Project Hail Mary

Project Hail Mary is LEGO entering literary science fiction territory, and the build experience reflects the thoughtful, problem-solving spirit of Andy Weir's novel. At 830 pieces, this is a focused build that prioritizes precision over volume. The construction centers on the Hail Mary spacecraft - Dr. Ryland Grace's interstellar vessel - and the build progresses from the engine section forward through the fuel tanks, the central spine, and finally the forward crew module. Every phase of the build mirrors the ship's functional layout as described in the novel, which fans of the book will immediately appreciate.

The engine section establishes the build's engineering character early. The Astrophage drive that powers the Hail Mary is represented through a combination of trans-orange and trans-yellow elements clustered around a cylindrical core, creating a visual that suggests barely-contained energy. Moving forward, the fuel tank section uses large cylindrical elements connected to the central spine through structural brackets, and the build here is clean and satisfying in its mechanical logic. The crew module is the most intricate section, with interior detail visible through transparent panel elements that let you see into the lab and living quarters.

The build concludes with Rocky the Eridian - the alien companion who becomes the heart of the story. Rocky is a small but carefully designed brick-built figure that captures the character's spider-like form and xenonite tunnel habitat. Building Rocky is a brief but emotional moment for anyone who loved the novel. The display stand assembly rounds out the build, providing a stable base that presents the completed spacecraft at an angle suggesting flight. Plan for 4-6 hours of focused building time that will feel like time well spent.

The Hail Mary spacecraft presents unique design challenges that LEGO has solved with real ingenuity. The ship's profile in the novel is distinctive - a long, thin central spine connecting bulbous engine and crew sections, with fuel tanks arrayed around the middle. Translating this into a structurally sound LEGO model requires careful engineering, and the internal Technic framework that runs the length of the spine is impressively rigid for its slender proportions. The ship feels solid when handled, with no flex or wobble despite its elongated form.

The crew module construction is the technical highlight. LEGO has designed a sectional module with removable panels that reveal the interior layout - Grace's lab, the sleeping quarters, and the command area. The interior uses micro-scale furniture and equipment built from small tile and plate elements that suggest function at a scale where literal representation is impossible. The transparent panels that form the module's exterior walls use a clip-and-bar mounting system that allows them to be attached and removed without tools, enabling easy switching between exterior display mode and interior viewing mode.

Rocky's construction deserves special recognition for its economy and expressiveness. Using fewer than 30 pieces, LEGO has created a figure that is immediately recognizable to anyone who has read the novel - five-legged, rocky-textured, with the distinctive sensory cluster that serves as Rocky's "face." The xenonite tunnel that connects Rocky's environment to the crew module uses transparent tube elements that glow under UV light, a detail that adds display potential beyond standard shelf presentation. Fans of LEGO space builds like the Shuttle Carrier Aircraft (#10360) and the Star Trek Enterprise (#10356) will find the Hail Mary's engineering approach both familiar and refreshingly different.

830 pieces in a predominantly white, light grey, and dark grey palette with strategic accent colors. The color spread is typical of spacecraft builds - clean, utilitarian, technical. The white and light grey curved slope selection is solid, and the structural plate and brick inventory in neutral tones is always useful for architectural or vehicle MOCs. The Technic elements used for the internal spine provide a small but useful selection of axles, pins, and beam connectors.

The standout parts are the accent elements. Trans-orange and trans-yellow pieces used for the Astrophage drive are eye-catching and relatively uncommon in those quantities. The transparent panel elements that form the crew module walls are large, clear, and useful for any builder working on display cases, windows, or sci-fi MOCs. The display stand contributes black and dark grey structural elements in a clean, modern aesthetic. The printed elements include a nameplate tile and several small detail prints for the crew module interior. While the parts palette is not as colorful or exotic as some Icons sets, the selection is practical and versatile for builders who work in the neutral-tone space that most MOC builders inhabit regularly.

The Hail Mary spacecraft on its display stand is a striking piece of desktop or shelf art. The completed model measures approximately 40cm long, presented at an angle on its stand that suggests the ship in transit between star systems. The white-and-grey color scheme gives the model a clinical, NASA-adjacent aesthetic that reads as serious science fiction rather than fantasy space opera. The trans-orange engine glow at the rear provides the only warm color accent, drawing the eye to the propulsion system that drives the novel's plot.

Rocky's presence on the model adds an element of character that elevates the display beyond pure vehicle presentation. The Eridian figure and xenonite tunnel are visible on the ship's exterior, creating a focal point that tells a story even to viewers unfamiliar with the source material. For those who know the novel, Rocky's position on the ship is an emotional anchor that transforms the model from an interesting spacecraft into a representation of one of science fiction's most memorable friendships.

The display stand includes a printed nameplate that identifies the ship, the novel, and the author. This is a nice touch that connects the model to its literary origins and adds context for visitors who might not recognize the design. The overall display aesthetic is mature and understated - this is a set that looks at home in an office, a study, or a living room bookshelf without screaming "toy." Place it near the Blacktron Renegade (#10355) for a space-themed Icons display, and check our LEGO Display Ideas guide for more arrangement strategies.

At $99.99 for 830 pieces, the Project Hail Mary comes in at approximately 12 cents per piece. This is on the higher side for piece-to-price ratio, but the calculation does not capture the full picture. The model's 40cm length, the quality of the display stand, the inclusion of Rocky as a brick-built figure, and the removable crew module panels all add value beyond raw piece count. The build experience is engaging and the finished product is a display piece with genuine personality.

The emotional value for fans of the novel is significant. Project Hail Mary is one of the most beloved science fiction novels of the decade, and this is its first and likely definitive LEGO representation. The design captures the spirit of the story - the ingenuity, the isolation, the unlikely friendship - in a way that will resonate deeply with readers. For those unfamiliar with the source material, the set still works as a sleek, well-designed spacecraft model with an interesting alien companion, but the full impact requires knowledge of Grace and Rocky's journey.

The single minifigure - Dr. Ryland Grace in his EVA suit - is nicely detailed with printed torso and leg elements that reference the novel's descriptions. It is not a large minifigure haul, but for a set focused on a single character's story, one well-executed figure is the right choice. The overall package represents fair value for a licensed Icons set with strong display appeal and deep personal connection potential. It earns its place in our Best LEGO Sets for Adults 2026 guide as a standout for science fiction fans.

The set includes one minifigure: Dr. Ryland Grace, the reluctant astronaut and protagonist of Andy Weir's novel. Grace is presented in his EVA spacesuit with detailed torso printing that includes life support connections, mission patches, and suit paneling. The leg printing continues the suit design with additional technical detail. An alternate head with a different expression allows you to display Grace in either his determined mission mode or a more relaxed configuration. The helmet piece is a standard astronaut helmet with a clear visor, and an alternate hair piece is included for helmetless display.

Rocky the Eridian is not a minifigure in the traditional sense but deserves discussion alongside Grace. The brick-built Rocky figure uses approximately 25-30 pieces to create a five-legged alien with a rocky exterior texture and a cluster of sensory appendages. Rocky is small - roughly the same height as a standard minifigure - but the design captures the character's essential physicality with impressive economy. The figure is designed to be displayed within the xenonite tunnel section of the spacecraft, positioned as though communicating with Grace through the tunnel wall. Together, Grace and Rocky represent one of the most heartwarming relationships in modern science fiction, and LEGO has given both characters the attention they deserve.
