SUMMARY: A Russian Proton rocket lifted off from the Baikonur Cosmodrome on Wednesday, carrying a Brazilian Amazonas satellite into orbit. The rocket launched at 2232 UTC (6:32 pm EDT), and its Breeze M upper stage placed the satellite into a geosynchronous transfer orbit 9 hours, 11 minutes later. When it reaches its final position of 61-degrees West, it will provide broadcast television services to countries on both sides of the Atlantic Ocean.

I love the UR-500 Proton. People have falsely called the R-7 Sputnik/Soyuz launcher "Proton" for years--even Lou Dobbs. UR-500 is a larger rocket that looks like the Saturn IB and actualy has a bit more thrust.

Outside of the Shuttle and the wonky Delta IV 'heavy' the only rocket we have to match it is the near extinct Titan IV. The Air Force robbed the ABMA of space--and thought they didn't need such vehicles.

Then they stretched Titan II into III and IV which were more expensive.
At its finish--Titan IV puts about the same tonnage in LEO as a stock Saturn IB--which could have carried half again as much had it been kept and modified.
