4K Video: The launch of Crew 4 as seen from the press site

The launch will be preceded by a company talk from Elon Musk, discussing SpaceX’s plans for developing the rocket for Mars exploration. Launch teams are targeting a liftoff from Pad A at Starbase, Texas, on Tuesday, May 27, at 6:30 p.m. CDT (7:30 p.m. EDT, 2330 UTC).

The mission, dubbed Maxar 3 by SpaceX, was the third launch of Maxar’s WorldView Legion satellites. Liftoff from Launch Complex 39A happened at 6:13 p.m. EST (2313 UTC).

Astronauts will not fly to the International Space Station on SpaceX’s Crew Dragon spaceship until at least May 2018, NASA said this week, missing a previous target launch date at the end of next year.
