Rail Station

*This article is a stub. You can help Astroneer Wiki by expanding it.*

 Tier
 Crafted at

**Rail Stations** are a Railway item in Astroneer. They allow Rail Cars to stop, load, or unload their cargo, as well as calling railway vehicles to the station.

## Uses

Rail Stations are used mainly as stops for  Rail Cars and  Rail Engines, which allow for the loading and unloading of items and resources. The control panel on the station's platform allows the player to change the stop and loading modes and can call rail vehicles.

Stop mode allows the station to stop no rail vehicles, stop only uncalled rail vehicles (those automated from other locations or piloted by the player), or to stop all rail vehicles.

Loading mode allows the station to load items to storages on rail cars or unload items to storages on the station platform. When in loading mode, Rail Cars that stop at a station will have all slots filled on the cars' storage. When arriving at an unload station, all storages will be emptied from the rail cars, if enough space is available.

Rail Stations have two Target Pins and two Pin Slots, allowing for more controlled automation. Target Pins will send a signal to any connected items when a rail vehicle passes through or stops at the station. When a signal is sent to the Pin Slots, the station will send rail vehicles out the side of the station of the slot that was activated.

Attaching a Target Pin from Sensors or Repeaters directly on the station will call rail vehicles to it.

Rail Stations have a slot next to the control panel meant for a Beacon to be placed on to.
Steel

Tier

**Steel** is a composite resource in Astroneer. It is represented as a bunch of rods with a reddish-gray gradient.

## Uses

Steel is used to craft the following items:

## Trivia

* The simplified in-game production of steel most closely resembles a modern-day, real-world process that skips the production of pig iron as a separate stage.

 Size
 Day/Night Cycle
 Power

**Tundra** is one of the Planets in Astroneer.

Tundra is similar to the Terran starter planet, except much colder and hence covered in snow and ice. They can consist of flat plains and tundras or large mountains and winding hills. Wind turbines are recommended on this planet due to the naturally windy conditions, which may also cause storms to appear more frequently. Although the longer day/night cycle renders solar panels less valuable they are not a bad idea for all day power.

You need Titanite or Hematite? This is the **best planet** for that purpose. *Update 0.10.2.0*

The average time it takes for a day/night cycle to pass is around 20 minutes.

## Resources

* Common
	+ Sphalerite
	+ Laterite
	+ Hematite
	+ Wolframite
* Uncommon
	+ Titanite
	+ Resin
	+ Compound
	+ Ammonium
	+ Graphite
	+ Clay
* Rare
	+ Astronium
	+ Quartz
* Atmospheric
	+ Hydrogen (50 ppu)
	+ Helium
* Unavailable
	+ Malachite
	+ Lithium

## Biomes

* **Icy Plains**: Ice spikes occasionally form in clusters. Plenty of wind, which makes this a perfect place to plant your wind turbines.
* **The Tundra**: Small patches of organic resources may appear; lots of rocky formations.
* **Snowy Hills**: Highlands with thick layers of snow on top.
* **Acid Lake**: Doesn't actually contain acid; named due to small ponds of green-colored Terrain with red dirt forming around them.

* Icy Plains; notice the common formations of spikes
* The Tundra
* Rocky formation around a small patch of Organics
* Snowy Hills
* The Acid Lake

On this planet there are sections of short upside down cone shaped pillars, which will often have research items on the top.

## Trivia

* Tundra is the planet where Marbles can be found in abundance and the only planet where they can be found on it's surface.
Sylvie

Binomial Name
 Buff
 Favorite Food

**Sylvie** is one of the seven Galastropods in Astroneer.

## Source

Sylvie is rewarded by completing the G. sylva: Recovery mission, after providing an Empty Terrarium with  Soil,  Zinc, and a Bouncevine seed for the G. sylva: Terrarium mission.

## Uses

Sylvie provides an illumination buff for 10 minutes when fed a seed, acting like a Worklight. Feeding Sylvie a Mutant Hissbine Seed increases the buff to 30 minutes.

## Lore

The following lore may be accessed through the Data Log panel on the Xenobiology Lab.

### Galastropoda sylva // Sylvie

"A brave and curious companion who emits a bright light from their body when well fed. Sylvie illuminates the darkest of places no matter where they reside."

## Trivia

* Sylvie is the only Galastropod that is named after the planet it resides in.

Patch 189

Version Number
 Game Stage
 Official Notes
 Previous Patch

## Updates

**Implemented raw logging for join errors in multiplayer games.**

**Implemented player-facing messages for join errors in multiplayer games.**

Multiplayer joining and error logging is still a work in progress, but at the very least you can now troubleshoot when things do go wrong.

