It's not orbiting Earth, it's orbiting the sun. I think it's fair to say that it would be the most ambitious space mission we've ever taken to try and retrieve it, at least when not adjusting for our increased technical sophistication since the appolo era...

That would be a pretty expensive recovery. It's orbiting the Sun at about the same distance as Mars.

"The current location is 185,936,494 miles (299,235,874 km, 2.000 AU, 16.64 light minutes) from Earth, moving away from Earth at a speed of 2,944 mi/h (4,738 km/h, 1.32 km/s)."

I was going to mention that the one that has broken earth's orbit is the wrong vehicle and is not a first generation Tesla Roadster, but then I realised the repair woes are likely to be even worse for second generation Roadster owners. They're not likely to be produced in significantly more volume, and they're made totally in house, not based on a Lotus platform like the last one.

It seems that Musk realized that the only sane fate for the cars is to throw them away as far as you can.
