No, the Ares rocket is what they are working on now - it's not ready yet. It has it's first test flight later this summer. (was originally supposed to be June, now pushed back to late summer). The Ares I and the Ares V are the 2 launch vehicles for the Constellation program, which replaces the Space Shuttle program. They hope to have Ares I ready for human transportation into space by 2015. Then, along with the Ares V, they'll begin long duration space flight missions, long term lunar stays, and eventually on to a manned mission to Mars. (which will be approx and 2.5 year round trip journey due to distance travelled). The Constellation program is already well under way, but there are still many groups trying to pursuade NASA that there are other, more cost effective solutions available, such as using Delta IV H (heavy) in place of the Ares V, and reconfiguring Atlas and other Delta rockets in place of the Ares I.
