NASA Mars exploration rover Curiosity finds possibility of life on Mars
NASA Mars rover shows Mars once had Oxygen. The discovery will help the NASA scientists to study the the evolution of Martian atmosphere.
A fresh probe by NASA's Mars rover could establish chances of presence of Oxygen in in Mars, which could have established the fact that Mars had an atmosphere suitable for life, say scientists.
NASA who had already declared about the presence of salt water on the red planet, has now discovered the presence of manganese in the rocks of the red planet. The study has motivated the scientists to think that the Martian atmosphere could have oxygen too.
Mars rover curiosity was send to the red planet to study its rocks in order to study about the chance for life on the red planet. The discovery will help the NASA scientists to study the the evolution of Martian atmosphere.
They stumbled upon presence of ‘Basalt' rock formations which is formed when lava gets cooled after an explosion.
Though most of the Martian surfaces have it, the rover was able to find the traces of manganese, while probing for life in 2013, said scientists.
Though Basalt has some amount of manganese, however the quantity the metal found in the sample of rocks indicated that it had a heavy deposit of the concentrated manganese.
This can be possible if basalt rock has been dissolved in oxygenated water. This established that the red planet had water once that could dissolve Basalt.
But once Mars had rich oxygen content is what emerges from the new study. To double check, Mars Curiosity has been sent to collect lot of samples from Mar's Gale crater. This time also they found manganese.
They presume that oxygen may have entered Mars through ionizing radiations,after Sun rays's helped in this regard by triggering a chemical reaction.
However, it might have slipped from its atmosphere since gravity is weak in the planet. Scientists say the study sheds light on how Mar' atmosphere evolved differently from Earth's. NASA will be looking for evidences of more elements from the Mar's planet.
