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

The 80th flight of a SpaceX Falcon 9 rocket delivered 60 more satellites to orbit for the company’s Starlink broadband network Wednesday after launch from Cape Canaveral Air Force Station.

A Russian automated cargo craft loaded with nearly three tons of fuel, supplies, water and air is set for launch from Kazakhstan at 2141 GMT Saturday on a mission to replenish stockpiles aboard the International Space Station.

The launch next year of a commercial communications craft jointly managed by London-based Inmarsat and the Greek satellite operator Hellas-Sat has been switched from SpaceX’s Falcon Heavy to Arianespace’s Ariane 5 rocket, officials said Thursday.
