By looking at high-resolution images captured by the Mars Reconnaissance Orbiter, scientists are able to see gullies, which are argued to be geologically recent. Because they are most likely formed by water, it is believed that they can answer the question of whether or not there is still “active” water on Mars.
As a summer Wesleyan McNair scholar, astronomy major Lavontria Aaron ’14 used a hyperspectral instrument to determine if the gullies contained minerals (salts) which would be left behind by water brines.
“By examining the spectrum of the brines, we’ll be able to learn more about Mars’ history and possibly man’s future in pursuit of exploring the red planet,” says Aaron, who worked on the project with her faculty advisor Marty Gilmore, chair and associate professor of earth and environmental sciences.
Aaron and her 13 McNair peers are supported by the Ronald E. McNair Post Baccalaureate Achievement Program, which serves students in their second, third, and fourth college semesters. It provides career-oriented activities,
