Computational fluid dynamics
John Shannon reported that the orbiter systems were in excellent shape, and had no issues. With regards to the remaining area of tile damage on the underside of the orbiter, Shannon reported that initial thermal analysis had been completed. Computational fluid dynamics testing at Ames Research Center had been done, and the preliminary results were "cautiously optimistic". Testing at the arc jet facility would continue Tuesday night. Shannon stated they would go through complete EVA scenario testing at the Neutral Buoyancy Lab, to help develop the EVA procedures if needed.
