The title of my article is NASA’s 2020 Rover Will Search Mars for Signs of Life. The purpose of this article is to inform the audience about the possibility that life could have existed on Mars. The scientist at NASA believes there may have been life on Mars because of evidence of water. Water is one of the necessities that all living things need and so if a planet has water, there is a chance that there is life there. In order to find more evidence, NASA has planned to create a rover that will reach Mars in the year 2020 and will search Mars for evidence of life.

The author of the article used many visual elements in the article in order to describe the environment of the planet Mars. The article begins with a picture of what the rover was potentially going to look like on Mars. This picture is provided for readers so they have an idea of what the rover would look like and what it would be doing on Mars. The planet is described as red and throughout the article, Mars is referred to as the red planet. The article also provided a video of the surface of the planet Mars which allowed readers to actually see what Mars looked like. This video was helpful because it encourages readers to imagine how life could have been on Mars. Another example is when the article described a lake that was on Mars. The purpose of this was so readers could understand how life could have been on Mars. The article described a lake with a river system. Two rivers fed water into the lake and an outlet valley allowed water out. The way this lake is described on Mars helps readers visualize an ecosystem that could have been the home of various life forms.
