The official insignia of the three-member Expedition 57 crew
Humans are explorers. We live on a cosmic island. Setting sails towards new worlds has always been our nature, and it is key to our survival. As soon as our ancestors learned how to build ships, they not only used them to sail up and down the coasts, but ultimately they set out to travel beyond the horizon, to discover new continents. The time of space exploration has just begun, a mere blink of an eye in the eon-long history of human exploration. And yet we already have successfully built great ships to sail the black heavenly seas, and we have dared adventurous journeys into the unknown.
The Expedition 57 patch is a tribute to human exploration. It depicts an explorer's ship leaving for the unknown as our early ancestors did, and is shaped like an arrow, heading out to new cosmic horizons. It highlights the purpose of the International Space Station as a world class science laboratory for the benefit of mankind and international cooperation, as well as humanity's flagship in space, preparing us for the amazing voyages ahead.
The Expedition 57 patch is dedicated to all those thousands of humans who make this journey possible through the contribution of their passion, hard work, and courage to one of the most fascinating projects in human history.
