NASA finds water ice just below the surface of Mars – Engadget, Engadget




Researchers created the map of the Martian surface which shows where water ice is believed to be located. In some places, the ice is as little as 2.5 centimeters below the surface, making it easily accessible to future visitors. Cool colors represent ice closer to the surface, while warm colors are ice deeper down.

“You” wouldn’t need a backhoe to dig up this ice. You could use a shovel, “the paper’s lead author, Sylvain Piqueux of NASA’s Jet Propulsion Laboratory, said in ablog post. “We’re continuing to collect data on buried ice on Mars, zeroing in on the best places for astronauts to land.”

Locating ice is important to enable manned missions to the planet, and could help identify sites for projects likeSpaceX’s planned Mars base. Water is heavy to transport aboard rockets, so finding it on Mars will help humans to survive there. However, because the planet has such a thin atmosphere, most water on the surface evaporates quickly.

Scientists realized that lookingbelow the Martian surfaceis the best hope of finding accessible water ice, and that there may even be liquid waterbeneath the polar ice caps. With this new map, researchers have a blueprint for where to start planning missions and eventually sending astronauts to Mars.
