Artemis II Astronaut Health

The 'AVATARS' project aims to gain insights into how space travel affects cellular health and aging, data that was never captured during the Apollo era.

Upon their return tonight, the crew will undergo extensive testing to monitor changes in their bone density, cardiovascular systems, and cognitive functions.

Scientists are particularly interested in how the 10-day journey has impacted their immune responses and DNA integrity.

These findings are considered essential for planning future long-duration missions to Mars and establishing a permanent lunar base.
