'Here in Death Valley, we have a unique ability to help understand other worlds.'

With its rugged terrain and unique landscapes, Death Valley often acts as Mars for NASA scientists testing space-bound equipment.Spectacular craters, a giant valley and dunes illuminated with red and pink hues pepper the landscape. Extreme weather brings icy cold and dangerously hot temperatures. This foreign world is no place for humans., one of the hottest and driest places in North America.

Researchers tested key aspects of the Mars rovers' navigation systems in Death Valley. Here, NASA’s Perseverance rover lands on Mars on Feb. 18, 2021.NASA’s work in Death Valley dates back to the 1970s and the groundbreaking Viking Project, the first U.S. mission to land a spacecraft safely on the surface of Mars."Some of the first pictures that the world ever saw of Mars came from [Viking]," Allen Chen of the NASA Jet Propulsion Laboratory told SFGATE in a phone interview.

Chen led the Mars landings of both the Curiosity and Perseverance rovers and has been part of several visits to Death Valley throughout his 20-year tenure with NASA. "It’s a rite of passage for people who work on Mars to find your way out to Death Valley for some reason," he explained."Whether it’s scientists who work on rocks or whether it’s more on the engineering side or if you’re someone like me who worries about landing things, once you get past those phases, it’s about getting out there and doing hardcore testing to prove to yourself that it will actually work when you land on Mars.

Work it did. Both rovers have been roaming the Martian surface since their landings, beaming back incredible images as they carry out their missions.The national park that’s been used for scenes in"Star Wars" and"The Twilight Zone" is a"living laboratory" of sorts because of its strange and dynamic features, according to Death Valley National Park ranger Matthew Lamar.
