Kosmos 165
Encyclopedia
Kosmos 165 also known as DS-P1-Yu #11 was a radar calibration target satellite
which was used by the Soviet Union
for tests of anti-ballistic missile
s. It was built by the Yuzhnoye Design Bureau
, and launched in 1967 as part of the Dnepropetrovsk Sputnik
programme.
Kosmos 165 was launched using a Kosmos-2I
63SM carrier rocket, which flew from Site 133/1
at Plesetsk Cosmodrome
. The launch occurred at 18:06 GMT on 12 June 1967.
Kosmos 165 separated from its carrier rocket into a low Earth orbit
with a perigee
of 198 kilometres (123 mi), an apogee
of 1399 kilometres (869.3 mi), 81.9 degrees of inclination
, and an orbital period
of 100.84 minutes. It decayed
from orbit on 15 January 1968. Kosmos 165 was the eighth of seventy nine DS-P1-Yu satellites to be launched, and the seventh of seventy two to successfully reach orbit.
Satellite
In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavour. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon....

Anti-ballistic missile
An anti-ballistic missile is a missile designed to counter ballistic missiles .A ballistic missile is used to deliver nuclear, chemical, biological or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" describes any antimissile system designed to counter...

Kosmos-2I
Kosmos-2I is the designation applied to two Soviet carrier rockets, members of the R-12 family, which were used to orbit satellites between 1961 and 1977. They were superseded by the R-14 derived Kosmos-3 and Kosmos-3M.-References:* http://www.astronautix.com/lvs/koss63s1.htm*...

Orbital decay
Orbital decay is the process of prolonged reduction in the altitude of a satellite's orbit.This can be due to drag produced by an atmosphere due to frequent collisions between the satellite and surrounding air molecules. The drag experienced by the object is larger in the case of increased solar...
