Hayabusa Captured Asteroid Dust Confirmed
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. Unless you don't consider comets "celestial objects."
This is the third time a sample has been returned from a celestial object. The second being the Stardust program from NASA that brought back material from the tail of a comet.
No one named an asteroid "Pixie". That would have been so cool! :)
Geekism is your _only_ God!
Alien Dust acquired; check.
Scientists analyzing it in labs; check.
Cue horrific mutating space monsters.

Uhh, the Russians would like a word: LUNA 16.
Why do we forget the accomplishments of the Russians?
So I hope "the Moon missions" includes the Russians, not just Apollo? Yes? Spaceeba!
Bravo. Now, do it again !
Lucky break they got, recovering the capsule themselves. Imagine what would have happened if some country bumpkin comes across the capsule and decides to find out what is inside by drilling a hole. Do we really have a six level underground containment facility for that eventuality?

Congratulations, little Hayabusa and all your friends, and in the spirit of celebration, may I be among the many to exclaim, YATTA!
I believe that the manned US missions to the Moon and the automated Soviet spacecraft Luna 16, Luna 20, and Luna 24 all brought lunar samples back to Earth - but who's counting?
After all the travails and troubles this mission has encountered, actually recovering comet dust is - at last - cosmic justice.

This successful mission conclusion is of critical importance to not only science but also the well-being of our civilization.
Hayabusa has proven that we can send a probe to an asteroid, dock with it, overcome all the odds and return a sample of dust back to Earth. On a global scale, our understanding of asteroids has just been enhanced, helping us better understand these potentially hazardous space rocks, ultimately aiding our ability to deal with them should a "big one" be aimed right at us.

I can't help but imagine a guy in a spacesuit riding a motorcycle into space when I see headlines about this mission. Good name.
To me, the most important aspect of the satellite was more of a demonstration of capability. It was able to overcome significant problems (damage to solar panels, etc) and complete its mission. Much of future utilization of space will likely be via robotic and remote systems. As a initial effort in this direction, it was impressively successful, not as much in what it accomplished, but more in what it overcame.

Well at least your nickname is fitting....

...Seriously, there used to be patriots in this country and now it's just apologists and internal enemies working against us to help other multinational corporations.
We call them democrats and republicans respectively.
I read someplace scientists were concerned about bringing celestial matter to earth because this would require recalculating atomic weights in the periodic table. Any chemists want to comment on this?

One of the other very important achievements of the Hayabusa mission was its successful demonstration of ion propulsion technology in spacecraft. Hayabusa was one of the first full-scale implementations that relied entirely on a redundant configuration of ion drives. While three of the drives ended up failing by the end of the mission (the missions lifetime was extended far beyond the planned operational life of the spacecraft), the configuration demonstrated that a redundant system could be used to account for thruster failures. Furthermore, the demonstration of this particular technology will decrease the risk factors associated with ion propulsion technology, thus encouraging its adoption in future space missions. This new technology should help to reduce fuel load on future spacecraft, thus increasing the size of any particular mission payload. In other words, we will be able to get more science bang for our space buck because of the technology demonstrated in this mission.
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.

I really, really want to make another Ninja Gaiden joke, but after all the stories about this spacecraft I just don't have another one in me. Sorry, Slashdot. I have failed you.
