NASA's spacecraft Stardust, flies within 155 miles from the comet P/Wild 2, on January 2, 2004 and collects dust grains and the cometary material. Stardust sealed its collected matter inside a sample reentry capsule, which separated from Stardust and landed in the Utah desert on Jan. 15, 2006. They were later revealed to contain the amino acid glycine, an essential building block of life.
