# Swimming in Martian Lakes: Curiosity at Gale Crater

As primitive life was becoming established on Earth, Gale Crater on Mars was a shallow lake filled with drinkable water and brimming with all of the chemical ingredients necessary for life to form. NASA's Scott Guzewich discusses the five-year effort to explore the remnants of this lake with the Curiosity rover. For the first time in the history of space exploration, we are directly studying an environment that was once habitable for life as we know it. The story of Gale Crater tells us how Mars has changed and whether life may be common in the universe.
