http://www.sea-launch.com/news_releases/2012/nr_120217.html

BERN, Switzerland, February 17, 2012 - Sea Launch AG, through Energia Logistics Ltd., has conducted a Hardware Acceptance Review of the Zenit-2S launch vehicle to be utilized in support of the Intelsat 19 mission. A team of specialists from the Chief Engineer's Office at Energia Logistics Ltd., together with specialists from RSC Energia, reviewed all of the acceptance data for the Zenit-2S #SL33 vehicle and found that all required acceptance test values were within specification.

The Condock V sea-based transport vessel carrying the Zenit-2S launch vehicle designated for Intelsat 19 departed the port at Oktyabrsky, Ukraine on February 17, 2012 and is scheduled to arrive pier-side at Sea Launch's Home Port facility in Long Beach, California on March 30, 2012. The Block DM-SL upper stage designated for Intelsat 19, provided by RSC Energia, was shipped to Home Port last year and the Payload Accommodations, provided by Boeing Commercial Space Company, will be shipped in early March. The Intelsat 19 mission is planned for launch in May 2012.

Built by Space Systems Loral, the Intelsat 19 satellite will weigh approximately 5,600 kilograms (12,345 lbs.) at launch. It is expected to arrive at the Sea Launch facility during the last week of March in preparation for the start of standalone and combined spacecraft operations.

Начало миссии Intelsat 19 перенесено с 21-23 марта на 15-20 дней. Пуск, скорее всего, тоже сдвинется вправо

Народ должен был улететь в США на этой неделе в расчете на пуск 5 мая. Мне сказали, что начало командировки задерживается на две недели. Это бьется с информацией о том, что пуск теперь планируется не ранее 20 мая.

Проблема с платформой, задержка 2-3 недели.

... проблема связана с негерметичностью понтонов, из-за которой экологическая служба не выпускает платформу из порта в Лонг-Бич

Новая дата начала миссии 12 апреля.

Intelsat 19[/size]


Intelsat 19 [SSL]

Space Systems/Loral announced in June 2009 that it has been awarded a contract to provide two new satellites to Intelsat, the leading provider of Fixed Satellite Services (FSS) worldwide. The two satellites, Intelsat 19 and Intelsat 20, will be among the most powerful FSS satellites ever built with unprecedented capacity to provide services for broadband, video, and voice applications.

Intelsat 19 and Intelsat 20 will replace existing satellites that currently provide services to five continents and will offer services for broadcast television and telecommunications. The satellites also will have the capacity to support mobile communications and higher data rate network services.

Intelsat 19 is the 36th satellite that Space Systems/Loral will provide to Intelsat and it is scheduled for launch in 2011. It will replace the Intelsat 8 satellite at 166 degrees East longitude. The satellite's C-band capacity will provide enhanced distribution of content throughout Asia-Pacific with reach to the Western United States. The increased Ku-band capacity, optimized to distribute services to Australia, will also support demand for mobility and enterprise network applications across the Asia-Pacific region.

Both satellites are built on the LS-1300 satellite platform, which provides the flexibility for a broad range of applications. They are designed to provide service for at least 15 years.

Автор статьи не знает что платформы нет в порту.

Мне сказали, что платформа находилась на обслуживании в сухом доке на побережье Индийского океана. После отплытия в США у нее обнаружилась проблема с гребным мотором. Пришлось возвращаться обратно для ремонта.

More immediately, the Sea Launch platform, which is a converted oil rig, will be sent either to Malaysia or Singapore for scheduled maintenance.

Sea Launch President Kjell Karlsen said the launch platform will be put into dry dock to replace its engines and clean its pontoons, and is scheduled to return to the company's Long Beach, Calif., operations center by January. "I look at this as a big non-event," Karlsen said in a Sept. 12 interview. "It is something that needs to be done every 15 years and will result in the platform's being more fuel efficient afterward."

Following the Intelsat 19 launch the Sea Launch command ship will undergo three weeks of maintenance, probably in Vancouver, Canada.

In the third quarter of 2012, Sea Launch has scheduled the flight of the Intelsat 21 satellite from the Pacific Ocean site. Intelsat and Eutelsat satellites are slated for launches in 2013 as well. The current 2012 manifest of two Intelsat spacecraft and one for Eutelsat is likely to remain where it is because of a lack of rocket hardware.

