M01Project principlesDoctrine: core principles
Based on “Doctrine (core)” · Academy edition
Engineering serves the support of life, human comfort and a manageable relationship with the environment.
Light and living systems
Light is considered a factor in vision, biological rhythms and interaction with the environment. Mood, attention and subjective well-being are research topics. Each proposed effect requires defined conditions and a method of measurement.
Natural dynamics
Dawn, daytime, sunset, night, clouds and shadows provide a starting point for design. Spectrum, intensity, direction and distribution can change. The value of each pattern must be tested for the activity and person.
Spectrum and electromagnetic environment
The doctrine seeks a suitable spectrum and a controlled electromagnetic environment. This is a project principle. Turning it into a specification requires measurable quantities, operating limits and a review of applicable standards. “Full spectrum” alone does not establish quality or safety.
AI, person and physician
The person sets goals, reports comfort and retains control. The agent uses permitted data, proposes actions and explains them. A physician participates in clinical tasks and defines medical constraints. Predictive control must account for error and verify outcomes.
Goals and criteria
The project aims to reduce excessive strain and support sleep, performance and subjective well-being. These outcomes are assessed separately. Improvement in one does not establish improvement in the others.
Based on Take on light · 2 March 2025 · Academy edition
A lighting environment can respond to daily rhythm, activity, position and feedback. The concept connects sources, optics, controls and intelligence.
Rhythm and space
Design considers time and place: task surface, field of view, surrounding light, daylight and sleep conditions. Local lighting must work with contrast and visual comfort. Dimness is an intentional operating mode.
An artificial sky
The concept proposes directed and diffuse light, changing angles, cloud patterns and shadows. This is a research direction. Evaluation compares dynamic and baseline conditions while controlling illuminance, spectrum, glare and duration.
Families of light sources
Plasma, LED and other sources are assessed through measured properties of actual devices. Comparisons include spectrum, control, heat, noise, temporal modulation, maintenance and life. A technology label alone establishes no health advantage.
Power and fields
Wired power, batteries, a remote source and wireless power are engineering alternatives. Each requires assessment of losses, heat and electromagnetic fields during operation. Wireless transfer uses electromagnetic interaction; removing a cable does not remove the field.
Observation and prediction
Preferences and voluntary reports add to environmental data. Pulse, facial expression or activity do not uniquely determine emotions or the appropriate lighting. Models must express uncertainty, test predictions and allow an action to be cancelled.
Verification programme
A measured baseline, defined intervention, observation period and advance criteria are needed. Artificial skies, medical outcomes, new-source advantages and predictive control of personal state each need separate evidence. Prototypes are assessed through actual operation.
M03Research programmeTLI / TLB: scientific direction
Based on TLI-TLB · Academy edition
Lighting reform encompasses understanding, daily habits, environmental design and control methods.
Everyday life
Homes, workplaces, education, shops and the city form connected parts of a lighting day. The learning goal is to describe, assess and improve that routine together with an agent.
Population health
Sleep, attention, performance, stress and well-being are research topics. Immune and reproductive processes require separate research questions. Population conclusions require suitable study designs and control of other factors.
Deep space and extreme environments
The long-term question concerns light in a designed life-support environment. For the Academy this includes reconstructing a biome and maintaining connected life cycles. Practical models use known organisms and processes; obtaining life from non-living matter remains a separate scientific question.
Scientific organisation
AI supports search, memory, analysis and model comparison. A scientific team formulates questions, assesses evidence and verifies results. Electrical engineering, lighting, biology, environmental design and operations use a shared data framework.
Research and application
Deployment creates observations and questions. Research refines settings, equipment and quality criteria. Reproducible results gradually inform methods, teaching and practice. Scaling retains the boundaries of verified findings.
Based on the explanatory note on a unified lighting environment · Academy edition
A territory is considered through its combined light exposure: streets, transport, housing, workplaces and public spaces.
