Kosmos 1300 also known as Tselina-D #30 was an electronic signals intelligence satellite launched by the Soviet Union on 8 August 1981 from Plesetsk Cosmodrome Site 32/1 on a Tsyklon-3 rocket.[2]
It is estimated to weigh two tons and have a lifetime of two months. Since it stopped functioning, Kosmos 1300 has become space debris.
On 18 September 2019 at 8:05:55 UTC it was projected to have a 5.6% chance of colliding with the Genesis II commercial space debris at a velocity of 14.6 km/s.[3] [4] The collision would take place over Awasa, Ethiopia.[5] Bigelow Aerospace, the company that made Genesis II, reported afterward that the US Air Force had notified them that there was no collision.[6]
