The U.S.S.R. launched Meteor 17 meteorological satellite from Plesetsk into orbit with a 892-km apogee, 863-km perigee, 102.5-min period, and 81.2° inclination. The satellite carried equipment to obtain cloud- and snow-cover images on the sunward and shadow sides of the globe as well as data on thermal energy reflected and emitted by the earth and the atmosphere.

NASA's Plum Brook Station had tested an experimental hypersonic ramjet engine in a hypersonic wind tunnel with simulated flight conditions of mach 5, 6, and 7, Lewis Research Center announced. The water-cooled ramjet engine, a cooperative effort of LeRC and Garrett Corp., was de-signed to operate efficiently from mach 4 to mach 8 by using hydrogen fuel, a translating spike inlet, and both subsonic and supersonic combustion modes. The tests had yielded valuable basic information for possible future aircraft development. (LeRC Release 74-14)
