You can track the real time progress of MSL and Curiosity at NASA's "Eyes on the Solar System" web site - an interactive web site that lets you track exactly where the Mars Science Laboratory is and then lets you speed up time through a simulated landing - or go backwards in time as well. In addition, you can click on "Explore the Universe" to explore planets as well as riding along (past and future) on some deep space exploration missions (click on Destination"). There are tutorial videos to help with its use (showcased at Planetfest 2012 Saturday): http://eyes.nasa.gov/ Bob and Jann Koepke
