The Zenit is a pretty neat launcher - the RD-170 onwards series of engines are amazing. I wonder if multi-core versions of this launcher have ever been looked at? 'Strapping' 3x cores in a row like Delta IV-H or Falcon Heavy? Or 5x stages with a cryogenic upper stage to get 100 tons into LEO? Sounds like a good topic for a spinoff thread

Boeing-built Intelsat 21 Satellite Sends Initial Signals from Space

2nd 702MP satellite healthy, in transfer orbit after Aug. 18 launch

EL SEGUNDO, Calif., Aug. 19, 2012 -- Intelsat 21, the second Boeing [NYSE: BA] 702 Medium Power (MP) satellite, has begun sending signals from its preliminary transfer orbit in space.

Approximately 55 minutes following liftoff at 11:55 p.m. Pacific time on Aug. 18, Boeing's Mission Control Center in El Segundo received initial data from the satellite and confirmed that it was functioning normally. The satellite, launched aboard a Sea Launch Zenit-3SL rocket from the Pacific Ocean, is the second of four 702MP satellites Boeing is building for satellite services provider Intelsat.

"Intelsat 21 will continue to serve our customers in the thriving media programming sector in Latin America," said Thierry Guillemin, Intelsat senior vice president and chief technical officer. "And with C- and Ku-band services designed to span four continents, it will enhance Intelsat's global mobility network by supporting the connectivity requirements of our maritime and aeronautical customers across the South Atlantic."

Replacing Intelsat 9 at 302 degrees east longitude, the high-powered Intelsat 21 satellite will complete checkout and testing before entering service later this year.

"Boeing drew on the proven heritage of the Boeing 702 product line and a modular-design approach for the 702MP to enable faster delivery at a lower cost," said Craig Cooning, chief executive officer of Boeing Satellite Systems International and vice president and general manager of Boeing Space & Intelligence Systems. "As we fulfill the four-satellite order Intelsat placed with us in 2009, we will continue to deliver a quality product."

Intelsat is the leading provider of satellite services worldwide. For over 45 years, Intelsat has been delivering information and entertainment for many of the world’s leading media and network companies, multinational corporations, Internet service providers and governmental agencies. Intelsat's satellite, teleport and fiber infrastructure is unmatched in the industry, setting the standard for transmissions of video, data and voice services. From the globalization of content and the proliferation of HD, to the expansion of cellular networks and broadband access, with Intelsat, advanced communications anywhere in the world are closer, by far.

Well, after several elsets, things are shaping up:

2012-045B/38750 at epoch Aug 19, 1438UTC in 287.3 x 35702.9km x 0.12° (could be the spacecraft)

2012-045A/38749 at epoch Aug 19, 1422UTC in 255.2 x 35583.0km x 0.13° (could be Block-DM-SL)

Intelsat 21 Launch Success Refreshes Capacity for Leading Latin America Video Neighborhood; Furthers Mobility Coverage Across South Atlantic Ocean

Luxembourg, 19 August 2012

Intelsat S.A., the world’s leading provider of satellite services, announced today that a Sea Launch Zenit 3SL launch vehicle successfully launched the Intelsat 21 satellite from a mobile platform in the equatorial Pacific Ocean. Liftoff occurred at 2:55 a.m. EDT. Thirty minutes after launch, at 3:25 a.m. EDT, the Intelsat 21 satellite separated from the rocket’s upper stage and continued its ascent toward geosynchronous orbit. Signal acquisition occurred at 3:52 a.m. EDT.

Intelsat 21 will serve the leading direct-to-home (DTH) and cable programmers in Latin America. Replacing Intelsat 9, the satellite is designed to provide more than 18 years of service and features C-band services for South America, North America and Europe, and Ku-band services for North America, the Caribbean, Brazil, Europe and Western Africa.

Intelsat 21 also features a Ku-band mobility beam, providing coverage across the South Atlantic to Intelsat’s maritime and aeronautical customers. Intelsat’s global broadband mobility platform is scheduled for completion in early 2013. The satellite’s final orbital location will be 302°East.

“Intelsat 21 will refresh capacity for Latin America’s premier video neighborhood and will offer vital communications services spanning four continents,” said Intelsat CEO David McGlade. “In addition, Intelsat 21 continues deployment of Intelsat’s Ku-band global broadband mobility platform, designed to support the rapid growth in demand for broadband connectivity for maritime and aeronautical applications.”

Built by Boeing Satellite Systems, Intelsat 21 is the fourth of five Intelsat launches planned for 2012. Intelsat 23 is scheduled for launch later this year aboard a Proton launch vehicle from Baikonur Cosmodrome in Kazakhstan.

Sea Launch AG, through Energia Logistics Ltd., has conducted a 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.
