Tintin's Moon-Rocket

Readers in the US might not recognize the Tintin graphic novels, but everybody in Europe has read them. This nuclear powered rocket was quite well researched for the time. The main engine is apparently a NERVA style solid nuclear thermal rocket fueled with plutonium. The launch site has a breeder reactor used to cook uranium 238 into plutonium for fuel rods. The rocket lifts off and lands with an auxillary chemical rocket fueled by nitric acid and aniline, so as to prevent contaminating the ground with radiation.

The authors of the indispensable Spaceship Handbook did find one minor mistake. The astronauts lie prone on their acceleration couches, which is pretty much the worst position possible (second only to standing on their heads).

The authors of the Spaceship Handbook suggests that this was due to Mr. Rémy misinterpreting the diagram of the Werner von Braun moonship. In that diagram, the crew members who need to monitor the chart recorder are prone, but everybody in their acceleration stations are properly on their backs.

Anyway this is a minor flaw in a design that gets it right.

Exploring the Moon by Rocket Ship

Venus Rocket

Winged Interplanetary Spacecraft

Not too scientifically plausible spacecraft design, featured in a children's magazine. Not surprisingly it has the "Confusing-a-spaceship-with-an-airbus" fallacy. See the tiny "unmanned scout" on the ship's back? Its a remotely piloted reconnaissance drone. Isn't it cute?

Space Scout

RocketCat sez

Oh, I remember studying this ship when I was a kitten, in the poster hanging on my wall. The poster was based on work from Frank Tinsley, one of the gods of spaceship art. It does have a couple of questionable design decisions, but the blasted thing is more scientifically accurate than 99% of media science fiction. There is nothing quite as mentally stimulating as a good cut-away diagram. You can really put yourself in the picture.

This is from a book entitled The Answer to the Space Flight Challenge by Frank Tinsley (1958).

Noted rocket engineer G. Harry Stine designed this vehicle in the early 1950's. He figured that manned space stations would be controlled by the nation that built them. Therefore a scientific station could be instantly transformed into a martial moon at the sound of a trumpet! Horrors! Armed with atomic missiles, they could strike any spot on Earth. What a hideous threat to freedom and democracy the world over.

The space scout is designed to deal with this menace, blowing up hostile stations with atomic missiles before they can strike. Without it, the world stands unarmed and helpless before the threats of a technologically advanced dictator.

At least according to Mr. Stine. In reality it would probably be far more cost effective to just launch flight after flight of surface-to-orbit missiles until the evil space station was vaporized.

The spacecraft flies nose first in space, driven by the liquid fuel rocket engine. It flies tail first in the air, driven by the three jet engines. This means that the jet engine exhaust goes "upward", that is, in the opposite direction of the rocket exhaust.

The jet engines are mounted on "M" shaped supersonic wings fitted with conventional airplane control surfaces. Note that the control surfaces are on the upper edge of the wing, not the lower. The elongated nose cone of each jet engine doubles as a landing leg. Velbor points out that this is a poor design decision. A hard landing will transmit shock directly to the delicate mechanism of the jet engine turbines. They may explosively delaminate, shooting turbine blades at everything in line with the turbine plane. Which you may have noticed includes the fuel tanks.

The tail of the spacecraft is bulbous to increase the heat radiating surface area, and corrugated with liquid oxygen cooling pipes. In other words it is trying to do the same job as the heat shield on the base of the Apollo command module.

The three transparent blisters on the flight deck help the pilot to land by providing full ground visibility via a system of reflecting mirrors.

With the three man crew, two are always on duty while the third sleeps. In combat conditions all three are on duty. The craft is designed for a three-day mission, with a maximum life-support endurance of a week.

Mr. Stine later developed the design further into the "Mars Snooper." This added a petal like shields closing over the liquid fuel rocket engine bell during re-entry, and a more elongated passenger section. One difference is that this design uses a nuclear thermal rocket instead of a chemical one. The reactor also runs the jet engines, which are more like an air-fed nuclear ramjet. In 1971, the Estes model rocket company made a model rocket based on the Mars Snooper. My father had one. I always wondered why the tail fins were "M" shaped.


This nuclear-fueled reconnaissance craft is preparing to land on Mars' outermost satellite, Deimos — 12,500 miles away from the "red planet" (center) and 35 million miles away from the Earth.

Our spaceship is designed to fly in two directions—nose first as a space rocket and tail-first as a ramjet airplane. Propulsion for both is provided by a single atomic heat source, reacting with hydrogen for rocket thrust, and with atmosphere to power the ramjets.

