Area of Science:

  • Space Engineering
  • Human Spaceflight Systems
  • Life Support Systems

Background:

  • European Extravehicular Activity (EVA) space suit predevelopment activities have generated significant technical data over two years.
  • Understanding of space suit mobility and life support functions has improved, influencing design consolidation and re-evaluation.

Purpose of the Study:

  • To present the latest design status of the European EVA space suit concept.
  • To emphasize improvements in crew safety, comfort, and productivity for the European Space Agency (ESA).

Main Methods:

  • Consolidation of design features based on test data and system understanding.
  • Challenging existing design solutions to optimize mass, cost, safety, and handling.
  • Incorporating evolving requirements from the Hermes spaceplane and operational scenarios with Columbus.

Main Results:

  • An improved technical reference concept for the European EVA space suit.
  • Enhanced functional safety and ease of handling in the space suit design.
  • Implementation of necessary hardware and functional redundancies for operational scenarios.

Conclusions:

  • The predevelopment activities have resulted in a robust European EVA space suit concept ready for Phase C/D development.
  • The design prioritizes crew well-being and mission effectiveness within mass and cost constraints.
  • The concept aligns with the operational needs of the Hermes spaceplane and Columbus module servicing.
