When Neil Armstrong stepped onto the moon in 1969, America went down in popular history as the winner of the space race. But that history is bunk. The real pioneers of space exploration were the Soviet cosmonauts. This documentary combines rare and unseen archive footage with interviews with the surviving cosmonauts to tell the fascinating and at times terrifying story of how the Russians led us into the space age. A particular highlight is Alexei Leonov, the man who performed the first spacewalk, explaining how he found himself trapped outside his spacecraft 500 miles above the Earth.

The film, which follows a group of teens at NASA's space camp as they learn about the science and technology behind a trip to Mars, also features commentary by science popularizers Bill Nye, Neil deGrasse Tyson, Michio Kaku; astronaut Suni Williams, and Andrew Weir, author of The Martian. But it's not the grownups who make the film; none of them, with the exception of Williams, has any shot at all of walking on Mars. It's the kids, who can dream that dream, who are the deserved focus of the narrative.

Although in reality specific things need to happen to create different kinds of black holes, from really tiny ones to the largest single things in the universe. So how do black holes grow and how large is the largest of them all?
