#351 Re: Human missions » First Space Mission with Amateurs. » 2021-09-20 14:33:16

I've suggested before the Biden administration is actively seeking to stymie Space X.

The tension is now out in the open. Musk has criticised "sleepy Joe" for failing to congratulate his company and people on this highly successful mission, the first of its kind, and a testimony to the US's continuing ability to make major technological advances, not least by attracting the brightest and best from all around the world (something China or Russia can never do).

Are people aware of this event?

I lost interest when I saw the guy from JPL enthusing about a proposed flyby (!) mission to Mars in 2033. I suppose they could  wave to the Space X people down below who will have been there for at least 5 years...  smile

The NASA budget has been something like $20 billion for many years now. I may be a few billion out...but it's a very substantial sum. It is clear from the example of Space X that NASA could have got to Mars 20 years ago or more with that sort of budget. But rather than focus on a few key projects, NASA has pursued a defuse approach which has spread the budget too thin. If we'd had a Mars base for 20 years all the money frittered on various probes could have been consolidated into the Mars project.

NASA is not fit for purpose which is why a long time I suggested it should have been split into firstly a Mars and Lunar Exploration Agency tasked with setting up human bases on those bodies and secondly a Space Science Agency which could pursue all the other 1001 projects that interest NASA scientists and bureaucrats.

The two agencies would have had far more impact than the single NASA.

I told y'all this administration will use regulatory obstruction to try and halt what will be a huge ideological defeat for a stunted unimaginative statist space policy.

That said, my current view is Musk is several moves ahead in this game, as always. Seems like they were nowhere near orbital launch capability a few weeks ago. A lot still remains to be done. But Space X have been applying the pressure early I think in the hope that any regulatory hurdles can be overcome before he achieves orbital launch capability. Felix has some good update info:

So much going on and needing to go on... I think we can rule out a September launch.

Of all the issues facing colonists this might well be the biggest. If you can't grow plants well in direct sunlight then that places some limitations on growth or means you might need nuclear power to grow food underground.

But I agree with you -  the game is not yet up. We need to see what mitigation measures can be put in place. It seems as though this scientist, like many is beginning from a certain position.

One thing I have wondered about is reflectors - are there reflective surfaces that absorb major radiation, or the bulk of it, but reflect the light spectrum that plants use to derive energy. If so you might be able to design greenhouses that make use of that phenomenon - being shielded above but having light reflected in and bounced around on mirrors at the sides.

I would agree that we might be looking at several decades of indoor, artificially light farming before workable solutions are found. 

SpaceNut wrote:

The use in space to mitigate exposure will be used and then some others for a mars greenhouse use.
Layers of water, heavy gasses, glaze coatings on the plastic or glass, static electricity or RF fields weak and strong magnetic fields ect.

Growing crops on Mars? Probably not under the naked sun

The radiation was emitted by five cobalt 60 sources, especially 'made' by the RID. The sources were placed above the plants to create a plane radiation field comparable to Mars. The growing plants were radiated constantly for 28 days and harvested afterwards. Creating a plane radiation field is tricky and that is why 5 sources were used to prevent one plant to receive a higher dose than another plant, which would otherwise influence the outcome of the experiment. We only used gamma radiation where on Mars cosmic radiation consists of alpha, beta gamma and UV radiation, so there are still differences, but the dose was about the same as what Mars receives.

https://insidescience.org/sites/default/files/2021-08/Mars-Plant-Illustration.jpg

Once Wamelink and his team secured radioactive cobalt, the team grew rye and garden cress in two groups: one with typical growing conditions and the other had similar conditions but added gamma radiation. Four weeks after germination, the scientists compared the two groups and saw that the leaves of the group exposed to gamma rays had abnormal shapes and colors. The weights of the plants also differed; the rye plants in the gamma-ray group weighed 48% less than the regular group, and the weight of the garden cress exposed to gamma rays was 32% lower than their unblasted counterparts. Wamelink suspects the weight difference is due to the gamma rays damaging the plants' proteins and DNA.

Can I point out a grammatical error in your post? Where you suggest "We are forward thinking, open, and progressive." I think you'll find that should be "We were forward thinking, open, and progressive."

When we look at some of the areas identified by Joe White as  potential building structures on Mars, it's worth reminding ourselves what 2000 year old structures on Earth look like.

Here's a video on  structures dating back to the time of Alexander the Great in central Asia:

https://www.youtube.com/watch?v=k0pddroJqt8

Imagine what the structure at 00:41 would loook like after 10,000 years or 50,000 years or 500,000.

Then think back to some of the structures dismissed as "butes".

Likewise at 12:58.  The structures atop the mountain really do remind me of the "city" on Mt Sharp identified by Joe White and others:

https://www.youtube.com/watch?v=FNSkuX0YtlQ

(Freeze the video on 00:18 for a look at what Joe White calls "The Forbidden City")

I really think we need to keep an open mind on all these anomalous finds. Many of these locations seem to be debris fields rather than natural rock fields. And I think there are way too many weird "rocks" that suggest machinery, living animals, statues and so on.

I accept we can't be sure either way until we get there and examine some of these places close up. But I think enough has been found for

There won't be poverty on Mars! a highly educated population with a huge GDP and vast energy resources, advanced robotics and all the rest. Poverty won't get a look in - unless we deliberately import it.

Musk has said, for what it's worth, he wants the colony to be run on democratic principles, with  a strong element of direct democracy.

Mars  for certainwould be a frontier planet, I guess there could be competition for resources, even poverty but at what cost would you have rule, totalitarian government or imperial space power to eliminate some gang boss or have some undesirable sentenced to death?

#366 Re: Not So Free Chat » California Wildfires » 2021-09-02 17:05:20

Good points! I am sure you are right it is not a case of drones v traditional fire trucks but more a case of getting a quick response started and then using all available resources.

Unsurprisingly, others have been thinking along similar lines.

https://www.youtube.com/watch?v=XNF_Sddlgy4

I just feel someone needs to bring it all together.  I'm surprised, given the extent of the problem, that there doesn't appear to be any serious NASA style co-ordinated effort to address the issue. The cost of wildfires in 2018 alone was over $90 billion in the USA. It's not as though this wouldn't pay for itself! If you invested $30 billion in developing the concept (I doubt it would cost that much, but hey...) you'd easily recoup that within 3 years minimum. 

I'm seriously wondering if there is institutional and ideological resistance to solving the problem. An absence of major wildfires would not feed into green climate change propaganda for sure.

Calliban wrote:

The drones don't necessarily need to extinguish the fire.  If they can pinpoint it rapidly and slow its rate of growth, then ground based forces with much greater capacity can move in.  Firefighting is often staged.  There is a first response, second response, etc.  The principle is to mount a rapid and continuous aggressive attack.  The more rapid the first response, the more successful the second response will be.  If a fire gets beyond a certain size, it will be beyond the capacity of a fire engine and hydrant to extinguish.

Fires tend to grow on a t-squared basis.  That is to say, heat output increases with the square of time since flaming ignition.  Some fires involving vertically stacked combustible materials will grow of a t-cubed basis.  For most fires, if the fire crew takes ten minutes to respond instead of five, then they will be facing a fire with four times the heat output.  That is a huge difference in severity.  If drones can pinpoint fires early, allowing fire crews to arrive just a few minutes earlier in the fire growth sequence, the difference in success rate will be quite dramatic.  If they can deploy water mist to reduce fire temperature and retard growth, better still.  Sometimes, small things can make a big difference, especially when severity is more than a linear function of time.

#367 Re: Not So Free Chat » California Wildfires » 2021-09-02 15:15:16

I would agree there is a role for ground robots as well. Maybe something like a Boston Dynamic robot dog that could be parachuted in by drone and could climb down from the canopy. Maybe robot dogs could be virtually fire proof and use fire blankets to suppress fire at ground level.

The automatic taxi drones that have flown in Dubai can carry two people - so I guess around 200 - 250 Kgs capacity. Let's say 0.25 ton. One hundred drones could pack 25 tons of water or fire suppressant. The water mist does sound a good idea.

https://www.youtube.com/watch?v=qArZGwtRINg

That might not seem a huge amount but on the plus side they could be very accurate in delivery, and could keep up a continuous operation working as a "team". The big aeroplanes and helicopters have to fly to a water source and then return. Drones could operate from nearby water trucks or special  water tanks. Maybe they could even deploy large fire blankets on trees, working in combination. I suspect drones could also work a lot better in smoke and at night.

