| Keywords: Orbiting Solar Observatory 2.gif en The OSO 2 satellite The OSO 2 platform consisted of a sail section which pointed two experiments continuously toward the sun and a wheel section which spun about an axis perpendicular to the pointing direction of the sail and carried six experiments Attitude adjustment was performed by gas jets A pointing control system permitted the pointed experiments to scan the region of the sun in a 40- by 40-arc-min raster pattern Data were simultaneously recorded on tape and transmitted by PCM/PM telemetry A command system provided for 70 ground-based commands The spacecraft performed normally until the pitch gas supply neared exhaustion on November 6 1965 The spacecraft was then placed in a stowed condition The transmitter was commanded on intermittently until March 3 1966 and then on a weekly schedule until June 1 1966 when it ceased operation For more information see A W L Ball Spaceflight v 12 p 244 1970 NASA's HEASARC Observatories Goddard Spaceflight Center Observatories Orbiting Solar Observatories Gallery HEASARC Director Dr Alan P Smale HEASARC Associate Director Dr Roger Brissenden Responsible NASA Official Phil Newman Web Curator Meredith Gibb 2009-02-10 Images produced by NASA are usually free of copyright Experiment Name Spacecraft Name Principal Investigator s Solar X-ray Bursts OSO 2 Chubb Talbot Corona White Light OSO 2 Tousey Richard Zodiacal Light Monitor OSO 2 Ney Edward Cosmic Gamma 100-1000 MeV Detector OSO 2 Leavitt Christopher Gamma Ray OSO 2 Frost Kenneth Solar UV Spectrometer OSO 2 Hallam Kenneth Thermal Radiation Emissivity OSO 2 Neel Carr PD-USGov-Military-Navy Orbiting Solar Observatory | ||||
