The announcement is contrary to the impression left by the words of the head of the Curiosity project a few weeks ago. The findings were discovered through the activation of all the sample testing instruments inside the vaporizing SUV Curiosity
Uncomplicated chemical compounds have been discovered on Mars, but not organic substances. This is what the NASA scientists who operate the Curiosity rover announced this evening. This is in contrast to what the chief scientist in the project, John Grotzinger, said to the NPR radio station and which caused echoes all over the world.
NASA scientists operating the Curiosity rover used the entire array of instruments to analyze a soil sample from Mars for the first time. In this sample, complex chemical substances were discovered in the soil of Mars, including water and compounds containing sulfur and chlorine and other substances found in the inspection of the contents of the excavation arm that were transferred to the analytical laboratory inside the vehicle.
The discovery of these materials during such an early phase of the mission demonstrates Curiosity's capabilities to analyze the variety of rock and soil samples that will be collected over the next two years. The scientists also verified the capabilities of the Curiosity instruments.
Curiosity is the first Mars rover capable of digging into the ground and transferring the sample to test instruments. The specific specimen is in an area of wind-blown dust and sand drift known as Rocknest. The area is in a relatively flat area of Gale Crater, many kilometers from the destination of the mission - the steep slope known as Mount Sharp. Curiosity's chemical laboratory includes the Sample Analysis at Mars (SAM) kit and the Chemistry and Mineralogy (CheMin) instrument. SAM uses three methods to analyze the gases emitted from the dusty sand when it is heated in a small oven. One of the sub-instruments inside the SAM is used to detect organic components in the sample - compounds containing carbon, which may be the building blocks of life.
"We have no direct detection of organic materials on Mars at this point, but we will continue to look for them in the diverse environment of Gale Crater," says SAM principal investigator Paul Mahaffey of NASA's Goddard Space Center in Maryland.

Ronit,:
1) Maybe you can explain to us why the Almighty created (for evil???) the earth (in the Bible, by the way, this is an unfamiliar concept), for the sake of man.
2) What does it mean "we will profit"?
UAU And once again it has been proven that there is no life outside of the earth that was created by God for man and the mitzvot of the Creator must be fulfilled so that it benefits us.
Well, here's another rumor dissipating…
I'm still not sure if the head of Project Curiosity spread it, or if people just misinterpreted his words...
In any case, it is better to underestimate and surprise than to glorify and disappoint..
Anyway, how do they choose the landing spot? Why not land near the poles, or near a location where volcanic caves are suspected?
What is the specialty of the crater?
For a scientist, the normal operation of the chemical laboratory on Mars is historical knowledge, but for the general public historical knowledge is at least the discovery of a living and talking parrot on Mars...
The mountain gave birth to Apache. Not even a mouse…
Viking did not move from the landing place, therefore it is not defined as a vehicle but as a lander
Curiosity is not the first space vehicle capable of digging into the ground and transferring it to test instruments, it was preceded by Viking already in 1977 who did a similar experiment: http://en.wikipedia.org/wiki/File:Mars_Viking_11d128.png
And even then they claimed to have discovered life...

(There are of course also many other sources on this)
It's interesting that after 35 years, history simply repeats itself...
However the big difference is that Curiosity can also travel, which was not possible in Viking.
How long will it take for man to start planting trees and bringing water to Mars.... And if they start the Mars resuscitation operations, approximately how long should it take????
I want to emphasize, actually simple organic compounds of carbon, hydrogen and chlorine were discovered. It is not clear whether they originate from the pollution of the SUV itself or whether they originate from the ground. In any case, these are relatively simple organic compounds.
The mountain gave birth to a mouse. No "earthquake". No result "that will be written in the history books", maximum result "that will be written in the books of hysteria".
As I mentioned and others mentioned - there are organic substances in the solar system that were created from minerals in processes that are not life processes but in basic chemical processes. Therefore, there is no surprise in the discovery of organic materials on Mars, even if they are discovered.
Below is an objective description of the current findings as given by the Israeli astronomer Dr. Yigal Fat-El (if I'm not mistaken, Yigal Fat-El is the head of the Israeli Astronomy Association).
A quote from the words of Yigal Fat-El below.
======================
I write this mainly because of all the rumors about a sensational press conference that NASA was supposed to hold.
Well, the news that the systems are functioning perfectly is also good news, but there is nothing exciting in the findings that was not known about Mars or anything that has not been found before (with the exception of a compound containing carbon of unknown origin - perhaps in the vehicle itself - but it also may not indicate the existence of life ). Therefore, the two important points are that water molecules are indeed found in the soil of Mars, as we have already seen in the previous missions, but it is more important (following that major rumor) that so far no organic compound has been unequivocally discovered on the soil of Mars (here is the source to mention that organic compounds were found in the system our sun, for example in comets).
But, this is just the beginning. You have to give them time.
