24. If your great-great-grandchildren end up living on Mars, they will encounter some pretty weird things.
You can probably tell by now that living on Mars, if we are one day able to get that far, will be very, very different from living on Earth. Moreover, there will be many cool things that people who live on Mars will see, like what appears to be a face in the sand and strange wind patterns that have created what looks like Morse code.
The night sky will also be very different, given that instead of the one giant moon that we see here on Earth, people living on Mars would see two tiny moons that orbit the planet quite rapidly. Stars will appear to be in a different place altogether, and the sunrise and sunset will look nothing like they do on Earth.
