Article Review Nasa Curiosity

Article Review NASA/JPL, “NASA rover finds old streambed on martian surface”. Astronomy. September, 2012. The article I’m writing about is about the NASA Curiosity Rover and how it’s doing on its trip to mars. The reason that NASA has sent this rover is to find potential signs of life on the surface of mars. They are trying to find evidence that there once has been enough resources to have any kind of life on mars. NASA has sent a rover to Mars called the Curiosity Rover. It is on its way to the slope of Mount Sharp in Gale Crater which is the rovers’ destination. On the way to the stopping point it has discovered something nobody thought would ever be in space. The Curiosity rover found evidence that a stream once ran vigorously across the area on Mars where the rover is driving. Scientists in charge of the rovers’ journey are studying pictures of stones cemented into a layer of conglomerate rock. "From the size of gravels it carried, we can interpret the water was moving about 3 feet [0.9 meter] per second, with a depth somewhere between ankle and hip deep," said by William Dietrich. The shapes of the rocks tell you they were transported and the size of them tell you that wind didn’t transport them. The shapes also tell you that the stream was flowing for a-long period of time and not just a couples years. NASA is finding materials on mars that are potential ingredients of life. The reason why the stream the rover has found is good because a stream could be habitable environment, which potentially means signs of life. People for years have been wondering and asking themselves if there really is some sort of life form anywhere else in the universe. I mean, the universe is huge so why not? Knowing that the NASA Curiosity Rover has found evidence that there once was a stream flowing vigorously across the surface of Mars. People can now see that there actually is a good chance that there is or has been life other than on the earth. If the scientist are
