NASA STS-122 Execute Package FD13
The MMT met to review mission progress, orbiter status, and entry weather forecast. Atlantis is performing extremely well and with no new systems items presented. The starboard radiator hose entry plan was presented. The hatches were closed prior to the beginning of the MMT.
Starboard Aft Radiator Retract Hose – The bend in this hose pre-flight is expected to reoccur when the payload bay doors are closed for entry. However due to the concern discussed pre-flight regarding isolating the radiator, it will not be isolated for door closing. It was also decided to not isolate the radiator for entry, as was also discussed pre-flight. It is not required to isolate the radiator for entry for several reasons. Evaluation of this hose on Atlantis shows it to be in much better shape than the hose from Discovery after that hose was cycled up to two dozen times. Neither hose has ever leaked. Also, the corner of the V- guide near the hose was sanded into a gentle rounded shape to minimize impacts of rubbing on the hose. Finally, if the hose does leak, nominal procedures are designed to manage this failure. For these reasons, it was decided not to isolate the radiator for entry. During Payload Bay Door closing, we will record 3 of the 4 hoses for post flight review and also request you to provide a verbal status after the doors are closed.
Entry Weather Forecast – The front that pushed through Houston last night will push through KSC on Tuesday leaving a high pressure system over KSC and a clear, cool morning for landing. See below.
