NASA's OSIRIS-REx will land on an asteroid to bring home rocks and dust – if it can avoid Mt. Doom

OSIRIS-REx will touch down on asteroid Bennu, collect a sample of the dust and begin its journey back to Earth, where scientists will study it, hoping to learn secrets of the solar system's origin.

Meteorites from Mars contain clues about the red planet's geology

Martian meteorites allow scientists here on Earth to decode that planet's geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
