BuAer Committee for Evaluating the Feasibility of Space Rocketry (CEFSR) held joint meeting with AAF representatives to work out joint satellite development program based on BuAer proposal. Nothing resulted until a subsequent Project Rand report and Navy CEFSR proposal were presented to RDB, Committee on Guided Missiles, Technical Evaluation Group in March 1948. References: 17 .

Launched 11:23 local time. Reached 162.9 km. Carried cosmic radiation, pressure, temperature, photo, biological experiments for Naval Research Lab. Took first photograph from 100-mile altitude.

The first Orbiting Solar Observatory (OSO) performed remarkably well in conducting the thirteen different experiments for which it was programmed. Especially relevant to manned space flight were its measurements of solar radiation in high frequency ranges, of cosmic dust effects, and of the thermal properties of spacecraft surface materials.

First generation photo surveillance; return of camera and film by capsule; SAMOS type satellite. Failed to return camera and film. Samos film return project cancelled; remaining 4 cameras placed in warehouse and later used on KH-6 Lanyard. References: 1 , 2 , 5 , 6 , 278 .

Final design approval for Soyuz A spacecraft for earth orbit and circumlunar flight using orbital rendezvous, docking, and refuelling technques. Except for change of orbital module from cylindrical to spherical design, and changes to rendezvous radar tower arrangement, this design was essentially identical to the Soyuz 7K-OK that flew three years later. Additional Details: Korolev approves draft plan for 'Soyuz Complex'. References: 23 .

In a White House release, President Nixon listed six specific objectives for the space program: continued exploration of the moon, exploration of the planets and the universe, substantial reductions in the cost of space operations, extension of man's capability to live and work in space, rapid expansion of the practical applications of space technology, and greater international cooperation in space.

The Skylab rescue mission was a definite NASA commitment. The hardware, procedures, documentation, and training would need to be available immediately after the launch of Skylab 2 for a potential rescue mission. To accomplish this requirement, the rescue mission would be treated as a separate mission in the Skylab Program. The rescue mission would be established as a standing agenda item for major boards and panels, and its status would be reviewed on a regular basis with other missions.
