McCandless, who died Thursday, became the first astronaut to fly in space without being harnessed to a space vessel on Feb. 7, 1984, while on a mission aboard the space shuttle Challenger. Other astronauts on the mission used a 70mm camera to capture the moment in a now-iconic photograph, NASA said in a release.
