Page "Extra-vehicular activity" Paragraph 18

The first EVA in deep space was made on August 5, 1971, by American Al Worden, to retrieve a film and data recording canister from the Apollo 15 Service Module on the return trip from the Moon.

Worden was assisted by James Irwin, doing a standup EVA in the Command Module hatch.

This was repeated by Ken Mattingly and Charles Duke on Apollo 16, and by Ronald Evans and Harrison Schmitt on Apollo 17.
