Beskrivning : This mission was the third in the OAO program and its second successful spacecraft to observe the celestial sphere from above the earth`s atmosphere. A UV telescope with a spectrometer measured high-resolution spectra of stars, galaxies, and planets with the main emphasis on the determination of interstellar absorption lines. Three X-ray telescopes and a collimated proportional counter provided measurements of celestial X-ray sources and interstellar absorption.
