Re: Genesis Capsule Crashes

I saw an image of it with a guy next to it. Can't find it now. It's about 5 feet in diameter.

The rumor around building 198 is that the Li/SO2 battery may have passivated and couldn't provide enough charge to fire the pyros. I also heard that what cratered into the Utah desert isn't the Genesis payload, but the UFO that collided with the "real" Genesis payload on descent.

I thought the samples were expected to be "embedded" in the collection disks, and would thus be slightly protected from contamination by simple exposure to air (and/or dirt). They're not going to be the pristine samples of solar wind they ought to have been, of course, but there should still be plenty of useful information to be gotten.

Click on image for CNN's coverage

^^ There's a pretty cool animation of what the helicopters would have done, had the parachutes deployed. Check it out.

3 planes? I thought you only had one:

Your Air Force can almost have its own airshow team now - "The Hummingbirds".

Well we call them planes. Some people call them ultralites. :rolleyes:

No no, he's right... we only have 1 plane. The other two were the sea-king helicopters, but they crashed and burned.

C'mon people. Where's the support? Why not say "I hope there's something salvageable so the science isn't completely lost" or "It's ashame what happened after so much time and effort put into it" rather than "Geez, NASA, another screwup" or "it's not the first time they've screwed up"

Let's be a a little more supportive of this great program we call NASA.

When was the last time you launched ANYTHING into space? Yeah, that's right, NEVER! So don't promote their failures when you haven't even attempted success.

Well actually, no, wait a minute... that only made it about three feet. :p

But I agree, stuff happens, being in FIRST everyone should know plenty about that. But just look at all of the successes that NASA has had as well, and I don't think anything, even not this, would be a real failure, this is just another lesson to learn from.

David Lindstrom, Genesis program scientist, said NASA was "optimistic" about retrieving scientific data from the mission.

"We think we can remove most of the impurities from the surface and science will be possible," he said. "The solar wind particles are implanted within the collectors so the absolute surface is not all that critical. We are hopeful of getting science out of this."

In that case, would it have been possible to implement some kind of ground control override? Send up an RF signal to force the parachute to deploy?

The rumor that have been circulating around the JPL flight community for a few weeks has been shown to be true. The accelerometer was designed-in upside-down and couldn't detect the reentry deceleration.

Re: Genesis Capsule Crashes

I understand that both the main and back up accelerometers where placed upside down. If so then it was a human systems failure. Similar thing constantly happen on our team.

Give me billions of dollars in Government Funding and then maybe I can try ;)
