Hayabusa Captured Asteroid Dust Confirmed 60
astroengine writes "It's been a seven-year roller-coaster ride for the asteroid sample return mission, but JAXA — the Japanese space agency — has confirmed that 1,500 particles of dust from the surface of asteroid Itokawa have been found inside the sample return capsule. The capsule parachuted to Earth shortly before the Hayabusa spacecraft reentered over the Australian Outback in June. Since then, scientists have been painstakingly analyzing the capsule's contents to make sure the dust they found wasn't terrestrial contamination. Now they are sure, making this the first time a sample has been collected from the surface of an asteroid (and only the second time a sample has been returned from a celestial object, the first being the Moon missions)."

Not exactly. [nasa.gov] Unless you don't consider comets "celestial objects."

Just cause we don't have to go out into a vaccum to collect stuff from them does not mean they cease being celestial in nature right? Right?

If we're going to argue over semantics, technically they're not. A celestial object is something you naturally see in the sky. An asteroid is a celestial object, but upon impact with the earth it becomes a meteorite.

It's not just semantics, it is a meaningful distinction, since it undergoes significant chemical changes as it heats up in the atmosphere. Besides, every atom of the Earth was part of a celestial object at some point in the past.

Wrong. Read the sentence again: "making this the first time a sample has been collected from the surface of an asteroid (and only the second time a sample has been returned from a celestial object, the first being the Moon missions)." The key phrases here are "has been collected" and "has been returned", which implies that human activity brought these samples to Earth, rather than natural events.

I did read it again as you suggested. However, if you read it again, you'll note that there is absolutely no mention of going into space to do the collection. For that matter, there is also no mention about where the stuff is returned to.
If it said 'collected from the surface of an asteroid in space' and 'returned to Earth', I'd be forced to follow their train of thought.

That kind of stuff is usually figured out pretty easily logistically. There's really only a small window where re-entry can be done with enough safety to preserve whatever it is you're bringing back. So you know the weight - and the speed it's currently at - and you use that to calculate the angle for re-entry and then its a simple high school physics problem to find out where it'll land.

Furthermore, this mission helped JAXA further configure their deep space communications network which will be shared with other space-faring nations in the future. The more players we have in the space race the better it will be for everyone involved. Increasing the number of tuned and configured deep space communication antennae increases the total throughput of data that can be processed by partnered space agencies. Again, this correlates to a potential increase in scientific data returned from future missions.
Finally, Hayabusa actually touched down on the asteroid. The data collected by JAXA during this maneuver will prove to be invaluable for future missions that involve low-gravity objects (comets, asteroids, small moons, etc.). All in all, the data and experience gained by the Hayabusa team will pay off in the space industry for decades to come with or without the asteroid dust. That's not to belittle the sample return. That, too, is a great achievement. However, it is important to note just what a tremendous step this mission was for the space industry in general.
