Q&A with Martin Halliwell, chief technology officer at SES

A commercial Dragon cargo craft launched June 29 departed the International Space Station and returned to Earth on Friday with nearly two tons of cargo and research samples.

Rookie astronaut Raja Chari — a former U.S. Air Force fighter pilot — veteran physician-astronaut Tom Marshburn, and European Space Agency astronaut Matthias Maurer have been assigned to fly to the International Space Station on a SpaceX Crew Dragon spaceship in the fall of 2021.

SpaceX has delayed liftoff of its next cargo ship bound for the International Space Station until Friday, setting up a one-shot attempt to launch the commercial supply carrier from Cape Canaveral before a potential slip to late December due to high solar angles in orbit.
