1968 Press Photo Volunteer Junior Astronauts line up at the Douglas Space Cabin.

Four "Junior Astronauts" lined up outside their "spaceship" are, from left: Jack Angarin, 22; Bob Zeuschner, 26; Guy King, 25; and Dennis Giroux, 28. They have volunteered to spend 60 days in the 12-foot-diameter, 40-foot-long chamber. Their "flight" simulates a one-to-three year space mission, with 60-day resupply, that might be flown in the 1970s.
