In November 2022, the next UN World Climate Conference will take place in Egypt. And it will reconfirm what we have known for years: Something has to change. And we can change something – from space. Data from satellites in low-earth orbit allow us to conduct comprehensive real-time research on the climate, make informed decisions and take action. Small launch vehicles from Europe make it possible to transport these satellites and thus form the foundation of an ecological space travel, called Green New Space.
