Astronauts have to be prepared to make emergency landings in jungles, deserts or oceans. These sunglases are part of the survival kit carried in Gemini IV, which made a historic four-day mission, June 3-6, 1965, with astronauts Jim McDivitt and Edward White. On this mission, White became the first American to make a "spacewalk."
Originally installed in command pilot McDivitt's ejection seat, the survival kit came to the Smithsonian along with the spacecraft in 1967.
