Scientists at the Johnson Space Center in Houston, Texas, realize that the Stardust mission was a success as they remove the aerogel trap filled with comet dust from the space probe. The Stardust probe returned to Earth on Sunday after completing a seven year, 2.9 billion mile trip to comet Wild 2 where it captured samples from the comet's tail.
Scientists uncovered pieces of comet dust which was captured in aerogel, a sponge-like solid made of 99 percent empty space. NASA reported that the number of samples exceeded expectations.
Here's another closeup look at a cometary fragment that was caught by aerogel.
