric tons of propellant the vehicle carries at liftoff.

These propellant loading tests can also be challenging for reasons aside from their highly explosive nature. Due to basic realities of the physical nature of metal, the predominate ingredient for Falcon 9’s load-bearing structures, metallic structures shrink under extreme cold (and expand under heating). In the case of Falcon 9’s massive 45 meters (150 foot) tall first stage, the scale of this contraction can be on the order of several inches or more, particularly given SpaceX’s predilection towards cooling their propellant as much as possible to increase its energy density. For Falcon 9, these issues (thermodynamic loads) are less severe. However, add in three relatively different first stage boosters linked together with several extremely strong supports at both their tops and bottoms and that dynamic loading can become a fickle beast. The expansion or compression of materials due to temperature changes can create absolutely astounding amounts of pressure – if you’ve ever forgotten a glass bottled drink in the freezer and discovered it violently exploded at some future point, you’ll have experienced this yourself.

With several inches of freedom and the possibility that each Falcon Heavy booster might contract or expand slightly differently, these forces could understandably wreak havoc with the high precision necessary for the huge rocket to properly connect with the launch pad’s ground systems that transmit propellant, fluids, and telemetry back and forth. Two reliable Kennedy Space Center sources experienced with the reality of operating rockets suggested that issues with dynamic loads (such as those created by thermal contraction/expansion) are a likely explanation for the delays, further evidenced by their observations that much of the pad crew’s attention appeared to be focused at the base of Transporter/Erector/Launcher (TEL). The TEL base hosts the clamps that hold the rocket down during static fires and launches, as well as the Tail Service Masts (TSMs) that connect with the Falcon 9/Heavy to transport propellant and data to the first stage(s). These connection points are both relatively tiny, mechanically sensitive, and absolutely critical for the successful operation of the rocket, and thus are a logical point of failure in the event of off-nominal or unpredicted levels of dynamic stresses.

Test, launch, land, repeat.

All things considered, these difficulties demonstrate that even after months (even years) of relentless modeling, testing, remodeling, and retesting, rockets (and especially huge rockets like Falcon Heavy) are immensely complex, and even tiny mistakes can lead the vehicle to stray from its expected behavior. Quite simply, the reality of engineering only truly comes into play once hardware is fully in the loop, and it’s in this state that SpaceX has demonstrated again and again a distinct and elegant ability to learn from their hardware, rather than attempt to salve uncertainty with a neurotic and counterproductive level of statistical analysis, modelling, and documentation. The agile launch company still dabbles in those aspects when beneficial or necessary, but testing comes first in its importance.

The conclusion here, then, is that Falcon Heavy’s delays betray this aspect of SpaceX – a launch company that loves its fans, but also understands the need for cautious testing when it comes to new and untried rocket hardware. Whether Falcon Heavy succeeds or fails, SpaceX will learn from the proceedings, and they will be better off for it (although maybe less so financially…).

Zuma Blame Game Begins
January 16, 2018
Parabolic Arc


“The first statement by SpaceX was that the failure to achieve orbit was not theirs” so there’s no reason so far to question the company’s planned participation in NASA space projects, Senator Bill Nelson of Florida, a former astronaut and the top Democrat on the Senate Commerce, Science and Transport Committee, said Wednesday before being briefed…

Meanwhile, SpaceX’s critics in Congress are questioning the company’s reliability.

Republican Senator Richard Shelby of Alabama, who heads the panel that approves appropriations for NASA, said the lost satellite raises new questions about SpaceX contracts. Shelby is a strong supporter of United Launch Alliance, which has operations in his state.

“The record shows they have promise, but they’ve had issues as a vendor,” Shelby said Wednesday, referring to SpaceX. “United Launch, knock on wood, they’ve had an outstanding record.”

SpaceX Customer Blames Northrop Grumman for Missing Satellite
By Dana Hull
January 11, 2018
Bloomberg Technology

A major SpaceX customer spoke up for Elon Musk’s rocket company, pinning the blame for a secret military satellite’s disappearance on defense company Northrop Grumman Corp.

Matt Desch, chief executive officer of satellite operator Iridium Communications Inc., said that as the launch contractor, Northrop Grumman deserves the blame for the loss last weekend of the satellite, which is presumed to have crashed into the ocean in the secretive mission code-named Zuma.

“This is a typical industry smear job on the ‘upstart’ trying to disrupt the launch industry,” Desch said on Twitter Thursday in response to a news article. “SpaceX didn’t have a failure, Northrop Grumman did. Notice that no one in the media is interested in that story. SpaceX will pay the price as the one some will try to bring low.”

