Land Launch, a subsidiary of Sea Launch
, conducts commercial launches of Zenit rocket
s from Baikonur Cosmodrome Site 45
. It operates two-stage Zenit-2SLB and three stage Zenit-3SLB
rockets.
The first launch was conducted on 28 April 2008 at 05:00 GMT, when a Zenit-3SLB was used to place AMOS-3
(AMOS-60) into a geosynchronous orbit
.
The second flight would have launched MEASAT
-3A, a Malaysian communications satellite
, but the spacecraft was damaged by a crane while Land Launch was preparing it for a planned 21 August 2008 launch.
A second launch was completed on February 26, 2009 when Land Launch successfully launched the Telstar 11N mission.
Land Launch missions differ from Sea Launch missions in that the modernised Zenit-3SLB is used, as opposed to the Zenit-3SL
, a smaller and hence lighter payload fairing is used, and the rocket inserts the payload directly into a geosynchronous orbit
, rather than leaving it in a geosynchronous transfer orbit.
