Lego Project Hail Mary review: Amaze, amaze, amaze!
Given how much I enjoyed the Project Hail Mary movie, I was beyond hyped to get my hands on the Lego Project Hail Mary set. And now that I've built it, I'm thrilled to say it does not disappoint. You could even say that it's amaze, amaze, amaze!
The titular Hail Mary is the spaceship from "Project Hail Mary", the Andy Weir novel-turned-Hollywood blockbuster that carries Ryland Grace (Ryan Gosling) across the stars to save humanity. While the design of the ship is certainly described in the book, this is definitely a Lego rendition of the movie version. So, if you're an Andy Weir fan who imagined it looking a little different, you can blame the studio.
Coming in at $99.99 with just under 900 pieces, it's a lot smaller than we expected (and hoped for). If you're after something comparable to the hefty NASA Artemis Space Launch System or gargantuan Venator-Class Republic Attack Cruiser sets, then you'll be disappointed. However, the Lego Project Hail Mary has a heck of a party trick to make up for its diminutive size: A spinning mechanism that simulates the centrifugal gravity system of the ship.
Price: $99.99/£99.99
Model number: 11389
Number of pieces: 830
Dimensions: 12 x 9.5 x 8.5 inches / 30 x 25 x 22 cm
Recommended age: 18+
Lego Project Hail Mary review: Build




The Lego Project Hail Mary is constructed from 830 pieces, split across six numbered paper bags, with a few large pieces in a separate plastic bag. I built the kit over the course of two nights, but you could easily smash it out in a single evening if you wanted to.
The build starts with a little diorama, showcasing the Ryland and Rocky minifigures on either side of a window (the barrier that separates them when they first meet and learn to communicate in the movie). It's a cool little display that can work well on its own or can be attached to the stand of the ship itself.
From there on, four out of the six bags are almost entirely dedicated to the display stand and the incorporated spinning mechanism, with the final section of bag four attaching the ship’s crew module to the spinning mechanism. Thanks to the intricate mechanism inside it, the stand not only spins, but also retracts and extends the crew section of the ship, simulating the centrifugal gravity system from the movie. While it's a complicated mechanism that means a lot of Technic pieces, but the build itself is straightforward thanks to the clear instructions.
At last, the final two bags will see you constructing the ship itself. This consists of the main body where the thruster is housed, the three fuselage sections, and the solar panel array that provides power to the ship. Some builders might be disappointed that the actual spacecraft is a remarkably small part of the build process, but I think the spinning display stand is cool enough to offset that. Also, there are no stickers, which is always a huge win for me.
Lego Project Hail Mary review: Design









As I mentioned earlier, the display stand is surprisingly hefty and draws the eye away from the beautiful ship – a bit more than you might want from a display piece. That's the downside, but the upside is that it's an awesome party piece. Turning the handle on the front of the stand in either direction rotates the entire ship, simulating its spin in the movie. If you turn the handle clockwise, the crew module extends outward, while turning it counterclockwise retracts it.
The ship itself is a great recreation of Grace's eponymous craft, the Hail Mary. It's quite small, as Lego spaceships go, so there are no interior details or easter eggs hiding within the construction. Despite that, it captures the distinctive silhouette of the craft well, and includes all the major details, like the astrophage-powered engines that make the whole mission possible. From the three main pillars of the ship, which are the fuel tanks that store the astrophage, to the solar panel arrays that stick out from the main body, it all looks great.
I really love the little mini-diorama scene that you can create between Grace and Rocky, recreating their tentative first contact. It's a clever bit of design too, as you can attach their individual plinths to the main display and tuck the glass divider away in the stand. The minifigures themselves are great too. Grace has a custom red NASA flight suit, while Rocky is barely a minifigure — he's an eccentric collection of pieces mashed together, but I can't deny the end result is unmistakable Rocky.
Should you buy the Lego Project Hail Mary?

Overall, the Lego Project Hail Mary is a wonderful set that should thrill fans of the movie (more so than fans of the book, although I’m sure they’ll enjoy it too). The ship looks fantastic, and the spinning mechanism is wonderful to see in motion. There are actually some enterprising companies out there selling motorized mod kits for it, which is something I'm seriously considering checking out myself.
With that said, the prominent nature of the stand and somewhat gimmicky spinning feature does limit its appeal as a display model. Plus, those who aren’t big into technic-like builds may want to pass on this one and just admire it from afar.
Finally, while the build itself is only suitable for older teens and adults due to the complex nature of the internal workings, the finished model will definitely delight younger kids thanks to the interactivity it offers.

