ISS041-E-067002 (7 Oct. 2014) --- NASA astronaut Reid Wiseman, Expedition 41 flight engineer, participates in a session of extravehicular activity (EVA) as work continues on the International Space Station. During the six-hour, 13-minute spacewalk, Wiseman and European Space Agency astronaut Alexander Gerst (out of frame), flight engineer, worked outside the space station's Quest airlock relocating a failed cooling pump to external stowage and installing gear that provides back up power to external robotics equipment.

iss041e096097 (10/23/2014) — Photo documentation of the Electromagnetic Levitator (EML) in the Columbus module of the International Space Station (ISS). The EML multi-user facility is designed for containerless materials processing in space.

ISS040-E-050780 (7 July 2014) --- One of the Expedition 40 crew members aboard the International Space Station, flying 226 nautical miles above the Indian Ocean, south of Australia, recorded this image of Aurora Australis or the Southern Lights on July 7, 2014.

ISS040-E-040103 (5 July 2014) --- As the International Space Station was flying at an altitude of 226 nautical miles on July 5 above a point in the southern Indian Ocean near South Africa's Prince Edwards Islands, one of the Expedition 40 crew members photographed this image of Aurora Australis.

ISS040-E-043231 (6 July 2014) --- As in the case of many previous space missions, the Great Salt Lake in Utah serves as a striking visual marker for the Expedition 40 crew members orbiting 222 nautical miles over North America aboard the International Space Station. A 200mm focal length was used to capture the image. A sharp line across the lake's center is caused by the restriction in water flow from the railroad causeway. The eye-catching colors of the lake stem from the fact that Great Salt Lake is hypersaline, typically 3-5 times saltier than the ocean.

iss056e181703 (9/21/2018) --- European Space Agency (ESA) astronaut Alexander Gerst holding Earth Guardian Seeds, in the Cupola Module aboard the International Space Station (ISS). ESA-EPO-Gerst Earth Guardian Seeds (Earth Guardian Seeds) experiment is intended to teach students the importance of biodiversity and the protection of species, as well as, inspire curiosity for the natural and environmental sciences. Wildflower seeds are flown to the International Space Station (ISS), returned to Earth, and distributed to schools in Germany. The seeds are grown and their development is compared to grown seeds that remained on Earth.

ISS041-E-067002 (7 Oct. 2014) --- NASA astronaut Reid Wiseman, Expedition 41 flight engineer, participates in a session of extravehicular activity (EVA) as work continues on the International Space Station. During the six-hour, 13-minute spacewalk, Wiseman and European Space Agency astronaut Alexander Gerst (out of frame), flight engineer, worked outside the space station's Quest airlock relocating a failed cooling pump to external stowage and installing gear that provides back up power to external robotics equipment.

iss041e000170 (9/11/2020) --- A view of the Columbus Module aboard the International Space Stations (ISS). The Columbus laboratory is Europe’s largest contribution to the International Space Station. Columbus is a multifunctional pressurized laboratory permanently attached to the Harmony Module. The lab allows researchers on the ground, aided by the station’s crew, to conduct a wide variety of research in a weightless environment. In addition, experiments and applications can be conducted outside the module in the vacuum of space, thanks to four exterior mounting platforms that can accommodate external payloads in space science, Earth observation and technology.

ISS040-E-008274 (7 June 2014) --- The moon rising over the southern Pacific Ocean is featured in this image photographed by an Expedition 40 crew member on the International Space Station. A portion of the station?s solar array panels are visible at right.

ISS040-E-006897 (3 June 2014) --- European Space Agency astronaut Alexander Gerst, Expedition 40 flight engineer, performs an Ocular Health (OH) examination in the Destiny laboratory of the International Space Station.
