Summarize

What NASA found

  1. BASS and BASS-II · analogous evidence · Reported observation

    “Both blowoff and quenching limits were obtained at several oxygen concentrations.”

    Why it is relevant: The finding addresses oxygen; this topic is requested or triggered by the selected conditions.

    Limitation: Publication-level evidence: no explicit test-row link is curated for this finding. Numeric condition coverage is unknown.

  2. LUCI · analogous evidence · Reported observation

    “These are the first-ever, extended-duration (greater than 25 seconds) combustion tests performed in simulated Lunar gravity.”

    Why it is relevant: The finding addresses partial-gravity; this topic is requested or triggered by the selected conditions.

    Limitation: Publication-level evidence: no explicit test-row link is curated for this finding. Numeric condition coverage is unknown.

  3. Martian-gravity drop tests · analogous evidence · Reported observation

    “Previous testing at microgravity and Lunar gravity indicated that some materials burned to lower oxygen concentrations in low gravity than in normal gravity, although the low g extinction limit criteria are not the same as 1g due to time constraints in drop testing.”

    Why it is relevant: The finding addresses oxygen; this topic is requested or triggered by the selected conditions.

    Limitation: Publication-level evidence: no explicit test-row link is curated for this finding. Numeric condition coverage is unknown.

Rank

Which evidence matters most?

Two rankings, kept separate. These are MicroFire ranking heuristics, not NASA safety scores. The best BASS-II row scores only 25 / 100: those tests ran in orbit at sea-level pressure, far from this scenario. That low number is part of the answer.

Interpret

What does this mean for the mission question?

NASA observed
“Both blowoff and quenching limits were obtained at several oxygen concentrations.”
Why it matters here
The finding addresses oxygen; this topic is requested or triggered by the selected conditions. PMMA appears in the quote, material-specific source, or curated supporting records.
MicroFire interpretation
The reported boundaries make oxygen and airflow relevant to the research question. A rod result does not establish limits for a panel, fabric or different habitat.
Limitation
Publication-level evidence: no explicit test-row link is curated for this finding. Numeric condition coverage is unknown.

AI-powered

Where AI helps

The model never decides what NASA observed. MicroFire retrieves the evidence first and verifies generated factual claims afterward.

  1. QuestionWhat happens to a PMMA flame when airflow changes in microgravity?
  2. NASA evidence retrieved firstB16 · B20 · B19
  3. AI synthesisAll three BASS-II runs used 2-cm, 100-µm-thick PMMA in opposed flow at about 16.4–16.5% O2 aboard the ISS. Outcomes differed: B16 quenched, B20 burned the entire sample, and B19 blew off; the reported fan “pot” settings were different across runs.

    • ✓ Every citation exists in the retrieved evidence
    • ✓ Every number appears in the cited NASA records
    • ✓ Units match the cited evidence
    • ✓ No microgravity result told as Moon or Mars
    • ✓ No causal or safety claim the evidence does not make
    • ✓ No past outcome turned into a prediction
  5. VerifiedVerified example: a saved answer re-checked by the current checker on every build. Not a live request. Deterministic checks do not prove every sentence is scientifically entailed.

Matched-condition research question

PMMA, 34 % O₂, 56.5 kPa, 20 cm/s airflow, lunar gravity. The closest record, Saffire VI sample VI-3, differs in gravity, oxygen.

Computed from the missing conditions. A research question, not a NASA-endorsed experiment plan.

MicroFire says no

“What is the probability that PMMA ignites in a lunar habitat at 34% oxygen?”

No valid probability can be estimated from the current evidence.

Why
MicroFire Atlas reports NASA evidence; these records do not establish mission safety, fire probability, predictions or isolated causal proof.
Closest evidence
LUCI PMMA rod (simulated lunar gravity). Simulated lunar gravity: a spinning rocket, about 2.5 minutes, with Coriolis force; oxygen fell during the burn.
Main mismatches
20 % O₂, not 34 %

What NASA directly tested
No NASA test in this atlas matches every condition.Each condition on its own: material in 30 records, gravity in 2 records, oxygen never, pressure in 3 records, airflow in 40 records.
Closest evidence
Saffire VI sample VI-3. NASA recorded: Grew continuously until the flow was reduced.Differs in: oxygen, pressure, gravity.
Most relevant finding
“Both blowoff and quenching limits were obtained at several oxygen concentrations.”BASS and BASS-II, analogous evidence.
What AI contributed
Synthesized the retrieved NASA evidence into plain language; 2 of 2 claims passed every deterministic check.Saved, verified example re-checked on every build, not a live request. The AI never decided what NASA observed.
Main uncertainty
No test record is within ±1.5 points of 34 % oxygen.
What cannot yet be claimed
Any outcome or probability for this condition.The AI Model Lab blocks a prediction here (gravity, pressure, oxygen, airflow outside its evidence). MicroFire Atlas reports NASA evidence; these records do not establish mission safety, fire probability, predictions or isolated causal proof.
