The Space Shuttle Atlantis will land during one of the times below, and in one of the listed locations, between Thursday July 21 and Saturday July 23, 2011. The shuttles energy reserves will be 14 hours (it’s ability to keep flying) after these landing times.

Overnight, July 20-21, the shuttle undocked from the International Space Station (ISS), did a fly around the station before easing into an orbit that gradually, orbit by orbit, increased the distance between itself and the ISS. Atlantis is moving into a landing trajectory and then, about an hour before landing, will do a de-orbit burn to land at one of its three listed landing areas.

It is expected to land at Kennedy Space Center, Florida, the most preferred location of the three locations.

Tuesday afternoon, July 20, 2011, the weather looked favorable for the shuttle to successfully land in Florida on its first of two Florida opportunities. The shuttle would be landing at dawn on Thursday morning, July 22, 2011
