The Soviet Union successfully launched the Phobos 2 spacecraft to Mars aboard a 198-foot Proton launch vehicle from the Baikonur launch facility. The Phobos 2 launch occurred less than a week after the launch of its companion spacecraft, Phobos 1.

NASA announced that a scientist at the Ames Research Center, Mountain View, California, had developed a new, ground breaking computational model that could accurately simulate the complex, fluctuating airflow within aircraft engine turbines and compressors. The new computational model, developed by NASA scientist, Man Rohm Rai, was expected to generate significant savings for the aircraft engine industry once it became ready for commercial applications. The model performed one of the most complex computer simulations ever undertaken and provided the most accurate calculation to date of air flow within turbines. Engine concepts and designs had been tested primarily by experimental methods, most often by building prototype engines and subjecting them to a battery of tests. Advanced computer techniques were far less expensive and much faster. Current computational work was per-formed on a Cray-2 supercomputer at the new Ames Numerical Aerodynamics Simulation Facility.
