In april 2023, Peter Barthel initiated a project for elementary school children, around the famous image of earth made by the NASA/ESA Cassini mission in 2013. Goal of the project is to educate children about Earth Day (April 22). Three short films were produced, together with Joanna Holt and Marieke Baan of the national astronomy research school NOVA, popular biologist Freek Vonk, and filmer Koen de Koning. The films are essential elements of a lesson about our unique planet, produced and distributed by the national Dutch on-line education platform Nieuwsbegrip. A Challenge, part of the project, was won by the Brederoschool in Groningen.
