Io Station was a United Nations Space Command military platform, in orbit around Io, the third largest moon of Jupiter.
It picked up a communications fragment (located near Io) from the Prophet of Regret's fleet before it arrived in the Sol system.
It contacted John-117 on the Forerunner dreadnought before the Spartan contacted Cairo Station on Earth during the Battle of Earth.
