The trek back to VABstarted on Monday at 11:21 p.m. After the slow, four-mile journey, the space-bound vessel wassecured inside the buildingat 9:15 a.m.

The rollback comes after two aborted launch attempts.

In late August, during the first attempt, NASA discovered a problem with engine 3.

The second attempt saw a hydrogen leak force an abort.
