STS-86 Mission Specialist David A. Wolf waves to family members, friends and other well-wishers during a brief visit to Launch Pad 39A the day before the scheduled Sept. 25 launch aboard the Space Shuttle Atlantis. STS-86 is slated to be the seventh docking of the Space Shuttle with the Russian Space Station Mir. Wolf will be making his second spaceflight. After the docking, Wolf is scheduled to become a member of the Mir 24 crew, replacing U.S. astronaut C. Michael Foale. Wolf would remain on the Mir for about four months. Foale, who has been on the Mir since the STS-84 mission in mid-May, will return to Earth with the remaining six members of the STS-86 crew at the end of the planned 10-day flight
