A multinational crew including a former Expedition crew member, an Italian astronaut and a South African businessman launched to the International Space Station, or ISS, on April 25, 2002, at 1:27 a.m. CST (0627 GMT). Once there, the Soyuz 4 Taxi crew conducted joint operations with the Expedition Four crew, performed educational and science activities and traded Soyuz space vehicles.

The Taxi crew rocketed from the Baikonur Cosmodrome, Kazakhstan, to deliver a fresh Soyuz spacecraft to the station for use as a lifeboat. The brand new Soyuz TM-34 spacecraft docked to the space station on April 27, 2002, at 2:56 a.m. CST (0756 GMT). About 1.5 hours later, the hatches swung open between the Soyuz and the ISS. The Soyuz 4 crewmembers exchanged seat liners from the new Soyuz to the 6-month-old Soyuz TM-33 in which they would ride home. After the Expedition Four crewmembers briefed the visiting crew on safety issues, they began nearly eight days of docked operations.

Soyuz Commander Yuri Gidzenko, on his third mission to space, is the first member of an Expedition crew to revisit the station. Gidzenko was a flight engineer during Expedition One, the first resident crew to live and work aboard the orbital outpost. On his first flight, Roberto Vittori -- an Italian astronaut representing the Italian Space Agency and working for the European Space Agency -- served as a flight engineer for the Soyuz crew. Under contract with Rosaviakosmos and representing South Africa as a space flight participant was businessman Mark Shuttleworth, also on his first flight.

Shuttleworth was the second private individual to pay for a mission to space. While onboard the outpost, Shuttleworth spoke to South African President Thabo Mbeki, Nobel Peace laureate Nelson Mandela and students from Bishops College in Cape Town, South Africa. The entrepreneur also brought onboard several science experiments that kept him busy each day during the mission.

Wrapping up its mission to the orbital outpost, the Soyuz 4 crew entered the Soyuz TM-33 docked since October of 2001. At 7:31 p.m. CST May 4, 2002 (1231 GMT May 5), the taxi crew undocked from the Pirs Docking Compartment with Gidzenko firing the engines separating the vehicle from the ISS. Later that day, Gidzenko conducted a four-minute de-orbit burn, beginning a descent toward Earth with the crew landing in Kazakhstan at about 10:52 p.m. CST May 4, 2002 (0352 GMT May 5).
