Expedition 9 (2004) was the ninth expedition to the International Space Station (21 April 2004 - 23 October 2004).
Padalka and Fincke arrived at the Station on 21 April 2004 aboard the Soyuz TMA-4 spacecraft with European Space Agency (ESA) Astronaut André Kuipers. After more than a week of joint operations and handover activities, Padalka and Fincke officially took command of the Station on 29 April when Expedition 8 Commander Michael Foale and Flight Engineer Alexander Kaleri left the Station. This mission was the site for the Advanced Diagnostic Ultrasound in Microgravity Project.
Expedition 8 and Kuipers returned to Earth that same day aboard the Soyuz TMA-3 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.

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.
