SCBruce McCandless II performed the first ever untethered spacewalk on 7th February 1984. Using the Manned Manoeuvring Unit (MMU), he veered around 100 metres away from Space Shuttle Challenger.
The MMU used nitrogen gas propulsion to control the thrust and orientation of the astronaut. The photos, taken by astronaut Robert L. Stewart aboard the shuttle, capture the vastness and solitude of space. McCandless is depicted floating small and alone against the curve of Earth and the darkness of space beyond.
