Thailand was a beautiful country and as I traveled around I was amazed by how friendly and helpful the people were. I've included a photograph of our experiment chamber with the plasma rocket engine inside. The engine is running with hydrogen propellant. You can see the plasma through the portholes in the chamber. The vapor that you see at the top of the chamber is from the liquid nitrogen, which we use to keep our electromagnets cool.
Preliminary tests indicate a successful change-out.
On Saturday, engineers were to confirm that Shuttle Atlantis' entire hydraulic system is functioning normally with a frequency response test of the orbiter's aerosurfaces and main engines. Review of the test data will conclude early this week. Last Thursday, workers completed efforts to replace the hydraulic fluid discharge hose on auxiliary power unit No.1 and the electronics box in the orbiter aft compartment. Managers have decided to replace a gaseous nitrogen quick disconnect on APU No. 2 this week as well. With a hypergolic pressure test already scheduled as part of standard launch preparations this week, no significant impact to the schedule is expected.
