The intention of the HREDA (Human and Robotic Exploration Data Archive) information portal and data archive is to collect the results of the thousands of investigations performed in a broad spectrum of scientific fields. HREDA supports the global scientific community and the interested general public to make themselves accustomed with general information, the results and the generated data related to these experiments. The data archive is the depository of information on historical and on-going investigations related to the human space flight and exploration programmes within ESA. The Agency feels obliged to make those data and information publicly accessible.
There have been best possible efforts made to trace and secure information of six decades of European microgravity research. Some information is missing and some information is incomplete but still, the available content might aid the understanding of a specific scientific problem and the definition of further, meaningful investigations by the next generation of researchers.
HREDA is a joint effort by ESA’s Directorate for Human and Robotic Exploration, the Directorate of Science, and the Science Data Centre (SDC) Madrid. It became operational in 2020 and supersedes the former Erasmus Experiment Archive (EEA) and the ESA Microgravity Database (MGDB).
