The first season of Stargate Universe consists of 20 episodes. Brad Wright and Robert C. Cooper wrote the three-parter series opener named "Air", which was originally planned to be a two-parter. The first two parts of "Air" premiered on Syfy on October 2, 2009, with regularly weekly airing beginning on October 9, 2009. "Fire" was originally going to be the title for episode four, but the story and script was too big to be able to fit into one episode, so the producers changed it to become a two-parter called "Darkness" and "Light", therefore pushing all future episodes forward one slot. "Justice" was the mid-season finale. The back half of the first season aired on Friday April 2, 2010 on Space and Syfy.
