He knew it was the end. When Eugene Cernan climbed the ladder of the Lunar Module Challenger on December 14, 1972, he wasn't just finishing a work shift. He was closing a door that hasn't been reopened in over half a century. We often talk about Neil Armstrong because being first is everything in our culture, but Cernan, the last man on the moon, carries a heavier sort of historical weight. He lived the rest of his life knowing he was the final human to feel lunar dust under his boots.
It’s been over 50 years. That’s a staggering amount of time when you consider the tech leaps we’ve made since then. Your smartphone has more computing power than the entire NASA facility in 1972. Yet, we haven't been back.
The Final Footprint
Gene Cernan didn't just walk; he drove. Along with Harrison "Jack" Schmitt, the only actual scientist to ever visit the moon, Cernan explored the Taurus-Littrow valley. They spent about 75 hours on the surface. That is a long time to be away from home. They covered 22 miles in the Lunar Roving Vehicle. If you look at high-res photos from the Lunar Reconnaissance Orbiter today, you can still see those rover tracks. They aren't going anywhere. There’s no wind to blow them away.
Before he left, Cernan knelt down. He used his finger to etch his daughter’s initials, TDC (for Tracy Dawn Cernan), into the lunar regolith. It’s probably the most permanent "I was here" note in human history. Honestly, it’s those little human moments that make the Apollo 17 mission feel less like a Cold War flex and more like a genuine human milestone.
Why did we stop?
People always ask why we stayed away so long. It’s a mix of money and shifting priorities. The Apollo program was incredibly expensive. By the time Apollo 17 rolled around, the American public was getting bored. Ratings were down. Vietnam was draining the budget. The "Space Race" was technically won, and the political will to keep spending billions on rocks just evaporated.
Cernan himself was often frustrated by this. He spent decades as a sort of ambassador for space, constantly pushing for a return. He didn't want to be the last man on the moon. He wanted to be a footnote in a long list of lunar explorers. Instead, he became a trivia answer.
The "Orange Soil" and Real Science
Most people think of Apollo missions as just flag-planting exercises. That’s a mistake. Apollo 17 was a massive scientific success. Schmitt, being a geologist, noticed something weird at Shorty Crater: orange soil. It looked completely out of place against the monochrome gray of the moon.
It turned out to be tiny beads of volcanic glass. This was huge. It proved that the moon had a much more violent, volcanic past than some scientists originally thought. They brought back 243 pounds of rocks and soil. We are actually still studying those samples today. NASA kept some sealed for decades, waiting for better technology to analyze them.
Life After the Moon
What do you do after you've walked on another world? For Cernan, it was a weird transition. He retired from the Navy and NASA in 1976. He went into the private sector, but he never really left the moon behind. He wrote a book called The Last Man on the Moon, which is surprisingly raw about the toll the mission took on his personal life.
The pressure was immense. You have to be a certain kind of "alpha" personality to sit on top of a controlled explosion and fly 240,000 miles away. That doesn't always translate well to a quiet suburban life. Cernan was open about the fact that his career contributed to his divorce. It's the part of the "hero" narrative we usually gloss over.
Misconceptions about Apollo 17
Some people think the mission was cut short or that they saw something they shouldn't have. Total nonsense. The mission went exactly as planned, even though they had to fix a broken fender on the rover using duct tape and some maps. Yes, duct tape saved a multimillion-dollar moon mission.
Another weird myth is that Cernan was the only one there. He was just the last one back into the module. Jack Schmitt was right there with him. But because Cernan was the commander, he was the final person to step off the surface. Those final words he spoke are worth remembering. He didn't just say goodbye; he said he hoped we would return with "peace and hope for all mankind."
The Artemis Reality Check
We are finally, supposedly, going back. NASA’s Artemis program is the successor to Apollo. But it’s different this time. Instead of just "flags and footprints," the goal is a sustained presence. They want a space station in lunar orbit called Gateway.
- Artemis I: Already happened. Uncrewed test.
- Artemis II: Taking humans around the moon but not landing.
- Artemis III: This is the big one. The goal is to land the first woman and the next man.
If Artemis III succeeds, Gene Cernan will finally lose his title. And honestly? He’d be thrilled about it. He passed away in 2017, still the record holder.

The Difficulty of the Return
Why is it so hard to go back if we did it in the 70s? We lost the "muscle memory." The factories that built the Saturn V rockets are gone. The engineers who knew the quirks of the systems are mostly retired or gone. We aren't just "going back"; we are rebuilding the entire infrastructure from scratch with modern safety standards.
The moon is also a brutal environment. The dust (regolith) is like powdered glass. It ruins seals and gets into lungs. It smells like spent gunpowder, according to the astronauts. Figuring out how to live in that for weeks instead of days is a massive engineering hurdle.
Actionable Insights for the Future
If you want to keep up with the legacy of the last man on the moon, you shouldn't just look at history books. Keep an eye on the SLS (Space Launch System) launches and the development of the Starship HLS (Human Landing System). These are the literal vehicles that will retire Cernan’s title.
- Follow the NASA Artemis updates monthly to see how the timeline shifts.
- Watch the documentary The Last Man on the Moon to understand the psychological impact of the mission.
- Look at the Lunar Reconnaissance Orbiter (LRO) gallery online. You can see the Apollo 17 landing site in terrifyingly clear detail, which effectively debunks any "hoax" theories in about five seconds.
We are currently in a new space race, but it’s not just two countries anymore. It’s dozens of countries and private companies like SpaceX and Blue Origin. The moon isn't a destination this time; it's a gas station and a laboratory for going to Mars. The 50-year gap between Cernan and the next boots on the ground will likely be remembered as a strange lull in human history, a moment where we looked at the stars and then looked away. But the focus is back. The tracks Gene Cernan left in the dust are still there, waiting for company.
