Jules Verne Didn't Predict Apollo 11 — He Had a Mathematician Check His Work
From the Columbiad cannon to the Saturn V to the SLS: one fictional template, three eras of engineering.

The Short Version
- The famous list of Verne’s “predictions” — three crew, Florida, Pacific splashdown — is real, and it is the least interesting part of the story.
- The flight time printed on his 1865 title page lands within about five and a half hours of Apollo 11’s actual run from launchpad to lunar surface. That number is where the argument starts.
- One of the most-repeated “predictions” runs backward: Apollo borrowed a name from Verne, not the reverse.
- Artemis II flew a version of the same profile in April 2026 — including a trajectory Verne put in print in 1869.
Growing up in the mid-1970s, I read Jules Verne before I read almost anything else. His novels were from the 1860s, which already seemed impossibly old to a kid, and yet they didn't feel that way. The Nautilus, Around the World in Eighty Days — there was a pull to them, like something trying to be real rather than just entertaining. Then there's the other kind of science fiction: Mars Attacks!, Tim Burton's 1996 film with Jack Nicholson squaring off against rubber-suited Martians. Great movie. Gloriously ridiculous. Nobody is calling Tim Burton a prophet.
That gap is what this post is actually about. Verne's 1865 novel From the Earth to the Moon turned out to be eerily accurate — in crew size, launch location, transit time, and splashdown method — when compared to the real Apollo 11 mission a century later. He wasn't the only writer to reach for the stars before rockets existed — Cyrano de Bergerac imagined rocket-powered flight two centuries earlier — but Verne is the one engineers still talk about. And in April 2026, with Artemis II carrying a crew around the Moon for the first time in over half a century, the comparison feels more alive than ever. If you want to understand why a piece of 19th-century fiction still comes up in conversations about 21st-century space programs, this is the comparison to make.
What Jules Verne Got Right About the Apollo 11 Moon Landing
The standard list is easy to assemble, and you have probably seen it. Verne's fictional projectile carries three passengers; Apollo 11 carried Neil Armstrong, Buzz Aldrin, and Michael Collins. His "Columbiad" cannon is built near Tampa; Apollo 11 launched from Cape Canaveral, about 130 miles away across the same peninsula — and Verne chose that latitude deliberately, understanding that a launch closer to the equator costs less energy. The novel even stages a rivalry between a Florida site and a Texas site, a competition the 20th century went on to run for real. In the book the capsule comes down in the Pacific and a U.S. Navy ship collects it; Apollo 11's Command Module was pulled from the Pacific by USS Hornet on July 24, 1969. The vehicle itself — conical, metallic, crewed, pressurized — is recognizably the shape NASA eventually built.
Fine. Now here is the number nobody bothers to check.
Verne put the flight time in the title. The full subtitle is Direct in 97 Hours, 20 Minutes — a specific figure, committed to print in 1865, before a single rocket had left the ground. Apollo 11 lifted off at 13:32:00 UTC on July 16, 1969, and Eagle touched down in the Sea of Tranquility at 20:17:39 UTC on July 20. Subtract one from the other and you get 102 hours, 45 minutes, and 39 seconds.
Verne was short by five hours and twenty-six minutes. Against a four-day journey, that is an error of about five percent.
A word about which clock I'm using, because it matters. Apollo 11 reached lunar orbit earlier, at roughly 76 hours into the flight, and if you measure to that point Verne looks worse. But Verne's projectile was aimed at the Moon itself, not at an orbit around it — his passengers expected to arrive, not to circle. Launch to touchdown is the comparison that matches what he was actually describing. Most retellings skip this entirely and round the whole thing off to "about three days," which quietly throws away the most impressive thing in the book.
