NASA Space Apps Challenge 2026 · Flame in Freefall
AndroFlame
Decoding Fire Beyond Gravity
Objective
AndroFlame is an open-science intelligence and data-synthesis engine engineered to decode the complex, non-intuitive physics of fire in microgravity. Without buoyant convection, flames do not rise—they burn as spherical, slow-diffusing balls governed by molecular transport, radiative heat loss, and delicate ventilation currents.
Our core mission is to bridge 50 years of NASA microgravity combustion research with future human spaceflight safety. By ingesting, harmonizing, and structuring published datasets from NASA's Physical Sciences Informatics (PSI) repository, AndroFlame turns isolated test runs into actionable intelligence for deep-space habitat architects, fire-safety researchers, and mission planning engineers.
- Synthesize: 24 flight & ground investigations with 1,980+ experimental table rows.
- Benchmark: Test habitat atmospheres (Lunar, Mars, ISS) against documented flight data.
- Ground AI: Strictly evidence-backed assistant with zero hallucination and verbatim citations.
Scope and Target Audience
Empirical & Literature Scope
The platform encompasses all combustion science investigations cataloged in NASA's Physical Sciences Informatics (PSI) repository, including:
- 24 Microgravity Investigations: Across droplet combustion (FLEX, FLEX-2), solid flame spread (BASS, BASS-II), gaseous flames (ACME), smoke detection (SAME, DAFT), and soot dynamics (SPICE).
- 1,980+ Verified Test Runs: Verbatim reporting of oxygen (0% to 40% O₂), chamber pressures (vacuum to 300+ kPa), airflow velocities, and fuel dimensions.
- Flight Hardware: Combustion Integrated Rack (CIR), Microgravity Science Glovebox (MSG), and space shuttle middeck rigs.
- Extended Roadmap: Historical and complementary programs including Saffire on Northrop Grumman Cygnus vehicles and ground drop towers.
Target Audience
AndroFlame serves multiple multidisciplinary stakeholders across space science and mission design:
- Spacecraft Fire Safety Engineers: Designing habitat materials, fire detection thresholds, and active suppression systems for Artemis and Mars missions.
- Combustion Researchers: Investigating fundamental transport phenomena, chemical kinetics, cool flames, and extinction limits in buoyancy-free environments.
- Habitat Architects & Mission Planners: Benchmarking environmental conditions (e.g. 34% O₂ at 56 kPa for lunar EVA prep) against empirical flammability boundaries.
- Students & Academics: Exploring open-access NASA flight data with interactive visualization tools and traceable citations.
Limitation
Scientific & Methodological Boundaries: AndroFlame is an independent research discovery and data-synthesis instrument created for the 2026 NASA Space Apps Challenge. Users must keep the following constraints in mind:
- Not a Certified Safety Calculator: AndroFlame is not an operational fire-risk calculator, certified material qualification system, or life-safety flight software. It does not replace NASA-STD-6001 materials testing or official flight qualification protocols.
- Data Absence is Not Non-Flammability: An absence of documented experimental rows at a specific pressure or oxygen level in the PSI archive indicates a data gap—it is not proof that a material will not ignite or that no hazard exists.
- Scale & Geometry Effects: Small-scale glovebox/chamber samples (droplets, narrow fuel cards) do not capture full-scale turbulent vehicle fire dynamics or complex ventilation duct geometries without coupled computational fluid dynamics (CFD).
- Zero Hallucination Policy: The AI synthesis answers cite only verbatim PSI records and official publications [S#]. When a topic is not addressed in NASA records, the system explicitly abstains rather than inventing speculative extrapolations.
- Verify AI Results Before Use: Answers from the AI chatbot and the Ask feature are generated from model confidence, not certainty, so no AI output should be trusted 100%. Check every result precisely against the cited sources [S#] before using it in research, design, or safety decisions.
