Keep an eye on the live video from on board and let us know if you spot any aliens.

That Tesla roadster out in space will, like an asteroid, make its first close pass of Earth in 2091. I don’t think I’ll be around for that event, so I’ll post now.

After that pass by Earth, scientists say it has a 50 percent chance of continuing to orbit for a few tens of millions of years. Eventually, it will collide with a planet or fall into the Sun. If it makes it back to Earth, the atmosphere will burn up most of it before it hits the ground.

For now, it is safely on its way out past Mars, playing David Bowie to deaf, airless ears. It also carries on its dashboard screen the always appropriate message to Earthlings and anyone else who might encounter it: Don’t panic.
