Basics

Juno: New Origins at it's core is a sandbox rocket and aviation simulator where players can build their own rockets, which is the main point of the game - build a rocket to explore the solar system, complete contracts and more.

## Structural

A command pod is used for command purposes, which include taking control of and attitude control. A command pod can be a capsule, command chip, or command disc. A command chip is light, but has no batteries or gyros, but that can allow players to make creative capsules.

A fuel tank is used to store fuel or for structural purposes. They can have many different types of fuels.

## Fuel

Fuel is used in almost all engines, and some types can only be used on certain parts.

The most common fuels are kerolox, hydrolox, and methalox. They are used in most rocket engines.

### Aspects

Kerolox is heavier and less efficient but requires smaller tanks for the same burn time. Hydrolox is lighter and much more efficient but requires larger tanks for the same burn time, while methalox is in-between. These fuels are used in Liquid engines.

Solid is heavy but produces large thrust and is used in Solid engines.

Liquid hydrogen is light and extremely efficient but requires huge tanks for the same burn time. Water on the other hand is less efficient but requires much smaller tanks for the same burn time. These fuels are used by Nuclear Thermal engines.

Monopropellant is used in Monopropellant engines.

## Rockets

*Main article: Rocket Engine*
Rockets are powered by a rocket engine, which can be found under the Propulsion tab. There are many default engines, but they all can be customized interchangeably.

### Engine Types

When selecting a rocket engine and going to the "Properties" tab, multiple settings can be seen. One of them is the engine type. Liquid engines have throttle control and general thrust. Solid engines are powerful but have a set throttling that cannot be changed. Nuclear Thermal engines are very efficient, but have very slow throttle response and thrust. Lastly, Monopropellant engines are very low thrust, but are good for deep-space maneuvers.

### Power Cycle (liquid engines)

The power cycle selector can have a great impact on the performance of the engine. The cycles are more powerful in the following order: Pressure Fed > Electric > Gas Generator 1 > Gas Generator 2 > Staged > Full Flow Staged. However, electric requires batteries, which are heavy.

### Fuel Selector (liquid and nuclear thermal)

The fuel selector simply changes the type of fuel the engine uses. Look at Fuel for more details.

### Chamber Pressure

Higher values increase thrust and efficiency, but degrades performance in a vacuum.

### Gimbal Range

The gimbal range dictates how much the engine can move to assist in attitude control.

### Nozzle

The selector determines what nozzle style to use, which can impact performance. Most players use the "Bell" nozzle.

### Nozzle Throat Size

This slider determines the size of the nozzle throat. Higher values increase thrust but decrease vacuum efficiency.

### Nozzle Length (certain Nozzle settings only)

This slider determines the length of the nozzle. Higher values increase efficiency in a vacuum but can decrease thrust and efficiency in atmospheres.

### Symmetry

Symmetry can easily allow a player to attach multiple engines on rockets, from 1 ~ 6.
