NASA’s Mars rover finds rainbow colored ‘mother-of-pearl’ clouds

Mars has a lot of wind and dust demons. But unlike the world, it is not famous for clouds. That’s one reason NASA̵

7;s Curiosity Rover’s collection of Mars clouds images is so amazing.

Scientists noticed clouds starting to form on Mars earlier than expected, so this year they waited to make sure Curiosity was able to capture intangible formations, some of which have very colorful characteristics.

“More than a spectacular exhibit, the image helps scientists understand how clouds form on Mars and why the latest clouds are different,” NASA said in a statement Friday.

Researchers discovered clouds that arrived the fastest appeared at higher altitudes. Mars clouds are generally made of ice, which is what we see on Earth. But these high-flying clouds could be made from dry ice, freezing carbon dioxide. The idea is still being reviewed.

Curiosity has captured the clouds this year. You can see the clown moving in a GIF that NASA has put together. Some are examples of clouds. “Shine at night” made of ice in the water. “When viewed after sunset, their ice crystals capture fading light, making them appear to glow relative to the darkened sky,” NASA said.

Lightless clouds are made of ice. Curiosity destroyed them on March 31, 2021.

Noctilucent clouds also occur on Earth. Researchers watched them in our upper atmosphere last year. In the Arctic they sometimes wander and can be seen as far south as possible.

Curiosity’s Mars Clouds scrapbook also includes color images showing beautiful “mother-of-pearl” clouds sparkling with rainbow colors.

“If you see a cloud with a glittering pastel color scheme, it’s because the cloud particles are almost the same size,” said Mark Lemmon, an atmospheric scientist at the Institute of Space Science in Colorado. “It usually happens after clouds have formed and grew at the same rate.”

Lemmon said that these intangible clouds It is as if Mars decided he didn’t want to be stereotyped. “Red Planet” longer, while the pinks and blues and greens of the clouds demonstrate its color palette.
