NASA finds 3 bn years old organic molecules in rocks on Mars
Washington, June 8 : NASA announced on Thursday that its robot explorer Curiosity, which landed on Mars in 2012 and has been exploring there ever since, found organic molecules in rocks formed three billion years ago, a discovery that could indicate that there was life on the Red Planet at that time.
Paul Mahaffy, Director of NASA's Solar System exploration division, said that although this is an exciting discover scientists still cannot confirm how the molecules originated.
They could be evidence for the development of ancient life on Mars but they could also have come from a meteorite or other sources, Efe reported.
Despite the fact that it is still not clear how these molecules were created, NASA emphasized that these kinds of particles could have been the food source for hypothetical microbial life on Mars.
Jennifer Eigenbrode, with the NASA's Goddard Space Center in Maryland, said that the organic molecules found on Mars do not provide specific evidence of life since "they could have come from things that are non-biological".
In any case, however, the molecules may provide key information to scientists in their continuing search for life on Mars, since "All life that we know of is based on organic molecules," Eigenbrode explained.
She said that although the surface of Mars is presently "inhospitable", indications are that in the distant past the Martian climate allowed liquid water to exist on the planet's surface.
The data gathered by Curiosity reveal that billions of years ago there was a shallow lake of water inside the Gale Crater on Mars that contained all the ingredients necessary for life as we know it, including chemical building blocks and energy sources.
Eigenbrode said that -- now that potential signs of ancient life have been found -- future missions to Mars will delve deeper into the issue of organic molecules and other possible markers for life.
Curiosity found the first indications of water on Mars in 2013 and it also determined that the concentration of methane in the planet's thin atmosphere fluctuates regularly with the Martian seasons.
Although the origin of the gas is unknown, scientists say it could have been trapped underground as a byproduct of organic processes in the distant past and is now slowly seeping out.

RSS man's defamation case against Rahul: Key witness unavailable, hearing adjourned to Dec 20
Thane (PTI): A court in Bhiwandi in Thane district on Saturday adjourned the hearing in the criminal defamation case filed against Congress leader Rahul Gandhi by a Rashtriya Swayamsevak Sangh (RSS) worker to December 20 due to non-availability of a crucial prosecution witness.
Advocate Narayan Iyer, counsel for Rahul Gandhi, confirmed the adjournment, stating that the witness, Ashok Saykar, currently Deputy Superintendent of Police in Barshi in Solapur, could not remain present due to personal reasons.
Saykar's evidence is now likely to be recorded on December 29.
His testimony is considered key because he, as police sub inspector in 2014, conducted the preliminary inquiry into the private defamation matter under Section 202 of the Code of Criminal Procedure (CrPC).
It was on the basis of Saykar's submitted report that the court subsequently issued process (summons) against Rahul Gandhi under Section 500 of the Indian Penal Code (IPC).
The criminal defamation case was filed by local RSS worker Rajesh Kunte following a speech given by Rahul Gandhi at an election rally near Bhiwandi on March 6, 2014.
The case stems from the Congress leader's alleged statement that "the RSS people killed (Mahatma) Gandhi."
The matter is being heard by Bhiwandi Joint Civil Judge, Junior Division, P M Kolse.
The hearing had previously been adjourned on November 15 after the complainant's counsel, Advocate Prabodh Jaywant, moved an application seeking permission to examine Saykar, who had submitted the probe report to the court.
The matter was originally scheduled for November 29 but was deferred to December 6 after Rahul Gandhi's legal team sought an adjournment citing their non-availability. The proceedings will now resume on December 20.
