Willis B. Foster, Director of Manned Space Science in the Office of Space Science and Applications, distributed a preliminary draft report of the Ad Hoc Astronomy Panel of the Orbiting Research Laboratory (ORL). The panel, which met on 26 October 1963 and again on 24 June 1964, was created to sound out the American scientific community on the validity of manned astronomy in space and to define astronomy objectives for the ORL, mission.

Command number 655-268 was issued by Central Committee of Communist Party. Chelomei was to develop the LK-1 for the manned lunar flyby while Korolev was to develop the N1-L3 for the manned lunar landing. First launch of the N1 was to be by the first quarter 1966, with manned lunar landings in 1967 to 1968. Reprioritization led to work being stopped on Korolev's Zvezda 6 man orbiting weapons platform by mid-1965, after a huge mockup had been built. Chelomei as usual issued the advanced project for the LK-1 on the same day. The decree also ordered development of the three-stage version of his Proton UR-500 to boost the LK-1 around the moon.

NASA named three firms, Bendix Systems Division, TRW Systems Group, and Space-General Corporation to design prototypes of the Apollo Lunar Surface Experiments Package (ALSEP). Each company received a $500,000, six-month contract. After delivery of the prototypes, MSC would select one of the three to develop the ALSEP flight hardware. References: 16 .
Biological research. Scientists from the U.S.S.R., the U.S., Czechoslovakia, France, Hungary, Poland, Romania, Bulgaria and the German Democratic Republic conducted experiments in physics and biology on the mission. The biosatellite was recovered at 51 deg 53 min N, 61 deg 30 min E, near Kustanay in Central Asia after remaining in orbit for 18.5 days. Additional Details: Cosmos 936.
