Kosmos 335 (ru|Космос 335 meaning Cosmos 335), also known as DS-U1-R No.1, was a Soviet satellite which was launched in 1970 as part of the Dnepropetrovsk Sputnik programme. It was a 295kg (650lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used to study spectral ranges in the Earth's atmosphere.[1]
A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 335 into orbit. The launch took place from Site 86/4 at Kapustin Yar.[2] The launch occurred at 22:24:48 UTC on 24 April 1970, and resulted in the successfully insertion of the satellite into low Earth orbit.[3] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1970-035A.[4] The North American Aerospace Defense Command assigned it the catalogue number 04380.
Kosmos 335 was one of the DS-U1-R satellites.[1] [5] It was operated in an orbit with a perigee of, an apogee of, 48.4 degrees of inclination, and an orbital period of 90.9 minutes. It completed operations on 20 June 1970.[6] On 22 June 1970, it decayed from orbit and reentered the atmosphere.[7]
