Initial settlement by Humanity dated back to 2103 and was established by the United Earth Space Probe Agency who intended to use it as a support platform for further exploration of deep space as well as the rest of the Sol system. The first settlers were support personnel from UESPA who oversaw the launch and refuel operations for the various ships that were considered too dangerous to perform near Earth. By the 24th century, it had a thriving population of 100,000 residents and was home to the Mars Elective Assembly.
