Self-testing-and-repairing (STAR) computer to direct unmanned spacecraft of multiyear missions to outer planets and inter- galactic space had passed preliminary tests and would begin full-scale ground operation at JPL during week, JPL announced. Believed first computer capable of, detecting its own failures and repairing itself, STAR had been developed by Dr. Algirdas A. Avizienis, JPL computer expert, who was trying for 90% probability that it would last 15 yrs, to control operations to Neptune or Pluto in solar system Grand Tours scheduled for late 1970s. During 9-to-11-yr minimum lifetime, STAR would automatically switch on up to three backup units to replace defective parts. By 1974, more modest model might replace defective parts twice for use on shorter missions like one to Jupiter. STAR could also aid in hospital and supersonic-aircraft automation. (JPL Release 532)
