The last human to walk on the moon was Eugene Cernan, commander of the Apollo 17 mission, on December 14, 1972. That was 43 years ago, and to this day, the Apollo program is still the high point of crewed space flight. Apollo missions are still the only ones that ever sent human beings to walk on another (natural) celestial body of any sort.

Earlier this month Kipp Teague, the founder of the Apollo Project, (independent from NASA) added a Flickr gallery of photos that were painstakingly scanned from the original film rolls astronauts took with large-format Hasselblad cameras. The photos themselves were in the public domain—they just weren't available so easily online, at such high resolution.

Some photos in the stream are recognizable; the iconic shot of Buzz Aldrin standing with the reflection of the Apollo lunar module in his visor is among the images. But some are less so: two of the astronauts on the mission, one of them Apollo 13 astronaut Jack Swigert, working to ensure they'd survive the near tragic voyage. And there are less dramatic, but human moments: Harrison "Jack" Schmitt shaving in the Apollo 17 lunar module, Ronald Evans spacewalking during Apollo 12's return trip to retrieve film, or his crewmates Schmitt and Gene Cernan sitting together, grinning on the trip home.
