Coolant Glitch Forces Partial Space Station Shutdown

samzenpus posted 1 year,10 days | from the its-getting-hot-in-here dept.

ISS 49

astroengine writes "A coolant system glitch on the International Space Station has forced several of the orbital outpost's modules offline as astronauts and ground control manage the problem. The crew are not in danger and ground control teams are currently working to see how best to troubleshoot. The issue, that occurred early on Wednesday, focuses on one of the space station's two external ammonia cooling loops, along which the station's electrical systems use to regulate their temperatures. The loop 'automatically shut down when it reached pre-set temperature limits,' said NASA in a statement. It is thought that a flow control valve in the ammonia pump itself may have malfunctioned."

Yes, "space stuff", like find and fix the common issues that will eventually crop up in a long-term flight or colonization project. Both Mir and the Shuttle ran into similar issues, so obviously one of the things they need to do before attempting to actually live further out than NEO is create a better cooling system. Not as flashy as building a new booster, but every bit as important.

With a 90 minute orbit, when exactly is that on ISS?

Re:Early on Wednesday (2)

Sockatume (732728) | 1 year,10 days | (#45668743)

The ISS is on UTC, and "Early Wednesday" presumably means early in one of the US time zones, so I actually can't give you an exact answer anyway because "early" isn't an exact time in the first place.

Re:Early on Wednesday (2)

Lumpy (12016) | 1 year,10 days | (#45669235)

Early means the first 8 hours of the day, so it happened between 0000 and 0800 UTC.
Mid UTC is 0800-1600
Late UTC is 1600-2400

Re:Early on Wednesday (1)

You're assuming the NASA release was written with reference to ISS time; I'm not sure that's the case given that news releases are normally intended for the press.

Meanwhile, the Russians used a pencil

Re:Meanwhile... (4, Informative)

fuzzyfuzzyfungus (1223518) | 1 year,10 days | (#45669531)

As it happens, the US and Russians used pencils at first; but concluded that unpredictable addition of conductive graphite dust to the closed interiors of expensive, accident-prone aerospace hardware was a bad plan.

The Russians used grease pencils as a substitute for a while, since the binder keeps the pigment from floating around, and NASA took Fisher up on their offer to test some of their fancy new pressurized pens, which they eventually adopted (as did the Russians).

Yep. Don't expect to ever see that again!

Nowadays a pen company would move to a state which promised them ten years of negative taxes (in order to "create jobs" and "compete with other states") and then get a federal grant for research in space pennery (as well as a tax credit for the entire sum of the grant, and the construction costs of all their buildings in the new state) and after five years they'd close down the plant, outsource production to China, and sell the intellectual property to a giant multinational corporation. At which point the criminals-in-chief would either buy immunity (by buying Congressmen and Supremes) or relocate to a 3rd world tax haven... before the first post-divestiture income and capital gains taxes came due.

Coming up with new ideas for turning raw materials into product is so last century, man. The new business model is to plunder states' treasuries and sell out. All you have to do is hate the rest of the human race and it's easy! GREED IS GOOD!

If memory serves (1)

Big Hairy Ian (1155547) | 1 year,10 days | (#45668983)

Mir had the same problem on a number of occasions so sounds pretty routine as space station problems go.

Re:If memory serves (2)

peragrin (659227) | 1 year,10 days | (#45669183)

in the ars article it mentions the coolant valves as one of 14 problems that come up regularly and are expected to be issues now and in the future.

or for a car analogy, even though you change your oil on a regular basis every once in a while you have to change the transmission oil too.

Re:If memory serves (1)

fuzzyfuzzyfungus (1223518) | 1 year,10 days | (#45669541)

It's the scary kind of 'routine', since cooling failure (on a spacecraft that gets a pretty good dose of solar radiation and has no atmosphere for cooling purposes) will definitely render the station incompatible with human life in fairly short order, possibly even get it toasty enough to destroy some of the less robust hardware; but, unfortunately, pumped coolant loops running in space are kind of touchy. Pity that Peltiers are so miserably inefficient and power hungry...

