MONTREAL — The Artemis II mission highlights how deep space poses new challenges for the human body, even on a short 10-day journey, with risks such as radiation and other effects that scientists are still studying.
Dr. Farhan Asrar, a space medicine expert, explains how deep space travel affects astronauts’ bodies and minds, from fluid shifts and muscle loss to radiation exposure and confined living conditions.
They must adapt to microgravity, maintain fitness with innovative exercise equipment, and manage limited resources and space.
The crew aboard the Artemis II mission is about four days into a 10-day journey, which includes a lunar flyby in a compact capsule the size of a campervan.
