a clean-sheet rocket would be preferable with superior flexability and less sketchy probable costs.
Yes and the puts the total responsibility for crew loss with the company that would build it. Since none have manned vehicles now or in the past other than the joint venture of the shuttle. One can only feel that they do not want that responsibility otherwise IMO they would have already built a man rated unit and we would not be talking about SDV or of needing a CEV.

Welcome to newmars Manchu4: Like yourself I too am no scientist, and have followed all events of space.
Having watched the old black and white tv images of the lunar landings and more. I to feel that the robotic probes have down a fantastic job but at some time it is mans turn to go and to make his presence on other surfaces in space beyound Earth known.

Nasa is still pushing forward for the schedueled flight of which they still have not chosen which repair techniques will be carried on the first flight for a repair demonstration in space of columbia style damage.
NASA Still Debating Space Shuttle In-Flight Repairs
NASA is still undecided about which techniques for in-flight repair on the heat shield to test to ensure the Columbia accident is not repeated.
MIXING MATERIAL IN SPACE
The heat shield repair technique that spacewalkers Soichi Noguchi of Japan and Steve Robinson have practiced the most involves a complex caulk gun and a heat-resistant material known as STA-54. Ground tests, however, indicate there may be problems mixing and applying the material in the weightless environment of space.

Weapons of any form should not be tolerated in space but here is a space trek enterprise not really a weapon but a means to get there. ‘Beam me up, general!’ Could ‘Star Trek’ technology help transport troops?
Feb. 9: The Air Force recently spent $25,000 investigating whether it might be possible to "energize" someone across long distances, as in "Star Trek." Is it money well spent? NBC's Tom Costello examines.

Russia reveals possible Soyuz replacement
Published: 2004 Feb. 25
For many years, Russian engineers pondered over possible configurations of a new spacecraft, which could replace venerable but small Soyuz. In the course of its history, RKK Energia, the Soyuz developer, attempted to tackle the issue several times, however financial problems of the Russian space program kept preventing the fruition of these efforts.
During the press-conference at the ITAR TASS news agency on February 17, 2004, Yuri Koptev revealed that RKK Energia, the developer of the Soyuz, was working on the brand-new vehicle called Kliper since 2000. In the following days, a flurry of reports in the Russian press provided first details on the project.

Getting the average joe interested in space is a first step in getting the funding for the vision. Even if that interest is only for now sub orbital, it at least an interest.
Caught a glimpse of this commercial:
Space Race 2: Spaceflight Ad Hits TV
Volvo's sweepstakes rules stipulate that if regularly scheduled commercial flights into sub-orbital space have not begun by March 1, 2009, the ticket to ride, along with up to $100,000 in cash to pay for federal and state taxes on the prize, will be rescinded.
Instead, the winner will receive a cash substitute in the amount of $100,000 - enough to buy a pair of Volvo's new luxury SUVs.

Well it was only a little while ago that I had synically proposed letting the military shot it down.
Article from the TheSpoof.com, hee hee
Bush Orders Army to Shoot Down NASA’s Hubble Telescope. "Hooah!"
“We hit that sucker with the 2nd round. Hooah!” exclaimed a young lieutenant from Bravo Battery. “Sure beats the livin' crap out of firing blanks all day long!” Pieces of the Hubble Telescope soon began falling from orbit over a three state area. A large fragment fell on Bill Clinton’s boyhood home in Arkansas. Bush administration officials were quick to deny that this was planned. A smaller fragment hit an outhouse in Mississippi causing minor injury to a sharecropper and interrupting his morning duties.
Some would love it if this were for real 
#28609 Re: Terraformation » NASA plan to heat up Mars? - Guardian article » 2005-02-09 14:48:53
Understanding of how to warm Mars up and how sensitive it is to induced changes can be studied here on Earth before attempting to change Mars.
Climate: The Sensitivity Question
The measurement, called climate sensitivity, indicates how surface temperatures respond depending on how much greenhouse gas is pumped into the atmosphere by humans. The usual measurement baseline is a doubling of CO2.

A Spiral Stairway to the Moon and Beyond
Replanting boot prints on the Moon. Hurling expeditionary crews to distant and dusty Mars and other destinations. Executing a 21st century outreach campaign to faraway worlds demands a safe, sustainable, and affordable transport vehicle system.
Though the CEV’s main purpose would be to leave Earth orbit, the vehicle is also assigned the duty to ferry astronauts to and from the International Space Station after the space shuttle is phased out. The CEV or versions of the CEV could operate for extended-duration in Earth orbit, as well as in close proximity to or on the surface of the Moon and Mars.
The first spiral development planned for Constellation Systems is scripted to deliver humans to Earth orbit in a CEV by 2014. The second spiral will dispatch humans to the lunar surface no later than 2020, followed by the third spiral that will enable extended visits to the Moon’s cratered landscape
In 2008, the selected contractors will carry out unpiloted "boilerplate" CEV trial runs. The CEV program calls for a boilerplate type test in 2008, to look at various risk areas.
Congress is sensitive to cost overruns and delays as seen on past large space projects. "So as we move forward, we need to have some discreet victories on cost and schedule…like the 2008 CEV demo. Congress wants to see NASA reduce the schedule and cost risk of the standard prime approach by including a nontraditional company that uses rapid prototyping techniques and lean staffing.

