US probe 'Stardust' returning to Earth with rare samples - Yahoo! News: "WASHINGTON (AFP) - After a seven-year journey, US space probe 'Stardust' is scheduled to deliver to Earth on Sunday samples of rare dust it has collected from stars and comets that scientists believe could offer vital clues about the solar system's origins.
A capsule weighing 46 kilograms (101 pounds) and carrying a teaspoonful of space dust is expected to land in a Utah desert at 1012 GMT Sunday after flying 4.63 billion kilometers (2.88 billion miles) in space, or 10,000 times more than the distance separating Earth from the Moon."
