Today is the anniversary of the best-worst day of your life. The best part was discovering a subterranean city on Mars. The worst part was when you lost contact with Earth. You and the other 99 scientists have spent the year engineering your survival, but you're almost out of water and solutions. Can you figure out how the last civilization lived on this desert planet? Henri Picciotto shows how. \[Directed by Igor Coric, Artrake Studio, narrated by Addison Anderson, music by Cem Misirlioglu\].
