One of the primary mission objectives for the Mars 2020 rover is to drill rock core samples and store them in tubes that could be retrieved and returned to Earth on subsequent missions. A major challenge to the success of this mission is achieving hermetic-level seals on the tubes that contain the rock samples in order to preserve relevant science data. .
Objective ot this project was to investigate sealing methods for encapsulating samples in 1 cm diameter thin-walled sample tubes applicable to future proposed Mars Sample Return Techniques implemented include a spring energized Teflon sleeve plug, a crimped tube seal, a heat-activated shape memory alloy plug, a shape memory alloy activated cap, a solder . A sample acquisition and caching architecture has been developed for the proposed Mars 2020 mission that acquires samples directly into sample tubes in coring bits.
