Discovery's astronauts and cosmonauts, Commander Scott Horowitz, Pilot Rick Sturckow and Mission Specialists Pat Forrester and Dan Barry, and Expedition Three Commander Frank Culbertson, Pilot Vladimir Dezhurov and Flight Engineer Mikhail Tyurin, were awakened to "Back in the Saddle Again" by Gene Autry. It was played for Culbertson, making his third flight into space, eight years after he last flew.
At the time the crew was awakened, some 8000 statute miles separated Discovery from the ISS. A second firing of Discovery's orbital maneuvering systems engines is scheduled for early in the crew's day today to further adjust its orbit in preparation for rendezvous and docking with the station. Also scheduled today are the checkout of spacesuits to be worn by Barry and Forrester during two spacewalks next week, the preparation of rendezvous and navigation tools and a test of the shuttle's robotic arm, all routine work on the day before docking. Crewmembers also will perform a camera survey of Discovery's cargo bay with arm-mounted cameras.
Discovery is scheduled to linkup to the ISS tomorrow at 1:37 p.m. Central time as the two spacecraft fly over the Indian Ocean northwest of Australia, just south of the Indonesian island of Jawa.
The major objective of the STS-105 mission of Discovery is the swapout of the new resident Station crew, led by Culbertson, with the Expedition Two crew, Commander Yury Usachev and Flight Engineers Jim Voss and Susan Helms, who have been aboard the Station more than five months. They are to return to Earth aboard Discovery on August 22.
Discovery also is bringing equipment, supplies and scientific experiments to the Station. Almost 7,000 pounds of that cargo is in Leonardo, the Italian-built Multipurpose Logistics Module in Discovery's cargo bay. Once that is transferred to the station, Leonardo will be packed with other equipment, unused items and trash for return to Earth.
During their eight days docked to the station, Discovery Mission Specialists Barry and Forrester will perform two spacewalks. On the first, next Thursday, they will install a device called an Early Ammonia Servicer on the Station. It contains spare ammonia that could be used to cool Station systems should it be needed. During the second spacewalk, two days later, they will install heater cables for the station's large S0 truss segment, which will be delivered on a future mission, as well as handrails.
Discovery is orbiting the Earth in excellent shape with no issues being worked by the flight control team.