Northrop Grumman didn’t immediately respond to requests for comment. Desch later told Bloomberg in a message that he didn’t know for sure what led to the disappearance but was speculating that a dispenser failed to release the satellite, which he said would have been Northrop Grumman’s responsibility.

Scientists Discover Clean Water Ice Just Below Mars' Surface
by Robbie Gonzalez
January 11, 2018
Wired.com

Locked away beneath the surface of Mars are vast quantities of water ice. But the properties of that ice—how pure it is, how deep it goes, what shape it takes—remain a mystery to planetary geologists. Those things matter to mission planners, too: Future visitors to Mars, be they short-term sojourners or long-term settlers, will need to understand the planet's subsurface ice reserves if they want to mine it for drinking, growing crops, or converting into hydrogen for fuel.

Trouble is, dirt, rocks, and other surface-level contaminants make it hard to study the stuff. Mars landers can dig or drill into the first few centimeters of the planet's surface, and radar can give researchers a sense of what lies tens-of-meters below the surface. But the ice content of the geology in between—the first 20 meters or so—is largely uncharacterized.

Fortunately, land erodes. Forget radar and drilling robots: Locate a spot of land laid bare by time, and you have a direct line of sight on Mars' subterranean layers—and any ice deposited there.

Now, scientists have discovered such a site. In fact, with the help of HiRISE, a powerful camera aboard NASA's Mars Reconnaissance Orbiter, they've found several.

In this week's issue of Science, researchers led by USGS planetary geologist Colin Dundas present detailed observations of eight Martian regions where erosion has uncovered large, steep cross-sections of underlying ice. It’s not just the volume of water they found (it's no mystery that Mars harbors a lot of ice in these particular regions), it’s how mineable it promises to be. The deposits begin at depths as shallow as one meter and extend upwards of 100 meters into the planet. The researchers don't estimate the quantity of ice present, but they do note that the amount of ice near the surface is likely more extensive than the few locations where it's exposed. And what's more, the ice looks pretty damn pure.

NASA calls the use of space-based resources “in-situ resource utilization,” and the agency thinks it will be essential to survival in deep space. Of particular interest to ISRU planners is the depth of the ice, and the ratio of pure ice to that mixed in with bits of Mars regolith. The more pristine the ice, and the closer it is to the surface, the less energy it takes to extract and use.

The ice found this time isn’t crystal clear. Over years, observations showed that the ice is slowly surrendering water to the atmosphere through a process called sublimation, and signs suggest that boulders and sediment are dislodging from the ice as it recedes. But some debris is to be expected. Dundas and his colleagues hypothesize that the ice originated as snow, falling in waves over millions of years. Some rocky material probably found its way in, in between snow events—but the surrounding ice, the researchers think, is relatively clean.

"On Mars, when you see something bright, it usually means ice,” says Richard Zurek, chief scientist for the Mars Program Office at NASA's Jet Propulsion Laboratory, who was unaffiliated with the study. Most of the material on Mars reflects little light, "but the albedo readings on these exposed sections show that this is very bright stuff," he says. "And the spectrometer readings support that this is water ice and not ice-cemented soil, which would be much harder to convert into water as a resource."

Now, don't pack your bags for Mars just yet. The eight sites Dundas and his colleagues observed were all located at upper mid-latitudes, between 55 and 60 degrees north or south of the equator, where temperatures can drop extremely low. Most Mars missions, though, restrict their landing sites to within 30 degrees of the equator—as would future crewed missions to the planet's surface, most likely. As Zurek puts it: "If you wanna stay warm, it's better to be in Hawaii than Alaska."

But that close to the equator, warmer temperatures could drive subsurface ice reserves deeper into the ground, where they'll be harder to get to. "So that's something you'll want to follow up on and investigate before you put your base down," Zurek says.

Plans to do so are already in the works. "I'm sure we haven't found all of the exposures at this point," Dundas says, and more could certainly exist closer to the equator. NASA's Mars 2020 rover is equipped with a ground-penetrating radar that could allow it to probe the mysterious upper layers of the planet's surface. The European Space Agency's ExoMars rover, also slated for a 2020 launch, will come outfitted with a drill designed to sample geology at depths of up to two meters.

Another option: artificial meteors. Scientists imagine sending spacecraft to hitch a ride through Mars' atmosphere on larger vehicles, only to break off at low altitude and collide with the planet. They'd land with enough impact to bury themselves a few meters into the planet's surface, detect the composition of the area around them, and relay their observations back to Earth by way of satellites in Mars orbit. "That one, the technology's not quite there yet, but it's rapidly developing," Zurek says.

