Q&A with Elon Musk, founder and CEO of SpaceX (members only)

NASA announced Friday a mix of spaceflight veterans and rookie astronauts who will launch on the first flights of new Boeing and SpaceX commercial spaceships starting as soon as next spring, several months later than previously scheduled.

Sixty more satellites for SpaceX’s Starlink broadband network launched Monday on a Falcon 9 rocket from Cape Canaveral, bringing the total number of Starlink platforms deployed in orbit since last May to 300.

A work stoppage at the Ariane 5 rocket’s launch base in South America prevented rollout of the booster to the launch pad Monday, pushing back the liftoff of two communications satellites for Brazil and South Korea until at least Wednesday.
