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)."
Oh, and the first announcement is out on the NASA conference next year on The Importance of Solar System Sample Return Missions to the Future of Planetary Science, March 5–6, 2011. Hope the Hayabusa scientists get to go.
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.
