Q&A with Elon Musk, SpaceX’s founder and CEO

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a two-day pursuit of the International Space Station.

A SpaceX Falcon 9 rocket is set for launch from Kennedy Space Center in Florida on Monday with a mobile broadband communications satellite for Inmarsat.

After completing a countdown dress rehearsal, Astra is gearing up for its first orbital launch attempt this week from Kodiak Island, Alaska, but company officials said it will likely take multiple test flights before the new small satellite launcher successfully reaches orbit.
