The effect is exposed to darker material under the character of the reddish dust of the planet, according to HiRISE The camera website that released the image.
Veronica Bray, a member of the HiRISE team and scientist at the University of Arizona, said the blue area could indicate "water ice."
"It has not yet been confirmed, but usually, when the HiRISE image of a new effect shows a blue spot, sometimes the ice water," Bray said in a CNN statement.
However, it may not exist
However, Leslie Tamppari, a scientific project for Mars Reconnaissance Orbiter, told CNN that the blue color could be nothing.
"I do not know we should read anything here," Tamppari said. "They underwent these images. All false colors, not true colors … (because) we have no wavelength range."
The crater, measuring 16 meters wide, is estimated to be formed between September 2016 and February 2019. It is located south of the Valles Marineris canyon system.
Scientists have discovered hundreds of bamboo
Scientists have identified more than 500 craters of impact on the planet, Tamppari said. By studying these craters, they will learn about the impact of the crawling process, the statistics of tiny rocks and the frequency of effects.
"We are surprised at how dynamic Mars," Tamppari says. "We see an active crake continuously."
The Mars Reconnaissance Orbiter of the space agency captured the image on April 17. It was released to the public earlier this month. Mars Reconnaissance Orbiter left for Red Planet in 2005 and studied it since March 2006.
