Scott Kelly's Expedition 45 EMU backup patch flown on the International Space Station as part of the One-Year Mission. The embroidered 2 x 3.25 insignia patch is attached to a fabric Velcro-backed mount that measures 3.5 x 3.5. In fine condition. Accompanied by a signed letter of authenticity from Kelly, which reads, in part: "This letter certifies that the accompanying Expedition 45 Extravehicular Mobility Unit (EMU) spacesuit patch was flown aboard the International Space Station. Expedition 45, which began on Sept. 11, 2015 and extended to Dec. 11, 2015, was the third of four increments during the first year-long mission on the space station…Though I performed two of my three extravehicular activities (EVA) during Expedition 45, this patch was flown to the space station as a backup to the one that was attached by Velcro to the front of my EMU spacesuit. The Expedition 45 patch was returned to Earth, having never been used on a spacewalk, as a memento of my 340 days orbiting the planet." The One-Year Mission was a scientific research project aboard the International Space Station, which studied the health effects of long-term spaceflight.
