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

In this time-lapse video, the Falcon 9 rocket with the Crew Dragon atop rolls to launch pad 39A at the Kennedy Space Center for the first time on January 3. The rocket was then lifted vertical for a series of fit checks and tests.

The European-built Solar Orbiter spacecraft arrived in Florida late Friday after a trans-Atlantic journey from a test center in Germany, ready to begin preparations for a liftoff from Cape Canaveral in February aboard a United Launch Alliance Atlas 5 rocket.

SpaceX will attempt to land its 470th Falcon booster during the Starlink 15-7 mission. It’s targeting liftoff from pad 4E at 10:13 a.m. PDT (1:13 p.m. EDT, 1713 UTC) on Saturday, June 28.
