A Comet Surface Sample Return System, Phase I

The acquisition of surface samples from small interplanetary bodies such as comets and asteroids, as well as small moons like Mars' Phobos, and Deimos holds great scientific interest. Under the NASA Authorization Act, Congress instructed NASA to "plan, develop, and implement a Near-Earth Object (NEO) Survey program to detect, track, catalogue, and characterize the physical characteristics of NEOs equal to or greater than 140 meters in diameter in order to assess the threat of such near-Earth objects to the Earth." In 2010, President Obama called for a new approach to space exploration, which would include human and robotic exploration of asteroids. In the latest Decadal Survey, the committee recommended selecting a Comet Surface Sample Return mission as one of the five New Frontiers 4 (NF4) missions, solidifying the importance of studying returned physical samples from a comet. The other four included Lunar South Pole-Aitken Basin Sample Return, Saturn Probe, Trojan Tour and Rendezvous, and Venus In Situ Explorer. The Lunar and Venus missions could also benefit from the development of this sampling approach. The sampling probe in the proposed effort could be applied to any number of planetary bodies with a microgravity environment where sample return is desired. More »
