On #MemorialDay, we remember and honor those who gave the last full measure of devotion in service to our country. Ad astra per aspera. Image description: A large American flag floats in the cupola of the International Space Station. The slightly rumpled flag, which takes up most of the photo's lower half, arcs across the cupola, roughly following its hexagonal walls. Above the flag, several of the cupola's windows look out onto Earth, where blue seas and white clouds fill the view. Credit: NASA/Scott Kelly #NASA #Space #SpaceStation #AdAstra