As the ship approaches the Earth's atmosphere, it assumes a tail-first attitude. The "petal doors" enclose the rocket nozzle, and the ship is transformed into a high speed, ramjet airplane with M-shaped wings. Control fins are located in the nose of the craft, near the crew's quarters.

From Mars Snooper American Bosch Arma, (1959)

Tinsley Photon Rocket

This is a design for a photon-drive spacecraft, boosted into orbit by a chemical rocket. Note that the designer is a tad unclear on the concept. The photon drive is fed gigawatts of electricty by the fusion reactor, while the poor ship relies upon a crude solar boiler for its internal power. Nowadays photon drives are considered impractical, due to their ridiculous power requirements (three hundred megawatts for one lousy Newton of thrust).

Discovery from 2001 A Space Odyssey

Blueprint Attempt

RocketCat sez

Ya gotta include the Discovery! Only the coolest movie spacecraft ever in the history of cinema. Blasted thing looks like it came from a NASA study or flew out of a Robert McCall painting (actually McCall did paint it afterwards). But this is to be expected from a ship designed by Sir Arthur C. Clarke himself. The only thing is lacks is heat radiators, but that's not Clarke's fault. He originally included them but was over-ruled by the art department.

In the blueprints above, it shows the command module as being in line with the centrifuge hub. This is incorrect, because it would force the command module windows to be along the sphere's equator. As you can see from the photos the windows are north of the equator.

Cyrille Castellant

In these blueprints by Cyrille Castellant, the command module is offset from the hub axis with a slanted corridor. However, the designer makes the pod bay warehouse vertical instead of horizontal.

Kiyoshi Hiura

This marvelous reconstruction is made by a talented CGI artist named Kiyoshi Hiura. Below is the Babelfish translation of the relevant blog post (from Japanese into Broken English) and a translation by Michael Bianco.

Babelfish translation

Looking “the traveling of movie, at 2001 outer space” internal constitution of the [deisukabari] number probably has just become how? Artificial gravity (centrifugal force) it stays and the residential area how probably has been settled somewhere? You think that with the person who had doubt it is many.

As for the design figure of the [deisukabari] number when it was abolished, with thing, as for accurate structure you do not understand in regrettable thing. Here the next rough information

  • As for sphere of head about diameter 12m
  • Artificial gravity (centrifugal force) it stays, as for diameter of the residential area about 10m
  • As for diameter of pod about 2m

With, it presumed the internal constitution of the [deisukabari] number from each scene of the movie and tried drawing up the CG model.

Bianco's translation

How in the heck is the inside of the Discovery "deisukabari" (as seen in 2001 A Space Odyssey) configured? Where and how is the artificial gravity (centrifugal force) crew quarters situated? I think a lot of people have these questions.

Unfortunately, the plans for the Discovery have been lost, so we don't know the exact configuration. Here are the basic facts:

  • The spherical bow/head of the ship has a diameter of about 12 meters
  • The artificial gravity (centrifugal force) crew quarters has a diameter of about 10 meters
  • The diameter of the pods are about 2 meters

I've conjectured on the internal configuration from these facts and from (watching) each scene of the film, and built this CG model.

Internal Configuration

It is the figure which was seen from port side.

Picture of the Discovery as seen from the port side.

There is artificial gravity staying residential area in the form which parallels to the structure of muffler condition of the sphere rear. There is an air lock and equipment and material retention room in the floor of the pod bay. The equipment and material retention room is installed somewhat slantingly. It is the room of 8 prisms which remove the exchange part of AE35 unit. There is an air lock in the kind of form which strikes with the equipment and material retention room slantingly. Bowman there is no helmet with is the room which jumps.

The artificial gravity crew quarters (light blue) lies along the scarf/muffler shape on the back half of the sphere [the author previously refers to the sphere module of the Discovery as a head; the scarf/muffler reference is apparently an extended metaphor, so a less literal but more accurate translation translation might be: ...crew quarters lies along/on the tapering neck at the rear of the sphere module]. On the pod bay floor are the airlock (dark blue) and the equipment storage room (green). The equipment storage room is set at a somewhat oblique angle. It is the octagonal room from which the crew retrieved the replacement AE35 unit. The airlock seems to run into the equipment storage room at an oblique angle. This is the room into which Bowman leapt without a helmet.

It is the figure which was seen from above. There is a room (in figure yellow) which, even the switch room it should call in rear of the cockpit there is a passage and an intersection section (purple) in that rear. In the intersection section the switch room, the passage from port, the passage to artificial gravity staying residential area and the passage to the control room of starboard lower part cross. Furthermore, there is also an entrance to the memory room of HAL in the switch room.

