It was a {{convert|325|kg|adj=on}} spacecraft,[1] which was built by the Yuzhnoye Design Bureau, and was used to study the effects on radio waves of passing through the ionosphere.[1] A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 259 into low Earth orbit. The launch took place from Site 86/4 at Kapustin Yar.[2] The launch occurred at 05:09:54 UTC on 14 December 1968, and resulted in the successful insertion of the satellite into orbit.[3] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1968-113A.[4] The North American Aerospace Defense Command assigned it the catalogue number 03612. Kosmos 259 was the third and final DS-U2-I satellite to be launched.[1][5] It was operated in an orbit with a perigee of {{convert|212|km}}, an apogee of {{convert|1210|km}}, 48.4 degrees of inclination, and an orbital period of 99 minutes.[9] On 5 May 1969, it decayed from orbit and reentered the atmosphere.[6] See also{{Portal|Spaceflight}}
