10 Compelling Generation Ship Books That Take You on a Journey

Say goodbye to Earth. 

compelling generation ship books

Colonizing distant planets and exploring the galaxy have long been common themes in sci-fi. And it stands to reason that the question of how such journeys would unfold, and how they would impact explorers, have also proved fertile ground for the genre. 

Enter the generation ship, a vessel that could ferry humanity on voyages that take millennia. How would our species survive on massive ships the size of cities? What changes would each generation experience as they move further and further from memories of terrestrial life? 

The generation ship genre—which marries hard sci-fi and societal commentary —has produced some of science fiction's most thought-provoking and powerful works. These are a few of our favorite generation ship books. 

orphans of the sky

Orphans of the Sky

By Robert A. Heinlein

As one of the earliest examples of what would become the generation ship genre, Heinlein’s Orphans of the Sky continues to reverberate. 

Originally published as two novellas in 1941, Orphans of the Sky was released as a single novel in 1961. It centers around a ship called the Vanguard. 

The original crew was killed in a mutiny centuries before the events of the novel. In the intervening years, the descendants of the ship’s survivors have lived for entire generations without the knowledge that they are on a massive spacecraft. 

When one man discovers this secret, he sets on a path that will forever change society as he knows it.

Non-Stop

Non-Stop

By Brian W. Aldiss

Non-Stop, from Grand Master of Science Fiction Brian W. Aldiss, is a foundational entry in the generation ship genre. 

Originally published in 1958 as a kind of response to Robert Heinlein’s Orphans of the Sky, Non-Stop follows a group of humans who toil away their existence in jungle-like corridors.

 When a man named Roy Complain and a few others begin to suspect they are actually on a massive starship, they set out to find the truth. With its breakneck pacing and shocking ending, Non-Stop is a fascinating take on the genre. 

Rendezvous with Rama

Rendezvous with Rama

By Arthur C. Clarke

When a gargantuan cylindrical object enters Earth’s orbit, a group of astronauts disembark to investigate. 

What they discover is a massive starship filled with seemingly inaccessible buildings, a sea, and odd machine/animal hybrids. The one thing missing? Whatever mysterious civilization once inhabited the ship. 

Rendezvous with Rama won multiple awards including the Hugo and Nebula, and is generally considered one of Arthur C. Clarke’s finest novels.

Eon

By Greg Bear

This mind-bending novel from Nebula and Hugo Award–winner Greg Bear centers around the mystery of a three hundred kilometer-long asteroid that appears in Earth’s orbit. 

It's soon discovered that the asteroid is actually a hollowed, terraformed spacecraft that once housed the human survivors of a nuclear disaster—one that occurred more than a thousand years in the future. 

When theoretical mathematician Patricia Vasquez enters the ship, she discovers a tunnel existing beyond the dimensions of the vessel, one that leads to a stunning future which holds the key to humanity’s survival.

Ship of Fools

By Richard Paul Russo

The Argonos has been drifting throughout the galaxy for hundreds of years, searching out signs of life. Entire generations of humans have only known life aboard the massive starship. 

When the ship’s sensors pick up a mysterious transmission from a nearby planet, the ship’s crew discover the horrifying remains of the planet’s colonists. 

When another mysterious signal calls to their ship, the Argonos has to investigate—but is it a benign transmission, or something more sinister luring them in?

dust

Dust

By Elizabeth Bear

Dust, the first in Elizabeth Bear’s Jacob’s Ladder series, mashes up fantasy and hard science fiction to put a new sheen on generation ship tropes. 

The novel centers around Rien, a handmaid in a feudal society encased aboard a starship hurtling toward a supernova. When Rien starts caring for a mutilated angel, she envisions a better future for both of them.

This puts her into conflict with the A.I. that runs the ship, the ruling houses of her society, and the genetically-engineered crew struggling to save the ship from certain doom.

aurora

Aurora

By Kim Stanley Robinson

Kim Stanley Robinson is best-known for his meticulously detailed hard sci-fi novels. He brought that same melding of minutiae, plausibility, and adventure to the generation ship narrative Aurora. 

The novel begins at the end of a generations-long journey to a distant planet known as Aurora. When the landing and settlement prove more dangerous and deadly than anticipated, a group of would-be colonists led by a young woman named Freya decide to turn the ship around and make the journey back to Earth. However, this decision could be more perilous and difficult than staying on the dangerous new world. 

Aurora is a fascinating dissection of the tropes of generation ship fiction, and the psychological strain interstellar travel could present.