Jules Verne vs Apollo 11: Side-by-Side Comparison
| Detail | Jules Verne (1865) | Apollo 11 (1969) |
|---|---|---|
| Crew size | 3 passengers | 3 astronauts |
| Launch location | Near Tampa, Florida | Cape Canaveral, Florida |
| Flight time to the Moon | 97 h 20 min (stated in the title) | 102 h 46 min (launch to touchdown) |
| Splashdown ocean | Pacific Ocean | Pacific Ocean |
| Recovery vessel | U.S. Navy ship | USS Hornet (U.S. Navy) |
| Capsule shape | Conical, metallic | Conical Command Module |
| Launch mechanism | Giant cannon (Columbiad) | Saturn V rocket (staged) |
| Separate lander | None — single vehicle | Lunar Module Eagle |
| Moon environment | Possible life, Earth-like | Barren, airless, lifeless |
One row in that table deserves an asterisk that almost never gets attached to it. Verne's cannon is the Columbiad. Apollo 11's Command Module was Columbia. You will find that pairing near the top of nearly every "Verne predicted Apollo" article, presented as a fourth or fifth uncanny hit. It isn't one. The influence runs the other way — Verne is upstream of the naming, not a forecaster of it, and Armstrong himself made the connection explicit during the flight home, describing their spacecraft to a television audience as a modern counterpart to Verne's. That is a tribute, not a prophecy. Which raises the obvious question about the rest of the list: how much of it is Verne seeing the future, and how much is the future quoting Verne back at us?
Why Jules Verne's Moon Calculations Were Surprisingly Accurate
The five-hour answer isn't mysticism. Verne read the physics that already existed in 1865 — escape velocity, gravitational mechanics, trajectory planning — and pushed it further than anyone else was willing to in fiction. That's a different project from most science fiction, which invents a mechanism and handwaves the math. Edgar Allan Poe imagined life beyond Earth in his own way, but Verne built his speculation on numbers, and that is what made the difference.
The muzzle velocity he assigned his projectile — on the order of 11 km/s — sits strikingly close to the real escape velocity of about 11.2 km/s, a figure a novelist had no business landing on by intuition alone. He didn't intuit it. While writing the book, Verne had his calculations checked by his cousin Henri Garcet, a Paris professor of mathematics who had published a widely used astronomy textbook; Garcet's colleague, the mathematician Joseph Bertrand, reportedly helped as well. That quiet collaboration is why the transit time and the trajectory came out where they did. Modern Verne scholars — among them Arthur B. Evans, who has written extensively on Verne's scientific sources — have long emphasized that the grounding was deliberate rather than lucky: Verne built his fiction outward from the best physics his era could supply.
My own read — having spent decades with these novels — is that the "predictions" held up because Verne was doing something rare: using real constraints to build the fiction. The cannon was wrong, but the velocity was in the right neighborhood. The capsule shape was roughly right because the physics of re-entry and crew housing points you in similar directions regardless of era. A 1865 novelist who runs the arithmetic and gets within five percent of a mission flown a century later is not guessing. He is doing engineering with the wrong hardware — and the hardware is where it all comes apart.
The Columbiad to the SLS: the mechanism changed entirely. The destination didn't.
Where Jules Verne's Moon Prediction Was Wrong
Verne's launch mechanism is a cannon. A massive gun buried in the Florida earth, pointed at the Moon. A cannon delivers its entire acceleration in a single, near-instantaneous impulse. To escape Earth's gravity a vehicle needs to reach roughly 11.2 km/s — about 25,000 mph — and reaching it inside a blast lasting fractions of a second would subject passengers to tens of thousands of times their own body weight. Nobody survives that. Apollo used staged chemical rockets that build the same velocity gradually, over roughly eleven minutes to low Earth orbit. Verne had the destination and the arithmetic; the method was the exact opposite of what actually works.
There's also no separate landing module in his story. The projectile is one piece — it goes and it returns as the same object. Apollo 11 depended on splitting the vehicle in two: the Command Module Columbia holding lunar orbit with Michael Collins aboard, and the Lunar Module Eagle descending with Armstrong and Aldrin before climbing back up to rendezvous. That split was the technical core of the entire mission, and it is the single largest thing Verne never conceived of.
