Earth water=Mars water!!


Well,it seems that Earth may have more in common with the red planet than you may have thought!we all know that the Earth and her sister planets formed from the dust and materials left after the sun formed.that is correct.we also know that once the Earth formed,the heavier materials such as Iron sank to the center of the Earth to become its liquid Iron core-therefore we have magnetism.and just after this happened,some of the planets started colliding with each other,and from one of those explosions with earth,the moon was formed.
But what was worrying the scientists for so long is where did all the water on earth come from.the early hot was so hot that it would have turned us to ash within microseconds.and then the creation of moon happened,that did not help matters along but it just over heated the already hot planet.okay,so where did the water come from?
According to some scientists,the water could have come from comets.but recently NASA sent a lander to impact on the comet and after an analysis was done,they found that the water contained on some of the comets differed quite a lot from earth water.so if not comets,then how?well it seems that during the birth of the sun and the solar system,most of the water regrouped in the region of the outer and inner asteroid belt and since it is quite cold there,they froze.anyway the scientists have concluded that as Jupiter formed,its huge gravity field changed the orbits of so many thousands of asteroids which all have impacted on one planet or the other.i tend to believe in this theory more than others especially when you take the watery world of Europa into consideration.so if we take it that the water or most of it came from asteroids which impacted onto a cooling Earth,then the same asteroids must have also impacted and gave water to Mars as well.if that is true,then the composition of water on Mars should not very that much at all from Earth water.the answer to this question is much nearer than you think.well,it will be answered by the Mars lander that NASA has sent to the red planet for studying the buried ice cap.
who knows,the water we drink everyday could very well turn out to be Martian water!

mars,earth,nasa,water,

We are going to get a taste of Martian water!


NASA is going to send a mission to Mars come august titled 'phoenix'.this mission unlike other missions is going to be sent to the northern plains of Mars where the ice is alleged to be on the surface just slightly beneath the subsoil.this mission is all about ice,literally.the main objectives of this mission is to analyse the Martian ice for its components and any evidence of life in any form whatsoever.generally the scientists all believe that microbes should exist even in a barren atmosphere as long as water is present.
Well by next may[the landing time for Phoenix on mars] we will all know whether water exists on Mars and in a manner of speaking we would actually taste the martian water at least know what it is composed of.who knows,maybe in a few years we may even be drinking bottled martian water?!?
Phoenix is not going to have a soft landing according to NASA but instead going to crash into the northern plains of Mars.but unfortunately this time around,the camera would be left out of the mission.that is really too bad as those high res image of ice on Mars would be just fantastic.i guess we should all settle for just a telescopic image of the Martian polar cap for the moment.come next may,many of our earnest questions are going to be answered.whether water existed on mars and whether life is still there on Mars!
