Evidence proximity, not a safety rating. This page describes what was tested and where each value comes from.
Where BASS’s runs sit in condition space, in the Atlas chart window. Other investigations’ runs in this regime are dimmed.
0 of 121 runs drawn · 121 runs without O₂ or pressure are not drawn.
As written in the PSI record:
The two main objectives for BASS are to: 1.) Begin to bridge the gap between the normal gravity NASA-STD-6001 Test#1 method, ground-based microgravity tests, and actual material flammability in microgravity. The relation between these can be investigated by observing flames burning for the longer times available in flight. Practical, realistic (thicker) fuels in typical geometries will be examined, including wake flames which have characteristics of a fire burning behind another object (for example, a fire burning in tight area which may not be easily accessible). 2.) Assess the effectiveness of an inert, gaseous extinguishing agent (similar to that used on ISS) in putting out flames over different materials, geometries, preheating, and flow.
Computed from the 121 run rows below: what varied, what was held constant, and what was never recorded.
| Axis | State | Range | Basis | Recorded |
|---|---|---|---|---|
| O₂ | not recorded | no o₂ column in the PSI table | not recorded | 0/121 |
| Pressure | not recorded | no pressure column in the PSI table | not recorded | 0/121 |
| Flow | not recorded | no flow column in the PSI table | not recorded | 0/121 |
Nothing from this investigation can be placed on an O₂ × pressure chart: 121 runs: no O₂ value recorded in the source row.
Normalized values with the original cell beneath each. Inspect a row for its conversions, flags, source and distance to your scenario. 1 non-run row in the CSV (notes or headers) were not treated as runs.
BASS: 121 runs from PSI-26_Experimental table_BASS.csv, showing the first 50.