And the Moon itself. Verne allowed for possible inhabitants and a broadly Earth-like environment. Apollo found a barren, airless, geologically quiet world where surface temperatures swing between roughly 127°C in sunlight and -173°C in shadow. So when people call him a prophet, they are being generous with the word. He got the outline and several of the numbers. The engineering was mostly wrong — which is exactly what you would expect from someone extrapolating honestly from 1865 physics, and exactly what a prophet would not have gotten wrong.
Artemis 2026: The Moon Mission That Didn't End With Apollo
If Verne's fiction tracked Apollo this closely, what happens when you hold it up against a mission flown in our own decade? As of April 2026, that stopped being a thought experiment.
Artemis II launched on April 1, 2026, and on a mission NASA describes as nearly ten days long, four astronauts looped around the Moon and came home, splashing down in the Pacific about forty miles off San Diego on April 10. A U.S. Navy ship, USS John P. Murtha, took the crew aboard — fifty-seven years after USS Hornet did the same job, and 161 years after Verne wrote the scene. It was the first crewed voyage beyond low Earth orbit since Apollo 17 in 1972. The crew — NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, with Canadian Space Agency astronaut Jeremy Hansen — flew an Orion spacecraft they had named Integrity, and traveled farther from Earth than any humans before them, passing the record Apollo 13 set in 1970.
There is a detail in that flight profile worth pausing on. Artemis II did not brake into lunar orbit; it flew a free-return trajectory, swinging around the far side and letting the Moon's gravity sling it home. Verne wrote that trajectory too — not in the 1865 novel, but in its 1869 sequel, Around the Moon, where the projectile misses its target, loops the far side, and falls back toward Earth. He arrived at it as a plot problem. NASA arrived at it as a safety architecture, because a free-return path brings the crew home even if the engines never fire again. Same curve, opposite reasoning, a century apart.
What comes next looks nothing like his book. NASA's lunar strategy shifted hard at an agency event called Ignition on March 24, 2026, where Administrator Jared Isaacman announced a pause on the Gateway lunar-orbit station in its current form and a redirect toward a phased base on the surface — roughly $20 billion over about seven years, with Gateway hardware and international-partner contributions repurposed where feasible. The pivot was framed openly as a race against China's lunar timeline, and as a deliberate break from Apollo's pattern: this time the stated goal is to stay. Under the revised architecture, Artemis III — targeted for 2027 — is no longer a landing at all, but a low-Earth-orbit test in which Orion docks with one or both commercial landers, pushing the first crewed surface landing to Artemis IV around 2028. Those dates are still moving.
Honestly, I'm not sure Verne would recognize what Artemis is trying to build. His Gun Club funded a single spectacular shot and then went home. Artemis runs across multiple agencies and countries, with reusable landers, commercial partners, and multi-year surface campaigns — goals that are as much about logistics and geopolitics as about glory.
But one instinct of his held up better than the cannon did. In From the Earth to the Moon, the Moon is never quite the point; his characters are always looking past it. His sense that lunar exploration would carry political and economic weight, not just technical weight, maps reasonably well onto how Artemis is actually unfolding — even though the 19th-century nationalism of his Gun Club looks nothing like a multi-country program with commercial contractors. The social logic rhymes even where the technology doesn't.
Conclusion: Jules Verne Was Not a Prophet — He Was Something Rarer
Verne didn't predict the Moon landing. He did the math from the physics available to him, had a working mathematician check it, and extrapolated further than anyone else had bothered to. A century later, engineers built the mission and found several of his numbers already sitting in the right neighborhood — the crew of three, the Florida launch, the Pacific splashdown, and a flight time five and a half hours off the real thing. Not prophecy. The output of a writer who did the work.
I still read those novels — the ones from the 1860s. Not as predictions. As a particular kind of rigor that most fiction doesn't bother with, and that turns out to matter more than most fiction's imagination.
Jules Verne wasn't a prophet. He was something rarer — a writer who took physics seriously enough that engineers, a century later, found themselves building what he had already sketched, and naming it after him on the way. That's not mystical. It's better. The same impulse showed up in Leonardo da Vinci, centuries before Verne — people who drew futures they would never live to see.
