Take a tour of winter on Mars with NASA on this vacation video
NASA advocates a ‘winter wonderland’ on Mars.
“Desires of a White Christmas” might by no means conjure up the alien landscapes that seem within the chilly corners of the Pink Planet. However the area company is all excited. Its many missions over the previous few a long time have revealed icy oddities Marsand likewise how a lot Mars resembles Earth at instances.
As NASA is now one mission deep into it Artemis program, it is vitally essential to learn the way people can develop past our planet. Water ice is a worthwhile discovery for this function. I new video (opens in a brand new tab) from the Jet Propulsion Laboratory (JPL) in California—NASA’s foremost hub for robotic area explorers—reveals what snow, frost, and ice appear like on Mars.

“In the event you go to the proper locations, you will discover water ice similar to what’s on Earth,” JPL Mars scientist Sylvain Pickex says in a Dec. 21 video that NASA launched on YouTube (opens in a brand new tab). If NASA Phoenix Mars lander scraped the Arctic Martian soil in 2008he noticed water ice just under the floor.
“That is the kind of water ice that astronauts may doubtlessly use sooner or later once we go there,” Pickex provides.
Mars additionally has dry ice, a strong type of carbon dioxide (CO2). As a substitute of melting like water ice, CO2 ice sublimates. And when this materials turns from a strong state right into a gasoline, it creates alien landscapes.
“For instance, we see spider-like objects, followers, geysers, Dalmatian spots, fried eggs, all types of distinctive objects which can be actually obscure, however that are lovely and distinctive to Mars,” Pickex says.
Ice crystals additionally fall on Mars like snow on Earth. When Phoenix used Canada’s LIDAR (or gentle detection and ranging) to shoot a laser into the planet’s sky, it found water ice crystals falling from a cloud.
Frost additionally covers some locations on Mars. NASA’s Viking landers took photographs of the frost within the Nineteen Seventies, and extra just lately its Spaceship Odyssey and Mars Reconnaissance Orbiter noticed its CO2 frost.
“CO2 frost [is] what we do not need on earth. The place you could find CO2 ice is extraordinarily chilly, about -190 levels Fahrenheit,” Pickex says.
It is a lot colder than December.”bomb cyclone,” which the U.S. is making ready to face this weekend.
However NASA put winters on these two planets into perspective accompanying assertion (opens in a brand new tab).
“No area on Mars has quite a lot of ft of snow, most of which falls on extraordinarily flat areas,” the assertion mentioned. “As chilly because it will get, do not count on Rocky Mountain-worthy snowdrifts.”
