Discovery Prepares for Return

Kailash Nadh writes "Discovery's astronauts packed up their stuff on Friday as they prepared to undock from the international space station now that NASA has cleared the shuttle to return to Earth next week. Their most difficult task before leaving the station was the maneuvering of a huge cargo container filled with 2 1/2 years worth of trash into the shuttle's payload bay. Once back on Earth, the items would either be disposed of or returned to researchers."

Aldrin

I find it interesting that Aldrin is critical of the shuttle program. I know there are a lot of people unhappy with it, but it seems a name as big as Aldrin being critical has quite a bit of meaning. Hopefully this is a sign of a new approach to space travel in the future.

There's quite a bit of tradition at NASA. For example, the CAPCOM is always an astronaut. This person is, alone, tasked with relaying information between command and shuttle crew. Seems experience as an astronaut is mandatory for conveying essential information in critical times.

So my guess is Aldrin brings up something important to "the continuity of space exploration" in the same way. Whether you thing this is a PR move or not, I think having people with (successful) field experience in the decision structure is tremendously important. I think the 2 shuttle disasters showed how much managers not grounded in reality can be, well, disastrous.

Implements of destruction

"... So we went out there with our shovels and rakes and implements of destruction, and we loaded all that trash into the back of a Boeing orbiter, went back inside the space station, and had a Thanksgiving dinner that couldn't be beat."

Well they're going home anyway, it's not like they're doing the trip just to take the rubbish back

It's probably useful to know what happens when you keep rubbish in space for several years anyway

A reason to bringing back the waste.

[Chonine]

It is very possible that what we consider waste and what NASA does could differ. Remnants of experiments, minilabs that belong to schools, old journals, outdated equipment, failed equipment... I think a big part of the reason to take it all back is so the engineers can find out failure points, reuse or sell older equipment, for NASA historians and archivists to keep any documentation, and to give loaned items back to their respective owners.

The reason they don't throw it into the atmosphere is for a variety of reasons.

They catalog everything that comes back. They weigh and measure each piece that is returned. They check it for radiation contamination (something that would spread the radiation if it was sent into the atmosphere to burn up). They do tests and experiments to see how the items faired during a long duration such as 2.5 years in space without the protection of the Earth's atmosphere from all the X-Rays, Gamma Rays, etc...

It's more than just garbage when it comes back, it turns into a science experiment in of itself. I'm sure they collect just as much data on items in space from the garbage that is brought back as they do from the experiments that used those items in the first place.

Garbage scow

Their most difficult task before leaving the station was the maneuvering of a huge cargo container filled with 2 1/2 years worth of trash into the shuttle's payload bay.

When, at the age of seven, I sat enthralled by the Apollo XI landing in 1969, I would never have believed that our most sophisticated space vehicle in 2005 would be an aging garbage truck traveling a couple of hundred miles from Earth to visit a space station with no purpose.

I can't even think about this for too long; I start shaking with the force of my anger and disappointment.
