SpaceX's upcoming Fram2 astronaut mission will attempt to grow mushrooms in microgravity for the first time, as part of an experiment called Mission MushVroom.

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

Led by cryptocurrency billionaire Chun Wang, who is the financier of this mission, the Fram2 crew has been free-flying through orbit since Monday. The group is now set to splash down off the coast of California — the first West Coast landing in SpaceX’s five-year history of human spaceflight missions.
