Watch Live! SpaceX's Fram2 astronaut mission return to Earth

Fram2 launched atop a Falcon 9 rocket from NASA's Kennedy Space Center in Florida on Monday night (March 31), sending four spaceflight rookies to orbit.

That quartet is Maltese cryptocurrency billionaire Chun Wang, who funded and commands Fram2; vehicle commander Jannicke Mikkelsen of Norway; pilot Rabea Rogge of Germany; and Australian Eric Philips, mission specialist and medical officer.

Fram2 has been conducting 22 science experiments as it circles Earth, including one called MushVroom, which is attempting to grow mushrooms in orbit for the first time.
