You can find out a lot of information about the GRACE satellite on the GRACE website, but most information using the GRACE data appears in peer-reviewed publications. For example, Chen et al. 2007 discuss the recent change in the Patagonian Ice Sheet, and in the Antarctic Ice Sheet.
Skeptical Science also discuss the use of GRACE data in measuring ice mass loss from these ice sheets. NASA also summarises some recently published work.
