REDESPA is a new Planetology and Astrobiology network in Spain, led by a Board of 40 experts from different disciplines and from more than a dozen Spanish organizations including the Spanish National Research Council, National Institute of Aerospace Technology, Centro de Astrobiología, National Astronomic Observatory, and Science Museum of Castilla-La Mancha. REDESPA’s mission is to share information and be an open platform about scientific subjects as well as educational, ethical, and societal issues. In the context of REDESPA, we have also launched a specific chapter for young researchers (JIPA: Jóvenes Investigadores en Planetología y Astrobiología). The Membership registration in REDESPA is free and open to all interested people.
