Russian Resupply Crash Could Mean Leaving ISS Empty
astroengine writes "In the wake of the Russian Progress vehicle crash shortly after launch on Aug. 24, a chain of events has been set into motion that could result in the decision not to fly astronauts into orbit. If this happens, the ISS will be temporarily mothballed before the end of the year to avoid landing astronauts during the harsh Kazakh winter."
Oh if only some other nation had something spaceworthy... Like a shuttle or so...
Once a government project is mothballed, it becomes VERY difficult to get it going again.
If it happens don't expect the ISS to remain in orbit very long.
The ISS, and manned spaceflight in general, is a pointless waste of money. Not a troll, just a (well-justified) opinion.
Would you care to share this justification? I am quite curious.

In the face of money spent on financial disasters and wars your comment seems a bit less then "well-justified".
So basically, you're saying that spreading away from a ball on which humanity would otherwise forever be trapped is a total waste of money?
Ensuring the continuity of life on Earth is a waste of money?

Where will our technology come from now?! We MUST establish a presence in our atmoshpere's low orbit to prove to the aliens we're smart!!!! This is VITAL STUFF!
Waste of money? Is living out a meaningless existence without exploring our universe enough for you? What's the point of our civilization then? Are we seriously to sit here on earth and never even try to push the boundaries of what we're capable of?
Spreading to where? Last I checked there were no M-class planets nearby.
You are not your species.
And the era of human spacetravel came to an end. Not from discovery or war or any disaster. But simple greed. Greed that says using our resources to take what others have or wasting those resources for entertainment are more important than the spread of the species.
Trapping us all on this tiny blue planet until the inevitable end comes.
So we wait for the next global disaster to wipe us all out in one swipe. Be it a germ, comet, meteor, pole shift, solar flare, gamma burst, supervolcano or the unwise use of technology itself.
Perhaps if another species arises on this planet it will be a little more intelligent and not keep all their stuff in one place.
It's ok tho. It seems to be a common mistake given the emptiness of the universe. So don't sweat it too much. Go have a beer and some fast food, sit down and watch tv. That's whats important after all.
"Nearby" is a relative term. Your statement would seem to indicate that developing our space travel capabilities is not just a good idea, but ultimately necessary.
Spreading to M-class planets that are far away, duh.
I disagree. Manned spaceflight, true, should be superseded by space colonization. With a booming population, and declining natural resources, mankind has outgrown our native earth. We desperately need to get out there. What we need to stop, though, is considering space only the preserve of scientific experiment. We need to really go there. It's the only growth allowed us from now on (economic or otherwise). It will never be the uncontrolled growth of a human population apparently infinitely smaller than its home world allowed it to think was possible, but the only outlet left. It is psychologically important for a species that grew up in a conceptual and instinctive framework calling for growth.
The space program is one of the most important pieces for a constructive future. Of course, more of it should be targeted towards building permanent settlements and industry in space and extraterrestrial planetary bodies.
well the old shuttle was getting old and the newer spaceX stuff is now ready yet also Constellation was not going to be ready by 2011 any ways. If not for the Columbia disaster we may still be useing the shuttles to day.
According to a prior slashdot article, SpaceX is slated for another demonstration launch late November, this time docking with the ISS. Yes, it is a demo flight so, yes, you can't trust it to succeed. Still, is there any reason they cant load up the Dragon capsule with [critically required items]?
You cannot justify a bad investment by point to an even worse investment. I cannot comment on the ISS and whether the money is well spent... but your comparison is invalid.
Russia has had fewer astronaut fatailities than the United States, and all of the fatalities Russia has had have been less recent than any of the US's fatalities (those occurring in space, not on the ground). Although it would certainly be a tragedy if people died on a Russian spacecraft, please remember that the reason we now rely on Russian spacecraft is because people died on American spacecraft, and NASA responded by retiring all of the spacecraft involved in the human space program (without developing replacements).
Is it a requirement that they land their ships where they do? Couldn't they, at least as a limited emergency measure, land them in a more temperate climate? I'm sure the United States would be happy to provide whatever assistance needed to land them at some appropriate location here (assuming there isn't a more reasonable location in Europe or Asia).
Just dunk the damn thing.. Wall Street isn't interested anyway.
For justice, we must go to Don Corleone
If you want to spread humanity to another planet you better invest in automatic probes that can survive a few hundreds of years long trip and that can bread and educate some new humans on arrival. Sending live humans through interstellar space isn't going to work anytime soon and even if it one day would, it would be a waste of money.
And yet, you offer nothing of substance for your opinion, while the facts of manned spaceflight does. You ARE a troll.
I prefer the "u" in honour as it seems to be missing these days.
can we have some dramatic music to this article please?
it was only a rocket that failed.. they did not start 2 pointless wars so they had to cancel their whole space program...
the russians are doing a great job and will get your shit up there...
You're stuck on Earth. You're never, ever, going to live on some other planet. It will never happen. You will probably never even live on the Moon. If somebody ever does live on the moon, it's going to be very exclusive and very tight. The Jetsons won't be over for supper. Your life is never going to resemble Lost In Space. Give it up, already. And as for this space station, how irresponsible can people get? America invested so much in this thing and we've basically tipped our hat and stepped out. Now we're not even capable of keeping the thing in orbit because we've scrapped our shuttle program. What are you going to do, space cadets? You planning anything amazing for us? Maybe pulling all your space cadet sticks out of your asses, duct taping them end to end and propping the ISS up that way? And now look, Russia was so hype to step up to the plate because, as you noticed, the ownership of the ISS defaults to Russia if America isn't capable of upkeep. Yet even they can't manage to resupply. Who's it going to default to, now? Buck Rodgers?
It's a fiasco, and all you butt-hurt sci-fi bookworms are to blame. We don't NEED an ISS, we don't NEED space programs, at all, any of us, anywhere, for anything. You're never going to live on Mars. Your responsibilities and your life's consequences here on Earth are real things, not imaginary. Space is never going to be a place to escape to no matter how much money you throw at it.
Tonight: go outside, close your eyes, count backwards from ten, and when you open them I want you to look up at the dark night sky and believe it's nothing but a giant black hole and it's worthless, it's a waste of time and money and the stars might be pretty and all but they aren't full of friends and adventure.
Now grow up.

We're all cosmonauts now, comrade.
He didn't state support for Iraq or the financial bailout.
First, please note that this is not about supplying the ISS, it's about getting the crew there. NASA is worried about the safety of Soyuz.
Also, note that the flight of the Soyuz is not dependent on NASA. NASA doesn't get that call, although they could yank their astronauts from the vehicle, they can't ground it.
So, there is little to no chance that the ISS will be abandoned. I predict the Russians will keep a crew there, regardless of NASA's decision.
The question is whether putting humans in space is the best way to go about this - robotic probes can be much more capable than manned craft for a given price. If we are going to colonize something, we need better propulsion, more knowledge about the destination, etc. There will be no friendly natives to help feed starving colonists this time around, but if we can develop robotic means of producing food and shelter in advance of human arrival, we can create a suitable substitute. I don't know the merits of colonizing the Moon, Mars, or one of the moons in the outer system, but before we send humans there, we need a way to produce the food and energy they will need. Until we create that infrastructure, colonization remains a pipe dream.
This guy put it very succinctly.
Right now, we Americans are money grubbing war mongering bullying little people who cling to past greatness like a middle aged ex-high school football star who thinks we still "got it".
We hear and approve of people who continue with our illusions of greatness and "American exceptionalism" and think that if we just believe the right way, everything will work out. Unfortunately, belief alone doesn't do anything - you have to do.
We've lost our ability to dream, to do, and to accomplish.
Remove bloated federal government, which WASTES more money than anything, and watch space flight/travel take off...so to speak.
The "government" produces NOTHING.

Your comment and others like it remind me of some wisdom gleaned from xkcd:

Right now, our grasp of space exploration is still quite limited. In my opinion, the state of space exploration today is to its potential as alchemy was to modern chemistry. Nonetheless, alchemy represented the first baby steps toward real chemistry. I think that a lot of people recognize this and look at space exploration with the same disdain that they would an institute of alchemy. They key difference is that we don't do alchemy anymore because we outgrew it as it evolved into modern chemistry. Space exploration hasn't evolved into something useful and profitable yet but if we don't keep at it, it never will. (Note, I'm NOT equating space exploration with the ability to merely put things into orbit.)

Note that if the station is left unmanned, it will be the end of an 11-year run of humans continuously in space, starting with the October, 2000 arrival of the Expedition 1 crew at ISS.
By the way, the Chinese are still flying their man-rated Long March.
Humans need life support, robot do not.
I do not agree with the GP, but this is the usual reason.
If we are going to colonize a new planet at some point we will need to know how to get humans to this new planet. Practicing in earth orbit for how to keep humans alive and healthy in low || 0 G environments is useful science. About the only way i can see to test long term effects is to actually do the tests in a real low G environment with real people.

There is nothing wrong with space exploration, in fact that is what we should do more of, but space exploration doesn't need humans, humans are nothing more then ballast that increases the cost and troubles. Just look at how far we have come. Human exploration has brought us to the moon, robotics probes on the other side are already flying outside the solar system.
. Practicing in earth orbit for how to keep humans alive and healthy in low || 0 G environments is useful science. About the only way i can see to test long term effects is to actually do the tests in a real low G environment with real people.
0G = bad stuff. If we were really interested in colonization and establishing a presence in space, we would have built a spinning space station with artificial gravity. That's the only way we'll be able to endure long stays in space.
Actually you can. That's how you fix things. You have two bills to pay, a $5000 bill costing you 30% interest per year, or a $2000 bill costing you 2% interest per year. You have limited funds. Which bill do you pay off first...
While the above was an analogy, in the case of government (mis)spending, which program do you cancel/fix first?

"Class M" is a fictional Star Trek term. I think what you meant to say is that there are no nearby planets in the habitable zone.
Some of what I say is fact, some is conjecture, the rest I'm just blowing out my ass...you guess.
What's the point of our civilization then?
Who said there has to be a point? Look at my dog, curled up by my feet. She's happy, and she doesn't worry about her life having some sort of point. She lives for the moment and enjoys every day of her life. And one day she'll drop dead. We all will. And then what was the point, if you spent your whole life worrying about things you can't fix? Take care of the stuff you CAN fix. Just wishing the stars to be closer will not bring them closer. And I'm too old to believe in magic anymore. You would need magic to be able to 1) find and 2) reach a habitable world within the lifetime of the human race. And when you got there you would just fuck it up like we've fucked this one up.

Mars is in the habitable zone. So is Venus. And seriously, is there anyone on this forum who doesn't know what Class M means?
What's to stop the Chinese from boarding and effectively taking over an unmanned ISS? What could we do about it?
>Who said there has to be a point?
This is one of the most insightful things I've read in a long time.
So many people are worried about their existence having a "point". We need to relax and enjoy life a bit more.
The third stage shut down cleanly. There would have been no problem separating the spaceship from the rocket, then separating the service module and habitation module from the capsule ... and the rest is standard maneuvers.
The capsule is aerodynamically stable, so they'd only have to wait for it to come back down and open the parachute. It would have been cold in Siberia, true - but they wouldn't be dead. Unlike people in a fragile Space Shuttle with no means to escape or airport to land.
I hear Somalia and Afghanistan will be launching their 100% infidel-free capsule any millennium now.
Dunbal-"Actually you can." (... justify a bad investment by point to an even worse investment.) By bad investment he might have meant an investment with a negative overall outcome, which really shouldn't happen at all. How about something that actually isn't bad investment at all then? Like an investment into the search for alternative energy sources? Through the global economy it would make even the space flight cheaper, not to mention that it would also solve many other problems, like the next big problem - material production crisis (think about bauxite or silicon for example) and give rise to a new economic fluctuation (so that some "economic geniuses" could throw away their "communists were actually right about capitalism" thesis and concentrate on another stupid theory far from reality). Ok , now I went a bit off topic, but I am not going to delete it either. Thank you.

It's likely that "Class M" is more widely recognized than the scientific term "habitable zone". Even on Slashdot.

Let's face it, people aren't very good for survival in space.

we don't live long enough to get anywhere in one lifetime at attainable speeds
Space is just irrevocably hostile to human life as we are now.
If we weren't meat-bags anymore, but rather something more durable, say, solid state based on silicon, we'd be way better adapted for space. Yes, we'll be very different, but the galaxy will be ours.

Without a constant acceleration in spinning, If there is no gravity I kind of fail to see how spinning relative to objects that have little to no effects on the ship would have any useful effect.
Think from the frame of reference of the ship, it is stationary and everything else is spinning around it (without effect on it)... how does that make artificial gravity?
(shrug)
We get the future we deserve.
If that means eventually being wiped out due to our own shortsightedness or because we refuse to start things because it would take too long and be too expensive.
Well. Darwin approves.

This is not a true example of small government, rather an emotional argument.
Afghanistan was a pretty nice place before civil war and invasion destroyed it in the 70s or so.
where have those NASA safety people been for the past 20 years? we lost 14+ astronauts because of those clowns, now they are telling us the Russians are unsafe?
A spinning space ship to make artificial gravity for humans is a tricky and very expensive task. It would probably need to be much larger than the one in the movie 2001. There are issues of motion sickness etc that would need to be worked out
However, General Relativity states that a spinning system can be the same as gravity. It is the constant change in direction that does the trick. The same as centrifuges here on Earth work.
I think both of those points are obvious, and we were just being Romanticist, mildly off-topic dreamers.
Bio questions? Ask me to start a Q&A journal. Computer analogies available for most topics!
Spinning is an acceleration, dumbass.
I haven't noticed the Chinese scaling back. Granted, they're not as far along.
I think they still count as part of humanity, so human space travel wouldn't come to an end even if both the US and Russians stopped.
I don't like the possibility of mothballing at all but I think you're being a little breathless.
The one owed to the creditor with the biggest, numerous and most violent goons.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Space X has yet to put a man into space. Period.
Keep that in mind before saying how "useless" "overfunded" "wasteful" the NASA Shuttle and Constellation programs were.
well the old shuttle was getting old and the newer spaceX stuff is now ready yet also Constellation was not going to be ready by 2011 any ways. If not for the Columbia disaster we may still be useing the shuttles to day.
Correction, the Constellation program wasn't really going to be ready until 2015 at the earliest, and the more realistic projection was that it wouldn't be ready until 2020. There was a wish that perhaps the Ares I might have been ready this year (2011) when it was originally proposed, but there were a number of engineering issues that came up in part because they had an extended number of sections in the solid rocket stack where vibrations from the rocket would make the vehicle unusable for any astronauts riding it. The solution was to increase the weight of the capsule and add some heavy duty shock absorbers to make the ride easier for somebody on the vehicle. This vibration issue also impacted any unmanned applications of the rocket as well.
The fate of the Shuttle was pretty much sealed when production of new orbiters was halted. The Endeavor was really a test article (as was Challenger) which was refurbished to bring it up to flight status. With the loss of the Challenger, the handwriting for the end of the Shuttle program should have been apparent to anybody and many of the envisioned applications of the Shuttle simply never happened. All that the loss of the Columbia did was to speed up the end and drive the point home that the loss of the Challenger wasn't a one time fluke. We got lucky we didn't lose another orbiter before the program was finally terminated.
There is a simple solution to this problem. Launch another Soyuz rocket with another Progress module. Save the soul-searching and blame-finding for later. Sure, find out what went wrong and fix it. But do that after you have satisfied the customer.
Now, apparently Russia and NASA aren't going to do the simple route. But what's more important? Working the bugs out of a launch system or keep the primary customer, a space station with a multi-billion dollar replacement cost from splashing?
To create a spin-gravity generating station, without people getting sick from the motion, would require this station to be HUGE. Huge. Let's assume a station that rotates once per minute. I wouldn't speed it up much more, also 'cause people tend to be a wee bit uneasy if their own size of maybe 6 feet already means a considerable difference in gravity between their head and their toes. For more fun and to find out how it works, check out the Spin gravity calculator.
In a nutshell, if you can't built a space station half a mile in diameter, don't even bother thinking about it.

In my opinion, the state of space exploration today is to its potential as alchemy was to modern chemistry.
That's a good analogy. Alchemists were obsessed with turning lead into gold. Space nutters are obsessed with having humans colonize space.
As it turns out, both goals are technically possible, but neither is worth the effort with any foreseeable human technology. Chemists figured that out long ago and applied their knowledge to other, more useful, problems. NASA should likewise dump human space flight.
If and when transmutation of elements becomes cheap and easy, we can revisit creating gold for profit. Likewise, AFTER we have developed a feasible interstellar propulsion system, THEN we can start hiring astronauts.
Meanwhile, if you're worried about human extinction due to bad things happening on earth, you could get very effective insurance against that by building and staffing a dozen or so Dr. Strangelove style underground bunkers. This probably could be achieved within a few short years at well under $100 billion cost. However, it's not sexy enough for the space nutters, so they'll keep pushing for a Mars colony that would probably not be truly self sufficient for centuries.
Seriously dude? Did you drop out before middle school science?
I realize slashdot might not be the best place to post this, but there is an elephant in the room. The space station has cost a huge pile of money and has provided little more than a presence in space. No missions to mars or the moon have been launched from the space station as science fiction writers of the 50s envisioned. It has been an expensive and mostly pointless exercise. We did learn a few things about how hard it is to maintain a space station, and we did improve the technology for supporting a space station, but the external benefits are hard to see. So, maybe ending the ISS is a good thing. We can use the cash (that we don't actually have anyway) here on earth for maintaining some of our crumbling infrastructure. Maybe in a few decades we can think of a new good reason to put up a new space station. OK, let me have it. Really, what is so great about the ISS?

Wow, there is a lot of twisted logic on slashdot, but you win.
Actually, planning WAS done. NASA tried to get private space going back in the 90's, but neo-cons killed it. Thankfully, Griffin got it going as a backup to constellation. He was right on the money on this one. And again, thankfully, Bolde/Obama have fought against the neo-cons that have been working hard to kill private space. And Bolden pushed hard to get the last extra shuttle to provides supplies. That was fought by the neo-cons. Well, this proves that it was wisely thought out. SpaceX is about to get their launching orders. However, I think that a new progress will launch in about 1 month or so. And then you have ATV and HTV coming.
I prefer the "u" in honour as it seems to be missing these days.

Larry Niven made a better point: "The dinosaurs are extinct because they didn't have a space program." That doesn't require as much forward-thinking -- space colonization is a *long* way off, but meteor defense is a bit more immediate.
That said, private companies like SpaceX seem to be doing a better job at creating launchers than NASA was, largely because any NASA effort has to also be a corporate welfare program for established aerospace companies. I think we're better off letting NASA develop exploration vehicles and science payloads, and let private industry handle the trucking.

They are sending up our astronauts. We are paying them enough money. Surely if they land in Florida we can ship their landing vehicle back to them. We are not talking regular landings, we are talking about an emergency during harsh weather conditions.
Because our current engine tech sucks the big wet titty? look at how much we have learned and gained from the bots, we have had or are going to have orbiters around just about every interesting place in the solar system, learning more and more about how everything from gravity to solar winds work, all for about 1/20th the cost of our LEO crapola.
The simple fact is "Meatbags is SPAAAAACE!" simply isn't feasible ATM. We blew the endless cash on Apollo as a dick waving exercise against the Ruskies but frankly we could have gotten a hell of a lot more done with long term probes than by having astronauts hitting golf balls off the moon. We can experiment with new engine designs on the bots, no need for huge inquiries or shutting down the whole program if one blows the fuck up either.
We can simply get more done with less cost by leaving the meatbags on the ground. The bots don't need, food, water, man rating, shitters, air, extra protection for our fragile little bodies, its just stupid to waste limited resources on "Meatbags in SPAAACE!" right now, and this is from someone who loved Star trek and Buck Rogers as a kid. But I'm also a realist and our tech really isn't there yet to make meatbags a practicality.
Personally if it were me I'd stick with probes and look at reviving Gerald Bull's idea of a space cannon to cut down on the costs of moving material into LEO. From there parts could be assembled by robots to build larger and more powerful probes that could give us even more knowledge of the solar system so that when we DO stumble over the engine tech to get us out there everything will be all mapped out and ready for us. but now it is just a waste IMHO.

In a nutshell, if you can't built a space station half a mile in diameter, don't even bother thinking about it.
Cool page, but it doesn't really agree with you. Note its quote:
In brief, at 1.0 rpm even highly susceptible subjects were symptom-free, or nearly so. At 3.0 rpm subjects experienced symptoms but were not significantly handicapped. At 5.4 rpm, only subjects with low susceptibility performed well and by the second day were almost free from symptoms. At 10 rpm, however, adaptation presented a challenging but interesting problem. Even pilots without a history of air sickness did not fully adapt in a period of twelve days.
This suggests anywhere from 1-2 RPM could probably be workable, suggesting a practical radius of as little as 0.15 miles, or diameter of 0.3 miles (~241/482 meters). Further, this assumes 1g. It's highly unlikely that 1g is necessary.
Mars is one of the most likely targets for extended-duration missions, and has a surface gravity of 0.376g. So let's say 0.4g. This lowers the diameter to as little as 180 meters (~0.11 miles).
If you bring it up to 400 meters in diameter, or less than 1/4th of a mile, you can have 1 1/3rd RPM at better than Mars-equivalent gravity.
Finally, diameter/radius can be a deceptive way of looking at this, since a basic spinning station need not be circular. A first pass need be little more than a room attached to a counterweight with cables.

-- to Obama.
++ any body else.
Victory to anybody else, even sequestering US Federal funds to Puerto Rico and the USA eastern seaborad states will not save Obama.
Mr. Obama's grave is dug by his own hands!
Earth will be greatly benifited by the removal of Mr. Obama from this Earth.

O's big problem was that he was elected as a populist president, and so he had to focus on populist issues. As a space nut I hate to admit it, but space isn't a populist issue. Obama's Republican opponent, the moderate McCain, would have been better for the space program, because he can make a non-populist decision like spending or, rather, pushing Congress to spend a couple of billions more to put the Constellation program on the right track.
In Soviet Russia, ISS mothballs YOU!

