Science, sometimes called science points, is needed to unlock new parts in the technology tree. It is obtained by performing different scientific activities at different locations and then either returning to Kerbin and recovering the craft or sending the scientific analysis home through an antenna.

Science activities

This is an overview of all science activities which can be performed and how results differ by biome and situation. Activities performed within one Sphere of Influence have no effect on the Science Points that can be earned doing science activities within the SOI of any other celestial body.

Biomes are areas of a body's surface defined by an additional map in KSP game data. Experiments may have different results when performed in different biomes; this means more opportunities for fresh Science Points. Currently[outdated] only the planet Kerbin and its moons, Mun and Minmus, are fully detailed with biomes; Eve and Laythe have simply "land" and "ocean" biomes.
Some combinations of activity and situation ignore biomes and give the same result wherever performed within an SOI; these combinations are marked " Global " in the table below.

Situations reflect whether your craft or Kerbonaut is on the ground (landed), in a body of water (splashed), or in one of four possible flight conditions within the SOI a celestial body.
An atmosphere is required for the situations Flying Low and Flying High and for using the PresMat Barometer and the Sensor Array Computing Nose Cone. Also, KSP only considers a craft (or Kerbal) to be in an atmospheric region if it is on a sub-orbital trajectory. For example, taking readings while aerobraking in the upper atmosphere will return data for the In Space Low situation instead of Flying High even if the altitude is below the edge of space.

Table of science activities and situations

The top row of the chart names each activity; the left hand column shows the six possible situations. Each intersection shows whether the activity is possible and, if so, whether it differs by biome or gives one result globally for the entire celestial body for a given situation. Activities and situations requiring an atmosphere are highlighted.

Crew Report

Requires A manned command pod
Base value 5
Maximum value 5
Data scale 1
Transmission efficiency 100%

Crew Reports can be created in every manned command pod. Each command pod can only store one report at a time (Kerbonauts seem to be unable to memorize more than one at a time), but they can be sent home with an antenna without penalty allowing the crew to create a new one.

Reports differ between current celestial body, altitude, and at low altitudes also between different biomes. Only two crew reports per biome are necessary (one while landed, one while splashed) and additional reports won't yield any more results. Because the transmission efficiency is also 100% one can do multiple reports without having to fly back.

EVA Report

Requires One kerbonaut
Base value 8
Maximum value 8
Data scale 1
Transmission efficiency 100%

EVA Reports are done by kerbonauts on an EVA. Like crew reports they give different results depending on altitude and biome (if performed low enough). Only one EVA report per biome/altitude combination is necessary, although another one can be created when swimming in a biome. The easiest ways to take a low atmosphere reading are to jump from the surface, or hanging onto a ladder whilst landed.

In contrast to crew reports and experiments, a Kerbonaut can memorize a different report for each condition he performed an EVA in during the mission.

Surface Sample

Requires One kerbonaut
Base value 30
Maximum value 40
Data scale 1
Transmission efficiency 25%
Processing bonus +12%
Processing energy 300 E

Surface Samples can be taken by kerbonauts when performing an EVA on the ground or in water of a celestial body. The results vary by biome and are different while swimming within the biome too.

Experiments

Experiments are done by separate parts like the Mystery Goo™ Containment Unit and behave similar to crew reports. They may be performed in different flight phases and on different celestial bodies returning different results. Just like crew reports, each experiment part can only store one result at a time, but a result can be sent home with an antenna to allow the experiment to be performed again under the same or under new conditions. There is a penalty for sending it home instead of recovering the performed experiment. Since 0.23, transmitting data renders the Mystery Goo™ Containment Unit and SC-9001 Science Jr. disabled, so only one experiment per module can be obtained during single mission. A crewed lab can reset those parts which takes a certain amount of time. The results of an experiment can be taken out by a kerbonaut on EVA and stored in a command pod for example. Like transmitting it will disable the Mystery Goo™ Containment Unit and SC-9001 Science Jr.

The transmission efficiency caps the maximum returnable science with the experiment via antennae. To gather all scientific value experiments needs to be recovered.

Mobile Processing Lab MPL-LG-2

The Mobile Processing Lab MPL-LG-2 improves the value of science data before transmitting it; it has no effect on data kept aboard. Crew Reports and EVA Reports have no penalty on transmitting them, so lab processing doesn't benefit these two. For others, it can squeeze out points from reports that at first have "+0.0 Science" value to transmit. It can also clean the Mystery Goo™ Containment Unit and SC-9001 Science Jr. to reuse them after transmitting or collecting data.

Both cleaning and processing required a certain amount of time and electric charge. Cleaning an experiment requires the same amount of energy as processing its report data.

Craft recovery

Recovering a craft after it landed on Kerbin also yields science points by itself. Its value depends on how far the craft flew. Recovering a craft after a suborbital flight returns less valuable (but different) results than one which orbited the Mun, for example. The returned value appears to be 5 * (surfaces visited + bodies orbited).

  1. Many of these altitudes are taken from users reporting on the forum and not from game data itself.

Each celestial body has different multipliers applied to the collected scientific data, based upon where it is taken in relation to that body. Biomes do not affect these multipliers.

The altitudes given in this table determine the altitude above mean sea level of the boundary between lower and upper atmosphere and between near and outer space. The upper atmosphere extends to the atmospheric height and the outer space extends up to the end of the sphere of influence.

Getting science to Kerbin

To get the science to the Research and Development facility the report has to be in a part which stores it or transmitted with an antenna. The reports can be stored in the instruments they were created in, collected into an EVA suit or stored in a command pod. The command pod does not have to have a kerbonaut in it to store reports, but it must be capable of holding a kerbonaut. Probe cores can not store reports. It is possible to exchange reports between EVA suits and command pods freely but reports can only be collected from instruments. While on EVA, right click on an instrument or command pod and select "Take Data" to pick up a report. To save a report in a command pod, right click and select "Store Experiments" or have the kerbonaut board the command pod. A command pod can only hold one report of the same type and location at a time, although an EVA suit can hold multiple reports of the same type and situation. This can lead to extracting multiple reports on EVA which then needs to be destroyed except one when the kerbonaut wants to enter the capsule. After touch down on Kerbin the parts or kerbonauts can be recovered and the full scientific value gets added. Unlike transmission of science reports, there is no penalty for moving the report from an instrument to a command pod or from one command pod to another.

The other possibility is to transmit scientific reports back. This is possible at any time after creation. Usually there is a maximum value which can be transmitted listed as “transmission efficiency”, except for the crew and EVA report which have no penalty. With a lab it is possible to increase that efficiency. Some instruments are also locked after transmitting requiring a lab to clean them for reusability. Antennae don't require a line-of-sight to Kerbin and can be pointed in any direction to transmit. No data will be lost while transmission, and the current situation doesn't change the efficiency.
