A little interesting about space life.

Unfortunately, even though mankind has gone to the moon in 1969, this is still not a simple feat in the 21st century. Most of the know how accumulated during the lunar flights have been lost due to the fact that production facilities have been dismantled and many experts who worked on the lunar missions either have retired or died. Right now, it would be impossible to replicate the Saturn 5 rockets that were used to launch the original Moon Mission. Thus, due to this, it has become impossible to fly to the moon again without some sort of a preparation. Hence, many scientists state that going to Mars is a better option as compared to going to the Moon.



and here is another

NASA's Voyager 1 spacecraft was the first to visit Titan back in 1980. Although Voyager 1 made a truly heroic journey, it proved unsuccessful in its efforts to obtain close-up pictures of Titan's veiled surface. This adventurous, early space mission was not able to obtain the desired images because it could not cut through the dense orange smog--and the resulting images showed only some minor brightness and color variations in Titan's atmosphere. In 1994, the Hubble Space Telescope (HST) did succeed in obtaining some precious and revealing images of Titan's well-hidden surface--showing the existence of a bright and sparkling continent dubbed Xanadu--after the "Xanadu" of Samuel Taylor Coleridge's romantic poem Kubla Khan. Titan's Xanadu glitters as if lit by the cold fires of a multitude of sparkling rhinestones.



and finally

The most detailed pictures of Europa show even more intriguing clues that there is slush lurking beneath its brightly shining icy surface. Slightly smaller than Earth's own beloved Moon, Europa's surface temperature could easily freeze an ocean solid over a span of only several million years. However, some astronomers think that warmth from a game of tidal tug-of-war between Europa and Jupiter, as well as other neighboring moons, could be keeping large regions of Europa's subsurface global ocean in a life-friendly liquid state. This process is termed tidal heating, and it refers to a mechanism whereby the gravitational tugs of a nearby object (or objects) flex and bend and contract and expand another object continually. This constant churning causes the victimized object, in this case Europa, to heat up and be considerably more balmy than its great distance from the Sun would otherwise allow it to be.

More information:

The scientists modeled different temperatures and water abundances that may have been present in the Moon-birthing disk. At higher temperatures, their disk was primarily composed of silicate vapor, which formed as a result of evaporation of the mantles of both the proto-Earth and the doomed Theia. The disk at these higher temperatures also contained a relatively small quantity of hydrogen dissociated from water. In contrast, at lower temperatures, their disk was primarily composed of water, from which hydrogen did not dissociate under this cooler temperature range--thus making its escape mechanism very inefficient.



Our Moon's temperature reaches about 260 degrees Fahrenheit when under a full Sun. However, in darkness, the temperature dives down to approximately -280 degrees Fahrenheit.



Most of the moons of our Solar System are icy little desolate and dead worlds, dwelling in the dark, cold stillness of those regions far from the warmth and light of our Sun. However, a few of these small bodies may not be lifeless. For example, Europa of Jupiter may have a subsurface global ocean of liquid water secreted beneath its cracked, jumbled frozen crust of ice. This subsurface ocean might be warmed by tidal flexing into a hospitable, life-friendly liquid-water state, where primitive life-forms may swim around in the deep-sea darkness beneath Europa's ice. In addition, the second-largest moon in our Solar System, Titan of Saturn, possesses an environment that is eerily similar to that of our own planet long before life evolved out of the lifeless ooze (prebiotic). Big, lazy raindrops of liquid hydrocarbons float to the surface of this tormented, frigid moon, forming seas and lakes composed of methane and ethane that play the same role as water on Earth. It is entirely possible that life, as we do not know it, can evolve and flourish using liquids other than water. The largest moon of our Solar System, Ganymede of Jupiter, is larger than the innermost planet Mercury. Like its sister-moon Europa, Ganymede may hold secreted, beneath its surface crust of ice, a global ocean of liquid water. The little icy moon, Enceladus of Saturn, spews out geysers of water mixed with ammonia (which plays the role of antifreeze) from its so-called "tiger stripes". Therefore, Enceladus could also harbor life-loving water hidden beneath its icy surface.
