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. A mannequin in a spacesuit, dubbed "Starman", occupies the driver's seat. The car and rocket are products of Tesla and SpaceX, respectively, both companies headed by Elon Musk.{{cite news |url=https://www.cnet.com/news/tesla-motors-founders-now-there-are-five/ |title=Tesla Motors founders: Now there are five |work=CNet |first=Martin |last=LaMonica |date=September 21, 2009 |access-date=September 18, 2018 |quote=agreed-upon "founders" of Tesla.

It is the first production car launched into space.

The car, mounted on the rocket's second stage, was launched on an escape trajectory and entered an elliptical heliocentric orbit crossing the orbit of Mars.{{cite news|url=https://spaceflightnow.com/2018/02/08/starman-puts-earth-in-the-rearview-mirror/|title='Starman' puts Earth in the rearview mirror|first=William|last=Harwood|via=Spaceflight Now|work=CBS News|date=February 8, 2017|access-date=February 8, 2018|archive-date=November 9, 2020|archive-url=https://web.archive.org/web/20201109062817/https://spaceflightnow.com/2018/02/08/starman-puts-earth-in-the-rearview-mirror/|url-status=live}} The orbit reaches a maximum distance from the Sun at aphelion of 1.66 astronomical units (au). Video of the Roadster during the launch was transmitted back to the mission control center and live-streamed.

Advertising analysts noted Musk's sense of brand management and use of new media for his decision to launch a Tesla into space. Musk explained he wanted to inspire the public about the "possibility of something new happening in space" as part of his larger vision for spreading humanity to other planets.

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".{{cite tweet |user=elonmusk |author-link=Elon Musk |number=847884351375372288 |title=Silliest thing we can imagine!

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 deputy administrator Lori Garver stated that SpaceX had "offered free launches to NASA, Air Force etc. but got no takers", and that "the Tesla gimmick was the backup".{{Cite web |title=Launching Elon Musk's car toward Mars was a backup plan — here's what SpaceX actually wanted to do with Falcon Heavy's first flight |first=Dave |last=Mosher |date=February 9, 2018 |url=http://www.businessinsider.com/starman-tesla-backup-payload-spacex-musk-nasa-2018-2 |website=Business Insider |access-date=February 9, 2018 |archive-date=November 9, 2020 |archive-url=https://web.archive.org/web/20201109025228/https://www.businessinsider.com/starman-tesla-backup-payload-spacex-musk-nasa-2018-2?r=DE&IR=T |url-status=live }}

The Roadster is in a heliocentric orbit that crosses the orbit of Mars and reaches a distance of {{nowrap|1.66 au}} from the Sun. With an inclination of roughly 1 degree to the ecliptic plane, compared to Mars' 1.85° inclination, this trajectory by design cannot intercept Mars, so the car will neither fly by Mars nor enter an orbit around Mars.{{cite web |last1=Plait |first1=Phil |title=Elon Musk: On the Roadster to Mars |url=http://www.syfy.com/syfywire/elon-musk-on-the-roadster-to-mars |website=Syfy Wire |access-date=December 7, 2017 |date=2017-12-02 |archive-date=January 29, 2021 |archive-url=https://web.archive.org/web/20210129185324/https://www.syfy.com/syfywire/elon-musk-on-the-roadster-to-mars |url-status=live }} This was the second object launched by SpaceX to leave Earth orbit, after the DSCOVR mission to the Earth–Sun {{L1}} Lagrangian point.

Even if the rocket had targeted an actual Mars transfer orbit, the car could not have been placed into orbit around Mars, because the upper stage that carries it is not equipped with the necessary propellant, maneuvering, and communications capabilities. This flight simply demonstrated that Falcon Heavy is capable of launching significant payloads towards Mars in potential future missions.

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.

Advertising Age agreed with Business Insider that the Roadster space launch was the "greatest ever car commercial without a dime spent on advertising", demonstrating that Musk is "miles ahead of the rest" in reaching young consumers, where "mere mortals scrabble about spending millions to fight each other over seconds of air time", Musk "just executes his vision." Alex Hern, technology reporter for The Guardian, said the choice to launch a car was a "hybrid of genuine breakthrough and nerd-baiting publicity stunt" without "any real point beyond generating good press pics", which should not detract from the much more important technological milestone represented by the launch of the rocket itself.{{Cite news |last=Hern |first=Alex |date=February 7, 2018 |title=Forget the car in space: why Elon Musk's reusable rockets are more than a publicity stunt; The onboard Tesla Roadster grabbed the headlines, but the real success of this week's space adventure was the Falcon Heavy launch vehicle |url=https://www.theguardian.com/science/shortcuts/2018/feb/07/forget-the-car-in-space-why-elon-musks-reusable-rockets-are-more-than-a-publicity-stunt |url-status=live |archive-url=https://web.archive.org/web/20180207200649/https://www.theguardian.com/science/shortcuts/2018/feb/07/forget-the-car-in-space-why-elon-musks-reusable-rockets-are-more-than-a-publicity-stunt |archive-date=February 7, 2018 |newspaper=The Guardian |issn=0261-3077}}

