In late August 2008, science writer Richard C. Lewis traveled with Brown planetary geologists to arctic Iceland, where the researchers tested remote-sensing equipment that was used to sample and evaluate the surface of Mars. Lewis sent dispatches to Today at Brown relating each day’s
activities. He also took photographs, which you are invited to view here. The geologists who made the trip were Professor of Geological Sciences Jack
Mustard, Assistant Professor of Geological Sciences Michael Wyatt, and
graduate students Bethany Ehlmann and Ulyana Horodyskyj.

Iceland: Report from the field
The team will analyze the samples it collected when the team and the samples are all back on campus, but the team pronounced the trip a success. They had reached the areas they had wanted and collected the samples they had sought.
Iceland: Report from the field
The geologists explore a mosaic of blackened dunes, jagged cracks in the ground, and giant smoking geothermal vents — some of it the result of “oozy” lava.
Iceland: Report from the field
The quest for Martian conditions leads Brown geologists into what Icelanders call the Mouth of Hell: wind-whipped grit and pebbles, slick orange mud, and the stench of rotten eggs.
Iceland: Report from the field
The researchers explore a neovolcanic zone that is just right — old enough to be altered like the Martian surface, but young enough not to be “contaminated” by vegetation.
Iceland: Report from the field
The team sets out for the area around Askja volcano — bleak, devoid of greenery, but full of caldera, sand dunes and tuff cones. Just the kind of place a geologist would love.
Iceland: Report from the field
Science writer Richard C. Lewis is traveling with Brown planetary geologists in arctic Iceland. He accompanied two researchers on their quest to find a mineral that has implications for Martian life.
Comparative Planetology: Iceland
Iceland, an island nation hugging the Arctic Circle, may share many similarities with ancient Mars. It’s a perfect place to research remote-sensing techniques. Brown science writer Richard C. Lewis is traveling with
a team of Brown researchers and will file reports and photographs from the field.
Comparative Planetology: Iceland
Four Brown geologists are at work in Iceland, conducting research at sites where the topography, minerals and chemical composition of the surface have some similarities to Mars.
