They are going to launch before Quetzsat 1 which is already there?

I hope I hope I hope that they will resolve the problems with the upperstages before then.

We have resolved problem - the failure was due to a mistake in flight programme.

Media Advisory: ILS Proton to Launch ViaSat-1

October 14, 2011

Payload:
ViaSat-1
SS/L 1300

Separated spacecraft Mass:
6,740 kg

Launch Vehicle:
Proton M/Breeze M
705,000 kg (1,554,000 lb), including payload
58.2 m (191 ft)

Launch Date:
20 October 2011, Baikonur

Launch Time:
00:48 Baikonur
18:48 GMT, 19 October
14:48 EDT, 19 October
11:48 PDT, 19 October

Launch Site:
Baikonur Cosmodrome, Kazakhstan
Launch Pad 39

Launch Customer:
ViaSat Inc., Carlsbad, Ca

Satellite Manufacturer:
Space Systems/Loral, Palo Alto, Ca

Launch Vehicle Manufacturer:
Khrunichev State Research and Production Space Center,
Moscow, Russia

Launch Services Provider:
International Launch Services, Reston, Va

Satellite Use:
ViaSat-1 is the highest throughput satellite ever built. The total capacity is in excess of 140 Gbps, more than all other communication satellites over North America combined. The all Ka-band spot beam ViaSat-1 is designed to transform the quality of satellite broadband service through a new system design that focuses on maximizing total bandwidth throughput. In this way, the cost per bit is reduced to a fraction of that provided by previous generation satellites, significantly changing the economics and performance of satellite communications. The satellite, to be located at 115˚W, will use 72 beams to cover 75% of the Continental United States, as well as the most populated areas of Alaska, Hawaii, and Canada.

Satellite Statistics:
__ All Ka-band satellite
__ Orbital location: 115 degrees west
__ 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 ViaSat-1 satellite on board. The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the ViaSat-1 satellite) into a suborbital 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 geosynchronous transfer orbit.
Separation of the ViaSat-1 satellite is scheduled to occur approximately 9 hours, 12 minutes after liftoff.

Target Orbit at Separation:
Apogee: 35,786 km (22,236 miles)
Perigee: 2,363 km (1,468 miles)
Inclination: 30.4 degrees

Spacecraft Separation:
Approximately 9 hours, 12 minutes after liftoff

ILS Mission Statistics:
__1st Satellite Launch for ViaSat
__19th Space Systems/Loral Satellite Launched on ILS Proton
__4th ILS Proton Launch in 2011
__68th ILS Proton Launch Overall

More Information:
Live webcast at www.ilslaunch.com will begin approximately 20 minutes before liftoff. General mission information and launch status updates are available at the website, and on the ILS Facebook and Twitter page.

More capacity than ALL the satellites over North America? That can't possibly be true--can it?
