This rather large SpaceX rocket is called the Falcon Heavy. Inside is the automobile below, which SpaceX hopes to launch in orbit around Mars with a flight schedule February 6, 2018 (assuming it doesn’t blow up on the launchpad).
You just can’t make this stuff up. The automobile, which belongs to the founder of SpaceX Elon Musk, is a Tesla Roadster. If successful, the automobile could stay in orbit around Mars for a few billion years. The car will just be let go to float on it’s own ’round and ’round Mars.
I guess that’s in case you ever need to catch a ride to orbit Mars!
