The HRE Data Archive (HREDA) collects information and data of investigations funded or co-funded by ESA’s Directorate for Human and Robotic Exploration (HRE) and performed on microgravity and ground-based facilities since 1972. This portal is the official entry point that allows the user to navigate through the existing investigations and the generated datasets. It is a joint effort by ESA’s Directorate for Human and Robotic Exploration, the Directorate of Science, and the Science Data Centre (SDC) Madrid.
