The weightlessness environment: what are the advantages?
Scientists exploit the unique conditions that exist in space,
particularly the microgravity environment, for conducting
research that would not be possible to perform on Earth, and to
improve and optimise processes on Earth that could lead to
important results in medicine, engineering and technology.  Why
research in microgravity?  Gravity can be a disrupting factor
for scientists, because it may distort the underlying physical
processes they attempt to study. It is fundamental for
scientists to create microgravity conditions in order to better
observe and control phenomena and processes that are normally
masked by the effects of gravity, and to perform experiments
that would be impossible on the Earth's surface.  A microgravity
environment provides an extraordinary laboratory, where
phenomena and physical processes can be observed without the
distortion experienced on Earth. The changes in fluid behaviour
in microgravity lie at the heart of the studie
