Air Force launched two unidentified satellites from Vandenberg Air Force Base by single Titan IIID booster. First satellite entered orbit with 257-km (160-mi) apogee, 173-km (108-mi) perigee, 88.7- min period, and 96.8° inclination and reentered Sept. 13. Second entered orbit with 501-km (311-mi) apogee, 499-km (310-mi) perigee, 94.5-min period, and 96.1° inclination. (Pres Rpt 73, SBD, 7/13/72, 57; 7/18/72, 78)
Navy's 90.7-metric-ton (100-short-ton) surface effect testcraft SES- 100A made underway test run on Puget Sound, Wash. Advanced design craft was built by Aerojet-General Corp. under direction of Navy's Surface Effect Ships Project Office. Craft was powered by four gas turbines and traveled over water on air cushion propelled by high-capacity waterjets. SES-100A would be used in designing larger surface effect ships capable of high speeds in ocean operations. (SES-100A first test run cover; Navy SES Proj Off)
Experiment to plot evolution of sun and earth over aeons was described in Science by Cornell Univ. astronomers Dr. Carl E. Sagan and Dr. George Mullen. Findings had indicated that sun's energy emission had increased 40% over last 4.5 aeons and would continue to increase until earth temperature reached boiling point, in about 4.5 more aeons. Infrared characteristics of atmospheres of other planets would deter-mine whether life on them, if any, would survive. Mars atmosphere should be approaching required conditions for emergence of life at about same time earth temperature accelerated upward. (Science, 7/7/72, 52-5)
Presidential Prizes for Innovation announced by White House May 21 were similar in objectives to "Olympics of Science" proposed in 1849 by U.S. Commissioner of Patents Thomas Ewbank, patent attorney Harry Goldsmith said in Science article. Ewbank had asked Congress to appropriate $100 000 as permanent "Inventors' Premium Fund," to be distributed once every four years for outstanding contributions by scientists and inventors. Proposal had not been adopted. (Science, 7/7/72, 35)
