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

Rocket Lab’s Electron launcher delivered two all-weather radar Earth observation satellites into orbit for Capella Space Thursday night after liftoff from Wallops Island, Virginia, successfully completing the company’s second flight from the U.S. spaceport.

These photos show the 215-foot-tall Falcon 9 rocket and Crew Dragon spacecraft at launch pad 39A, ready for liftoff from Florida’s Space Coast on a critical test flight to the International Space Station.

Mostly clear skies and brisk westerly winds are forecast at launch time Friday afternoon for SpaceX’s first resupply mission to the International Space Station in nearly a year.
