U.S.S.R. successfully launched Cosmos CCVIII. Orbital parameters: apogee, 278 km (173 mi) ; perigee, 202 km (126 mi) ; period, 89.2 min; and inclination, 64.9°. Satellite reentered April 2. (UPI, NYT, 3/22/68, 5; SBD, 3/22/68, 125; GSFC SSR, 3/31/68; 4/15/68)
NASA Nike-Tomahawk sounding rocket launched from Churchill Research Range carried Univ. of Maryland experiment to 150-mi (241- km) altitude to study dissipation processes and electron acceleration mechanisms in aurora. Four experiments measured energy spectrum of electrons from 1 ev to 200 key. Photometers, UV emissions, and plasma probes were included. Three of four electron experiments returned data on energy spectra; no data were acquired from optical and plasma experiments because clamshell nose cone failed to deploy. (NASA Rpt SRL)
XB-70 research aircraft was flown to 15,500-mi altitude by Col. Joseph F. Cotton (USAF) and NASA test pilot Fitzhugh L. Fulton, Jr. Primary goals were not achieved because main landing gear valve malfunctioned. Low-speed, gear-down handling qualities, propulsion system, and performance tests were accomplished during 2-hr 30-min flight from Edwards AFB. (XB-70 Proj Off)
