The NASA 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. 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 and sample its surface. 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 designed a sampling system capable of effectively extracting scientific samples from each of the hypothesized surfaces, including: mostly flat metallic surface, flat metallic with metal and/or rocky debris, rough/high-relief metallic and/or rocky terrain, high-relieve metallic crater walls.
