Currently, the European Space Agency (ESA) is in the process of evaluating which of the proposals received in response to its announcement of opportunity earlier this year will fly. All those in contention have passed scientific peer review and are considered to be broadly compatible with space-based research.
There are practical limitations on the kinds of experiments that can be undertaken. For example, ...