This is a picture of the Discovery as seen from above. Behind the cockpit, there is what we could call the switch room (pictured as yellow) (ed note: Switch room is labeled "HAL logic room" in blueprint above), and behind this is a corridor and hub [literally intersection room] (purple). The hub is where the switch room and port- side corridor, the corridor leading to the crew quarters, and the starboard-side leading to the control room intersect. (ed note: hub is labeled "central air lock" in blueprint above) There is also the hatch leading to Hal's Memory Room in the switch room. (ed note: Mr. Kiyoshi seems to think that there is a purple corridor parallel to the HAL logic room, I am unconvinced that it exists.)

It is the figure which was seen from starboard side.

This is a picture of the Discovery as seen from the starboard side.

There is the memory room of HAL in the starboard side cockpit floor. There is a control room in the pod bay floor. There is a ladder to the cockpit floor in the inner part of the control room.

On the starboard side is the cockpit floor with HAL's memory room (red) being on this same floor. The pod bay floor has the control room (ed note: labeled "Pod Bay Control Room" in blueprint above). Next to the control room is a ladder which leads to the cockpit floor (ed note: labeled "Main Ladder" in blueprint above).

Movement in the Film

Bowman perceiving to the pool aviator being let flow, tries probably to go to the pod bay from the cockpit. In the picture, the seat it stands, " gets off " the ladder to the port rear. (Because it is kind of picture where the front is after to rear it is shape which " it gets off ") (From port as for movement to starboard side in picture it does not appear)

When Bowman notices that Astronaut Poole is being swept out into space, he moves from the cockpit to the pod bay. As pictured, he stands up from his seat and descends a ladder that takes him portside and back. (The front [of the cockpit] appears to become up in this image, so going back/aft would appear as "going down"/"descending") (ed note: in other scense, the front of the cockpit is shown as "forwards" instead of "up". This is because unsophisticated movie audience cannot understand that rockets are not boats) (The move from port to starboard is not shown) (ed note: The CG artist seems to think that there is a purple corridor parallel to the HAL logic room, I am unconvinced that it exists. I think that Bowman simply flew down the center of the HAL logic room.)

With the following scene it gets off the ladder which is connected to the starboard control room. And it goes to the pod bay. (Because it is difficult to see, it abbreviated pod)

In the next scene, he is descending the ladder connected to the starboard side control room. Then, he proceeds to the pod bay. (The pods have been removed for clarity)

With the [ri] which is the [ku] of air lock thrust, Bowman who enters from the air lock goes through the pod bay, the ladder of the control room inner part rises entering the control room. It moves to the passage intersection section from the stairway.

As for when he enters the airlock (ed note: without a helmet), Bowman, after entering the airlock, crosses/traverses the pod bay, enters the pod control room, and then climbs the ladder next to the control room. From these steps [ladder], he goes to the hub (ed note: central air lock).

With the following scene from the passage intersection section it appears in the switch room, takes the key, keeps entering to the memory room of HAL.

In the next scene, we see the switch room (Hal logic room) from the hub (central air lock). Bowman takes a key and enters HAL's memory room.

Diameter in sphere of the head was designated as 12m, but really there is about 13m because with, you think. We want 12.5m at least. In addition, as for diameter of pod that you think whether it is not about 1.9m. When structure and artificial gravity (centrifugal force) of muffler condition of the neck it stays and the residential area will be by chance, there is a possibility of having relationship. Perhaps it is settled in the muffler section. Structure of the passage intersection section it continues to be puzzle. Because the passage to artificial gravity staying residential area from the cockpit floor a little is below, the intersection section means to connect the mouth where height is different.

With movie “2010” as for the [deisukabari] number, the kind of revolution which turns over was done. This because revolution of artificial gravity staying residential area stops, is assumed that it is something due to the moment. But, how seeing, the fact that arranging artificial gravity staying residential area in such direction means you think that it is not possible. The top of the cockpit is unreasonable and, also between of the cockpit and the pod bay and under pod [be] [i] are unreasonable.

The front sphere's diameter was made to be 12m, but in fact I think it is about 13 meters. At the very least, we want to be 12.5m. Also, I'm thinking 'Shouldn't the diameter of the pods be about 1.9m instead of 2m' ? It is possible that the connection/relationship between the scarf shaped structure at the neck [of the forward module] and the crew quarters is incidental (ed note: it is unclear if the centrifuge is located in the scarf by chance or by design). It may or may not be situated in/on the scarf-like part. The configuration of the hub remains a mystery. The corridor to the artificial gravity crew quarters is a little below the floor of the cockpit, so the hub would be connected to corridors and hatches set at different heights (ed note: The centrifuge corridor has to be centered on the long axis of the Discovery, which is a little below the level of the cockpit deck. The hub will have to accomodate this. In the Castellant blueprint, the hub and the centrifuge corridor are connected by a sloping passage.)

