I did this for most of the path and then overlaid these images on the Garriott map to compare the old and new paths. Here is the result. The old map looked good but it was offset from the true position. The most interesting observation is that the rover drove further than previously thought. It started further north and drove further south than the old map showed (left edge), and ended (far right) further north again. Then it got more interesting...

The map of the landing area is here overlaid with greatly reduced LRO images. They are aligned with craters and other features. The tracks are shown in red and do not match the old tracks very well. The shape is roughly correct but the path is offset, typically by about 500 m.

The plains of eastern Colorado probably had their zenith in the early 20th century, prior to the great sand storms of the Dust Bowl. And it's been declining ever since. But for one moment in the 1990's a few counties sought to rebrand themselves as the "Colorado's Outback", somehow piggybacking off the success of the Crocodile Dundee films(?).
The rebrand didn't take.

Sadly there was no big official report on the mission as we had for earlier landers. It would have set me straight. So I blundered atrociously and made this awful map. Now I can correct the story. Oddly I received very little flak for this even from my Russian colleagues (though I expect they made merry about it over a glass of vodka in my absence). Now you know how much trust you can put into anything I say. Now we can move on to what LRO revealed. #maps #moon #luna21 #lunokhod2

A map of the Luna 21 landing site made using the flipped panoramas and therefore also flipped. It shows the lander (in the wrong orientation) and tracks (in the wrong places). Despite all its flaws the problem was not caught and it appeared in my old Moon book. A new project is going to correct everything.

Poll time! Do you use What3Words?

Given the feedback I've received, I updated the poll options to better reflect the sentiment.

Interestingly, I've made polls & posts about some pretty taboo subjects, but (short of the Tesla post that got me a few death threats last month) this poll has been the thing that seems to have garnered the most negative responses to date.

TIL people on Fedi have stronger feelings about a proprietary map system than about what counts as having had sex.

"Altogether, the team collected a staggering 82 million individual points of data, revealing the benighted depths below that colossal sheet of ice in remarkable detail... The map lets us perceive the continent as it was about 35 million years ago. Then, it would have been free of ice sheets & instead speckled with patches of tundra & swaths of lush coniferous forests. Now all that land is covered by 6.5 million cubic miles of ice."

Atlas Obscura Groundbreaking New Map Unveils Antarctica’s Hidden World Scientists compiled decades of data to reveal the continent hiding beneath millions of miles of ice. by Robin George Andrews, April 2, 2025 Scientists have unveiled the most detailed map of Antarctica’s hidden landscape, revealing towering mountain ranges, deep canyons, and bedrock that predates the ice itself. Using cutting-edge technology, they’ve peered through miles of ice to expose a world that could shape our understanding of climate change. See what lies beneath the frozen continent. Published by the British Antarctic Survey in March 2025, Bedmap3 is the highest-resolution map ever made of the geologic underworld beneath Antarctica’s ice sheets. Pritchard, H., et al (2025) / British Antarctic Survey "The deeper you go, the lower the resolution gets. The seismic waves that bounce back contain information about their journeys, but much of that is open to interpretation. So when I see something like the British Antarctic Survey’s new map of the Antarctic bedrock, I can’t help but feel gleeful—as it happens, it’s a lot easier to peer through ice than it is to see through rock."

Garriott was a computer game pioneer and son of a Skylab astronaut. He flew to the ISS in 2008 with Space Adventures. Round about that time (my Moon book was out but LRO was not in orbit) he contacted me about a map of the Lunokhod 2 area. This is the map I made.

How will this compare with what LRO showed us?

A map of the Lunokhod 2 route made at the request of Richard Garriott, who owns them after NPO Lavochkin auctioned them in 1993. The map has the same base as the previous posts - Apollo 15 images - and shows the full route from the landing site at upper left to the end of drive at the right edge.

This is the rest of the Lunokhod 2 map as it was published in 2007, in three sections. The letters signify different experiments, but we will see more of that later. The problem with the map is the way the line is placed on the base map. Then its position could only be guessed, now we can actually see the tracks. Also, as we are going to see, many fine details are omitted here.

The rest of the Lunokhod 2 map in 3 sections, as originally published.

Putting all this together - a base of Apollo 15 images, the Russian maps and location data - I made the maps which appeared in my old lunar exploration atlas. Here they are over two posts. This was the best that could be done at the time. Unfortunately I added some other details which were catastrophically wrong. But let's just enjoy these maps for the time being...

The first section of a map of the Lunokhod 2 route compiled from Apollo 15 images and the traverse details from Russian maps. This was in my atlas of lunar exploration in 2007. We can do so much better today.
