Starman

When Elon Musk launched his Roadster on the inaugural flight of the Falcon Heavy, it was (more often than not) a fun PR stunt wrapped around a genuinely impressive issue. The mission wasn't entirely unscientific — the "Starman" at the bicycle of the roadster was dressed in SpaceX's commercial space suit and monitors were fastened to detect radiation levels — but information technology was more often than not a fun alternative to launching, say, a giant block of concrete. At present scientists think they can rule out Mars as a long-term probable final resting place for Musk's car.

That's peculiarly important, given what we know about Mars. The Roadster wasn't sterilized prior to its launch. And nosotros know that extremophile bacteria on Globe can survive in weather similar to that on Mars, including anaerobic bacteria that produce methane, a gas we've detected in Mars' atmosphere and take however to completely explicate. This does not hateful the methane is automatically produced by organic life (there are inorganic processes that tin can achieve the same issue), just that doubt is why some scientists were concerned. The last matter nosotros would desire to do is introduce Earth organisms into the Martian environment where they might kill the very organic life forms we'd like to find, before we've always establish them.

3 researchers at the University of Toronto have modeled the probable orbits of the Roadster. First, here's the vehicle's current position and orbit, courtesy of WhereIsRoadster. The site cheekily notes the Roadster has already blown through its 36,000 mile warranty 485.5 times (equally of this writing).

See how closely the Roadster's orbit is expected to rails our own? That'due south expected — it'south the result of the Roadster having launched from Earth. Simply it'southward also the reason why Mars isn't seen as a likely destination for the vehicle. As the Roadster orbits over time, the Earth volition go on to tug on its position when the 2 pass nearly one another.

This interplay makes it harder to tell what the Roadster's orbit volition look like in the long term; it could exist flung out of the near solar system and out into the Kuiper Belt, for example. Only based on the virtually likely weather condition, the Toronto researchers found a 6 pct chance that the Roadster ends upward back on Globe, and a 2.5 percent chance that it impacts Venus. The atmosphere on Venus is and then dense at ground level, meteors below a certain size don't hit the ground difficult enough to make impact craters. And volcanoes of the sort constitute on Earth are unknown, due to the incredible pressure level that actually prevents a lava fountain. The chances of life existing on the surface, at its balmy 800C, are basically nix.

The researchers believe the Tesla Roadster's lifespan in our solar system tin be measured in tens of millions of years, not hundreds of millions, fifty-fifty in the longest fourth dimension frames. While it'south possible that the car could still wind up impacting another planet, no evidence to suggest this was found within the iii.5 million-year window they examined. Hopefully nosotros'll have checked Mars for signs of life long before then. The GIF higher up, taken earlier this month, shows the Roadster in infinite equally visible through a telescope. In the weeks alee, it'll take far more powerful telescopes to keep the car in view. Only nosotros got to run across it with relatively elementary equipment for several days after the launch.
