Abstract :
The
International Space Station (ISS) has been permanently manned for over 14
years, orbiting 400 km above Earth.
A wide field
of science is performed there, spanning from fundamental physics over biology
to human physiology.
A short
video from the shuttle mission STS-128 will introduce ISS. A few examples of
experiments exploiting the
weightlessness will be mentioned, before going into details of JEM-EUSO. The large
JEM-EUSO collaboration aims
to study
Ultra-High Energy Cosmic Rays (UHECR; E > 10 EeV).
The principle is to observe the UV-light that is emitted
by the
Extensive Air Showers (EAS) with up to 100 billion particles, which are created
by the UHECRs. However,
these are
extremely rare and therefore a space based detector that can cover a very large
area is ideal, in addition to that
it gives
a uniform coverage of the whole celestial sphere. Currently a Russian-based design,
K-EUSO, is planned for ISS
around
2019. A small pre-cursor, Mini-EUSO, to be placed inside ISS in 2017, will in
addition to test and validate
technology
and operations, be able to make interesting scientific contributions in several
fields.
