Associated space launch
The Sfera or Geoid series were the first soviet geodetic satellites to improve the accuracy of maps. The development of the satellites started in 1965 at NPO-PM.
COSMOS 911 was lifted into orbit during the mission ‘Kosmos-3M | Sfera 16’, on board a Kosmos-3M space rocket.
The launch took place on May 25, 1977, 11 a.m. from 132/2.
