Initially, the launch was planned for April 16. However, due to technical reasons the launch had to be postponed.
During a "dry" conveyance to the launch position, technical notes concerning the erection of the rocket were recorded.
The Zenit-3SL rocket consists of the Zenit-2S booster stages made by the Ukraine-based design bureau Yuzhmash (Dnipropetrovsk), and the DM-SL booster made by Russia's space rocket corporation Energia.
The Eutelsat spacecraft is based on the Eurostar E3000 platform. It is made by the Airbus Defense and Space Company and is designed for operation in the commercial C, Ku, and Ka ranges. The satellite will make it possible to diversify services being rendered to internet providers, government agencies, and transmitting stations which operate in Latin America, Europe, Africa, the Middle East, and Central Asia. The designed life of the Eutelsat-3B is more than 15 years.
The Sea Launch multinational company was founded in 1995 with the participation of the American Boeing Company, Russia's space rocket corporation Energia, the Norwegian Kvaerner Company, and Ukraine's enterprises such as Yuzhnoye (southern) and Yuzhmash (southern engineering) design bureaus.
This is the first-ever commercial international project for the development and operation of a sea-launch space rocket complex. The Company and a floating space-launch platform were brought into being with a view to implementing the idea of launching space rockets from the equator. Thirty-five launches of Zenit-3SL rockets were carried out under the Sea Launch program with 32 of them being successful.
