Brink: New Life on Mars?
With the detection of methane gas in the Martian atmosphere, NASA scientists are working to determine if the emissions are due to biological or geological processes. The program looks back at the history of Mars exploration and examines how the discovery of methane will influence future exploration of the Red Planet. Host Josh Zepps interviews geologists, biologists, and astronauts who consider the type of organisms that may inhabit Mars and the possibilities of a manned mission to the neighboring planet. High-tech instruments aboard the Mars Reconnaissance Orbiter and the Mars Science Laboratory promise to provide scientists with valuable information about the climate, weather, and surface of Mars.
