Use the Starry Night Enthusiast \({ }^{\text {TM }}\) program to examine the planet Mars. Open the Favourites pane and double-click on Solar System > Mars to view this planet from about \(6800 \mathrm{~km}\) above its surface. (Click on View > Feet to remove the astronaut's spacesuit from the view.) You can zoom in or out on Mars using the buttons in the Zoom section at the right of the toolbar. You can rotate Mars by placing the mouse cursor over the image and moving the mouse while holding down the mouse button. (On a two-button mouse, hold down the left mouse button.) Rotate Mars and zoom in and out to familiarize yourself with the different surface features. Based on what you observe, where on the Martian surface would you choose to land a spacecraft to search for the presence of life? Explain how you made your choice.
