Ships

Block-built spacecraft with sealed, walkable interiors: block icons, stats and costs generated from game data.

A 40-block cruiser in flight: two decks, bulkheads with airlocks, engine gondolas firing.

Engine room and fuel bay: generators, battery racks, cryogenic H₂ tanks, gyroscopes on the upper deck.

The bow: glazed cockpit with the pilot seated at the console, armored keel, technical section.

How to build a ship, step by step

Unlock Ships in the research tree, then press K (or Inventory → „Block ship") to open the ship builder.
Start with the Cockpit: it is the core of the ship (one per ship). Every other block must touch an existing block.
Lay the keel and hull. LMB places the selected block, RMB removes one (refunds 50 % of materials). Blocks cost materials from your backpack.
Mount Thrusters under the hull (nozzle down = main lift). R rotates the nozzle while placing: side nozzles give lateral thrust, up gives retro. Every thruster needs a straight exhaust path.
Add H₂ tanks, a Gyroscope (rotation), Landing gear (soft touchdown) and a Battery + Solar panel for onboard power.
Seal the interior: full shell of hull blocks + a Door (airlock). The game detects the hermetic interior automatically: install a Life support module with power and water and the inside fills with breathable air.
Fuel up: place a Refuelling coupling touching the hull; park the ship so the coupling touches a pipe, tank or electrolyzer with hydrogen: it pumps 0.5 kg/s into your tanks.
Board with E at the cockpit: the pilot sits down visibly at the console. Passengers board passenger seats the same way (co-op).

Flight controls

Key	Action
`W` / `Space`	main thrust (all down-facing nozzles)
`A` / `D`	lateral thrust (side nozzles), wheels drive on the ground
`S`	retro thrust (up-facing nozzles)
`Q` / `E`	rotate the ship (needs a gyroscope and battery power)
`E`	board / leave (short press at the cockpit or a seat)
`LMB`	mining ship: run the drill (block „Mining drill", 1.5 kW)

Climb above 240 m with positive vertical speed and you reach orbit: the system map opens and you can travel to other planets. Fuel is real: check the burn rate of your nozzles in the table below.

Land, sea and air vehicles

Wheels drive on terrain using battery power: no fuel needed. More wheels = more force. Rovers and mining crawlers are ships too.
Atmospheric rotors fly on electricity; thrust depends on air density: cheap planetary flight, useless in vacuum.
Wooden hull + floats make boats: floats triple buoyancy; a paddle wheel or rotor propels them.

The interior is real simulation space: temperature, air and pressure are tracked. A closed hull with life support protects you from vacuum, toxic atmospheres and solar storms: your ship is a flying base with an onboard furnace, cargo holds and a water recycler.

