So when the shuttle is gone we have no way of getting heavy objects into orbit like pieces of the ISS? We have relegated ourselves to simple manned missions just for the sake of going up there and launching satellites?
Ares I has greater payload capacity than the Shuttle. Ares I can put 55,000 lbs in low earth orbit, the Shuttle can lift 53,000 lbs.
The Space Shuttle is not a heavy lift vehicle, and the designers never intended for it to be used to build the space station. It was meant to compliment the Saturn V (which could carry ~250,000 lbs to LEO). The Shuttle would ferry crews and supplies and the Saturn V would have carried up space station components. We went Shuttle only because we thought it would be cheaper, but it ended up being far more expensive.
With the Constellation program NASA is finally getting back to their post-Apollo plans. Ares I will initially be used for ISS resupply. Later on the Ares I and Ares V will be used together for missions to the Moon/Mars/asteroids/etc, orbital construction, whatever.
