Space Station Leaking Vital (chilled liquid ammonia) Coolant, NASA Says
Yahoo! News ^ | Clara Moskovitz - Space.com

Posted on 05/09/2013 6:23:28 PM PDT by NormsRevenge

Astronauts on the International Space Station have discovered a leak of ammonia coolant on their orbiting habitat, and NASA is looking into the problem, though it poses no immediate danger to the crew, officials said today (May 9).

The space station uses chilled liquid ammonia to cool down the power systems on its eight giant solar array panels. A minor leak of this ammonia was first noticed in 2007, and NASA has been studying the issue ever since. In November 2012 two astronauts took a spacewalk to fix the problem, rewiring some coolant lines and installing a spare radiator due to fears the original radiator was damaged by a micrometeorite impact.

At the time, those measures appeared to fix the problem, but today astronauts on the football field-size space station noticed a steady stream of frozen ammonia flakes leaking from the area of the suspect coolant loop in the Photovoltaic Thermal Control System (PVTCS).

"It is in the same area, but we don't know whether it's the same leak," NASA spokesman Kelly Humphries of the Johnson Space Center in Houston told SPACE.com. Humphries said the agency was taking the leak seriously because it affects an important system — if they loose the ability to cool that particular solar array, it won't be able to generate power for the station. In fact, the leak has worsened to the point that Mission Control expects that particular loop to shut down within the next 24 hours.

However, "the crew is in no danger," Humphries stressed. It's too soon to speculate on a possible spacewalk or other measure to deal with the issue, he added.

Mission Control has been discussing the problem with the astronauts on the station throughout the afternoon.

maybe NASA just needs a little Muslim Outreach to reach up there and fix it?

Call the new Transportation Secretary to build a trolley to the Space Station. ;-)

rewiring some coolant lines

Coolant lines are now wire. Who knew?

Journalists are idiots.

From my experience in large organizations, it's just about time to form a committee to set up a meeting schedule to define the agenda for a focus group to consider discussing the problem.

Just imagine when this kind of problem pops up for the “one way ticket to Mars” settlement.

Well, it could be worse. If they were leaking Freon 21 the EPA would drive up there and shut them down for polluting!

Just send a repair crew and parts up on the next shuttle.

We need a space hazmat team. If we let R12 or 134a or anything like that out in the air we get arrested.

Somebody send up some Rednecks who understand how to fix these things.

2007? LOL. If you discover a slow leak in a tire on your riding lawnmower, I could understand putting it off for 6 years, but it seems that fixing this leak might have been a wee bit more important.

Obama would never leave behind an American in harms way, so we know not to worry. Besides, Obama’s Muslim NASA will figure it all out. Heck, we would have never made it to the Moon without all of those Ali Baba wizards.

Road lights? It’s only 12 um something and 100 others and to use 10 wire. I suppose that’s just to keep them on the bumper, and I think is overkill, cause the Warn has 8 wire, and it’s much bigger, and hasn’t fallen off yet., but it’s gonna all be okay, cause I don’t need 200 of lights to winch out, and I don’t need to winch at 70 on the slabs. And the limiter kicks out at 6.

See, balance in the universe.

Okay, here’s the units I used in the above stuff... volts, whats, gauges, what the hell is a gauge?, oh, and miles in a hour, and revolts in a standard, non-metric minute. At sea level. Attention to detail - it’s a engineer thing.

This is probably ammonia in “heat pipes”

HAL just renamed the AE35 unit an “ammonia leak”. Don’t go out without your helmet Dave.

The committee to select the blue ribbon panel to select commission members is working on it feverishly even as I write this.

Yes. Thank God we have a shuttle to fly back and forth to help out on issues like this. Oh. Wait. I got laid off at KSC in August 2011 when the last flight was over and the orbiter secured. Ooppps! Oh well, it cost too much anyway.

I just heard a FEST was prepping to go help. Sadly, they were told to stand down. Don’t know who said that but it must have been high up. Like the ISS.

if they loose the ability to cool that particular solar array, it won't be able to generate power...

Cage the ability.

All the lazy Rat-voting parasites need all their free stuff so the frivolous military and NASA spending needs to cut their “fair share”.

NASA is just a shell and some buildings... obama has killed them. Unless we want to pay the Russians millions per ride... we do not have the capability to put a man into space.
