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

After several delays to wait for improved weather, SpaceX sent a Falcon 9 rocket into space Saturday from California’s Central Coast with 51 small satellites, payloads, and orbital transfer vehicles from customers around the world.

SpaceX launched a prototype Starship rocket Tuesday from its Boca Chica, Texas, flight facility, successfully sending the silver booster up to an altitude of about six miles as planned. But the unpiloted test flight ended with a spectacular explosion when the rocket failed to right itself and slow down enough for a tail-first landing.

SpaceX this week released a new batch of photos showing the Feb. 6 liftoff of the company’s first Falcon Heavy rocket from pad 39A at the Kennedy Space Center in Florida, followed by landing of the launcher’s two side boosters around eight minutes later at nearby Cape Canaveral Air Force Station.
