This is a picture taken of the Martian surface from Viking lander 1 (There were two Viking Landers). This scene shows a rocky field. Patches of drift material and possibly bedrock are visible in the distance.
Future Mars missions will learn more about the Red Planet and perhaps pave the way for the creation of a human habitat. We cannot take everything to Mars that is needed to sustain the lives of colonizers. Mars itself would need to provide most of the colonizer's needs. Does Mars now have everything we need?

• There are many necessities for human existence. Make a list of what you consider necessary for human life. Your list would have those things you must have to live--without them you would die. Be specific.
• When done, you should discuss your list with others. Make a new list of the five most important things for human survival.
