Three years ago, NASA launched the Genesis mission. The satellite spent more than 1000 days orbiting the sun, collecting particles that are part of the solar wind. By the time the return capsule enters the Earth’s atmosphere, it will be travelling twenty-five thousand miles per hour. Then it will be caught, in midair, by a helicopter.

All of this to bring less than a half of a milligram of stellar matter to the ground.

Update 09-08: The parachute (that I forgot to mention was supposed to open during reentry, before the probe was caught by the helicopter) failed to open, and the Genesis return capsule slammed into the ground. Breaking news stories on Google News.
