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  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.
