2 of 7 Saffire burns ran inside the Moon Base atmosphere range

The challenge expects lunar habitats at 30% oxygen or more and 10.2 psi or less. Only VI-3 and VI-2 sit inside it, and nothing in the set was burned above 31% oxygen.

Where the data stops

Limits a study plan has to work around. Each is stated by a source or counted from the files.

Partial gravity0

lunar- or Mars-gravity combustion datasets in NASA’s PSI repository. Every case here ran in microgravity.

Challenge statement
Oxygen ceiling31%

is the highest oxygen level among the 7 atmosphere cases. Nothing in this set was burned above it.

Flow direction1

unresolved conflict: the 2026 table says opposed flow, the 2024 table says concurrent. Flow is left out of every comparison.

SAME-R obscuration readings are stored as 0 V. The workbook does not establish the channel state on that flight.
