The European Space Agencies (ESA) Microgravity Database "gives scientists access to information regarding all experiments carried out on ESA and NASA missions by European scientists since the 1960s." Users choose from a physical or life sciences query form, then can search by experiment and investigators, mission and facility, publications and source, and more. Results provide the mission name, data, payload, research subject, publication information, an abstract, and any other available facts or related links. A very intuitive and well designed database, visitors should appreciate its unique and extensive content.
