The Mesquite Flats Sand Dunes: Exploring a Desert With Soil Like Mars
If you ever wanted to step into a Mars-like environment, then you need to head out to the Mesquite Flats sand dunes. Located in Death Valley National Park in California, the Mesquite Flats is one of the most characterized and extraordinary places to visit within the United States. This surreal setting is known for its immense dunes with sand that is often likened to the Mars soil. In this article, we will explore the Mesquite Flats, its otherworldly characteristics, and how it is similar to the soil found on Mars.
The Mesquite Flats is an area of the Stovepipe Wells in Death Valley National Park that consists of extremely dry sand dunes. Spanning two square miles and dotted with Mesquite Trees around the edges, it’s the most detailed and accessible example of sand dunes in the area. In addition, the Mesquite Flats is stargazers’ paradise – the night sky completely dark, providing unparalleled views of the Milky Way.
The uniqueness of the Mesquite Flats is also attributed to its extraordinary soil. With every step, the sand shifts and falls through one’s fingers – its texture and color remarkably similar to the Martian soil. This is what made the Mesquite Flats one of the go-to destinations to simulate the environmental conditions on Mars to test out potential spacesuits, materials, and robots before they launch.
What Makes the Soil at Mesquite Flats Similar to Mars?
For over a decade, scientists have discovered that the soil on Mars is much more than just a desert-like planet. It is extremely unique, with little soil organic matter, lots of free iron particles, and abnormally high levels of silica. These features are also some features of the sand at the Mesquite Flats.
The sand of the Mesquite Flats desert consists of iron oxide and also has an iron-rich dust layer – similar to the soil on Mars. The presence of iron in the soil makes it reddish in color, like most of the Martian surface. The Mesquite Flats also contain a high amount of silica, which is similar to the elemental makeup of the soil on Mars. In addition, the sand is so fine it decomposes quickly in the atmosphere, causing the increasing dust storms on Mars.
Benefits of Testing at the Mesquite Flats
The similarities between the two environmental conditions make the Mesquite Flats a great platform for research and product testing. Unique conditions, such as the high temperatures, fine sand, and high levels of dust, make it a great place to test out new spacesuits, materials, and other technologies. In the past decade, NASA, r the US Army, and numerous other organizations have tested their products in the desert of Mesquite Flats.
NASA Astronauts suit up to take a simulated spacewalk at the Mesquite Flats in Death Valley National Park
In 2015, NASA Astronauts volunteered to suit up to take a simulation of a spacewalk as part of the Extreme Environments mission operations. With the help of portable air- and water-reclamation equipment, the Astronauts replicated the air and environment on Mars. The team also used a full-scale prototype of the Space Exploration Vehicle (SHEV) to test how the terrain on Mars would challenge the vehicle’s performance.
Testing on new spacesuits was the other aspect of the operation. The Astronauts tested their abilities while wearing the prototype Pro-ximity elasticated intra-vehicular activity (IVA) suit. The IVA suit not only protects astronauts from hazardous materials but also increases their abilities, allowing them to get close to the harsh terrain of Mars without risking personal injury or damage.
NASA Mars Rover Testing at the Mesquite Flats
Apart from testing out the products on Astronauts, the Mesquite Flats is also used to test out NASA’s Mars Rover. Mars Rovers are mobile robots with the mission to explore the Red Planet. NASA uses the terrain of the Mesquite Flats to test out the driving capabilities of the Mars Rover and its robotic arm.
The Curiosity Rover was tested in the Mesquite Flats desert in California
The field test for the Curiosity Rover consisted of tests to make sure the Rover could cover rocky, sandy, and dusty terrain. Its capabilities to move over the same surfaces and edges that are present on Mars were also tested and optimized. The Curiosity Rover was also instructed to conduct multiple tests with its robotic arm and unmanned aerial drone (UAV).
The Mesquite Flats desert in Death Valley National Park is one of the most extraordinary spots in California. It is known for its immense Martian dunes and is a go-to place to simulate and test the environment of Mars. The soil of the Mesquite Flats is remarkably similar to the Martian soil, with its reddish color, iron-rich dust layer, and high amount of silica. The desert has been used by numerous organizations and NASA to test out their products and technologies that are designed to explore our nearest planet. From testing out Astronauts’ spacesuits and the Mars Rover, to testing out the robotic arm and UAV, the Mesquite Flats offers the perfect platform for testing in an environment similar to that of Mars.