All 27 ship blocks

Block	Mass	Stats	Cost	What it does

Cockpit	200 kg	200 Wh	Steel plate 4 kg Integrated circuit 1 kg Glass 2 kg	The ship's core: one per ship, start here. Seat, controls, camera. 200 kg.
Thruster	150 kg	thrust 9 kN	Steel plate 3 kg Electric motor 1 kg	Hydrogen rocket engine: 9 kN of thrust, 30 g H₂/s. Nozzle down = thrust up (W); sideways = manoeuvre (A/D); up = retro (S). [R] rotates while placing. 150 kg.
H₂ tank	90 kg	40 kg H₂	Steel plate 3 kg Steel 2 kg	40 kg of hydrogen per block. 90 kg empty.
Gyroscope	130 kg		Steel plate 2 kg Electric motor 1 kg Integrated circuit 1 kg	Reaction wheels: let you rotate the ship (Q/E) and stabilise flight. More gyros = faster rotation. 130 kg.
Landing leg	80 kg		Steel plate 2 kg Steel rod 2 kg	Damped landing leg: soft touchdown, stable parking, slow self-levelling. 80 kg.
Cargo hold	110 kg	cargo 1500 kg	Steel plate 4 kg Structural frame 1 kg	1500 kg of storage per block: [E] next to the ship opens the transfer panel. 110 kg empty.
Refuelling coupling	90 kg		Steel plate 2 kg Steel 1 kg Copper 1 kg	Fuel port: when the ship is parked and a pipe, tank or electrolyser with hydrogen sits below/next to the coupling, H₂ flows into the ship's tanks (0.5 kg/s). This is how you refuel from your own production.
Battery	180 kg	5000 Wh	Steel plate 2 kg Copper 3 kg Integrated circuit 1 kg	5 kWh of energy for gyros and the drill. Charged from solar panels. The cockpit has its own 200 Wh.
Solar panel	60 kg	600 W solar	Glass 3 kg Integrated circuit 1 kg Copper 1 kg	600 W in full sunlight (less at night/underground). Charges the ship's batteries.
Large thruster	400 kg	thrust 27 kN	Steel plate 8 kg Electric motor 3 kg Steel 4 kg	Large hydrogen engine: 27 kN of thrust, 90 g H₂/s. Heavy (400 kg), for big ships. [R] rotates the nozzle.
Mining drill	220 kg		Steel 4 kg Electric motor 2 kg Steel plate 2 kg	Mining ship: in flight LMB drills a 1.6×1.6 m area in front of the bit ([R] rotates it), the yield goes into the hold. Draws 1.5 kW from the battery.
Passenger seat	60 kg		Steel plate 1 kg Steel rod 1 kg	A place for a crew member (co-op: the second player boards with E at the seat and rides along). A crewed ship = seats + life-support module.
Life-support module	160 kg		Steel plate 3 kg Integrated circuit 2 kg Steel 2 kg	O₂ generator + CO₂ scrubber: the inside of a sealed hull (enclosed by blocks, doors shut) holds breathable air. Draws 300 W and 1 g of water/s from the hold.
Airlock (door)	50 kg		Steel plate 2 kg Electric motor 1 kg	Hull door: E next to it opens/closes. Shut = a wall (airtight), open = the interior loses its air.
Heavy armour	320 kg		Steel 4 kg Steel plate 2 kg	A thick steel plate: survives hard landings and impacts (block damage, v2.1). 320 kg.
Large hold	300 kg	cargo 4500 kg	Steel plate 8 kg Structural frame 3 kg Steel 2 kg	4500 kg of storage per block: for freighters. Unloaded through a coupling next to a crate.
Large H₂ tank	260 kg	160 kg H₂	Steel plate 6 kg Steel 6 kg	160 kg of hydrogen: interplanetary range for large ships.
Onboard generator	150 kg	2000 W	Steel plate 2 kg Electric motor 1 kg Copper 2 kg	Burns hydrogen from the tanks (0.05 g/s) → 2 kW into the battery. Power at night / underground for the drill, gyros and life support. 150 kg.
Water tank	120 kg	cargo 200 kg	Steel plate 3 kg Steel 2 kg	200 kg of water for life support and crew (the coupling loads water from a tank/pipe next to the ship; panel: "Water into the suit"). Without it, life support draws from the hold (50 kg).
Water and CO₂ recycler	160 kg		Steel plate 3 kg Integrated circuit 2 kg Copper 2 kg	Recovers water vapour and CO₂ from the cabin: life support uses 10× less water (+150 W). Long flights and base-ships without refilling water.
Fluid hold	220 kg	cargo 500 kg	Steel plate 5 kg Steel 4 kg	500 kg of liquid/gas (oil, water, oxygen, kerosene, acid…). Coupling next to a tank: LOAD mode takes from the tank, UNLOAD gives back (ship panel). Fluid transport between bases and planets.
Wooden hull	45 kg		Wood 6 kg	Planks on ribs: a light, cheap all-wood hull for boats and first vehicles. Floats better than steel (45 kg instead of 120 kg), but does NOT hold vacuum and burns in fire.
Drive wheel	70 kg		Steel plate 2 kg Electric motor 1 kg Steel rod 1 kg	WHEELED drive: drives over terrain on battery power (no rocket fuel). A/D to move, climbs slopes, brakes by itself. More wheels means more force, mining vehicles and rovers. On water it acts as a paddle wheel (slower).
Atmospheric rotor	120 kg		Steel plate 3 kg Electric motor 2 kg Integrated circuit 1 kg	ATMOSPHERIC drive: an electric propeller whose thrust depends on air density, cheap flight around a planet WITHOUT burning hydrogen. Useless in vacuum (rocket engines needed there). W/S up-down, A/D sideways.
Float (keel)	60 kg		Wood 4 kg Steel plate 1 kg	Buoyancy chamber: 3× more lift than a normal block and less rolling in waves. A wooden hull plus floats makes a boat; drive it with a paddle wheel or a rotor.
Ship furnace	300 kg		Steel 4 kg Steel plate 4 kg Integrated circuit 1 kg	The ship's electric furnace: smelts ores FROM THE CARGO HOLD (up to 1900 K, iron, copper, glass, silicon, steel); the product goes back to the hold. Ore reduction consumes coal/coke from the hold. 6 kW of ship power, 0.25 kg/s. The heart of a mobile base.
