Related: How does the Laboratory work?
I had a orbital station with 1x Mobile Processing Lab (MPL-LG-2) in LKO. With another small vessel I did a tour of Mun and Minmus, collecting science as I went and finally docking with the station. Now I've got way too much data being processed way too slow.
If I dock another MPL (or 2), will they work my existing station? Will I be able to process data faster? Do they interact? Or should I just launch another MPL to rendezvous (but not dock) and manually transfer the science?
