SEA LAUNCH RECEIVES VEHICLE FOR EUTELSAT-70B MISSION
http://www.sea-launch.com/news_releases/2012/nr_120920.html

Bern, Switzerland, September 20, 2012 – The Ocean Force sea-based transport vessel carrying the Zenit-2S launch vehicle and Block-DM-SL upper stage designated for the EUTELSAT 70B mission departed the port at Oktyabrsky, Ukraine on August 14, 2012 and arrived pier-side at Sea Launch's Home Port facility in Long Beach, California on September 19, 2012. An additional Block DM-SL upper stage, provided by RSC Energia, was also included in this shipment for use on a future mission. The payload accommodations, provided by Boeing Commercial Space Company, will be shipped in early October. The EUTELSAT 70B mission for Eutelsat, one of the world's leading satellite operators, is planned for launch in December 2012.

Sea Launch AG, through Energia Logistics Ltd., has conducted a Hardware Acceptance Review of the Zenit-2S launch vehicle on July 23, 2012 to be utilized in support of the EUTELSAT-70B mission.  Later that week, two Block DM-SL upper stages were similarly accepted.  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 35 vehicle and found that all required acceptance test values were within specification.
Built for Eutelsat by Astrium, an EADS company, the EUTELSAT-70B satellite will weigh approximately 5,250 kilograms (11,574 lbs.) at launch. It is expected to arrive at the Sea Launch facility in October in preparation for the start of standalone and combined spacecraft operations.

Current Mission - EUTELSAT-70B
http://www.sea-launch.com/current_launch_eutelsat-70b.htm

Preparations are currently underway at Sea Launch for the launch of the EUTELSAT-70B spacecraft.  EUTELSAT-70B will be located at 70.5° East longitude in geostationary orbit where it will replace the EUTELSAT-70A satellite. It will be used for a range of professional applications that include government services, broadband access, GSM backhauling and professional video exchanges in Europe, Africa and Central and South-East Asia.

Built for Eutelsat by Astrium, an EADS company, the EUTELSAT-70B satellite will weigh approximately 5,250 kilograms (11,574 lbs.) at launch.

The launch is currently scheduled for early December 2012.  Lift-off will occur at 12:43:55 Pacific Standard Time (20:43:55 UTC, 21:43:55 Paris) at the opening of the 54 minute launch window.

Launch Coverage

Sea Launch will produce live coverage of the EUTELSAT-70B mission, and stream video of the event on this website.  Launch broadcast will begin approximately 15 minutes before scheduled liftoff. Please click here to view our live mission coverage.

Payload

The EUTELSAT-70B satellite is based on the Astrium Eurostar E-3000 platform with a designed in-orbit lifetime exceeding 15 years. The EUTELSAT-70B spacecraft will carry 48- Ku-band transponders. The satellite will replace the EUTELSAT 70A craft and more than double Eutelsat's resources at its 70.5° East longitude location.  Each of the satellite's four high-performance fixed beams will be focused over a distinct zone: Europe, Africa, Central Asia and South-East Asia reaching as far as Australia. Through a high degree of on-board connectivity, clients will be able to use the beams either for regional coverage or to interconnect continents. This will support high-growth services that include secure government communications in Central Asia through hubs located in the region or in Europe, business networks between South-East Asia and Africa, and direct connectivity between Europe and Australia.

EUTELSAT-70B vital statistics:

Platform:  Eurostar E3000
Dimensions, in orbit:
H, 7 m
W, antennas: 8 m
L, solar arrays: 30 m
Mass at Launch: 5,250 kilograms (11,574 lbs.)
Spacecraft power (at end-of-life): 12 kW
Operational Lifetime: 15+ years

EUTELSAT 70B is the 29th Eurostar E3000 delivered, the 7th for Eutelsat, the 3rd to be launched by Sea Launch.

Mission Profile

From its ocean-based launch site located directly on the equator at 154 degrees West longitude, a Zenit-3SL launch vehicle will lift the EUTELSAT-70B spacecraft into an optimized geosynchronous transfer orbit on its way to its final geostationary orbit at 70.5° East longitude.