Lori Garver, a former NASA deputy director, initially said the choice of payload for the Falcon Heavy maiden flight is a gimmick and a loss of opportunity to further advance science—but later clarified that "I was told by a SpaceX VP (vice president) at the launch that they offered free launches to NASA, Air Force etc. but got no takers."{{cite news |url= https://www.standard.co.uk/news/world/spacex-falcon-heavy-launch-nothing-more-than-a-gimmick-says-former-nasa-deputy-administrator-lori-a3762376.html |title= Elon Musk's SpaceX Falcon Heavy launch was just a gimmick, says former NASA boss Lori Garver |newspaper= Evening Standard |first= Alexandra |last= Richards |date= 2018-02-09 |access-date= 2018-02-09 |url-status= live |archive-url= https://web.archive.org/web/20180209194810/https://www.standard.co.uk/news/world/spacex-falcon-heavy-launch-nothing-more-than-a-gimmick-says-former-nasa-deputy-administrator-lori-a3762376.html |archive-date= February 9, 2018 |df= mdy-all }}

Alice Gorman, a lecturer in archaeology and space studies at Flinders University in Australia, said that the Roadster's primary purpose is symbolic communication, that "the red sports car symbolises masculinity – power, wealth and speed{{Cite web |last=David |first=Leonard |date=2018-02-09 |title=Tesla Roadster Gets Interplanetary ID |url=https://www.space.com/39646-tesla-roadster-gets-interplanetary-id.html |url-status=live |archive-url=https://web.archive.org/web/20180220092347/https://www.space.com/39646-tesla-roadster-gets-interplanetary-id.html |archive-date=2018-02-20 |access-date= |website=Space.com}} – but also how fragile masculinity is". Drawing on anthropological theories of symbols, she argues that "the car is also an armour against dying, a talisman that quells a profound fear of mortality". Gorman wrote that "the spacesuit is also about death. ...

He added: "The enthusiasm and interest that [Musk] generates more than offsets the infinitesimally small 'littering' of the cosmos."{{Cite web |last=David |first=Leonard |date=2018-02-05 |title=Is the Tesla Roadster Flying on the Falcon Heavy's Maiden Flight Just Space Junk? |url=https://www.space.com/39602-falcon-heavy-tesla-not-just-space-junk.html |url-status=live |archive-url=https://web.archive.org/web/20180206182537/https://www.space.com/39602-falcon-heavy-tesla-not-just-space-junk.html |archive-date=2018-02-06 |access-date= |website=Space.com}} Tommy Sanford, director of the Commercial Spaceflight Federation, said that the car and its rocket stage are no more "space junk" than the mundane material usually launched on other test flights. Mass simulators are often deliberately placed in a graveyard orbit or sent on a deep space trajectory, where they are not a hazard.{{cite web |url=https://mashable.com/2018/02/08/elon-musk-tesla-roadster-not-typical-space-junk/ |title=Elon Musk's 'Starman' Tesla Roadster isn't your typical piece of space junk |first=Mark |last=Kaufman |website=Mashable |date=February 8, 2018 |access-date=February 15, 2018 |archive-date=February 9, 2018 |archive-url=https://web.archive.org/web/20180209085320/https://mashable.com/2018/02/08/elon-musk-tesla-roadster-not-typical-space-junk/ |url-status=live }}

