PROJECT DESCRIPTION

The scope of our project is to return samples from the asteroid, Psyche. The operation will be carried out in three stages: impact, collect, and return. This process took inspiration from NASA’s OSIRIS-REx sample collecting mission with its highly efficient TAGSAM mechanism (Touch-and-Go Sample Acquisition Mechanism: a robotic arm combined with pneumatics to blow up and collect particles). This mechanism eliminates the high cost and complexity of a system using a lander, a rover, and returning propulsion. Our three-stage approach similarly aims to achieve this efficiency with adjustments to adapt to Psyche’s highly dissimilar gravitational and metallic characteristics. An impactor will be sent to Psyche’s surface to create a spray of debris, which will be collected by a small rocket sent from a satellite in Psyche’s orbit. The small rocket will return to the satellite, which will be returned to Earth, once the samples have been collected. Our group is primarily focused on the collector/mechanism housed in the small rocket to acquire these samples.

The overall small rocket shape and capsule designs were inspired by NASA’s Stardust mission. The capsule on the front of the drone will contain the collectors and prevent contamination. The team is still in the process of selecting a collector concept, so both the net and disk collectors are shown in the assembly views below. The Disk will be double-sided to ensure that samples of varying sizes and properties are collected. One side will consist of a grid-like pattern to hold Aerogel. The other side will include electromagnets to collect the magnetic metallic particles from the debris field. The net concept has a mesh back made of Kevlar and an opening that
consists of a titanium ring with holes to attach the Kevlar mesh and a metal grid-like front.
