The Search Life and Water on Mars
Science is a field that is based on evidence that is gained from research. Research in
science is a process that continues and this leads to new evidence which replaces the older one.
The issue of life and water on Mars is one of the theories in science that have undergone
developments as a result of continued exploration (Fred, 2015). Even though much of what is
known by scientists about Mars is much sophisticated than what was known decades before there
are some unanswered questions that require more research to find answers to.
The issue of Mars caught attention of the people after astronomer Giovanni Schiapparelli
from Italy reported about the red planet in the late 1870s. Giovanni used a telescope to observe
canali, or channels on mars. Due to a mistranslation of the world canal, an American business
man named Percival Lowell founded an observatory in Arizona (Fred, 2015). It is in this
observatory where Lowell and his team observed the canals in Mars believing that the canals
were dug by intelligent beings. This belief brought the aspect of life and water in Mars as if the
canals were dug by beings then this was evidence that there was life in mars which could have
ended by the time Lowell made his observation or was still in existence (McKay, 2019). The
canals were also assumed to have been dug to channel water to certain areas for various uses.
However, in the 1960 when the first robotic spaceship was sent to Mars the belief that
there were some intelligent beings in Mars who had made some canals while looking for water
was proved wrong by photos that the spaceship sent back to earth. The photos from this first
scientific mission on Mars showed a desolate world which was marked with craters like the
moon. In 1975, the NASA’s Viking mission sent two orbiters and two landers to Mars. The
landers included some chemical experiments which were meant to look for evidence of life on
the planet but their results were all negative (McKay, 2019). The negative results of these

experiments deflated the hope of a world that was full of life. the Viking 2 discovery did not
bring to an end the process of investigating Mars but introduced a new angle. Future
investigations into the planet delved into the geology and climate of the planet. Looking at the
option of establishing life on the planet even if none has existed on the planet before (Shaghaghi
& Antonakopoulos, 2012). NASA scientists began collecting samples of Mar’s Rocks, air, and
soil to be brought back to earth for further investigations.
From these investigations, scientists have established that Mars is too cold, with a very
thin atmosphere that is too thin to support liquid water on the planet’s surface. Images captured
by the pathfinder and the Viking Orbiters took some channels that could have been formed by
flowing water and some other features that looked like ancient shorelines. The existence of water
in the past brings two conflict theories (Fred, 2015). One is that in the paster Mars was warmer
and wetter with a thicker atmosphere and thus allowing the existence of water in rivers and lakes
while the second posits that Mars has always been cold but water was trapped underground as ice
but it would melt during heating coming onto the surface (McKay, 2019). However, despite the
two competing theories, many scientists believe that the changes that happened in Mars were as a
result of climate change that made the Mar’s atmosphere to be thin to an extent that to could no
longer hold water in liquid form anymore.
With the problem of overpopulation facing the world, scientists have pointed Mars as a
possible world for some future generations. However, scientists are still struggling with several
issues. Key Among them is the issue of water which scientists have agreed can never stay in its
liquid form on the planets surface (Shaghaghi & Antonakopoulos, 2012). This is a question that
needs an applicable answer if human existence will ever be established on Mars. The second
issue is the issues of the thin atmosphere which comprises of the long gases with 95.3% of CO2

and too little oxygen and Nitrogen (McKay, 2019). If human existence is ever to be established
in Mars, then the composition of these gases has to be altered.
At first, people did not have much interest about Mars but with the continued scientific
investigations into the issue people have gained more interest and hope into Mars Exploration
hoping that the planet will turn into the hope for a better future someday (Shaghaghi &
Antonakopoulos, 2012). Even though many do not know the exact details about the discoveries
about Mars, many Americans think that continuing with the Mars investigations is a progressive
project that is meant to save mankind (McKay, 2019). However, a popular misinformation that
has been carried by the media for a long time about the existence of green aliens that feed on
human beings has made some people fear the exploration of Mars and any attempt to establish
there. These media stereotype has no scientific background and is based on human imagination
and therefore is wrong.