Zenit booster delivered for next Sea Launch mission

The Ukrainian Zenit rocket for Sea Launch's next commercial launch has arrived at the firm's California home base for final assembly, a company spokesperson said Thursday.

The Zenit 3SL rocket will launch the Intelsat 19 satellite in late May from the Odyssey launch platform, a modified North Sea drilling rig. Odyssey is steaming back to Sea Launch's home port from Malaysia after dry-docking for a required 15-year maintenance regimen.

The mobile platform and the Sea Launch Commander control ship launch Zenit rockets from the Pacific Ocean, along the equator at 154 degrees west longitude. The position provides a performance boost for equatorial orbits due to the speed of Earth's rotation.

Sea Launch expects Odyssey to arrive in Long Beach, Calif., later this month after stopping in Guam to offload an ill sailor and bunker, according to Peter Stier, a company spokesperson.

Kjell Karlsen, president of Sea Launch, said the Sea Launch Commander returned to Long Beach in March from a dry dock in Vancouver, British Columbia.

The Zenit rocket's two Ukrainian stages, designed by Yuzhnoye and built by Yuzhmash, arrived at Sea Launch's Long Beach home port April 3. Workers removed the rocket stages April 4 from the transport ship, which departed Feb. 17 from the port at Oktyabrsky, Ukraine.

The upcoming launch, scheduled for as soon as late May, will be Sea Launch's second flight from the ocean-based Odyssey platform since the company was reorganized under Chapter 11 bankruptcy. Sea Launch orbited the Atlantic Bird 7 communications satellite for Eutelsat in September from the Pacific launch site, and a Land Launch Zenit rocket delivered the Intelsat 18 craft to space from the Baikonur Cosmodrome in Kazakhstan in October.

"It just proved that Sea Launch took a little break off," Karlsen said. "We're not a new entrant. We're a proven launch provider."

Sea Launch has launched Zenit rockets 31 times from the equatorial Pacific Ocean.

The Block DM-SL upper stage for the Intelsat 19 launch was delivered to Long Beach last year, according to Sea Launch. The upper stage is produced by Energia, the principal owner of the reorganized Sea Launch company which also oversees the overall Zenit supply chain.

Delayed deliveries of rocket hardware were cited by Sea Launch as a contributing cause of its bankruptcy. Now with direct control of the Zenit supply chain, Energia officials say they can ensure shipments arrive in California from Russia and Ukraine on time.

Sea Launch relocated its headquarters from Long Beach to Switzerland during the Chapter 11 process.

The Intelsat 19 satellite for Sea Launch's next mission will be shipped later this month to Long Beach from its Space Systems/Loral factory in Palo Alto, Calif.

Intelsat 19 will provide C-band and Ku-band communications services to the Asia-Pacific region, reaching the United States and Australia.

Another Intelsat satellite will lift off on another Sea Launch Zenit 3SL rocket in late summer. Intelsat 21, built by Boeing Satellite Systems Inc., will beam video distribution and direct-to-home broadcasting to users in Latin America for up to 15 years.

According to Stier, the Block DM upper stage for the Intelsat 21 mission is now in Long Beach. The Ukrainian components of the booster will arrive in June.

Sea Launch has two more firm orders on its books. The company will launch the Eutelsat 70B communications satellite in late 2012 and the Intelsat 27 payload in early 2013.

Karlsen said engineers will soon institute evolutionary upgrades on the Zenit 3SL launch vehicle, increasing its lift capacity to geosynchronous transfer orbit up to 6,400 kilograms, or more than 14,100 pounds.

Geosynchronous transfer orbit is the standard drop-off point for launches of communications payloads heading for 22,300-mile-high stations over the equator, where satellites appear to hover over a fixed point on Earth to provide broadcasting services.

Later changes will allow the Zenit 3SL to haul up to 6,700 kilograms, or 14,770 pound, into such an orbit.

6000-> 6400 -> 6700 на ГПО - неслабая оптимизация, это все опыт ДМ-SLБ ?

или модификациции будут такими?

Там скорее замена боинговского обтекателя с мембраной на 81КС от Союза-2.
