Walt Disney's weekly television series aired the first of three programs related to spaceflight. 'Man in Space,' with Wernher Von Braun as technical adviser, drew an estimated audience of 42 million.

Tests were in progress at Langley and Wallops Island on several types of ablating materials under environmental conditions that would be experienced by a spacecraft reentering from orbit. References: 483 .

Carried dog Chernushka, mannequin Ivan Ivanovich, and other biological specimens. Ivanovich was ejected from the capsule and recovered by parachute, and Chernsuhka was successfully recovered with the capsule on March 9, 1961 8:10 GMT.

OSCAR III was launched piggyback with seven United States Air Force satellites. Weight 16.3 kg. It was the first amateur satellite to operate from solar power and relay signals from Earth. OSCAR III was the first true amateur satellite relaying voice contacts in the VHF 2 meter band through a 1 W 50 kHz wide linear transponder (146 MHz uplink and 144 MHz downlink). OSCAR III's transponder lasted 18 days. More than 1000 amateurs in 22 countries communicated through the linear transponder. The two beacon transmitters continued operating for several months.

Note: Designed, built, and tested, a predecssor, OSCAR* was never launched. Similar in design to OSCAR I and II, OSCAR* contained a 250 mW beacon with phase-coherent keying. OSCAR* was never launched as the workers decided to focus their efforts on the first relay satellite -- OSCAR III. References: 1 , 2 , 5 , 6 .

A team of engineers from Douglas Aircraft Company, headed by Jack Bromberg, presented a technical briefing and cost proposal to Associate Administrator for Manned Space Flight George E. Mueller on the company's design on the airlock for the AAP. Mueller observed that Douglas' idea for a 30-day capability seemed technically sound. He expressed strong interest in the AAP spent-stage experiment because it would establish a solid basis for space station requirements and definition. However, he cautioned that he had not received definite approval from either the Administrator, James E. Webb, or his deputy, Robert C. Seamans, Jr., on the spent-stage concept and admitted that he had 'some selling to do.'
