Oxygen Supply

The spacecraft and space suits provide a steady flow of oxygen. Carbon dioxide is removed using filters like lithium hydroxide canisters.

Food and water

Food and water

Astronauts eat specially packed, lighweight, and shelf-stable food. Water is recycled from recycled from urine, sweat, and air moisture using purification systems.

Temperature Control

Temperature Control

Spacecraft are equipped with thermal regulation to protect against extreme heat and cold. Space suits also have layers to insulate and manage body temperature.

Radiation Protection

Radiation Protection

Spacecrafts have shielding to reduce exposure to harmful cosmic and solar radiation. In high radiation events astronauts take shelter in thicker parts of the spacecraft.

Microgravity Adaptation

Microgravity Adaptation

Astronauts exercise daily for up to two hours to prevent bone weakening and prevent muscle loss. Equipment like resistant machines and treadmills are used in zero gravity.

Communication with Earth

Communication with Earth

Constant contact with mission control via satellite and radio systems ensures updates, emotional support and guidance.

Mental and Physical Health Monitoring

Mental and Physical Health Monitoring

Medical kits, psychological support and regular check-ups keep astronauts healthy. Virtual calls with family and leisure time are scheduled to reduce stress.
