[i]One of the stated objectives of the Shuttle Mir Program, also known as Phase 1 of ISS, was for the United States and Russia to learn to work together as the two former adversaries prepared to jointly build and operate the space station. One arena where this was clearly demonstrated was in spacewalking. As Phase 1 progressed, astronauts living and working aboard Mir became more involved in the station's operations, including conducting EVAs. On April 29, 1997, Jerry M. Linenger became the first American astronaut to perform an EVA in a Russian Orlan spacesuit with his Mir 23 commander Vasili V. Tsibliev. C. Michael Foale and David A. Wolfe added to that experience base with their Mir Orlan EVAs later that year. Foale became the first person to perform EVAs in both the US EMU and the Russian Orlan spacesuits. On Oct. 1, 1997, Scott E. Parazynski and Vladimir G. Titov performed the first joint US-Russian EMU EVA during STS-86 while Space Shuttle Atlantis was docked to Mir. Titov was also the first non-American to conduct a Shuttle based EVA ... Astronaut Edward T. "Ed" Lu and cosmonaut Yuri I. Malenchenko conducted the first US Russian EVA at ISS during the June 2000 STS 101 mission. The two connected electrical and data cables between Zarya and the newly arrived Zvezda module. Training for that spacewalk required Russian engineers to modify the Hydrolab facility at the Gagarin Cosmonaut Training Center to accommodate the US EMUs. Similarly, American engineers adapted the Neutral Buoyancy Laboratory at Johnson Space Center to allow the Expedition 1 crew to train using both the EMU and the Russian Orlan spacesuit ... Following the Space Shuttle Columbia accident, ISS EVAs continued but only from the Russian segment with the added complication that with the resident crew size reduced to two, the pair of spacewalking crewmembers left no one inside the station to monitor its systems. Although this posed a slightly increased risk should something go wrong, these "two-person" EVAs proved essential during the Shuttle hiatus. Expedition 8 crewmembers Aleksandr Y. Kaleri and Mike Foale conducted the first such EVA on Feb. 26, 2004. Foale had prior experience with the Orlan suit as he had completed an EVA during his long-duration stay aboard Mir in 1997. The crew had to cut the EVA short due to Kaleri's suit overheating and water droplets forming inside his helmet. The crew later identified the problem as a kink in the water line in his liquid cooling garment. The incident provided a preview of a more serious problem to occur in an EMU during an EVA more than nine years later.[/i]
