One day in Sept. 1997, MGS, or Mars Global Surveyor, had landed onto the Red Planet had confirmed it as a natural landform. Not everyone was satisfied since they wanted more proof for this. It was April '98, cloudy time of year on Mars, where people couldn't use their telescopes to see the Face for themselves. So, on April 8th, 2001, MGS gotten close enough for another look. They've took another picture using a better camera that could see anything clear like a airplane, a truck, or a Egyptian-style pyramids! Once they've gotten the picture, People were satisfied.
