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

NASA expects to spend some $5 billion underwriting development of commercial spacecraft built by Boeing and SpaceX to carry astronauts to and from the space station, ending reliance on the Russians for crew flights and lowering the average cost per seat to around $58 million.

The mission marked the first time that an American-made rocket launched Europe’s answer to the GPS satellite constellation. Liftoff from Launch Complex 39A happened at 8:34 p.m. EDT (0034 UTC) on Saturday, April 27.

SpaceX launched its fifth Falcon 9 rocket in 22 days on Saturday, beginning a mission to deploy 52 more Starlink internet satellites and two rideshare payloads for Capella Space and Tyvak Nano-Satellite Systems. Liftoff from pad 39A at NASA’s Kennedy Space Center in Florida occurred at 6:56 p.m. EDT (2256 GMT), and SpaceX successfully landed the first stage on a drone ship in the Atlantic Ocean.
