Docking Hub Alpha is a room on Norion. It appears in Metroid Prime 3: Corruption. This is where Samus Aran first arrives on Norion during the Space Pirate invasion.


This room consists of two major areas: an outer area in which the forest world of Norion can be seen, and an inner area which provides further access to Base Sector Zero. There is a central platform, with two Mk XII "Hydra" Multiturrets guarding the east and west sides of the platform. In the northwest is an entrance to a secluded area. Further along is a gap over which there is a Missile Expansion, though there is a Grapple Point which can be used to traverse this gap. On the southeast corner of the central platform, a couple of stacked crates and one lone crate, while at the southwest corner are two lone crates. On the south end is a door which seals off the Galactic Federation base from the outside; this door can be opened from the outside by firing weapons at four different targets on the face of the door. Inside the entrance to the base is another door which can be opened by another weapons-sensitive target, which reveals the entrance to inside an enclosed room containing the lore "Planet Norion", and more importantly, the Grapple Lasso. Moving through the first corridor, there is a console which can be scanned to reveal a security lever. Operating it will allow access to an elevator that will take passengers up to the entrance to the next room, the Hub Access.


Samus observes the battle from the Hub.

Samus Aran arrives here in the midst of the Pirate attack on Norion. Base Sector Zero on Norion is under heavy fire, and the battle does not appear to be going well. Samus docks her Gunship on the landing platform, where a Federation Marine (internally named "Trooper 002") guides her into landing her ship. He then alerts her to the situation at the base: the Space Pirates have managed to knock out all three of the base's energy generators. She and the other hunters must re-activate the generators. The Federation Marine will then move to the side and stand by the Gunship for the time being. She can then head towards the south entrance to the base; while doing so, a Space Pirate Boarding Pod will dive in and bombard the west rail cannons with weapons fire, destroying it. She then opens up the entrance to the base, and she may then activate the elevator to enter the base, though it is more convenient for her to open the door to the Grapple Lasso upgrade and acquire it so as to save time. After doing so, she can ride the elevator up into the base and enter Hub Access.

After initializing her Command Visor and re-activating Generator A, she can then go here as an alternative to running through the Pirate-infiltrated Conduit A. When the Pirate attack is finally repelled, an additional Federation Marine will have been stationed near the main elevator entrance to welcome Samus back. Additionally, after acquiring the Grapple Swing, she may then land here to acquire the Missile Expansion in the room.

If the game is saved here after landing and restarted later, the Marine that initially briefs Samus will be gone.

Federation Marine dialogue[]

During invasion:

Stand to, Samus.

Our situation doesn't look good. The pirate attack has knocked out our generators and disabled the planetary-defense system.

This cannon was our only weapon capable of taking out orbiting ships.

We need you and the other Hunters to get the generators back online and restore power to the cannon so we can repulse this assault.

I'm uploading the generator coordinates to you now. Good hunting.

We need to get those generators back online, Samus. [if spoken to afterward]

After invasion (possibly different Marine):

Welcome back, Samus. We are in the middle of major repairs due to the pirate attack, so excuse the mess.
