Not one, but two spacecraft mission concepts co-developed by Martha Gilmore, George I. Seney Professor of Geology and professor of earth and environmental sciences, received second-round backing from NASA’s Discovery Program on Feb. 13. Both concepts—which were awarded $3 million each—would assess whether Venus was ever a habitable planet by examining its landscape, rocks, and atmosphere.
NASA’s Discovery Program, now in its ninth year, funds investigations to develop concept studies for new missions. Although they’re not official missions yet, the selections focus on compelling targets and science that are not covered by NASA’s active missions or recent selections. Gilmore’s projects were among four selected.
“Venus is the key to understanding how Earth-size planets evolve. Like Earth, we predict Venus had an ocean that may have lasted for billions of years. Like Earth, Venus may be volcanically and tectonically active today. These missions will target the modern and ancient history of Venus, as recorded in the rocks and the atmosphere. The oldest rocks on Venus are my speciality, and I would very much like to know what environment they record.” Gilmore said.
