NASA marked a special anniversary Saturday. Space Shuttle Atlantis launched for the first time on Oct. 3, 1985.

Atlantis is now on display at the Kennedy Space Center Visitor Complex.

Astronauts who flew on Atlantis are sharing their favorite memories of the orbiter.

“I was on the mid deck, for re-entry so I asked the commander if I stay up a little bit, so I stayed up, a little over 4 hours and for those that know the space program, four hours you go around the Earth three times and it’s just one of those things were I kind of felt like I owned the world, so that was one of my great memories flying on Atlantis,” said Astronaut Mark Lee.

Atlantis is also known as the last space shuttle to fly in space.