**Rover center of gravity has been lowered, improving handling.**

Rovers still have a way to go, but the center of gravity change will help them to stay a little bit lower to the ground when traversing planets.

**Thrusters are now 10x as fun as they were before.**

Thrusters are still in the experimental stage, and will likely play a much bigger role when modularity is further along (see below for more details) but for now, use their upgraded thrust at your own peril, or enjoyment ;)

**Sprint can now be toggled on the Xbox GamePad by pressing the left thumbstick.**

No more broken thumbs. This is also part of the overall control and interaction refactor on the roadmap.

## Bug Fixes

* Fixed an issue where players became stuck inside the Habitat.
Titanite

Tier

**Titanite** is a rare resource in Astroneer. It occurs in nodes of tall, cylindrical lime green crystals.

## Source

**Titanite** can be found on the following planets:

  Glacio | Cave Layers

The  Trade Platform gives 1 **Titanite** for every 2  Scrap, up to 4 total for 8  Scrap.

## Uses

Titanite is used to craft the following items:

## Media

* Titanite icon
* A single node of Titanite
* A Titanite Deposit
Medium Printer

Tier
 Crafted at
 Power Drain | 2 units of power

The **Medium Printer** is a printing module that creates Tier-3 Base related modules, such as the Research Chamber and the Large Platform A, as well as. It needs to be placed on a platform or a rover with a free Tier 2 slot to function. It will not work if placed on any storage or on any shuttle. Due to it being capable of creating essential modules such as the Research Chamber, Smelting Furnace, and the Chemistry Lab, it is arguably one of the most important objects in the game.

The **Starting** **Medium Printer** cannot be shredded in the Medium Shredder or Large Shredder, likely so players will not abuse the infinite startup packages. However, a **Medium Printer** the player has crafted can be shredded for scrap.

## Uses

The Medium Printer is used to create the following items:

### Missions

* Printing Up requires the player to print a Medium Printer and place it on a platform.

## Media

* An active Medium Printer placed on a medium platform
Seeds

**Seeds** are items that drop occasionally when digging up defensive flora. When planted, they grow into the flora of that seed type. Digging up the plants gives the same Research Samples, Research Items and seeds that naturally-occurring flora gives.

"Mutant Seeds" are harmless versions of offensive flora. These seeds can be planted, but cannot be used for Bytes in a Research Chamber. These seeds, along with the plants they germinate, have their glowing, red parts replaced by glowing, blue parts, allowing players to easily distinguish between them and their non-mutated counterparts. Mutant seeds are most useful for feeding Galastropods.

## Types of Seeds

There are two main kinds of seeds, defensive flora seeds and mutant offensive flora seeds. The mutant seeds mutate the offensive flora to just be decorative, removing the plants' ability to harm the player, while defensive flora grown from seeds may still affect the player.

### Defensive Flora Seeds

* Popcoral seed
* Bouncevine seed
* Daggeroot seed
* Wheezeweed seed
* Lashleaf seed
* Thistlewhip seed
* Spinelily seed

### Mutant Flora Seeds

* Mutant Hissbine seed
* Mutant Spiny Attactus seed
* Mutant Volatile Attactus seed
* Mutant Noxious Cataplant seed
* Mutant Volatile Cataplant seed
* Mutant Boomalloon seed
* Mutant Noxious Spewflower seed
* Mutant Elegant Spewflower seed

### Other Seeds

* Sturdysquash seed
* Knobbly Sturdysquash seed
* Plump Sturdysquash seed
* Smiling Spookysquash seed
* Stunted Spookysquash seed

## Uses

To use a **Seed** the player must place them on the ground then hold the Use key (PC: , Xbox: , PS4: , Switch: ) to plant the seed. Seeds take a couple of minutes to harvest. When ready, the player may either dig the plant up or, depending on the type, may press the Use key on the plant to harvest (or utilize Proximity Repeater for automation). Mutant flora will produce 2 seeds (with the exception of mutant Boomalloons, which produce 3 seeds), and other types of flora will produce one, with a chance of more.

## Notes

* Seeds cannot be planted on Hardness 3 Terrain, such as the terrain in the outer core of Atrox.
	+ However, they can be planted on all structures of the Gateway Fast Travel Network.
Medium Resource Canister

Tier
 Crafted at

The Medium Resource Canister is storage item in Astroneer. It allows players to store more of one resource than other storage items allow.

## Uses

* The Medium Resource Canister can hold up to 32 nuggets of a single type of resource. They cannot be used to hold Atmospheric Resources, Soil and Hydrazine, or EXO chips.

