...Hardware Acceptance Review of the Zenit-2S launch vehicle to be used in support of the Intelsat 21 mission. A team of specialists from the Chief System Engineer’s Office at Energia Logistics Ltd., together with specialists from RSC Energia, reviewed all of the acceptance data for the Zenit-2S #SL 34 vehicle and found that all required acceptance test values were within specification.

The Ocean Force sea-based transport vessel carrying the Zenit-2S launch vehicle designated for Intelsat 21 departed the port at Oktyabrsky, Ukraine, on May 18, 2012, and is scheduled to arrive pier-side at Sea Launch’s Home Port facility in Long Beach, California on June 29, 2012. The Block DM-SL upper stage designated for Intelsat 21, provided by RSC Energia, was shipped to Home Port earlier this year and the Payload Accommodations, provided by Boeing Commercial Space Company, will be shipped in mid-June. The Intelsat 21 mission is planned for launch in August 2012.

Built by Boeing Satellite Systems Inc., the Intelsat 21 satellite will weigh approximately 5,984 kilograms (13,192 lbs.) at launch. It is expected to arrive at the Sea Launch facility in late June or early July in preparation for the start of standalone and combined spacecraft operations.
