With the information gathered, NASA scientists have identified topographic maps of the Martian surface, including sand and pebbles with the underlying rocks. From the results of the analysis of the composition of 6 types of rocks on Mars, scientists believe that volcanoes were once very active and had hot springs and a large amount of water exist on Mars. The layers of sedimentary rock indicate that the change from dry to humid conditions took place 3-4 billion years ago, and this transformation takes place periodically.

The Spirit lander successfully explored the mysterious surface of Mars for one year on this planet (equivalent to 687 days on Earth) and has begun to enter the second year for 3 weeks; while the Opportunity vehicle will also turn into the second Mars year from December 11.

Although the design life of these amphibious vehicles has been long gone, they still work well through all seasons on Mars and are being challenged by the possibility of survival in the upcoming winter. on Red planet.
