Mobile Processing Lab MPL-LG-2 - Kerbal Space Program Wiki
The Mobile Processing Lab MPL-LG-2 generates a far greater amount of Science from experimental results by first converting them into a cache of "data" which is then slowly "researched" into stored science by Scientists, over the course of many days.It can also be used to "Level Up Crew" who have gained sufficient experience, throughout the craft, without returning to Kerbin.
