To type in a handful Martian sand and to be surprised what it rusty. Then to go farther. To enjoy a beautiful landscape. it is possible to stop and drill Mars on 200-500 metres and to take from depth samples of a ground. Then somewhere for 1000 kilometres from a landing place to get rid of a backpack, to lift a returnable rocket and to start on an orbit, or return on base.
