Thank you, David.

You can also read the Dawn Journals at their source, which is http://dawn.jpl.nasa.gov/mission/journal.asp. For reasons I don't know, readers at the Dawn website have a slight tendency to post more illuminating questions (and occasionally there are even answers to go with them).

Subject: [FPSPACE] Dawn spacecraft long distance repair

The Dawn spacecraft is on its way to the Dwarf Planet Ceres, after its successful encounter with the Asteroid Vesta.  A cosmic ray collision with the spacecraft's memory and associated software, caused a series of major problems.  The Planetary Society's Dawn Journal provides an insightful description of the problem that developed and how the teams went about finding an eventual solution to get the spacecraft back in schedule for its encounter with Ceres on March 6.
