On Sept. 30, NASA’s Discovery Program selected five planetary mission investigations for study during the next year as a first step in choosing one or two missions for launch as early as 2020. Wesleyan’s Martha Gilmore is on two of the investigation teams.
Gilmore, the George I. Seney Professor of Geology and chair of the Department of Earth and Environmental Sciences, is an expert on terrestrial planets. She studies the morphology and mineralogy of the surfaces of Venus and Mars using data from orbiting and landed spacecraft. She also is on the Executive Committee of NASA’s Venus Exploration Analysis Group which identifies scientific priorities and strategy for exploration of Venus.
Each of the five selected investigations will receive $3 million for one year to strengthen their proposed mission by doing in-depth concept design studies. At the end of the year, it is expected that one or two of the mission concepts will then be selected for flight.
“We’re absolutely ecstatic about this opportunity,” Gilmore said. “Venus is key to understanding how Earth-size planets operate in this solar system and in other solar systems. The driving question is why are Venus and Earth so different? Why is Earth the habitable twin planet? The measurements of Venus’ atmosphere and surface proposed by these missions are necessary to better understand the climate, volcanic activity and the habitability of Earth-size worlds.”
