Elon Musk's Tesla Roadster

Image
Elon Musk's Tesla Roadster is an electric sports car that served as the dummy payload for the February 2018 Falcon Heavy test flight and became an artificial satellite of the Sun. "Starman", a mannequin dressed in a spacesuit, occupies the driver's seat. The car and rocket are products of Tesla and SpaceX, respectively, both companies headed by Elon Musk. The 2008-model Roadster is personally owned by and previously used by Musk for commuting to work. It is the first production car launched into space and first to orbit the sun. The car, mounted on the rocket's second stage, acquired enough velocity to escape Earth's gravity and enter an elliptical heliocentric orbit crossing the orbit of Mars. The orbit reaches a maximum distance from the Sun at aphelion of 1.66 astronomical units (au) . During the early portion of the voyage outside the Earth's atmosphere, live video was transmitted back to the mission control center and live-streamed for slightly ove...

Background

In March 2017, SpaceX's founder, Elon Musk, said that because the launch of the new Falcon Heavy vehicle was risky, it would carry the "silliest thing we can imagine". In June 2017, one of his Twitter followers suggested that the silly thing be a Tesla Model S, to which Musk replied "Suggestions welcome!". In December 2017 he announced that the payload would be his personal "midnight cherry Tesla Roadster". Later that month, photos of the car prior to payload encapsulation were released. One of the test flight objectives was to demonstrate that the new rocket could carry a payload as far as the orbit of Mars. NASA had declined SpaceX's offer to carry a scientific payload. Following the successful launch, the Roadster became the first standard roadworthy vehicle sent into space, though several special-purpose lunar and Mars rovers had previously been launched.

Trajectory

Image
The US Office of Commercial Space Transportation issued the test flight's launch license on February 2, 2018. The rocket lifted off from Launch Complex 39A at Kennedy Space Center at 15:45 EST (20:45 UTC) on February 6. The upper stage supporting the car was initially placed in an Earth parking orbit. It spent six hours coasting through the Van Allen radiation belts, thereby demonstrating a new capability requested by the U.S. Air Force for direct insertion of heavy intelligence satellites into geostationary orbit. Then, the upper stage performed a second boost to reach the desired escape trajectory. The launch was live streamed, and video feeds from space showed the Roadster at various angles, with Earth in the background, thanks to cameras placed inside and outside the car, on booms attached to the vehicle's custom adaptor atop the upper stage. Musk had estimated the car's battery would last over 12 hours, but the live stream ran for just over four hours, thus ending befo...

Cultural impact

The car in space quickly became a topic for Internet memes. Western Australia Police distributed a picture of a radar gun aimed at the Roadster whilst above Australia. Škoda produced a parody video of a Škoda Superb being driven to Mars (a village in central France). An attempt was made by Donut Media to launch a Hot Wheels Tesla Model X to the stratosphere using a weather balloon. ToSky, a Siberian start-up, sent a scale model of a Soviet-era Lada carrying a mannequin of Roscosmos head Dmitry Rogozin to an altitude of 20 km to gather test data for the design of stratostats. Some news reports observed a similarity between the real pictures of a car orbiting the Earth and the title sequence of the 1981 animation film Heavy Metal , where a space traveler lands on Earth in a two-seater Chevrolet Corvette convertible. The SpaceX launch live stream reached over 2.3 million concurrent viewers on YouTube, which made it the second most watched live event on the platform, behind another space-r...

Reactions

The choice of the Roadster as a dummy payload was variously interpreted as marketing for Tesla, or a work of art, with some worrying about the risk to contamination of otherwise sterile solar system bodies. Some also commented on how the Roadster was not a space debris risk. Marketing edit Musk was lauded as a visionary marketer and brand manager by controlling both the timing and the content of his corporate public relations. After the launch, Scientific American said using a car was not entirely pointless, in the sense that something of that size and weight was necessary for a meaningful test. "Thematically, it was a perfect fit" to use the Tesla car, and there was no reason not to take the opportunity to remind the auto industry that Musk was challenging the status quo in that arena, as well as in space. Advertising Age agreed with Business Insider that the Roadster space launch was the "greatest ever car commercial without a dime spent on advertising", demons...

Orbit tracking

Image
The car and the upper stage were passivated by intentionally removing remaining chemical and electrical energy, at which point they ceased transmitting telemetry. Based on optical observations made using a robotic telescope at the Warrumbungle Observatory, Dubbo, Australia and refinement of the orbit, a close re-encounter with Earth (originally predicted for 2073) is not possible. In October 2020 the car made a close approach to Mars, about 8 million kilometres (5 million miles) away, well outside the planet's gravitational sphere of influence. The Virtual Telescope Project observed the Tesla two days after its launch, where it had a magnitude of 15.5, comparable to Pluto's moon Charon. The Roadster was automatically spotted and logged by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope operated by the University of Hawaii. The car was observed by the Deimos Sky Survey (DeSS) at a distance of 720,000 km (450,000 mi) with a flashing effect suggesting spinning....
