Space word search
Twelve space words are orbiting this grid, from a quick moon to a full nine letter astronaut. No telescope required, though there is one hidden inside.

Drag across the letters to select a word. Words hide across, down and diagonally, forwards and backwards. Works with mouse and touch.
Mission manifest
Planet, rocket, galaxy, astronaut, comet, Saturn, meteor, orbit, stars, moon, telescope and alien. MOON is the trap of the board: four letters, two of them the same O, in a grid that is naturally full of them. ASTRONAUT and TELESCOPE are the long anchors; their rare letter pairs (the T-R and the T-E-L openings) give them away fast.
For small astronomers
Space is the theme that turns a word search into twenty follow-up questions, so be ready for what a comet actually is (dusty ice, in short) and whether aliens are real (the grid remains neutral). One nice ritual: each found word earns one space fact from an adult, which converts the puzzle into a stalling device of roughly half an hour.

Frequently asked questions
Is the space word search free to print for my classroom?
Yes. The space word search is free to print for classrooms, science clubs, planetarium visits and home, in any quantity and with no attribution required. Teachers use it as a topic starter. The PDF may not be sold or uploaded to another site, as the licensing policy explains in plain language.
What age or reading level is the space puzzle?
Ages 7 to 11, or US grades 2 to 5, slightly older than our animal puzzles because of the vocabulary. The 12x12 grid holds twelve space words up to nine letters (ASTRONAUT, TELESCOPE). Words like GALAXY and ORBIT are worth a one line explanation while you solve it together.
Can we play the space word search online?
Yes. The grid on this page plays in the browser on any device, including a classroom whiteboard, and each word you find is struck off the list. Nothing to install and no account. If you want a paper copy for a science folder, the free printable PDF is beside the puzzle.
Is there an answer key?
Yes. A separate solution PDF marks all twelve space words on the same 12x12 grid. Download it with the Solution button. It exists as a separate file precisely so a teacher can print thirty clean puzzle sheets and keep the answers on the desk.
Seven space word searches to print, one for each distance from here
Six extra boards, ordered outwards: the solar system, the hardware, the people, one specific week in July 1969, the constellations and the part of the universe nothing has ever reached. The winter sky is a separate board on the winter word search, which already owns the aurora, the Pleiades and the Big Dipper, so the constellation sheet here had to find twelve more and did. Two word terms run together on the grid: asteroid belt is ASTEROIDBELT, one small step is ONESMALLSTEP, light year is LIGHTYEAR.
The 12x12 board on this page
The board above, printed as it stands: twelve words from the first space book a child owns, with ASTRONAUT and TELESCOPE as the nine letter anchors and MOON hiding in a grid full of O.
The planets: the whole solar system on one sheet
A 13x13 board with the tour in order: Mercury, Venus, Earth, Mars, Jupiter, Uranus, Neptune and Pluto, plus the asteroid belt between four and five, the gas giants, a crater and an atmosphere.
The hardware: what actually goes up
Twelve pieces of real machinery on a 13x13 board: Apollo, Voyager, Hubble, the space shuttle, Soyuz, the probe, the lander, the rover, the space station, the launch pad, the booster and the capsule that comes back.
The people, 14x14: who has actually been
A 14x14 board for the job itself: Gagarin first of all, then Tereshkova, Glenn, Armstrong, Aldrin, Collins and Sally Ride, plus the spacesuit, the spacewalk, weightlessness, the training and mission control on the ground.
July 1969: one week, one board
The narrowest axis on the page and the best one, a 14x14 board of eight days: the Saturn V, the lift off, the lunar module, Tranquility, the footprint in the moon dust, the one small step, the lunar rover and the splashdown.
The constellations: twelve the winter board does not have
A 13x13 board of patterns rather than objects: Cassiopeia, Andromeda, Perseus, Cygnus, Lyra, Draco, Scorpius, Taurus, Gemini, Canis Major, Ursa Minor and the Southern Cross that no northern reader ever sees.
Deep space: the hardest sheet on the page
A 14x14 board for the part of the universe nothing has visited: the black hole and its event horizon, the supernova, the quasar, the pulsar, the wormhole, dark matter, the red shift, the light year, the big bang and antimatter.