## Modes

The Player can cycle between the two modes of the Medium Resource Canister by pressing `**F**`, `**XBONE\_Y**`, or `**PS4\_Triangle**`.

### Holding Mode

When in this mode, the Medium Resource Canister will take from any available storage the resource it is holding. If it is empty, it will take the first resource it finds from such storage and start holding it.

### Dispensing Mode

When in this mode, the Medium Resource Canister will deposit to any available storage the resource it holding.

Note that the Medium Resource Canister will not grab or deposit from Printers.

## Notes

* The Medium Resource Canister was first shown off on the SES Dev Twitch stream on May 29, 2020.
* Scrap counts as a Resource and can therefore be stored in a Medium Resource Canister.
* It is possible for 34 nuggets to be stored in the Medium Resource Canister. One nugget will be placed in the input slot on top of the canister when it is full, and a second nugget may be manually placed on the output slot.
Tethers

Tier
 Crafted at

**Tethers** are an oxygen item in Astroneer that can be crafted via the backpack. They allow for players to expand their reach for early-game exploration.

## Uses

* To place a tether, press (PC: , Xbox: , PS4: , Switch: ) to drop a tether at the player's feet. The tether can then be dragged into the desired position and can cling to walls or ceilings. Note that tethers must simply be within distance of each other to connect; they do NOT need line of sight with each other.
* A tether line will be created between two tether posts that are close enough. When dragging a tether, a transparent dotted line will show to which tether the new one will be connected to when released (if any).
* Tether lines will be blue when connected to an oxygen source or dashed blue/yellow when power is also flowing toward a player.
* When the tethers are not connected to any base or vehicle that has an oxygenator attached to it, the tether lines will be black. In that case, the player won't get oxygen or power from them.
* Vehicles can link to tethers when an oxygenator is placed on the vehicle. They will act as a source of oxygen only, unless the vehicle has a power source. If the player runs out of power while tethered to a vehicle, the vehicle's internal power will begin to feed to the player without recharging their equipment.
* Only the player can recharge their power through a tether. Vehicles and bases will not receive power. However, one can charge a  Small Battery and then place it onto the vehicle/base that needs power.
* Once placed, tethers can be picked up again and put back in a tether stack (or empty slot, thereby creating a tether stack) by clicking on the stack in the backpack. Using (PC:  + , Xbox:  + , PS4:  + , Switch:  + ) on a tether while holding it will automatically return it to the backpack, assuming there is space for it.

### Missions

* Breathing Space requires the player to print a Tether Bundle and connect a tether to an oxygen supply.

## Media

* Tether Icon
* A single Tether
Methane

Tier

**Methane** is an atmospheric resource in Astroneer. It is a dark turquoise gas that is stored in a spherical canister. A teal ring on top indicates how much gas is left in the canister.

## Source

**Methane** can be found on the following planets using the  Atmospheric Condenser:

 Novus : 75 ppu
 Atrox : 100 ppu
## Uses

**Methane** is used to craft the following items:

## Notes

* Methane will explode either when Dynamite is set off nearby or when placed in an active Smelting Furnace.
Medium Platform A

Tier
 Crafted at

**Medium Platform A** is one of the main building modules of Astroneer.

## Notes

* One Tier-2 Attachment Slot.
	+ 8 Tier-1 modules can be stored by using 1x  Medium Storage while 24 Tier-1 modules can be stored by using 1x  Medium Storage Silo.
* Four Power connection slots that can be used to connect to your base.
* Can connect to  Tethers to provide Oxygen and Power to the player if an  Oxygenator is connected through the network.
* Can be attached to walls and ceilings.
Site Pylon

*This article is a stub. You can help Astroneer Wiki by expanding it.*

 Tier

**Site Pylons** are a railway item in Astroneer. They allow for the creation of rail lines, and can be used to recall Rail Engines to the Site Pylon. They spawn on Glacio and Calidor near mission items.

## Source

Site Pylons spawn on Glacio and Calidor near mission items, such as Freight Modules, Frozen Argon, Artifacts, and Obelisks.

## Uses

Site Pylons will connect rail lines to any other pylon, Rail Post, Tall Rail Post, or Rail Junction. They are best used with Junctions, as the Site Pylons are a dead-end.

Site Pylons may be picked up and moved for better placement of rails. The Packager can be used on it for better transportation.
Odd Stone

Information below contains information that may ruin your enjoyment of discovering the game's secrets for yourself. Proceed at your own risk.

 *Spoiler Warning: Information below contains information that may ruin your enjoyment of discovering the game's secrets for yourself. Proceed at your own risk.*

The **Odd Stone** is an interactable object that appears after activating Gateway Engines or a Gateway Chamber. Interacting with it allows the player to utilize the Gateway Fast Travel Network.

