Kosmos 215
1968-033A
DS-U1-A No. 1 (Kosmos-215) was launched in Apr 1968. It was the first Soviet orbiting astronomical observatory, and carried ultraviolet and X-ray telescopes. It might have preceded the Uhuru satellite in making the first X-ray sky survey, but there was a problem with the aspect information needed to reconstruct the direction the spacecraft was pointing, making it difficult to analyze the data. The satellite also carried photometers for Earth atmospheric profiles, and ocean surface brightness measurements.