Fortunately, scientists still have some time to pinpoint Mars' reservoirs of water ice. Humans will likely return to the moon before they venture into deep space. Optimistic timelines put our arrival on the Red Planet some time during the 2030s. Where we land, how long we visit, and what we bring along will all depend on the resources that await us—and how hard we'll have to work to get them.

Is SpaceX to blame, then?

Perhaps not. "As of right now reviews of the data indicate Falcon 9 performed nominally," a company spokesperson told Ars. It is important to note that the payload adapter, which connected the Zuma payload and its fairing to the rest of the rocket, was supplied by Northrop Grumman, rather than by SpaceX. If there was some kind of separation problem, the fault may not lie with SpaceX, but rather Northrop Grumman.

Did SpaceX’s secret Zuma mission actually fail?
Conflicting reports say the satellite fell out of the sky
By Loren Grush

When reached for comment, SpaceX said that the Falcon 9 rocket, which carried Zuma to orbit, performed as it was supposed to. “We do not comment on missions of this nature; but as of right now reviews of the data indicate Falcon 9 performed nominally,” a SpaceX spokesperson told The Verge. A lot of information is packed in that statement. SpaceX is essentially saying that the Falcon 9 pulled off all the tasks it’s supposed to perform during a mission. That typically includes launch, the separation of the rocket’s two stages, and deployment of the satellite into its intended orbit. And as viewers saw Sunday night, the Falcon 9’s first stage pulled off another successful landing after launch — indicating that the rocket was in full working order.

This morning, SpaceX’s president and COO Gwynne Shotwell doubled down on SpaceX’s original statement. “For clarity: after review of all data to date, Falcon 9 did everything correctly on Sunday night,” she said. “If we or others find otherwise based on further review, we will report it immediately. Information published that is contrary to this statement is categorically false.” She added that the company cannot comment further due to the classified nature of the mission.

So what actually happened? No one is saying for certain, but there are a couple scenarios in which the Falcon 9 could have performed as it was supposed to and the spacecraft didn’t deploy correctly. Typically, SpaceX uses its own hardware on top of its rocket to send a satellite into orbit, what is known as a payload adapter. It’s an apparatus that physically separates the satellite from the upper part of the rocket and sends it into orbit. However, a previous report from Wired noted that Northrop Grumman provided its own payload adapter for this mission. And if that payload adapter failed, it would have left the satellite still attached to the upper portion of the rocket. That’s certainly a mission failure, but it wouldn’t necessarily be the fault of the Falcon 9.

Of course, Northrop Grumman won’t comment on the launch. “This is a classified mission. We cannot comment on classified missions,” Lon Rains, communications director for Northrop, said in a statement to The Verge. But a payload adapter failure would explain a lot: it would mean the spacecraft and the rocket’s upper stage made it to orbit still attached, where they were picked up by Strategic Command’s tracking. Then the two somehow de-orbited, on accident or maybe even on purpose — it’s possible SpaceX used the rocket to send the pair careening toward Earth, since Zuma was not designed to live in orbit with a rocket strapped to its back.

Until someone speaks on the record, it’s hard to know for sure. Meanwhile, SpaceX is pretty pleased with the launch. The company has been tweeting pictures from the mission, indicating that all went well. Plus, SpaceX rolled out its new Falcon Heavy rocket to its primary launchpad for an upcoming test, which probably wouldn’t have happened if there was a major issue with the company’s rocket hardware. “Since the data reviewed so far indicates that no design, operational or other changes are needed, we do not anticipate any impact on the upcoming launch schedule,” Shotwell added in her statement. “Falcon Heavy has been rolled out to launchpad LC-39A for a static fire later this week, to be followed shortly thereafter by its maiden flight.”

I read somewhere that the Chinese space station has already begun to fall back to earth....They are good at cloning what they see and even better at gaining access to key technology to make it happen....

China's first space lab Tiangong-1 which was launched in 2011 is plunging out of orbit later this year. 

China orbited its second space lab,  Tiangong-2, in 2016.

They will begin construction of their first space station, Tianhe-1, this year.

"Following successful several crewed and robotic missions to the 8-5 tonne Tiangong-1 and Tiangong-2 testbed space labs, launched in 2011 and 2016 respectively, China has developed and constructed the core module for the planned Chinese Space Station, named Tianhe-1.
The Tianhe module, which in appearance resembles the International Space Station's Russian Zvezda Service Module, will be launched around 2019 by a new, Long March 5B launch vehicle, an as-yet-untested variant of the heavy-lift Long March 5 specially designed for lofting the 20 metric tonne space station modules to low Earth orbit."

China plans to have completed construction of their first space station by 2020.
