“From the pages of Jules Verne to a modern-day mission to the moon, a brand new chapter of our exploration of our celestial neighbor is full.” So stated NASA commentator Rob Navias as Artemis 2’s Integrity spacecraft landed safely within the Pacific this previous April.
It’s putting simply how related the mission profile of Artemis 2 was to the journey described by the French writer within the mid-Nineteenth century. At a time when his friends have been writing about fanciful balloon journeys to different planets, Jules Verne dealt realistically with escape velocity, orbital slingshots, and course-correction burns. Sure, he made errors — a few of them laughably apparent to the trendy reader — however many facets of his tales have been eerily prescient of the true area missions that have been nonetheless a century or extra away.
Usually known as the daddy of science fiction, the prolific Verne wrote of extraordinary voyages on modes of transport that didn’t but exist, just like the submarine in “Twenty Thousand Leagues Underneath the Sea”, and took readers to unexplored areas, resembling “Journey to the Middle of the Earth”.
Verne’s fourth novel, “From the Earth to the Moon”, was printed in 1865. Its darkly comedian opening chapters describe how the members of the Baltimore Gun Membership discover their ballistic skills surplus to necessities on the conclusion of the American Civil Struggle (a battle nonetheless ongoing as Verne wrote). Membership president Impey Barbicane proposes a brand new outlet for his or her expertise: “I started to wonder if, with a sufficiently massive cannon, it is perhaps attainable to shoot a projectile to the moon.”
Verne was obsessive about details and figures. He explains the mathematics and science of Barbicane’s 900 ft (274 m) cannon, or “Columbiad”, in nice element, together with the trajectory of its projectile.
His reasoning about the place to find the Columbiad was sound sufficient to be replicated by NASA a long time later: launch from as near the equator as attainable to get a pace increase from the Earth’s rotation. Verne picked a spot close to Fort Myers, on the other facet of the Floridian peninsula to Cape Canaveral, however at a really related latitude.

As “From the Earth to the Moon” proceeds, French adventurer Michael Ardan volunteers to man the Columbiad’s hole projectile. Barbicane and his nemesis, Captain Nicholl, quickly agree to hitch him.
However right here we hit the primary main drawback in Verne’s imaginative and prescient. Not like a rocket, which accelerates to flee velocity over a couple of minutes, subjecting its crew to sturdy however survivable g-forces, a projectile fired from a cannon accelerates nearly instantaneously. Barbicane, Nicholl, and Ardan would have been crushed to a paste.
Nonetheless, the fictional launch is profitable, and “All Across the Moon”, printed 4 years later in 1869, picks up the story. As a substitute of hitting the moon, as Barbicane had fairly recklessly supposed, the projectile seems to be on a free-return trajectory, taking it across the far facet of our pure satellite tv for pc.
A few of the sequel’s particulars are charmingly naive. Though Verne equips his vacationers with chemical equipment to provide oxygen and scrub carbon dioxide, he has no qualms about them opening portholes on a number of events, so long as they’re fast! His projectile’s inside is spacious and richly appointed like a Victorian research, and its occupants get pleasure from gourmand meals with nice wines, a far cry from the rehydrated rations that Reid Wiseman and company munched on during Artemis 2.
Verne also has his crew mostly bound to the capsule’s floor by gravity. He mistakenly has them experience weightlessness only at the “neutral point”, the spot where the Earth’s and moon’s gravitational pulls are equally balanced. Still, it is quite amazing to read zero g imagined at a time when it was completely beyond all human experience (except perhaps briefly, if one of the recently invented “safety elevators” failed).

Like the crew of Artemis 2, Barbicane, Nicholl, and Ardan eagerly observe the lunar surface during their journey. Describing their observations, Verne stuck mostly to real earthbound observations, which he’d meticulously researched in the libraries of Paris. But as his crew swings around the far side of the moon, “enveloped in a veil of darkness the most profound”, they catch a distant glimpse of a fiery light.
This evocative flicker in the vast blackness of lunar night must have been just what Wiseman and co experienced when they saw micrometeor impacts on the dark side of the moon. Those who watched the Artemis 2 broadcast may remember the team in the Science Evaluation Room (SER) literally jumping for joy when the astronauts reported seeing these flashes.

In line with the science of his time, which said that lunar craters were volcanic, Verne ascribes his flickering light to an eruption. But a couple of pages later, his capsule encounters a meteoroid which explodes nearby. “Thousands of glittering fragments were flying around them in all directions,” he writes, via Edward Roth’s translation. We can only imagine how the SER would have reacted to that!
As the fictional capsule approaches the point of neutral gravity for the second time, the crew fears getting stuck there. In another farsighted plot point, Verne has his characters attempt a course-correction burn using firework-like rockets. The burn fails, but the capsule has just enough inertia to be drawn to Earth once again.
Barbicane, Nicholl, and Ardan splash down in the Pacific – again somehow surviving a massive shock, since their capsule has no parachutes – and are eventually recovered by the US Navy, much like the Apollo and Artemis crews. The closing chapters of “All Around the Moon” see the trio paraded victoriously through the streets all over America, in a final foreshadowing of real lunar missions.

“A hundred years ago, Jules Verne wrote a book about a voyage to the moon,” said Neil Armstrong during Apollo 11’s homeward flight in 1969. “His spaceship, Columbia [sic], took off from Florida and landed in the Pacific Ocean after completing a trip to the moon.”
Nearly 60 years later, and 160 years after their first publication, the imaginative spaceflights of Jules Verne continue to echo humanity’s real missions to our nearest neighbor.
