KENNEDY SPACE CENTER, FLA. -- In high bay 3 of NASA's Vehicle Assembly Building, a crane lowers the orbiter Discovery into place alongside its external tank and twin solid rocket boosters for mating. Discovery will be mated with its external tank and twin solid rocket boosters waiting below on the mobile launcher platform. Space Shuttle Discovery is expected to roll out to Launch Pad 39B later this week via the crawler-transporter. Launch of Discovery on mission STS-121 is scheduled to take place in a window extending July 1 to July 19. Photo credit: NASA/Charisse Nahser
