| Zusammenfassung |
| In recent years the Moon has become again a target for exploration activities, as shown by
many missions, performed, ongoing or foreseen. The reasons for this new wave are
manifold. The knowledge of formation and evolution of the Moon to its 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 for testing
gravitation theories. All these topics are providing stimulus and inspirations for new
experiments: in fact a wide variety of them has been proposed to be conducted on the lunar
surface.
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 can
therefore be used onboard a spacecraft, as a support to a radio science mission, and
on the surface of the Moon, as a seismometer. This second option in particular
has been the subject of preliminary studies and has been proposed as a candidate
to be hosted on NASA ILN (International Lunar Network) and ESA First Lunar
Lander. ISA-S (ISA-Seismometer) has a very high sensitivity, which has already
been demonstrated with long time periods of usage on Earth. After a description of
the instrument, its use in the context of landing missions will be described and
discussed, giving emphasis on its integration with the other components of the systems. |
