The search for life outside the Earth has been one of the biggest quests of
mankind. We have reached a level in technology that allows the first steps
towards a scientific investigation. The aim of this workshop was to take an
interdisciplinary look at the signatures that would be indicative for past or
present life on another planet, to compare them to biosignatures on Earth, and
to discuss state-of-the-art in-situ instruments that are envisioned to search
for these signatures in the exploration of the solar system as well as concepts
for the search for habitable planets around other stars.
