Samus Aran receives a Baby's Cry distress signal and lands her Gunship here. Upon exiting her ship, Samus starts to explore, until she spots the Galactic Federation Military Transport Hygieia to her left, occupying what would have been her landing station. She is surprised to find that the Galactic Federation is here, and hears an explosion farther off. She continues on into the station to find the 07th Platoon, and the source of the explosions being their attempts at opening a Red Blast Shield, that Samus easily breaks through with a Missile.
After landing, Samus is unable to return to her starship conventionally, but by following a Morph Ball passage to a high ledge overlooking the Spaceport, she can enter the Cargo Hold and from there re-enter the Spaceport and reach her ship. She later returns to her ship with Anthony Higgs and Madeline Bergman after her assistance in the defeat of MB, and leaves the BOTTLE SHIP, only to return a few days later. She again lands in her initial landing pod, despite the fact that the Galactic Federation had taken the Hygieia ship back to headquarters, thus leaving the main pod open to land on. The last time the Spaceport is seen is when Samus returns to her ship, following the securing of Adam's helmet.
- Missile Tank
- Hidden on a ledge inaccessible through this room. Samus must progress on through the Main Sector until she reaches a room that connects to a restroom, and features a ruined conference desk. After destroying an obstruction in the wall, Samus can roll through a tunnel in Morph Ball form to reach the ledge with the Missile Tank. A terminal here allows Samus to unlock a door off the ledge, as she cannot jump down to the area with her ship.
- Despite what it may seem, Samus can recharge and save at her gunship. She can do so if she returns to her gunship through the Cargo Hold or after returning to the BOTTLE SHIP.
- Returning to her ship was also impractical for Samus during her extermination of the Metroids in Metroid II: Return of Samus. The only way she was able to return to it was through extensive backtracking, or simply returning with the baby.
