*I am an astronaut stranded in space. I am completely alone. I have lost contact with Earth, so I cannot call help. I am in my small spaceship in the middle of nowhere. I am running out of fuel, and my food supply is also low. There are two planets close to me. One of them is a really cold planet. One of them is a really hot planet. My scanners indicate that there is little water on the hot planet, and a lot of water on the cold planet. Both planets have a somewhat amount of food to obtain.
