By 2371 a Harelian mining operation was underway, due to its rich sources of vionium.
During its initial shakedown cruise, the USS Lionheart arrived at the moon after intercepting an encoded transmission from its surface. When communications could not be established, an away team went to the surface in the shuttle Yellowjacket. ("Shakedown Cruise")
The USS Morningstar would later take a Starfleet Intelligence team to secure the mining operation.
