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 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.
