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.
