Mombasa Tether



"The Mombasa space elevator!" "It collapsed when the city got glassed." "But the tower was thousands of kilometers high..." "Yeah, but now it's scattered all over the savannah."

- Two Marines discussing the fate of the Space Elevator.

The New Mombasa Orbital Elevator was a Space Elevator located at the heart of the East African Protectorate city of New Mombasa on Earth. It was used for lifting heavy ordnance from the surrounding port facilities into an orbital station at the top of the elevator structure, a transport method much cheaper and more efficient than booster rockets filled with expensive fuel.

History
In the dawn of the 24th century, Mombasa was chosen to be the Earth's first tether city. As a cheap gateway to space, the elevator is the key to New Mombasa's economic and strategic importance. The presence of the elevator radically changed the structure of the city - service roads and a Mag-lev line radiate out from its base, connecting it to nearby warehouses and factories. The elevator's base resides on an artificial island full of warehouses and docking facilities, to provide more docking space for incoming cargo vessels. And it was this influx of business and trade brought in by the elevator that made New Mombasa the metropolis it was by the time of the Covenant invasion.

During the First Battle of Mombasa, the Prophet of Regret's Flagship initiated Slispace transition over the city, right beside the Orbital Elevator. The resulting shockwave swept through the structure, yet causing only minor damage. However, it collapsed by other means some time later on the same day. Eventually only a small portion of the lower support structure remained intact, even though heavily damaged. A large portion of the tower's debris was scattered around Earth's surface.

Halo 2
In Halo 2, the space elevator is visible throughout all the Earth levels, first as a thin line on the horizon in Outskirts, then later as a ringed tower in the skyline of Metropolis. Only at the end of that level is the player offered an unobstructed view of the structure from across the artificial canal.

At the end of the campaign level Metropolis, the flagship of the Prophet of Regret flees into slipspace with the In Amber Clad in hot pursuit. This in-atmosphere jump unleashes a wave of energy that scours the area. Originally this was thought to collapse the tower, but as seen in Halo 3: ODST, this wasn't the case.

Halo 3


The elevator was not seen again until the Halo 3 Announcement Trailer, in which several of its stabilizer rings lay shattered in the background hills. Concept art from the Halo 3 Zune confirmed that the wreckage of the space elevator would play an important part in the design of the Earth levels.

The elevator did make an appearance in the final game, with the player fighting through its ruins throughout Tsavo Highway and even hearing some dialogs concerning its fate from Marine allies.

Halo 3: ODST
In Halo 3: ODST, the Space Elevator's base is located on an artificial island west of the city center, with MagLev Train lines leading to it, instead of the center of the Mombasa island in Halo 2. Its general appearance has also been changed, with a less massive base structure and an additional support structure in the lower part of the tether.
