(04/28/1997) --- STS-84 crew members listen intently to Commander Charles J. Precourt, at far right, as he talks to news media representatives and other onlookers at Launch Pad 39A during the Terminal Countdown Demonstration Test (TCDT). Other crew members, from left, are Mission Specialist Edward Tsang Lu, Pilot Eileen Marie Collins, and Mission Specialists Carlos I. Noriega, Jean-Francois Clervoy of the European Space Agency, C. Michael Foale, and Elena V. Kondakova of the Russian Space Agency. 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
