Why Write About Space Robots (and How Big Is the Solar System)?

I was very excited to discover that SELFIES FROM MARS: THE TRUE STORY OF MARS ROVER OPPORTUNITY earned an orange banner for being a #1 new release in children’s aeronautics & space books!

I have several other works-in-progress about space robots, including a fictional story about the real Mars rover Perseverance (and Mars helicopter Ingenuity) and a nonfiction one about the Voyager space probes. And it got me wondering, What it is about space robots that has sparked my imagination?

Considering the size of the universe, and even of the solar system, human space travel is–to put it mildly–very limited. The farthest we’ve been is the moon, on average 238,855 miles from Earth. That’s about the size of 30 Earths, and can be considered really far away in terms of Earthly travel.

How about Mars? Humans haven’t been there yet, but we’ve sent a bunch of robots there, and we might even get there soon. The answer here varies because of the constant rotation of the planets around the sun, but on average, Mars is 140 million miles away from Earth and it get as close as 35 million miles. A lot farther than the moon!

Looking at the solar system, it doesn’t really make sense to talk about it in millions of miles because it’s so large. So scientists use the Astronomical Unit (AU) to describe distances of that size. One AU is 93 million miles, which is the average distance between the sun and the Earth. Neptune is 30 AU from the sun, or 2.8 billion miles. The Kuiper Belt, where Pluto resides, isn’t even the end of the solar system, and that can be as far as 50 AU from the sun.

Depending on how you define the end of the solar system (and there isn’t necessarily consensus on this in the scientific community), our solar system can be measured from 122 AU (at the heliopause, the place where solar winds meet interstellar winds) all the way to 100,000 AU from the sun (at the Oort Cloud, the farthest reach of the sun’s gravitational influence).

So really, really large. And that’s just the solar system, never mind the mind-bending that is required to think about how big the universe is! Still with me?

That brings us back to, What does the size of the solar system have to do with my interest in space robots? Space robots can travel much, much farther than humans can.

Mars currently has two working rovers on it, Curiosity and Perseverance, and a helicopter named Ingenuity. The space probe Voyager 1 has been traveling through the solar system for more than 45 years. At 159 AU (approximately 14.8 billion miles from the sun), it is deeper out in space than any other human-made object, and has traveled beyond the heliopause. And there are numerous other space robots out exploring the sun, other planets, other moons, etc.

Space robots are our ambassadors to space! We can’t go there yet, so we send out these robots. Some of them even look a little like us, and they’re all robot scientists, communicating their findings back to Earth. We learn from them, but they also represent us.

Voyager 1 even contains a Golden Record with sights and sounds from Earth and mathematical instructions on how to listen to it. I love picturing aliens (or future humans) coming across Voyager 1 and listening to that record. What would they (or what would future humans) think of the humans that sent the record out into space?

Anyway, that definitely sparks my imagination. I think it’s also important to learn about those space robots that are out there representing humans in space: our interstellar ambassadors!

Gaining a Sense of Awe and Perspective from the JWST Images and the Vastness of the Universe

As a writer, most people know me as a purveyor of words and stories, but I occasionally geek out here on scientific topics, like the Fibonacci Sequence, space exploration, and the Big Bang. I’ve been combining my love of writing and science in picture books drafts about the Mars rovers and the Voyager spacecraft. My hope is to bring these stories, both fiction and non-fiction, to readers starting next year!

First Deep Field

When NASA released its first wave of images from the James Webb Space Telescope (JWST) on my birthday last week, it felt like the universe was giving me the best birthday present ever: awe and perspective. The above image is known as the First Deep Field. From our earthly perspective, the amount of space we’re looking at in the image is the size of a grain of sand held up to sky at arm’s length (so a very, very, very, very tiny amount).

Many of the reactions to this image were similar to my own of amazement and excitement, but I did see a few less-than-enthusiastic responses. One in particular was along the lines of not getting why people were so excited about a picture of space looking like, well, space.

Without context (and President Biden’s press conference on this image was not exactly illuminating as to the significance of this image), I totally understand the “so what?” reaction. So what is the significance?

