jsc2019e001293_alt (Feb. 13, 2019) --- NASA Astronaut E. Michael “Mike” Fincke has been assigned to the first flight of Boeing’s CST-100 Starliner. Fincke takes the place of astronaut Eric Boe, originally assigned to the mission in August 2018.

ISS028-E-005662 (27 May 2011) --- A fish-eye lens attached to an electronic still camera was used to capture this image of NASA astronaut Greg Chamitoff during the mission's fourth session of extravehicular activity (EVA) as construction and maintenance continue on the International Space Station. During the seven-hour, 24-minute spacewalk, Chamitoff and astronaut Michael Fincke (visible in the reflections of Chamitoff?s helmet visor), both STS-134 mission specialists, completed the primary objectives for the spacewalk, including stowing the 50-foot-long boom and adding a power and data grapple fixture to make it the Enhanced International Space Station Boom Assembly, available to extend the reach of the space station's robotic arm.
