S71-43202 (5 Aug. 1971) --- Astronaut Alfred M. Worden, command module pilot of the Apollo 15 lunar landing mission, floats in space outside the spacecraft during his trans-Earth extravehicular activity (EVA). This photograph was taken from a frame of motion picture film exposed by the 16mm Maurer camera mounted in the hatch of the Command Module (CM). During his EVA, Worden made an inspection of the Service Module's (SM) Scientific Instrument Module (SIM) bay and retrieved the film cassettes from the Panoramic Camera and the Mapping Camera. The SIM bay holds eight orbital science experiments. The EVA occurred when the spacecraft was homeward bound approximately 171,000 nautical miles from Earth.

STS087-371-013 (19 November - 5 December 1997) --- On the Space Shuttle Columbia's mid-deck, astronaut Steven W. Lindsey proves that the Autonomous Extravehicular Activity Robotic Camera/Sprint (AERCam/Sprint) experiment is in fact bigger than a soccer ball, to which it is often erroneously compared for dimensional frame of reference, as he allows the Sprint to float near him. The AERCam is a prototype free-flying television camera that could be used for remote inspections of the exterior of the International Space Station (ISS). Later, astronauts Winston E. Scott and Takao Doi took the experiment outside for a brief test during the mission's second Extravehicular Activity (EVA). Lindsey, pilot, is standing with his back to the galley and his left hand on the microgravity glovebox, used extensively during the mission to support the United States Microgravity Payload (USMP-4) mission.

STS-87 Mission Specialist Winston Scott poses in his orange launch and entry spacesuit with NASA suit technicians at Launch Pad 39B during Terminal Countdown Demonstration Test (TCDT) activities. The crew of the STS-87 mission is scheduled for launch Nov. 19 aboard the Space Shuttle Columbia. Scott will be performing an extravehicular activity (EVA) spacewalk during the mission. The TCDT is held at KSC prior to each Space Shuttle flight providing the crew of each mission opportunities to participate in simulated countdown activities. The TCDT ends with a mock launch countdown culminating in a simulated main engine cut-off. The crew also spends time undergoing emergency egress training exercises at the pad and has an opportunity to view and inspect the payloads in the orbiter's payload bay

Known in technical circles as Node 2, it is similar to the six-sided Unity module that links the U.S. and Russian sections of the station. Built in Italy for the United States, Harmony will be the first new U.S. pressurized component to be added. The STS-120 mission is targeted to launch on Oct. 20. Photo credit: NASA/George Shelton

Astronaut Michael E. Fossum, STS-121 mission specialist, used a digital still camera to expose a photo of his helmet visor during a session of extravehicular activity (EVA) while Space Shuttle Discovery was docked with the International Space Station (ISS). Also visible in the visor reflections are fellow space walker Piers J. Sellers, mission specialist, Earth's horizon, and a station solar array. During its 12-day mission, this utilization and logistics flight delivered a multipurpose logistics module (MPLM) to the ISS with several thousand pounds of new supplies and experiments. In addition, some new orbital replacement units (ORUs) were delivered and stowed externally on the ISS on a special pallet. These ORUs are spares for critical machinery located on the outside of the ISS. During this mission the crew also carried out testing of Shuttle inspection and repair hardware, as well as evaluated operational techniques and concepts for conducting on-orbit inspection and repair.

KENNEDY SPACE CENTER, FLA. - The STS-120 crew is at Kennedy for a crew equipment interface test, or CEIT. Inspecting the thermal protection system, or TPS, tiles under space shuttle Discovery in Orbiter Processing Facility bay 3 are, from left, Expedition 16 Flight Engineer Daniel M. Tani; Mission Specialist Douglas H. Wheelock; Pilot George D. Zamka; Mission Specialist Paolo A. Nespoli (kneeling), a European Space Agency astronaut from Italy; Mission Specialist Scott E. Parazynski; Commander Pamela A. Melroy; Allison Bolinger (kneeling), an EVA technician with NASA; Mission Specialist Stephanie D. Wilson; and Erin Schlichenmaier, with United Space Alliance TPS Engineering. Among the activities standard to a CEIT are harness training, inspection of the thermal protection system and camera operation for planned extravehicular activities, or EVAs. The STS-120 mission will deliver the Harmony module, christened after a school contest, which will provide attachment points for European and Japanese laboratory modules on the International Space Station. Known in technical circles as Node 2, it is similar to the six-sided Unity module that links the U.S. and Russian sections of the station.
