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

Tuesday is shaping up to be a busy day for SpaceX, with liftoff of a Falcon 9 rocket carrying a space weather satellite, an experimental booster flyback maneuver to test reusable launch technologies, and the splashdown of a Dragon capsule returning from the International Space Station.

Returning to port late Thursday under the cover of darkness, SpaceX’s rocket recovery platform has moored at a dock in Jacksonville, Florida, for unloading of charred debris from Tuesday’s crash landing of a Falcon 9 booster.

NASA officials said Thursday the launch of the James Webb Space Telescope will be delayed seven months to Oct. 31, 2021, a schedule slip that takes into account work slowdowns caused by the coronavirus pandemic and the amount of testing required on the observatory before its shipment to French Guiana for liftoff on a European Ariane 5 rocket.