First of all, the First Deep Field shows that tiny patch of space in greater detail than we have ever observed before. There are a few stars from our own galaxy there, those are the bright ones that look like sparkly stars. They’re cool to look at, but from a scientific perspective, fairly ordinary. More interesting is that this single image shows a galaxy cluster that contains thousands of galaxies. Our own Milky Way galaxy contains somewhere between 100-400 billion stars, so this image is showing a whole lot of space stuff with an incredible level of detail!

Even more interesting are the distorted-looking galaxies that have a kind of smudged appearance. Due to a phenomenon called gravitational lensing, light can bend around objects and be magnified. So those smudged galaxies are behind other galaxies and are at a much greater distance than we’d normally be able to see.

The thing about light is that it’s very fast, but the universe is so vast, light can travel for a very long time before reaching us here on Earth. Our sun is about 8 light-minutes away, so the sunlight you see right now (please don’t look directly at the sun and damage your eyes!) is 8 minutes old. From Earth, we can only see the sun as it was 8 minutes ago. Light allows us to see into the past!

One distorted galaxy in the First Deep Field is 13.1 billion light-years away. So we’re seeing it as it was 13.1 billion years ago. The farther into the universe we can see, the farther into the past we can observe. This galaxy is so far away that we’re seeing to within 1 billion years of when the Big Bang occurred. And that will allow us to discover more about how the universe was formed–the history of literally everything we know!

That’s only a fraction of the exciting information that will come from this one image from the JWST. Gazing at an image of this tiny bit of space makes you realize how very vast the universe is, large on a scale that is hard to comprehend. There is so much space stuff out there, and we here on Earth are a “pale blue dot” in a soup of many, much larger dots.

At first that makes me feel small and insignificant. I’m one person of billions on Earth. Earth is one planet among countless others circling countless stars in the countless galaxies of the universe.

But then I think of how amazing it is that we’re here at all. In all of that space, we have our beautiful, bountiful planet Earth. I breathe in the oxygen and drink the water with my body that is made of stardust. And I sit here at my computer with a brain complex enough to contemplate the vastness of space and the history of the universe. So when a person shows skepticism about a picture of space looking like space, here’s what I have to say.

Images like this give people a sense of awe, both in the beauty of space and the vastness of it. It simultaneously makes us feel insignificant and helps us realize how special it is that we are here at all. At least that’s why I’m so excited. I hope you find something that excites you today!

I’ll leave you with a couple more awe-inspiring images from the JWST.

The Magic of a Highlights Foundation Writing Retreat

Quick reminder that there are just a couple of days left to get 10% my entire catalogue of books using code NOVEMBER10. Just go to the Purchase Books page and I’ll ship them directly to you. All books are signed with an option to personalize, and all purchases come with fun book swag!

For those of you who have been followers of my blog for awhile, you may remember the last time I went to the Highlights Foundation or a writing retreat and wrote “Highlights Foundation Unworkshop: A Little Creepy, A Lot Productive.” My writing friend Katlyn Duncan and I enjoyed it so much, we scheduled one for the following fall.

Then COVID happened and we had to put the trip on hold, but we finally made back early this month! And it was amazing!!! Yes, amazing with three exclamation points.

With this retreat scheduled for early November and me just starting a draft of my latest young adult novel, all the stars aligned for me to attempt National Novel Writing Month. NaNoWriMo (for short) occurs in November and a bunch of writers attempt to draft a book (i.e. write 50,000 words) in 30 days. It’s an intense experience, and one I was not in a position to attempt in recent years.

This year, I stayed in Cooper’s Cottage, which was a bright and airy cabin full of Floyd Cooper’s illustrations and with a view of the hiking path. It was not haunted, though one of the other writers I was on the retreat with stayed in my old cabin, and (spoiler alert) that one is still haunted. I actually didn’t write much in my cabin because I was retreating with three other writers this year and we mostly wrote in common spaces or in one of the other cabins (but not the haunted one!).

As I said, it was an amazing trip, and I highly recommend a Highlights retreat for all of you creative types. I wrote a ton of words and set myself up for successfully completing my NaNoWriMo challenge (as of November 28 when I’m writing this, I’m at 47, 250 words for the month and on track to finish on time). There’s much to be said of having everything taken care of for you so you have the brain space to only think of writing.

