Three years ago, the idea of flying 37 engines on a single rocket seemed fanciful. And then, in early 2018, the company launched with Falcon Heavy with 27 engines. Three years ago, the notion of landing and re-flying a large rocket multiple times seemed distant. But now SpaceX has done this dozens of times.
But most futuristic of all seemed the notion of a 50-meter tall spaceship that could launch into space, fly on to the Moon or Mars, and return to Earth. And yet this was what Musk put on display with the Starship Mk 1 vehicle.
Seated alongside the company's principal Mars development engineer, Paul Wooster, Musk expounded upon his timeline for going to the Moon and Mars.
"It depends on whether development remains exponential. If it remains exponential, it could be like two years," Musk said of landing on the Moon. A cargo trip to Mars could happen by 2022, due to the availability of launch windows, he added. "I mean these are just total guesses, as opposed to checking a train schedule."
