It could be a sign, a vague one.
A NASA rover has found the building blocks of life on Mars. They might be the product of past or present life on the Red Planet — or they might not be.
Either way, the samples of organic matter in the atmosphere and in rock show that Mars may at least have once had conditions favorable to hosting life, NASA said in a statement. They also show that the planet is still chemically active.
The Curiosity rover’s tapping into organics in rock is the first find ever of life’s building blocks on Mars’ surface.
Gas blast
The rover has run into pockets of gas on Mars: methane, often used to fire up gas stoves back on Earth.
Organic matter is made up of carbon bonded with other elements, often hydrogen and oxygen. Living things are made up of it, but life is not necessary for it to exist.
Methane is the smallest organic compound, consisting of one carbon and four hydrogen atoms.
On our planet, methane is a fossil fuel, but it can also rise out of rotting sewage or fly through the air in flatulence.
In other words, it usually comes from something living, or something that was once alive.
No life found
That could be the case on Mars, too, NASA said in a statement this week.
But the space agency carefully points out that methane can also come from inanimate sources as well.
“There are many possible sources, biological or non-biological, such as interaction of water and rock,” said Sushil Atreya, a scientist on the Curiosity team.
At this point, NASA doesn’t know if microbes are behind the gas or just minerals.
Researchers used Curiosity’s instruments a dozen times to get a breath of methane, and four of those times, it peaked at a level 10 times higher than usual.
They believe it may have been puffed up from the ground like little burps.
Organic rock
Curiosity also found organic matter while drilling into stone.
“This first confirmation of organic carbon in a rock on Mars holds much promise,” said scientist Roger Summons, who works on the rover team.

Since I’ve read this news, I have been thinking three things. First, maybe Martians could have eaten too many beans:) Second, or maybe the other species used the planet Mars as a garbage dump and they may have thrown their trash to the Mars for centuries, thus, methane gas come out:) What will the earthlings make in this situation? My third thought was over it. For evaluating this methane gas, the mankind will think to make truck farm, bringing humus soil and fertilizer to Mars:) I know all three are not serious but I cannot think another reasons and results:) In the meantime, it is really good to see you and your news again, a couple days later:)
