In this bi-weekly series reviewing classic science fiction and fantasy books, Alan Brown looks at the front lines and frontiers of the field; books about soldiers and spacers, scientists and engineers, explorers and adventurers. Stories full of what Shakespeare used to refer to as “alarums and excursions”: battles, chases, clashes, and the stuff of excitement.
I am a long-time fan of author Alan E. Nourse, whose works I discovered during my youth because the local library shelved them alphabetically beside books by Andre Norton. Unfortunately, my library only had three of Nourse’s books, so I have always been hungry to read more. One of the books I’ve searched for is the juvenile novel Trouble on Titan, set on Saturn’s largest moon—one of the most fascinating bodies in the Solar System. So, when I recently found a used paperback copy at a reasonable price online, I snapped it up.
The book turned out to be well worth the wait. The technological extrapolation is, as with many books from the mid-20th century, significantly at odds with what has actually happened in the ensuing decades. And our understanding of the nature of Titan, as with many other bodies in the outer Solar System, has evolved quite a bit from the theories and suppositions of that time. But despite the setting being dated, the story is an engaging tale of two young men from vastly different backgrounds, one from Earth and one from Titan, whose unlikely friendship prevents a violent and unnecessary clash. There is also a clever twist that keeps this story of colonial uprising from being just another futuristic rehash of the American Revolution.
Trouble on Titan was originally published by the John C. Winston Company in 1954. The copy I used for this review is a used copy, published by Ace Books in 1986. The cover is a striking astronomical illustration of Titan, Saturn, and a spaceship, painted by Don Dixon. There is a stamp on the flyleaf showing that it was once in stock at Cal’s Paperback Exchange in Spokane, Washington.
About the Author
Alan E. Nourse (1928-1992) was a physician who also had a long and productive writing career. He wrote science fiction, mainstream fiction, non-fiction books on science and medical issues, and penned a medical column that appeared in Good Housekeeping magazine. I previously reviewed his novel Raiders from the Rings, his short story collection Tiger by the Tail, and his novel Star Surgeon. There is more information on the author and his work in those reviews. Like many authors of his time, some of his work is out of copyright and available for reading on the internet for free here on Project Gutenberg.
Titan Is Cool
Saturn’s moon Titan is one of the coolest bodies in the Solar System, and that’s not just because of its low surface temperature, which is about 291 degrees below zero Fahrenheit. It has many other qualities that make it unique. Unlike other moons, it has a thick atmosphere, and even lakes and oceans. That atmosphere, however, is a mix of nitrogen and methane, and because of the low temperatures, the lakes and oceans are made up of methane and/or ethane. It is not a rocky body, although it does have a rocky core, and is made up mostly of ice, with an icy crust, and a possible subsurface ocean of liquid, ammonia-rich water. Its atmosphere is perpetually cloudy, and it has seasonal weather patterns, and even rain (although the precipitation is not water). It is believed to have constant, strong winds, with the atmosphere rotating at a different speed than the surface, something called atmospheric super-rotation. There might be some volcanic activity on Titan, but it would likely consist of eruptions of liquid water instead of liquid rock. Like Earth’s Moon, Titan is tidally locked to Saturn, so if you could see Saturn through the hazy atmosphere, it would always be in the same position.
I have long been fascinated by Titan, because while it seems Earth-like in some aspects, it is strange in other ways. For example, because of its low surface gravity and thick atmosphere, it might be the only place in the Solar System where a human could strap on a set of wings and be able to fly simply using the strength of their arms. Because of Titan’s low temperatures, the nature of materials is quite different from what you find on Earth, as what is gas on Earth is liquid on Titan, and Earth liquids are solids. That difference would pose significant challenges to visitors from Earth, who require temperatures to survive that would melt their surroundings on Titan, and who require oxygen, a dangerously explosive substance on Titan. And unlike current spacesuits, which are insulated from their surroundings by the vacuum of space, protective suits on Titan would have to be adapted to a thick atmosphere that would draw heat away from the occupants.
While Alan E. Nourse’s Trouble on Titan does a fairly good job conforming to scientific ideas about Titan as they existed in the 1950s, it does feature some details that we now know are incorrect. The first is the sky, which is described as clear and blue, providing a good view of Saturn. And the second is the rocky surface. This matches the view of Titan from the period when astronomical artist Chesley Bonestell produced his famous painting “Saturn as Seen from Titan,” which shows a crisp view of the planet, with its rings seen nearly edge-on, low above a row of jagged peaks rising from a snowy plain. But we now know that Titan is shrouded with clouds and the surface is icy, with little volcanic activity, and smoothed by the energetic weather conditions.
Nourse depicts his colonists living under a Plexiglas dome, but while that acrylic material might be synthesized from local components on hydrocarbon-rich Titan, Plexiglas becomes quite brittle at extremely low temperatures, and I doubt it would work as an effective barrier between the frigid outer atmosphere and the much warmer atmosphere breathable by humans. Nourse has the colony formed around the mining of the mineral ruthenium, which is vital to the technology of converting solar energy to broadcasted power (that mineral does exist, and has some unique electrical properties, but the properties Nourse attributes to it here involve a bit of artistic license). Moreover, the mineral is gathered from tunnels through rock, which are filled with an oxygen-based atmosphere the miners can breathe. But not only would the presence of that element be unlikely in the icy surface material on Titan, keeping tunnels warm enough for humans to work and breath in would probably cause melting and collapse.
