Despite helping mankin move forward for decades, nasa has a bit of a nostalgic sense to it. This week, the space agency unveiled an image of earth from the apollo 10 taken 36,000 nautical miles away. The image is from may 18, 1969, nearly 50 years ago. In the image, almost all of mexico can be seen, but the yucatan peninsula is covered by clouds. Apollo 10 was the fourth mission in the apollo space program and the second to orbit the moon.