On the other hand, it may turn out that an hour or two a day of artificial gravity counteracts the deleterious effects of microgravity. If that's the case, then motion sickness isn't really an issue. Astronauts could spend a small amount of their time in a relatively small spinning section and the rest in microgravity.
There are two Soyuz craft at the station, and 6 people.
One Soyuz "times out" in November. The other has 6 months more time remaining.
But this is not a hard timeout. It is due to batteries getting old, and corrosion from stored propellants.
One Soyuz will be coming home with its 3 crew in November plus or minus a few weeks.
The second Soyuz and its 3 crew will remain on the station for another 6 months plus.
So there is no chance of the station being empty before then.
Also winter weather is not a consideration. Russians have a history of landing spacecraft in any weather.
Gawd forbid if there were an asteroid headed to earth and we had to land a team on the surface to blow it up. We're doomed!!!
There are 2 groups of people you can make fun of on the Internet without fear of attack. The illiterate, and the Amish.
Human exploration has brought us to the moon
Apollo also brought us an insight into the early Solar System and Earth that the current robotic effort wouldn't have delivered.
You have to start somewhere.
But the continual acceleration that would be required would seriously eat into the delta-v of the ship, for it to function would require some form of constant twisting acceleration on the ship. Without acceleration you'll simply be moving with the ship in the same way it is spinning with everything else.
Circular would have a lot of static/stability advantages, though.
This aside, it's unfortunate that we can't really test the effects of long exposure to gravity between 0.1 and 1g, but if the experiments with people being kept in beds tell something, it might not be too good for us to remain in lower gravity for too long. It will certainly be better than microgravity and will prolong the time we can stay in space by alleviating the effects of weightlessness, but whether it is really enough to keep people healthy is a different matter.
Also, again, the smaller the diameter, the bigger the difference between gravity at your toes and at your head level, no matter how fast you spin it. Plus, those 180 meters you get down to is still heaps more distance than we achieve today with our current space stations, and even those parts are not made for constant stress of n (with n between 0 and 1) g pulling at their docking rings.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
A couple of notes here:
When Atlantis went up to the ISS a few months ago, the decision was made to have a smaller than usual crew. Instead of seven astronauts, only four flew up on Atlantis, while the rest of the mission was a resupply job. Officially, close to a year's worth of supplies were taken up to the ISS, giving it the ability to have just what happened occur, the loss of a supply capsule.
Now, this was one of the first failures of a Progress capsule. Considering that the rocket the Russians use has a 98.5% success rate (12 failures out of 799 launches) this is only a temporary setback. As has been noted elsewhere, the likelihood is that the Russians will get another Progress capsule up into orbit soon (there is a scheduled manned launch on 21 September and 29 November, and a Progress resupply on 26 October and 27 December). In addition, we have SpaceX doing a dock with their Dragon capsule, and I wouldn't be surprised if they launch it with supplies as well.
So no, I doubt that despite the sensationalized headlines that the ISS will be abandoned anytime soon.
[Disclaimer: I work for a prime contractor on the ISS, but the statements made are of my own observations.]
By that I mean, why can't they land the astronauts somewhere else with better weather if they need to?
a) T.G. for the superbly pragmatic Russian engineers who have, thanks to their skills in automated flight amongst other things, been keeping the ISS supplied (very well, with barely a hitch), for more years that I care to research. For *very little cost.
b) Get a life, or, at bare minimum, an education. The 'Soviet' of 'Russia' died a very public death about (thinks) 22 years ago? Where have you been in the mean-time? The Russian people have been to hell and back, and survived an awful social upheaval which, I hate to say, a certain capitilistic nation that occasionally flew big space darts would probably not have been *able to survive.
c) The superbly reliable Russian space vehicles will continue to be just that - reliable - and I'm sure that it will take them very little time to sort what has brought down this Progress vehicle. (Although, thinking of that issue, it may *not be easy. They have probably let their crash analysis team go, as they haven't had any work to do for so long, that the team were a drain on the (now capitalism-based society)'s budget.
I could go on, but it would just set more flames alight, and I'm for bed, and reflection, and to thanks to the Ruskies for great space vehicles that have kept the dream alive, *and for their fabulous aerobatic vehicles (a.k.a. aircraft.)
(Blast! This old coot can't remember how to log in. *Not anon., just ZoCool when I can recall how to do it! )
That's why you have more than one spinning ring and you have them rotate in opposite directions to counteract each other. Obviously it's not that simple, you need to dynamically balance the forces carefully to avoid the ship tumbling, but you don't need to use any thrust to do it. You would need energy, yes, but you wouldn't need to use any thrust.
If it does turn out that operating out of microgravity, but still at less than 1G is bad for you, it still might be the case that you can simply keep things at .5G and strap on 75 kilos of weights.
Yep, they call it torque...and electric motors provide it pretty well.
actually its not only possible but probable and practical. they will do it with cables radially supporting a ring of inflatable capsules. 2 rpm is an acceptable rotation that doesn't impose a problem with coreolis effect so no need for centrifuge training, and for 1 g, the diameter of the station would need to be a mere 448 m (224 m radius). Seems big, but remember the ISS is 109 m long and is supported by trusses instead of just cables.
