Developing a Comet Harpoon for Sample Return

December 13, 2011

The Comet Nucleus Sample Return mission will collect subsurface samples from a comet and return them to Earth. Comets and asteroids are leftover remnants from the early solar system and by studying samples from these objects, we can learn more about the formation of our solar system and may find clues to the origin of life on Earth.  credit:  NASA
