The Mobile Processing Lab MPL-LG-2 generates Science from experimental results, stores unlimited experiments, and allows reuse of the Mystery Goo™ Containment Unit and SC-9001 Science Jr. after transmitting or removing the results of observations.

The lab has a maximum occupancy of two Kerbals. The lab must be crewed by at least one scientist in order to process the results of science activities into "data". Once the lab contains data, the data can be slowly "researched" into science by the scientists in the lab. While processing data into science, the module consumes a lot of electricity.

The lab is not a command module; any craft it's a part of will need a probe body or command pod to be piloted. It starts unmanned by default, but crew members can be added in the Crew tab before launch. The Lab provides portraits and IVA as of the 1.0 update (but the portrait camera bounces around a lot).

The lab has two exit hatches. When brought from the part menu in VAB it defaults to orientation with the hatch used for EVA facing the left side of the lab (when looking towards the launchpad from VAB). That's the opposite orientation than default on the cargo bay modules, so if you're going to shield the lab with an MK3 cargo bay, you must first rotate it 180 degrees, or any attempt to leave it would result in a message "Hatch obstructed". Both hatches can be used to board the lab from EVA. If the lab is part of a plane then the EVA hatch defaults to facing down, which can also obstruct the hatch - again requiring a 180 degree rotation. (Note: the orientation was changed several times in 1.1, so this paragraph may be outdated.)

The Lab is quite fragile, only withstanding impacts up to 6 m/s. So if you are landing one on some celestial body, do it gently.


Experiment Storage

Even with no crew, the lab module can store unlimited amounts of "raw" experiment results (like a Kerbonaut can). In contrast, any command pod or crew module may only store one copy of each unique experiment.

Generating Science over time

Normally "data" means "results from scientific instruments or crew activities". Those must be called "experiments" here, because it is important to understand that the word "data" when used in the lab means something different. Experiments are "processed" in the lab module into a special thing that this module calls "data" (doing this uses up the experiment). Any experiment stored anywhere on a vessel with a lab can be used to produce data. Each unique experiment can produce data for a given lab module only once, but the same experiment can be taken to another lab and processed again. Multiple labs on a single vessel don't function as expected as of 1.0.2, so it is recommended that each lab be on a unique vessel. Note that after any experiment has been used to generate data, it can still be transmitted or recovered for its usual science yield. The reverse is also true; any experiment that has already been recovered at KSC for full value can still be run again, stored in the lab, and converted to the full amount of lab data in each new lab.

If one or more scientists are in a lab that contains data, then the lab may be used to perform research - which will consume a small percentage of the processed data every day to produce (as of 1.1.1) 5 times that amount of data in science. This process drains a significant amount of electric charge while active. The rate at which the data is converted into science is determined by the amount of stored data, the number of scientists in the lab, and their respective levels. The process continues in the background even when the vessel with the lab is not in focus. Up to 500 units of science can be stored before the results must be manually transmitted back to KSC, but it is necessary to regularly switch focus to the lab and transmit all that saved science. If the buffer storage of science fills up, work stops until transmission. A lab can be recovered on Kerbin to claim the science, or the science can be transmitted to KSC with an antenna.

To generate data, right-click the lab or pod where the experiments are stored and select Review Data, then select the Process Data option until the lab's data capacity is full. At this point those experiment results can be removed, they are no longer needed to process the data or generate science in the lab.

Data Value

An experimental result is processed into an amount of data based on its own original science value and the physical location of the lab at the time the data is generated. A lab on the surface of a body produces more data per experiment than one in orbit, and if the experiment is from the same body as the one the lab is orbiting or landed on the data value is greater. The exception to this is Kerbin. A lab landed on Kerbin produces much less data than one in orbit over Kerbin. (In fact, it is so much less that a lab on the surface of Kerbin is basically worthless.)

The lab can store 750 units of data. Once the buffer of data is full, the lab will refuse to process any more experiments until some of that data has been used up (by scientists doing research).

Data Processing and Research Cost

As of version 1.1, experiments are processed into data instantly, and there is no electricity used to do it anymore.

Researching data into science costs 5 units of electricity per second no matter how many scientists are participating.

Data Processing Rate

While the lab is active, the data stored in it is slowly converted into usable science. The amount of science converted per day is proportional to the amount of data stored in the lab. Only scientists in the lab contribute to research. The higher a scientist's level, the more research that scientist contributes. The data conversion rate supplied by each level of a given scientist are as follows:

Level Multiplier Rate (Percentage/Day)
☆☆☆☆☆ 1x 0.0135%
★☆☆☆☆ 5x 0.0675%
★★☆☆☆ 9x 0.1215%
★★★☆☆ 13x 0.1755%
★★★★☆ 17x 0.2295%
★★★★★ 21x 0.2835%


Once their science has been either taken or transmitted, the Mystery Goo™ Containment Unit and SC-9001 Science Jr. modules can be reset for reuse by cleaning out these experiments. This can be done in bulk for any such experiments docked to the lab, and saves the trouble of sending a scientist on EVA to manually reset the experiments.

Product description

No longer are you limited to research facilities only on Kerbin! With the Mobile Processing Lab, you can conduct long-term experiments and ongoing research with the data you collect in the field. Be sure to check back on your scientists from time to time, and transmit the results of their research home! This model is guaranteed to spontaneously combust less than previous models, and also has the equipment necessary to clean out and restore functionality to inoperable experiments.