When a Gateway Chamber is powered, the Odd Stone will appear in the center, allowing the player to interact with it. Once two chambers are active, the player may teleport between them at any time. This allows for faster travel across the planets.

When the player activates the Gateway Engine in the center of a planet using the Geometric Triptych of that planet, the odd stone will appear, allowing the player to then travel to the Gateway Portal satellite after first flying there in a shuttle.

## Notes

* Each node on the odd stone corresponds to different locations on the planet. Each planet has a north, south, and four equator nodes, while the two moons only have two equator nodes.
* A Dim Node is a chamber that has not yet been activated, while a Bright Node is an active chamber available to be teleported to. The Bright Node with a white sphere indicates the player's current chamber location.
* A now-patched glitch caused the player to die unexpectedly after attempting to activate the Gateway Fast Travel Network.

## Media

* Odd Stone on Sylva with Retro Astroneer for scale.
* Retro Astroneer about to gaze upon the Odd Stone.
Modules

**Modules** are a type of item in Astroneer that allows players to advance in the game by crafting resources, providing bytes, or cleaning up debris found on the planets. They vary in size, from medium to extra large, and need to be placed on the proper Attachment Slot to function.

Modules are available early on, having all Printers available at the very start, and with the Research Chamber as the first a player should unlock. From there, they are available at different points of the game to further progression and add more gameplay. All modules can be unlocked in the Research Catalog, and cost Bytes to unlock them.

## Notes

* While the printers are listed as items in their descriptions, they have the same functions as modules, as they craft all other items in the game.
* Every crafting module, those with interfaces, have a button that allows you to loop the crafting process as long as you have the resources on you.
Small Canister

Tier
 Crafted at

The **Small Canister** is an tool item that is used to store Soil.

## Uses

Small Canisters are used to hold  Soil. Players and vehicles that have empty canisters will gather soil until they are filled. Filled soil canisters can be used to terraform the terrain or used in the  Soil Centrifuge to obtain universal Resources.

When  Hydrazine is created, it is already inside of a canister, and once used up the canister disappears.

### Missions

* Landfilling requires the player to attach a Small Canister to the backpack or Terrain Tool and fill it with soil.
* A Small Canister full of soil is required for the following missions: G. sylva: Terrarium, G. desolo: Terrarium, G. calidor: Terrarium, G. novus: Terrarium, G. vesania: Terrarium, G. glacio: Terrarium and G. atrox: Terrarium.

## Notes

* The canister has an indicator on its top face which previews how much material is inside. When empty, the surface is black. When partially full, the surface has a colored indicator showing the percentage of material inside, and the light on top changes to bright orange. When full, the light changes to green and the indicator becomes a full circle.
* When a canister is equipped, the terrain tool's reticle displays a circle indicating the amount of soil the player has available. Equipping more than one canister will divide the circle into parts based on how many canisters the player is using.

## Media

* Different Indicator of Canister
* Small Canister full of Soil
Rail Post

*This article is a stub. You can help Astroneer Wiki by expanding it.*

 Tier

The **Rail Post** is a railway item in Astroneer. It allows for the creation of rail lines, and can be used to recall Rail Engines to it. It can also be used as an “extended Extender”, being able to channel power and O2 between bases. It has 2 small slots which can be useful for putting a Worklight with Power Sensor in it.

## Source

Rail Posts are placed from a  Rail Post Bundle.

## Uses

Placing a Rail Post within range of another will connect a rail line between them, deforming any terrain that might be in the way.

Rail Posts may be placed on any terrain, allowing for placement on walls and ceilings of caves.

The maximum placement distance for the post is shown as a coloured dial on the base of the post when placing.

* White indicates valid placement, below the maximum rail length.
* Blue indicates valid placement at optimal rail length.
* Pink indicates invalid placement -- whether from being placed too far, too close, or from creating too sharp of a turn.
Medium Platform C

Tier
 Crafted at

**Medium Platform C** is a circular variant of the Medium Platform A in Astroneer.

## Notes

* One Tier-2 Attachment Slot.
	+ 8 Tier-1 modules can be stored by using 1x  Medium Storage while 24 Tier-1 modules can be stored by using 1x  Medium Storage Silo.
* Three Power connection slots that can be used to connect to your base.
* Can connect to  Tethers to provide Oxygen and Power to the player if an  Oxygenator is connected through the network.
* Can be attached to walls and ceilings.
Power Cells

Tier
 Crafted at

**Power Cells** are a consumable power storage item. Once crafted, they provide power to whatever they are attached to. Once all 8 cells are depleted, the Power Cells will be destroyed.

