Although it looks like a beautiful snow on the Red Planet, Crater Korolev would be more suitable for skating on the board than for the construction of snow.
The European Space Agency announced on Thursday an image captured by the Mars Express mission, featuring a crater filled with water ice.
But the crater is not just frozen because of the winter season. Krut Korolev is filled with ice that is about 1800 meters thick throughout the year.
The crater, which is almost 80.6 kilometers wide, is located south of the northern polar gate, known as Olimpia Undae, in the northern lowlands.
The deep base of the bottom of the crater, about 1.9 miles below the perimeter, contains ice and acts as a cold trap. The air moving over the ice cools and sinks, creating a layer of cold air over the ice. This allowed the ice to remain melted.
The crater was named after Sergei Korolev, the chief rocket engineer and designer of the ship, known as the father of Soviet space technology.
Korolev worked on the Sputnik program, the Vostok program, which in 1961 carried the first man into space and missiles that were precursors for the Soyuz launcher.
The image itself is a complex picture of the crater taken from the camera of the high resolution Mars Express.
Mission of the European Mission of the European Space Agency Mars Ekpress celebrates 15 years after being launched in June 2003, and on December 25, 2003 it entered Marsovska orbit.
InSight sets its first instrument
The work never stops NASA's InSight mission. From landing on March 26, the lender photographed and explored the environment.
And on Wednesday, he placed his first instrument on the surface, a seismometer – for the first time a seismometer was on the surface of another planet.
The robot arm of the lander can reach about 1.6 meters, so the seismometer is placed at that distance in front of the landing.
"The seismometer distribution is as important as the landing of InSight on Mars," said InSight chief researcher Bruce Banerdt.
"Seismometer is an instrument with the highest priority on InSight: we need to complete about three quarters of our scientific goals."

It is known as SEIS, short for Seismic Experiment for Internal Structure.
"The schedule of InSight's activities on Mars has gone better than we hope," said Tom Hoffman, project manager at InSight.
"Getting a seismometer safely on the field is a great Christmas present."
A seismometer will help scientists understand what is happening below the surface of Mars, discover "masquerades" and analyze seismic waves.
"The seismometer in the field is like keeping your phone up to your ear," said Philippe Lognonne, SEIS's chief researcher at de Phisikue du Globe de Paris and Paris Diderot Universiti.
"We are delighted that we are now in the best position to listen to all seismic waves beneath the surface of Mars and from the depths of the interior."
New data will begin to arrive on Earth when a seismometer is set to level.
The Rotation and Internal Structure Experiment, or RISE, is active on a spaceship, using the vibration tracker of the northern half of Martia as a solar tow on its orbit. This will provide more information about the core of the planet.
The heat probe will be pushed back to the surface by the end of January.
Mission experts are ready for the data that SEIS will send their way.
"We look forward to getting champagne when we start getting data from InSight's earth seismometer," Banerdt added.
"I have a ready bottle for this occasion."
