On December 11, 1972, Apollo 17 touched down on the Moon. This was not only our final Moon landing, but the last time we left low Earth orbit. With the successful launch of the Orion capsule, NASA is finally poised to go further again. So it’s important to remember how we got to the Moon — and why we stopped going.
If you’re wondering about the mechanics behind why the Moon looks bigger than usual tonight, or what that has to do with a lunar eclipse, this quick NASA animation will explain the basics of tonight’s astronomical event.
