The UK Space Agency (UKSA) is surveying the size and shape of the UK community engaged with microgravity and space environments research. The aim is to ensure an up-to-date and accurate picture of current research activity in the UK, to inform future planning and investment decisions. Say the UKSA:
We are interested in all research which uses one or more of the characteristics of space and/or space-analogue facilities which mimic these characteristics (i.e. microgravity, radiation, exposure etc.) These facilities include but are not limited to: the ISS, sounding rockets, parabolic flights, drop towers, bed rest, isolation facilities and radiation facilities.
