Skyhook

Skyhooks are suborbital platforms anchored to a low planetary orbit. Earth and its natural satellite, Luna, house a number of military-oriented skyhook defense complexes in their orbits. Crucial to the defense of humanity's homeworld, these stations came under attack by the Covenant during the Battle of Earth in late 2552. ONI security personnel equipped with Air Assault-class armor were deployed to prevent the Covenant from gaining control of these facilities.

Judging by their description, the Forerunner gas mine over Threshold appears to resemble a skyhook in its general principle, being suspended deep in the gas giant's atmosphere by a cable attached to a high-altitude suspension grid.
