Since 2016, I became a member of the ESA Planetary Science Archive User Group, PSA-UG. The PSA-UG is formed by invitation from ESA and comprises 6-8 active and external scientists who advise ESA on best archiving practices of solar system exploration data to ensure they meet the communitys needs. We meet a couple of times a year. You can read more on the ESA PSA-UG and its mandate at:
