Area of Science:

  • Space Medicine
  • Aerospace Engineering

Background:

  • Extravehicular activity (EVA) requires astronauts to undergo prebreathe protocols to prevent decompression sickness.
  • The Space Shuttle Program utilized specific prebreathe procedures to ensure astronaut safety during EVAs.

Purpose of the Study:

  • To detail the prebreathe protocol for Space Shuttle Program extravehicular activity.
  • To compare planned versus actual prebreathe protocols during the STS-37 mission.

Main Methods:

  • Descriptive analysis of the established prebreathe protocol.
  • Comparative analysis of planned and executed prebreathe procedures for STS-37.

Main Results:

  • The prebreathe protocol ensures astronaut safety during extravehicular activity.
  • Analysis of STS-37 mission data revealed adherence to the planned prebreathe protocol.

Conclusions:

  • The described prebreathe protocol is effective for safe astronaut extravehicular activity.
  • The STS-37 mission validated the efficacy and execution of the prebreathe protocol.
