Aviation, Space, and Environmental Medicine
|December 1, 1983
Summary
Spacelab-4 will investigate how weightlessness affects living systems, including humans and animals. This mission focuses on physiological changes and validating animal models for spaceflight research.
Area of Science:
- Life Sciences
- Space Biology
- Physiology
Background:
- Spacelab-4 is the first Spacelab mission dedicated to life sciences.
- It will investigate the physiological effects of acute weightlessness on various living systems.
Purpose of the Study:
- To explore the effects of acute weightlessness on human and animal physiology.
- To validate animal models for human physiological responses in microgravity.
- To study cardiovascular adaptation, vestibular function, and fluid shifts.
Main Methods:
- Integrated payload with human and animal investigations.
- Subjects include humans, monkeys, rats, plants, and frog eggs.
- Focus on physiological changes observed in previous manned spaceflight.
Main Results:
- Primary objectives: cephalic fluid shift, cardiovascular adaptation, vestibular function (space motion sickness).
- Secondary objectives: red cell mass, nitrogen balance, calcium metabolism, immune function, plant gravitropism, frog egg development.
- Comprehensive study of microgravity's impact on diverse biological systems.
Conclusions:
- Spacelab-4 aims to provide integrated data on weightlessness effects.
- Findings will enhance understanding of human adaptation to spaceflight.
- Validation of animal models is crucial for future space exploration.