## Uses

* Power Throughput Rate: 1 U/s
* Power Capacity: 48 U
* Power Cells will fill one bar of a Small Battery in 4 seconds.
* Power Cells contain 1.5x as much Power as a Small Battery.
* Power Cells cannot be recharged, and instead evaporate once depleted.

## Trivia

* Power Cells discharge to the player's backpack automatically if it isn't already full.
* Due to their small size and relatively high energy density, a single Power Cell can fuel a  Buggy for 42 minutes. They aren't useless on Medium Rovers, either being able to power them for 96 seconds or 1 minute 36 seconds using only **one** power cell

Medium Storage Silo

Tier
 Crafted at

**Medium Storage Silo** is a utility item that can carry up to 24 Tier-1 items.

## Uses

* They can store up to 24 Tier-1 items.
* Medium Storage Silos take up the same amount of space as a  Medium Storage while being able to store 3 times as much.
* The cost of a Medium Storage Silo makes it more efficient as a late-game storage solution.

## See Also

* Large Storage Silo A
* Large Storage Silo B
Tiers

**Tiers** are used to categorize all items in Astroneer. Tiers exist based on whether the item fits in a certain attachment slot or based on which Printer the item is crafted from, such as Titanium and a stack of Tethers being Tier 1, or Research Items and Medium Wind Turbines being Tier 2. Items that are in Crates, such as freshly printed items or those packed with a Packager, are considered one tier lower than when they are unpacked. For instance, a packed Medium Printer (Tier 2) fits in a Tier 1 attachment slot, and a packed Extra Large Shredder (Tier 4) fits in a Tier 3 attachment slot.

## Tier 1 - Small

Tier 1 refers to any small-sized item. Items in this category fit into a single slot and can be dragged around easily. These items are small enough to be stored in the Backpack, and include Resources or any item crafted in the Backpack Printer. A select few items can also be printed in the Small Printer. Some items, such as the Small Solar Panel, spawn a Small Platform when placed on the ground. This allows the item to be used without it being placed in an attachment slot.

## Tier 2 - Medium

Tier 2 refers to any medium-sized item. Items in this category fit onto a 2-slot connection and must be placed on a platform if they require power to function. This tier includes all Research Items as well as all items that can only be crafted with a Small Printer, e.g., the Medium Storage. These items cannot be placed in the backpack, but the player may instead carry one of them by selecting the item and dragging it into their hands or by pressing the Use key (PC: , Xbox: , PS4: , Switch: ). Holding the item will slow the player down until they drop the item. Medium items may be packaged with a Packager so they may be placed in the backpack.

## Tier 3 - Large

Tier 3 refers to any large-sized item. Items in this category fit onto a 4-slot connection and must be placed on a platform if they require power to function. These items cannot be easily carried, and the player moves much slower when holding them. Packaging these items with a Packager makes them Tier 2, allowing easier transport. Items in this tier include Research Chamber, Medium Rover, and any other item crafted at the Medium Printer.

## Tier 4 - Extra Large

Tier 4 refers to extra large-sized items. Items in this category fit onto an 8-slot connection and modules must be placed on a platform if they require power to function. These items are hardest to move, making the player stand still when being held, requiring being in a Crate to allow the player to move. This tier includes Large Rovers, Shuttles, and any other item made in the Large Printer. Tier-4 items can’t be shredded and need to be blown up with Dynamite to be broken down into shreddable debris.

## Trivia

* In SES Vlog 23, a Rover with an unreleased tier of Attachment Slot was shown, which looked like a fifth tier. This never actually made it into the game, and was described as a "wild exploration".

## Media

* Tier Slots on a Medium Platform B, a Large Platform A, and an Extra Large Platform A.
* Unreleased tier of Attachment Slot shown in SES Vlog 23.
Tall Rail Post Bundle

*This article is a stub. You can help Astroneer Wiki by expanding it.*

 Tier
 Crafted at

**Tall Rail Post Bundles** are a railway item in Astroneer. They are a bundle of 10 Tall Rail Posts.

## Uses

Tall Rail Post Bundles are used to place  Tall Rail Posts on terrain to expand the rail lines. The bundles may be placed in the Backpack's aux slots, which allows for quicker placement by pressing the context keys (PC:  or ).
Shredders

*This article is a stub. You can help Astroneer Wiki by expanding it.*

Shredders are items in Astroneer that allow the player to destroy unwanted items or Debris and turn them into  Scrap. They vary in size, allowing for bigger items to be shredded using the larger shredders. Shredders are the best way to obtain Scrap in Adventure mode, and Scrap is a useful resource as it can be traded for other resources via the Trade Platform.

