Human-Covenant war
Prior 2552, an operation on Ballast took place, where the ODST Gretchen Ketola lost her leg when she stepped an Insurrectionist landmine.

During the Human-Covenant War, the world was attacked by the Covenant. During the course of the battle, it is rumored that the UNSC Defense Force succeeded in defeating the Covenant, although it is possible that the rumor was created by the Office of Naval Intelligence to raise morale. The colony was apparently still intact during the Battle for Earth, as evidenced by active transports from the colony to the Quito Space Tether.

Post-war
After the war, as part of Project ALOHA-19, an Acheron Security A.I. memory matrix containment and display module was shipped from Havenwinter on Ballast to UNSC Transit Dock L22 on Luna, and from there to an Outpost Discovery on Earth.

Economy
The car manufacturing company Kabord was originally based out of Vallejo, a city on the world,

Trivia
On the Halo 3 multiplayer map Orbital, one of the incoming transports is from Ballast.
