Video: NASA and SpaceX brief media on space station cargo flight

The four-member crew will now fly onboard Dragon Endurance instead of SpaceX’s fifth Crew Dragon spacecraft as originally intended. Launch has moved up to Wednesday, March 12, “pending mission readiness and completion of the agency’s certification of flight readiness process.”

The mission comes on the heels of SpaceX having to stand down from launching the Polaris Dawn astronaut mission due to weather concerns. The lost booster, tail number B1062, was aiming for a record 23rd landing on the droneship ‘A Shortfall of Gravitas’ when it collapsed and exploded.

Five Earth-imaging spacecraft for the Peruvian government and Google’s Terra Bella satellite subsidiary are enclosed inside the nose cone of a Vega rocket for liftoff Thursday from French Guiana.
