* Is There Life on Mars? : )

Mars is the best hope for resolving the ultimate mystery of creation. We are not alone who live in the earth. Mars enough likes Earth and called the "Second Genesis". There are robots in Mars which are orbiting three satellites and landers. Mars is a busy place to fine secrets and wealth of clues. Peter Snith has seven mission to Mars. In 1999 The Mars Polar Lander is to touch down on the surface, but it didn't come a signal at all. His next mission is Phoenix that finally arrived in Mars. NASA and Phoenix sharing supervision of the mission with scientists. Phoenix has landed that is the 39th times tried to reach Mars. The first attempt is the Soviets during the 1960s. When scientists get a first data that is the sense of astomishment and Mars is just barren desert.

These are ingredients for life : Three things to begin. One is an energy souce like heat. Two are organics. Third is scarce in our solar system. However, most important thing is liquid water. In the past there is some article in newspapers. "Mars was dead," quote. NASA has been explorated "follow the water." The is the most important first things. In 2004, NASA put wheels on the ground. They could see signs of water. Most of the rock on Mars is volcanis stones that thet were laid down in liquid water. The place was found on underground. Mars also have holes that is cleanly rated hole. The rock is 40 percent sulfate salt, and water was produced by rocks.

* My opinion : )

I would like to know about another planet which contains the Mars, so I chose this topic. I'm usually wondering about that "Can I live in another planet?" According to the vedio, I got some informations. If I get a chance to live in the Mars, I actually don't want to that. However, It is good news which is found by examination in the future. I think people will exhaust a natural resources and land also. Therefore, perhaps we have to fine alternative energy and another place. I mean, we should pay attation like this article and video.

The bright future is up to us : D
