Space shuttle Endeavour on Sunday cut short its visit to the International Space Station, even though it now appears that Mission Control will not be threatened by Hurricane Dean.

Landing is targeted for 12:31 p.m. ET Tuesday, rather than Wednesday as originally scheduled. Because of the early end to the mission, the astronauts had to leave a few tasks undone, and Endeavour teacher-astronaut Barbara Morgan had to skip a conversation with schoolchildren.

The shuttle usually circles the station after undocking so the crew can take photos to check the station's condition, but that step was dropped Sunday to save time.

The early cutoff of Endeavour's flight also forced NASA to abridge Saturday's spacewalk by an hour, leaving undone the task of fastening down some shields that protect the station from space debris. The station crew or the astronauts on the next shuttle flight can probably finish the job, deputy shuttle program manager John Shannon has said.

The Endeavour crew spent most of Sunday inspecting the spacecraft's exterior in preparation for re-entry, focusing on potential damage from space junk on the shuttle's wings and nose.
