Why am I passionate about this?

As a long-term advocate of space colonization I’ve always been drawn to Mars, not by adventure stories but by the idea that ordinary people may someday live there. So this was the theme of my first novel. I wrote it before we had gone to the moon, though it wasn't published until 1970, after my better-known book Enchantress from the Stars. When in 2006 I revised it for republication, little about Mars needed changing; mainly I removed outdated sexist assumptions and wording. Yet the book still hasn’t reached its intended audience because though meant for girls who aren’t already space enthusiasts, its publishers persisted in labeling it science fiction rather than Young Adult romance.

Book cover of The Case for Mars: The Plan to Settle the Red Planet and Why We Must

Sylvia Engdahl Why did I love this book?

Robert Zubrin is the foremost authority on how to get to Mars, and in addition to his engineering expertise, he is one of the most prominent advocates of colonizing it. This classic book, now in its updated 25th Anniversary edition, should be read by everyone interested in the future of humankind. It contains more technical detail about space travel than some people will care to learn, but that can be skimmed; the section about colonization, and the concluding chapter explaining why going to Mars is important, are what I chose it for. In Zubrin's opinion and my own, Mars is "the door to an open future, a new frontier on a new world, a planet that can be settled, the beginning of humanity's career as a spacefaring species."

By Robert Zubrin, Richard Wagner,

The Case for Marsmakes living in space seem more possible than ever in this updated 25th anniversary edition, featuring the latest information on the planet's exploration and the drive to send humans there.

Since the beginning of human history, Mars has been an alluring dream—the stuff of legends, gods, and mystery. The planet most like ours, it had long been thought impossible to reach, let alone explore and inhabit. But that is changing fast.

In February 2021, the American rover Perseverance will touch down on Mars. Equipped with a powerful suite of scientific instruments—including some that will attempt to make…


Book cover of Mission to Mars: My Vision for Space Exploration

Sylvia Engdahl Why did I love this book?

Buzz Aldrin, best known for having been one of the first two astronauts to walk on the moon, has been active throughout the time since then in promoting an expanded space program. In this book he goes into detail—but not too much detail for non-technical readers—about how space activity can help to preserve Earth, in addition to describing various proposals for returning to the moon and reaching Mars, He believes explorers should go there to stay permanently and build a base rather than return to Earth between trips. The book, published in 2013, was overoptimistic in suggesting that as early as 2020 selected astronauts could be asked to commit to spending the rest of their lives on Mars, but I’m sure that when opportunity arises there will be volunteers.

What is this book about?

Can astronauts reach Mars by 2035? Absolutely, says Buzz Aldrin, one of the first men to walk on the moon. Celebrated astronaut, brilliant engineer, bestselling author, Aldrin believes it is not only possibly but vital to America's future to keep pushing the space frontier outward for the sake of exploration, science, development, commerce, and security. What we need, he argues, is a commitment by the U.S. President as rousing as JFK's promise to reach the moon by the end of the 1960s-an audacious, inspiring goal-and a unified vision for space exploration. In Mission to Mars, Aldrin plots that trajectory, stressing…


Book cover of How We'll Live on Mars

Sylvia Engdahl Why did I love this book?

This is a short but comprehensive overview of why we need to colonize Mars and the problems that must be solved in settling it. We would already be there, Petranek points out, if we had preserved and improved the technology that got us to the moon. In his view, NASA has accomplished little of value during the hiatus. But now private companies are making real progress toward turning humankind into a spacefaring species, which is essential both as insurance against disaster on Earth and because “when the first humans set foot on Mars, the moment will be more significant in terms of technology, philosophy, history, and exploration than any that have come before it.” I recommend this book not so much for the information it contains as for the inspiration it offers.

Part of the TED series: How We'll Live on Mars

It sounds like science fiction, but award-winning journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity, and explains in fascinating detail just how it will happen.

It's clear that the race is on. Private companies (driven by iconoclastic entrepreneurs like Elon Musk and Sir Richard Branson); Dutch reality show/space mission Mars One; NASA and the…


Book cover of In the Shadow of Deimos: A Terraforming Mars Novel

Sylvia Engdahl Why did I love this book?

Most realistic fiction set on Mars is about small exploratory expeditions. There is surprisingly little available about colonization that doesn't bring in the discovery of intelligent inhabitants or a lost civilization, or at least traces of one having existed in the past. And the few novels with no fantastic elements tend to focus on political controversy. So I was happy to find this recent book that depicts what a colony on Mars might really be like. It's based on the board game "Terraforming Mars," which I haven’t seen, but doesn't depend on any knowledge of the game. The story is part murder mystery and while it’s intended to be entertainment rather than serious literature, it will be enjoyed by readers who are excited by the idea of settling a new world.

Book cover of First Landing

Sylvia Engdahl Why did I love this book?

I'm not supposed to list two books by the same author, but they are very different since one is nonfiction and the other fiction, and given the dearth of realistic stories about colonizing Mars I think this one should be included. As Zubrin is an expert on the scientific and technological aspects of travel to Mars, they are described as accurately as our present knowledge permits, though of course the situation on Earth and the details of the envisioned expedition are wholly fictional. What sets it apart from similar novels is its presentation of the idea that merely exploring Mars is not enough—for the sake of humanity's future families must live there, and some people, despite differing and seemingly - irrational grounds for their conviction, will instinctively know this.

This book (and its sequels) are about overcoming the odds; about learning to improve the skills and abilities you have, rather than dwelling on what you can't do. Conflict, plague, and scheming politicians are all featured along the way–but none of the characters are human!

Unreachable Skies

What is this book about?

When a plague kills half the Drax population, and leaves the hatchlings of the survivors with a terrible deformity – no wings – suspicion and prejudice follow. Continuously harassed by raids from their traditional enemies, the Koth, the Drax are looking for someone, or something, to blame.

Zarda, an apprentice Fate-seer, is new to her role and unsure of her own abilities; but the death of her teacher sees her summoned by the Drax Prime, Kalis, when his heir, Dru, emerges from his shell without wings.

A vision that Dru will one day defeat the Koth is enough to keep…
