The cosmonauts and VVS contingent prepare to depart to Baikonur - altogether 50 people on a single An-10 flight. Kamanin has started training a group of cosmonauts for the 15-day Voskhod-3 mission: Volynov, Beregovoi, Shatalov, Demin, and Artyukhin. Katys briefs Kamanin on his work together with Equipment Institute of the Academy of Sciences in preparing scientific experiments to be conducted on the next flight. Later Kamanin talks with his superiors about three candidates for future physician-cosmonaut missions. Voskresensky is the leading candidate. He specialises in research on the effects of zero-gravity on organisms, has published over thirty papers, and knows English. Yaroshenko is completing work on methods for conducting surgical operations in zero gravity. Ivanov conducts psychological studies on the impact of the spaceflight environment.
