1.4kg fabric 'exosuit' uses artificial muscles to simulate Earthlike loading and improve astronaut mobility

The University of Bristol built a 1.4kg fabric-based exosuit that uses artificial muscles to simulate Earthlike loading, aiming to curb microgravity-driven muscle loss and offset the resistive effects of pressurized EVA suits. Early lab tests in simulated lunar and Martian EVAs show measurable mobility gains without major movement penalties.

Briefing

What Hype is tracking

  • The suit targets a core physiological problem: astronauts still lose significant muscle mass on long missions despite 2–3 hours/day of exercise; a 1.4kg fabric exosuit that simulates Earthlike loading could materially reduce that risk and downstream medical and mission costs.
  • Early tests show improved mobility in simulated lunar and Martian EVAs, indicating potential integration with evolving surface-operations plans and prototype suit evaluations such as ongoing prototype Artemis lunar-surface spacesuit testing and Axiom/Artemis III suit development work (first prototype validation).
