It stayed open, thats how the dawn got back. During the ceremony it wasn't on so they most likely found a way to turn it off.
The portal collapsed, the destruction of the Ark/Installation 04B destroyed the portal 'destination'. That's why the thing closed on the Dawn after the explosion. It could be said that Master Chief was responsible for the closure since he activated Installation 04B. The front half of the ship landed on Earth while the back half stayed close to the where the Ark was and drifted into space.
