Modules

Modules are one of the main categories of physical, interactive objects in Astroneer. Modules include all functional and attachable objects that help the player and perform some function. Some modules must be built on a platform or a vehicle, and not all modules are available from the beginning. To unlock new modules, players have to perform research. Some objects, like tethers, function differently from a module, because they do not require attachment slots in order to function. Those are called Deployables.

Tier 1

Widgets

Widgets are Small modules that can be carried in the backpack and generally have some manner of active behavior when plugged into a widget-compatible slot. Some widgets can only function if they are placed in one of the backpack's Widget Slots, like the shoulders or on the Terrain Tool.

Function with the Widget slot

• Small Solar Panels: Generates power in direct sunlight at 0.5A.
• Small Wind Turbine:Generates power depending on location and wind, at 0.5A.

Function on any slot

• Small Battery: Batteries store 2 Columns, or 8 Bars of power.
• Small Oxygen Tank: Stores Oxygen automatically, effectively expanding the oxygen reserve.
• Power Cells: Generates 12 Bars of power before disappearing completely.
• Oxygen Filters: Provides extra oxygen for a limited amount of time.
• Small Generator: The Generator consumes Organic material to produce a constant 1.0A of power. Can be activated or deactivated as necessary by hovering over and holding F.
• Portable Oxygenator: Creates oxygen at the cost of energy (a full tank will consume 10 bars of power, all the power the backpack can hold).
• Worklight: Generates light with no power cost.

• Oxygen Filters
• Tether

Augments

Augments are a category for modules that alter the function of any modules they are attached to, such as the Terrain Tool.

The Terrain Tool can have up to 3 augmentations active at one time. This can be done by attaching augments to the Terrain Tool itself. Any active augments attached to the tool will consume additional power.

List of Augments

• Inhibitor Mod: Prevents the Terrain Tool from having any net effect on Terrain, with the added side effect of permitting it to collect ore plants and materials directly off of the surface without cutting into the soil.
• Boost Mod: Increases the speed of the Terrain Tool.
• Narrow Mod: Reduces the terraforming radius.
• Wide Mod: Increases the terraforming radius.
• Alignment Mod: Creates a flat plane that is perpendicular or tangent to the curve of the planet depending on the direction you are looking.
• Terrain Analyzer: Stores Terrain color, and can be used later to paint the terrain with the stored color once the augment's gauge has been filled. Can also be used to Deform/Terraform a set color without affecting other terrain colors. (Example, if using an Analyzer that is filled with "snow" on terrain that is Not "snow", the terrain will not be removed.)
• Drill Mods - 1 - 2 - 3: Each successive drill mod level allows the player to deform harder terrain with their terrain tool, including resources within that terrain. If the current drill mod level is not sufficient, the terrain will deform very slowly and sparks will appear around the deformed area, indicating to the player that they need a higher level of drill mod.