One thing Nourse describes accurately is the jet aircraft built by one of the characters. Unlike jets on Earth, which gather oxygen from the atmosphere to mix with hydrocarbon-based fuels, a jet on Titan would gather hydrocarbons from the atmosphere to mix with oxygen carried as fuel. And welding would be different as well, as you wouldn’t need acetylene for the torch, just oxygen released into the atmosphere. These are perfect examples of the topsy-turvy conditions that make Titan one of the coolest bodies in the Solar System.
Trouble on Titan
Perhaps because the book is intended for younger readers, Nourse begins with a preface explaining some of the unique conditions of Titan, and the challenges of traveling in space. When the narrative starts, it is from the viewpoint of young Tucker Benedict, who has just graduated from high school in Denver and is traveling home to New York by jet. In his pocket, he has an acceptance letter and scholarship offer from the Polytechnic Institute of Earth. The stewardess gives him a telegram received just after they departed. He is delighted to find it is from his father, a Colonel in the Security Commission, who has returned early from a mission on Mars and will meet him in New York. The two of them are quite close, as his father raised him alone after Tucker’s mother died while he was young, although as Tucker has gotten older, his father has spent more and more time away on missions around the Solar System.
Tucker then spends some time musing about the world he lives in, where solar power is gathered by massive solar energy converters, and then beamed to buildings, vehicles, and devices all around the planet. This energy conversion process is made possible by the mineral ruthenium, which comes from a mining colony on the moon Titan. But Tucker is not interested in this technology, because his passion is space travel, where he wants to make a career.
When Tucker tells his father news of his scholarship, though, he doesn’t get the reaction he expected. His father is proud, but subdued. It turns out he had hoped to take Tucker to Titan on his next mission, but it’s a long journey, and Tucker cannot accompany him and accept the scholarship. There is unrest at the mining colony, which the Colonel must investigate. Titan was originally a penal colony, and while the original convicts are long dead, the miners have a reputation for being unreliable and difficult.
The Colonel has to visit his office, so Tucker returns to their apartment and begins opening mail. There is a strange letter addressed to his father, purportedly from him…one Tucker didn’t send. Rather than open it with the pull tab, Tucker slices it open with a razor, and finds it contains a slab of incendiary material, which he neutralizes by soaking it in water. He realizes that someone wants to kill his father, probably to prevent him from investigating the situation on Titan. And Tucker decides he must put aside his scholarship for now and travel to Titan with his father in order to protect him. He decides to keep the assassination attempt a secret for now, as his father might not want him along if he knew of the danger. (That struck me as an incredibly poor decision, but Tucker is young and naïve, so it fits the character.)
The narrative largely skips over their two-month journey to Titan, although during the trip, Tucker does tell his father about the letter-bomb. The idea of an assassination attempt does not surprise his father, as there have been mysterious disappearances of large amounts of supplies and materials on Titan, implying a conspiracy of some sort.
They land near the colony, and a half-track vehicle arrives to meet them. It is the elected head of the mining colony, Anson Torm. He bluntly tells the Colonel that unless the government offers some concessions to the miners, the Earth may have seen its last shipment of ruthenium. Torm is not threatening, just warning that he is losing control of the colony, and an uprising may be imminent. The Colonel is angered, and the two retreat to a cabin for a heated discussion. Tucker takes the opportunity to don a suit and explore the surface, but returns to the ship when someone arrives on a crudely built jet plane. It is Torm’s son, David, who warns that a troublemaker at the colony, Cortell, is taking advantage of Torm’s absence to cause problems.
The Colonel, Torm, and Tucker head back to the colony in the half-track. David takes off, and begins to crisscross their path at low altitude. It turns out he is concerned about a possible explosive device, and for good reason, because during one of the passes, there is a large explosion, and his jet slides to a rough landing. The others pick him up, and Torm immediately identifies Cortell as the person who must be behind the murder attempt.
They go to the colony, and while the fathers continue their discussions, David takes Tucker on a tour of the colony. Nourse uses this as an opportunity to show the reader what the colony and mining operation are like, and does so smoothly, without the information feeling like an expository lump. It turns out that the two young men are both interested in space travel and rocketry, and they begin to form a friendship. The two of them begin to overcome the prejudice that has built up between the mining colony and Earth over many decades. And this new friendship is strong enough for David to reveal that, while he doesn’t know all the details, the colony is harboring something called The Big Secret, which is the reason for the disappearing supplies the Colonel is investigating.
What follows is an exciting tale. There is political upheaval, violence, a desperate drive across Titan in a half-track, and the rushed repair of David’s jet to use in the search for The Big Secret, and to uncover the extent of Cortell’s plot. I can’t reveal much more without spoiling the surprise twist of the ending, but will only say that it is a satisfying conclusion, and an exciting ride to get there. The nature of The Big Secret keeps this book from being yet another book replaying the American Revolution in a futuristic setting.
Final Thoughts
I’m glad I finally got to read Trouble on Titan, because it turns out to be the best thing I’ve ever read from Alan E. Nourse. The characters are well drawn, Titan is a fascinating setting, and there is plenty of action and adventure to keep the reader turning pages. Nourse delivers a nice twist at the end that is well executed—hinted at as the story progresses without being telegraphed too explicitly in advance. And the friendship between Tucker and David, and their relationship with their fathers, gives the story a strong and satisfying emotional core. There are some dated elements, but this is a story that has held up pretty well in the decades since it was written.
And now I’d enjoy hearing your thoughts, either on Trouble on Titan specifically, or Alan E. Nourse’s work in general. And if you have any other books about the fascinating moon Titan to recommend, I’d love to hear about them.[end-mark]
