The rainbow-colored map, to be launched in batches over 6 months, covers the huge bulk of the world Mars, exposing lots of minerals discovered on its surface area.
Researchers are about to get a make over at the Red Planet, thanks to a various colored 5.6-gigapixel map. Covering 86% of the surface area of Mars, the map reveals the distribution of dozens of key minerals. By looking at mineral distribution, researchers can much better comprehend Mars watery past and can prioritize which areas need to be studied in more depth.
The very first parts of this map have been released by NASAs Planetary Data System. Over the next six months, more will be launched, completing one of the most thorough studies of the Martian surface ever made. (Read more about these map sectors.).
Covering 86% of the surface area of Mars, the map reveals the circulation of dozens of key minerals. By looking at mineral circulation, researchers can better comprehend Mars watery past and can focus on which regions need to be studied in more depth.
This near-global map was recorded by NASAs Mars Reconnaissance Orbiter using its Compact Reconnaissance Imaging Spectrometer for Mars, or CRISM. The yellow square shows the Nili Fossae area of Mars, which is highlighted in six views in the previous image. NASA has also utilized CRISMs maps to select landing sites for other spacecraft, as with Jezero Crater, where NASAs Perseverance rover is exploring an ancient river delta.
NASAs Mars Reconnaissance Orbiter, or MRO, has been mapping minerals on the Red Planet for 16 years, with its Compact Reconnaissance Imaging Spectrometer for Mars, or CRISM. (MRO launched on August 12, 2005, and reached Mars on March 10, 2006.).

Using detectors that see infrared and visible wavelengths, the CRISM team has actually previously produced high-resolution mineral maps that supply a record of the formation of the Martian crust and where and how it was changed by water. These maps have been essential to assisting researchers understand how lakes, streams, and groundwater shaped the planet billions of years back. NASA has actually likewise utilized CRISMs maps to select landing websites for other spacecraft, similar to Jezero Crater, where NASAs Perseverance rover is exploring an ancient river delta.
The first piece of this new map includes 51,000 images, each of which represents a “strip” 336 miles (540 kilometers) long by 6 miles (10 kilometers) large that was caught as MRO passed overhead. The resolution is lower than CRISM maps made from targeted observations because the data was obtained with the instrument looking directly down, a different imaging technique created to cover much more of the world.
To obtain its information, CRISM used two spectrometers, one of which was created with three cryocoolers to keep temperatures low so that it might more clearly find the longest wavelengths of shown solar infrared light. This will be CRISMs last map covering the instruments full wavelength variety.
One last map will be released within the year, covering noticeable wavelengths and focusing just on iron-bearing minerals; this will have two times the spatial resolution of the most recent map.
” The CRISM investigation has been one of the crown jewels of NASAs MRO objective,” said Richard Zurek, the objectives project scientist at NASAs Jet Propulsion Laboratory in Southern California. “Analyses based on these last maps will offer new insights into the history of Mars for numerous years to come.”.
MRO is led by Jet Propulsion Laboratory (JPL), which is a division of Caltech in Pasadena. CRISM is led by Johns Hopkins Universitys Applied Physics Laboratory.
