Changing the Blue Planet for the Red one? by Martina Harvanova

It seems like in the future our Earth won't be enough for the world's population. Countries such as India, China or Japan with the biggest density and still growing population rate probably won't be able to balance the number of its inhabitants and the given space and resources for them. Mainly that is a reason for thoughts about discovering and finding another possible place for humans. The most thinkable solution viewed by the scientists is considered to be a life on Mars, a planet where humans could be able to survive.The fourth planet from the Sun in the Solar System appears to common viewers as a ball of yellow, orange or reddish color. Mars disposes of two moons, Phobos and Deimos and its apparent magnitude reaches -2.9, a brightness surpassed only by Venus, the Moon and the Sun, though most of the time Jupiter will appear brighter to the naked eye than Mars. The rumor that on the Mars there might be liquid water is based on various observations which assume that the light and dark patches seen in periodic variations look like seas and continents. Moreover, the straight line features reminded the scientists of channels for watter, but in spite of the fact they were proven not to exist as they were explained as optical illusions.So how efficient are the researches and what are the latest news in the exploration of Mars? Evidence suggests that Mars was once significantly more habitable than it is today, but there is still no proof living organisms ever existed on the planet. The requirement for the Mars' habitability - the ability to develop and sustain life & is mainly that the orbit of it lie within a habitable zone. That means the water would not be in danger to freeze and this condition is currently fulfilled only by the Earth. The past flow of liquid water, however, demonstrates the planet's potential for habitability. The past flow of liquid water, however, demonstrates the planet's potential for habitability.The research about the possibility to find life on the Mars has recently moved forward as the specialists from the European Space Agency (ESA) have unveiled 3D pictures of the Mars to help understand and explore planet's unique topography. Thanks to the data from the Mars Express High Resolution Stereo Camera researchers will be able to obtain even more information about the Red Planet. Therefore the ESA claims:"Although ordinary images can give spectacular bird's-eye views, they can only convey part of the picture. They miss out on the topography, or the vertical elevation of the surroundings. That's where Mars Express comes in."Though the views are admirable and look really beautiful, I still have difficulties to imagine a real life on the Mars. Consequently, I hope the scientists won't rush with their researches. I don't plan to move out from the Earth.