As a teaser for what I’m working on, I composed this poem in the Highlights word garden. As you can see, it’s kind of an intense story, but I’m really pleased with how it’s coming out. Though there will be a ton of revisions to come.

My retreat mates are all vloggers, so you can check out their videos about the experience below. I kind of hate making videos myself, so I’ll be sticking to this old blog for now.

Why Bother With Space Exploration?

This is the second installment of my posts about space exploration. You can check out the first one “Let’s Stop the Billionaires from Controlling Space Exploration” here.

A question that inevitably comes up when discussing space exploration is why bother at all? People will say that space exploration is expensive, that we should focus on fixing all the bad things here on Earth, and what do we humans really get out of it anyway?

Photo credit: NASA

Let’s start with that first one of how expensive it is. In my last post, I mentioned that NASA’s 2021 budget at $23.3 billion. To a single individual (unless you’re the likes of Jeff Bezos or Elon Musk), that kind of money is an obscene amount, but let’s put in perspective. NASA’s budget is a mere 0.5% of U.S. government spending. Contrast that with the 2021 defense budget of $703.7 billion or the 1964 NASA budget adjusted for inflation of $57.3 billion.

Next, let’s talk about how we should focus on our problems here on Earth rather than exploring space. This one almost doesn’t even require a response because it’s not a this-or-that kind of situation; sending humans to the moon doesn’t keep us from feeding hungry people. But I’ll humor the doubters and give an even more thorough response than that, which also addresses what we here on Earth get out of space exploration.

The work that NASA does can actually help solve our Earthly problems. NASA has a program dedicated to climate change with an entire fleet of instruments and spacecraft orbiting Earth to study climate science. Their scientific data is readily available to anyone on the globe, specifically those in charge of making and changing climate policies around the world.

The agency’s research encompasses solar activity, sea level rise, the temperature of the atmosphere and the oceans, the state of the ozone layer, air pollution, and changes in sea ice and land ice. NASA scientists regularly appear in the mainstream press as climate experts.

NASA’s “Taking a Global Perspective on Earth’s Climate”

Space exploration also pushes the development of cutting edge technology and innovation that leads to applications here on Earth. Ever taken a selfie (the rovers on Mars have…see “Watch (and Hear) How NASA’s Perseverance Rover Took Its First Selfie”)? You can thank space exploration for that. Here’s a video about some more of the technologies that have come out of it, including weather forecasting tools, fire resistant fabrics, and medical applications.

Beyond the tangible benefits of space exploration, allow me to wax poetic for a moment about the intangible. Recent studies have shown that experiencing a sense of awe reduces stress, loneliness, and depression and can even alleviate pain (see “Awe: The Instantaneous Way to Feel Good and Relieve Stress”).

What is more awe-inducing than looking up at the stars and imagining what is up there, thinking about the universe and our place in it? Well, actually knowing what is up there! Because as vast as our imaginations are, the more we explore space, the more we realize that some of it is stranger than we can imagine, like a space cloud that smells like rum or a planet composed of solid diamond.

Space exploration gives us mere mortals a chance to see how far we can go as a species, both in actually going into space and by pushing the boundaries of what our minds can understand. It also puts us in our place. One of my favorite ways to get a sense of awe is watch videos about the scope of the universe.

It reminds me that we are a tiny part of a vast world, barely even a blip in the 14-billion-year history of the universe. Yet (barring any secret alien files the government has) Earth is the only planet we know of that has life on it. And it has a vast array of life, an estimated 8.7 million species, all on this one speck of a planet.

We are insignificant in the scope of the universe, but we are also diverse and important in the complex web of it, probably in ways that we can’t imagine. Understanding our greater place is all part of exploring it. So, yeah, space exploration is important and worth doing.

I’ll leave you with one last quote from NASA before I circle back to those billionaires who want to take control of space exploration on my next post.

Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations. Curiosity and exploration are vital to the human spirit and accepting the challenge of going deeper into space will invite the citizens of the world today and the generations of tomorrow to join NASA on this exciting journey.

