With several of her fellow crew members watching, STS-84 Mission Specialist Elena V. Kondakova, seated at center, gets instructions on using the slidewire baskets, part of the emergency egress system at Launch Pad 39A. Familiarization with pad procedures and systems is part of the Terminal Countdown Demonstration Test (TCDT) activities for the crew. Kondakova, a cosmonaut with the Russian space agency, is one of the seven STS-84 crew members for the sixth docking of the Space Shuttle with the Russian Space Station Mir. Another member, C. Michael 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. Kondakova previously lived on the Russian space station as the flight engineer of the 17th main mission on Mir from Oct. 4, 1994, to March 9, 1995. STS-84 is targeted for a May 15 liftoff
