Saw the MSL video, which was similar to the MER video. It was awesome. Will try to get a copy

From the document posted by djellison above... page 4.

...Approximately 5 minutes before entry interface, two external cruise balance masses are jettisoned to create an offset center of gravity...

...In contrast to the spin stabilized entries of MER and Mars Pathfinder (MPF), MSL utilizes an offset center of mass to create a nominal 18degree angle of attack through peak heating and dynamic pressure, increasing to a 20degree angle of attack just prior to parachute deployment. This angle of attack generates lift which is used to reduce the landing error ellipse size and increase the parachute deploy altitude.

Lots more exciting facts to be found in that document smile.gif
