The stock of Sea Launch orders includes six launches, one of which - the third one this year - will be carried out in November, Energia Space Corporation President and General Designer Vitaly Lopota told reporters on Monday.
"We have contracts for six launches and at least ten are being negotiated," he said in answer to a question from Interfax-AVN. "It takes three years to make the payload, two years the engine and 18 months the carrier rocket. Therefore, customers remained undecided and they were waiting for us to carry out the first three launches [following the Sea Launch company's reorganization]," Lopota said. "We are to perform one more launch this year, tentatively in November," he said.
"In fact, much depends on the supplier of satellites," Lopota said. The Intelsat 21 satellite, launched on Sunday, found itself in orbit with a slight delay, he said "It was due to errors in the satellite's land-based checkout equipment. The carrier rocket and the upper stage did not arouse any questions. The satellite was put into orbit with record-setting accuracy," Lopota said.
Zenit-3SL launches are performed by the Sea Launch international consortium, formed in 1995. Since it was reorganized in 2010, a 95% stake in it has been held by Energia Overseas Limited, the Russian Energia space corporation's subsidiary, 3% by Boeing's subsidiary and 2% by Norway's Aker Solutions ship-building corporation.
The Sea Launch has carried out 33 Zenit-3SL launches from a sea platform in the Pacific Ocean, of which one was partially successful and two were a failure.
