NASA has released new images of clouds over Mars, which were captured by the Curiosity rover in March 2021.
The photographs, published on May 28, were released by the NASA Jet Propulsion Laboratory which explained that “cloudy days are rare in the thin, dry atmosphere of Mars.”
“Clouds are typically found at the planet’s equator in the coldest time of year, when Mars is the farthest from the Sun in its oval-shaped orbit. But one full Martian year ago – two Earth years – scientists noticed clouds forming over NASA’s Curiosity rover earlier than expected,” the lab said in a statement.
According to NASA, the “early clouds” were photographed this year, revealing that they were at “higher altitudes than is typical.” The high altitude means they are “likely” made of frozen carbon dioxide, or dry ice, which results in them being seen to shine at sunset, Credit: NASA/JPL-Caltech/MSSS via Storyful