Lego deploys Hubble Space Telescope as detailed desktop model
For 35 years, the Hubble Space Telescope has looked out into the Universe. Now, Lego is inviting builders to look inward with its latest model of the orbiting observatory.
The new Lego Icons Hubble Space Telescope (set no. 11382) was released on August 1 for $140 at the toy company's stores and its online shop. The 1,252-piece kit builds a 15-inch-long (38-cm) desktop model that is about twice as large as the previously released Lego Hubble models.
The Icons Hubble is the first to be sized in comparison to a Lego minifigure, such that the included astronaut provides a sense of scale for the telescope.

‘The language of Pokémon is universal’: why fans are still catching ‘em all after 30 years
As Pokémon Go celebrates its 10th anniversary, its devoted players explain how the game has created a vibrant intergenerational community spanning the globe
Most Pokémon obsessives count rare, absurdly expensive playing cards or pristine, fully boxed game cartridges that have survived decades in the attic among their most prized possessions. But for Mairead Ralph, her Pokémon-related crown jewel is a bit different. “Technically, it’s my husband!” she says.
The pair first locked eyes amid decks of Pokémon playing cards and Pokéballs at a fan event 16 years ago and the rest is history. Ralph was among hundreds of Pokémon fans who flocked to Shoreditch, east London, on Saturday afternoon for a pop-up celebrating the 10th anniversary of Pokémon Go, the massively successful augmented reality smartphone game that has seen millions of players physically venture to all corners of the earth to catch ’em all in person. In that spirit, the surrounding area was full of Pokéheads wandering the streets, their heads in their phones, seeking to catch exclusive Pokémon that had been released.

- Our favorite space and sci-fi Playmobil sets: From Star Trek playsets to ESA-collaborated models
Our favorite space and sci-fi Playmobil sets: From Star Trek playsets to ESA-collaborated models
Playmobil is known for crafting imaginative playsets, taking kids (and adults) on big adventures from the comfort of their homes. When it comes to the exploration of space, they've got a lot to offer. Not only has Playmobil created two mega Star Trek sets, releasing the Playmobil USS Enterprise long before LEGO released its own version and the Playmobil Klingon Bird of Prey back in 2023 (both of which we've reviewed and loved), but they've even collaborated with the real-life European Space Agency (ESA).
As Nadia Lüders, ESA's partnership and brand licensing officer, said in a statement: “This partnership ensures that the curiosity and wonder of space continue to spark young imaginations — nurturing a new generation ready to explore, innovate and shape the Europe of tomorrow.”
Playmobil's dedication to weaving space exploration and learning into imaginative play is demonstrated in the sheer amount of space and sci-fi sets they have to offer, of which we'll jump into all 13 of them below. Ranging in price from the Playmobil Space Ranger for $15 to the Star Trek USS Enterprise for $354, there are playsets for a range of ages, interests, and budgets.
Not a fan of Playmobil, or can't find the right set? We've also rated and ranked the best Lego Star Wars, Lego space, and Lego Marvel sets you can buy.
The best Star Trek Playmobil sets we recommend 2026
Playmobil USS Enterprise

USS Enterprise
A sizeable Playmobil model of the original Enterprise, a treat for TOS fans.
Age rating: 10+ | Pieces: 150 | Figures: 6 | Dimensions: 39.4 x 18.9 x 13.4 in (100 x 48 x 34 cm) | Weight: 4.72 kg (10.4 lbs)
Playmobil launched the Star Trek USS Enterprise years ahead of LEGO’s November 2025 release date, and it made us ask the question: Playmobil versus Lego, which is the best USS Enterprise set? For starters, the Playmobil set comes in cheaper. And while it’s got 150 pieces in comparison to Lego’s 3,600, it’s still a lot bigger, measuring over 3 feet (1 meter) in length.
When our expert testers gave the Playmobil Star Trek USS Enterprise a full review, it earned a whopping 4 ½ stars, delighting with its authentic light and sounds, and an ease of build that results in a gorgeous replica. Yes, it’s expensive and it has a lot of stickers, but if you’re a fan of both Star Trek and Playmobil, it’s an excellent model you can keep in your home forever. Recommended for ages 10 years and up.
Playmobil Klingon Bird of Prey

Klingon Bird of Prey
This set is considered a collectable but it's worth tracking down
Age rating: 10+ | Pieces: 94 | Figures: 6 | Dimensions: 19.5 x 23 x 7.25 in (49.5 x 58 x 18 cm) | Weight: 4.4 lbs (2 kg)
Playmobil followed up its Star Trek USS Enterprise with another impressive model, the Klingon Bird of Prey. Now considered a collectible, it’s a little harder to get your hands on, though we found it at an online toy store for $350.
If you’re wondering whether it’s worth the investment, in our expert Playmobil Klingon Bird of Prey review, we called this set “among the most impressive toys and models Space.com has had the pleasure of reviewing.” Impressive detail, great lights and sounds, and figurines that are a lot of fun are just some of the reasons we gave it 4.5/5 stars. And after the build is done, it looks fantastic on its included display.
It’s on the larger side, though (19.5 x 23 x 7.25 inches / 50 x 58 x 18 cm), so make sure you have room to display it before you buy. Recommended for ages 10 years and up.

