Discovery nearing the station

The shuttle Discovery is closing in on the international space station for a linkup today around 5:05 p.m. The terminal phase of the rendezvous procedure will begin with a rocket firing at 2:28 p.m. Trailing the station by about eight nautical miles, commander Mark Polansky will guide Discovery through a carefully choreographed approach that will put the shuttle about 600 feet directly below the lab complex a few minutes past 4 p.m.

The space station crew will train telephoto lenses on the shuttle as Polansky guides the craft through a 360-degree pitch maneuver, exposing Discovery's belly to view for a detailed heat shield inspection. The shuttle's nose cap and wing leading edge panels were inspected by the Discovery astronauts Sunday and today's inspection is intended to characterize the health of the tiles that play such a crucial role during re-entry.

With the rotational pitch maneuver complete, Polansky will guide Discovery to a point about 310 feet directly in front of the station with the orbiter's tail pointing toward Earth and its open cargo bay toward pressurized mating adapter No. 2 on the forward end of the Destiny laboratory module.

From that point, it will take about 40 minutes to complete the rendezvous, with docking on tap around 5:05 p.m. If all goes well, hatches between the two spacecraft will be opened about an hour later and after a brief welcoming ceremony and safety briefing, the combined crews will press ahead with a busy schedule.

For station commander Michael Lopez-Alegria, flight engineer Mikhail Tyurin and European Space Agency astronaut Thomas Reiter, the highlight of the day will be transferring astronaut Sunita Williams' Soyuz seat liner from Discovery to the station. At that point, around 8 p.m., Williams will become a member of the Expedition 14 crew. Reiter, launched to the station in July, will return to Earth aboard Discovery in Williams' place.

A few minutes after the seat liner transfer, Nicholas Patrick, operating the shuttle's 50-foot-long robot arm, will latch onto the P5 solar array truss segment making up Discovery's major cargo. After hoisting the segment out of the payload bay, Patrick will position it for handoff to the station's robot arm, operated by Williams, around 9 p.m. P5 will remain parked overnight on the end of the station arm until installation Tuesday during a spacewalk by Robert Curbeam and Swedish astronaut Christer Fuglesang.
