Explorer I, the first U.S. earth satellite, was launched by a modified Army Ballistic Missile Agency Jupiter-C. Explorer I, developed by the Jet Propulsion Laboratory, carried the U.S.-IGY (International Geophysical Year) experiment of James A. Van Allen and resulted in the discovery of the radiation belt around the earth. References: 1 , 2 , 5 , 6 .

NASA Headquarters announced that the Mercury-Atlas 6 (MA-6) manned orbital mission would be scheduled no earlier than February 13, 1962, and that repair of the Atlas launch vehicle fuel tank leak would be completed well before that time. References: 483 .

The second Martlet One flew for 146 seconds. It rose to an altitude of 27 km and landed about 11 km down range. These two flights were sufficient to prove the launch concept. The initial test series also included several wooden test slugs.

Soviet government approves plan to land cosmonaut on moon by end 1968. N-1 test plan approved, envisioning third quarter 1967 as beginning of flight hardware construction. Fall-back project would be manned circumlunar mission. First manned L1 mission imagined as early as June 1967. First N1 launch by March 1968. References: 72 .

Brezhnev orders a cooperative crash program to build a civilian space station to beat Skylab into orbit. The civilian station (later named Salyut) will use the Almaz spaceframe fitted out with Soyuz functional equipment. Mishin's OIS military station was cancelled and Chelomei's Almaz would continue, but as second priority to the civilian station. The Soyuz 7K-S station ferry, the 7K-ST, would be revised to be a more conservative modification of the Soyuz 7K-OK. The OIS cosmonaut group was incorporated into the Almaz group. References: 76 .

Progress M1 is a modification of the Progress M for the International Space Station. The first such spacecraft was diverted to raise the orbit of Mir. It docked with the unoccupied Mir space station on February 3 at 0802:20 GMT. Burns of its motor to raise Mir's orbit began on February 5 and continued through February 9. Progress M1-1 undocked at 16:33 GMT on April 26 to clear the docking port for Progress M1-2. It was deorbited over the Pacific at 19:27 GMT the same day.
