IMPF Philosophy

Fully equipped laboratory for ISS plasma experiments

Facility operational for 10 years

Highly modular facility design

– Experiment insert = 1 locker

– Supporting hardware = 3 lockers

Flexible accommodation on ISS (political decision, barter object)

Insert exchange cycles

– experiment e.g. 6 months

– other inserts about 2-3 years
