On July 17, 1975, something that was unimaginable at the time happened: After years of the arms race and secrecy, an American Apollo and a Soviet Soyuz capsule docked with each other in Earth orbit for the first time. The Apollo-Soyuz Test Project (ASTP) was the first US-Soviet cooperation in space exploration and at the same time the beginning of a collaboration in space that continues to this day.
Since then, space travel seems to be one of the few areas where we humans can continue to work together despite (political) differences, tensions and disputes. We as humanity are united by the will to achieve great things and to bring about lasting change and progress in research in space and thus on Earth, then as now.
The original idea for Space Creator Day was to bring the space community closer together and create a basis for new ideas, projects, and community. To find new friends with the same enthusiasm for space travel and to pass this on to the next generation of people. So what could be a more fitting first motto for this year than: Unity.
