It was 33 years ago ... on Taurus-Littrow
05:40:56 GMT, December 14th 1972, Gene Cernam climb back onboard Challenger, the lunar module that brought him and Harrison Schmitt down to the surface of the moon, after their last EVA (Extra-vehicular activity) which lasted 7 hours and 17 minutes. Over the 22 hours that the 2 astronauts spent outside the LM, the traversed 30km (18.64 miles) and collected more than 110kg (242.50lbs) of rock, beating all the previous missions. A real nice finale for the Apollo program.
The Smithsonian National Air and Space Museum have a nice set of pages on the Apollo program where we can find the map of the EVA and LRV (lunar roving vehicle) traverses:
As well as a comparaison between all the Apollo flights that landed on the Moon:
As I finished Moondust last night, I can said that even thought both moonwalkers are smiling in the above picture, Gene Cernam wasn't too happy to have that particular geologist on his mission ... who by the way very recently released a book (his first?) Return to the Moon: Exploration, Enterprise, and Energy in the Human Settlement of Space. Now, don't get all excited, from what I have seen that book isn't about his Apollo experience :-)
