Experiments on Martian Surface Properties and Processes

Experiments have a long tradition in geosciences and are considered to be a suitable tool to explore scenarios that are difficult or impossible to visit for an onsite measurement. However, experiments have limitations and results are often overinterpreted, or, as a consequence, received with undue skepticism. Therefore, some theory on use and limitation of experiments are required before moving on to designing instruments to test the effect of reduced gravity on sediment settling on Mars. This chapter presents first some general considerations researchers should take when planning an experiment. Based on these conceptual thoughts, the more specific aims of experiments in reduced gravity are defined, followed by a discussion of the constraints set for putting hardware onboard a reduced gravity flight.
