This Cave Video Makes You Feel Like You’re On An Alien Planet

A few weeks ago, a bunch of astronauts went underground in Italy in the name of science and better finessing the techniques of running a space mission. A movie-style “preview” of their work plays in the video above.

You can see how jazzed the astronauts are about the mission. “It was like being on Mars,” one says. Another says this is inspiration to explore the solar system, because then you get to possibly see beautiful things such as what is right in front of them.

Better yet, there’s way more material where that movie came from. Check out the full playlist on YouTube.
