Special Achievement Awards to Naval Research Laboratory scientists Richard L. Staler and Dr. Bruce J. Faraday for technique to prevent solar-cell overheating in satellite power systems were announced by NRL. Technique improved satellite efficiency and could extend satellite life by fabricating solar panels of unique materials that allowed cooler operation. Technique-already incorporated on NRL satellites built by NRL Space Systems Div.-increased available power, decreased satellite weight, and promised cost savings for building and operating solar-cell power-supply subsystems.

NASA awarded three letter contracts for design of modifications to quiet engines and reduce exhaust emissions of U.S. commercial jet aircraft, United Aircraft Corp, Pratt & Whitney Div, received $1,2 million to modify JT3D and JT8D engines and McDonnell Douglas Corp. and Boeing Co. each received $800 000 to propose methods for acoustically treating nacelles to absorb fan noise. Work would be noncompetitive. (NASA Release 72-166)
Univ. of California at Los Angeles reported that test conducted with 3- mev electron microscope in Toulouse, France, had contradicted theory that at electron energies high enough to magnify specimens down to molecular level specimen would be so severely damaged that results would be useless. Test had shown reverse to be true. As energy of microscope's electron beam increased, extent of damage had decreased. (Sullivan, NYT, 8/16/72, 14)
President Nixon informed Congress of plans for six-month International Exposition on the Environment to be held in Spokane, Wash., in 1974. (PD, 8/21/72, 1237)
