What effect has weather had on the Martian surface throughout the planets history?
Dr. Stubbe Hviid will investigate the effect that weather has had on the Martian surface following the planet’s formation approximately 4 billion years ago. In particular, he seeks to address whether liquid water was present on Mars for enough time to have significant influence on the surface evolution. To accomplish this study, Dr. Hviid will characterize the soil mineralogy and the shape of the terrain at the landing sites. Specifically, his team will focus on topics such as iron phases, crystallites, magnetism, suspended atmospheric particles, dust composition, and the scattering of light in the atmosphere. His investigations will utilize the full suite of instruments, ranging from imaging using Pancam and the Microscopic Imager to measurements using APXS and the Mssbauer Spectrometer.

Dr. Ronald Greeley will investigate surface-atmosphere interactions on Mars with a focus on wind-rela
