NASA has confirmed that
there is organic material on Mars and has indicated that it
"misinterpreted" the words of the mission's principal investigator
Curiosity, John Grotzinger, who last week claimed that the U.S. space agency
had an announcement "that would change the books of history.” Grotzinger
himself has said that the media "misunderstood" his words.
Thus, the NASA experts
have put an end to the expectations that had been created around the Fall
Congress of the American Geophysical Union (AGU), which opened Monday in San
Francisco, where he was to perform the course announcement finding life on
Mars.
So, finally, what has
made public the space agency is, what we already knew, that Curiosity has
analyzed, for the first time, the Martian soil with its sophisticated battery
of instruments and has been found in the area known as 'Rocknest' , a complex
involving chemical elements such as water, sulfur or chlorine.
During the conference,
scientists have noted that the mission is still in an early stage, so that they
are not able to confirm the presence of organic material. "We do have a
lot of work with this material. Need to be very careful. Could have been
degraded organic material by solar ultraviolet radiation," he noted during
the conference Grotzinger.
They have also pointed
out that the detection of substances during this first stage is being used to
test the ability of the laboratory and instruments.
For this reason, the
conference hosted by NASA has focused on enlarging some of the mechanisms carrying
Curiosity. The expert from the Goddard Space Flight Center of NASA, Paul
Mahaffy, explained that measurements were made with the three instruments of
the SAM (the analyzer samples the rover) and identified several gases, water
vapor and oxygen in small percentages.
The remains of water
are much higher than those that throw the Earth's ancient oceans and also
appreciated the presence of oxygen and sulfur. "But few organic
compounds," insisted the scientist.
Calm Within the message
launched by NASA, Grotzinger held a glimmer of hope ensuring that NASA is using
all its science instruments to examine samples of Mars facing the "main
target" of the mission, Mount Sharp ".
