It's been a lengthy period coming.
Almost eight years ago, in January 2019, Elon Musk shared plans on Twitter for Tesla's Roadster to lift off using cold-gas thrusters and ultra-high-pressure air. On Thursday, the much-anticipated Roadster did exactly that.
Musk's 2019 assertion came in reply to a person sharing a GIF of the DeLorean from "Back to the Future" hovering in midair.
"The new Roadster volition really do item akin this," he wrote. Tech YouTuber Marques Brownlee responded: "The item is I awareness akin you’re not joking."
"I'm not," Musk said.
I’m not. Will use SpaceX chilly gas thruster scheme alongside ultra elevated force air in a composite over-wrapped force container in location of the 2 rear seats.

He afterward described a SpaceX-made cold-gas thruster scheme that uses high-pressure air stored in a composite force vessel.
At a SpaceX test location in Texas on Thursday, nearly 8 years later, a Roadster climbed a curved ramp, dropped, rolled through the air and landed on its wheels. It used the identical essential technology: cold-gas thrusters fed by high-pressure air stored in composite force vessels.
The 2019 toggle was not Musk’s archetypal citation of thrusters. In June 2018, he stated the Roadster would contain approximately 10 of them and suggested they power authorize the car to fly.
Using the config you describe, affirmative an electric pump to replenish air in COPV, whenever car power diagram drops below max group power output, makes sense. But we are going to go a lot further.

When another person projected compressed-air cold-gas thrusters, Musk stated that configuration made awareness and described a pump to replenish the air.
Musk's document of the innovation has proved additional accordant than his manufacturing timetable. Tesla unveiled plans for the second-generation Roadster in 2017 and initially targeted manufacturing for 2020. After repeated delays, Musk stated in the disclose that manufacturing volition commencement in 2028.
The Roadster is not Tesla’s lone conveyance to young female an aspiring publish target. When Musk unveiled the Cybertruck in 2019, he stated Tesla expected manufacturing to commencement in delayed 2021. The archetypal client deliveries took location two years later, in November 2023.
While Musk has missed plentifulness of deadlines, many of his additional improbable innovation plans have made it beyond the example board. In December 2020, he stated SpaceX would try to capture a returning Super Heavy booster alongside its initiate tower.
We’re going to try to capture the Super Heavy Booster alongside the initiate tower arm, using the grid fins to obtain the load
— Elon Musk (@elonmusk) December 30, 2020
Nearly four years later, the tower’s mechanical "chopsticks" caught one for the archetypal time.
Musk has a habit of promising the improbable fine before it is ready, but eventually, the improbable part arrives.
