How Elon Musk’s Starship Timeline Has Changed Over Seven Years

As large as Starship is, it was initially going to be larger.

In 2016, Elon Musk was dropping hints of a large new spacecraft that might take individuals — a lot of them — to Mars. He known as it the Mars Colonial Transporter.

By the time he unveiled the design on the International Astronautical Congress in Guadalajara, Mexico, the identify had modified to a blander one: Interplanetary Transport System. It was gargantuan.

The booster, 40 ft in diameter and 254 ft tall, can be powered by 42 Raptor engines. The spaceship half was even wider, practically 56 ft, as a part of its design for gliding by means of atmospheres throughout re-entry.

Mr. Musk highlighted high-tech carbon composite fibers that might be used for a lot of the construction.

Inside, it will be roomy sufficient for 100 settlers heading to Mars for a brand new life on a brand new planet.

“What you noticed there’s very near what we’ll truly construct,” Mr. Musk mentioned then, referring to the rockets and spacecraft he had simply described.

Actually not.

A yr later, the design had slimmed down by 25 p.c, to 30 ft. The identify modified, too, to BFR (The “B” stood for “large,” the “R” for “rocket,” and Mr. Musk by no means publicly acknowledged what the “F” stood for. Gwynne Shotwell, the president of SpaceX , gamely and unconvincingly asserted that “F” stood for “Falcon,” a nod to SpaceX’s present Falcon 9 rockets.)

The smaller dimension would make it extra sensible for launching satellites, accumulating particles from low-Earth orbit and making fast suborbital hops world wide for rich vacationers in a rush.

Details of the design shifted repeatedly. Landing legs had been changed by fins that doubled as touchdown legs. Then separate touchdown legs returned.

Mr. Musk jettisoned the carbon fiber composites and determined to make the spacecraft out of chrome steel as a substitute. Steel is less expensive and simpler to work with, he mentioned.

The identify modified once more, from BFR to Starship.

By the time SpaceX began conducting high-altitude hops of Starship prototypes in 2020, the form of the spacecraft had largely settled to what’s now on the launchpad.

While the unique Interplanetary Transport System seemed sleekly futuristic — one thing that might have match effectively with the aesthetic of “2001: A Space Odyssey” — Starship has developed into an easier, shinier form that’s nearly retro, reminiscent of Buck Rogers and different mid -Twentieth century sci-fi visions of the upcoming house age.

As the identify and design have modified, so have Mr. Musk’s overly optimistic predictions for when his spaceship would get to Mars. At Guadalajara, he mentioned the primary flight of the Interplanetary Transport System to Mars, carrying cargo however not individuals, would take off in 2022 and that the primary flight with individuals might launch in 2024.

Needless to say, nobody is packing luggage for a visit to Mars subsequent yr.

At an occasion in Boca Chica, Texas, in September 2019, Mr. Musk, standing in entrance of a shiny, chrome steel Starship prototype, proclaimed that an orbital check flight might happen inside six months and that it was conceivable {that a} flight carrying individuals might take off someday later in 2020.

That check flight of Starship and the Super Heavy booster initially promised for early 2020 would possibly lastly take off.

A Starship flight with individuals aboard stays additional sooner or later.