Orbit tracking {{anchor|Astrometry}}

The car and the upper stage were passivated by intentionally removing remaining chemical and electrical energy, at which point they ceased transmitting telemetry. The car was observered by Australian astronomer Peter Starr using a 0.43m Planewave telescope at Dubbo Observatory, NSW. Based on these observations and refinement of the orbit, a close re-encounter with Earth (originally predicted for 2073) is not possible.{{cite web|first1=Marco|last1=Langbroek|first2=Peter|last2=Starr|url=https://sattrackcam.blogspot.co.uk/2018/02/starman-falcon-heavytesla-roadster-2018.html|title=Starman (Falcon Heavy/Tesla Roadster) 2018-017A imaged in Space|date=9 February 2018|access-date=9 February 2018|quote=images were taken, 16:39-16:50 UT on 8 February 2018 [...] distance of 550 000 km or about 1.4 Lunar distances c.q. 0.0037 AU [...] 30-second exposures taken by Peter Starr and me with the 0.43-m F6.8 remote robotic telescope of Dubbo Observatory in Australia [...] 2073 close encounter [...] is no longer on the table.|archive-date=February 10, 2018|archive-url=https://web.archive.org/web/20180210065005/https://sattrackcam.blogspot.co.uk/2018/02/starman-falcon-heavytesla-roadster-2018.html|url-status=live}} In October 2020 the car made a close approach to Mars, about {{convert|5|e6mi|sigfig=1|order=flip|abbr=off}} away, at which distance Mars's gravity had no significant effect on the Roadster's orbit.{{cite news |url=https://www.cnn.com/2020/10/08/cars/spacex-tesla-mars-starman-scn-trnd/index.html |title=SpaceX's Tesla roadster made its first close approach with Mars |work=CNN |first=Allen |last=Kim |date=October 8, 2020 |access-date=April 26, 2022 |archive-url=https://web.archive.org/web/20201126031149/https://www.cnn.com/2020/10/08/cars/spacex-tesla-mars-starman-scn-trnd/index.html |archive-date=2020-11-26 |url-status=live}}

Through measuring changes in apparent brightness of the object, astronomers have determined that the Roadster is rotating with a period of 4.7589 ± 0.0060 minutes (i.e. 4 minutes, 46 seconds).{{cite web|url=https://www.popularmechanics.com/space/satellites/a17762760/heres-exactly-how-fast-elon-musks-tesla-is-spinning-in-space/|title=Here's Exactly How Fast Elon Musk's Tesla Is Spinning In Space|date=February 13, 2018|access-date=February 13, 2018|archive-date=February 14, 2018|archive-url=https://web.archive.org/web/20180214014740/https://www.popularmechanics.com/space/satellites/a17762760/heres-exactly-how-fast-elon-musks-tesla-is-spinning-in-space/|url-status=live}} By February 11, 2018, astrometry measurements from 241 independent observations had been collated, refining the positions to within one-tenth of an arcsecond and published by the SeeSat-L mailing list, a group of amateur satellite spotters—more accurate than for most observations of objects in space.{{cite web|url=http://www.satobs.org/seesat/Feb-2018/0117.html|title=Re: Tesla roadster and booster observations|first=Bill|last=Gray|date=2018-02-11|via=SeeSat-L mailing list|quote=list of 241 observations and growing [...] continue to be observed for about two weeks.

= Predictions =

The roadster made its first close approach to Mars on October 7, 2020. The next close approach to Earth will be in the year 2047 at a distance of 5 million kilometers, about 13 times the distance between Earth and the Moon. Simulations over a 3-million-year timespan found a probability of the Roadster colliding with Earth at approximately 6%, or with Venus at approximately 2.5%. These probabilities of collision are similar to those of other near-Earth objects. The half-life for the tested orbits was calculated as approximately 20 million years, but with trajectories varying significantly following a close approach to the Earth–Moon system in 2091.{{cite journal|last1=Rein|first1=Hanno|last2=Tamayo|first2=Daniel|last3=Vokrouhlicky|first3=David|title=The random walk of cars and their collision probabilities with planets|journal=Aerospace|volume=5|issue=2|pages=57|arxiv=1802.04718|date=13 February 2018|doi=10.3390/aerospace5020057|bibcode=2018Aeros...5...57R|s2cid=119328461|doi-access=free}}

Musk had originally speculated that the car could drift in space for a billion years.{{cite tweet |user=elonmusk |author-link=Elon Musk |number=936782477502246912 |title=Payload will be my midnight cherry Tesla Roadster playing Space Oddity.

Radiation will eventually break down any material with carbon–carbon bonds, including carbon fiber parts. Tires, paint, plastic and leather might have lasted only about a year, while carbon fiber parts will last considerably longer. Eventually, only the aluminum frame, inert metals, and glass not shattered by meteoroids will remain.{{cite web |last1=Lezter |first1=Rafi |title=Radiation Will Tear Elon Musk's Rocket Car to Bits in a Year |url=https://www.livescience.com/61680-will-spacex-roadster-survive-in-space.html |website=LiveScience |date=February 6, 2018 |access-date=February 7, 2018 |archive-date=December 6, 2020 |archive-url=https://web.archive.org/web/20201206084933/https://www.livescience.com/61680-will-spacex-roadster-survive-in-space.html |url-status=live }}
