The Psyche mission is set to launch in 2022 and arrive at the asteroid in 2026. It is an orbiter mission and will not land on the surface. Instead, it will spend 21 months performing science operations from four staging orbits, which become successively closer. This will be NASA’s first space mission to a world likely made largely of metal, rather than rock or ice. The Psyche mission will take a giant step forward in our understanding of this mysterious world. It is possible to imagine, however, that after learning about Psyche from orbit, there may be scientists and engineers interested in proposing a subsequent mission to actually land on the asteroid to explore and sample its surface. Capstone teams are invited to take on that challenge!

Designing to the range of hypothesized surfaces that might be found at Psyche (and keeping in mind other constraints such as its gravity), the team is designing and prototyping a sampling system capable of effectively extracting scientific samples from each of the hypothesized surfaces and, potentially, a single caching system able to cache each type. Hypothesized surfaces may include: mostly flat metallic surface, flat metallic with metal and/or rocky debris, rough/high-relief metallic and/or rocky terrain, high-relief metallic crater walls.

This work was created in partial fulfillment of Arizona State University Capstone Courses “SES 410”.
