Space astrophysical observatory 'Orion-2'
The paper presents a detailed description of the Orion 2 spaceobservatory, its systems, instruments, and operational modes.Operational principles of the observatory in orbit are outlined, and thescientific devices are discussed, including the Meniscus telescope,slitless diffraction spectrographs, and X-ray chambers. The design ofthe observatory is described along with its construction, stellarsensors, solar transducer, and sighting system. Functional schemes arepresented for the astronavigation system, six-wheel stabilization, andelectrical system. The procedure for conducting experiments is outlined,photographic materials used during the mission are described, and groundtests are summarized. Some results obtained by the observatory arediscussed, especially UV spectrograms of hot and cold stars.
