"We don't know how long the Dagwood-sandwich structure would exist. This structure represents a stable state, but various factors could mean the moon doesn't reach this stable state," Dr. Christophe Sotin said in a May 1, 2014 statement. Dr. Sotin is of the JPL. Tracing our Moon's changing porosity may ultimately help astronomers to track the trajectory of the invading army of a multitude of lunar impactors, that occurred during the Late Heavy Bombardment, 4 billion years ago. Dr. Soderblom and his team, including Dr. Maria Zuber, who is the E.A. Griswold Professor of Geophysics and MIT's vice president of research, have published their findings in the September 10, 2015 issue of the journal Geophysical Research Letters.
