OK, so my birthday is coming up and I decided that it needs to be space themed. I mean, Star Wars would be cool too, but I want to save that level of high effort for when I can actually invite people over. Even if it’s just us, though, how do you throw a space themed birthday party for adults?
I think too often we let ourselves “grow up” too much. Why should fun birthday parties stop after childhood? Why can’t I make space themed drinks and share them with my space loving grown up friends?
The cool thing about this theme is it’s fun for girls, guys, and theys. Really, anyone who loves space. I find that a lot of themed birthday adult parties can get really feminine, but space is a bit more neutral.
I mean, who doesn’t love space?
You can use your own tastes to put a unique flair on the grown-up space themed birthday ideas. They’re not too mature, though – the whole point is to have fun!
I also find this great post about Space Themed cocktails for you to try!
Decoration Ideas for an Adult Space Themed Party
These are some of the coolest and thematic space themed decorations I could find that would be perfect for adults too.
Need somewhere to host a party? Here’s some great ideas for party spaces.
Solar System Disposable Dishes
You’re an adult and that means you don’t have anyone to clean up after you. Save on time after the party putting out some disposable dishes… Space themed, of course.

Space Themed Table Cloth
This one is pretty simple and will match pretty much any sub space themes you decide to go with. It’s sophisticated and mature, just like you space party animal.

Galaxy Style Balloons
These round balloons are just what your space themed birthday party is missing. You can fill them with air or helium depending on the look you’re going for.

Star Garland
You can use this simple garland in a lot of different ways. Drape them over the table, hang them from doorways, or decorate a wall. There’s a couple different colour options, too, so you can buy ones that fit your theme.

Space Backdrop
How else are they going to Instagram your totally Instagrammable event? This backdrop doesn’t come with the stand, so keep that in mind when ordering. You can hang it up in your party space for a trendy photo op or put it behind your focal point (usually the table with the food) for an extra decorative touch.
Available in multiple sizes

Happy Birthday Banner
You’re never too old for a birthday banner! They have ones that are more “space” but I found them childish. If you like those better, though, go for it!
Letters are 6.6″ long

NASA Recruitment Poster
This would also make a great gift for someone who loves space, but I love this as an adult themed space birthday decoration idea too.

Silver Metallic Tinsel
Hanging this metallic tinsel up as a backdrop really makes a space pop. Not only does it reflect light and draw attention, the texture ads dimension to otherwise flat party decor. Just make sure you grab a few panels – they don’t cover a lot of horizontal space.
Covers 3 x 9.3 feet

More Space Themed Tablewear
Depending on your style this set might work better for a space birthday party. I like that it has big and small plates, cups, and napkins. Plus the design is pretty neutral too.

Glowing Stars
You might have had these on your bedroom ceiling as a kid but we’re bringing them back! Once it starts getting dark outside these fun stick on stars will give your space-themed birthday party the glow it deserves.

Metallic Balloons
I love using metallic balloons to decorate all kinds of party themes, but they’re especially thematic when you’re pretending to be in outer space. This set comes with a nice variety of colours and the balloons are suitable for air or helium.

Star Banner
Hang banners all around the room for an easy way to bring the theme together. I like this one because the stars are shiny, simple, and will match whatever space (get it?) you put them in. Plus they’re not too childish!

Galaxy Party Kit
If your adult space party is more of a galaxy party then you’re going to love this disposable dish set. It comes with the tablecloth, plates, cups, and napkins so you don’t have to run around finding things that match.

Inflatable Alien
These are so 90s I just had to include them. Delight your guests by including balloon aliens in your space party decorating… Here’s best part – you get 12 in the pack!

You can’t send you guests home empty handed! Even adult birthday parties can have fun favour bags to give out to your guests as they leave. Here’s some fun stuff you could include.
Space Treat Bags
I like how dark these treat bags are. They just simple paper bag style and you’ll probably want to do something to secure the bag closed. My pick would be folding it over and securing with a space-themed sticker.
Pack of 24

Galaxy Favor Bag With Handles
If you prefer bags with handles, these cute galaxy style ones might be better. They’re actually reusable, too, so the bag itself is part of the gift.

Be a Kid Again
Sometimes it’s fun to just go full on childish with adult birthday party favors. You could use these as bag fillers to compliment a nicer item, or just on their own.

NASA Silicone Bracelets
These are actually super cute. I know I’d personally wear one! Another idea is to hand these out at the start of the party so everyone can have a space themed accessory to enjoy throughout the evening.

Stickers
Stickers are fun at any age but recent trends have opened up a whole new world of cool stickers for grown ups to enjoy. Grab a pack of your favourites, or use this one that has an assortment.

Patches
Like stickers, patches are super trendy right now. Let your guests leave with some of these open ended accessories that they can add to their bag, hat, coat, or whatever! Just make sure they’re cool like this Apollo 11 mission patch.

If you’re going to include snacks then it just has to be this one. Who doesn’t like freeze dried ice cream anyway?

OK so you’ve been invited to a space themed party… But what do you put on? Well, the actual answer is going to be up to your host, but here’s some fun ideas I found that you might want to use.
NASA T-Shirt (or NASA Anything)
It’s a faithful classic that won’t steer your wrong. Wear NASA logo stuff (there’s plenty out there) to a casual space themed birthday for adults and while you won’t steal the show, you’ll definitely fit in.
Comes in small to 3xl

Novelty Space Socks
Even if you don’t want to theme you whole outfit you can still get a little bit of space fun in with novelty socks. These would be great if you were attending a more formal, dress up adult space themed party.

The Moon
It definitely will make you stand out. The moon may orbit the Earth, but if you wear this to a space themed party people will probably be orbiting around you. Probably to ask why you’re dressed as the moon.

Funny T-Shirt
Show off your personality with a funny space themed t-shirt. This one has cats being abducted by aliens, which is amazing, but you can find one that more suits your personal tastes too.

Sexy Astronaut Costume
Insert something about Halloween being the one day of year where girls can dress up like… You know. Don’t limit this costume to just women, though, anyone can get in on this sexy space themed fun!

Do you know where there’s no air? Space. Better come prepared with your very own astronaut helmet to keep you safe. This one is made of soft materials so you’ll be comfortable all night long.
Might be too small if you have a big head

Alien Headband
I think these are adorable. You could even get them to hand out to guests as they arrive so everyone has as “costume” that fits with the theme. Oh, did I mention they glow in the dark too?
