I would first take stock of available resources like food, water, and power. I would carefully ration my consumables, extending their usage for as long as possible. Additionally, I would establish a strict daily routine, monitoring my physical and mental health. To communicate with Earth, I would try to salvage parts from my damaged equipment, using my engineering skills to create a makeshift communication system. I would then transmit a distress signal with my location and wait for instructions from Earth on how to proceed.
Imagine you are an astronaut stranded on Mars. Describe how you would ration your resources and establish communication with Earth.
