European Ariane 5 launcher delivers satellites to orbit

A massive European rocket lifted off from the edge of the Amazon Forest on Wednesday to deliver a pair of commercial broadcast satellites for DirecTV and SKY Mexico.

The direct-to-home telecommunications satellites, DirecTV 15 and Sky Mexico 1, were successfully placed into special transfer orbits. The two spacecraft will be maneuvered over the next week into its proper orbit.

"DIRECTV 15 will provide additional digital television entertainment services for more than 20 million DIRECTV customers in the United States," Astrid Emerit, spokesperson for Airbus Defense and Space said.

SKYM-1 will add a larger coverage map for Mexico's pay-TV provider, Sky, a sister company to DirecTV. The spacecraft will expand HD broadcast channels for customers in Mexico, the Caribbean and Central America.

The Ariane 5 heavy lift launcher thundered into the cloudy skies from its launch site in Kourou, French Guiana at 5:16:07 p.m. EDT (6:16 p.m. local time), and seconds later began to dart out over the Atlantic waters.

Two minutes later, the rocket's twin boosters separated on time, meanwhile Ariane's core Vulcain engine continued to push the rocket higher.

DirecTV 15, which rode to orbit in the top of the two satellite stack, was deployed at 5:43:54 pm high over eastern coast of central Africa. Ten minutes later, SKYM-1 separated from the Ariane's upper stage -- both satellites beginning an expected 15-year life on orbit.

“DIRECTV 15 is not just the 100th telecommunications satellite we have built for geostationary orbit it is also the most powerful television broadcasting satellite ever built in Europe, the most powerful used in the USA and our 8th satellite to use electric propulsion for station-keeping,” François Auque, Head of Space Systems, stated on Monday. “This launch once more highlights the expertise and competitiveness of Airbus Defence and Space as the prime contractor for both the DIRECTV 15 satellite and the Ariane 5 launcher.”

Russian Proton rocket launches DirecTV satellite

A new satellite which will increase the amount of high definition channels DirecTV offers arrived in orbit tonight, and will spend the next several hours moving into a permanent position to service the United States this spring.

An International Launch Services Proton-M rocket lifted-off on time at 7:22 pm EST tonight (0022 GMT Tuesday morning) from a chilly pad 39 at the Baikonur Cosmodrome and into an overcast sky.

The silver 191-foot tall Proton launched into the cold night sky on the final space shot of 2009, and flew eastward out of Kazakhstan and over Mongolia. Two minutes into the flight, the first stage separated from the upper stage.

Spacecraft separation is planned for 4:32 am EST (3:32 pm Baikonur time) on Tuesday.

The seventh ILS Proton launch of the year carried the Boeing-built DirecTV 12 will provide expanded high definition channels for the United States, including Alaska and Hawaii.

The satellite will use two huge Ka-band refelctors -- each measuring nearly 3 meters in diameter -- for the reception and transmission of over 200 cable channels.

Since 1994, Boeing has built 11 satellites for DirecTV.

Proton-M prepares for Monday night launch

On a cold, frosty Christmas morning at the Yuzhny Space Center in Kazakhstan, a Russian Proton-M rocket was transfered to launch pad 39 in preparation for it's night launch on the morning of December 29th (local time).

The snow covered space center was a beautiful touch to a desert region as the Proton was moved by railway. Thank-you to S.Sergeev at Yuzhny for the great images and read our story below)


SpaceLaunchNews.com will carry the prelaunch through ascent LIVE beginning at 7PM EST on Monday evening (0:00 GMT on Tuesday morning).

Russian Proton to Launch DirecTV Satellite Monday

A Russian rocket will deliver to orbit a telecommunications satellite for the Americas next week as the final earth launch of the year.

A new DirecTV satellite will support broader high definition broadcasts to the United States, and increase the amount of HD channels DirecTV carries. Built by Boeing Space, the spacecraft will orbit in geostationary orbit, and will support an additional 200-plus HD channels for the broadcast company.

Liftoff of the Proton M rocket (UR-500) with the DirecTV-12 satellite is planned for December 28th at 7:22 pm EST (0022 GMT Dec. 29) from pad 39 at the Baikonur Cosmodrome.

The 1.55 million pound Proton M's launch profile will see the rocket fly eastward over Kazakhstan, neighboring Mongolia and eastern China before sailing over the Korean peninsula and southern Japan. It's orbital inclination will then carry it over the southern Pacific Ocean and then up toward South America.

The Proton's first stage -- which supports six liquid fueled RD-276 engines and a core engine -- will burn from launch until just prior to stage separation at T+2 minutes. The second stage will then burn three RD-0210 engines for the next 206 seconds of the flight. The rocket's third stage will next take over to carry the satellite into low earth orbit.

A series of five burns will then raise the craft's orbit ever higher to it's geo-transfer orbit.

Spacecraft separation from it's kick motor is scheduled to occur nine hours, ten minutes post-launch over southern Somalia, Africa, in an initial orbit of 3,181 x 22,236 miles.

Designed to operate for 15 years, the DirecTV satellite will become operational by March and operate over the equator at a planned position of 102.8 west longitude.

The 131-transponder DirecTV-12 spacecraft was mated to the Proton's adapter on December 13. A day later, the adapter was then mated to the rocket's Breeze-M upper stage, according to International Launch Services.

Monday's launch will be the seventh ILS Proton launch of 2009, and only the 56th Proton launch for ILS overall.
