Where LUCI’s runs sit in condition space, in the Atlas chart window. Other investigations’ runs in this regime are dimmed.

2 of 2 runs drawn.

Source: NASA PSI run tables (snapshot 2026-11-14) and the published papers listed under Sources. Evidence proximity, not a safety rating; not a hazard map.

Objective

No objective text; see the source document.

Fingerprint COMPUTED

Computed from the 2 records below: what varied, what was held constant, and what was never recorded.

Varied

nothing varied

Held constant

O₂ 20.0 % · measured
Pressure 101.3 kPa · nominal (stated, not measured)

Not recorded

Flow not reported in source

Condition axes: what varied and what was held constant
Axis	State	Range	Basis	Recorded
O₂	held constant	20.0 %	measured	2/2
Pressure	held constant	101.3 kPa	nominal (stated, not measured)	2/2
Flow	not recorded	not reported in source	not recorded	0/2

Placeable: 2 of 2 record O₂ and can be placed (the engine can compute a distance); 2 also record pressure and appear on the charts.
Gravity: Lunar (0.165 g) (2)
Fuel classes: Solid · thin (1) · Solid · unclassified (1)
Flow regime: natural convection (2)
Materials (2): SIBAL fabric 5 × 30 cm, downward (1) · PMMA rod 4 mm, upward (1)
Outcomes: not recorded (2)
Measured quantities: flame-base spread (1 g: 1.5) [mm/s] (1) · flame-tip spread (1 g: 2.8) [mm/s] (1) · tip spread (1 g: 0.40) [cm/s] (1)
Data-quality flags: approximate × 2: The source gives an approximate value or a range; the first value is used.
nominal-value × 2: A value stated in a document, not measured in this run.

Where the runs sit: O₂ × pressure, zoomed to the data

2 of 2 runs record both ambient O₂ and pressure and are plotted.

Source: the normalized O₂ and pressure of each run in the run table below (NASA PSI run tables or the cited paper); the original cell and any conversion are in each run’s provenance. Reference atmospheres are MARGIN’s presets. Not a hazard map.

Published records

Values transcribed from the paper (published, not a PSI table row), with the source locator and verification state of each record.

LUCI: 2 records.

LUCI: 2 records. Each value cell shows the normalized value and, beneath it, the original cell as it appears in the source.
