Piggybacking Astronomical Hazard Investigations on Scientific Big Data Missions

Current and upcoming large optical and near-infrared astronomical surveyshave fundamental science as their primary drivers. To cater to those, thesemissions scan large fractions of the entire sky at multiple wavelengths andepochs. These aspects make these data sets also valuable for investigationsinto astronomical hazards for life on Earth. The Netherlands Research Schoolfor Astronomy (NOVA) is a partner in several optical / near-infrared surveys.In this paper we focus on the astronomical hazard value for two sets of those:the surveys with the OmegaCAM wide-field imager at the VST and with the EuclidMission. For each of them we provide a brief overview of the astronomicalsurvey hardware, the data and the information systems. We present first resultsrelated to the astronomical hazard investigations. We evaluate to what extentthe existing functionality of the information systems covers the needs for theastronomical hazard investigations
