An entity that struck an Australian man's Tesla arsenic helium was traveling on a road whitethorn person been a meteorite.
Andrew Melville-Smith, a veterinarian from Whyalla successful South Australia, told the Australian Broadcasting Corporation (ABC) that the entity deed his windscreen with specified unit that the solid appeared to soften and partially melt, and cracks spidered retired from the constituent of impact.
The car, which was reportedly successful Autopilot mode astatine the time, continued driving blithely arsenic though thing had happened.

Melville-Smith reported the incidental and its determination to the South Australian Museum, which is presently investigating to find the provenance of the projectile.
If the entity turns retired to beryllium a meteorite, it whitethorn beryllium the archetypal recorded lawsuit of a meteorite hitting a moving vehicle.
"I thought we'd crashed, it was that loud, it was that violent, it was wholly unexpected," Melville-Smith told the ABC. "The car was driving on and unconcerned … it wasn't alert of the chaos that was going connected successful the cabin."
Material from abstraction perpetually rains down connected Earth astatine a complaint of astir 5,200 tons per year. However, astir of that wide is successful the signifier of microscopic particulate that you'd not adjacent admit arsenic cosmogenic unless idiosyncratic told you.
There's a bully accidental you person teeny tiny meteorites accumulating successful your extortion gutters adjacent arsenic you work these words.
Larger chunks are rarer; they thin to burn and disintegrate successful the ambiance arsenic they fall. It's vanishingly uncommon that anyone adjacent sees a meteorite land, fto unsocial gets deed by one.
The museum's archetypal people of enactment is to analyse the windscreen itself to spot if immoderate particles whitethorn person embedded successful the glass. If the results are accordant with a abstraction origin, the mineralogists volition past spell hunt for the meteorite itself.
"The truly antithetic happening is that the solid of his windscreen has really melted a small bit; determination was a batch of vigor successful immoderate deed the windscreen," mineralogist Kieran Meaney of the South Australian Museum told the ABC.
Scientists judge that meteorites themselves are really rather acold erstwhile they onshore connected the surface; the vigor of atmospheric introduction tin pain and vaporize distant the aboveground furniture of the entity without transferring overmuch vigor to the interior.
However, if an entity is moving accelerated enough, it tin make aggravated vigor connected interaction arsenic its kinetic vigor is converted into thermal energy.
Nevertheless, different explanations whitethorn beryllium much likely, including space junk, thing falling from a passing aircraft, oregon adjacent conscionable an mean Earth rock.
"It whitethorn beryllium the lawsuit erstwhile we analyse further, we find retired it's thing different, but astatine the infinitesimal [a meteorite is] the mentation we are moving with," Meaney said.
"If we bash find retired that it is simply a meteorite, we volition astir apt extremity up going retired to wherever this happened and trying to find the spot of rock."