Re:If memory serves (1)

TangoMargarine (1617195) | 1 year,10 days | (#45674751)

How to dissipate heat in a near-vacuum sounds like an interesting engineering problem.

http://science.nasa.gov/science-news/science-at-nasa/2001/ast21mar_1/ [nasa.gov]

I managed to stay with them right up to the point where they said they radiated the excess heat into space...I thought that this entire setup hinged on the idea that vacuum doesn't conduct heat? Or is it like diffusion where heat wants to spread evenly, only in this case the diffused-to location is near absolute zero?

Re:If memory serves (1)

cusco (717999) | 1 year,10 days | (#45675419)

Right, there is no conduction because there there is no air/water/dirt to conduct the heat away. Instead they have to radiate the heat away into space, a process which is much less efficient. The cooling system panels glow in the infrared like crazy.

Re:If memory serves (1)

DanZ23 (901353) | 1 year,10 days | (#45671325)

Since it is so routine, I would think they would want to do it in a more preventative manner instead of waiting until critical systems have to be rerouted or shut down.

It is almost like they didn't want the engineers to come up with a plot resolving fix, just yet.

Re:Where is Geordie? (1)

fuzzyfuzzyfungus (1223518) | 1 year,10 days | (#45669555)

Somebody should really just tamper with the instruments on the ground. We all know that Mission Control is going to rerout the power to the secondary flux controller at the last moment; but they are waiting for the big bank of intimidating gauges and colored lights to show that only moments remain. We could save a lot of time by installing a 'false indication of crisis' feature to spur them to action ahead of time.

Re:Where is Geordie? (1)

X0563511 (793323) | 1 year,10 days | (#45672741)

AFAIK the coolants that would be used in that setting would be highly radioactive and/or toxic or extraordinarily hot - think "primary loop" reactor coolant. What the ISS is having problems with is more like the water cooling stuff in your car or PC (if you've a water-cooled CPU/GPU)

Re:Where is Geordie? (1)

TangoMargarine (1617195) | 1 year,10 days | (#45674815)

Companies seem to have a tendency to use extremely toxic chemicals wherever they don't expect humans to need to access the internals of the system...some nonsense about nature being inconvenient... :)

Get out the lasers! (1)

jbmartin6 (1232050) | 1 year,10 days | (#45669569)

Kind of funny to think of overheating in space, isn't it freezing cold out there? No conductor for the heat I suppose. Anyway, maybe this explains why self-replicating space probes haven't taken over everything, it gets too hot out there. Perhaps it is time to rig up some laser cooling [wired.com] on the ISS.

Re:Get out the lasers! (0)

Anonymous Coward | 1 year,10 days | (#45670625)

In fact, when our shuttles would complete orbital insertion, they would have to turn belly up and open the cargo doors in order to cool. If they doors didn't open they would do an immediate abort. Considering the payload would be stuck the mission would be a scrub anyways.

Re:Get out the lasers! (1)

X0563511 (793323) | 1 year,10 days | (#45672887)

I'm surprised they didn't have some kind of coolant media they could vent across exchangers to dump heat - you wouldn't need to carry very much, and you (generally...) only launch once on a mission.

Re:Get out the lasers! (1)

Sockatume (732728) | 1 year,10 days | (#45670643)

Space is very cold but it's also an almost-perfect vacuum, so like the coffee I put in my thermos five hours ago, hot objects can't cool easily. Objects making their own heat such as space stations and astronauts can be at a quite serious risk of overheating, especially if they're also being warmed by the sun.

isn't ammonia in cleaning products? (0)

Anonymous Coward | 1 year,10 days | (#45672443)

never knew ammonia is a coolant. I always thought it is a gas in cleaning products. Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. It is a colourless gas with a characteristic pungent smell. Now I'm confused.

Re:isn't ammonia in cleaning products? (1)

pr0fessor (1940368) | 1 year,4 days | (#45730657)

Ammonia was one of the first coolants used more commonly in food industry, my brother has been wanting to get an air conditioner for his home that uses ammonia refrigerant but they are mostly commercial.
