Project Summary

Our mission is to create a compact, autonomous, and reliable ecosystem capable of ensuring the survival of astronauts during critical phases of a mission โ€” and beyond. At the heart of this system is our modular incubator: a robust, self-contained growth chamber designed to thrive in the harsh conditions of space.

Key Innovation

Highly durable, watertight, and extremely compact. Fully disassemblable โ€” individual components can be repaired or replaced without compromising the entire system. Supports both terrestrial and aquatic plant species. A life-support module in the form of a garden, built for long-term deep-space exploration.

๐Ÿ”ญ Part 1 โ€” What is our incubator?

Robigus incubator main render
What is it?
A modular space incubator designed to grow plants โ€” including aquatic species โ€” aboard spacecraft and space stations. It supports the crew's nutrition, air quality, and psychological wellbeing.
Why does it matter?
Long missions require self-sufficiency. Growing fresh food on board reduces launch mass, extends mission duration, and provides a biological supplement to mechanical life-support systems.
๐Ÿ”ง
Modular & Repairable
Easily disassembled into independent sections. If one compartment fails, it can be swapped without affecting the rest. No specialist tools needed.
๐Ÿ’ง
Watertight Design
The sealed, watertight shell enables hydroponic and aquaponic cultivation, dramatically expanding the range of organisms that can be grown in orbit.
๐Ÿ›ก๏ธ
Extremely Durable
Built to withstand launch vibrations, pressure changes, and temperature fluctuations. The hexagonal lattice structure distributes mechanical stress efficiently.
๐Ÿ“
Compact Footprint
Minimal space taken up aboard the spacecraft. Every cubic centimeter is at a premium on a rocket โ€” the incubator is designed with this constraint front of mind.
๐ŸŒฌ๏ธ
Air & Water Recycling
Plants absorb COโ‚‚ and release Oโ‚‚. Hydroponic cultivation uses up to 90% less water than traditional agriculture. Excess moisture can be captured and reused.
๐Ÿง 
Psychological Support
Research from NASA and ESA shows that caring for living plants measurably reduces stress levels and improves mood โ€” a piece of home for the crew.

Component 1 โ€” hexagonal frame
Component 1
Load-Bearing Shell (Hexagonal Frame)
The structural core of the incubator is a cylindrical shell with a hexagonal lattice pattern inspired by honeycomb geometry. The hexagonal design is not merely aesthetic โ€” it is the geometrically most efficient shape for distributing mechanical stress. The frame connects all other components and forms the backbone of the entire system. Material: steel. Function: Supports and joins the lids, side panel, and inner container. The open lattice structure allows light to pass through and air to circulate around the plants.
Component 2 โ€” bottom lid
Component 2
Bottom Lid (Base)
The bottom lid forms the foundation of the incubator. Three legs provide stable anchoring on any surface โ€” whether a table, shelf, or rail inside the spacecraft. The ends of the legs have holes for bolts, which are used to screw the entire assembly firmly to the surface. This keeps the incubator securely fixed even during launch vibrations or spacecraft manoeuvres. Function: Base and anchor point for the whole assembly. Houses the inlet for the irrigation system or root substrate.
Component 3 โ€” top lid with valve
Component 3
Top Lid with Valve
The top lid seals the incubator from above and features a key element โ€” a circular outlet port with a valve. This valve allows safe filling and draining of water or nutrient solution without disassembling the incubator. Tabs around the rim ensure a secure grip and easy twist-open access. Function: Hermetic closure from above plus safe access to the water system without full disassembly. Critically important in microgravity, where free-floating water poses a serious hazard.
Component 4 โ€” side technology panel
Component 4
Side Technology Panel
The side panel is the functional heart of the incubator. It houses LED lighting that simulates the solar spectrum and a heating system that maintains optimal growing temperatures for the plants. The panel is slide-out โ€” in the event of a failure, it can be removed and replaced within minutes without disturbing the rest of the system. Function: Provides artificial light and heat. The slide-out mechanism enables maintenance without full disassembly.

