Kosmos 26
Encyclopedia
Kosmos 26 also known as DS-MG #1 was a technology demonstration satellite
which was launched by the Soviet Union
in 1964 as part of the Dnepropetrovsk Sputnik
programme. Its primary mission was to demonstrate an electric gyrodyne orientation system. It also carried a magnetospheric
research package as a secondary payload.
It was launched aboard a Kosmos-2I
63S1 rocket from pad 2 of the Mayak Launch Complex at Kapustin Yar
. The launch occurred at 15:07 GMT on 18 March 1964.
Kosmos 26 was placed into a low Earth orbit
with a perigee
of 268 kilometres (166.5 mi), an apogee
of 376 kilometres (233.6 mi), 48.9 degrees of inclination
, and an orbital period
of 91 minutes. It decayed
from orbit on 28 September 1964. Kosmos 26 was the first of two DS-MG satellites to be launched, the other being Kosmos 49

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....

Dnepropetrovsk Sputnik
Dnepropetrovsk Sputnik , also known as DS, was a series of satellites launched by the Soviet Union between 1961 and 1982. DS satellites were used for a number of missions, including technological and scientific research, and radar tracking targets for anti-satellite weapons and anti-ballistic...

Magnetosphere
A magnetosphere is formed when a stream of charged particles, such as the solar wind, interacts with and is deflected by the intrinsic magnetic field of a planet or similar body. Earth is surrounded by a magnetosphere, as are the other planets with intrinsic magnetic fields: Mercury, Jupiter,...

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 They were superseded by the R-14 derived Kosmos-3 and Kosmos-3M.-References:* http://www.astronautix.com/lvs/koss63s1.htm*...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 period
The orbital period is the time taken for a given object to make one complete orbit about another object.When mentioned without further qualification in astronomy this refers to the sidereal period of an astronomical object, which is calculated with respect to the stars.There are several kinds of...

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...
