Early Sunday morning, Space Shuttle Atlantis began its journey back to Kennedy Space Center “piggy-backed” on top of a modified 747 jetliner called the Shuttle Carrier Aircraft.

The enroute plan includes refueling stops and a stop overnight. The anticipated arrival at the Kennedy Space Center will be no earlier than Monday July 2 with a possibility of arriving Tuesday July 3 if weather conditions are not favorable for a Monday landing.

Atlantis landed at Edwards concluding a successful assembly mission to the International Space Station with Commander Rick Sturckow and Pilot Lee Archambault at the controls. Atlantis landed at 3:49 p.m. EDT on June 22.

The STS-117 mission astronauts returned to Johnson Space Center on Saturday, June 23. Their return was marked by a traditional welcome home ceremony at Ellington Field in Houston.
