NASA's orbiter produced a 5.6 gigapixel spectroscopic map of Mars

The new rainbow map, released as a series over six months by NASA, with spectroscopic coverage of almost the entire planet Mars, shows dozens of minerals on its surface. It shows.

Scientists are on the verge of getting a new look at the Red Planet thanks to a colorful 5.6-gigapixel map. Covering 86% of the surface of Mars, this map shows the distribution of dozens of key minerals. By looking at the distribution of minerals, researchers can better understand Mars' watery past and also prioritize which areas need further study.

The first part of this map was published by NASA's Planetary Data System. Over the next six months, more will be released, completing one of the most comprehensive surveys of the Martian surface yet.

    NASA's "Mars Reconnaissance Orbiter" or "MRO" has been mapping the red planet's minerals with the "Comprehensive Reconnaissance Imaging Spectrometer" (CRISM) for 16 years. This orbiter was launched on August 12, 2005 (21 August 2005) and reached Mars on March 10, 2006 (March 19, 2006). They have produced a high-resolution mineral that shows the conditions under which Mars' crust formed and where and how it was changed by water.

    These maps help scientists understand how the planet's lakes, rivers and groundwater formed over billions They were very important last year. NASA has also used Chrism maps to select landing sites for other spacecraft. Including the "Jezero" crater, which was chosen for the landing and exploration of the "Perseverance" rover.

    The first piece of this new map consists of 51,000 images, each representing a strip 540 km long and 10 km wide, and as it passes The Mars Reconnaissance orbiter was taken from above the area. This image is lower in resolution than CRISM maps made from targeted observations because these images were obtained with the instrument looking straight down, a different imaging strategy designed to cover more parts of the planet.

    CRISM, however, To record his data, he used two spectrometers, one of which was designed with three coolers to keep it cool enough to detect the longest wavelengths of reflected solar infrared light more clearly.

    The last of these sequentially used coolers completed their life cycle in 2017, and so the instrument's capabilities to observe visible wavelengths were limited. This will thus be the last CRISM map to cover the full wavelength range of the scientific instrument. The instrument is now in standby mode and may record data a few more times in the coming months before shutting down.

    A final map will be released later in the year, covering visible wavelengths. and focuses only on iron-bearing minerals. This spatial resolution will be twice that of the last map. "Richard Zurek" (Richard Zurek), project scientist of this mission from NASA's Jet Propulsion Laboratory (JPL) said: "Chrism research has been one of the crown jewels of NASA's Mars Reconnaissance orbiter mission. Analyzes based on these final maps will provide new insights into the history of Mars for years to come.

    The Mars Reconnaissance orbiter is managed by the Jet Propulsion Laboratory under the supervision of the California Institute of Technology, and the CRISM scientific instrument is managed by Johns Hopkins University Applied Physics Laboratory.
