Anik E1

 1991-067A


The first Anik E satellite to be built, E-1 was launched second. In Jan 1994, its attitude control system failed in a similar way to that of E-2, but control of the spacecraft was recovered. In 1996, one of the two solar arrays failed, reducing its capacity to 9 C-band and 10 Ku-band channels.

Kosmos 2390

 2002-036A


A Kosmos-3M (11K65M) rocket was launched from Plesetsk on Jul 8 and placed a pair of Russian Defense Ministry satellites, Kosmos-2390 and Kosmos-2391, in 1466 x 1507 km x 82.5 deg orbits. The launch was a surprise, as it doesn't fit the established profile of any existing Russian military system. Aleksandr Zhelezneyakov's site, www.cosmoworld.ru, was the first to report the pair as Strela-3 satellites.
