There was life on Mars and Titan?
28 missions NASA is considering the future to help find aliens.

VIVAnews - The existence of extraterrestrials or alien is still unknown. Scientists so far have not found the existence of creatures ET (extra terrestrial) it.

However, they did not surrender. Based on our belief is not alone in the universe, scientists will always make a breakthrough to determine where and how to search for alien life in space missions in the future.

Wednesday, April 28th, 2010 ago, scientists gathered in alien search astrobiologi conference in Houston - as well as celebrating 50 years of research astrobiologi.

Scientists say they are still vibrant and courageous to continue to seek another life in the universe. Although renowned astrophysicist Stephen Hawking has warned people not to communicate with aliens.

Hawking said, once we open contact with them, aliens can occupy the earth and suck its resources.

"We are very interested in and prepare to find another form of keidupan universe," said a senior astrobiologis at the headquarters of U.S. Space Agency, NASA, such as pages loaded Space.com, 28 April 2010.

Meanwhile, planetary scientist from Cornell University and researcher on the project of exploration of Mars, Rover, Steve Squyres, said NASA scientists are considering the future of 28 missions that can help find life beyond Earth.

"Astrobiologi and the search for other life is the main thing that we should order suraya kedepankan in future exploration," Squyres said.

A number of robotic missions - sending robots into the solar system, including visiting the planets Mercury, Mars, Jupiter and Saturn, or even farther than that, through the Milky Way, must be done in the future.

Especially to Titan, Saturn's satellites have lakes of methane and ethane, and Enceladus, with water vapors. Titan looks like a place you can live a life.

Mars

NASA Squyres added, also is considering an ambitious mission to Mars that will bring the Red Planet's rock samples to Earth.

"This mission will reveal many things, about whether Mars ever save a life," he said.

Likewise, researchers from the University of California, Los Angeles, Bill Schopf believes, examples of rocks from Mars or other planets is the key answer to the riddle of life beyond Earth.

"If space missions back tomorrow and take samples of rock, I will bring the stone to the lab. From there, this problem can be solved," said Schopf.

Schopf and other researchers, Jack Farmer of Arizona State University, previously announced study results, that they found that the type of mineral deposit called sulfate save ancient organism fossils. Sulphates are also widely available on Mars.

It is probable, sulphates on Mars also keeps a track record of life, just as on Earth.

In addition to planets and satellites, another place that might preserve evidence of life is an asteroid.

They have announced yesterday for the first time Wednesday that they have found direct evidence of frozen water and organic compound - - which is life-supporting materials. Especially the main asteroid in the vicinity of Mars and Jupiter.
