S66-18602 (16 March 1966) --- Astronauts Neil A. Armstrong and David R. Scott sit with their spacecraft hatches open while awaiting the arrival of the recovery ship, the USS Leonard F. Mason after the successful completion of their Gemini-8 mission. They are assisted by U.S. Navy divers. The overhead view shows the Gemini-8 spacecraft with the yellow flotation collar attached to stabilize the spacecraft in choppy seas. The green marker dye is highly visible from the air and is used as a locating aid. Photo credit: NASA
