Science, sometimes called science points, is needed to unlock new parts in the technology tree when playing in the Career or Science modes (Sandbox starts with all parts unlocked). Science is obtained by performing different scientific activities in different situations and biomes (where available), then either returning to Kerbin or transmitting the activity data home with an antenna. Science may also be obtained as a reward for the performance of various contracts, or gained through the implementation of administrative strategies. Experiments can be removed from the parts they were performed in and are stored with a Kerbal on EVA. Additionally, science experiments can be stored in and retrieved from any part that Kerbals can ride in, although only one copy of an experiment for any specific situation (ex. EVA report flying over Kerbin's shores) can be stored per Kerbal-carrying part.

Situations

Situations reflect the flight status of the craft or kerbonaut relative to a celestial body. There are six possible situations, some of which may be irrelevant to a given science activity or unavailable on a given celestial body.

• SrfLanded: in contact with the terrestrial surface
• SrfSplashed: in a liquid body on the surface (such as oceans)
• Flying Low: above the surface at any height, if and only if an atmosphere is present
• Flying High: in the upper atmosphere, if and only if an atmosphere is present
• In Space Low: above the surface at any height and not in an atmosphere
• In Space High: high above the surface and any atmosphere but still in its SOI

An atmosphere is required for the situations "Flying Low" and "Flying High" and the Sensor Array Computing Nose Cone. As of KSP version 1.0.2, the PresMat Barometer can be used without an atmosphere. If soaring through an upper or lower atmosphere on a trajectory to an escape from the planet or moon's sphere of influence, the situation is assigned as "In Space Low" regardless of the presence of the atmosphere. The situation will only change to "Flying High" or "Flying Low" if/when the aerodynamic forces cause an orbit to be captured during the encounter.

Biomes

Biomes are areas of a body's surface specially mapped in KSP game data. Each additional biome grants a separate set of opportunities to do Science Activities, provided the Activity is biome-dependent in the given Situation. Each planet with solid surface and each moon has biomes, because of this several biomes have to be visited with landers or rovers for total research of the given celestial body.

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(SOI) have no effect on the Science Points that can be earned doing science activities within the SOI of any other celestial body.

Possible combinations of Activity, Situation, and Biome

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 for a given Situation and, if so, whether it differs by Biome or gives one Global result for the entire celestial body.

Activities and situations requiring an atmosphere are italicized and colored.

Crew

The following Activities are performed by Kerbals during an EVA or from within a crewed command module.

Surface Sample

Requires	One kerbonaut
Data size	30 Mits
Base value	30
Maximum value	40
Data scale	1
Transmission efficiency	25%
Processing energy	300 ⚡

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 situation (landed or splashed) just as with craft. In Career mode, Surface Samples cannot be taken without having the Research and Development Facility upgraded to its second level.

EVA Report

Requires	One kerbonaut
Data size	8 Mits
Base value	8
Maximum value	8
Data scale	1
Transmission efficiency	100%
Processing energy	80 ⚡

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/situation combination is necessary. The easiest ways to take a Flying Low report are to jump from the surface, or hang onto a ladder whilst landed.

A kerbonaut can only take and hold one EVA Report at a time without storing it in a Command Pod, though reports retrieved from a Command Pod have no limitations on how many of a type can be carried.

Asteroid Sample

Requires	One kerbonaut One Asteroid
Data size	60 Mits
Base value	60
Maximum value	70
Data scale	1
Transmission efficiency	30%
Processing energy	600 ⚡

Asteroid Samples can be taken by kerbonauts when performing an EVA close to an asteroid. The samples give various results depending on the altitude of the orbiting planet.

Crew Report

Requires	A manned command pod
Data size	5 Mits
Base value	5
Maximum value	5
Data scale	1
Transmission efficiency	100%
Processing energy	50 ⚡

Crew Reports can be created in any manned command pod. Reports uniquely differ between celestial body and situation. Because the transmission efficiency is 100%, repeating them or transmitting them multiple times yields no additional Science.

If a command pod has taken a Crew Report but not transmitted it, it cannot take a new report even when in a new situation, biome, or sphere of influence. This limitation can be circumvented by having a kerbonaut on EVA "take data" from the command pod. Even if they store the data in the same command pod it was taken from, the Crew Report will be treated as just another piece of data to store. A second Crew Report can be taken even in exactly the same spot; no additional points are yielded by duplicate Crew Reports though.

Modules

Experiments done by separate parts like the Mystery Goo™ Containment Unit behave similarly to Crew Reports. They may be performed in different flight phases and on different celestial bodies returning different results. Each module 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. Data can also be extracted from the module by a kerbonaut during an EVA. There is a penalty for transmitting data home instead of recovering the module to Kerbin.

Since version 0.23, transmitting or collecting data renders the Mystery Goo™ Containment Unit and SC-9001 Science Jr. disabled for the remainder of a flight. If the craft has (or can be docked with) a fully crewed lab, it can reset those modules at a cost of time and electric charge. Since version 1.0, these modules can also be reset by a scientist on EVA, allowing a craft with a scientist on board to collect multiple results (from different situations and biomes) on a single mission, without needing a full lab as part of the craft. The results collected and stored during a mission can be transferred to a lab at the end of the mission (or taken back to Kerbin).

Processing energy (⚡)	100	250	80	120	500	600	2000

The transmission efficiency caps the maximum returnable science with the experiment via antennae. To gather all scientific value experiments needs to be recovered. With the release of 1.0, transmission efficiency drops radically on experiments that have already been performed and transmitted. If an experiment is recovered, transmission efficiency for that experiment drops to zero (situation and biome specific).

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).

Celestial body multipliers

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.

Contracts

As of 0.24, players can access various contracts at Mission Control while playing in career mode. The rewards for accomplishing contracts vary and can include a significant amount of Science.

Administrative Strategies

The various strategies that can be implemented at the Administration Facility while playing in career mode also have a significant effect on science income. Each strategy is based on trading one "resource" (reputation, funds, or science) for another as each is earned. Thus, at the cost of reputation or funds, the player can boost their science income. Conversely, the player can spend science to boost one of the other two resources. For example, the strategy "Outsourced R&D" yields science at the cost of funds, while "Open-Source Tech Program" will take a fraction of the player's science every time it is earned and convert it to reputation. Anywhere from 5% to 100% of the income from any of the resources can be converted into one of the others.

Science Archives

The Science Archive

A filterable list of the experiments which have been performed so far can be accessed through the “Science Archive” tab in the Research and Development window.

The entries show what data have been brought back and whether more data from repeating activities can be gather. If the bar below an experiment is not completely full, as shown in some of the examples on the right, the experiment can be repeated to gain additional science. This is also useful to see what biomes and situations haven't been covered yet and provide the richest opportunities are.
