Pyramid Comet Sampler, Phase I

Potential NASA Commercial Applications: 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. Lunar South Pole-Aitken Basin Sample Return could also benefit from the development of this sampling approach. Another mission that the Decadal Survey considered to be strategic for the planetary exploration was Cryogenic Comet Nucleus Sample Return (CCSNR ) Mission. However, the committee agreed that that mission (mainly due to lack of matured technologies) should be left for the 2020+ decade, while in this decade the required technologies (incl. sampling system) should be developed to TRL 6.
