Expedition 9 was the 9th expedition to the International Space Station
International Space Station
The International Space Station is a habitable, artificial satellite in low Earth orbit. The ISS follows the Salyut, Almaz, Cosmos, Skylab, and Mir space stations, as the 11th space station launched, not including the Genesis I and II prototypes...



Mission parameters

  • Perigee
    Perigee is the point at which an object makes its closest approach to the Earth.. Often the term is used in a broader sense to define the point in an orbit where the orbiting body is closest to the body it orbits. The opposite is the apogee, the farthest or highest point.The Greek prefix "peri"...

    384 km
  • Apogee: 396 km
  • Inclination
    Inclination in general is the angle between a reference plane and another plane or axis of direction.-Orbits:The inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit...

  • Period
    Orbital period
    The orbital period is the time taken for a given object to make one complete orbit about another object.When mentioned without further qualification in astronomy this refers to the sidereal period of an astronomical object, which is calculated with respect to the stars.There are several kinds of...

 spacecraft. Kuipers' 11-day mission to the ISS was part of a commercial agreement between ESA and the Federal Space Agency of Russia.


The Expedition 9 crew conducted four spacewalks during its stay at the International Space Station. The four spacewalks were devoted to ISS maintenance and assembly. All four were based out of the Pirs Docking Compartment and used Russian Orlan spacesuits.

Before these four extravehicular activities (EVAs), 52 spacewalks had been performed at the ISS, with 27 based out of the Station.

Gennady Padalka (EV1): red stripes
Mike Fincke (EV2): blue stripes

Spacewalk 1
Gennady Padalka, Mike Fincke
Time: 14 minutes, 22 seconds
Start time: 4:56 p.m. CDT (2156 GMT) 24 June 2004
End time: 5:10 p.m. CDT (2210 GMT) 24 June 2004

The spacewalk was cut short due to a pressure problem in Fincke's prime oxygen tank in his spacesuit. Mission managers decided to reschedule the spacewalk for 30 June.

Spacewalk 2
Gennady Padalka, Mike Fincke
Time: 5 hours, 40 minutes
Start time: 4:19 p.m. CDT (2119 GMT) 29 June 2004
End time: 9:59 p.m. CDT 29 June 2004 (0259 GMT 30 June 2004)

Padalka and Fincke replaced a Remote Power Controller (RPCM) that failed in late April, causing a loss of power in Control Moment Gyroscope No. 2 (CMG 2). A failed Remote Power Controller Module was responsible for the temporary loss of CMG 2 in April. The gyroscope is one of four that control the ISS' orientation.

Spacewalk 3
Gennady Padalka, Mike Fincke
Time: 4 hours, 30 minutes
Start time: 1:58 a.m. CDT (0658 GMT) 3 August 2004
End time: 6:28 a.m. CDT (1128 GMT) 3 August 2004

In preparation for the arrival of the European Space Agency's Automated Transfer Vehicle (ATV), Padalka and Fincke removed laser retro reflectors from the Zvezda Service Module assembly compartment and installed three updated laser retro reflectors and one internal videometer target. They installed two antennas.

The spacewalkers removed Kromka Panel No. 2 and installed Kromka Panel No. 3. The Kromka experiment exposes various materials to the space environment. They also replaced another materials science experiment.

Spacewalk 4
Gennady Padalka, Mike Fincke
Time: 5 hours, 20 minutes
Start time: 16:43 UTC, 3 September 2004
End time: 22:04 UTC, 3 September 2004

Expedition 9's fourth scheduled EVA prepared the Station for future assembly operations and the arrival of the ATV. The spacewalkers replaced the Zarya Control Module flow control panel and installed four safety tether fairleads on Zarya's handrails.

ATV support operations included installing equipment for the air-to-air radio link antennas and removing all covers from antennas.

Other tasks included installing a Pressure Control and Exposure Monitor Sensor on Pirs and installing protective components on the brackets of Pirs' ring handrails on EVA Hatch No. 2.
