Water On Mars?

Taylor W. -- Scientist at NASA may have finally done it. The may have found proof of water on Mars. On August 5th 2011 NASA scientists revealed that they had found dozens of dark streaks on the surface of Mars that they believe are a result of running water. This discovery was made thanks to NASA’s
powerful camera called HiRISE (High Resolution Imaging Science Experiment) that is aboard NASA’s Mars
Reconnaissance Orbiter. This orb has been taking pictures of mars for the last 5 years. The streaks were
discovered running inside narrow channels along the inner walls of a small crater called Newton, located
on the southern hemisphere of Mars. What puts this theory over the rest is that the streaks are not
permanent, but come and go depending on the season. When the planet heats up the water melts and
runs downhill, while during winter when it freezes, the streaks disappear again and repeat the cycle. It is
believed that it is from indeed water but not fresh water salt water b/c the winter temperatures would
indefinitely freeze the fresh water. This theory is not a 100% but it may help in the theory that mars was
once a warm and wet planet.

I think that this discovery is amazing. I think that the streaks on mars were caused by salt water. I also think that there was and that there is still water on mars. Maybe other than the ice cap it’s deep under the crust of mars. I agree with the scientists at NASA. Maybe if there’s water on mars, why not other planets. Neptune has a never ending storm on it maybe its core is not just a gas, maybe it’s a solid.
