OFFICIAL PRESS RELEASE
about activities in open space
of the ISS expedition nine crew under EVA program
 

July 1, 2004. Korolev, Moscow Region.

The crew of expedition nine to the International Space Station (ISS) - Russian cosmonaut Gennady Padalka (ISS-9 Commander) and US astronaut Michael Fincke (ISS-9 Flight Engineer) - have carried out their second space walk on the outer surface of the space station.
The objective of the space walk was to perform work under a program of extravehicular activities (EVA) which included replacement of a failed RPCP unit for remote power control of Control Motion Gyro CMG 2, installed on truss S0 of the US orbital segment.
This is the tenth space walk of ISS crews performed from the Russian segment. The previous space walk performed on June 25 was cut short because of pressure drop in the main oxygen bottle in Michael Fincke's spacesuit detected from telemetry data 10 minutes after opening the exit hatch on the Pirs docking module and caused by the failure to completely close the injector activation valve in his suit. This valve has a peculiar design feature: while it is being closed, one must make sure not only that the signal light went out, but also that the handle has been locked.
During preparations for a repeat of EVA started on June 26, the crew and the ground services assured the operational readiness of the same Orlan-M space suites that were used in the previous space walk, checked out and prepared equipment and tools, communications and medical parameter monitoring systems, once again conducted necessary training sessions and consultations with the specialists.
The exit hatch of the Russian Pirs module was opened at 1:19 Moscow Time.
Upon successful completion of activities under EVA program performed over a period of 5 hours 40 minutes, Gennady Padalka and Michael Fincke returned into the Pirs module, closing its exit hatch at 06:58.
The space walk resulted in restoring the functionality of the US Control Motion Gyro CMG 2, installing on Pirs module a device for measuring vacuum levels and detecting microparticles near the station surface, as well as additional safety elements to provide a more convenient crew translation path to working areas on the outer ssurface of the ISS during subsequent EVAs.
The crew and their equipment moved over the Russian segment between Pirs module and Functional and Cargo Module (FGB) Zarya using a cargo boom installed on the Pirs module, and between FGB and the work area using crew restraints available on the surfaces of the modules and US orbital segment trusses.
Operations under EVA program were performed within coverage areas of the Russian ground tracking stations. Outside these areas, data exchange between ISS and Mission Control Center near Moscow (MCC-M) wes supported by US facilities.
According to reports from the crew and Lead Operations Control Team (LOCT) who monitor and control the Russian segment mission from MCC-M, the crew is in good health and the space station on-board systems status is as-designed.
The ISS space station currently consists of: FGB Zarya, Service Module Zvezda, docking module Pirs, transportation spacecraft Soyuz TMA-4 and Progress M-49, Unity and Destiny modules, Quest airlock and a multi-segment truss structure with deployed solar arrays.
The station flies in low Earth orbit with the following parameters: maximum altitude of 375.2 km, minimal altitude of 358.3 km, orbital period 91.6 min.
The next space walk of the ISS-9 crew on the outer surface of ISS is planned for early August, 2004, as the head of LOCT, pilot-cosmonaut V.A.Soloviev said to the newsmen at the briefing held at MCC-M upon completion of the EVA.
