| Zusammenfassung |
| In recent years the Moon has become again a target for exploration activities, as shown by
many performed, ongoing or foreseen missions. The reason for this new wave are manifold.
The knowledge of formation and evolution of the Moon to current state is important in
order to trace the overall history of Solar System. An effective driving factor is the
possibility of building a human settlement on its surface, with all the related issues of
environment characterization, safety, resources, communication and navigation. Our
natural satellite is also an important laboratory for fundamental physics: Lunar Laser
Ranging is continuing to provide important data that constrain possible theories
of gravitation. All these topics are providing stimulus and inspirations for new
experiments.
ISA (Italian Spring Accelerometer) can provide an important tool for lunar studies.
Thanks to its structure (three one–dimensional sensors assembled in a composite structure) it
works both in–orbit and on–ground, with the same configuration. It therefore can
be used onboard a spacecraft, as a support to a radio science mission, and on the
surface of the Moon, as a seismometer. The first option has been explorated in the
context of MAGIA (Missione Altimetrica Gravimetrica geochImica lunAre), a
proposal for an exploration mission with a noteworthy part dedicated to gravimetry and
fundamental physics. The second option is candidate to be hosted on NASA ILN
(International Lunar Network) and ESA First Lunar Lander. After a description of the
instrument, both of them will be described and discussed, giving emphasis on the
integration of the instrument with the other components of the respective experiments. |