In the movie 2010, the Discovery is rotating in a head-over-heels/somersault manner. This would entail having to stop the rotation of the artificial gravity crew quarters. However, which ever way you look at it, I think it would be impossible to use the artificial gravity crew quarters with this sort of orientation. Moving up out of the cockpit, moving between the cockpit and pod bay, and going down into the pod bay would all likewise be impossible. (ed note: I believe that Mr. Kiyoshi misunderstands. In 2010, the somersault motion of the Discovery is not by design. He is correct that it would make movement through the ship to be impossible. According to the novel, the Discovery is turning head-over-heels because the centrifuge has come to a halt and transfered its angular momentum to the entire ship. However, having said that, it seems to me that would make the ship spin on its long axis, not somersaulting.)

The Comet

The Comet from the Captain Future novels of Edmund Hamiltion is about as scientific as Flash Gordon. The idea of a space pilot pressing their foot on a cyclotron pedal like the accelerator on an automobile is sightly comical. And the electroscope is needed to follow hostile spacecraft by their rocket trail, since apparently nobody had invented radar. But the novels do have an almost "Star Wars" like charm.

The Comet

NO account of the Futuremen would be complete without a description of their famous space ship, the Comet.

This craft is the fastest ship in space. It can go where no other vessel would dare go, and contains within its compact interior full equipment for almost any emergency. It is, in fact, the flying laboratory of Captain Future and his comrades.

The Comet was built on the Moon by Curt Newton and the Futuremen. Into it, they put all their unparalleled scientific knowledge and skill. As a result, no ship in the System can outrival the Comet.

The hull is of an odd shape, like that of an elongated tear drop. This streamlined design was adopted because it combats air-resistance perfectly. Of course, there is no air-resistance in empty space. But streamlined construction makes for efficiency when cleaving through the atmosphere of a planet.

The hull is made with triple-sealed walls, each wall composed of a secret alloy devised by Curt and the Brain for special lightness and strength. The space between the walls is packed with a super-insulation. Thus the Comet can resist temperatures that would destroy an ordinary ship. Of course, when it ventures into extreme heat like that of the solar corona, it has to be protected by its "halo" of screening radiation.

The power-plant of the Comet consists of nine cyclotrons of unusual design. The cyclotrons are the heart of any space ship. They convert powdered mineral fuel into raving energy, by atomic disintegration.

The process is started by a switch which releases a powerful flash of force from a condenser into the cycs. After that, it is self-continuous, a small fraction of the generated power being constantly "fed back" into the cycs to keep up the process of atomic disintegration.

The main flood of terrific atomic energy flows through the control valves into the various rocket-tubes of the ship, as directed by the pilot. If the energy is blasted out of the tail rocket-tubes, it hurls the ship straight forward. If directed into the bow or braking tubes, it slows down the craft. If turned into the lateral tubes along the aide of the ship, or the top tubes in the upper side or the keel tubes in the lower, it pushes the ship up or down or to one side.


The Comet owes its unrivaled speed to the fact that its massive cyclotrons are of such radical design that they can produce an unprecedented output of atomic power. These cycs are one of the greatest inventive achievements of Captain Future.

The control of the Comet is essentially much like that of any space ship. The pilot sits in his chair, the main control panel In front of him. Above, easily in view, is the broad space window.

Between the pilot's knees is the space-stick and under his feet are two pedals.

The space-stick is important. It Is a device to control the flow of the atomic power into the various rocket-tubes at will, without the necessity of opening or closing the individual throttle of each tube. Such individual throttles are on the control panel for delicate maneuvering and special uses, but the space-stick is in use most of the time.

When the space-stick is in upright position, all the power of the cyclotrons is directed out of the tail-tubes, flinging the ship straight ahead. But when you pull the space-stick back toward you, it cuts some of the power into the rear keel tubes, with the result that the ship zooms upward in space. Similarly, when you push the space-stick forward, some of the power is cut into the rear top rocket-tubes, which sends the ship diving downward. The farther forward you push the stick, the more power goes into the top tubes, and the steeper is your dive. Moving the stick sideward cuts power into the right or left lateral tubes and turns your ship to right or left.

Under the pilot's right foot is the "cyc-pedal." This controls the amount of energy produced by the cyclotrons by regulating the flow of powdered mineral fuel into the cycs. When you want their full output, you push the cyc-pedal to the floor. When you want to cut the power off, you let the cyc-pedal come clear back.

