It will use its stubby fins for control, “rather like how skydivers use their hands and feet”, says Scott Manley, a physicist and programmer who runs a popular rocketry-focused YouTube channel. Starship will fall belly-first from space, relying on atmospheric drag to shed most of its speed. Recovering the upper stage requires more drama. SpaceX plans to catch it in mid-air with a pair of robotic “chopsticks” attached to the launch tower from which it took off. Its Super Heavy first stage, like the Falcon 9’s, is designed to fly back to the ground shortly after launch. With Starship, SpaceX plans to recover both parts. But their second stages, which end up much higher and moving at orbital speeds, remain expendable. Once refurbished and refuelled, they can fly again, spreading their construction cost over many launches. SpaceX already flies partially reusable rockets: the first stages of its Falcon 9 machines fly back to Earth under their own power. But all versions had one thing in common: they are designed to be entirely reusable. Earlier versions were huger still: the ITS had a 300-tonne payload at one point. Something like Starship has been in development at SpaceX for over a decade, under names such as MCT (Mars Colonial Transporter), ITS (Interplanetary Transport System), and BFR (Big Fucking Rocket). An orbital flight, he said, might come in “a couple of months”-though it could also slip to the end of the year. In his press conference, Mr Musk left himself a fair amount of wriggle room. An internal memo leaked last year revealed serious problems with the Raptor engines intended to power Starship. But broader environmental issues could yet force the firm to suspend work at Boca Chica entirely. Officials have promised a decision within weeks. That orbital flight, though, needs approval from regulators, who were deluged with thousands of public comments.

A full-fledged orbital test of the two-stage form of the rocket, with one Starship upper stage sitting atop a Super Heavy booster, had been due in January. A successful flight came on May 5th last year, when an upper stage flew 10km into the air before landing safely back on its pad.

A series of test flights of Starship’s upper stage (which, in isolation, is rather confusingly also called “Starship”) have ended in crash-landings and explosions. And Starship is vital to the future of SpaceX itself, which was valued recently at more than $100bn (see chart 2).īut first the rocket needs to fly. NASA intends to use it to land astronauts on the Moon America’s soldiers are eyeing it up, too.

Some scientists are already imagining extravagant space missions that would make full use of the rocket’s huge capacity. An industry used to shaving grams of mass and cramming complicated payloads into small cargo bays will see those restrictions lifted. But Starship’s unprecedented combination of size and frugality could upend the economics of the space business closer to Earth, too. Mars colonies, if they ever come, remain a long way off. Despite Starship’s size, SpaceX hopes to cut that to the low millions. Existing rockets cost tens to hundreds of millions of dollars per launch (the Saturn V may have cost over $1bn in today’s money). To that end, it is designed to be not only the biggest rocket ever built, but also the cheapest. Starship is designed to transport the million tonnes of supplies he thinks is needed for that job-roughly 100 times more mass than has been launched since the start of the Space Age. With Starship, the idea is that all the hardware will come back: the massive booster stage almost immediately, the second, orbital stage after fulfilling whatever mission it had been sent on.Īt a press event on February 10th to show off an assembled rocket Mr Musk reiterated his reasons for founding SpaceX: to buy humanity an insurance policy against existential risks by establishing a colony on Mars. When a Saturn V took off to send men to the Moon, the only bit of the 2,800 tonnes of hardware which came back was a cramped five-tonne capsule with three men inside. But it is not just the size that matters.
