NASA (Space Agency American) said it will release this Thursday important details about the atmosphere of Mars, promising to reveal the “key” to understand the composition of the layer that surrounds the planet.
ad will be broadcast live by the agency official website, directly from Washington.
Among the event speakers will be Michael Meyer, chief scientist of the Mars Exploration Program, and Professor Bruce Jakosky, principal investigator of laboratory atmospheric and space physics at the University of Colorado, USA.
What is currently known about the Martian atmosphere is that is very different from Earth and is mainly composed of carbon dioxide (95.3%) and with small amounts of other gases such as nitrogen, argon, neon and oxygen.
In addition, a study published in 2013 by scientists at Oxford University released a new hypothesis about the atmosphere of Mars.
Based on recent meteorites and ancient analyzes Martian rocks processed by NASA’s Spirit rover, was hypothesized that Mars may have had an atmosphere rich in oxygen for four billion years (prior to the increase of oxygen the Earth’s atmosphere, there are 2.5 billion years old).
The theory justify the fact that the rocks about 3.7 billion years have components that indicate exposure to an environment rich in oxygen, while the ‘young’ meteorites of about 180 to 1400 million years do not show high levels of gas.
The last time NASA promised a big announcement about Mars was in September, when the agency said they have found evidence of liquid water flowing in the craters and slopes. According to MRO images, which is in orbit around the red planet, located beds to 100 meters long (approximately one football field) and less than 5 meters wide
