For the first time after the Apollo moon landings, NASA is launching a mission into outer space to
bring back extraterritorial material. This time, NASA is going after comet and interstellar dust.
"Stardust", the robotic spacecraft that will collect the tiny grains, is scheduled for a journey of seven
years that will cover 5.1 billion kilometres. It is NASA's first attempt to bring back pieces of a comet.
This particular comet, Wild -2, rarely came close to the Sun until the 1970s, and so still should
contain the original, frozen components of the solar system. By studying samples from this well -
preserved comet, scientists hope to better understand how icy, rocky comets may have provided the
water and organics necessary for life to form on the Earth, and possibly elsewhere.
