## Space Scanner

Sends a Green Signal to its automation circuit when it detects incoming objects from space. Can be configured to detect incoming meteor showers or returning space rockets.

Networks of many scanners will scan more efficiently than one on its own.

### Auto Out

**Green**: Incoming target detected
**Red**: No target detected

## Materials

### Refined Metal

25 kg

**Space Scanner** is a building that can detect incoming Meteor Showers or Rockets. It sends a Green automation signal when the target is detected, and the little screen at the bottom turns red. The Green automation signal will persist through the entirety of a meteor shower (or until the rocket has fully landed), even if the Space Scanner loses line of sight to the sky. Once the meteor shower has finished, the Space Scanner will require line of sight to the sky once again.

You can also build the scanner completely under ground, so that it never has sky access - it will be sending green signal only during the meteor shower.

Light blocking tiles within the range of space scanners decrease their **Detector Network Quality**, and can delay the detection time.

Placing multiple space scanners will make the **Detector Network** detect the meteor shower earlier.

The scanner has no overheat temperature so it won't be affected by being covered by Regolith, however it can be still damaged by meteorites hitting it.

The space scanner was significantly reworked in update 561558. Major changes include removing the restrictions on near-by industrial machinery. In addition, scanners no longer have individual listed network quality, only the shared "**Detector Network Quality"**.

## Details

    **NOTE: The following information is likely inaccurate following update 561558, in which the sky-detection systems for the space scanner, telescope, and meteor blaster were re-worked.**

* Scan Quality is affected by its view of the sky as well as nearby machines. For maximum quality, the scanner must:
	+ Have the center tile exposed to the sky (above the bottom left corner of the scanner). [+6.7%]
	+ Have 13 to 15 tiles exposed to the sky on both sides in a V shape centered on the center tile, for a total of 28 tiles. This does not include tiles above the build limit. [+3.3% Collectively for each successive tile, calculated from center and not passing any blocked tile]
		- If building on the side of the map, there is a strange behavior due to the fact that the asteroid is round - a scanner built on the very left side of the map will have its quality reduced if there is a high pile of Regolith on the very right side of the map. This is however inconsistent with industrial machinery detection - you can build two scanners on both sides of the map (at the same height) and they will both have 100% scan quality.
	+ Fit under the upper limit of the map (could fit 9 tiles between the scanner and no-build zone).
	+ NOT have its view of the sky obstructed by tiles that do not allow airflow (this includes Window Tiles).
	+ NOT have its view of the sky obstructed by certain amount of liquid or gas (mass limit varies depending on the elements; e.g. 31372 g of water or 1568 g of crude oil).
* If the center tile is blocked, Scan Quality will always result in 0%.
* Scan Quality is NOT affected by:
	+ Tiles that allow airflow (Airflow Tiles, Mesh Tiles, closed Pneumatic Doors & opened Airlocks).
	+ Any tiles under the V shape view of the scanner.
	+ Whether the scanner has the Space Exposure status or not.
* Scan Quality cannot increase above 100%, but Scan Network Quality can.
* At 0% Scan Network Quality, scanners will detect incoming objects 1s to 200s before they occur.
* At 100% Scan Network Quality or above, scanners will always detect incoming objects 200s ahead of time.
* Each scanner gives 17% Scan Network Quality at most, giving 102% with 6 scanners.
* Each percent of Network Quality adds 2 second to the floor of detection time.
* Different scanners can detect the meteor shower at different times, e.g. one could send a green signal 150 s before and the other 90 s before.

## Bugs

* Rockets will not appear on the scanner's list of objects to detect immediately and it is unclear when it actually happens. Reloading the game should resolve it.
* The scanner detecting a rocket will send a green signal for a few seconds while the rocket is launching.