Dryden losing jobs, funds: Bush's spending plan calls for reductions
NASA Dryden Flight Research Center will see its budget cut and its work force reduced in 2006, but the center's director said Tuesday he feels confident additional work can be brought in.
Under the president's proposed 2006 budget, Dryden will see its civil service work force reduced from 568 people to 527. Dryden Director Kevin Petersen said he believe the reductions will be achieved through voluntarily means, such as early retirements and inter-agency transfers.The center's baseline budget will also be cut from $160 million to $130 million over the next two years.

An ugly grind: NASA's budget shows how tough it will be to transform the agency for moon-Mars
As NASA heads in earnest toward its moon-Mars mission, Brevard County and space advocates nationwide had better strap themselves in tight for one tough ride.
The agency's 2006 budget, unveiled Monday by the Bush administration, shows the difficult road ahead as priorities are set on refocusing NASA to met it's new goal.
While there's immediate good news -- NASA's proposed $16.5 billion budget is a small increase, and represents a win compared to steep cuts the White House wants in other programs -- the big picture is harsh.
The articles opinion is that Nasa needs to change and that some of what it has already started into motion will in the long help it come around to make possible the grand dream of the moon, mars and beyound .

On the issue of the UN since it is in America and we have the largest force available to call on, we have set our selves up to be the police force of the world. I agree that sometimes the UN votes against us just to hinder the US from being more dominate at times. But IMO we have no need to conquer and hold any lands where we go into on the UN or those that live there's behalf.

Good day Mr. dicktice you pose a good question on the effects and response to radiation.
I guess the issue with radiation and cataracts developing is one of how soon after exposure does one get them and who would preform the implant operation in space if such should occur.
Then on the biological repair process, what can be done once repair process has been started to minimize reoccurance and risk of cancer due to continued damage.
#28616 Re: Human missions » Hubble Mistake **2** - Action still Needed » 2005-02-08 22:56:15
Over the past year I have discussed these and many other issues with the director of the Hubble and it is Nasa that has the problem of flying it the way that it is. It is of little consequence that most if not all former astronauts would fly such a mission to the Hubble with the shuttle.
Now why can a combination of a progress and a soyuz ship not be used to do the Hubble repair if launched from a site closer to the equator. Or even an Arriane, soyuz combo.

On the note of need for some sort of shield and for the need to create artificial gravity. I think making a craft something like a motor fits both items.

Not really you basically end up with a delta rocket but just of different dimensions with rather than 3 identical first stages strapped side by side you get 2 srbs for 2 of them around a new core. Take away or add segments as needed for bulk of lift. External tank would also change in size and shape with same boeing rs68 engines. Not really a clean sheet design but close.
#28623 Re: Human missions » Hubble Mistake **2** - Action still Needed » 2005-02-08 07:29:08
While there is still alot of effort for and against funding any activity for deorbit as well as repair. There still continues the effort to prolongs its useful life.
NASA plans to spend $93 million to develop ways to prolong Hubble's life by sending commands from Earth, and to bring it safely into the ocean when it dies.
Two Boulder-built, next-generation Hubble science instruments with a combined price tag of $170 million are awaiting installation on the telescope.
Ball Aerospace & Technologies also built Wide Field Camera 3, the other instrument awaiting installation.

Here is another article talking to the Brown dwarf may someday harbour habitable planets
The construction site of a miniature solar system has been spotted but, unusually, its central star is a tiny brown dwarf. The star is so small it could be mistaken for a giant planet and it is surrounded by a disc of material chunky enough to form several planets the size of Earth or Mars.
Brown dwarfs are "failed" stars with masses of about 15 to 70 times that of Jupiter. They are thought to form like ordinary stars, from a collapsing cloud of gas and dust. But unlike ordinary stars, they do not generate enough heat to trigger the sustained nuclear fusion of hydrogen nuclei that makes stars burn bright.
What are the closest brown draft stars to us? Could there be other earths near by?
#28625 Re: Interplanetary transportation » Just Cancel The Shuttle Program - Not in five years, do it right now. » 2005-02-08 06:06:21
Well in the news due to the coming years budget there are slated a number of facilities job losses and attempts at reducing the number of shuttle flights remaining to complete the station. Seems like a lot of numbers are being rearranged in order to free up the cash to construct the CEV on a faster track IMO.
Cuts target shuttles, defense; Proposed $16.5B budget signals end of orbiter era, dooms Hubble
phasing out spending on the shuttles and cutting other projects to free billions of dollars for a new spaceship as well as missions to the moon and Mars.
also cut funding for a mission to rescue the ailing Hubble Space the ailing Hubble Space Telescope and pushed back or eliminated money for some big-ticket science missions and aeronautics research.
Gaining less notice: $160 million included to buy cargo and crew delivery services from other countries or private companies. The idea: Shift supply runs from the shuttle to less-expensive space freighters and station crew changeovers to the Russians' Soyuz, which has done the job while the U.S. fleet was grounded the past two years.
