Solar storm

In Shelter, Cas, Ori, and their parents must deal with the direct hit of a solar storm on Mars while away from the shelter of their base.

Earth is about to get hit by such an event. But don’t worry. Too much…



Humans and lava tubes

Dawn Colony, where the characters of Generation Mars live, is built primarily in lava tubes to protect the inhabitants from the radiation that reaches the surface of Mars.

Recent archaeological research suggests humans have been seeking shelter from radiation in lava tubes for thousands of years.



Let’s talk covers

First, I’ve been so busy finalizing the next book that I missed this announcement in early August. Shelter is a finalist in the Wishing Shelf Book Awards Best Book Cover contest in the Children/Young Adult category. Kudos to Luis Peres for hitting it out of the park with this grand and cinematic vision of a human family facing the challenges of living on Mars.

Aurora borealis

The Sun has been busy lately. Recent coronal mass ejections (CMEs) are hitting the Earth’s atmosphere even as I write this. Because of this atmosphere and the Earth’s strong magnetosphere, the results should be limited to spectacular aurora.

Curious about what happens when CMEs hit Mars, a planet with no magnetosphere and a much thinner atmosphere? Find out in the latest Generation Mars book: Shelter.


Shelter receives Five Star review from Readers’ Favorite

“Douglas D. Meredith created this series as an introduction to hard science fiction for children. Shelter will engage children in wanting to know more about science, planets, and space, and should appeal to a variety of ages. The vocabulary isn’t dumbed down but explained in a manner that makes even the more difficult concepts easy to understand. The attention to detail is precise. Meredith weaves in an undercurrent of longing for earthly things such as wanting to play on the surface, sit and look at the sky, feel the grass, and climb trees. Humor is derived from the way the sisters interact. They may have been born on Mars but they still behave like ordinary kids, such as Ori being excited about working in the crop domes or the two trying to sneak out with a soccer ball to play on the surface. Their relationship is at the heart of the adventure as their love for their family drives them forward and pushes them to be courageous. The illustrations are in black and white which pairs well with the hard science fiction genre and portrays vivid images of the landscape of Mars. This is a great resource for children as it is informative and humorous, with likable characters and an adventure that will spark interest in the genre and a desire to learn about science. Notes are featured after the adventure and include coronal mass ejections, radiation, and gene editing.”

Coronal mass ejection

Sometimes, twisting of magnetic fields within the corona gets so tight that the tension abruptly snaps, sending massive loops of plasma racing away from the Sun in an event called a coronal mass ejection (CME). Most of the time, these clouds of particles dissipate into space without causing any harm.

Sometimes, the cloud of particles is pointed straight at one of the inner planets. When this happens, the high-speed charged particles slam into the planet in what is called a solar particle event (SPE). For planets with thick atmospheres and strong magnetic fields, most of the energy dissipates far above the surface. Mars has neither a thick atmosphere nor a strong magnetic field. When an SPE occurs on Mars, the surface is flooded with high energy particle radiation.

Sometimes, two or more CMEs will happen in the same place on the Sun, one after another. When this happens, the first clears a path for the ones that follow, allowing them to race even faster out into the solar system.

Sometimes, two or more CMEs will happen in the same place on the Sun and point straight at one of the inner planets. When this happens, the SPE on the planet can go on for several days.

One time in particular, when a mother and father and their two children were on their first camping trip, that planet was Mars.

Niger Vallis

“I’m open,” said Nyla. Cas looked up and saw that her mother was standing with knees slightly bent, ready to receive. Cas passed her the ball, and her mother trapped it and dribbled to another spot before passing it back. They continued this—laughing, dribbling, chatting, and passing—until their shadows grew long and the fat blue Sun fell behind the rim of Dao Vallis, far down-canyon from them.