## Types of Shredders

* Medium Shredder: The Medium Shredder is the smallest shredder. It can be placed on any Tier 2 slot, but will only shred Tier 1 items. It draws a maximum of 5 U/s power while shredding something.
* Large Shredder: The Large Shredder is the mid-sized shredder, and is placed on any Tier 3 slot. It is able to shred items Tier 2 or smaller, drawing up to 7.5 U/s power while doing so. The input area has the same placement rules as a normal Tier 2 slot, meaning you can place multiple smaller items in it.
* Extra Large Shredder: The Extra Large Shredder is the largest shredder, being placed on any Tier 4 slot. It is able to shred items of Tier 3 or smaller, and while shredding it draws up to 10 U/s power. The input area has the same placement rules as a standard Tier 3 slot, so you can put several smaller items in it.

## Notes

* Dynamite can be used to reduce larger items to multiple smaller items. This includes Tier 4 items which are unable to be shredded without the use of Dynamite.
* Dynamite itself cannot be shredded. If you place it in an active shredder it will blow up, destroying the shredder and the platform it was attached to.
* Shredders consume less total power when the input U/s is below the max.
* Other items that cannot be shredded include Resources, Packaged items, Vehicles, and Tier 4 items, though the latter two can be reduced with Dynamite.
* A Shredder can be placed on a Rover, allowing a player to collect Scrap without having to take debris back to their base.
* It is possible to recover some items that are being shredded by using a Packager on the Shredder, popping the item off unharmed. Debris items and bundles will be destroyed.

## Updates

### Research System now uses Multi-Phase rates

This release we've made a big update to the research system that debuted in our last update. Now every research subject contains multiple phases with different Byte values. Some items have their most valuable phase early, some much later, and some in between. So if you really want to maximize your research operations, you have lots of new decisions to make about what to research, when, and for how long. To help you make these decisions and figure out how much you want to min-max as a player, the Control Panel on the Research Chamber now shows a timeline of all the current item's phases.

If your current research subject has moved into a lower-rate phase, and want to replace it something that's higher value, you can stop the current research operation and and load in the new subject right away. But be careful, stopping a research operation early means sacrificing any uncollected points! So don't be reckless, okay?

### Update to the lighting system has been implemented

In this patch we included an overhaul to the lighting system. The main goal was to get the game running using the ACES tone mapper, so we could then get the game running in HDR in a future update. That meant spending lots of time recreating the look of Astroneer in a completely new system. We aren't completely done tweaking this, but overall this approach is a huge step in the right direction.

## Bug Fixes

* Fixed a number of issues that were causing save files to be deleted when the game crashed or the application was closed. In the most common case, this occurred when very large saves took enough time to write out that the user had time to close the window before the file finished.
* Fixed an issue causing inconsistent playback of Gas Hazard audio
* Fixed a minor issue where the Astroneer could still walk around when scrolling through the pages of the Help screen.
* Fixed an annoying Multiplayer bug which prevented the Client player from exiting a flipped vehicle in Multiplayer games.
* By adjusting a few things in the engineering team’s favorite part of the code, local wind effects should now only spawn for the relevant player rather than all players in a Multiplayer game.
* Fixed a bug where the Research platform remained in the "completed" state if it lost power while in that state.
* Base platforms no longer have "ghost" slots on the front that store only Compound. Goodbye, secret Compound storage.

Oxygen (resource)

This page is kept for historical purposes.

 *The subject of this article has been removed from the game in an update.*

*For the mechanic, see Oxygen.*

 Tier

**Oxygen** is a resource that is consumed constantly by the player, produced endlessly by habitats and vehicles, can be found naturally and also stored in stacks.

Much like Power, Oxygen is commonly found on the surface of planets, as well as inside caves, in the form of blue deposits (outcropping from the ground). It was found, prior to 0.4.10221.0, in spires.

When harvested from the environment, oxygen will stack up on the back of the deform tool which will then be transferred to the backpack once the stack is complete. An oxygen stack can then be moved and placed on any storage slot. As oxygen is consumed from the stack it will shrink and, once it's completely consumed, the stack will disappear.

A full stack holds 35 seconds of oxygen, or the equivalent of half a tank.

When they are present in the backpack, oxygen stacks do not replenish tanks but they will be consumed after them (as of 0.2.115.0). On the other hand, mining oxygen from patches will replenish tanks before stacking oxygen in the deform tool.

## Media

* A Patch of oxygen crystals
* A spire of oxygen. These were removed as of 0.4.10221.0.

Narrow Mod

Tier
 Type
 Crafted at

The **Narrow Mod** is a Terrain Tool augment that makes the terraforming diameter smaller and decreases the deform speed, allowing the player to terraform and paint Terrain with more precision.

