15. An account written in 2185 Our work on Mars actually began in spring, 2030. The first expedition arrived and began to construct underground buildings, conduct experiments, look for good sites for future landing and check for signs of life. Since there was almost no oxygen, they had to wear spacesuits. Many more expeditions came later. Around 2045, they began melting the polar ice caps by putting solar mirrors in orbit. They also made the atmosphere thicker by releasing chemicals into the air. When it got warmer, they began farming. Plants which were introduced from Earth on Mars could be converted into Oxygen. In 2130, it got warm enough for the ice to melt and for rivers and oceans are made. People began to migrate from earth. With more trees planting, Mars look greener. By the time I arrived, in 2160, Mars was more like Earth. The air is breathable. Inhabitants can move around without spacesuits. Everywhere you looked, you could see cities, farms and industries.
