Q&A with Keith Gendreau, principal investigator of the first X-ray space communications experiment (members only)

Watch as SpaceX test fires a Falcon 9 rocket ahead of the planned launch of 60 more Starlink satellites.

The mission was the 30th Starlink launch of the year for SpaceX. Liftoff from pad 40 at Cape Canaveral Space Force Station happened on Thursday, April 24, at 9:52 p.m. EDT (0152 UTC).

SpaceX test-fired a Falcon 9 rocket for the second time Saturday after replacing a valve following an earlier static fire test Wednesday. The move has postponed the Falcon 9 rocket’s launch with the Amos 17 commercial communications satellite to no earlier than Tuesday.