- Monthly Roundup: The Fourth Catalog of Gravitational Wave Events from LIGO, Virgo, and KAGRA
Monthly Roundup: The Fourth Catalog of Gravitational Wave Events from LIGO, Virgo, and KAGRA
![]()
A recent Focus Issue of the Astrophysical Journal Letters describes the fourth version of the catalog of gravitational wave events (GWTC-4.0) from the Laser Interferometer Gravitational Wave Observatory (LIGO), the Virgo interferometer, and the Kamioka Gravitational Wave Detector (KAGRA).
This catalog contains transient gravitational wave events recorded through January 2024, during the observatories’ fourth observing run, which concluded in November 2025. GWTC-4.0 displays the results of significant improvements to our suite of gravitational wave detectors, including higher-powered lasers and reduced quantum noise. A fifth catalog of gravitational wave events was released in Spring 2026, with the accompanying scientific articles being submitted to the Astrophysical Journal and the Astrophysical Journal Letters.
This Monthly Roundup consists of short descriptions of each of the currently published research articles in the LIGO–Virgo–KAGRA Gravitational Wave Transient Catalog (GWTC): Release 4 Focus Issue. Each snippet links to the corresponding research article, and the Focus Issue landing page is linked at the bottom of this post. Be sure to revisit the landing page to catch new articles as they’re published!
Introducing GWTC-4.0
First up, the collaboration orients the reader to many important aspects of the catalog and the articles contained in the Focus Issue. This article describes how four detectors, each with two arms 3–4 kilometers long, monitor gravitational waves from Hanford, Washington; Livingston, Louisiana; Santo Stefano a Macerata, Italy; and Hida, Japan. These detectors work in concert, ready to receive signals from the universe during coordinated observing runs separated by periods of downtime for construction and commissioning. During these pauses, a smaller instrument, the German–British GEO600 gravitational wave detector, has kept an ear out for signals and will continue to do so until the end of 2026.After these detectors record subtle spacetime squiggles from compact objects colliding millions to billions of light-years away, the collaboration converts the raw signals into the data contained in catalogs like GWTC-4.0. This process involves modeling the gravitational wave signals, filtering them to identify candidate transients, and pinpointing the most significant events.
After collecting and cleaning the signals, the collaboration undertakes a critical step: making their data accessible to researchers and the public. The data are available through the Gravitational Wave Open Science Center, and the Focus Issue article on open data describes how to navigate the online portal, how the datasets archived online are structured, and how the data were calibrated.
Science Results
This fourth version of the gravitational wave transient catalog greatly expands the sample of gravitational wave transients recorded by detectors across the globe. Including events from previous catalogs, GWTC-4.0 brings us to 218 events for which the probability of the source being astrophysical in nature is more than 50% and for which there is little chance of the signal being an instrumental artifact. This represents a more than 100% increase in the number of recorded gravitational wave events fulfilling this criterion, broadening our understanding of colliding compact object pairs. This release also includes some superlative signals, such as the most massive black hole binary with a low false-alarm rate and the highest signal-to-noise ratio for a gravitational wave event thus far.
Detected in November 2023 by both LIGO Hanford and LIGO Livingston, GW231123 is in many ways an exceptional gravitational wave transient. The total mass of the merging components appears to be between 190 and 265 solar masses, and the false-alarm rate for this signal is less than one per year. This makes it the most massive merger event with such a low false-alarm probability. The two components also appear to have high spins, which complicates the interpretation of the signal with existing models. A binary black hole merger in which one or more components lies within the pair-instability mass gap is the likeliest explanation for this signal, but the authors also present alternative scenarios, such as a core-collapse supernova or a gravitationally lensed gravitational wave signal.

Baidu’s Apollo Go begins London robotaxi testing with Uber and Lyft
Baidu’s Apollo Go started robotaxi road testing in London today, and it’s doing it with both of ride-hailing’s biggest names at once — Uber and Freenow by Lyft.
The launch lands days after Apollo Go ran the first fully driverless trial in any right-hand-drive market, in Hong Kong. Two milestones in one week, on opposite ends of the world.
