Human spaceflight poses physiological risks, including effects of weightlessness on bodily functions. Further research is needed to understand these changes and ensure astronaut safety during space missions.

Area of Science:

  • Space physiology
  • Human adaptation to spaceflight

Background:

  • The Challenger disaster highlighted spaceflight hazards.
  • Prolonged weightlessness causes significant physiological changes.

Purpose of the Study:

  • To review the physiological effects of weightlessness.
  • To identify knowledge gaps in space physiology.
  • To highlight Spacelab's research potential.

Main Methods:

  • Review of existing US and Soviet space experiments.
  • Analysis of known physiological changes.

Main Results:

  • Weightlessness impacts vestibular, bone, muscle, cardiovascular, blood, renal, and pulmonary systems.
  • Significant knowledge gaps persist despite extensive research.
