Inspired from FutureTimeline.net and the Integrated Space Plan we have created a speculated timeline of human exploration and colonization of Mars. Predictions are based on a reasonably optimistic evaluation of technological and social progress of humanity. Only the most important and innovative events are mentioned. Timeline is regularly updated taking into account latest developments.

2060s – Nuclear fusion spaceships open up Mars
■ Mars City’s population reaches the level you can’t anymore made the decisions by corporate hierarchy or direct democracy only. First city council on Mars is elected.
■ The expanded Free Spaceport of Phobos more and more serves as a space logistics hub not only for colonies on Mars but for mining activities in Main asteroid belt as well. Several more space-faring nations begin participating in the spaceport project.
■ Several more orbital space stations are completed around Mars for in-space manufacturing, tourism and other purposes.
■ First humans born on Mars travel to Earth using exoskeletons as body-support because of Earths heavier gravity.
■ Commercial companies from various nations open their branches and operations on Mars.
■ Tourism from Earth is expanding on Mars. Although the trip is still expensive and only the rich can afford it. Besides its high-tech cities and bases Mars can offer spectacular safari rides and if you are really wealthy you can hire some of the guides to take you to the caldera of Olympus Mons, depths of Valles Marineris or other exclusive locations.
■ A second large-scale dome on Mars is constructed at Blue Mars. A hyperloop line is built between Mars City and Blue Mars.
■ First measures to start the terraforming process of Mars are made, powdering Martian polar ice caps with black lichen to reduce their albedo and melt the ice and building small automatic halocarbon factories throughout Mars to produce and release super-greenhouse gases in Martian atmosphere.
■ Artificial magnetic field generator is placed at Sun-Mars Lagrangian point L1 to shield Mars from solar radiation with the generated magnetotail and help the terraformation process of the planet.
■ Free Spaceport of Phobos is the starting point for international human mission to Galilean moons of Jupiter.
■ Nuclear fusion powered spaceships (greatly reducing the travel time from Earth and widening the launch window) bring more colonists to Mars than ever before. In 2060s the human population on Mars explodes from less than 10’000 to more than 50’000 with Mars City alone having 25’000.
2070s – Human outposts spreading past Mars
■ The Free Spaceport of Phobos is the main supply node for human outposts and missions to Ceres, asteroids in Main asteroid belt and Galilean moons of Jupiter.
■ Cyanobacteria and methanogens are spread in lower regions of Mars to further increase the terraformation process.
■ The old workhorse of human colonization of Mars – the BFR family Starships are finally retired completely. The oldest of them are 50 years old now.
■ Mars City is expanded with two more domes of similar size and several smaller ones.
■ There are 5 cities with large-scale domes now on Mars. All of them are interlinked with hyperloop lines.
■ The cluster of Indian colonies on Mars is starting to specialize on growing food for human space outposts in Main asteroid belt and beyond, as Mars is the closest object to them with substantial gravity and natural sunlight for growing crops relatively cheaply.
■ The Free Spaceport of Phobos is a starting point for international human mission to the moons of Saturn (Titan, Enceladus and other).
■ Now almost all of the space-faring nations are represented on Mars with a base, a city block or a corporate enterprise.
■ In 2070s the human population on Mars expands from 50’000 to 200’000 with the largest colony – Mars City – having 60’000. Four more cities have a population of more than 15’000.
2080s – Mars gets its self-government
■ First Martian Council, consisting of proportionally drawn representatives from every Martian city and base, is assembled on the principle of self-government. The Council deals with the issues important for all of the Martians (as ongoing terraformation initiatives or building a space elevator) and acts as a representative of the Martian population in relations with the corporations and governments of Earth.
■ As space elevators first on the Moon and then on Earth become operational, the cost of launching any mass to Mars and elsewhere into space is slashed considerably, greatly speeding up the use of space resources and space colonization.
■ Almost all colonists have left the oldest sections of former Mars Base Alpha with its obsolete infrastructure; the area is declared now a national heritage site, preserving the 1st human base on Mars as it was in the late 2040s and acting as a tourist attraction.
■ Tourism from Earth is becoming more and more mainstream. Now even a middle-class people can afford a trip to Mars.
■ Despite criticism China builds the first prison on Mars. Soon other colonies are quietly sending there their criminals too.
■ More powerful halocarbon factories are set up throughout Mars. The bacterial and lichen coverage around Martian surface is further increased.
■ Connected base stations for downward and outward space elevators on Phobos are built; work begins to construct both space elevators. The downward elevator will cut short of the upper edge of Mars’s atmosphere with a shuttle platform at its tip. The outward elevator will have several platforms at different points to catch and release payloads (including spaceships) to Earth’s system, to Main asteroid belt and to Jupiter’s system.
■ Work begins to build a large shuttle port at the summit of the Martian volcano practically on the equator – Pavonis Mons – for shuttles heading to and coming from Phobos space elevator.
■ In 2080s the human population on Mars expands from 200’000 to 500’000 with the largest of the Martian cities – Mars City – surging past 150’000 inhabitants. Particularly large colonial fleet arrives on 2082 when Earth and Mars is the closest since 2003, only 55.9 million kilometers (34.7 million miles) apart.
2090s – The millionth Martian
■ The Phobos space elevator system is finished, greatly speeding up the colonization of Mars, interplanetary trade and the growth of human outposts in Main asteroid belt and Galilean moons of Jupiter.
■ The shuttle port at the summit of Pavonis Mons quickly expands into one of the largest human colonies on Mars – Pavonis City, which is soon connected with other major Martian cities by hyperloop lines.
■ Establishment of Pavonis City greatly expands tourism in some of the most spectacular Martian regions nearby – Tharsis Montes, Olympus Mons, Noctis Labyrinthus and Valles Marineris. Tourist bases and hotels are popping up there fast. One of the hyperloop lines runs through all the length of Valles Marineris.
■ In an anticipation of air pressure and temperature increase, new human colonies are being set up mainly in the lower regionsof Mars, particularly Hellas Planitia and Valles Marineris, where the results of terraformation activities will be felt first.
■ In 2090s the human population on Mars reaches 1 million. Finally Elon Musk’s goal to put 1 million people on Mars is reached.
22nd century – Mars becomes independent
