December 3, 2001. Korolev, Moscow area.
The crew of the main expedition ISS-3 on the International
Space Station (ISS) have performed an EVA.
The objective of the EVA was to recover from an Off-Nominal
Situation (ONS) which occurred during docking of Progress
M1-7 logistics vehicle at the final phase of mating the
active Docking Assembly (DA) with the passive docking assembly
on Service Module Zvezda.
This situation prevented successful completion of nominal
docking timeline on November 29, 2001.
A preliminary ONS analysis, which included viewing video
records of Progress M-45 undocking from ISS, and Progress
M1-7 docking, showed that there was a flexible curved foreign
object on the docking plane of the Zvezda module docking
During the EVA performed from the Russian docking comparment,
Pirs module, cosmonauts M.Turin (flight engineer, cosmonaut
tester of RSC Energia) and V.Dezhurov (pilot, commander
of Soyuz TM) removed this object which turned out to be
a sealing rubber ring from the active docking assembly of
Progress M-45, which had remained on the Zvezda module DA
ever since they undocked on November 22, 2001. ISS-3 crew
commander Frank Culbertson stayed inside the space station
and monitored the extravehicular activities from within.
During EVA operations, on commands from the ground the logistics
vehicle was moved along the docking probe of its DA relative
SM, and eventually the probe was retracted to finally mate
the logistics vehicle with the space station.
As a result of the EVA operation, the vehicle docking with
ISS was finally completed.
In the course of the activities, and during the transit
of the cosmonauts between Pirs module and the docking area,
they took photographs, including those that support the
work under the program of space research and experiments
conducted on ISS.
The difficult and labor-intensive work of removing the sealing
ring was successfully completed owing to well coordinated
activities of cosmonauts and specialists from the Lead Operations
Control Team (LOCT).
The operation lasted 2 h 47 min. The EVA hatch on the Pirs
module was opened at 16:20 Moscow time, and it was closed
This was the fifth EVA performed by ISS crew.
It is planned to return the recovered sealing ring to Earth
for study in order to establish the causes of the situation,
which occurred for the first time in 30 years of operation
of this DA design.
Upon completion of the EVA, the seal of the interface was
checked, and on-board systems of the station were reset
to their initial condition.
Based on reports from the crew and LOCT that controlled
and monitored the space station mission from the Mission
Control Center near Moscow (MCC-M), the crew feels well
and the status of the ISS on-board systems is within design
During EVA operations of the ISS-3 crew, among those present
at the MCC-M were the Technical Director of Russia's manned
space program, General Designer of RSC Energia, member of
the Russian Academy of Sciences Yu.P.Semenov, Rosaviacosmos
Director General Yu.N.Koptev, RSC Energia specialists, representatives
of Rosaviakosmos and other organizations in the industry.
