Oxygen extraction plant skid (Moon Base Colony and Lunar Rovers)
A 4.4 m process skid on bearing pads: two hydrogen reduction reactor vessels with support skirts, a cyclone separator, a helical condenser coil, gas pipework, a control cabinet and a rack of product gas bottles.
Regolith hopper and screening deck (Moon Base Colony and Lunar Rovers)
A 4.4 m feed hopper on four splayed legs over an inclined vibrating screen deck: nine screen bars, two shaker motors on spring mounts, a fines discharge chute into a spoil pile, an oversize chute, an access ladder and a walkway.
Pressurised workshop and vehicle bay (Moon Base Colony and Lunar Rovers)
A 9.4 m wide arched vehicle bay on a graded slab: a ribbed hard shell with a 5.2 m roll-up door on a named node, exterior workbench, gas bottle rack and two floodlights, and a hab-port spur on the port flank.
Regolith bucket drum excavator (Moon Base Colony and Lunar Rovers)
A 5.5 m four-wheel regolith excavator: a counter-rotating bucket drum with three rows of scoops on a hydraulic lift boom, a tipping spoil body, a drive cabinet and a suited operator station, all on wire-mesh wheels with steering uprights.
Airlock with dust-lock vestibule (Moon Base Colony and Lunar Rovers)
A two-chamber surface airlock on a raised plinth: a dust-lock vestibule with a hinged outer hatch and boarding ramp on named nodes, a five-nozzle dust removal rail, two rear-entry suit ports on the flank and a tunnel spur to the site grid.
Pressurised greenhouse module (Moon Base Colony and Lunar Rovers)
A 9.2 m barrel-vault growing module on a plinth: a ribbed transparent shell over three tiers of hydroponic trays and LED light bars either side of a central service spine, with hab-ports on both end walls.
Cupola observation turret (Moon Base Colony and Lunar Rovers)
A 7.6 m glazed watch turret on a column and plinth: a twelve-panel window drum under a conical dust roof, an external ground stair to a platform, a mast light and a tunnel spur back to the site grid.
Regolith shielded habitat (Moon Base Colony and Lunar Rovers)
An 8 m pressure shell buried under a 4.7 m graded regolith arch held by three retaining ribs and two horseshoe end walls, with only the end domes and their hab-ports left in the open.
Inflatable dome habitat with regolith shielding (Moon Base Colony and Lunar Rovers)
The dome habitat buried to the shoulder under a graded regolith berm and two courses of filled bags, the shielding fit used once a base moves from a short sortie to a permanent crew rotation.
Pressurised connecting tunnel, tee junction (Moon Base Colony and Lunar Rovers)
A three-way tunnel junction on a central ground column: a lens-shaped pressure vessel with a crown surface hatch, an access ladder and three hab-ports 3 m out on the fore, aft and starboard axes.
Rigid cylinder logistics module on legs (Moon Base Colony and Lunar Rovers)
The same legged pressure shell fitted out for stores: no viewports, external cargo racks and tie-down rails down both flanks and a dorsal equipment hatch.
Pressurised connecting tunnel, quarter turn (Moon Base Colony and Lunar Rovers)
A quarter-turn tunnel bay that swings the run through ninety degrees between two hab-ports 3 m from the corner, carried on two ground trestles.
Rigid cylinder crew habitat on legs (Moon Base Colony and Lunar Rovers)
An 8 m metal-shell crew habitat carried clear of the regolith on four splayed legs with wide footpads, with three viewports, a roof radiator strip, an access ladder and axial hab-ports at both ends.
Inflatable dome habitat (Moon Base Colony and Lunar Rovers)
A 7.2 m soft-goods dome habitat inflated over a rigid base ring, held by a meridian strap net and eight ground anchors, with a dust skirt, crown hatch and two side hab-ports.
Pressurised connecting tunnel, straight bay (Moon Base Colony and Lunar Rovers)
A 6 m straight surface tunnel bay on two ground trestles: a bellows-ribbed pressure sleeve on the 2.4 m port axis with hab-ports at both ends and handrails down both flanks.
Craft Lineup (UFO Crash Site and Recovery Facility)
Every recovered craft in the pack at true relative scale with a standing figure for reference: the 12 m saucer on its gear, the torn scout disc, the 16 m triangle behind them, the bio-organic pod, both states of the drone probe, the lifted engine core and the cutaway hull...
Connector Cases (UFO Crash Site and Recovery Facility)
Independent test assemblies covering all three port types: a furrow tile chained to an end tile and to burnt tiles on both sides on the ground grid, a cordon run turned through a corner into a second run, an open bay floor slab butted to two hangar bay sections closed by an...
Hangar Bay with the Saucer (UFO Crash Site and Recovery Facility)
A 12 m disc craft with its gear stowed, sitting on its cradle in a run of open bay floors with the hangar shell and gable wall closing the far end behind a twin leaf blast door. An overhead travelling crane spans the bay behind it and a wash-down bay closes the near end. An...
Crash Site at Night (UFO Crash Site and Recovery Facility)
A recovery in progress on open ground: a damaged scout disc lying in an 18 m impact crater at the head of a skid run of furrowed and burnt tiles, with hull fragments, a torn panel, a frame piece, a detached leg and two debris scatters strung back along the trench. A taped...
Crane banksman (UFO Crash Site and Recovery Facility)
A 1.8 m adult signalling a lift: high visibility vest with two reflective bands over dark working dress, a hard hat with a brim and chin strap, a radio on the chest and two lit marshalling batons, the right one raised and the left one lowered.
Containment Laboratory (UFO Crash Site and Recovery Facility)
The containment suite laid out on three open bay floors with the hangar gable wall closing the far end: two sealed cells with viewing windows at the head of the room, an empty specimen tank beside one holding an abstract suspended mass, an examination table under its lamp, a...
Hazmat scientist (UFO Crash Site and Recovery Facility)
A 1.8 m adult standing in a sealed protective coverall: a hood with a clear visor and chin seal, a back-mounted respirator with its breathing hose, a utility belt, taped cuffs and a hand scanner held in both hands. No badge, insignia or agency identity.
Technician with a tablet (UFO Crash Site and Recovery Facility)
A 1.8 m adult in a light coverall, turned slightly and reading a tablet held in both hands: safety glasses, a lanyard with a blank card, a pen pocket and a tool roll on the hip.
