Rockets in the Spaced Out DLC are multi-component constructs used to explore starmap, and send duplicants and cargo to different planetoids.


A Rocket Platform is the mandatory building on which a rocket is assembled. Modules are added in its menu once they have been researched.

A rocket requires at least a command module, an engine (with oxidizer possibly) and a nosecone. Engines are always placed at the bottom and nosecones at the top. Additional modules can be built such as cargo to transport goods and rover modules to visit planetoids; they don't have specific order and they can be reorder without deconstruction.


Engines limit how high a rocket can be constructed. Each module has a burdening factor that weighs down the rocket, thus slowing its speed (tiles/cycle it travels). Rocket speed = Engine Power divided by total Burden. Neither burden nor weight affect rocket range, only the amount of burnable fuel available.

* While it can take more fuel, it's not possible to have enough Oxidizer for that much fuel.

** This is only possible with Liquid Oxygen.

Fuel tanks and Oxidizers[]

Sugar, Petroleum and Hydrogen-propulsed rockets require oxidizer at a ratio of 1:1 per kg of fuel when using Fertilizer, 1:2 when using Oxylite, and 1:4 when using Liquid Oxygen.

Module Material Burden Height Storage Capacity
Large Liquid Fuel Tank Large Liquid Fuel Tank 100 kg Steel 5 5 900 kg
Small Solid Oxidizer Tank (Spaced Out) Small Solid Oxidizer Tank 200 kg Metal Ore 2 2 450 kg
Large Solid Oxidizer Tank Large Solid Oxidizer Tank 100 kg Steel 5 5 900 kg
Liquid Oxidizer Tank (Spaced Out) Liquid Oxidizer Tank 100 kg Steel 5 2 450 kg

Cargo Modules[]

Cargo carry goods from or to asteroids, or fulfill any survival needs of the command capsule. Each module features an external port that corresponds to their specific resource, which is unlocked via the same research as the module variant. This port must be in direct contact with either the rocket platform or another port. Fittings carry anything from a cargo module into the command capsule.

Utility Modules[]

Utility modules are used to better explore and colonize asteroids or make rockets command modules livable longer.

Module Material Burden Height Description
Orbital Cargo Module (Spaced Out) Orbital Cargo Module 400 kg Metal Ore 4 2 Delivers cargo to the surface of Planetoids in several small packages which totals to up to 6000 kg.
Rover Module (Spaced Out) Rover Module 200 kg Metal Ore 4 3 Deploys a Rover Bot for remote Planetoid exploration.
Trailblazer Module (Spaced Out) Trailblazer Module 200 kg Refined Metal 4 3 Enables landing for one Duplicant to Planetoids that do not yet have a Rocket Platform.
Cartographic Module Cartographic Module 350 kg Steel
1000 kg Plastic
3 5 Automatically analyzes adjacent space while on a voyage (this is instant for Planetoids) thus enables moving to unrevealed space.
Battery Module Battery Module 400 kg Metal Ore 2 2 Stores 100 kJ of power and leaks 400 J per cycle, while producing no heat. It thus acts as a superior version of the Jumbo Battery.
Solar Panel Module Solar Panel Module 200 kg Glass 1 1 Produces 60 W when there is sunlight, which can be used with the power outlet fitting to power equipment inside the rocket.
Artifact Transport Module Artifact Transport Module 200 kg Refined Metal 6 1 Collects and transports Artifacts from Space POI.

Command Modules and Nosecones[]

Command modules are required for the rocket to function and only one can be part of any rocket. Solo Spacefarer Nosecone can only be build at the top of the rocket while Spacefarer Module can be build anywhere but takes an extra Basic Nosecone or Drillcone.

Module Material Burden Height
Solo Spacefarer Nosecone (Spaced Out) Solo Spacefarer Nosecone 200 kg Metal Ore 3 3
Spacefarer Module (Spaced Out) Spacefarer Module 200 kg Metal Ore 6 4
Basic Nosecone (Spaced Out) Basic Nosecone 400 kg Refined Metal

Rocket Interior[]

Interior of a Solo Spacefarer Nosecone

Solo Spacefarer Nosecone functions as both the command module and nosecone, and totalizes 28 empty tiles. Spacefarer Module offers a bigger 10x8 interior to be furnished, but does not serve as a nosecone.


In order for the rocket to launch, the command module checks for various conditions:

  • A destination must be set.
  • The rocket cannot have any pending constructions (it can be launched if a lander is not constructed).
  • A rocket must have an engine and nosecone.
  • A rocket must have a fuel tank (most engines have a fuel tank included).
  • Cannot be over rocket engine height limit.
  • The rocket must be sufficiently fueled to reach the destination (it can be launched even if there is not enough fuel to return).
  • Cargo transfer must be complete (rocket can still be launched with partially filled cargo).
  • Skilled crew must be onboard (crew is set through the pop-up and no other passengers is aboard).


A rocket cannot land on a planetoid that does not possess a Rocket Platform. If so, a duplicant must be first sent via the Teleporter Transmitter or in a Trailblazer to the surface in order to construct one. In the event that multiple rocket platforms are available, the rocket will default to selecting one randomly; alternatively, the player can specify the platform to land on.

Heat and Exhaust[]

All rockets project a large amount of heat onto all cells from the bottom of the engine; the area of projection is a 3x9 rectangle from the exhaust (3x7 from below the Rocket Platform); this includes cells past walls beneath the platform.

Any cells within this area will be superheated, including gases emitted by the engines themselves; the exact amount of heat is unclear, though the following has been observed:

  • Carbon Dioxide emissions from Petroleum-using engines can reach above 1500 °C with a density up to 6.0 kg per tile.
  • Squares with 80 to 100 g of Oxygen (made thin by being vented into regions next to the void of space) can reach more than 2000 °C, suggesting that the projection is a flat heat output instead of heat transfer from a hotter object.
