«The International Space Station Expedition 40
Crew Patch (see Expedition 40 (NASA) ) symbolizes the past, the present and the future of human
space flight in the form of the reliable and proven Soyuz that has been
flying since the 1960s, the International Space Station our present home

"The ISS is the culmination of an enormous effort by many countries partnering to produce a first-class orbiting laboratory, and its image represents the current state of space exploration. The ISS is immensely significant to us as our home away from home and our oasis in the sky," the Expedition 40 crew wrote. "A blend of legacy and future technologies is being used to create the next spacecrafts which will carry humans from our planet to destinations beyond. The sun on Earth's horizon represents the new achievements and technologies that will come about due to our continued effort in space exploration."» in Expedition 40 (spaceflight101)
