Launch from the Baikonur Cosmodrome; landing 95 km northeast of Arkalyk.

This mission carried out the ISS Expedition 9. They were called a "caretaker" crew. Following a two day solo flight Soyuz TMA-4 docked to ISS on April 21, 2004. Gennadi Padalka and Michael Fincke replaced the Expedition 8 crew. The crew performed 21 new experiments and four spacewalks.

Together with the new ISS crew European Space Agency (ESA) Astronaut André Kuipers reached the station. After more than a week of joint operations and handover activities, Gennadi Padalka and Michael Fincke officially took command of the Station on April 29, 2004 when Expedition 8 Commander Michael Foale and Flight Engineer Aleksandr Kaleri left the Station. This mission was the site for the Advanced Diagnostic Ultrasound in Microgravity Project. Expedition 8 and André Kuipers returned to Earth that same day aboard the Soyuz TMA-3 spacecraft. André Kuipers' 11-day mission to the ISS was part of a commercial agreement between ESA and the Federal Space Agency of Russia.

The EVA 1 by Gennadi Padalka and Michael Fincke was aborted on June 24, 2004 after 14 min (planned 6 hours) because of a high rate pressure lost in the primary oxygen bottle of Michael Fincke's Orlan spacesuit.

The second EVA by Gennadi Padalka and Michael Fincke occurred on June 30, 2004 (5h 40 min) to install a new circuit breaker to restore power to one of four gyroscopes that help orient the complex, two flexible handrails, to mount a contamination monitor to measure Station thruster exhaust, and to add end caps to two circular handrails on the airlock.

Progress M-49 was launched at 12:34:23 UTC on May 25, 2004. The spacecraft docked with the Aft port of the Zvezda module at 13:54:43 UTC on May 27, 2004. Progress M-49 carried supplies to the International Space Station, including food, water and oxygen for the crew and equipment for conducting scientific research. The freighter remained docked for two months before undocking at 06:04:48 UTC on July 30, 2004 to make way for Progress M-50. It was deorbited at 10:37:00 UTC on the same day. The spacecraft burned up in the atmosphere over the Pacific Ocean, with any remaining debris landing in the ocean at around 11:23:35 UTC.

The third EVA was performed by Gennadi Padalka and Michael Fincke on August 03, 2004 (4h 30 min) replacing several materials exposure experiment packages and a thruster contamination monitor, installing reflectors and communications equipment needed for the docking of a new European Space Agency cargo ship, which shall dock on the ISS in 2005.

Progress M-50 was launched at 05:03:07 UTC on August 11, 2004. The spacecraft docked with the Aft port of the Zvezda module at 05:01:08 UTC on August 14, 2004. Progress M-50 carried supplies to the International Space Station, including food, water and oxygen for the crew and equipment for conducting scientific research. The freighter remained docked for four months before undocking at 19:37:02 UTC on December 22, 2004 to make way for Progress M-51. It was deorbited at 22:32:06 UTC on December 22, 2004. The spacecraft burned up in the atmosphere over the Pacific Ocean, with any remaining debris landing in the ocean at around 23:23:38 UTC.

The fourth and final EVA by Gennadi Padalka and Michael Fincke was conducted on September 03, 2004 (5h 21m) installing three antennas on the exterior of the Zvezda Service Module that will aid the automated docking of a new Station supply craft, the European Automated Transfer Vehicle, replacing of a pump panel on the Zarya module, installation of guides for spacesuit tethers on Zarya handrails; installation of handrail covers near the Pirs Docking Compartment hatch.
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.

The Soyuz spacecraft is composed of three elements attached end-to-end - the Orbital Module, the Descent Module and the Instrumentation/Propulsion Module. The crew occupied the central element, the Descent Module. The other two modules are jettisoned prior to re-entry. They burn up in the atmosphere, so only the Descent Module returned to Earth.
Having shed two-thirds of its mass, the Soyuz reached Entry Interface - a point 400,000 feet (121.9 kilometers) above the Earth, where friction due to the thickening atmosphere began to heat its outer surfaces. With only 23 minutes left before it lands on the grassy plains of central Asia, attention in the module turned to slowing its rate of descent.
Eight minutes later, the spacecraft was streaking through the sky at a rate of 755 feet (230 meters) per second. Before it touched down, its speed slowed to only 5 feet (1.5 meter) per second, and it lands at an even lower speed than that. Several onboard features ensure that the vehicle and crew land safely and in relative comfort.
Four parachutes, deployed 15 minutes before landing, dramatically slowed the vehicle's rate of descent. Two pilot parachutes were the first to be released, and a drogue chute attached to the second one followed immediately after. The drogue, measuring 24 square meters (258 square feet) in area, slowed the rate of descent from 755 feet (230 meters) per second to 262 feet (80 meters) per second.
The main parachute was the last to emerge. It is the largest chute, with a surface area of 10,764 square feet (1,000 square meters). Its harnesses shifted the vehicle's attitude to a 30-degree angle relative to the ground, dissipating heat, and then shifted it again to a straight vertical descent prior to landing.
The main chute slowed the Soyuz to a descent rate of only 24 feet (7.3 meters) per second, which is still too fast for a comfortable landing. One second before touchdown, two sets of three small engines on the bottom of the vehicle fired, slowing the vehicle to soften the landing.
