The robot Curiosity de la Agencia Espacial Estadounidense (NASA) found new indications that sometimes there had water in Mars, according to the study that they carried out.
It landed in August 2012 in the crater Gale of the red planet equipped with instruments of high technology, took photos of several pebbles of smooth and round surface, very similar to those that are seen in the beds of the rivers of the Earth. The pebbles were found very near the crater Gale, the place of landing of the Cur.
Mars is an arid planet, the scientists found tests that the water flowed for his surface several millions of years ago. The robots of NASA Spirit and Opportunity already found on this day signs that there had water in Mars. The scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon, some of the essential chemical ingredients for the life.
Another of the great facts that NASA goes carry out goes to be to send human beings to the red planet in 2020. Than help of the Curiosity and the Opportunity (American spacecraft), and also with the participation of the Stipendi, European ship at present in the orbit of Mars.
In my opinion these researches have his advantages and disvantages. On a side, I would like to know whether there was life in Mars or there is possibility of there being someday, for the news that comes out, it seems that they go for the good path. But on the other hand these researches and journey to Mars cost a lot of money, and the world economy should haven’t this such great expenses.
