The goal of this mission, lasting up to five days in orbit, is to fly higher than previous Dragon missions, perform the first-ever commercial EVA with SpaceX-designed spacesuits, orbit through portions of the Van Allen radiation belt, conduct medical research, and test laser-based Starlink communications in space.
