Mission insignia for International Space Station (ISS) Expedition 70
The Expedition 70 patch is designed around the central yin-yang symbol representing balance; first and foremost, the balance of our beautiful planet Earth that is encircled by the yin-yang symbol and which forms part of the Expedition number. In our exploration of space, we are reminded of the uniqueness of Earth; the further we push the boundaries of human existence, the stronger our longing for our home planet grows. As our understanding of the cosmos expands, so does our understanding of Earth, and although we live in an ever-changing world, we recognize the need for a planet in balance to ensure our future.
Space exploration is also about creating the future of our dreams. The tentative first steps we take today will hopefully become a well-trodden path in the future. This is represented stylistically by the “retro-futuristic” design of the patch, which mimics the design of the posters depicting the future from the early days of the space age. It is also emphasized by the yellow, orange, and red colors suggesting a sunrise. Lastly, the dynamism in the depiction of the number 7 suggests not only the physical launch into space, but also humanity’s progress towards the future.
