NASA Astronomers To Observe Hayabusa's Fiery Homecoming
coondoggie writes "NASA said that a group of its astronomers will have a front row seat in Australia to watch the Japanese spacecraft Hayabusa's high-speed, fiery return to Earth. It is bringing with it a hunk of the asteroid Itokawa. The spacecraft is expected to land in an unpopulated area of Australia at approximately midnight locally, or 7 am PDT, on Sunday, June 13. Some 30 NASA astronomers will be flying onboard a specially equipped DC-8 with instruments that can monitor Hayabusa's reentry."
JAXA is not at all certain that it is bringing a "hunk" or much at all of Itokawa back with it. The firing mechanism which was meant to fire a bullet into the asteroid malfunctioned. They're just hoping it picked up enough residue. After the various mishaps this spacecraft encountered, it's been a good effort to get it home.
I've got news for Mr. Santayana: we're doomed to repeat the past no matter what. That's what it is to be alive.
Though I recall that when the vehicle bounced off the asteroid the operators had no idea whether it had collected material from the surface and it is likely they still don't know.

There's an important point to the re-entry process, separate from the asteroid sample: the craft will be coming at interplanetary speed (about escape velocity from Earth) -- is much faster than typical re-entries from Earth-orbit. Seeing if the heat-shielding technology will work is important for future missions around the solar system.
Considering they lost one of the shuttles and it's ENTIRE FUCKING CREW due to A HEAT SHIELD FAILURE, it seems that taking advantage of any available research opportunity into heat shielding is A GOOD IDEA!
Maybe you don't like NASA spending money on space.
After all, we don't know what gains we'll get from it.
Now that may be true, but then again, they've got a really good 'payback' rate, even if they aren't a profit center.
You like your cellphones, your satellite or cable tv, weather reports and warnings, tons of materials, medicine, maths, electronics, and so many other things you could write a book about it, and people have, you really should thank NASA. Their contributions to the total knowledge and even applications of that knowledge is absolutely huge and in almost all fields of endeavor. (Except porn, I really don't think NASA has done anything on human sexuality in space, but I'm not sure of that.)
So if you want to crawl back into your cave and ignore the contributions they made and ignore the even greater ones that can only come about if they are allowed to do that research you call "boondoggles", then just remember the reply Faraday gave when asked what use electricity was, he simply replied, "What use is a baby?".
