Xeelee Sequence Edit

In the book Xeelee: Vengence, the Xeelee, godlike aliens from the far future, use time travel to go back in time to the year 3646 to destroy humanity. The Xeelee is undecided on whether to attack Earth or Mars first. Harry Poole comes up with the idea to make Mars seem like the dominant planet by using holograms of aliens and humans going to war against one another, and huge cities on its surface. This causes the Xeelee to choose Mars to attack with its 'planetbuster' beams. It creates an enormous tetrahedron that encompasses Mars, and then, from each vertice comes down a laser that slowly melts Mars into a ball of magma. By this time, most of the population was evacuated to Earth or the moon.


Sometime in the early 21st century humans visit Mars and find the Traveler. This starts the Golden Age where humanity colonizes much of the Sol system. During this period the city of Freehold was founded. After the Golden Age ended via the Collapse, Mars was taken over by the Cabal.

The MartianEdit

In the 2011 novel The Martian, the American space program NASA has sent two missions to Mars, named Aries I and Aries II. The events of the novel show Aries III astronaut Mark Watney as he is stranded on Mars for nearly two Earth years.
