Each space object in FrontierSpace represents one 'hull' within the simulation. Multiple hulls can be attached together ('linked'). A single linked set of hulls is the basic object on which the simulation operates.
Each hull has a given number of mount points, each of which may contain a space component. Any hull can have any number of space devices associated with it, as well. Additionally, each hull should have an associated space zone object.
A space object is simply a normal object of type 'thing' with the Space_Object flag set and the following attributes:
| Attribute | Description |
|---|---|
| ZONE | the dbref of the space zone for the hull |
| COORDINATES | the full coordinates of the hull's current location |
| BEARING | the direction the hull is facing in the X/Y plane |
| MARK | the direction the hull is facing out of the X/Y plane |
| DESIRED_BEARING | the direction the hull is turning to in the X/Y plane |
| DESIRED_MARK | the direction the hull is turning to out of the X/Y plane |
| WARP_FACTOR | the speed of the hull if at warp |
| MOVEMENT_VELOCITY | the current speed of the hull |
| INTEGRITY | the number of 'hit points' the hull has |
| MAX_INTEGRITY | the maximum value for INTEGRITY |
| RADIUS | the radius of the hull |
| MASS | the mass of the hull |
| CAN_LAND | a boolean value telling whether the hull can land |
| CAN_LAUNCH | whether the hull can take off after landing |
| HATCH | 0 for closed, 1 for open |
| AIRLOCK | the dbref of the hull's airlock |
| DOCKED_AT | the dbref of the object the hull is docked at |
| AIRLOCK_ARC | an arc within which the airlock faces |
| LINK_POINTS | a list of link points, see 'Space Link Points' |
| DOCKING_PORTS | a list of docking ports |
| DOCKING_ARC | an arc within which the docking ports face |
| DOCKING_DOOR | the status of the docking door |
| DOCKING_DOOR_TIME | how many seconds the door takes to transition |
| DOCKING_DOOR_TIME_REMAINING | seconds until the door is done moving |
| MOUNT_POINTS | a list of mount points, see 'Space Mount Points' |
| DEVICES | a list of space devices |
| REPAIR_CREWS | a list of repair crews |

| AUNLINKED | triggered on female object when two hulls are unlinked%0 = link point number%1 = dbref of male hull%2 = link point on male hull |
| ADOCK | triggered when the hull docks at another hull%0 = dbref of hull it is docking to%1 = docking port number |
| ADOCKEDAT | triggered when another hull docks at this one%0 = docking port number%1 = dbref of the hull docking there |
| AUNDOCK | triggered when the hull undocks from another hull%0 = dbref of hull it is undocking from%1 = docking port number |
| AUNDOCKEDFROM | triggered when another hull undocks from this one%0 = docking port number%1 = dbref of the hull undocking from there |
| ADOOROPEN | triggered when the docking door is fully opened |
| ADOORCLOSE | triggered when the docking door is fully closed |
| AENTERWARP | triggered when the hull goes to warp |
| ALEAVEWARP | triggered when the hull drops out of warp |
