SUMMARY:Using the Visible Spectral Reflectance Properties to Probe Aqueous 
 Alteration in the Solar System
DESCRIPTION:Using the Visible Spectral Reflectance Properties to Probe Aque
 ous Alteration in the Solar System\nDr. Faith Vilas\n\nDuring the past 50 
 years, we have witnessed humankind’s first good, detailed look at th
 e planets in our known Solar System.  All of these advances built upo
 n Earth-based telescopic observations.  We predict surface conditions
  on other Solar System bodies before spacecraft reach them for in situ stu
 dy.  The dominant type of asteroid identified telescopically in the m
 ain asteroid belt is classed as a C-complex asteroid, likely the origin of
  many of the primitive carbonaceous chondrite meteorites.In the visible sp
 ectral region, one prominent, identifying spectral feature indicating the 
 presence of Fe2+ → Fe3+ in clay minerals is located near 0.7 µm
  in over half of the C-complex asteroids.  Using its spectral presenc
 e, we can constrain the presence and thermal history of these objects in t
 he Solar System.  I will describe the feature, and the implications o
 f the evidence of its presence.  As an illustration, I will then show
  how we can use the presence of this feature to probe Solar System develop
 mental history through examining the spectra of the jovian outer irregular
  satellites.\n