The Zenit-3SL rocket will begin its ascent phase of flight.  The first stage of the vehicle will separate 2:30 minutes (150 seconds) after liftoff, and the protective payload fairing will be jettisoned 77 seconds later at 3:47 minutes into the flight. The second stage will conduct a 6 minute burn, followed by its separation from the Block DM-SL upper stage.  The Block DM-SL will begin its first of two burns at 8:41 minutes (521 seconds) into the mission, for the duration of 320 seconds.  The upper stage will then shut down for a 36 minute coast period, followed by the start of the second burn at 50 minutes into the mission.  Spacecraft separation is expected at 1:06 minutes after liftoff, over the Indian Ocean.

EUTELSAT-70B SATELLITE ARRIVES AT SEA LAUNCH HOME PORT

BERN, Switzerland, October 17, 2012 - The EUTELSAT-70B satellite of Eutelsat, one of the world's leading satellite operators, has arrived in Long Beach, California and been transported to the Sea Launch "Home Port" facility. Following unloading, the satellite was delivered to the clean room area of the 16-acre sites payload processing facility, where mission operations and integration efforts are now underway.

After standalone spacecraft operations are completed, EUTELSAT-70B will be handed over to Sea Launch's prime contractor, Energia Logistics, Ltd., to be mated with the payload support structure and integrated with the Zenit-3SL launch vehicle before departure to the launch site in November. The launch of the EUTELSAT-70B satellite is scheduled for the early December timeframe.

The EUTELSAT-70B communications satellite departed from the Toulouse, France manufacturing facilities of Astrium, an EADS company on October 15th and arrived at the Long Beach Airport (LGB) on-board an Antonov An-124 cargo aircraft yesterday. It was subsequently transferred via surface roads on an oversized transport vehicle with representatives from Eutelsat, Astrium, and Energia Logistics Ltd. on hand to receive the spacecraft.

EUTELSAT-70B will be located at 70.5° East longitude in geostationary orbit where it will replace EUTELSAT-70A, significantly increasing resources and flexibility at an established orbital location.. This new high-capacity Ku-band satellite will be used for a range of professional applications that include government services, broadband access, GSM backhauling and professional video exchanges in Europe, Africa and Central and South-East Asia.

Sea Launch Prepares for the Launch of EUTELSAT 70B
http://www.sea-launch.com/news_releases/2012/nr_121121.html

BERN, Switzerland, November 21, 2012 — The Sea Launch vessels have departed Sea Launch Home Port in Long Beach, Calif., for the equator, in preparation for the launch of the EUTELSAT 70B satellite for Eutelsat, one of the world's leading satellite operators. Liftoff is planned for 12:43:55 Pacific Standard Time (PST) on Sunday, December 2nd (20:43:55 UTC/GMT, 21:43:55 CET), at the opening of a 54-minute launch window.

Upon their arrival at the launch site at 154 degrees West longitude, the Sea Launch team will initiate a 72-hour countdown. After ballasting the launch platform Odyssey to launch depth, the team will roll out and erect a Zenit-3SL rocket on the launch pad, execute final tests and proceed with fueling operations and launch. Prior to fueling, all personnel on the launch platform will transfer to the Sea Launch Commander for the duration of the mission. The team monitors both marine and launch operations remotely from the ship, positioned about four miles away from the platform.

On launch day, the Zenit-3SL vehicle will lift the 5,250 kilogram (11,574 lbs.) EUTELAT 70B spacecraft into a defined high-perigee geosynchronous transfer orbit.

The EUTELSAT 70B satellite is based on the Astrium Eurostar E-3000 platform with a designed in-orbit lifetime exceeding 15 years. With a 48- Ku-band transponder payload, it will replace the EUTELSAT 70A craft and more than double Eutelsat's resources at its 70.5° East longitude location to provide premium communications services for users in Europe, Africa, Asia and Australia.

If I'm reading the blog correctly ("arrival to the launch site early Friday morning") they should be ballasted down by now. The blog is directly accessible at:
