Findings collected by the Mars rover Spirit gets scientists excited for what other secrets the Red Planet may hide

Scientists have conducted a lot of research to discover signs of water and possible life on Mars.  A recent discovery by a NASA rover has created excitement in the scientific community: the Mars rover Spirit collected soil samples that makes scientists strongly believe Mars was once wet. 

The rover found some Martian soil with high levels of silica, which needs water to crystalize.  Basic chemical analysis on the soil revealed the soil composition contained up to 90 percent silica.  This soil, located in Gusev Crater, is the strongest evidence that water, at some point in the planet's history, existed.

Scientists are unsure how the silica deposit in the crater originally formed.  The most likely theory is that soil mixed with acid vapors, created by volcanic activity, along with a strong presence of water.  Another popular idea is that the silica was created from water from a hot spring.

Spirit's discovery "reinforces the fact that significant amounts of water were present in Mars' past, which continues to spur the hope that we can show that Mars was once habitable and possibly supported life," said Doug McCuistion, NASA Mars exploration program director.

Oddly enough, the silica discovery happened due to a Spirit mechanical problem.  The bright patches of silica-rich soil were discovered when one of the rover's wheels dragged through the topsoil, revealing the bright colored silica-soil underneath.

Scientists are anxious to continue their research to discover what else is on the Red Planet.  Research indicates ice under the Martian surface varies in depth from location to location.
Late last year, NASA researchers used the Mars Global Surveyor to discover water flowed recently on the Red Planet.

Large rift across mars

The large rift that goes across mars is formed by a close encounter with the not so spoken of 12th planet called Nibiru / Marduk, that formed all the water into silica in a "vulcanic" event, like in a big part of the planet was ripped up.

Before that Mars was a planet a bit like ours, but even more important, soon Nibiru/Marduk is to hit Earth, as we can do nothing or so it is descided, it is politically vise and better to tell nothing about either who or what we are, just as certain history is not important to tell or even important not to tell, just as there is no point in telling a for many people scary future, but when our 12th planets enters the inner solar system once more, it is our turn, it will be the seventh and last time for US to see Nibiru / Marduk up close, that is what all the calendars such as Maya, inka, Vedan, Tibetan, Egyptian calendars where made for, to calculate that and off course one more thing regarding us as a species/container.

Nibiru / Marduk is over double the size of earth, it will be seen as a red glow on the sky when it comes near, so it was observed all the other times.

It has a long eliptic course that makes it take between "3600(Tzolken)-3661 (Sumerian-devine 60 system)" years of travel to do one cycle, it only enters our inner system for a short period of years, most likely we will only be able to see it 4-6 years before by our own eyes and only 2 years before due to the heavy light polution if you are in a populated area.
