Actually, according to Novosti kosmonavtiki forum, yesterday satellite was fueled by oxidizer, and tomorrow he will be fueled by propellants.

Is this mission still planned for injection in a 48 degree orbit, or was this vetoed by Kazakhstan?

http://www.russianspaceweb.com/2009.html

"In the meantime, the DirecTV mission was under pressure to launch before the end of 2009, in order to use an optimized launch azimuth enabling reaching an initial parking orbit with the inclination 48 degrees toward the Equator, agreed with the government of Kazakhstan. It was expected to be the last mission heading to the 48-degree parking orbit, which enabled around 200 kilograms of extra payload delivered to the geostationary transfer orbit. In the wake of the JCSAT-11 failure, which landed debris within 40-50 kilometers of the town of Dzhezkazgan, Kazakhstan prohibited this particular launch path after 2009"

DirecTV-12 satellite has been integrated with Proton
21.12.2009

http://www.khrunichev.ru/main.php?id=1&nid=475

Pre–launch operations for DirecTV-12 launch on a Proton Breeze M launch vehicle continue on schedule. During the last weekend, members of the Khrunichev launch team completed the DirecTV spacecraft general integration with Proton launch vehicle.

During those operations the Space Head Unit (i.e. the DirecTV-12 spacecraft/adapter/the Breeze M upper stage stack encapsulated into the Proton fairing) was integrated to the three stages of the Proton core rocket.

The Proton Breeze M Integrated Launch Vehicle will undergo electrical checkouts throughout the day. The next day the ILV will be made ready for transport to the fuelling station,where the Breeze M low pressure tanks are to be fueled.

Launch Site:                        Baikonur Cosmodrome, Kazakhstan

                                                Launch Pad 39

 

Launch Customer:             DIRECTV, El Segundo, California

 

Satellite Manufacturer:      Boeing Space & Intelligence Systems, El Segundo, California

 

Launch Vehicle                   Khrunichev State Research and Production Space Center,

Manufacturer:                      Moscow

Provider:                               International Launch Services, Reston, Va.

 

 

Satellite Use:                       The DIRECTV 12 next-generation satellite will play an important role in extending DIRECTV’s content leadership position in the pay TV industry.  When it becomes operational in the first half of next year, it will expand DIRECTV’s HD capacity by 50 percent to more than 200 national channels. The powerful 131-transponder payload integrates 32 active and 12 spare TWTAs (Traveling Wave Tube Amplifiers) at Ka-band for national service and 55 active and 15 spare TWTAs for spot beams. The payload is powered by a gallium arsenide solar array that spans more than 48 meters. DIRECTV 12 will receive and transmit programming throughout the United States with two large Ka-band reflectors, each measuring 2.8 meters in diameter and nine other Ka-band reflectors.

 

Satellite Statistics:             — 70 Ka-Band transponders

                                                __Orbital location: 102.8 West longitudes

                                                __Anticipated service life: 15 years

 

Mission Profile:                   The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the DIRECTV 12 satellite on board. The first three stages of the Proton will use a standard ascent profile to place the Ascent Unit (payload fairing, Breeze M upper stage and the DIRECTV12 satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission maneuvers to advance the Orbital Unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geo-transfer orbit.  Separation of the DIRECTV 12 satellite is scheduled to occur approximately 9 hours, 12 minutes after liftoff.

 

Target Orbit                         Apogee: 35,786 km (22,236 miles)

at Separation:                      Perigee:  5,120 km (3,181 miles)
Inclination: 20.7 degrees

 

Spacecraft Separation:     Approximately 9 hours, 10 minutes after liftoff

Not at all, Sixto! Thanks should goes to Roskosmos and Khrunichev. I am only mediocre translator. :)

According to http://coopi.khrunichev.ru/main.php?id=201, the launch time is 00:22:00 UTC.

DirecTV-12 Mission: Proton M Moved to Breeze M Fuelling Station
23.12.2009

http://www.khrunichev.ru/main.php?id=1&nid=476

Early this morning, the Proton Breeze M launch vehicle with the DirecTV-12 spacecraft (encapsulated into fairing and wrapped in its protective shroud) was moved from the Proton integration facility to fueling station located at Area 31, where the launcher will undergo final preparations before being moved to Launch Pad 39 at Area 200. These activities include  loading of low-pressure fuel and oxidizer into the Breeze M upper stage, which will last within two days. Technical crews (from Khrunichev and Chemical Machinery Design Bureau - “KB TKhM”) have already begun the fuelling operations.

Once the propellant components are loaded, the members of Russian State commission will meet at Baikonur to give authorization for the rollout of the Proton LV to launch pad 39.

That's a typo in the article about Area 31.  Should be Area 92.  The Breeze M propellant loading is done right outside the LV integration building in a structure the US personnel call the "car wash."  Anik posted a great picture of it.

Edit to add -  You can see the car wash in the middle picture too, in the background, looking down the length of it.

Yes, you are right. Fueling of high pressure tanks of Briz-M upper stage is performing on area 31. Fueling of his low pressure tanks is carrying out on area 92A (see image from Google Earth below).
