Studies have suggested that Mars’s surface was once wet. The planet was home to an ocean of water. Water was present in its real state that covered the planet’s entire surface. However, the Red Planet’s water dried up. The planet today is a frigid desert. NASA and several other world agencies are exploring Mars. They are searching for the possible signs of life on Mars. NASA has landed multiple robots on the planet’s surface. The latest being is the Perseverance rover. It arrived at the Red Planet in February. It is exploring the Jezero crater. The rover has shared new insights with the US space agency. It has revealed that Mars once sustained interactions with water.
NASA said that Perseverance has explored the crater’s floor since its arrival. Scientists believe that the Jezero crater hosted lakes similar to those on Earth. Scientists decoded the detailed photos of Mars sent by the rover. Scientists said that images reveal that the crater had a fan-shaped river delta. It experienced flooding at a later stage billions of years ago. This flooding carried debris and rocks into the crater from outer areas. Mars had then thick atmosphere. It supported water to exist in the liquid form. Water was flowing across the Red Planet’s surface. The images show the mouth of a river. The ancient river filled the Jezero crater’s lake. The pictures also offer insight into where Perseverance can next hunt for Martian rock and sediment samples.
The rover had in September collected two Martian rock samples. According to NASA, the samples will give a detailed insight into the Red Planet’s history and evolution. It has named the first sample Montdenier and the second Montagnac. While the first sample was collected on September 6, the second sample was retrieved on September 8. Both samples were collected from the same rock. This was the second attempt by Perseverance to collect samples. The rover had in August made attempts to collect samples but it failed. The samples show signs that the rock that Perseverance drilled was in contact with water for a long time. The rover was launched by NASA to search for signs of microbial life on the planet. The samples will be brought back to Earth probably by 2029.