Writing Nature Fantasy with Sara Webley Author of ZO IN THE ROOSTING TREE

Crows are an important part of my witchy middle grade book, so it felt very serendipitous when I connected with Sara Webley, author of ZO IN THE ROOSTING TREE. Let’s give a big welcome to Sara and and her clever crow character Zo!

Besides writing books for young readers, I’m an editor of texts ranging from academic writing to consumer health to kids’ books. I’ve also worked in the zoo and aquarium field as an animal technician and zookeeper. I love fiction and nonfiction about animals and nature. So when I decided to write a fantasy about a young girl who switches places with an American Crow, I wanted to combine the real with the magical—nature with fantasy. Write what you know, but…twist it! I wanted my readers to view nature from the perspective of the animal.

So I had to decide: How to construct Zo in the Roosting Tree? How to bridge reality and fantasy?

I began by researching crow behavior, crow myths, crow intelligence. Write what you know—and anything you don’t know, educate yourself about it! So I was continually checking: How would a real crow act in the scene I’m writing? What cool example of crow behavior can I include? This research gave me a framework for creating my plot and characters. What I aimed for was a fantasy close enough to reality that it would pull my readers in and make them wonder…Could that really happen? Would the crow I see outside my window every day be able to do that? And…Is that crow watching me?

The crow and human needed to switch places, so they could each learn about the other’s world. Because of my own bond with nature, I created a human character who loves birds: a young girl named Jae, who would live inside Zo the crow’s body. And the crow would live inside Jae’s human body. That’s the magical “Switch”—girl and crow, crow and girl. I hoped to excite young readers about a bird they probably see every day and don’t think much about. I wanted them to care about animals by being one for a while.

I made choices about plot, scenes, conflicts, and fun based on what I know about real crows. Planning my storyline, I wanted the magical crow Zo to behave in ways that reflect reality. Crows are smart, social, playful, adaptable birds. So I made Zo clever, fun-loving, family-oriented. Crows recognize human faces—people they like, and people they don’t. Crows are also problem-solvers, comparable in intelligence to monkeys and dolphins. They can use tools to find hidden food, slide down a snowy windshield just for fun, or surf the clouds by gripping a big piece of bark with their toes. So I set some problems in front of Zo to see how she might solve them—like being hunted by a scary owl at dawn. Zo may live in a fantasy world, but her behavior reflects the skills of a real crow.

But what’s fun about writing nature fantasy is not having to be totally accurate! After editing academic writing for years, I needed a 180-degree turn. So I took liberties: A real crow would not be friends with a young cardinal. A real crow would not ride on a snapping turtle’s back. I enjoyed starting with what I knew about the true nature of crows, and then twisting that into fantasy.

My goal was also to get readers interested in the much-maligned crow (think: Hitchcock’s The Birds) by presenting a sympathetic crow who teaches us something about natural behavior. This winter, a friend told me that she’d seen a huge group of crows gathering in a parking lot before they flew off to roost for the night. She said it made her think of “the apocalypse.” That’s what I wanted to counter with Zo’s character, by showing readers how crows communicate, play, and care for each other. In that parking lot, those crows were probably discussing where to find food the next day, not planning the apocalypse!

Nicer beliefs exist about crows, too: they’re famous for leaving “gifts” for humans. There’s some disagreement about that among bird scientists, but I wanted to use a shiny gift in the plot. I make silver chain maille bracelets, so I decided that Jae would have one. The real bracelet jump-starts the magical crow-and-girl Switch. Nature and reality…with a fantasy twist.

ZO IN THE ROOSTING TREE blurb:

Caw! Zo looks like a crow, sounds like a crow, and flies like a crow. But Zo thinks she’s a human girl inside!

Zo in the Roosting Tree tells the story of a clever crow, through the eyes of a human girl. A girl who loves being a crow, but who must find the secret to being human. Follow Zo’s adventures as she wakes up one morning in the roosting tree, learns to fly, plays games with a goofy cardinal named Rufus, and surfs the wind with her wings in the clouds. Kahr! Kahr!

Being Zo the crow is fun. And Rufus has become her best birdy friend. But when Zo discovers the dangers of her new life—owls and bobcats and cars—she misses her human family. Time is running out. Can a mysterious snapping turtle help Zo find the magic she needs to go home again?
