Fill in the details and get an invitation text to print or send. To go with it: the moon phase on the party day and how many trips around the sun the birthday child has made.
The countdown is on!
What did the moon look like on the day of birth?
Ideas for the invitation card
Glue it onto a toilet-paper-roll rocket and tuck the invitation inside as a scroll.
Put a few glow-in-the-dark stars in the envelope – they shine when guests open the card in the dark.
The highlight of every space party: everyone counts down out loud, and then the rocket lifts off – maybe straight to the birthday cake?
The mission plan: a party schedule
An example for three hours. Leave some breathing room – little astronauts need a break now and then too.
Check-in at the spaceport: Every guest gets an astronaut ID with their name and makes a helmet or alien antennas.
Rocket launch: Everyone counts down from 10 together – and then there's cake as rocket fuel.
Astronaut training: Three or four game stations in turn: balloon rocket race, meteorite hunt, moon walk and black hole.
Space quiz: The rocket teams compete in the quiz. Every right answer earns a star.
Food on board: Planet pizza, rocket fruit skewers and astronaut drinks refuel the crew.
Certificates and landing: Every child gets an astronaut certificate and a party favor, then everyone lands safely with their parents.
Decorations: turn the living room into a space station
Night-sky table: A dark blue or black tablecloth, star confetti and a few glow-in-the-dark stars.
Hanging planets: Colorful balloons in different sizes as planets. For Saturn, simply tape a cardboard ring around the balloon.
A Milky Way of lights: A string of fairy lights zigzagging across the ceiling or wall, with cotton wool as star clouds.
Moonscape: Gray pillows and blankets, crumpled aluminum foil and a few moon rocks on the floor – perfect for photos with an astronaut helmet.
Airlock: Strips of aluminum foil or silver ribbon hanging in the doorway: every guest enters the space station through this airlock.
Cardboard-tube rockets: Paint toilet paper rolls and add a paper nose cone – as table decorations or as name cards.
Games for little astronauts
All games work indoors and outdoors and need hardly any materials.
Balloon rocket race: Stretch a string across the room and thread a drinking straw onto it. Tape a blown-up balloon to the straw and let go: the balloon zooms along the string, pushed by thrust like a real rocket. Which team gets the farthest?
Meteorite hunt: Beforehand, wrap stones in aluminum foil or paint them silver and hide them in the yard or around the house. Who finds the most meteorites? A few rare golden ones count double.
Slow-motion moon walk: On the moon everything is lighter and slower. The kids hop along a course like astronauts in slow motion while balancing a moon rock – a ping-pong ball – on a spoon.
Black hole: One child is the black hole and tries to catch the others. Whoever gets caught holds hands and becomes part of it – until nobody can escape, not even light.
Astronaut training: An obstacle course like real astronaut training: crawl under the table through the airlock, balance along a line across the space station, then undo buttons or build with blocks wearing thick gloves – that's how hard it is to work in a spacesuit.
Alien freeze dance: Put on space music and everyone dances like aliens. When the music stops, everyone freezes weightlessly in place. Whoever wobbles has to make an alien noise.
Planet relay: Eight planet cards lie jumbled at the end of the course. The teams fetch them one by one and lay them out in the right order. Memory trick: My Very Educated Mother Just Served Us Noodles – Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Constellation flashlight: A grown-up uses a nail to poke the pattern of a constellation, like the Big Dipper, into the bottom of a paper cup. Put a flashlight inside, switch off the lights – and the constellation shines on the ceiling. Who guesses it first?
Food from the moon
Planet pizza: Top mini pizzas as planets: a pepperoni Mars, a cheese moon with corn craters or a striped bell-pepper Jupiter.
Moon phase cookies: Twist apart sandwich cookies with white cream and scrape away the cream to make a crescent, half moon and full moon. Who can put all eight phases in the right order?
Rocket fruit skewers: Thread melon chunks, grapes and banana slices onto skewers and top them with a strawberry as the rocket's nose.
Galaxy cake: Chocolate cake with a dark blue or purple glaze, sugar stars and edible glitter.
Asteroid snacks: Popcorn, chocolate balls or cheese puffs in a bowl as the asteroid belt.
Astronaut drinks: Juice boxes or pouches – that's how real astronauts drink too, so nothing floats away.
Crafts: the gear for the mission
Astronaut helmet: Turn a large cardboard box upside down, cut out a window for the face and paint it silver or cover it in foil.
Rocket backpack: Cover two empty plastic bottles with aluminum foil, add flames of red and yellow crepe paper at the bottom and ribbons as straps – and your jetpack is ready.
Alien antennas: Twist pipe cleaners with colorful pom-poms onto a headband.
Moon phase wheel: Put two paper plates on top of each other with a window cut into the top one: as you turn it, the moon moves through its phases.
Party favors for the trip home
A little bag of stardust, like fizzy candy or sugar sprinkles
When it gets dark: real stargazing
In fall and winter it gets dark early – perfect for heading outside after the party to find the moon, bright planets and the first constellations. The night sky page for your city shows which ones you can see tonight.
A special extra for the birthday card: what did the moon look like on the day the birthday child was born? And which star has been sending its light to us for as long as the child has been alive?
Questions about an astronaut birthday
What age is an astronaut party best for? It's ideal for children aged 4 to 10. Little ones love the alien freeze dance and the meteorite hunt, older kids the space quiz, the balloon rocket race and the constellation projector.
How many children should I invite? A popular rule of thumb: as many guests as the age the child is turning. Four to ten children are ideal for the team games.
How much does a space party cost? Very little: most things – helmets, rockets, meteorites and the decorations – are made from cardboard, aluminum foil and balloons. The invitation, quiz and certificate are free to print here.
What if the weather is bad? All the games work indoors too. With fairy lights, glow-in-the-dark stars and the constellation projector, a darkened room even makes the best space station.
How long should the party last? Two and a half to three hours is ideal for elementary school kids. The mission plan above shows a schedule that isn't too packed.
