The Rover “curiosity” on Mars made a very fascinating image. The photo published on the website of the US Room Trip Authority shows an iridescent (dazzling in Rainbow Colors, Note) cloud, whose shape is reminiscent of a pen shortly after sunset.
The photo (see above) was taken on January 27, 2023 in the course of the Twilight Cloud Survey Research Mission, in which – with the help of “Curiosity” – clouds at Mars in Schemering. The colors of iridescent clouds reveal something about the particle size in the clouds and how they develop over time.
Dawn Clouds were spotted for the first time in 1997 as part of the NASA mission “Pathfinder” on Mars; She only discovered “Curiosity” in 2019 when it took the first photos of glittering clouds – a phenomenon that appeared in the early autumn in the southern hemisphere of the red planet.
A big mystery is why the twilight clouds of carbon dioxide ice cream were not seen in other places on Mars. “Curiosity, which landed in 2012, is on Mount Sharp in the Gale Crater, on the right south of the Marse Equator. “Pathfinder” landed in Ares Vallis, north of the equator.
Do gravitational waves form these clouds?
Mark Lemmon, an expert in the field of atmospheric research at the Space Science Institute in Boulder (Colorado), and others suspect that certain regions of Mars could be susceptible to form such clouds. A possible source can be gravitational waves that can cool down the atmosphere, he said.
“It was not expected that carbon dioxide (CO₂) was condensed here in ice. So far something has cooled in the atmosphere that this can happen. However, the gravity waves on Mars have not yet been fully investigated, and we are therefore not entirely certain, which means that twilight clouds form in one place and not on another, ”says Lemmon.
Rover has been on Mars since 2012
“Curiosity” ended up on Mars in August 2012 and is looking for traces of the previous life. With almost 900 kilograms and three by 2.7 meters, he was the largest self -driven research robot that was sent to the red planet to the robbers “perseverance” landing.
