NASA's Lunar Reconnaissance Orbiter (LRO) captured the sharpest images ever taken from space of the Apollo 12, 14 and 17 landing sites. Images show the twists and turns of the paths made when the astronauts explored the lunar surface.

The left image was released today; the right image is a zoom-in on an LRO image released in 2009. LRO was moved into a lower orbit to capture the new image. The images do not line up perfectly because of differences in lighting conditions, angle of the LRO Camera, and other variables.

At the Apollo 17 site, the tracks laid down by the lunar rover are clearly visible, along with the last foot trails left on the moon. The images also show where the astronauts placed some of the scientific instruments that provided the first insight into the moon's environment and interior.
"We can retrace the astronauts' steps with greater clarity to see where they took lunar samples," said Noah Petro, a lunar geologist at NASA's Goddard Space Flight Center in Greenbelt, Md., who is a member of the LRO project science team.
All three images show distinct trails left in the moon's thin soil when the astronauts exited the lunar modules and explored on foot. In the Apollo 17 image, the foot trails, including the last path made on the moon by humans, are easily distinguished from the dual tracks left by the lunar rover, which remains parked east of the lander.
"The new low-altitude Narrow Angle Camera images sharpen our view of the moon's surface," said Arizona State University researcher Mark Robinson, principal investigator for the Lunar Reconnaissance Orbiter Camera (LROC). "A great example is the sharpness of the rover tracks at the Apollo 17 site. In previous images the rover tracks were visible, but now they are sharp parallel lines on the surface."

At each site, trails also run to the west of the landers, where the astronauts placed the Apollo Lunar Surface Experiments Package (ALSEP) to monitor the moon's environment and interior.
This equipment was a key part of every Apollo mission. It provided the first insights into the moon's internal structure, measurements of the lunar surface pressure and the composition of its atmosphere. Apollo 11 carried a simpler version of the science package.
One of the details that shows up is a bright L-shape in the Apollo 12 image. It marks the locations of cables running from ALSEP's central station to two of its instruments. Although the cables are much too small for direct viewing, they show up because they reflect light very well.

The higher resolution of these images is possible because of adjustments made to LRO's orbit, which is slightly oval-shaped or elliptical. "Without changing the average altitude, we made the orbit more elliptical, so the lowest part of the orbit is on the sunlit side of the moon," said Goddard's John Keller, deputy LRO project scientist. "This put LRO in a perfect position to take these new pictures of the surface."
The maneuver lowered LRO from its usual altitude of approximately 31 miles (50 kilometers) to an altitude that dipped as low as nearly 13 miles (21 kilometers) as it passed over the moon's surface. The spacecraft has remained in this orbit for 28 days, long enough for the moon to completely rotate. This allows full coverage of the surface by LROC's Wide Angle Camera. The cycle ends today when the spacecraft will be returned to its 31-mile orbit.

"These images remind us of our fantastic Apollo history and beckon us to continue to move forward in exploration of our solar system," said Jim Green, director of the Planetary Science Division at NASA Headquarters in Washington.
LRO was built and managed by Goddard. Initial research was funded by the Exploration Systems Mission Directorate at NASA Headquarters. In September 2010, after a one-year successful exploration mission, the mission turned its attention from exploration objectives to scientific research in NASA's Science Mission Directorate.
Do I need a sarc tag?
Gee, thought it was all faked in a studio.

I'll be even more impressed when they photograph the golf bals
Where are the Soviet landing cites? HA HA HA HA HA!!!!!! Wheeze....
facked? Yes, I guess there are some idiots that still say that.
But when I lived in NM I knew one of the last 2 men to actually walk on the moon. He still lives there. Jack Schmidtt.
That mission really took some guts. I am still in awe about the whole Apollo Program.
Maybe I missed something, but, why did they leave the buggy so far from the Lander? Looks like they drove it off a ways and then walked back to the landing site for some reason.
Run it out of juice?
FReeper practice seems to be to not include photographs in posts talking about images or pictures. So, please forgive me for actually including photographs in an article talking about photographs. /s /rant
The fact that not a single one of the thousands of people who worked in the Apollo program have ever leaked a word about the hoax doesn't seem to deter the conspiracy loons.
I guess they're all sworn to secrecy on pain of death... /sarc
Yeah those loons have been pretty quiet lately haven't they?
Better view of the LM liftoff. It was away from the debris plume that resulted from the ascent stage breaking away from the lower stage. On 17 it gave the camera operator in Houston a wider angle to pan the camera up and follow the ascent stage almost out of sight.
I’ll believe it when I see the ‘Capricorn One’ photos.
The faking landers aren’t going to be happy about this are they?
That’s great. Very well done.
“Gee, what are we gonna do now that the last STS mission’s over with?”
“I dunno - maybe I’ll surf the hard-drive and see what I can come up with...”
Sheesh - and we’re paying these folks...
My brother has the same idea about 9/11, I tell him if it was an inside job, wheres the people out of the thousands that would have to have been involved blowing the whistle at? He says, “their families would be killed”. I just laugh.
They probably had more than a 1/100 chance of complete crew loss i.e. more than the space shuttle had. Lucky.
In the end, these became geology expeditions. Interesting at that level, more than the transportation aspect; but still ordinary.
I think the unmanned missions since have been just as spectacular.
It’s absolutely beyond me how anyone could say this was staged. The amount of cover up and sealed lips up to this point would’ve taken a monumental effort on an order never before seen in human history.
As an amateur astronomer, it still kills me when I’ve got my 14” Dob out on a clear autumn evening and some stranger comes and asks, “Can you see the lunar landing site with that thing?”
My bemused response is always to point the thing straight at the full moon and laugh as they squint through the lens.
