The launch will be the first human spaceflight mission to a polar orbit. Liftoff is set for Monday, March 31, at 9:46 p.m. EDT (0146 UTC).

United Launch Alliance’s final Delta 2 rocket is now on display at the Kennedy Space Center Visitor Complex in Florida, a monument to an industry workhorse that helped build the GPS navigation satellite fleet and enabled a new era of Mars exploration.

Bigelow Space Operations says it will charge $52 million per seat to send private astronauts to the International Space Station aboard Crew Dragon ferry ships, and has already paid “substantial sums” to SpaceX for up to four dedicated crew missions to the orbiting research complex.
