Massive, AI-powered robots are 3D-printing entire rockets


To make a 3D-printable rocket, Relativity Space simplified the design of many components, including the engine.PHOTOGRAPH: RELATIVITY

Relativity Space may have the biggest metal 3D printers in the world, and they’re cranking out parts to reinvent the rocket industry here—and on Mars.

For a factory where robots toil around the clock to build a rocket with almost no human labor, the sound of grunts echoing across the parking lot make for a jarring contrast.

“That’s Keanu Reeves’ stunt gym,” says Tim Ellis, the chief executive and cofounder of Relativity Space, a startup that wants to combine 3D printing and artificial intelligence to do for the rocket what Henry Ford did for the automobile. As we walk among the robots occupying Relativity’s factory, he points out the just-completed upper stage of the company’s rocket, which will soon be shipped to Mississippi for its first tests. Across the way, he says, gesturing to the outside world, is a recording studio run by Snoop Dogg.

Neither of those A-listers have paid a visit to Relativity’s rocket factory, but the presence of these unlikely neighbors seems to underscore the company’s main talking point: It can make rockets anywhere. In an ideal cosmos, though, its neighbors will be even more alien than Snoop Dogg. Relativity wants to not just build rockets, but to build them on Mars. How exactly? The answer, says Ellis, is robots—lots of them.

Spacecraft To Test Einstein’s Theory Of Relativity

Does E really equal mc squared?
In what is billed to be the largest scientific instrument ever built, scientists plan to use three spacecraft flying three million miles apart to fire laser beams at each other across the emptiness of space in a bid to finally prove whether a theory proposed by Albert Einstein is correct.

Physicists hope the ambitious mission will allow them to prove the existence of gravitational waves — a phenomenon predicted in Einstein’s famous theory of general relativity and the last piece of his theory still to be proved correct, reports the Telegraph…
