In the era of 60s and 70s, mars were considered to be a dead planet by the scientists. Due to the robotic missions in past decades has gave many evidences about mars to be in active place. Recently an image by Mars Reconnaissance Orbiter that shows landslides in Nili Fossae. This area comes to the north of jezero crater a part of syrtis major region. The image was captured with the help of MRO’s Context Camera (CTX) as a part of landslide larger image. It was taken when MRO was above the surface of about 284 km which covers the image area of about 5 km.
The camera is designed in such a way that it provides the background views of rocks and minerals on larger scale. They also use other instrument on MRO to carry out the study like High-Resolution Imaging Science Experiment (HiRISE) and the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM). It also helps in taking the mosaic images of the surfaces that are useful for landing for future missions.
CTX is also responsible for observing the surface on mars that changes periodically. What has happened near the Nili Fossae crater from the images it has shown is that they saw a fall of material inside the crater since it was last captured. They also noted the same thing on the other side of the crater.This kind of incidents were termed as mass wasting process or slope process by the geologists. It deals with large landslides, rock falls, avalanches and soil creep etc. and the previous images have shown this all.
From the image the crater lies just north of the jezero crater which is the landing site of the perseverance rover. As we can see that this kind of features is mainly seen near the moving water on earth which slowly adds the sedimentary layer on it over time.
Curiosity rover after its successful landing in 2012 has been analysing the gale crater which gives the evidence that water was there on mars many years ago in the form of rivers, lakes and a large ocean. In spite of everything that life was there on mars or not but from all the evidence it is clear that the planet is alive. It indication of past and present features are very essential to distinguish the environment on mars.
