More: fire-safety equipment, Earth, spacesuits and rockets

This page shows which PSI combustion investigations relate to fire detection, suppression and prevention, what their PSI records and NASA's challenge statement say about uses on Earth, and what lies outside PSI (spacesuits, rockets). Every sentence in quotation marks is copied word for word, with its source named.

Fire-safety equipment & Earth

“NASA’s spacecraft fire safety work is focused on prevention, detection, and suppression.” (NASA Space Apps 2026 challenge statement, challenge page). Below, one card per leg: only quotes, each from a PSI record field or from the challenge statement.

Detection: smoke and aerosol measurements

“Fire detection was tested in microgravity through the Smoke and Aerosol Measurement Experiment studies (SAME and SAME-R).” (NASA Space Apps 2026 challenge statement)
“The SAME experiment will provide technology for an advanced fire detector for future spacecraft” (PSI record PSI-102, field researchImpacts)
“the results from SAME-R can lead to technology for an advanced fire detector for future spacecraft” (PSI record PSI-101, field researchImpacts)
“NASA technology has similarly led to improvements in terrestrial smoke detection” (NASA Space Apps 2026 challenge statement, part of a sentence)

Suppression: diluting the atmosphere

“Suppression was studied in the Flame Extinguishment Experiment (FLEX) through dilution of the chamber atmosphere with carbon dioxide and helium, both of which suppress fire.” (NASA Space Apps 2026 challenge statement)
“measure the effectiveness of various gaseous fire suppressants such as CO2, He, and SF6” (PSI record PSI-69, field objective)
“Fine-water-mist extinguishers developed for use on the ISS have practical applications here on Earth” (NASA Space Apps 2026 challenge statement, part of a sentence)

Prevention: material flammability and material selection

“Prevention is achieved by controlling ignition sources and through material selection, which depends on understanding flammability limits.” (NASA Space Apps 2026 challenge statement)
“Flammability studies focus on solid materials such as fabrics and plastics, as studied in the Burning and Suppression of Solids (BASS and BASS-II) and Spacecraft Fire Safety Demonstration (Saffire-I, -II, and -III) investigations.” (NASA Space Apps 2026 challenge statement)
“Current NASA spacecraft materials selection is based on a standard test method (NASA–STD–6001 Test 1) that segregates material based on 1-g behavior without consideration of low gravity effects.” (PSI record PSI-26, field researchImpacts)
“Study the ignition, flame growth, flame spread, and extinction limits for solid fuels burning in low-velocity forced flows in microgravity.” (PSI record PSI-25, field objective)
“investigate the low-g flammability limits compared to those obtained in NASA’s normal gravity material flammability screening test.” (PSI record PSI-98, field objective)

On Earth, as stated in the PSI record

NASA's challenge says: “Your dashboard could also address potential applications of the PSI data to fire safety on Earth.” Below are only the investigations' own sentences from the researchImpacts field of their PSI records that speak of use on Earth (21 sentences from 16 investigations). They are what the records state, not claims checked by PYRION. Which sentences are shown is a PYRION convention: those that say “on Earth”, “for Earth”, “to Earth”, “terrestrial”, “Earth benefits” or “Earth environments”.

Spacesuit atmosphere: outside PSI

From NASA's challenge: “To enable flexibility, spacesuits are filled with 100% oxygen to only 4.3 psi (pounds per square inch), where the Earth's pressure at sea level is 14.7 psi.”

Oxygen
100 %
Total pressure
4.3 psi
Oxygen partial pressure
29.65 kPa (4.3 psia)
Oxygen partial pressure = 100 % x 29.65 kPa (4.3 psia) = 29.65 kPa (4.3 psia). computed by code (PYRION engine, unit table of validation/run_all.py (1 psia = 6.894757 kPa, 1 atm = 101.325 kPa, 1 mmHg = 0.1333224 kPa)).

Outside PSI: no PSI test at these conditions. The highest ambient oxygen of any PSI test is 40 %. This card is information, not a verdict. NASA's material test standard is NASA-STD-6001B, Flammability, Offgassing, and Compatibility Requirements and Test Procedures (approved 08-26-2011; the file is in data/raw/nasa/nasa-std-6001b/). A historical copy on standards.nasa.gov. No DOI.

Rockets and propellants: beyond PSI's scope

NASA's challenge says, in a footnote: “Fire safety involving rockets and propellants is generally beyond the scope of the research available in the PSI database. The high velocities within rocket engines render the combustion effectively independent of gravity — although a rocket's launch is of course strongly dependent on gravity.” PYRION therefore does not address rocket or propellant fire safety.
