# Population Mars — solar regolith paving: experiment record

One record per run. Blank fields are not results. Keep planned values and measured values in separate columns.

## Run
- Experiment ID (matrix row, e.g. 03-filler-07):
- Status: PLANNED / BUILDING / TESTING / COMPLETE / FAILED-LEARNED
- Date, site, operator:
- Question / hypothesis, and the confirm / kill threshold set before the run:

## Conditions
- Sun: DNI (W/m²) or pyranometer reading, time of day, cloud/haze, wind:
- Atmosphere: air / argon tent / vacuum (pressure):
- Optics: lens or dish ID, aperture (iris setting, mm), focal offset, spot diameter:
- Head motion: X/Y/Z path, travel speed (mm/min) or dwell (s):

## Bed and feed
- Feedstock and batch: Columbia River basalt / LMS-1 / LHS-1 / MGS-1 / other:
- Bed type: FINE (< 1 mm) / COARSE (chip size range, mm) / mixed (describe):
- Bed depth, tamping / compaction, moisture or drying history:
- Preheat: none / temperature (°C), duration, method:
- Filler: fraction (wt % of placed mass), filler temperature at entry (°C), metering rate:
- Stirring / raking: tool, strokes, timing:

## Thermal control
- Hood: ON / OFF; hood position and material; afterheat flux if used:
- Blink-and-read settings: iris closed time (ms), interval, pyrometer sample rate:

## Measurements
- Pyrometer (two-colour) trace: file, emissivity assumptions, calibration:
- LWIR camera: file, calibration range; cooling rate through 1,100 → 900 °C (°C/s or °C/min):
- RGB video: file, timestamps of pool formation, foaming, lockup:
- Rake load cell: force (N) vs time, with temperature and estimated solids fraction at each point:
- Lockup point (filler fraction and temperature where the pool stopped flowing):
- Mass before / after (degassing loss):

## Coupon results
- Sample IDs and sectioning plan:
- Melt depth (mm) from sectioning:
- Porosity / bubble count:
- Glass vs crystalline (visual, hardness, XRD if sent out):
- Crack census (count, length, whether cracks follow scored joints):
- 3-point bend (MPa), tumble abrasion (mass loss), LN₂ ↔ kiln cycles survived:
- Blade: coating state, wear, sticking:

## Outcome
- Confirm / kill / inconclusive, against the threshold stated above:
- Repeats and spread:
- Failures and aborted runs (keep them):
- What the data support and what remains unknown:
- Next run and why:
