What is biodiversity? How do flowers affect us and the environment? And how are they related to spaceflight? For primary school children to be able to investigate these exciting questions, the German Space Agency at DLR sent two kilograms of wildflower seeds to the International Space Station ISS on 29 August 2021.
These 'space seeds' were on the International Space Station (ISS) together with German European Space Agency (ESA) astronaut Matthias Maurer during his Cosmic Kiss mission. They landed safely back on Earth on 24 January 2022.
On 7 September 2022, the astronaut and a primary school class planted a small portion of these seeds on the UN Campus in Bonn in cooperation with UN-SPIDER.
