We call it the "Dark Side," but that’s basically a lie. It isn't dark. It gets just as much sunlight as the face we see every night while we’re stuck in traffic or walking the dog. The only thing "dark" about it is that it stayed hidden from human eyes for roughly four billion years. Think about that. Every human who ever lived—from cave painters to Galileo—looked up and saw the exact same craters. Then, in 1959, we finally got our first pictures of the back side of the moon, and honestly? It looked nothing like what people expected.
For a long time, people assumed the back would look just like the front. Why wouldn't it? But the first grainy, noisy images from the Soviet Luna 3 mission revealed a landscape that was weirdly lopsided. While the "near side" is covered in those dark, flat patches we call maria (ancient lava seas), the far side is a rugged, battered mess of highlands and impact craters. It looks like the moon used itself as a shield to protect Earth from every rogue space rock in the neighborhood.
The 1959 Grainy Breakthrough
Before the Space Race really kicked into high gear, the Soviet Union managed to slingshot a little probe called Luna 3 around the moon. This thing was a feat of sheer engineering duct tape and genius. It didn't have a digital sensor; those didn't exist yet. Instead, it took photos on 35mm film, developed them inside the spacecraft using an automated mini-lab, and then scanned them with a light beam to transmit the data back to Earth via radio waves.
The images were terrible by today’s standards. They were blurry, full of static, and looked like a photocopied ghost. But they were the first pictures of the back side of the moon ever seen by human eyes. It was a massive geopolitical flex. More importantly, it showed that the moon has a crustal dichotomy. Basically, the crust on the far side is much thicker than the side facing us. Scientists like Dr. Maria Zuber have spent decades trying to figure out why. One theory suggests Earth’s heat, back when the planet was a molten ball of fire, kept the near side of the moon hot and thin, while the far side cooled down and thickened up.
Apollo 8 and the Human Perspective
While robots got there first, nothing beats the human reaction. In December 1968, the crew of Apollo 8 became the first people to actually see the far side with their own eyes. Jim Lovell famously remarked that the moon looked like "whitish grey, like dirty beach sand."
When they drifted behind the moon, they lost all radio contact with Houston. Total silence. For those 45 minutes of "Loss of Signal," they were the most isolated humans in history. They took high-quality, handheld pictures of the back side of the moon using Hasselblad cameras. These photos weren't just scientific data; they were art. They showed the Tsiolkovskiy crater, a massive impact site with a dark floor that looks like a giant ink blot against the bright lunar highlands.

The Lunar Reconnaissance Orbiter (LRO) Era
Fast forward to the 21st century, and we don't have to rely on grainy film anymore. NASA’s Lunar Reconnaissance Orbiter has been circling the moon since 2009, and it has mapped the entire surface in terrifyingly high resolution.
If you look at modern pictures of the back side of the moon from the LRO, you can see individual boulders the size of a car. You can see the tracks left by lunar rovers. You can see the South Pole-Aitken basin, which is one of the largest, deepest, and oldest impact craters in the entire solar system. It’s about 1,550 miles wide. If that hit Earth today, we wouldn't be worried about our Wi-Fi—we’d be extinct.
Why the Far Side is a Radio Silent Paradise
Astronomers are obsessed with the far side for a reason that has nothing to do with photography. Because the moon is tidally locked—meaning the same side always faces us—the back side is permanently shielded from all the "noise" of Earth. No FM radio, no TV signals, no cell phone interference.
This makes it the "quietest" place in the local solar system. Scientists are currently planning to put radio telescopes there to peer back into the "Dark Ages" of the universe. They want to see the first stars forming, and they can't do that from Earth because our own technology drowns out the faint signals from the Big Bang.
China’s Chang’e 4: Touching the Untouched
For a long time, we only had pictures of the back side of the moon taken from orbit. No one had actually landed there because communicating with a lander on the "back" is a nightmare. You can't send a signal through the moon itself.

