NASA's oldest spacecraft operating on Mars captured a stunning image of blue sand dunes. And the agency issued a statement, last Thursday, entitled Blue dunes on the Red Planet, which shows these sand dunes surrounding the northern polar cover of Mars, which were formed by the action of the winds. The image covers an area 30 km wide, but in fact, the entire area covers an area equivalent to the size of the US state of Texas.
The composite image collects images taken by the spacecraft, from December 2002 to November 2004, by the Thermal Emission Imaging Camera (THEMIS) installed onboard the orbiter Odyssey, which NASA said is the oldest operating spacecraft on the red planet.
In addition to the blue dunes, yellow and orange areas also surround the area, and the colors reflect the temperature of the region.
And NASA explained in another publication that measuring temperatures with a camera (THEMIS) allows scientists to know the nature of materials in areas such as rocks, sand, or dust, which can "fill the gaps about information about Mars.
The Ingenuity helicopter, which was launched on the surface of Mars, took its first color photo on April 3. The image shows the ground of the Jezero crater and parts of the two wheels of the "Perseverance" vehicle that the helicopter was on board. And the agency NASA published a picture showing sand dunes in a crater with a diameter of 5 kilometers, located within the high latitudes of Mars.
