The final mission to the moon. The Apollo program was originally going to have an Apollo 18 and 19 (and they had already produced the CSM, lunar lander, and Saturn V for these) but NASA underwent budget cuts, and Apollo 17 was now to be the Swan Song for the Apollo lunar program.
The mission had many firsts, it was the first mission to have a civilian geologist aboard (Schmitt) and first to have a roadside repair in space. During deployment the Rover's fender was ripped off, and whenever the astronaut's drove it moon dust would be kicked up by the rover's tires and into the astronaut's faces.
To fix this they used a topographical map and some duct tape. And it worked! They were able to make the last mission one for the books.
And after all their EVAs at least it was time to go home. Gene Cernan was the last to enter the capsule, making him the last man to step foot on the moon.
And when the Lunar Module took off for a final time the camera on the front of the rover was finally able to capture it lifting off.
And for half a century the moon has remained untouched by human hands. Explored only by robotic satellites mapping its surface and occasionally landers touching down to make a survey.
But NASA's Artemis program now offers a glimmer of hope. Promising to send humans to the moon in 2024. Once again our horizons will have grown. And our rockets will be pointed to Mars.
