I will first take an inventory of all available resources, including food, water, and oxygen. I will then create a schedule to ration these resources to make them last as long as possible. Meanwhile, I will attempt to grow plants in Martian soil to supplement my food supply. To maintain my mental well-being, I will establish a daily routine involving exercise, leisure activities, and documenting my experiences. Finally, I will find ways to communicate with Earth, using any available tools or technology, to report my status and await rescue.
Imagine you are an astronaut stranded on Mars. Explain your plan to survive until help arrives.
