From the International Space Station, NASA astronaut Megan McArthur photographed the city of St. Louis, Missouri, including Gateway Arch National Park in October 2021. The image was taken at sunset, with the shadow of the Gateway Arch across the river visible from low Earth orbit. On Oct. 28, 2021, McArthur shared the image on social media to mark the 56th anniversary of the date the final piece of the Gateway Arch was put into place.