If both the Wide Mod and **Narrow Mod** are attached to the Terrain Tool, the mod closest to the top of the tool will take priority over the other.

* This mod can be combined with other mods such as the Inhibitor Mod and Terrain Analyzer to produce effects.
* This mod will not work with the Wide Mod.
* Stacking this augment has no additional effect.
* This mod was tweaked slower for use with the Leveling Block to more easily create structures.

Solid-Fuel Thruster

Tier
 Crafted at

The **Solid-Fuel Thruster** is a Tier 2 vehicle attachment. They are expendable, with enough charges allowing a maximum of four take-offs and planet hops, requiring more packed thrusters in the backpack should the player wish to go on longer trips.

## Usage

**Solid-Fuel Thrusters** can be attached to any vehicle or structure with a Tier-2 slot available. They are best used with the Small Shuttle early on as a way to explore other planets before acquiring the Hydrazine Thruster, Medium Shuttle and Large Shuttle. They can be used up to 4 times, with take-offs and moving to another planet each consuming one use, while landing consumes none. Once the thruster is used up, it turns into debris that may be shredded. The four uses allow the player to travel to one planet and back to their home base, but requiring more thrusters to visit other planets before returning.

Solid-Fuel Thrusters may also be placed on Rovers and activated to boost the rover and possibly launch it into the sky. Doing so may result in the rover getting stuck due to the way physics works in the game.

The Solid-Fuel Thruster may be shredded for 1.5 scrap, whether it is unused or fully burnt out.

## Notes

* The cost of the Solid-Fuel Thruster is 2 scrap (1 for the ammonium and 1 for the aluminum) and the spent thruster is worth 1.5 scrap, for a total loss of 0.5 scrap per thruster. 0.5/4 = 0.125 scrap per use. This means that it is more cost-effective than Hydrazine Thrusters which costs 2 scrap (2 ammonium) for 8 uses, 2/8 = 0.25 scrap per use.
* Using a Packager on a partially used Solid-Fuel Thruster will refresh the thruster to a freshly printed state.
Small Generator

Tier
 Crafted at

The **Small Generator** is a power generation item in Astroneer that produces power by consuming  Organic. It can be used from the widget slots on a player's backpack, on any regular attachment slot, or on the ground. Once a nugget of  Organic is placed in its input slot, the generator will convert the Organic to Power over time.

The Small Generator may be turned on and off to save the nugget for when power is needed.

## Uses

* Power Production Rate: 2 U/s
* Small Generator will fill one bar of battery in 2 seconds.
* One  Organic will fuel the Small Generator for 120 seconds and produces 240 Units.

This generator can be placed in either a Widget slot on a player's backpack, on a platform, or on the ground. Once a nugget of  Organic is placed on top of it, the generator will convert the Organic to Power over time.

The Small Generator can be turned on and off by hovering over it and pressing the Use key (PC: , Xbox: , PS4: , Switch: ). Organic won't be consumed when turned off.

Power output may be automated by placing the Small Generator on a platform with storages attached that contain  Organic. When one nugget has been used up, the next will be pulled until all nuggets have been used up, at which point the generator will stop producing power.

### Missions

* Powerful Problems requires the player to print and connect a Small Generator to a power network.

## Notes

* When placed on the ground, a Small Platform appears underneath the generator, allowing for two power cables to be connected.

## Trivia

In the Excavation Update, the Small Generator swapped places with the Small Solar Panel, specifically as a power management tutorial.

In the Basebuilding Update, the generator can now be toggled on or off, saving fuel. It also creates a small platform under it when placed on the ground.

Power Sensor

Tier
 Crafted at

The **Power Sensor** is an Automation item in Astroneer. It allows players to detect when there is a change in power flow and will send a signal to connected items.

## Uses

The Power Sensor can be used to detect when there are changes in the flow of power to the connected platform, such as losing or gaining power. This can be useful to shut down or start parts of players' bases when the state of solar and wind changes. This can also be useful to detect when power shuts down and trigger Generators to turn on to provide extra power at nighttime.

Power Sensors currently have three different settings, which are indicated by the green arrows on its side. The player can cycle through those by pressing the Use key (PC: , Xbox: , PS4: , Switch: ). Each sending a signal when a state change is detected:

* Gained or Lost: Will send a signal when power is gained or lost. It must first lose power before being able to detect power gain again.
* Gained: Will send a signal each time that power is gained.
* Lost: Will send a signal each time that power is lost.

