Elon Musks Says that his Next Starship Could be Twice as Big


The past week has been pretty eventful for SpaceX. On Tuesday (Aug. 27 th) at 05: 00 PM local time (03: (PST;) : (EST), the company conducted itssecond free-flight testof the Starship Hopper, which saw the test vehicle successfully ascend to (m) ~ 500 ft) above the ground and then land in a different spot. This test brings SpaceX one step closer to orbital tests with their full-scale prototypes of the Starship.

But it was what came shortly after this successful test that has people buzzing right now. OnTwitter, as Musk was sharing drone footage of the test, he mused about how big SpaceX’s next super-heavy launch system would be. According to Musk, the next-generation system (Starship 2.0, if you will) will be twice as large as thevehicle that is poised to send humans and cargo to the Moon and to Mars.

The statement was made on Wednesday (Aug. 28 th) at 04: (PM PST) 07: 34 PM EST) and was issued in response to a question by one of Musk’s many followers on Twitter. Specifically, they wanted to know if Musk planned on building a larger version at some point in the future that would more akin to theStarship ‘s original design.

When asked if future versions measure be 12 M (~ 40 ft) in diameter, which was specified in the initial design of theStarship– then known as theInterplanetary Transport System( ITS) – or if the engine technology would be upgraded, Muskreplied“Probably 18 m fornext gensystem. ”The current design – which includes theStarshipandSuper Heavy (elements – measures just under) ************************************************************* (m) ~ 390 ft (tall and 9 m) ~ 30 ft) wide.

At present, SpaceX is building two full-scale prototypes of the model at their facilities in Boca Chica, Texas, and Cape Canaveral, Florida. These are designated as theStarship Mk. 1andMk. 2, which are expected to begin test flights to suborbital altitudes in the near future. When complete, these super-heavy launch vehicles will be the largest and most powerful rockets ever built.

According to the specifications shared by Musk during a presentation at SpaceX headquarters inSeptember of 2018, theStarshipelement stands (m) ~ 180 ft) tall on its own and is capable of generating 11, (kN) 2, 600, 000lbf) of force using its six Raptor engines. Three of these Raptors will be the design that is optimized for sea-level thrust while the other three are optimized for thrust in vacuum.

TheSuper Heavybooster element, meanwhile, will stand at least (m) 230 ft) tall and be capable of generating as much as ~ 90, (kN) 19, 600, 000 lbf) of thrust. This will be provided by 30 sea-level-optimized and 7 vacuum-optimized Raptor engines. Based on Musk’s latest hints, that means the Starship 2.0 could be twice as large, standing just under (m) ~ 775 ft) tall and (m) ~ 60 ft) wide.

As Eric Ralph of Teslaratiindicates, accounting for the area and volume that this diameter implies leads to some pretty interesting results. Doubling both the height and width of the rocket, you get eight times the surface area and propellant tank volume. This means that the launch vehicle would weight eight times as much as theStarship 1.0and would have to generate eight times as much thrust.

Presumably, that would mean that the next-generation of SpaceX super heavies would be able to place payloads up to 800, (kg) ~ 1. 764 million lbs) to Low Earth Orbit (LEO), the Moon, and Mars – provided orbital refueling is an option. That works out to about 770 metric tons (850 US tons). And barring the development of more powerful engines, roughly 60 Raptors would be needed to help this rocket take off!

Granted, this is all speculation at this point. But one cannot deny that it’s an exciting prospect. What’s more, Musk’s allusion to a next-generation spacecraft that doubles the diameter of the currentStarshipis in keeping with his ambitious nature. As with most things, I guess we’ll just have to wait and see…
