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.

Second Genesis follows planetary scientist Carolyn Porco as she explores what it takes to look for life beyond Earth, and what conditions are required for life to exist. Porco makes the case that Saturn’s moon Enceladus—with its plumes of water vapor spewing into space, confirmed organic materials, and evidence of hydrothermal vents at the bottom of its liquid ocean—is the most promising place to look. Could Enceladus be the key to proving once and for all that life is not unique to Earth? And what it would mean—both scientifically, and spiritually—if we found evidence of a true second genesis right here in our own galactic back yard?