### Example

The images above show a simple example how to wire up a  **Power Sensor** located in the background. It is connected via network cable to the  Small Wind Turbine on the left. The Power Sensor has its pin connected to a  Small Generator on the right and is set on Gained-Or-Lost-Mode. At the first time, the player has to manually turn on the generator, while the wind turbine is off. The network cable on the right provides power to the rest of the network.

After this, it works automatically: The generator turns off, when wind energy is available (left image), and turns on, when no wind blows (right image). Of course, the player has to provide new fuel for the generator e.g. by using an  Auto Arm or connecting it to a  Medium Resource Canister.

The  Extender in the center was not yet mentioned, but is crucial for the setup to work: It allows the Power only to flow in the shown direction. Otherwise, power from the generator (or the network) would flow back through the wind turbine into the sensor and turn the generator off immediately, resulting in turning it on and off in fast succession.
Medium Solar Panel

Tier
 Crafted at

The **Medium Solar Panel** is a power generation item.

It only produces power when exposed to sunlight. The two panels are folded upward over the center when it is not exposed to sunlight. The Medium Solar Panel doesn't have any power output cables, therefore must be placed on a Platform with 2-slot connection in order to get produced power.

## Uses

* A Medium Solar Panel will fill one column of a medium battery in 4 seconds.
* A Medium Solar Panel produces four times as much power as a  Small Solar Panel.

## Media

* Solar Power Icon
* A Small Solar Panel and a **Solar Panel** for comparison
* Solar Panel on its Pre-Release version.
* A closed up Medium Solar.

## Trivia

* The Pre-Release version had a similarity to pathfinder from the movie "The Martian". It has 3 panels, which were changed to 2 along with a new model later in Pre-Alpha.

## Updates

### Exotic Moon Tech Test

**This build includes a first look at an early version of Exotic Moon.** We are using it as a stress test for Terrain 2.0, the new technology we are using to generate planets. This planet is an earlier unfinished version than the current development one, so it will be missing large parts of the gameplay loop. You should expect to encounter bugs and missing gameplay. If you do, please report them on our forums so we can track major issues as we go through our bugfix phase before 1.0! No amount of feedback is too small! You can access the build by scrolling left on the starting menu space ship and loading "Terrain Tech Test"

Because the planet has missing decorators, effects, research, and resources, Exo Dynamics has provided the Astroneer with 100k bytes, and an experimental development plinth that provides all necessary resources to craft items. Consider this an EXTREMELY loose test for players who want "Creative Mode" type experience. Please give us feedback on what you would like to see included if Astroneer added a dedicated creative experience after 1.0!

Also, the planet has a fixed seed, so every player of the game will experience the same exact planet. Share your favorite mountains, caves, craters, and with others and directions on how to get there using the Astroneer's compass!

### "Retro" Suit Unlock

**As a gift to everyone who supported us throughout development, a new suit has been added to the game!** This “Retro” suit is exclusively for Early Access and Game Preview players of Astroneer as a thanks for your ideas, bug reports, feedback, and encouragement. Anyone who owns the game before 1.0 will receive the "Retro" suit, and we have no plans for making it available to post 1.0 players. Thanks so much for your support thus far!

## Bug Fixes

The following live issues have been fixed as of version 0.10.5.0:

* Addressed an issue where some players were unable to join a Multiplayer game on Xbox One. We will keep monitoring to see if the issue persists, please let us know on the forums if you are still encountering this problem.
* Fixed a bug where clicking on the opened Backpack while holding down a terrain modifier key breaks cursor selection
* Fixed a Multiplayer bug where Client players could not start the Soil Centrifuge from the control panel
* Fixed a bug where the Chemistry Lab would stop functioning mid-print if a player was holding enough resources to perform crafting twice
* 3-Seat modules should now be appropriately facing outward when printing directly on an Extra Large Rover.
* Fixed a rare, but annoying crash that occurred when players attempted to shred a second non-empty Oxygen tank with oxygen in it after shredding a non-empty Oxygen tank.

Small Platform

*This article is a stub. You can help Astroneer Wiki by expanding it.*

 Tier
 Type

Small Platforms appear when the player drops a Widget on the ground, and disappear after the Widget is picked up again. It has 2 cable plugs, and like other platforms, they can stick to walls or ceilings. Small platforms are only big enough to hold the respective Widget that was used to spawn it, with no space for additional resources.

## Small Platform Widgets

The following items all use a Small Platform when placed on the ground:

* Worklight
* Floodlight
* QT-RTG
* Small Generator
* Small Wind Turbine
* Small Solar Panel
* Small Battery
* Small Printer
* Power Switch

## Bugs

* When the Small Platform is removed and still has a Power cable plugged in, the cable will start to recede into the platform, which is no longer there, making the cable plug shake for a second before it starts to disappear.
