Two additional collapsible water containers holding more than 10 gallons each are expected to be added to the cargo transfer list before the Shuttle leaves, bringing to 17 the number that will be left behind, a substantial increase in the amount of available water.
ISS Program Manager Bill Gerstenmaier said in a Saturday news conference that the program was very happy to have the additional supplies and that the station's consumables status had improved considerably with Discovery's visit.
Mission Manager Wayne Hale said Saturday that the added mission day will be added to the crew's schedule after the third spacewalk day.
Hale also noted Saturday that Discovery's protective tiles and thermal blankets passed review and are cleared for entry. Analysis continues on the reinforced carbon-carbon areas and two protruding gap fillers.
Also Sunday, astronauts will make preparations for the second spacewalk of the mission scheduled for Monday. Discovery's cabin pressure will be reduced to 10.2 psi to prepare Mission Specialists Stephen Robinson and Soichi Noguchi of the Japan Aerospace Exploration Agency for their work outside the spacecraft.
Space Shuttle and Space Station crewmembers will participate in two separate in-flight interviews. Shuttle Commander Eileen Collins, Pilot Jim Kelly and Mission Specialist Charlie Camarda will talk to reporters with ABC News, Fox News and NBC's "Meet the Press" at 5:49 a.m. CDT. Collins, Robinson, Noguchi and NASA ISS Science Officer John Phillips will speak with CBS News, CNN and Discovery Channel reporters at 7:39 a.m.
Discovery's crew was awakened at 11:11 p.m. CDT by the song "I'm Goin' Up," by Claire Lynch for Mission Specialist Wendy Lawrence. The Space Station crew was awakened about the same time by a tone onboard.
The crews of Discovery and the Space Station are scheduled to go to sleep about 2:09 p.m. CDT.
