Five domains inside LUNA. A planned program is still a public research question. No program is a completed habitat design.
VL-PROG-HABACTIVE
Lunar Habitat Structures
How can pressure-shell, buckling and buried-shell screening be made traceable enough to support later design-level structural workflows?
- Classical thin/thick pressure-shell relations are implemented as screening kernels.
- Preliminary classical buckling screening exists; knockdown and imperfection sensitivity are not closed.
- No qualified habitat design method is claimed.
Models: VL-MOD-PSH-001 · VL-MOD-PSH-002 · VL-MOD-BCK-001 · VL-MOD-BRI-001
Gaps: VL-GAP-006 · VL-GAP-007
Implementation: Pressure-shell kernels implemented; buckling and buried-shell interaction remain screening-level.
Validation: Screening only. Planned analytical comparisons are recorded in VL-BENCH-001 and have not been run.
VL-PROG-REGACTIVE
Regolith Geotechnics
Which continuum screening models for density, overburden and lateral pressure can be justified before site-specific and low-gravity constitutive data exist?
- A density-depth working model and overburden integration are implemented.
- K0 / Rankine screening is used as a bound, not as unique physical truth.
- South Pole stratigraphy, ice content and low-gravity constitutive behaviour remain open.
Models: VL-MOD-REG-001 · VL-MOD-REG-002 · VL-MOD-GEO-001 · VL-MOD-BRI-001
Gaps: VL-GAP-001 · VL-GAP-002 · VL-GAP-003 · VL-GAP-006
Implementation: Density-depth, overburden and Rankine/K0 screening kernels are implemented.
Validation: Screening only. No site-specific geotechnical validation is claimed.
VL-PROG-ISRUPLANNED
Lunar Construction Materials / ISRU
What evidence is required before sintered or process-route regolith products can be treated as structural materials rather than research concepts?
- No Vectoris structural allowable set exists for ISRU products.
- VL-SRC-001 records community practice on simulants and sintering as context only.
- Qualification of ISRU materials is an open gap.
Models: none implemented
Gaps: VL-GAP-004
Implementation: No ISRU constitutive or allowable kernel is implemented.
Validation: Not started as a materials qualification program.
VL-PROG-THMACTIVE
Lunar Thermal & Environmental Engineering
How should vacuum, thermal cycling and environmental loads be introduced into structural screening without implying a qualified thermal-control design?
- A lunar gravity / environment baseline is implemented for screening.
- Preliminary thermal and transient wall models exist at screening status.
- Integrated thermal-structural validation is not closed.
Models: VL-MOD-ENV-001 · VL-MOD-THM-001 · VL-MOD-THM-002
Gaps: VL-GAP-009
Implementation: Environment baseline implemented; thermal kernels remain screening-level.
Validation: Screening only. Coupled thermal-structural benchmarks are not published.
VL-PROG-SURPLANNED
Lunar Surface Infrastructure
Which surface-system loads (plume, ejecta, MMOD, landing proximity) can enter a structural workflow only after dedicated models and evidence exist?
- No LUNA plume, MMOD or landing-load kernel is implemented.
- These topics are recorded as open model and data gaps.
Models: none implemented
Gaps: VL-GAP-007 · VL-GAP-008
Implementation: No surface-infrastructure load kernels implemented.
Validation: Not started.
