Technical Abstract (Limit 2000 characters, approximately 200 words):

Cornerstone Research Group (CRG) proposes the development of a dust tolerant joint to facilitate reliable payload reconfiguration and automated in-space construction in regolith inundated environments. CRG will demonstrate a lightweight, mechanically robust joint capable of securing structures while exposed to regolith particles of similar size to what are known in various space environments such as the lunar surface. This state-of-the-art dust tolerable joint leverages CRG’s shape memory polymer (SMP) reversible joining system, which facilitates self-alignment, low dexterity operation, capture and lock features, electrical isolation, and connectivity feedback if desired. Additionally, CRG’s dust tolerant reversible joint provides NASA with a scalable, modular joining capability that can be used with autonomous assembly systems. Leveraging CRG’s prior development work on shape memory polymer fastening systems and mechanical design expertise, the proposed R&D herein will provide NASA with a multifunctional dust tolerable reversible joint with technology readiness level (TRL) of 4 at the conclusion of the Phase I effort.

Potential NASA Applications (Limit 1500 characters, approximately 150 words):
  • In-Space structural assembly and construction
  • Moon to Mars Campaign
  • Commercial Lunar Payload Services (CLPS)
  • Rotary, linear, and static joints
  • Manned and unmanned space vehicles
  • Payload attachment and removal
  • Satellites, solar arrays, and deployable structures
Potential Non-NASA Applications (Limit 1500 characters, approximately 150 words):
  • DoD and commercial satellite construction, expansion, refurbishment and In-Space test ranges (i.e. orbital outpost)
  • Deployable solar arrays, antennas, and variable vibration damping structures
  • Reusable launch vehicles and payload delivery systems
  • Space transportation vehicles
  • Remote terrestrial shelter construction
