Martha Gilmore, George I. Seney Professor of Geology, professor and chair of earth and environmental sciences, joined legendary astronaut and engineer Buzz Aldrin and Hoppy Price of NASA’s Jet Propulsion Laboratory for a discussion on WNPR about the past, present and future of space exploration. The three were guests on The Colin McEnroe Show on May 25.
Aldrin, who was one of the first two humans to walk on the moon, is the author of a new book, No Dream is Too High: Life Lessons From a Man Who Walked on the Moon.
McEnroe asked Gilmore about our current level of understanding about Mars.
“Our knowledge of Mars has really increased over the last two decades, and that’s because of a sustained series of missions, a flotilla of spacecraft in orbit, roving and on the surface of Mars that have been able to learn upon each other’s discoveries and leverage each other’s assets. We understand now not only that it was habitable on Mars at the same time that life evolved on Earth, but also where it’s habitable. And so the last rover we landed on the surface of the planet has landed in a place where there was mud and there were rivers and there was sustained water over long periods of time. So we understand now a lot about the history of Mars and the history of water on Mars and the environments that exited on Mars at the same time life was evolving on Earth.”
