We can't send a rescue ship all the way out there, so Aurora, you're just gonna have to meet us halfway.

The Neptune Escape Rocket is a vehicle that is used to leave Planet 4546B. It consists of five constructable parts: the Neptune Launch Platform, the Neptune Gantry, Neptune Ion Boosters, Neptune Fuel Reserve, and Neptune Cockpit. The Neptune Launch Platform can be built using the Mobile Vehicle Bay, while the other four components are built on the launch platform.

The Neptune Escape Rocket cannot be launched unless the Quarantine Enforcement Platform is disabled. Attempting to do so will result in the PDA informing the player that the base needs to be disabled.



The Player can find the blueprints for the Neptune Launch Platform inside the Captain's Quarters of the Aurora. The door will be locked, but can be accessed using the entry code, which is 2679. Accessing the data entry will unlock the Blueprints.

Neptune Launch Platform

The Neptune Launch Platform is a very large floating barge with ladders on each side. In the middle is a circular indentation where the rocket will sit. On one side is a terminal used to construct the individual rocket segments, and can be used to rename and recolor the rocket once it has been fully completed. The terminal possesses fabrication drones similar to the Mobile Vehicle Bay.

Neptune Gantry

The Neptune Gantry is the second component of the Neptune Rocket. It consists of a small metal pillar with a bridge (which eventually leads into the Neptune Rocket) and an elevator which can lift the player to the top of the gantry to access the cockpit.

Neptune Ion Boosters

The 1st stage of the Neptune Rocket consists of a cylindrical shape with launching clamps connected to it. This portion consists of the thrusters, and serves no personal function other than to progress to the other stage.

Neptune Fuel Reserve

The 2nd stage adds more to the body of the rocket, including the hatch that leads inside, where the player can find a ladder leading up to the cockpit, as well as lockers surrounding the central column. Three levers can be found in this section as well, and it is required to pull them in order to launch. The engine is housed here as well.

Neptune Cockpit

The 3rd and final stage represents the main cockpit of the Neptune Rocket. Here the player can access the Time Capsule launcher, main CPU, life support systems, and the command chair which will initiate the launch to escape Planet 4546B.

Once the Neptune Escape Rocket has been completed, the player can "say farewell" to their Cuddlefish.[1]

The Time Capsule can be placed in a slot, and can be edited to include various items, a picture, and a message to be found by other players. The Time Capsule will be jettisoned upon the Rocket's launch.

Data Bank Entry


This blueprint set was developed at Alterra headquarters specifically to get you off 4546B and back to the nearest phasegate. It takes into account local gravity, astronomical data and available resources, and is piloted by AI. It may be adapted to employ whatever power source is available - but it will require a lot of it.

It consists of five independently constructible elements:

  • Launch Platform: Floating platform provides a solid base from which to launch the rocket
  • Gantry: Provides structural support
  • Stage 1: Primary thrusters for reaching atmosphere escape velocity
  • Stage 2: Secondary thrusters activated in orbit
  • Stage 3: Cockpit


  • One-person life support
  • Short-range communications
  • Adaptable power supply
  • Orbital shielding
  • Onboard time capsule

Warning: Onboard AI will not launch if local threats are detected.

Warning: The use of alien materials to power the craft may increase its range in unpredictable ways.


  • The Neptune Launch Platform would originally require Ion Cube Matrix in order to craft the Neptune Fuel Reserve. This was later changed in version 1.0, with the craft using Ion Power Cells instead.
