Time-lapse video: The Falcon Heavy goes vertical again

Keith Gendreau, an astrophysicist at NASA’s Goddard Space Flight Center, recently spoke with Spaceflight Now about a new experiment on the International Space Station to demonstrate X-ray communications in space for the first time.

The crew spent 197 days docked at the ISS and welcomed seven visiting vehicles while on orbit. Splashdown off the coast of Florida is anticipated around 5:50 a.m. EDT on Tuesday, March 12.

SpaceX’s Falcon 9 booster is set for liftoff from Cape Canaveral on Sunday morning, but most of the launcher’s ascent into orbit will be under a news blackout at the request of the National Reconnaissance Office, the secretive U.S. government intelligence agency whose mission is riding on the rocket.
