Stock Photo - Space Shuttle Discovery was about 600 feet from the International Space Station when cosmonaut Sergei K. Krikalev, Expedition 11 commander, and astronaut John L. Phillips, NASA Space Station science officer and flight engineer, photographed the spacecraft as it approached the Station and performed a backflip to allow photography of its heat shield. Astronaut Eileen M. Collins, STS-114 commander, guided the Shuttle through the flip. The photos will be analyzed by engineers on the ground as additional data to evaluate the condition of Discovery?s heat shield. The Italian-built Raffaello Multi-Purpose Logistics Module (MPLM) is visible in the cargo bay.
