NASA’s Mars Reconnaissance Orbiter took a fantastic picture of the north pole of planet Mars revealing stratified rusty red soil and frozen water and carbon dioxide. The astronomers compared the looks of Mars with a tiramisu cake: “This image of an exposed section of the north polar layered deposits (NPLD) looks much like a delicious slice of layered tiramisu.”
The greatness is that it is scientific evidence that there might have been water on Mars, thus life. Some of the astronomers wishfully believe that Mars is an old Earth. That it once hosted life. Maybe not like the one on Earth, but life nonetheless.
“If carbonate minerals were formed on the Martian surface by chemical reactions between water and the atmosphere, the presence of these minerals would be a clue that water had been present for a long time–perhaps long enough for life to have developed,” stated NASA.
Further studies are needed to prove the Mars had water and life
Those are just suppositions. Mars Reconnaissance Orbiter (MRO) can only bring evidence that triggers suppositions. It is a multipurpose spacecraft designed to conduct surveillance and exploration of Mars but only from the orbit. It contains scientific instruments such as cameras, spectrometers, and radar.
Their purpose is to analyze the landforms, stratigraphy, minerals, and ice of Mars. It paves the way for future spacecraft, such as NASA’s Mars 2020 rover, by monitoring Mars’ daily weather and surface conditions, studying potential landing sites, and hosting a new telecommunications system. It has enough fuel to keep functioning until the 2030s.
Scheduled to launch later this year, NASA’s Mars 2020 rover will perhaps bring scientific answers for the tiramisu appearance. The rover will be sent there to drill to find clues about Mars’s ability to host life. Recently, the rover got a name: Perseverance. It will seek signs of past life, return to Earth compelling rock core and soil samples, and demonstrate technology needed for the future human and robotic exploration of Mars.
