Science DiscussionsNASA and contractor engineers will check both valves, replace the bad one with a spare valve, and then test the integrity of the cabin’s pressure. The task is expected to be finished by Thursday, August 2, 2007, well ahead of the scheduled STS-118 launch on the seventh of August. The valves are used to assure that the crew cabin, where the astronauts live and work, maintains a proper atmospheric pressure. When an overload condition arises, the properly working valves release pressure from inside the astronaut quarters. A small problem was also found with Endeavour’s auxiliary power units (APUs). The thermostats are reporting off-norm (out of the normal range) values. However, the thermostats will not be replaced and a work-around will be implemented to accommodate the erroneous readings. Additional information on the upcoming mission of the Space Shuttle Endeavour and its STS-116 mission is found at the iTWire article: “STS-118 crew practice at Kennedy for August launch of Endeavour” (http://www.itwire.com/content/view/13572/1066/).
