NASA has decided to use the Atlas V, with 4 strap-on solid rocket boosters to launch MSL. This is the same rocket that launched MRO (no solids) and New Horizons (5 solids).
Cost: $194.7 million, less than half the price of the Titan IV which would have been needed a few years ago. Rocky Mountain News article NASA press release |

Thrusts I gave are vacuum thrusts, just for comparison. Look on Mark Ward's page for more details about an engine.
The big picture is that Russia and America still offer launch vehicles that are competative with each other. The Russian and American space industry are also somewhat in bed with each other now -- Lockheed Martin jointly operates the Proton, Pratt & Whitney works with EnergoMash, etc. Energiya is the only super-heavy class rocket, but it hasn't actually flown very many times. Overall, I'd have to say the Americans have the more modern technology, and their space industry is big enough to be developing multiple rockets from multiple companies. But NASA learns from the Russians too, you can see that in the Delta IV's engine, which has a lot of Russian features. One intersting decision the Russians made was to design their Energiya booster and their shuttle to be independant modules. The Space Shuttle cannot launch without the 99-ton orbiter and its main engines, in addition to its actual payload. If you consider the total mass put into orbit, it is by far the most powerful LV. I'm adding some info on the largest Chinese rocket to my earlier post with all the data. |