What is controlled
The scope includes sources, optics, power, controls, schedules and movement. Measurements describe actual outdoor and indoor conditions. Each system retains its responsible operator and operational constraints.
Coordinated settings
Control considers time, weather, presence and activity. Outdoor, transport and indoor lighting are coordinated where the task justifies it. Transitions preserve required visibility, manual control and recovery after failure.
Light, dimness and darkness
Managed darkness is part of the environment. Each setting requires an account of visibility, operating hours and light reaching neighbouring areas. Reduced intensity is supported by a survey and verification of conditions.
Renewal and reuse
Installation history covers inspection, cleaning, repair, adjustment, replacement and reuse of suitable equipment. Relocated devices require a fresh condition and suitability check. Renewal follows a measurable reason.
Diagnostics and feedback
Surveys, measurements and reports help identify conflicting settings. Changes are logged in the environmental passport. Before-and-after checks account for weather, season, traffic and activity.
Transfer between locations
The architecture can serve different territories. Dense cities, suburbs, mountain routes and polar sites have different requirements. Shared elements are data structure, quality verification, local responsibility and explainable control.
M05Space and habitable environmentsLight in spacecraft
Based on the technical review of 31 August 2026; sources checked on 15 September 2026 · Academy edition
Taking terrestrial life into space means understanding the conditions it needs. On a spacecraft, lighting must fit sleep, work, visibility, instruments and biological cycles. They become parts of one engineering task.
Avoid carrying accumulated engineering mistakes into space.

What should be reproduced?
Nature provides a starting point: day and night, direction, spectrum, shadows and gradual transitions. Design turns that example into testable requirements. Continuous bright light, spill into sleeping areas and controls that people cannot override deserve early attention. Benefits of a particular solution must be tested under stated conditions.
The ISS: a daily rhythm within an orbital rhythm
The ISS experiences roughly 16 sunrises per Earth day while its crew follows a GMT schedule. NASA’s Lighting Effects studied the switch to LEDs with adjustable intensity and colour. The ESA/SAGA Circadian Light cabin experiment followed a sleep schedule. Operational equipment and an experimental installation have different purposes and status.
JSC Lighting Lab works with lamps, cameras, glare and shadows, modelling orbital and surface environments. Its tools include Radiance and Zemax. For the Academy, this illustrates how scene calculations can be combined with measurements and human evaluation.
NASA-STD-3001, Volume 2, Revision F, dated 14 July 2026, includes circadian lighting specifications. Two parameters from Table 8.7-2 appear below. Application requires the full standard and measurement conditions.
At the cornea in the vertical plane; both conditions must hold together. These are specifications for NASA human-rated systems. Personal home recommendations require a separate assessment.
What the SpaceX concept shows
The supplied illustration shows extended lighting strips, pale surfaces and light around the compartment perimeter. These features allow discussion of placement and possible reflections. Assessment requires spectra, photometry, operating modes, eye positions, screen behaviour and emergency power. The review and image do not supply those data. A proposed lighting architecture can serve as a design assignment.
Three tasks in one spacecraft
People need visibility, comfort and lighting coordinated with their schedule. Cameras and navigation need discernible detail, controlled reflections and compatibility with imaging settings. Plants need their own lighting conditions. A shared model should account for each subsystem’s power and heat, light spill and failure behaviour. This is the Academy’s proposed engineering framework.
Plants and living light
NASA uses Veggie and Advanced Plant Habitat for plant research in controlled environments. UMAMI studies a squid and its luminous bacterial partners. Bioluminescence is part of the living system under investigation. These projects provide insufficient evidence to justify illuminating a crew compartment with living organisms.
Start with one autonomous compartment: define geometry, sources, schedules, human positions and system states. Compare modes, check light spill into sleeping areas, camera operation and manual override. Consider lighting alongside noise, air and temperature. Ground testing can reveal a mistake before it becomes part of a spacecraft.
