Q&A with Elon Musk after SpaceX’s first rocket landing

Returning to port late Thursday under the cover of darkness, SpaceX’s rocket recovery platform has moored at a dock in Jacksonville, Florida, for unloading of charred debris from Tuesday’s crash landing of a Falcon 9 booster.

SpaceX could use its Starship vehicles to clear out space debris in Earth orbit, alongside the program’s more publicized purpose of ferrying people and cargo to the moon and Mars, a company executive said.

NASA officials say the International Space Station’s logistics chain was designed to absorb a launch failure like the mishap that destroyed an Orbital Sciences Corp. cargo craft in October, but pressure is on SpaceX to deliver supplies on time this year.
