Last month a retired bus driver cornered me at a family dinner and asked, with total sincerity, why astronauts float if gravity is “still there” up in space. Nobody had ever answered that for him in a way that stuck. I realised I had been explaining space to an imaginary crowd for years, and a crowd never asks you to slow down. He did. This list is what I wish I had known before that conversation: eight habits for explaining space to one curious beginner, with the crowd politely shown the door.
1. Start with the person’s actual question, not your favourite fact
The bus driver did not want a lecture on the history of spaceflight. He wanted to know why the pictures looked the way they did. When you hold one specific question in your head, half of your material becomes optional on the spot. Ask yourself what this person typed into a search box at eleven at night, and answer that sentence first. Everything else is garnish.
2. Pick a comparison from their own life
A pilot would be happy with a talk about energy and velocity. A bus driver has felt a vehicle drop over a crest in the road and left his stomach behind. So I told him that the station and everyone in it are falling all the time, just moving sideways so fast that the ground keeps curving away beneath them. That image comes from his working day, not from my textbook. A good space comparison is borrowed from the learner, never from the explainer.
3. Decide how much time they really have
Some beginners have a coffee break; some have a whole weekend. Writing for a person who has four minutes produces a different piece than writing for someone who wants to sink in. Say the time budget out loud in your notes: “this reader will give me one screen and a half.” Then cut until the piece fits. Short is not unkind when it respects the clock of the person on the other end, and it is often the kindest thing available.
4. Name their worry before you solve it
Beginners rarely say it, but many of them worry about sounding silly. The bus driver prefaced his question with “this is probably stupid.” It was not stupid; it is one of the most common questions people have about orbit. A single warm sentence such as “plenty of people stumble on this exact point” lowers the temperature of the whole explanation. Nobody learns well while bracing for embarrassment.
5. Give one idea per sitting, then stop
Orbits, escape velocity, weightlessness, re-entry heating and launch windows can all be attached to the same topic, and a crowd-friendly article will try to touch every one of them. A single reader cannot hold all of that at once. Choose the one idea that unlocks the question, build it carefully, and leave the rest for another day. If you want to extend the lesson, point to a gentler follow-up, such as our simple tour of the high orbit that satellites use for steady coverage, so the learner can come back when they are ready rather than being pushed forward.
6. Let them draw it, even badly
I handed over a napkin. The bus driver drew a hill, then a ball rolling off it, then a longer hill and a faster ball, until the ball simply never landed. His drawing was ugly and entirely his own, and he remembered it long after he forgot my wording. When you write instead of speak, you can imitate this by asking the reader to try something small: toss a pen from one hand to the other and notice the arc, then imagine tossing it harder. A tiny task turns a spectator into a participant.
7. Keep the jargon on a leash
Every field has words that feel invisible to insiders. In space writing the usual offenders are the names of orbits, the phases of a mission, and the alphabet soup of agencies. Choose one term that the person genuinely needs, define it in plain words the moment it appears, and park the rest. If they want a calm walk through the lower orbit most crewed missions use, our beginner-level orientation to the region just above the atmosphere introduces the vocabulary slowly, one piece at a time. You do not need to pour all of it into a single piece.
8. End with a door, not a wall
After the napkin, the bus driver asked a second question, and then a third. A good ending hands the reader a next step small enough to take tonight: a thing to look up, a sky event to watch for, or a plain sentence they can repeat to a friend. This is the real test of the explanation. If they can retell it in their own words, you reached them. If they can only nod, you probably reached nobody. In that case, go back to the person you pictured and rewrite it for them again.
Where to put your explanations once you have written them
Writers who work this way often want a quiet place to publish the result without building a website first. A blogging platform such as iBlogUp, where writers publish their stories on a personal subdomain, is one option; readers can follow along there, including through an RSS feed, so your one curious reader can return for the next explanation without hunting for it. It describes itself as free, which is worth checking for yourself before you commit.
A short worked example from the same dinner table
To see these habits working together, imagine rewriting the answer I gave him as a small piece of writing. The question becomes the headline, so he knows within a heartbeat that the page is for him. The first paragraph confirms that the question is a good one. The second offers the road-crest comparison. The third asks him to draw the hill and the ball, and the fourth names the single new word he needs, which is the word for falling around a planet instead of onto it. A fifth paragraph says what to look for next time a station crosses the evening sky, and when to step outside. Five short paragraphs, one reader, no crowd.
Notice what is missing. There is no list of every altitude band, no timeline of space agencies, no apology for the parts left out. The omissions are not laziness; they are the result of a decision that the reader’s attention is a gift and that gifts should not be wrapped in clutter. If a different reader wants the omitted material, that is a different piece for a different person, and it deserves its own careful afternoon.
There is a second benefit that surprised me. When I wrote for him, I found my own understanding was shakier than I had believed. The napkin exposed a hole: I had been repeating the phrase “microgravity” for years without being able to explain it from scratch. Having one real face in mind exposes that kind of fog quickly, because a real person will say “but why?” and a crowd never will. Writing for one is also a way of being more honest about what you actually know.
Common slips when you try this the first time
The most frequent mistake is to choose an audience of one and then quietly widen it halfway through, adding a paragraph “for the experts” or a side note “in case anyone is wondering”. Resist that. The expert paragraph is a signal that you stopped trusting your reader. The second mistake is to pick a person who is secretly yourself, a version of you from five years ago who somehow already knew everything. Choose someone who really does not know yet, and make them specific: a neighbour, a nephew, a colleague from accounts who watches launches on a phone during lunch. The third mistake is polishing the opening forever. Write the plain answer first; decorate it only if the reader would miss the decoration.
Finally, remember that kindness and clarity are not extras. They are the point. For one person at a table, a clear explanation delivered gently can change how they look at the night sky for the rest of their life. For a crowd, the same explanation bounces off. So next time you plan a space post, name your reader before you open the document, hold their face in mind, and write to them. The topic will wait for you, and so will the rest of the universe, but a curious person with a napkin might not wait long.
