CHEMICAL MEASUREMENTS OF NIM
ON JUICE, ESA MISSION TO JUPITER
SATELLITES (2028)

Statement of the Problem: JUICE, the L-class mission of ESA to explore the
Jupiter system will deliver chemical measurements of the Jupiter satellites
exospheres, the icy moons Europa, Ganymede and Callisto. One of the in-
struments in the PEP consortium employed on the mission will the neutral
gas mass spectrometer as part of the particle consortium (PEP). We develop
prototypes of the instrument to test against the physical and environmen-
tal conditions expected in the Jupiter environment, and measurements near
these moons. The exospheres of the icy moons are populated by material
originating directly from the moons’ surfaces, thus NIM measurements can
be inverted to derive the chemical composition of the surface. By studying
the composition of all three icy moons we will also get crucial information
on the evolution of these objects with time, since they started from the same
chemical inventory. We started unique laboratory experiments simulating the
icy surfaces of these moons and their response to particle radiation in form-
ing their exospheres; in parallel we develop necessary shielding against the
high energy radiation to protect the instruments and theoretical models of
the atmospheres of these moons, both in preparation of the science phase
of this mission.

ty, Switzerland. Currently, he is the staff member of plan-
etary sciences and space research division and head of
Laser mass spectrometry lab in Physics Institute Bern.
He is involved in the development of a miniature analyti-
cal instruments for space missions. Currently, He is a Sci-
ence Group Member for the missions to The Moon (Luna
Glob, Luna Resurs) and Jupiter satellites(JUICE). Marek
