Cosmos 483 was launched by U.S.S.R. from Plesetsk into orbit with 290-km (180.2-mi) apogee, 203-km (126.1-mi) perigee, 89.5- min period, and 72.8° inclination. Satellite reentered April 15. (GSFC SSR, 4/20/72; Sov Aero, 5/1/72, 9)
NASA launched two Nike-Javelin III sounding rockets carrying Naval Research Laboratory cesium cloud experiments from Wallops Station at 5:04 am and 5:06 am EST. Huge pinkish-white clouds were formed and were visible along East Coast. Launches were last in series of five that began March 25 to study atmosphere in 97-km (60-mi) region.

April 3-20: Ames Research Center's Convair 990 flying laboratory participated in Arctic Ice Dynamic Joint Experiment (AIDJEX), inter- national cooperative research program to obtain quantitative data on interactions of pack ice and ocean currents. AIDJEX team of scientists from U.S., Canada, and Japan made studies from test site in Beaufort Sea north of Point Barrow, Alaska. Convair 990 carried microwave radiometers, infrared imager, infrared radiometers, and laser geodolite above site in precise pattern to obtain remotely sensed data for correlation with measurements on ground. Data would help solve problems related to Arctic ice cover, its influence on global ocean circulation, and ship passage through ice-covered seas. (ARC Astrogram, 3/30/72, 1; ARC Release 72-22)
