The sevenmember crew is participating in Terminal Countdown Demonstration Test (TCDT) activities. From left, are Pilot Eileen Marie Collins, and Mission Specialists Carlos I. Noriega, Edward Tsang Lu, Jean-Francois Clervoy of the European Space Agency, C. Michael Foale and Elena V. Kondakova of the Russian Space Agency. NASA astronaut Mario Runco Jr., next to Kondakova in a blue flight suit, is assisting the crew during TCDT. STS-84 will be the sixth docking of the Space Shuttle with the Russian Space Station Mir. After docking, Foale will transfer to the space station and become a member of the Mir 23 crew, replacing U.S. astronaut Jerry M. Linenger, who will return to Earth aboard Atlantis. Foale will live and work on Mir until mid-September when his replacement is expected to arrive on the STS-86 mission. STS-84 is targeted for a May 15 liftoff
