The Gemini IV crew – astronauts Jim McDivitt and Ed White – conducted scientific experiments, including photography of Earth’s weather and terrain, for the remainder of their four-day mission following White’s historic first American spacewalk on 3 June.
Astronauts have been photographing Earth from space since the early Mercury missions beginning in 1961.
