It's a series chronicling the history of US space travel, starts from the very first rocket into space up until the more present day stuff. Best thing I like about it is NASA footage that is digitally remastered and looks amazing. It's in HD on Netflix.
"The miniseries features interviews from Mercury, Gemini, Apollo, and Space Shuttle astronauts including John Glenn and Neil Armstrong, as well as NASA officials including flight directors Chris Kraft, Gene Kranz, and Glynn Lunney, former president George H. W. Bush and long-time NBC space journalist Jay Barbree.
The series is narrated by actor Gary Sinise"
