STS092-S-022 [EC00-0311-3](24 OCTOBER 2000) --- The drag chute on the Space Shuttle Discovery is deployed as the vehicle rolls toward mission completion at Edwards Air Force Base in the Mojave Desert of California. Onboard were astronauts Brian Duffy, Pamela A. Melroy, Leroy Chiao, William S. McArthur, Jr., Peter J.K. (Jeff) Wisoff, Michael E. Lopez-Alegria, and Koichi Wakata of Japan's National Space Development Agency (NASDA). Discovery touched down at 2 p.m. (PDT), October 24, and rolled to a stop on Edward's concrete runway at 2:0l, for a mission elapsed time of 12 days, 21 hours and 43 minutes.

STS008-14-378 (30 Aug-5 Sept 1983) --- Astronaut William E. Thornton, a very busy mission specialist conducting a great deal of bio-medical experimentation, checks a prolific roll of data in the mid deck of the Earth-orbiting Space Shuttle Challenger. The electrode on Dr. Thornton’s forehead indicates that his four crewmates were not his only test subjects during the extensive test on this six-day flight.

KENNEDY SPACE CENTER, FLA. -- In the Vehicle Assembly Building (VAB), United Space Alliance technician Robert Williams sands the repaired areas near the top of Space Shuttle Discovery's external tank. Repairs were required for damage caused by hail during recent storms. Because access to all of the damaged areas was not possible at the pad, the Shuttle was rolled back from Pad 39B to the VAB. The work is expected to take two to three days, allowing Discovery to roll back to the pad late this week for launch of mission STS-96, the 94th launch in the Space Shuttle Program. Liftoff will occur no earlier than May 27. STS-96 is a logistics and resupply mission for the International Space Station, carrying such payloads as a Russian crane, the Strela; a U.S.-built crane; the Spacehab Oceaneering Space System Box (SHOSS), a logistics items carrier; and STARSHINE, a student-shared experiment

S73-34369 (14 Aug. 1973) --- A Saturn 1B launch vehicle is rolled to Launch Complex 39, Pad B. The space vehicle, to be launched by the Saturn 1B, will carry the third Skylab crew (Skylab 4) to the now-orbiting Orbital Workshop (OWS) and the other four components making up the cluster. The Skylab crewmen, astronaut Gerald P. Carr, commander; scientist-astronaut Edward G. Gibson, science pilot; and astronaut William R. Pogue, pilot, are scheduled to be launched from here in November 1973. Photo credit: NASA

STS092-S-021 [EC00-0311-2](24 October 2000 --- The main landing gear on the Space Shuttle Discovery is just about to touch down to mark mission completion at Edwards Air Force Base in the Mojave Desert of California. Onboard were astronauts Brian Duffy, Pamela A. Melroy, William S. McArthur, Jr., Leroy Chiao, Michael E. Lopez-Alegria, Peter J.K. (Jeff) Wisoff and Koichi Wakata of Japan's National Space Development Agency (NASDA). Discovery touched down at 2 p.m. (PDT), October 24, and rolled to a stop on Edward's concrete runway at 2:0l, for a mission elapsed time of 12 days, 21 hours and 43 minutes.
