Future work

• Determine the sulfate minerals present in
  additional bright soils on Mars.

Future work

• Determine the sulfate minerals present in
  additional bright soils on Mars.
• Determine the sulfates present in the Meridiani
  bedrock

Other Projects

• Continue spectral study of phosphates (proposed)
• Emission spectroscopy of sulfides (funded)
• TES and THEMIS mapping of NE Meridiani Planum and
  other regions (funded proposed)
• Lithologic (periglacial) mapping in the Martian
  northern plains using TES and THEMIS data
  (funded) hydrovolcanic landforms (proposed)
• Continue study of meteorites (funded)
• Spectral analysis of the Brophy Sheridan 1965
  suite of jarosites and alunites
