NASA announced that the launch of HEAO-A (the high-energy astronomy observatory) originally scheduled for April 1977 had been set for Aug. 12. Problems with the spacecraft's gyroscopes, required for attitude control, had caused the delay. Analysis and testing had produced design changes to improve gyroscope reliability for the expected 6mo mission lifetime. HEAO-A would be first of three astrophysical observatories orbited over the next 3yr to study radiation from stellar sources throughout the universe. (NASA Release 77-156)
NASA announced it would hold a briefing at Hq Aug. 4 on the scientific studies to be conducted by the Voyager spacecraft scheduled for launch later this year toward the giant planets Jupiter, Saturn, and possibly Uranus. Participants in the briefing would be Dr. Noel W. Hinners, NASA's associate administrator for space science; Dr. Edward Stone, Calif. Inst. of Technology, project scientist; John Casani of JPL, project manager; Dr. Bradford A. Smith, Univ. of Ariz., leader of the imaging science team for the Voyager project; and Dr. James W. Warwick, Univ. of Colo., principal investigator for planetary radioastronomy. (NASA Release 77-155)