In 2019, the China National Space Administration (CNSA) pulled it off with the Chang’e 4 mission. They had to launch a separate satellite, Queqiao, just to act as a mirror to bounce signals from the far side back to Earth.
The images they sent back were breathtaking. They showed a landscape that was much more yellowish-grey than the Apollo photos suggested, mostly due to the specific mineral composition of the Von Kármán crater. We saw the Yutu-2 rover rolling across the dirt—a lone machine in a place that had been silent for eons. These photos proved that the far side isn't just a rugged wasteland; it’s a geologically complex region with a completely different history than the side we see from our backyards.
Common Misconceptions About These Images
People love a good conspiracy. Whenever a new batch of pictures of the back side of the moon drops, the internet goes wild looking for "alien bases" or "monoliths."
- The "Moon Hut": In 2021, the Yutu-2 rover spotted a cubic object on the horizon. The internet called it an alien base. As the rover got closer, it turned out to be... a rock. A small, rabbit-shaped rock.
- The Tower: Early grainy photos sometimes showed vertical streaks that looked like towers miles high. These were actually just "bit errors" in the data transmission or scratches on the original film.
- The Permanent Darkness: Again, it’s not dark. A "day" on the moon lasts about 29.5 Earth days. The far side gets two weeks of straight sunshine followed by two weeks of night.
The reality is actually cooler than the conspiracies. We are looking at a "time capsule" of the early solar system. Because the moon doesn't have wind, rain, or plate tectonics, those craters have stayed exactly where they are for billions of years. When we look at pictures of the back side of the moon, we are looking at the scars of the universe's violent childhood.
How to View These Images Yourself
You don't need a PhD or a security clearance to see these things. NASA and other space agencies have made their archives public.

- LROC Quickmap: This is basically Google Earth for the moon. You can zoom in on the far side and see the actual photography from the Lunar Reconnaissance Orbiter.
- ASU Moon Archive: Arizona State University maintains an incredible repository of every Apollo-era photo. You can see the raw scans, including the mistakes and the overexposed shots.
- The Lunar Reconnaissance Orbiter Camera (LROC) Gallery: They frequently post "featured images" that explain the geology of what you're looking at.
Why We Keep Taking Pictures
It’s about the future. The Artemis program aims to put humans back on the moon, and this time, we’re looking at the South Pole. This region sits right on the edge of the near and far sides.
The pictures of the back side of the moon we are taking now are scouting missions. We’re looking for water ice hidden in "permanently shadowed regions" (PSRs). These are craters at the poles where the sun never shines. If we find enough ice, we can use it for drinking water, oxygen, and even rocket fuel. The far side isn't just a photo op anymore; it’s a potential gas station for missions to Mars.
It’s easy to get desensitized to space photos. We see them on Instagram every day. But take a second to really look at a high-res shot of the lunar far side. There’s something deeply humbling about seeing a place that was "forbidden" to human eyes for millions of years. It’s a reminder that we live in a very small corner of a very large, very battered neighborhood.
Step-by-Step: Exploring the Far Side From Home
If you want to dive deeper into the visual history of the moon's hidden face, here is exactly how to do it without getting lost in a sea of low-quality memes.
- Navigate to the LROC QuickMap website. This is the gold standard for lunar data.
- Switch the projection to "Orthographic" and center it on the far side. You’ll immediately notice the lack of dark "seas" compared to the front.
- Layer on the "Digital Elevation Model" (DEM). This uses colors to show depth. The far side will look like a rainbow of extreme peaks and deep basins, revealing just how much more mountainous it is than the side facing Earth.
- Search for the "South Pole-Aitken Basin." Look for the deep blues and purples in the elevation map. This is where the most significant lunar research is happening right now.
- Check out the CNSA (China National Space Administration) archives. Look specifically for the Chang'e 4 and Chang'e 6 landing site panoramas. These offer the only "ground-level" view we have of the far side's surface.
By spending even ten minutes with these tools, you'll realize that the "back" of the moon isn't just a backup version of the front. It’s a completely different world with its own story to tell.
