I saw this Netflix original doc the other day, and it's a winner! This movie goes back and forth between two things -- so it's almost like 2 movies rolled into one. One of them is a look inside the "Space Camp" that inspired that movie from the '80s, and the other more fascinating angle is a documentary featuring the history of the exploration of Mars, and the state of the space program -- you'll see interviews with the usuals -- Neil DeGrasse Tyson, Bill Nye "the Science Guy", etc... as well as countless other scientists, astronauts, scholars, etc.. Definitely worth checking out!