Thus, when you get warning of a meteor close ahead and want to zoom up sharply, you do two things simultaneously — you pull the space-stick sharply back, so that the power flows to the tail and rear keel rocket-tubes, and you push in hard on the cyc-pedal.

The pilot has beneath his left foot the brake-blast pedal. When this is pushed inward. It instantly directs the atomic energy of the cyclotrons into the bow or brake-tubes which project from the ship's bow for a few inches. Just beneath the fore window. Pushing in on the brake-blast pedal automatically cuts out all other tubes. To make a quick stop, you simply jam both brake-blast and cyc-pedals to the floor, which pours all the power of the cycs into a blast ahead.

These standard principles of space ship control are used by Captain Future and his companions in the Comet. They are all such consummate pilots, however, that they often ignore the convenience of the space-stick and use the individual rocket-throttles, to cut a course as close as possible.


The control panel of any space ship is a bewildering sight. But that of the Comet would baffle any ordinary pilot, even if he were of Rocketeer rating. All the ordinary instruments of space navigation are on the Comet's panel — the meteorometers that warn of distance and direction of nearby meteors, the gravitometers that indicate the pull of all bodies in space, the ether-drift indicators and main cyc-switch and auxiliary televisor screen and microphone. But also, the Comet has on its panel a variety of unusual instruments.

There's the atmosphere-tester, an ingenious device of Captain Future which automatically takes in and analyzes a sample of any air. and shows the percentage of all elements in it. There's the comet-camouflage switch. When turned on, it actuates a mechanism which ejects a cloud of shining ions from all rocket-tubes, concealing the Comet and making it look like a small real comet with long, glowing tail.

There's the electroscope, one of the Brain's pet instruments, and which has done sterling service in tracking criminals in space. It's a device that can detect a recent rocket-trail of a ship in space, by the faint trail of ions always left in a rocket-discharge.

The two space chairs that flank the pilot's chair in the control room of the Comet are so mounted that their occupants can handle the two proton guns of heavy caliber which project through the walls of the ship. These weapons fire a flash of energy of unequaled range and intensity.

The main cabin of the Comet is not built for comfort. Two folding bunks in one comer are the only sleeping provisions. For neither the Brain nor Crag require any sleep, and Otho doesn't need much. Food and other perishable articles are carried in a cold-storage compartment sealed off from the rest of the cabin, and open to the bitter cold of space.

Everything in the cabin is subordinated to scientific requirements. In one corner is the powerful main televisor set, the compact atomic motor generators which can furnish auxiliary power for any undertaking, and the locker of atomic tools of all descriptions.

In an opposite corner is the compact astronomical observatory of the ship. There is a battery of electro-telescopes and electro-spectroscopes of high power. These instruments have their light-gathering lenses mounted outside the hull of the ship, and are controllable from inside so that they can be directed at any celestial object.

Light that falls on the lenses is transformed into electricity by a unique photoelectric cell, led in through a cable inside, and amplified and transformed back into a vastly magnified image. Adjacent to these instruments is a file of spectra of every planet, star and other body of importance, and there is also a collection of atmosphere samples from every world and moon in the System.

The chemical laboratory of the Comet is a concentrated mass of apparatus whose application has enabled the scientific wizard and his companions to perform those alchemical feats which have astounded the System. Beside it is the reference library, composed of every important reference and scientific book, reduced to micro-film form.

There is also a botanical cabinet, with specimens of rare plants and vegetable drugs from faraway planets; a surgical and biological corner with a folding operating-table and instruments that have often worked strange magic. There are other cabinets of instruments and specimens and materials too numerous to list.


In one side of the ship is the air-lock entrance. It is automatic. When the outer door is opened, the inner door automatically closes. if it is not already closed. Inside the little lock-chamber is a cabinet containing space-suits, impellers, and similar equipment.

The Comet has many other unique features. Its rocket-tubes, for instance, have special check-valves which make It possible for them to operate efficiently under water. Thus the Comet can be used as a submarine in case of emergency. Its cyclotrons are so designed that they use infinitely less powdered mineral fuel than is usual, and the mineral tanks beneath the deck which hold the supply are sufficient for extraordinarily long continuous operation.

The Comet has been in almost every comer of the Solar System. Strange beings in unknown depths of remote worlds have seen the tear-drop ship plunging across the sky, and people of the greatest civilized cities on the nine worlds have cried out in excitement as they glimpsed it zooming toward the stars. For, all over the System, the Comet is known and recognized, and those who see it know always that the Futuremen are out on the space-trail.
