 Hello from EarthOrbit, I'm U.S. Army Colonel and Medical Corps Officer and NASA astronaut Andrew Morgan, currently serving 250 miles above the Earth on the International Space Station. This week marks the 75th anniversary of what was the largest airborne operation in history, Operation Market Garden. This operation has special significance for me because my great-uncle, Clink, Harry McClinic, was a paratrooper in the 506 Parachute Infantry Regiment, 101st Airborne Division, and was wounded in combat shortly after jumping into this operation. Operation Market Garden was actually two separate operations in the Netherlands. Operation Market was the airborne operation designed to assault and seize key bridges with over 34,000 airborne troopers, and Operation Garden was a ground attack designed to exploit these bridge crossings. Although Operation Market Garden failed to achieve its strategic goals, at the time it was a justifiable attempt to shorten the war. From a young age, I was strongly influenced by stories of my uncle, Clink, and his jump at Normandy and Market Garden, and it's been my honor to bring some of his insignia, awards, and patches with me on my nine-month mission to the ISS. In addition, the National Museum of the U.S. Army provided a World War II medical brassard similar to the one likely worn by medics that tended to my uncle, Clink, in 1944. Surrounded and outnumbered, deep in enemy territory with only what they could carry, airborne troopers and Operation Market Garden epitomized what it means to be an airborne soldier. I'm proud to be counted among their ranks today, continuing their legacy and representing them on the ultimate high ground. Airborne all the way. Go Army.
