The space environment is not suitable
for human life due to the lack of some components, e.g. oxygen and water,
and the ionizing radiation, energy and particles, coming from the explosions
on the stars surface. The astronauts living on the International Space
Station (ISS) are undergoing an amount of that radiation because of
the Earth geomagnetic shielding and the ISS hull. The possibility of
measuring the background radiation on a Space Mission is thought to
be useful for future mission designs.
UTBI is the name of the project of the
students from the Universidad de Valencia which consists on sending
a Gamma and X ray detector to the ISS.
The experiment has two
significant but different purposes: on one hand, its main goal is to
provide a technology demonstrator of one of the Space Missions in which
the University of Valencia is involved, ASIM. The main scientific aim
is to measure the background radiation in a Space Mission, specifically
the radiation inside the International Space Station.
- Technological demonstrator:
we are going to use, for first time, a Solid State CdZnTe Detector
in the ISS. These detectors will be flown on the future external payload
of the European Columbus Modules, ASIM.
- Physical and Life Science:
The principal goal is the measurement of the radiation on board the
ISS. With these data, it will be possible to predict the effects of
radiation on the astronauts.
As we know the composition
of the ISS module hull, we would like to give some useful experimental
data of the background radiation on the ISS. This background radiation
measurement will allow the people involved in ASIM project to determine
the instrument performances.
