New Launch Period for Zvezda Service Module
Technical representatives from NASA and the Russian Aviation and Space Agency have completed a Joint Program Review of issues related to the International Space Station Program. The partners agreed to move the projected launch window for the Zvezda Service Module to a period ranging from December 26 to January 16. An official launch date will be announced after the General Design Review in a few weeks.
The delay doesn't affect the overall launch and assembly schedule for the station since the launch dates for downstream flights likely will be adjusted because of ongoing wiring inspections on all space shuttles and recent work delays caused by Hurricane Floyd.
The Service Module will be the first fully Russian contribution to the International Space Station and will serve as the early cornerstone for the first human habitation of the station. The module will provide the early station living quarters; life support system; electrical power distribution; data processing system; flight control system; and propulsion system.

Preparations for Future Station Assembly Continue
Preparations for future station assembly continue at the Kennedy Space Center with the arrival Wednesday, August 4, of a second Italian-built logistics module, named Raffaello, targeted for launch to the station in mid-2000. Carried in the space shuttle's cargo bay, the 4.5-ton reusable module will hold up to 20,000 pounds of equipment racks for transfer to and from the station.

Commander Leroy Chiao (U.S.A.) and Flight Engineer Salizhan Sharipov (Russia), suited in Russian Orlan spacesuits, left the International Space Station on a 4.5 hour long spacewalk to install antennas for the European Automated Transfer Vehicle (ATV), inspect and photograph other exterior equipment and launched the Nanosatellite mini-satellite.  This is the last scheduled walk for the Expedition 10 crew.

At 06:25 UTC, the two astronauts left the station from the Pirs DC1 docking compartment/airlock and proceeded to install the last three of six space-to-space communication antennas for the ATV's rendezvous and docking with the ISS next year.

Sharipov next deployed the foot long, 11 pound Russian Nanosatellite, tossing it into space by hand. The object of the experiment is to develop small satellite control techniques, monitor satellite 
operations and develop new attitude system sensors. Russian ground crews reported good signal reception from the satellite two hours after its release. 

The two astronauts next proceeded to the aft end of the Zvezda service module. A Global Positioning System (GPS) antenna and necessary cabling for the ATV was installed and the men worked their way back to the airlock.

The station maintained its attitude, despite the loss of a gyroscope earlier in the space station mission, until the end of the spacewalk.  Chiao and Sharipov reported being a safe distance from the attitude adjustment thrusters.  Russian ground control activated the jets and normal attitude of
the station was regained.

They returned to the airlock at 1055 UTC, completing the mission an hour earlier than scheduled.

Chiao and Sharipov arrived on the station October 16, 2004.  They are scheduled to return to Earth on April 25, 2005. This marks Sharipov's second walk in space and Chiao's sixth.
