The Stellosphere is a spaceship that appears in the Disney Junior animated series, Miles from Tomorrowland. Crewed by the Callisto family and commanded by Miles' mother, Captain Phoebe Callisto, the Stellosphere's mission is to explore and connect the universe for the Tomorrowland Transit Authority.



Stella is the ship's main computer who assists and watches over the Callisto family throughout their daily lives aboard the ship. Her mainframe is located in the main power access room. From there she can operate, as well fly the Stellosphere entirely alone. But her primary duty is assistance and security. Throughout the ship, the Stellosphere is fitted with Voice Modulators which allows Stella to speak to anyone from any part of the ship. Set on the walls, her modulators are black wide monitors that display two white dots and a straight line that flashes vertical bars each time she makes a sound.

Despite being a computer that follows orders, Stella is capable of thinking for herself and offer suggestions without being asked. She is shown to have a calm, friendly, nurturing personality and overtime the Callistos have come to see Stella as a member of the family.


  • Ship Security: The Stellosphere's computer, Stella, was once fitted with a new security programmed to capture any intruders who may try to invade or steal the ship. When on guard, Stella's voice modulators would turn red. If there were any intruders present, Stella would first scan the area. Once an intruder was detected and showed resistance, Stella would launch holographic bolas to capture them. However, the security module fitted into Stella's mainframe was discovered to be defective and caused her to malfunction the following day. It was removed soon after.
The update of the Stellosphere

The Stellosphere in Galactech Mode.

  • Galactech Mode: When the Stellosphere suffered severe damage after passing through a portal that led to the Builder's homeworld, the ship was upgraded with a powerful energy globe known as Galactech, making the Stellosphere the fastest and most advanced starship in the TTA. When in Galactech mode, the Stellosphere becomes more faster and stronger than it usually is. It even changes appearance when in this state, along with everything else on board, like the Callisto's spacesuits. The Galactech can also self repair any damage to the Stellosphere, leaving it looking like new.
    • Galactech Shields: When in very intense conditions, the Galactech shields are strong enough to withstand any harsh environments the Stellosphere encounters, such as the intense weather conditions of a Hot Jupiter. Once activated, the ship becomes covered from nose to tail in holographic armor.


  • Bridge - Located at the front of the ship is the command center (often known as the bridge), which provides all command and control functions operated by three duty stations (including the helm), one each for Miles, Loretta and Leo. The captain's command station is located in the center of the bridge, behind the helm station. Three holoscreen monitors can be displayed in front or behind Phoebe's command chair whenever she needs to use the computer systems.
  • Main Hangar - Located at the front of the ship on the lower decks is the ship's main hangar bay, where the Callisto's alternative transportation is kept and where other ships dock. Among the vehicles used by the Callistos, one shuttlecraft is known as the Star Jetter serves as their main transportation on their missions and the other is a two passenger vessel known as the Photon Flyer.
  • Mess Hall - The mess hall is the Callisto's dining room and kitchen where the family come to sit and have their daily meals or just relax and unwind the day's care.
  • Holo Course - A training simulation arena located on the ship, that replicates a typical mission environment using realistic holographic projections. The course is often used for Exo-Suit training.
  • Workshop - Located near the main hangar, the workshop is where Leo Callisto repairs and invents things.
  • Bio Garden - The Bio Garden is a arboretum garden located at the top back of the Stellosphere, housing many kinds of flowers and trees. It is often a place where the Callistos can relax or grow things in a natural setting.
  • Main Power Access Room - The Main Power Access Room is where the ship's main computer system "Stella" is located.
  • Οbservation Deck - Located at the top front of the Stellosphere.

  • Stella, the ship's computer voice is provided by Grey DeLisle.
  • The bridge layout shares some similarities to the starship bridges from the Star Trek franchise, the command chair in the centre and surrounded by several computer conceals and the helm at the front. However, unlike the command chairs in Star Trek, Captain Phoebe can have a holoscreen conceal displayed in front of her chair.
    • The design of the command chair shares a couple of resemblances to the Enterprise command chair seen in J. J. Abrams' Star Trek.