๐Ÿง  Part 3 โ€” How the Incubator Works

Terrestrial plants
โ€ขLettuce, spinach, rocket โ€” fast growth, high Oโ‚‚ output
โ€ขRadishes, chives โ€” space-efficient and low-maintenance
โ€ขCherry tomatoes โ€” a fruiting component for crew nutrition
Aquatic & hydroponic plants
โ€ขDuckweed (Lemna minor) โ€” extremely rapid growth, doubles every 24โ€“48 hrs
โ€ขSpirulina โ€” protein-rich microalgae, ideal dietary supplement
โ€ขHydroponic lettuce โ€” substrate-free, cleaner operation
Oxygen production estimates

An average plant leaf produces approximately 5 ml of Oโ‚‚ per hour. A healthy houseplant can produce 3โ€“9 litres per day, depending on leaf surface area and light intensity.

ScenarioNo. of plantsOโ‚‚ output / day
Hydroponic lettuce5 plants~15โ€“25 litres/day
Duckweed (dense culture)โ€”~30โ€“50 litres/day
Mixed culture (plants + algae)4 + algae~35โ€“60 litres/day

NASA states the average astronaut consumes ~0.84 kg of Oโ‚‚ per day (~589 litres). A single incubator covers roughly 5โ€“10% of that daily requirement. A fleet of 10โ€“20 incubators could provide meaningful oxygen support for the entire crew.

Robigus ยท Mission Explained
๐ŸŒฑ
Crew Food Self-Sufficiency
Long space missions โ€” such as the Artemis program or planned flights to Mars โ€” last months or even entire years, far from Earth. Food supplies launched from the surface are heavy, bulky, and have a limited shelf life. Every extra kilogram means enormous rocket launch costs. Our incubator solves this problem at the source โ€” it allows the crew to grow fresh plants directly on board the spacecraft or station. Astronauts can access nutritious, fresh food on the other side of the solar system, without waiting for resupply missions from Earth. This fundamentally extends the maximum possible mission duration and reduces the overall mass requirements of the mission.
๐Ÿ’จ
Air and Water Recycling
Plants are not just food โ€” they are living life support systems. During photosynthesis, they naturally absorb carbon dioxide and release oxygen, which is absolutely critical in the enclosed environment of a spacecraft. The more plants the crew grows, the less they need to rely on mechanical air filtration systems. The watertight design of our incubator also enables hydroponic and aquaponic growing โ€” without soil, purely in nutrient-enriched water. This approach uses up to 90% less water than traditional agriculture. Excess moisture exhaled by the plants can be captured, filtered, and reused as drinking water or for further irrigation. The incubator thus becomes part of the ship's closed biological cycle.
๐Ÿ”ง
Modularity = Reliability in Extreme Conditions
In space, you cannot call a repair technician. If something breaks, the crew must manage on their own โ€” with whatever they have available. That is exactly why our incubator is designed as a modular system made up of independent sections. If one compartment fails, the crew simply disconnects it, replaces it, and the rest of the incubator continues operating without interruption. No specialized tools or technical expertise are required for repairs.
๐Ÿง 
Psychological Benefits for the Crew
Space is an inhospitable, silent, and isolated environment. Astronauts spend months cut off from their families, nature, and normal everyday life โ€” and this takes a toll on their mental wellbeing. Research from both NASA and ESA consistently shows that caring for living plants measurably reduces stress levels, improves mood, and strengthens a sense of purpose in daily routine. The color green, the scent of fresh herbs, and the tangible result of one's own work โ€” these are things that have an enormous psychological impact in an environment of absolute sterility.
๐Ÿ”ด
Preparing for the Colonization of Mars
The incubator is not just a solution for today โ€” it is a testing ground for tomorrow. Every mission in which our system is used will generate valuable data on how plants respond to reduced gravity, increased radiation levels, and extreme temperature conditions. These findings are irreplaceable for designing future Martian greenhouses, underground agricultural halls, or biosystems for a permanent lunar base. Mars has no magnetic field or dense atmosphere to shield against cosmic radiation โ€” and understanding how plants survive and grow under such conditions is a key step toward humanity one day becoming a truly interplanetary civilization.
