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

SpaceX is targeting April 8 for the launch of its first resupply run to the International Space Station in nearly a year, a mission that the company hopes will mark the start of a rapid-fire launch manifest full of payloads waiting to fly.

NASA is moving forward with a crucial test-firing of the core stage of the first Space Launch System heavy-lift rocket as soon as Jan. 17 after engineers were satisfied with the results of a fueling test last month.

A recent federal regulatory filing by SpaceX suggests the company may attempt to return a Falcon 9 rocket booster to Vandenberg Air Force Base in California for the first time later this year.
