Late in the mission, the crew reported what appeared to be venting from the aft compartment. This thruster also was not fired during the entire mission. All thrusters except L3A and R4U were fired during the RCS hot-fire test. A decision was made to not fire the L3A and R4U thrusters because of the leaks noted earlier in the mission. The crew completed Spacelab operations, as well as entry preparations and stowage.
Preliminary indications are that the rollout was normal in all respects.
The flight duration was 8 days 1 hour 15 minutes 43 seconds.
