Saffire-VI: one-sided PMMA burn

Real NASA footage, measured frame by frame with a documented computer-vision pipeline. Switch between the raw footage, the computed flame outline, and the measurements.

The computer traces bright and blue flame pixels frame by frame. Not yet validated against hand-annotated real frames.

Saffire-VI, inside Northrop Grumman's Cygnus at the end of NG-19

Material: PMMA, burning on one side (from NASA's file name).

Oxygen, pressure and airflow are not given. The file name says “20x”, which NASA's text does not explain, so times are shown as video time.

“NASA ignited the final set of space fire experiments for Saffire-VI inside Northrop Grumman’s Cygnus cargo spacecraft at the end of the NG-19 resupply mission to the International Space Station. Saffire, or Spacecraft Fire Safety Experiment, was a series of six investigations that provided insights into how fires grow and spread in space. This research is especially important as it will inform future spacecraft desig…”
