Spaced Out

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

## Construction

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.

Due to game limitations, there can only be 16 active command modules at the same time.

### Engines

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.

### 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.

### 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.

  Basic Nosecone | 400 kg Refined Metal
200 kg Insulator
  Drillcone | 400 kg Refined Metal
200 kg Plastic

## Rocket Interior

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

## Launch

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).

## Landing

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.
