2. A Car

Imagine being an engineer for space launch and having your boss ask that you include an entire car in your payload calculations. Thanks, Elon. That was precisely the situation faced by SpaceX engineers in 2018 when the Falcon Heavy launch project used an entire Tesla Roadster as its dummy payload for launch.

The car is now in heliocentric orbit, meaning it orbits the sun, and it also crosses periodically into Mars’ orbit. The vehicle, which initially belonged to Musk and was used to drive to work, is the only production car in space. Of course, with Musk’s sense of advertising and humor, the car didn’t go into space alone.
