The MESSENGER press conference today covered one Mercurian year in orbit and featured woman-in-planetary-science Brett Denevi speaking about new surface features revealed in high-resolution images – clusters of rimless pits.
“The etched appearance of these landforms is unlike anything we’ve seen before on Mercury or the Moon,” says Brett Denevi, a staff scientist at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., and a member of the MESSENGER imaging team. “We are still debating their origin, but they appear to have a relatively young age and may suggest a more abundant than expected volatile component in Mercury’s crust.”
