STS046-03-032 (31 July-8 Aug 1992) --- Astronaut Marsha S. Ivins, mission specialist, prepares to operate a tandem of 70mm Hasselblad cameras on the Space Shuttle Atlantis' aft flight deck. The cameras share a common mount, allowing for various tests to be run as the cameras record the same Earth-observations type imagery. Ivins was joined by four other NASA astronauts and two Europeans for an eight-day stay in Earth-orbit.
