Payload:
Telstar 14R/Estrela do Sul 2
SS/L 1300
Separated spacecraft mass: ~5,000 kg

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

Launch Date:
21 May 2011, Baikonur

Launch Time:
01:15 Baikonur
19:15 GMT, 20 May
15:15 EDT, 20 May

Launch Site:
Baikonur Cosmodrome, Kazakhstan
Launch Pad 39

Launch Customer:
Telesat, Ontario, Canada

Satellite Manufacturer:
Space Systems/Loral, California, USA

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

Launch Services Provider:
International Launch Services, Virginia, USA

Satellite Use:
Telstar 14R/Estrela do Sul 2 is a commercial communications satellite built by Space Systems/Loral for Telesat. The satellite will utilize 46 high powered Ku-band transponders (58 36-MHz transponder equivalents) over five coverage beams consisting of: Brazil, the Continental United States (including the Gulf of Mexico and northern Caribbean), the Southern Cone of South America, the Andean region (including Central America and southern Caribbean), and the North and Mid-Atlantic Ocean. Following its launch, Telstar 14R/Estrela do Sul 2 will be located at 63 degrees west longitude where it will replace and augment the communications capability currently supplied by Telesat’s Telstar 14/ Estrela do Sul.

Satellite Statistics:
Ku-band capacity
46 high powered Ku-band transponders (58 36-MHz transponder equivalents)
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 Telstar 14R/Estrela do Sul 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 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 geosynchronous transfer orbit. Separation of the satellite is scheduled to occur approximately 9 hours, 13 minutes after liftoff.

Target Orbit at Separation:
Apogee: 35,786 km (22,236 miles)
Perigee: 8,850 km (5,499 miles)
Inclination: 13.8 degrees

Spacecraft Separation:
Approximately 9 hours, 13 minutes after liftoff

ILS Mission Statistics:
7th Telesat Satellite Launched on ILS Proton
17th Space Systems/Loral Satellite Launched on ILS Proton
1st ILS Proton Launch in 2011
65th ILS Proton Launch Overall; 364th Proton mission since 1965

Hope it has better luck than the original Telstar 14!

So there's STS-134, Ariane 5 and this one. Crazy day

Although Proton launches before Ariane, we'll know the Ariane result long before we'll know the Proton result thanks to the latter rocket's nine hour mission. Good luck to both!

What's wrong with the original? I've been using it for years. This post is going over it.
I had wondered why such a young bird was being replaced.

According to http://www.loral.com/inthenews/040113.html

the original Telstar 14 didn't fully deploy its ~~antennas~~ solar arrays, so a replacement is needed.