I'd be surprised if we don't see these sorts of technologies come into play

#368 Re: Not So Free Chat » California Wildfires » 2021-09-02 05:38:25

One can argue about the causes of wildfires - AGW, arson, poor husbandry and over-development - and to what extent they are a natural phenomenon that has ecological positives.

But I am wondering why in the early 21st century we are still relying on fire trucks and big aeroplanes to fight fires.

The US military is developing "drone swarms" for combat.

Surely this is the way forward with fighting wildfires. In vulnerable areas you could have constant monitoring by drones (that automatically recharge their batteries from a central station) for "hotspots" showing the start of a fire. If a fire is confirmed, a drone swarm of larger drones carrying water or fire suppressant could be called in while the fire is still relatively small. A drone swarm would be beneficial from all sorts of angles: it can operate anywhere, in the remotest locations; unlike aeroplanes or helicopters dumping large water loads, it can keep up a constant uninterrupted sequence of fire suppression; it does not suffer from fatigue; and it can watch over the fire location for any re-ignition of the fire.

I find the "strange insect" highlighted in the first few minutes of the video very interesting. I've never seen a "rock" like that. The two delicate lines either side of the "body" are very suggestive of wings or similar.

If someone claims it is a rock, perhaps they can post an image of a similar rock from Earth.

The neighbouring "creature" also seems to have a body shape rather than being a rock .

I never used the phrase "step by step programming" so I don't know why you're suggesting I did.

I don't think you understand the concept. The key word in the article is algorithms. It's all algorithms = code.  Yes there's more subtle interaction between calculation points, but it's still all code. No "neural" network would work without code.

I think the economics of 3D printing may well stack up on Mars. You won't have to import the mass which might cost say $100 for a steak. You won't have to use artificial light or build expensive pressurised pastures in order to produce the meat.

The meat might be nominally more expensive than one on Earth, but the Mars economy will be a hi tech and very productive economy. 3D printing of meat will fit perfectly.

That said I have read that stem cell muscle tissue doesn't taste anything like real muscle tissue on cattle. Basically you have to exercise the tissue as happens in the real world and I believe some companies were working on that (creating little "muscle gyms" to work out the tissue - I kid you not).

#372 Re: Not So Free Chat » How far to the abundance economy? » 2021-08-30 13:40:59

A lot of hubris in your post.

Chinese culture has an entirely different approach I think. First off they see themselves as cultural superior and at the centre of affairs on our planet. For them the existence of an independent Taiwan is something that goes against nature and has to be rectified. It's just as much an idea as was the US Constitution (I use the past tense advisedly).

It's a mistake to say their system has become capitalistic. It has strong elements of capitalism but it's probably better thought of as planned state capitalism. The Chinese have a plan to march through all economic sectors and become the leading provider. So far, thanks to Western indolence, political corruption and idiocy, they have been allowed to get on with their plan. Trump is the only Western politician to have stood up to them, and he was removed in a political coup aided and abetted by the Chinese regime.

tahanson43206,

It's not that China doesn't have the potential to be a great nation, but communists focus on people.  Only small minds do that.  Great minds focus on ideas.  Their system of governance is a failed retread of an idea that was a failure from its inception, that has succeeded in bringing about prosperity nowhere on planet Earth, for so long as people have attempted to implement it.  The only reason China still exists as a nation is their adoption of capitalist economics principles, because had they continued on with communist economics principles, China would've greatly resembled sub-Saharan Africa.

Apart from that, as Peter Zeihan noted, China is an old folks home with a terminal demography.  25 years after their government's 1 child policy, it takes another 25 years to produce a new batch of 25 year olds.  Their children will be taking care of the vast sea of elderly people now, else that impressive population stat will cease to exist inside of 10 years, although that may be inevitable now.  Half the population there is near or over the age of 50.  Look at the crude birth and death rate per 1,000 for their 2020 census.  In the next 10 years, their population growth rate will be negative, since well over 50% of their population will be at or near retirement age, and the other 700 million will either be making robots like mad to take care of mom and dad so they can work, or that population stat will be half of the number of people in India 20 years from now.  The same is true of Russia nowadays.  They're more of a threat to themselves than anyone else.

China's continued existence is now predicated on exports to foreign countries, because if they stop doing that then their wealth evaporates, both their national economy and military atrophies into uselessness, and they basically go back to living the way they did before they adopted capitalism.  The Chinese people send their money abroad, especially to the US, because they realize that they're only one more currency manipulation away from financial ruin if they reinvest into their own country.

Controlled chaos is normalcy over here in America, especially for our military.  We wrote the manual on modern military operations, but never read it, because we've been at war for so long now that constant fighting is all we've ever known.  Remember that Russian special forces gaggle that tried to attack a Marine artillery unit in Syria?  That didn't go so well for them, did it?  Everyone else, including our allies, freaks the hell out whenever things are the least bit chaotic, from their own point of view.  The only form of stability that America has ever had, has been constant change, which is what we thrive on.  Whenever we begin to stagnate, then we're really screwed, but nothing of the sort has happened since the founding of this nation.  Nobody who has bet against America has ever left the game with their shirt on their back, so it's probably not a good idea to re-test that theory after 200 years of history all running in one direction.

Not relying upon centralized authority is why America can be presided over by a senile old man surrounded by evil clowns, but nothing materially changes.  There's no real power invested in that person, because our founders were so very wary of one person having unlimited authority.

One thing's for sure though, and that's that nobody is desperate clamoring to get into communist China.  In contrast, everybody and their dog still wants to come to America, because we still do new ideas and big ideas, such as taking humanity to Mars.  If our system of chaos were ever to befall China, there would be a revolution in a heartbeat, because that's how much the people living over there detest their living conditions.  We worry about cheeseburgers being $1 or $1.50.  They worry about importing enough pork and chicken and legumes to prevent millions of their people from starving to death.  That's a pretty stark contrast.  We still import oil because part of our national strategy is to consume everyone else's oil first.  None of our food is imported, except by choice, to provide an even more bewildering array of meaningless choices to people who can't figure out that they're being terrorized by a bunch of evil clowns hiding behind the dark curtain.  My old boss, a Canadian man living in America, told me you know that you're successful when you can have a bunch of idiots working for you, but still manage to make money hand-over-fist.

Are things any less desperate for some people in America?  No, but people here wear their troubles as a badge of honor, rather than a mark of hopelessness.  I wouldn't trade any of the economic, health, or other issues I muddled my way through as a young man.  It's how I became who I am, and I don't look down on those experiences, because they were necessary.  How can you know what success looks like if you never experience a failure?  Moreover, how can you ever learn and grow without failure?  That's the part that zips right over the heads of people living in societies like communist China.  Rather than putting the brush down after painting themselves into a corner, they keep hoping that someone else will come along to remove them from their corner.  The only people who can do that are them.  That's what they still don't get.  That is why people still come to America.  Those are the people who realize that it's time to put down that stupid brush.  The ones they left behind will never "get it".  If they did, then people would no longer feel the need to come here.

China's fixated on taking a piddly little island off their coastline, filled with their fellow Chinese people, as if that will change the situation they've created for themselves.  That is akin to America worrying about how to take over Cuba or Haiti (who for all intents and purposes may as well be Americans)- because that would solve our problems, right?  Meanwhile, entrepreneurs in America are well on their way to figuring out how to take over an entire planet tens of millions of miles from home.  Just think about that for a moment.  A nation with more than triple our population wants to invade Alcatraz while the richest men and women in America want to invade an entire planet... to both provide a second home for humanity and, as always, to make that next almighty dollar.  If that's what China is betting the farm on, then yeah, I'm still betting on America, because the alternative is pure idiocy.

Thanks for the explanation.

I have never believed computers, even the most advanced, can "think" for themselves. They aren't conscious. As John Searle, the philosopher, reminded us long ago now with his "Chinese code" theory.

But they can be provided with enough coding to make decisions independently of human beings (or situation-specific code) and yet make good decisions. This is precisely what a driverless car does. The car's computer is combining codes to make decisions, but without situation-specific code. Perhaps you agree in your comments about decision points.

The thing about the decision points is that the computer can store decisions and their outcomes and make decisions about whether they would repeat or modify their actions, given the outcomes.

SpaceNut wrote:

A computer program does not think for itself it continues step by step through code until it gets to the next decision point in the coding.

Breaking the code means that it must come up with its own decision point which makes it think as its no longer just moving step by step with in the coding instruction.

That makes no sense unless you want to explain.

Musk's essential point is that AI is an independent force from humans...unless humans actively constrain it in many, many ways it will be independent of us and do things it wants to do, not things we want it to do.
