Final answer:
The four effects-based mission areas within the Aerospace Medical Program are generating propulsive fuel away from Earth's surface, ensuring long-term health of muscles and bones in low gravity, and resource extraction for construction materials in space.
Step-by-step explanation:
The four effects-based mission areas within the Aerospace Medical Program are:
- Generating or collecting propulsive fuel away from Earth's surface
- Long-term health of muscles and bones for periods longer than a year in low gravity environments
- Resource extraction for in-situ construction materials
These mission areas focus on various aspects of space travel and exploration, such as propulsion, human physiology in low gravity, and utilizing resources in space.
