DESCRIPTION:The small obliquity of Mercury and the Moon causes topographic 
 depressions found near their poles to cast highly persistent shadows. In t
 he absence of an atmosphere\, these permanently shadowed regions (PSRs) ma
 y cold-trap and preserve volatile species\, such as water\, for billions o
 f years. While on Mercury\, observations in radar\, surface reflectance\, 
 and visible imagery detected pure\, glacier-like ice deposits inside most 
 of its north-pole permanent shadows\, similar observations conducted on th
 e Moon have found its polar cold-trapped ice is surficial and patchy\, and
  likely mixed-in with the regolith. In the talk\, we will review the accum
 ulation and destruction of ice within cold-traps and attempt to resolve th
 e difference between the reservoirs of ice on Mercury and the Moon.\n\nDr.
  Lior Rubanenko is a visiting professor in the Department of Earth and Pla
 netary Sciences at Stanford University. He also leads the Laboratory for M
 achine-Assisted Planetary Science (i.e.\, MAPS) as an Assistant Professor 
 in the Faculty of Civil and Environmental Engineering at Technion in Israe
