Mission One landed the first ships on Mars, marking the start of the colony. Autonomous vehicles, controlled on Earth by the ISA, executed the initial setup of power, fuel, and water extraction systems. The entire process was managed remotely by ISA stakeholders on Earth.

The first crewed rocketship carrying four astronauts lands on Mars. Three additional cargo rocketships accompany it, carrying life support, equipment, and vehicles for expanding the colony. The astronauts begin setting up habitation modules, conducting scientific experiments, testing 3d printing, and exploring the surrounding areas.
This was rough, a little like camping, if you were to camp in a place where the temperature dropped to as much as -140 Celsius (-220 Fahrenheit). The astronauts worked hard, lots of eighteen hour days.

Another 8 astronauts arrive on Mars to help expand operations, exploration, and infrastructure. Larger inflatables are assembled to make life more enjoyable for the astronauts. Power and fuel generation is scaled up to support the larger base.
The 12 get up in their individual sleeping pods, and meet to eat together in the dining hall. (The astronauts eat a lot of their meals together). The doctor goes to the medical bay, Scientists research either in the lab, or use the rover to collect samples. If there was a martian sandstorm someone cleans off the solar panels. Botanists farm. Engineers maintain and build things.
In the evening they eat meals made out of tomatoes, peas, radishes, rye, quinoa and potatoes and, if they manage the tasks that are keeping them alive and have a little time in the evening, then hang in one of the two the social pods. They have hobbies, making either sculptures from the 3D printer, or maybe making regolith 'canvases' and Martian pigments–which hang in sleeping pods and the Medical Bay. Hanzou has introduced the game Go and there is a running tournament.

Mission Four is currently in progress to Mars. The mission brings larger structures, construction equipment, weather equipment (for monitoring dust storms), and additional vehicles. The construction-focused Civil Engineers are aboard the Crew Rocketship, and Geologists are also joining to help research. With a growing group of astronauts, it also becomes important to ensure a peaceful environment and diffuse and conflict in a diplomatic way. Security and psychology professionals will research, test, and study different approaches to prepare future missions for success.
