People remember the moon landing. They remember Neil Armstrong’s boots hitting the dust and the grainy black-and-white footage that made the world stop spinning for a second. But honestly, the end of that era—the last days of the space age—is way more interesting than the beginning. It was messy. It was heartbreaking for the engineers who had spent a decade living on caffeine and slide rules. By the time 1972 rolled around, the high-octane fuel of the 1960s had basically run out, replaced by budget cuts and a sudden, sharp realization that the moon was a very expensive place to visit.
We like to think of progress as a straight line. It isn't.
If you look at the flight manifest for Apollo 17, the final mission, you see the cracks. NASA originally had plans for Apollo 18, 19, and 20. The hardware was built. The Saturn V rockets—the most powerful machines ever constructed—were sitting in hangers, ready to go. Then, the Nixon administration pulled the plug. It wasn’t just about the money, though the Vietnam War and a shaky economy were eating the budget alive. It was a shift in vibe. The public was bored. Television ratings for the later moon walks were tanking. People were literally calling TV stations to complain that their soap operas were being interrupted by men driving a rover on another world.
The Apollo 17 Hangover
Harrison "Jack" Schmitt was a geologist. He was the first—and only—actual scientist to walk on the moon. Up until then, it had been all test pilots, the "Right Stuff" guys who were there to fly the ship and not crash. Schmitt was there to look at rocks. This shift toward science marked the true last days of the space age transition.
When Gene Cernan stepped off the lunar surface on December 14, 1972, he said some poignant words about returning with peace and hope. But back at Mission Control, the mood was different. It felt like a funeral. They knew they weren't going back. Not for a long time.
The Saturn V production lines had already been shut down. The specialized tooling was being dismantled. This is one of those facts that hurts to think about: we literally threw away the blueprints and the capability to go back. It’s like a civilization forgetting how to build a cathedral. While we had the Skylab missions and the Apollo-Soyuz Test Project in 1975, those were basically just using up the leftover parts. They were the epilogue, not the story.
Why did we actually stop?
It’s easy to blame the politicians. But the truth is more complicated. The "Space Age" was a product of a very specific geopolitical fever dream. Once the U.S. "won" the race to the moon, the existential dread of losing to the Soviets evaporated. Without that fear, the massive spending—which peaked at about 4% of the federal budget—became impossible to justify to a public worried about gas prices.

- The cost per launch was astronomical.
- Public interest fell faster than a returning command module.
- There was no immediate "return on investment" besides bragging rights and some cool rocks.
- NASA shifted focus to the Space Shuttle, a "truck" designed to stay in Low Earth Orbit (LEO).
The Death of the "New Frontier" Mentality
The last days of the space age weren't just about rockets. They represented the death of a certain kind of 20th-century optimism. In 1965, everyone assumed we’d have a base on Mars by 1985. Kubrick’s 2001: A Space Odyssey wasn’t supposed to be fantasy; it was a projection.
When the shuttle era began in the early 80s, space became "routine." It became a place where we went to fix satellites or conduct experiments in microgravity. That’s important work, don't get me wrong. But it’s not the same as voyaging into the abyss. The scale of our ambition shrank from "other worlds" to "250 miles up."
You can see this shift in the pop culture of the time. We went from Star Trek’s hopeful exploration to the gritty, lived-in, industrial future of Alien (1979). Space was no longer the shining city on a hill. It was a workplace.
The Skylab Incident
If you want a specific moment that felt like the final nail in the coffin, look at Skylab. It was America's first space station, built from a modified Saturn V third stage. It was brilliant, but it was also a victim of the transition. When it came crashing back to Earth in 1979, scattering debris across the Australian outback, it felt symbolic. The grand hardware of the 60s was literally falling out of the sky because we didn't have a way to boost it back up.
NASA didn't have a shuttle ready in time to save it. We had a gap. A long, quiet gap where American astronauts didn't leave the planet for six years.
A Different Kind of Age
Is the space age actually over? Technically, we’re in a "New Space" era now. SpaceX, Blue Origin, and the Artemis program are trying to pick up the threads we dropped in 1972. But the vibes are different. It’s commercial. It’s about Starship and reusable boosters and billionaire rivalries.

The original space age was a government-run, total-war-style mobilization. It was a feat of collective will that we probably couldn't replicate today even if we wanted to. We’ve traded the raw, terrifying power of the Saturn V for the efficiency of the Falcon 9. It's better for the checkbook, sure. But something about that original "last days" period still haunts us.
What we lost in the transition
When we stopped going to the moon, we lost a certain muscle memory. We lost the engineers who knew how to handle liquid hydrogen at that scale by "feel." We lost the audacity to fail publicly. The Apollo program had disasters—Apollo 1 was a nightmare—but they kept going. By the end of the last days of the space age, the tolerance for risk had plummeted.
This risk aversion is why it’s taking us so long to get back. We’re trying to build "safe" lunar missions, which is almost an oxymoron. The guys in 1969 were basically sitting on top of a giant bomb controlled by a computer with less power than a modern toaster.
How to Understand This History Today
If you want to really grasp what those final years felt like, don't just watch the documentaries. Read the technical debriefs. Look at the photos of the "Lunar Receiving Laboratory" being decommissioned.
To truly appreciate this era, you should:
- Visit the leftovers. Go to the Kennedy Space Center or the Johnson Space Center. Seeing a Saturn V in person is a religious experience. It’s way bigger than you think it is.
- Read "A Man on the Moon" by Andrew Chaikin. It’s the definitive account, focusing heavily on the later missions like Apollo 15, 16, and 17 that often get ignored.
- Track the Artemis timeline. Compare the goals of the 1970s to what we’re doing now. The mission architectures are surprisingly similar, proving that the Apollo guys actually had it right the first time.
- Watch "For All Mankind." Okay, it’s historical fiction, but it captures the "what if" heartbreak of that era better than almost anything else.
The last days of the space age weren't a failure. They were a pivot. We stopped looking at the stars and started looking at our own planet. We launched the Landsat satellites. We started monitoring the ozone layer. We realized that while the moon was beautiful, it was dead. Earth was the only place that breathed.

Maybe that was the whole point. We went to the moon to discover the Earth. And once we saw it—that "Blue Marble" photo from Apollo 17—we realized we had enough work to do back home.
The current resurgence in space travel isn't a new age, really. It’s the second act of a play that went on a 50-year intermission. We’re finally walking back into the theater, hoping the actors still remember their lines.
Actionable Next Steps
Start by looking at the NASA Image and Video Library. Search for "Apollo 17" and look at the high-res scans of the 70mm Hasselblad film. You’ll see the clarity and the desolation of those final missions. Then, check the current Artemis I and II flight schedules. Seeing the hardware for the SLS (Space Launch System) reveals how much of the "Space Age" tech we are actually recycling. If you're a data person, look up the NASA Budget as a percentage of Federal Outlays from 1966 to today. The graph tells the real story of why the first space age ended—and why the new one looks so different.
Ultimately, understanding the 1970s decline is the only way to avoid repeating the same mistakes as we head back to the lunar south pole. We can't just go for flags and footprints this time; we have to build something that stays.
