James Webb Telescope’s image of Mars after Jupiter in our solar system. Did you see anything new? No, there is nothing new, we already know everything that has been said. Carbon dioxide, water, clouds, craters, atmospheric composition, and temperature distribution are all that the Lander, Rover, and Orbiter on the Red Planet have already told us, so what is the use of James Webb?
James Webb visited Mars on September 5 and viewed the sunward side of Mars with his NIRCam camera and imaged it using 2 frequencies of infrared (2.1 and 4.3 micrometers). Because the sunlight is reflected from Mars and coming to the James Web and the James Web is not designed for so much light, the light coming from Mars was given to the camera for a very short exposure time. Depleted by heat which is called Detector Saturation.

A Brief Overview of James Webb Images
Now let’s take a look at this picture briefly, then let me tell you about the superiority of James Webb’s first pictures. The first image (the MOLA instrument) is an earlier image taken by the Mars Orbiter Laser Altimeter that was carried on the Mars Global Surveyor orbiter (1997 to 2006). Let’s look at James Webb’s photo as a reference to this photo. You see 3 areas.
Hellas Basin, Syrtis Major, and Huygens Crater. These three can be compared in the conceptions of James Webb and MOLA. In the 2.1 micrometer filter (Top Right), James Webb’s image is the same as a normal camera image. It includes the black mark of Syrtis Major’s lava and the rim of Huygens Crater. In the 4.3 micrometer filter (right bottom) there is a lot of heat coming off the surface of Mars, but a different thing is that the Hellas Basin looks a little darker. Why? Because it is a crater and the pressure of the Martian atmosphere above it is high, the heat escape from the Martian atmosphere is a little less. The second image shows spectroscopy of compounds in the Martian atmosphere using the NIRSpec camera.

What Priority Will James Webb Have?
All the missions that have been to Mars have been able to see a very small area, for example the Curiosity and Perseverance rovers have so far traveled only 28 and 12 km, which does not explore the maximum area of Mars. The Mars Orbiter (LRO) can also cover a very small area at a time.
James Webb would have the privilege of being able to see a great part of Mars in a short time, its land, its snow clouds, its storms, its rocks, its plains, the cause of day and night in its atmosphere. Variations from, and changes in the seasons, how much the sun’s heat affects which regions of Mars, James will be able to do with a picture. In fact, these images were just an experiment that confirmed James Webb’s data with data from the rest of the missions. What the missions there would do in years, James Webb would do in a few days.
The Mars image analysis is part of the Cycle 1 Guaranteed Time Observation (GTO) program in which James Webb will examine the Solar System.
