  Laboratory studies for planetary science and astrobiology aimat advancing our
understanding of the Solar System through the promotion of theoretical and
experimental research into the underlying processes that shape it. Laboratory
studies (experimental and theoretical) are crucial to interpret observations
and mission data, and are key incubators for new mission concepts as well as
instrument development and calibration. They also play a vital role in
determining habitability of Solar System bodies, enhancing our understanding of
the origin of life, and in the search for signs of life beyond Earth, all
critical elements of astrobiology. Here we present an overview of the planetary
science areas where laboratory studies are critically needed, in particular in
the next decade. These areas include planetary & satellites atmospheres,
surfaces, and interiors, primitive bodies such as asteroids, meteorites,
comets, and trans-Neptunian objects, and signs of life. Generating targeted
experimental and theoretical laboratory data that are relevant for a better
understanding of the physical, chemical, and biological processes occurring in
these environments is crucial. For each area we present i) a brief overview of
the state-of-the-art laboratory work, ii) the challenges to analyze and
interpret data sets from missions and ground-based observations and to support
mission and concept development, and iii) recommendations for high priority
laboratory studies.
