  • NASA says the minerals and rock deposits at Salda are the nearest match on earth to those around the Jezero Crater.
  • Jezero Crater is the place where the spacecraft (Perseverance) landed.
  • It is also believed that Jezero Crater have once been flooded with water.
  • The rocks along the shoreline of Lake Salda in Turkey were formed by microbes that trap minerals and sediments in the water which was once a major life form on Earth.
  • NASA's Perseverance rover, now housed in Mars, will investigate whether there are microbialites in Jezero Crater.
  • It will also compare sediments collected from Lake Salda with fossilised remains at Mars.
  • This will help to understand the differences between the Mars sediments and Lake Salda.
