Described as the “perfect space crop,” the nutritious and ready-to-eat fungus could be a key stepping stone toward fueling crew members during long-term spaceflight

The Fram2 crew will be the first people to observe the polar regions from low Earth orbit, and they'll work on experiments and projects designed to forward our understanding of long-duration spaceflight. The mission will also mark the first time that crews have used an X-ray machine on humans in orbit.

The Fram2 mission, paid for and led by a cryptocurrency billionaire who is flying with three guests, is on track to return after a journey on a unprecedented polar orbit.
