Studying Mars and Earth meet
Therefore, the researcher declared that scientists study these Martian rocks that preserve
geological clues about his past in better condition compared to those on Earth matches
finding the pages torn from your book from the geological history of our planet.
Find out the way was Mars' past, the way it originated and evolved this planet provides
valuable information about how the Earth formed and exactly how life originated. Scientists
speculate that up to 50% from the life forms on Earth are bacteria found beneath the surface,
in rocks deposited several miles deep. The earliest forms of life found have become simple
microbes which could have originated underground. And this research team proposes the
same thing may occur on Mars.
During future exploration missions to get signs of life, researchers will need to decide if they
should focus around the study of rocks on the surface or underground remnants seek.
"Personally I do not think we should try to drill underneath the surface for evidence of past
life. Instead of doing this, we can easily study the rocks that naturally have surfaced
concerning the impact of a meteorite and appearance the deposits deep within the leaked
fluids for the surface, "says Joseph Michalski.
For this research, irrespective of Martian geological records containing water or otherwise
not, the analysis of such types of rocks "teach us much about the early chemical processes
taking place in the solar
The subsurface of Mars retains pages of these history on Earth that were lost due to the
movement of tectonic plates. So a team of researchers describes the Natural History
Museum in London (NHM) the need for rocks which were several kilometers below the
surface with the Red Planet. And its analysis is really a further indicator that props up theory
that Mars would have supported in the past some form of microbial life. If ever there is
bacterial life, they are saying, was probably underground.
"We don't know how life formed on Earth, but it's conceivable it was underground, and it was
protected through the harsh conditions would have on land through the early stages.
Nevertheless, due to plate tectonics, barely offer the first geological record of our planet,
therefore we may don't know the processes that led to the origin of life and its particular early
evolution, "said Joseph Michalski, geologist Natural History Museum of London and lead
author of this study, in a very press release.
The analysis with the samples revealed minerals and clays containing carbonate minerals

groundwater.
Meteorites that have hit the outer lining of Mars probes have acted as natural, because
because of them we're able to get rocks that have been several kilometers deep,
approximately 5 kilometers, the authors note. Exploration probes and missions of robotic
vehicles, as 'Curiosity', delivered to Mars have provided new clues concerning the planet's
composition. Specifically, in this study we analyzed your data collected by NASA's' Mars
Reconnaissance Orbiter (MRO) McLaughlin within the crater, that includes a diameter of
about 92 kilometers along with a depth of 2.2 kilometers.
To John Parnell, co-author on this article and geochemist in the University of Aberdeen
(Scotland), this research demonstrates how studies on Mars and on Earth are closely
related: "It is what we observed inside the microbes living underneath the continents as well
as in Earth's oceans. MARTE, MARTE, MARTE
