Marco Polo was Roberto Vittori's first spaceflight and a short-duration visiting mission to the International Space Station. The crew launched from Baikonur on Soyuz TM-34 on April 25, 2002, docked with the ISS two days later, and returned to Earth on Soyuz TM-33 on May 5 after exchanging the station's Soyuz lifeboat. The mission carried Russian commander Yuri Gidzenko, ESA/ASI astronaut Roberto Vittori, and South African private spaceflight participant Mark Shuttleworth.
