Rate the following essay on its writing, argument, and language skills:
The Face of Mars was discovered by one of NASA's Viking spacecraft in 1976. It has been discused that it was created by living organims, called aliens, or that it is just a natural landform of the planet. Although both answer could be true, the reasonable one is the fact that the Face of Mars is just a landform.

In 1998, Michael Malin and his Mars Orbiter Camera (MOC) team took a picture of what is called the Face of Mars. According to the text, "Michael Malin and his Mars Orbiter Camera (MOC) team snapped a picture ten times sharper than the original Viking photos. Later on in the text it is stated that, "When the image first appeared on JPL web site, revealing... a natural landform. There was no alien monument after all". This passage shows that when the first picture was taken, the technology was not as develloped as it is now. The scientific world has taken a big step toward technology and this new science has given scientists more information toward the solar system that were unknown before.

Nevertheless, after this research people were still not satiesfied with the fact that the Face of Mars is just a landform. They believed that the picture was not taken at the right place.

Scientists were determied to prove them wrong. So, they engage into a new study. It is stated that on April 8, 2001, Mars Global Suveyor took another look to the planet Mars. According to the text, "We had to roll the spacecraft 25 degrees to center the Face in the Field of view," said Garvin. "Malin's team captured an extraorinary photo using the camera's absolute maximum resolution." Each pixels in the 2001 image spans 1.56 meters, compared to 43 per pixel in the best 1976 Viking photo.", this quote shows that the scientists of this research took careful attention to their research to make sure they would obtain correct facts. Later on in the texts, it is explain that what came out of the picture was just a landform like the ones we can find on Earth. For instance, the Middle Butte in the Snake River Plain of Idaho.

In conclusion, even though it might be hard for some people to believe the Face of Mars is just a landforms, all the studies scientists have done shows that it is just a landform.
