ANSWER: Both of the above
 
No life possible on Mars!Mars is the basic target for scientists searching for life outside planet earth. Liquid water is the most important and critical prerequisite for life.
  • But global scientists have found that the Red Planet is incredibly dry and has been so for millions of years
  • More than 3 billion years ago, Mars was wet and habitable
  • Latest research reaffirms just how dry the environment is currently
  • Life is therefore not possible in Mars
  • Scientists examined a cluster of meteorites at Meridiani Planum- just south of the equator and at a same latitude to Gale crater
  • Researchers calculated the chemical weathering rate for Mars and how long it takes for rust to form from metallic iron present in the meteorites
  • Chemical weathering process depends on the presence of water
  • It takes 10 to 10,000 times longer on Mars to reach the same levels of rust formation on dries deserts on earth
  • President day aridity has prevailed in the Red Planet for millions of years
