USAF Titan III-C booster launched from ETR successfully orbited five unmanned satellites : two Vela nuclear detection satellites and three scientific satellites, Ers-XVIII, Ers-XX, and Ers-XXVII. The 508-lb Velas-improved versions of six Vela payloads previously launched-entered initial elliptical orbits with 69,000-mi (96,642-km) apogee and 5,400-mi (8,690-km) perigee. On April 29, orbit of one Vela was circularized at 69,000-mi (96,642-km) altitude; orbit of second would be circularized May 1. Designed to operate at least 18 mo in orbit, Vela satellites were part of DOD's Vela program to monitor space for violations of nuclear test ban treaty. The 14-and 20-lb scientific satellites contained scientific and engineering experiments to (1) investigate effects of vacuum on characteristics of 16 metals, (2) monitor radiation of Van Allen belts, and (3) measure solar radiation.
