    IMPACT is a successful merger of many different science communities that need similar instrumentation and resources. IMPACT is a merger of IMPF and ICAPS, originally conceived as two separate experimental facilities, both with their own development history. In May 2002, the dedicated scientific advisory boards for the IMPF and ICPAS recommended the combination of the two experiments into one ESA research laboratory. Both projects share hardware, space station accommodation and operations, and data processing and downloading functions in common. By consolidating these systems into a single laboratory significant reductions have been made to the overall project cost, by eliminating the duplication of expensive development, manufacturing, and qualification tasks.
