After years of hoping to find direct evidence of ice on
Mars, and after three failed missions, the scientists at NASA are finally about
to see their dream come true. The Phoenix
mission is scheduled to land on Mars on May 25 in order to find and analyze
samples of the ice and soil of the planet.
The first mission that was aimed at this failed in 1999
after contact was lost during the landing procedure. In 2003, Beagle 2, the
European Space Agency’s mission that was looking for proof of life, had the
same fate.
The odds of landing this mission are not good. 55 percent of
the attempts to land on Mars have failed, and the steering rockets that are
used by the mission in order to have a more precise landing are part of a
method that hasn’t been used for 32 years. The propulsive landing system is
considered to offer better landing results for spacecrafts that are heavier,
such as the ones that could be used if a human mission would be sent to the
planet.
The scientists are mostly afraid of the 7-minute period of
time while the Lander will be steering through Mars’s atmosphere in order to
land in an area about two times larger that Hong Kong,
located near the planet’s North Pole.
After the landing, Phoenix
will use its robotic arm in order to retrieve samples of soil and ice from the
planet’s surface. The samples will then be analyzed using its small ovens and
spectrometers.
Scientists say that even if the mission is not aimed at
finding life on the planet, the results of the ice analysis might point in the
direction of whether life is or was ever possible on Mars.
