Goddard's doctoral thesis is on a radio principle very similar to the transistor. But his secret passion remains rocketry and space travel. After a one year fellowship at Princeton, Goddard will return to Clark to teach as an assistant professor of physics. References: 377 .

Goddard receives $ 20,000 from US Army Signal Corps for rocket development. Together with his assistant Clarence N Hickman he develops a prototype of the World War II bazooka at the Mount Wilson Observatory in California. References: 377 , 482 .

The coordinated program to help European nations recover from ravages of war will cost $13 billion by 1951.

The purposes of the AAP 1/AAP-2 mission were (1) to conduct a low-altitude, low-inclination, Earth- orbital mission with a crew of three men, open ended to 28 days' duration, using a spent S-IVB stage as an OWS; (2) to provide for reactivation and reuse of the OWS during subsequent missions occurring up to 1 year later; (3) to conduct inflight experiments in the areas of science, applications, technology, engineering, and medicine; and (4) to qualify man, evaluate his support requirements, and determine human task performance capability on long-duration manned space flight missions. Additional Details: The purposes of the AAP 1/AAP-2 mission were defined..

Meteosat 2 is a geostationary meteorological satellite, operating within the world wide network of the World Weather Watch of WMO. Its main missions are: Imaging in the visible, IR and water vapour region of the spectrum; data reception from so-called dat a collection platforms (DCPs); data distribution to meteorological services and other interested parties (research institutes etc). Launch time 1233:03 UT. Geostationary position 0 deg E. Designator ESA/81/03. References: 1 , 2 , 5 , 6 .

Launch vehicle test payload. Technological capsule. ESA registration ESA/81/02. Launch time 1233:03 UT. The technological capsule, equipped with batteries for a lifetime of about six orbital revolutions, transmits to earth technological data about test flight L-03 of ARIANE. After di scharge of the battery the capsule will stop its transmissions and remain in orbit on inactive status. Frequency 136-138 MHz (transmission until 65h after launch only). Projected time of reentry 1986. References: 1 , 2 , 5 , 6 .
