Medical Facility Endurance (Earth-5875)

Medical Facility Endurance was a space station of the Office of Naval Intelligence that orbited Reach.

History
The candidates of the SPARTAN-II Program underwent the augmentations of the SPARTAN-II Enhancement Program aboard Medical Facility Endurance in 2525, where they were observed by Dr. Catherine Halsey and Chief Petty Officer Franklin Mendez.

The surgeries ended with thirty of the candidates dead, and other twelve severely crippled. Only thirty-three were apt for combat roles.

The space station was destroyed by the Covenant during the Fall of Reach in August 2552.
