May 3rd, 2017 marks the 5,000th day of NASA's Spitzer Space Telescope mission. This video gives us a detailed look at six of these days, showing how an automated observatory like Spitzer, which is effectively an astronomy robot, spends its time. It’s overall mission design allows for an unprecedented degree of efficiency, allowing it to study the full range of astronomical phenomena including nearby objects in the solar system, stars in our galaxy, and galaxies out to the edge of the observable universe.
