U.S.S.R. launched Cosmos CCCXXVIII from Plesetsk into orbit with 316-km (196.4-mi) apogee, 206-km (128.0-mi) perigee, 89.7-min period, and 72.8° inclination. Satellite reentered April 9. (GSFC SSR, 3/31/70, 4/30/70; SBD, 3/31/70:, 142)
NASA launched series of four Boosted Arcas sounding rockets from TERLS to measure positive and negative ion densities with Gerdien condenser and make simultaneous radio propagation measurements of electron density. NASA also launched Nike-Apache from TERLS carrying Indian experiment to study magnetic field and ionosphere. Rockets and instruments functioned satisfactorily. (NASA Rpts SRL; SR list)
Scientific data on March 7 solar eclipse collected by NASA Aerobee 170 sounding rocket at 173.8-km (108-mi) altitude had been recovered from 1783 m (5850 ft) under water by USN cable-controlled underwater recovery vehicle (CURV 111), Wallops Station announced. NRL payload carrying four cameras had photographed solar flash spectrum in eclipsed sun's chromosphere, but parachute failed to open and payload sank 120 km (75 mi) off coast of Wallops Island, Va. After recovery, water-soaked film was maintained at 275 K (35°F) while scientists devised special processing techniques to restore film. Photos containing prime UV spectrum during total eclipse were salvaged. (WS Release 70-5)
President Nixon announced intention to nominate four assistant directors of NSF: Edward C. Creutz to be Assistant Director for Research; Lloyd E. Humphreys to be Assistant Director for Education; Lewis Levin to be Assistant Director for Institutional Programs; and Thomas B. Owen to be Assistant Director for National and International Programs. Nominations were submitted to Senate March 31, 1970. (PD, 3/30/70, 444; 4/6/70,475)
FAA issuance of advance notice of proposed aircraft engine emission standards, soliciting comments, was announced by Secretary of Transportation John A. Volpe. Studies had shown that one percent of total U.S. air pollution might be attributed to aircraft emissions. (FAA Release 70-28)
March 27-28: NASA launched two Nike-Cajun sounding rockets-Rehbar 21 and Rehbar 22-from Karachi, Pakistan, carrying Pakistan U.K. grenade experiments. Rockets and instruments functioned satisfactorily. (SR list)
