The billionaire CEO of SpaceX hosted a press conference after the company's Falcon Heavy rocket aced its first launch Tuesday.
Starman and the Roadster are on their way to the asteroid belt and could meander through deep space for billions of years.
"We want a new space race", Musk said.
It sounds like an ambitious project, but what's new when it comes to Tesla and Elon Musk.
"There is a part of the commercial market that requires Falcon Heavy", SpaceX president Gwynne Shotwell told the Los Angeles Times past year.
"I think the new architecture, the BFR architecture, is the way to go", he said. "It's still tripping me out". The original plan had the vehicle traveling only as far as Mars, coming close to the red planet but hopefully not nicking it. Musk's tweet sounds like the Tesla is approaching the asteroid belt, but it's not. It went to the International Space Station aboard the Space Shuttle Discovery in early 2011. "Awesome! At this speed, two hands on the steering wheel please (hash) Starman".
SpaceX has not released the orbital parameters of the Tesla, but it is now being tracked along with thousands of other space objects by the U.S. Air Force Space Command.
Mars is driving all of Musk's space efforts.
A flat-earther who witnessed this week's SpaceX launch says it was a hoax - and that Elon Musk has been "groomed" to help fool people into thinking intergalactic travel is possible. SpaceX successfully landed the two side boosters back at Kennedy Space Center minutes after launch. Musk warned that spending would increase slightly this year.
Since Tesla wants to build a system that's more generally useful, it made sense for the company to not push ahead with this a year ago and try to do it probably.
NASA's marketing of how many elephants, locomotives and airplanes could be launched by various versions of SLS is a ideal example of the frivolity of developing, building and operating their own rocket.
BFR would eventually replace SpaceX's Falcon 9 and Falcon Heavy rockets and the Dragon capsule.
The president of the Mars Society, a space advocacy group intent on exploring and settling Mars, cheered SpaceX's achievement _ and reduced price. "The naysayers have been completely refuted".
The upshot is that there's something phony about talk of a Tesla-SpaceX merger - because it's really already happened, optically.
Musk revealed his most recent plan at a conference in Australia past year.
Well, a lot more flights of the Falcon Heavy, for one.
