This article is relying the exciting information about water
on Mars. The NASA Curiosity rover has been hard at work retrieving information
for scientists back on Earth to analyze and evaluate. One such discovery was
that there was water in a fine-grain part of the Mars dust layer. The Curiosity
rover used its many drills and sample analysis programs to send information
back on this new find. Scientists in France and America were able to conclude
that there was indeed water in the soil. The author of this article is Amina
Khan, a renowned reporter in the scientific community. She has written many
stories about the world of science and even has a section in the Los Angels
Times devoted to scientific discovery. She does this because she wants the
public to be more educated on the interesting and fascinating world of science
that is happening around them. She wants to address the masses, or genera
public because most of them would not take time out of their day to read a
scientific journal to find advances in science. She uses easy vocabulary for
everyone to understand and tries to make the subject matter interesting to
everyone. Amina is able to use quotes and studies from the many universities
and labs to establish her credibility. There is appoint in the article where
she references the people at the University of Toulouse explaining that they were
the first people to say that the dust that contained water was not similar to
the dust that Curiosity first landed on. Referencing to the many universities establishes
her credibility and allows readers to get interested in the subject matter,
which is essentially her purpose. I think that the author was definitely able
to achieve her purpose in this article. She establishes her credibility and
makes finding water on Mars very interesting.
