Live coverage: H-2A rocket delivers on 30th flight

SpaceX launched a Falcon 9 rocket from Vandenberg Space Force Base, California, with 51 small satellites, hosted payloads, and orbital transfer vehicles heading into polar orbit on the Transporter 7 mission. Liftoff occurred at 11:48 p.m. PDT Friday (2:48 a.m. EDT; 0648 UTC Saturday).

Extra testing of the James Webb Space Telescope and delays in assembling the powerful observatory will push back the $10 billion mission’s launch by at least six months to early 2019, officials announced last week as the telescope successfully completed an extensive performance test inside a cryogenic vacuum chamber in Houston.

A Japanese H-2A rocket launched the fourth satellite for the country’s regional navigation network Monday. Liftoff from the Tanegashima Space Center in southwestern Japan occurred at 2201:37 GMT (6:01:37 p.m. EDT).
