Building the best Lego space sets is great fun, which is why they're so popular. Lego and space have had a strong connection for decades, fitting together to create some of the very best sets in the Lego-scape. From the classic blue and translucent green sets of the '80s to the incredible NASA-accurate builds that have come more recently. The more modern the set, the more scientifically accurate they've become, which leads to some fascinating discovery as well as great entertainment.
We've featured a mix of Lego Space playsets, which are excellent for children aged five and up, and the scale models of real spacecraft, perfect for adults and older children. The sets offer a window into how we view space, both imaginatively and in scientific reality. This guide is split into those two categories - the more adult sets and the ones for younger builders.
If you want to expand your own Lego universe, don't forget to check our Lego sets for adults, and our best Lego Architecture and Lego City sets. And for more hours of fun at home see our guide to the best jigsaw puzzles.
Best Lego space sets for adults
Why you can trust Creative Bloq
If you're into nostalgia pieces, you won't do better than this. The Lego Icons Galaxy Explorer is a magnificent example of a modern piece based on a design classic. Heavily inspired by the 1979 version, but much bigger (21.26-inches long!), it's a 90th anniversary celebration kit with a premium feel that's just for adults (and careful kids!).
It's packed with features including three retractable landing legs, opening rear doors and an extendable ramp. You are able to open the cockpit, where you'll find seats for the four astronauts that accompany the space vehicle – and there is even a living area complete with beds. We are starry-eyed over this amazing set.
Released in honour of the 50th anniversary of the lunar landing, the Lego Apollo 11 Eagle Lunar Lander is a glorious display piece. Lego worked with NASA on getting the details right, including the right shade of gold. There are loads of fun details in the Lego Creator Expert NASA Apollo 11 Lunar Lander, from the way you build the lunar surface (including little square footprints for your astronauts), to the fact that the lunar escape module disconnects from the landing gear to rocket away. There’s even an inside to the module with equipment panels.
This has been a long time coming. International Space Station models would regularly make their way through Lego Ideas, where people submit propositions for new sets to be voted on by the public, and the most voted will be assessed by Lego for potential release as a set. Lego never picked them up… until now! This Lego Ideas International Space Station comes with lots of nice touches, including a robotic arm for deploying a satellite, a scale space shuttle you can dock, a mini cargo spacecraft, and a microscale figure to head out on space walks. If you’re into space, science, and singular achievements, this is pretty much an essential display piece, especially since it comes on a handy stand.
Here’s the thing: this the this NASA set is no longer made by Lego. It has been retired – possibly forever, possibly not, but definitely don’t expect it back soon. Normally, we wouldn’t recommend things that aren’t actually available anymore, but this is easily the best space set Lego has ever made, and you can find it for sale online since it's only a recent retirement, so we kind of have to mention it.
A full metre long when complete, this scale model of the Saturn V is utterly awesome, and meticulously detailed – from its recreation of every portion of the multi-stage rocket, to the little dioramas of the lunar module on the moon and the command module in the sea after a touchdown… and all with microscale figures, as a reminder that this is all to scale!
Moon landing buffs should take note of the number of pieces it’s made from, even – that’s the care and love that was clearly poured into this set. So, if you see it for sale for a not ridiculous price, we can’t recommend it enough. If you're a big space program fan, it's worth it.
Best Lego space sets for kids
This brilliant three-in-one Space Rover Explorer set comes complete with astronaut and alien minifigures. Because every space traveller needs a little green sidekick, right? A brilliant set for kids aged eight and over, this hardy space vehicle includes a working crane arm and a cool mini robot with working arms too. The Space Rover itself includes an incredible amount of detail inside, including a bed, desk with computer, and robot arm to provide the astronaut with his morning coffee. This is a retired set, but it still can be found to purchase so we're leaving it here – it's that good.
The City range might seem a slightly odd place for all the following sets in this list to sit, but that’s where this kind of playset tends to go, so fair enough. The next six models in this guide are all from a series inspired by NASA’s plans for future and Mars programs, with designs that draw from serious concepts.
The Lego City Space Rocket Assembly and Transport is our favourite of them, because not only does it have the coolest-looking rocket (which is the most important thing), but we also love the big crane assembly and caterpillar transportation vehicle. And as a playset, the range of robots, vehicles, and garage gives loads of scope for little explorers to have fun.
This is a really fun selection of minifigures and accessories: it comes with seven different astronauts, a reporter, a camera operator, a personal trainer, a drone engineer, a rocket engineer, a mechanical engineer and a botanist, plus a robot, a g-force training machine, pizza, space rocks, a test rocket, and more. It’s a really cool set of stuff for kids to free play with and add to their range of other Lego.
This Lego City Mars Research Shuttle is a slick-looking shuttle that opens to reveal space for its two astronauts to sit plus a storage drone, perfect for carrying the included geode bricks. There’s also a rover with a grappling arm, but the little touch we love the most is the scanning heli-drone, which has a red panel that, when held over a brick of rocky regolith, will reveal a neat ‘scanning’ interface. It’s a great set for budding space scientists.
This is a concept for a small space station, with three modules to it that you can arrange however you like around the central airlock module. There’s a kitchen module, and living module, and a lab module, and they all open up so you can play with the minifigures included. The lab has light-up equipment, the kitchen has a pizza oven (we’re not sure of the NASA accuracy of that bit…), and the living area has a treadmill and bed. There’s also a small shuttle and a detachable satellite, for getting all that busy space work done.
The Deep Space Rocket Launch Control set has a multi-stage rocket with assorted modules, plus a control room for executing your perfect launches, but most importantly it has a funky rail transport system. There’s a range of accessories too, from transport vehicles on the ground to a robot help, to a space telescope satellite that fits in the rocket’s payload module for transport up to your ceiling. A nice added touch is that the control tower is designed to accommodate a phone with a special countdown app on the screen, for an atmospheric (so to speak) launch event.
You can practise for those martian/lunar escapades with this set. It has an articulated grappling arm and a removable cockpit plus chunky all-terrain wheels. There’s various rock collecting equipment for its driver minifigure to use when picking up the rock bricks it comes with, and it’s all observed by a technician.
