Nothing captivates us in the same way that space travel does, and today millions of Americans tuned in to watch the final shuttle mission for NASA: STS-135. Science will debut a new special, Last Shuttle: Our Journey, tonight at 10pm ET/PT — following the preparations for the final mission and telling the story of the Shuttle program through the eyes of the people who know it best.

Our colleague Kate was fortunate to be one of 150 attendees at the #NASATweetup yesterday and today, in conjunction with the final Atlantis mission. She’s been reporting on behalf of Science for space enthusiasts around the world from both @ScienceChannel and the Science Facebook page, and meeting everyone from Elmo (complete in NASA space suit) to Astronauts Mike Massimino & Doug Wheelock. I can’t wait to hear all about it when she returns, especially after seeing this video of the launch from the ground.

Check out a preview of tonight’s Last Shuttle special (maybe try to find some astronaut ice cream beforehand) and dig deeper with Wide Angle coverage from the team at Discovery News.
