What this site is
burnrate shows what NASA's microgravity flame tests say about a fire in a spacecraft cabin.
You choose a cabin air and the site counts the tests that ran in it. Its analyses cover flame spread and putting a flame out.
An entry to the NASA Space Apps Challenge 2026, challenge “Flame in Freefall”.
Where the data comes from
Every record, table and file comes from NASA's Physical Sciences Informatics (PSI) repository, psi.nasa.gov (opens in a new tab).
Each investigation keeps its PSI ID, for example PSI-69. The ID is shown beside every number, so you can find the source record.
If the live data service does not answer, the site shows a saved copy and says so at the top of the page.
How the numbers are obtained
Click a number in an analysis to see its test, its PSI file and how it was obtained. Each way has a badge:
- measured from videoMeasured by software that follows the flame in NASA's video.
- measured by handMeasured by a person, by hand, from NASA's images or video.
- from NASA's tableCopied from an experimental table that NASA publishes in the PSI repository.
- published by NASAA value printed in a NASA publication or record.
- read by SIRead from a NASA document by a language model (SI). Check it against the source.
- computedComputed by this analysis from NASA's numbers. Not measured.
“Example data” marks a placeholder value. “Being measured” marks a check that has not run yet. Neither is a result.
How SI was used
- A language model writes the plain-words summaries of the investigations. Each one is labelled and sits next to NASA's own words.
- The assistant answers only from the data on this site and cites the investigation behind each answer.
- The analyses and the code were written with SI assistance and reviewed by the team.
