SpaceX founder Elon Musk detailed progress on the company’s next-generation Starship program Monday, saying the huge rocket could “probably” attempt its first launch into Earth orbit next year, and adding that the Starship will fly hundreds of missions before SpaceX puts people on-board.

Packed with food, hardware and experiments in biology, Earth science and space technology, a Falcon 9 rocket and Dragon supply ship lifted off Monday from Cape Canaveral destined for the International Space Station.

SpaceX called off a launch attempt in Texas Monday for the Super Heavy booster and Starship launch vehicle, blaming a bad valve on the first stage. The next launch attempt for the world’s largest rocket is scheduled for Thursday, depending on weather and a fix for the valve problem.
