NASA Space Apps 2026 · Flame in Freefall
Which NASA microgravity fire experiments speak to your spacecraft atmosphere?
Moon and Mars vehicles plan to run at lower pressure and higher oxygen than the ISS, which makes materials burn more readily. Pick a cabin atmosphere: Flame in Freefall ranks NASA's flight investigations by how directly their data covers it, states what the flight tests measured there (each figure linked to the source row), estimates droplet-flame outcomes with a validated model, and says plainly what the data cannot tell you.
1 · Choose a cabin atmosphere
Values quoted or derived from NASA/TM-2008-215260, or your own.
3 · Ranked investigations
Evidence relevance to this atmosphere (not a risk score). Hover the bar for each weighted component.

4 · What the flight data says here
Measured = computed from flight-test rows · Model estimate = validated FLEX model · Coverage gap = not covered. Click a test ID to see its source row.
