Are there life in Mars? Are we the only life forms in the galaxy? Those are just some of the
question that many people have thought about life in outer space and many scientist up till
now are still struggling to find the answer to those questions.
Adapted from ODYSSEY’S January 2001 issue:2001:a space odyssey, Wanted: Mars…
Dead or Alive? By Geoffrey A. Landis. Landis start the article by giving the first discovery of
Mariner 4 in 1965. The camera from Mariner 4 revealed that Mars have no sign of life and
have thin atmosphere and harsh condition, even though comparing Mars to the other planets
like Venus, Mars is more likely to have living organism.
Landis follows up with theory’s of how Mars has a potential to have an ocean or source of
water long ago. New photos of many features like riverbeds on the surface of Mars from the
robotic spacecraft that followed mariner and it’s later cousins backs up the theory. Further
discoveries were made from the Mars Global Surveyor, that Mars have a large low area that
could further support the theory of how mars could have had water in the past. The theory
continue to further explain that if Mars has water, than there are possibility of a living life
form in Mars. Landis explain that if life started when Mars’s atmosphere were thicker back
then resulting in a warmer climate there are possibility that the living things may adapt to the
change in environment to survive in the cold and dry condition of Mars today.
Landis further explain that because the theory of how the living things could have adapt to
the environment is unlikely because of the high level of difficulties to survive in the surface
of Mars. The life forms are more likely to be hidden in an underground water source
protected from the harsh surface of mars.
Landis ends the article stating that even though new discoveries and evidence of life forms is
still being search using rovers, some people thinks that the only way to answer the question
of whether life exist on mars can only be proven by an expedition into Mars itself.
My personal remark to this article is that it has a lot of scientific theories that are not easy to
understand but it is structure in an order that helps the reader understand the development of
the theory.
