In this particular essay, the mission, roles along with the responsibilities of MRO would be discussed in order to determine the effectiveness of the activities performed by MRO. Moreover, the instruments through which MRO has been assisted in order to seek evidences regarding the persistence of water on Mars surface for several years would also be discussed in the essay. In addition, the discoveries and related snapshots would also be depicted in the essay.While determining the mission, roles along with responsibilities and the scope of MRO, it can be apparently observed that the aspect of MRO comprises certain effective scientific instruments for the purpose of analyzing the stratigraphy, landforms, ice and minerals present in Mars. In this similar concern, the instruments can be observed as radars, cameras, sensors and spectrometers among others. Specially mentioning, the above discussed instruments assist future spacecraft in terms of scrutinizing the prevailing surface as well as weather conditions in Mars. Moreover, the instruments aid in studying effectively the prospective landing sites and most importantly hosting an innovative telecommunications system. Notably, MRO is regarded as a mission, which has been designed by NASA in order to analyze the atmosphere, weather and geology prevailing in Mars. The studies conducted by MRO reveal the identification of the deposits of minerals that had formed specifically in water in Mars over longer period of time and the evidences of shorelines of prehistoric lakes and seas. Moreover, the studies of MRO indicated the amount of deposits in layers that took place due to flow of water in Mars. After acquiring a brief idea about the studies conducted by MRO and its focus upon seeking evidences concerning the prevalence of water in Mars, it can be affirmed that it might attract the viewers or the individuals towards acquiring a brief idea about the above
