The Rapid Remote Sample Collection (RRSC) system is an innovative approach to the collection of regolith samples from the surface of comets or asteroids without landing the main body of the spacecraft on the surface. The RRSC system rapidly captures and retrieves a sample while the spacecraft momentarily hovers or slowly descends and-or drifts approximately 5 m above the body's surface. In this way the surface is not disturbed by landing thrusters, and the mass, volume, and complexity associated with landing and landing legs is eliminated. The sample collecting mechanism consists of an auger driven by the energy stored in a flywheel and a torroidal sample collection chamber wrapped around and rotating with the auger. The sample collector is deployed and retrieved by a Storable Tubular Extendable Member or STEM manufactured by TRW Astro Aerospace. This mechanism is similar to a motorized carpenters tape measure. Additional information is contained in the original extended abstract.
