Ivanoff Station

Ivanoff Station is a UNSC orbital research facility stationed in an asteroid field near Installation 03. It was built after the Office of Naval Intelligence discovered the location of the Installation after the end of the Human-Covenant War.

History
In March 2553, Dr. Catherine Halsey was indefinitely detained here by Admiral Margaret Parangosky, as retribution for lying to her about the creation and deployment of flash clones during the SPARTAN-II Program's early phases. Catherine Halsey was later allowed to work on the, and although she was to be transferred back to the station after finishing, she was still working aboard the ship by 2558.

The main purpose of the facility was to study the ancient Forerunner artifact known as the Composer, embedded inside the asteroid the station was built into. Searching for the Composer after being revived on Requiem, the Didact traveled to the station and attacked it with Covenant forces loyal to him. Despite the efforts of the Master Chief who had hitched a ride on a Lich, the Didact succeeded in getting the Composer and fired it at Ivanoff Station, digitizing everyone except the Master Chief who had an immunity to the weapon activated in him earlier by the Librarian. With everyone in the station dead and the Didact leaving, the Master Chief abandoned the station in one of its F-41 Broadsword fighters armed with one of the station's excavation-grade HAVOK tactical nuclear weapons in hopes of stopping the Didact from doing the same to Earth.

The station also contained objects removed from Installation 03, including the ring's activation index.
