NASA recently concluded the final mission of its Spacecraft Fire Safety Experiment, or Saffire, putting a blazing end to an eight-year series of investigations that provided insights into fire\u2019s behavior in space. <\/p>\n
The final experiment, Saffire-VI, launched to the International Space Station in August 2023 and concluded its mission on Jan. 9, when the Northrop Grumman Cygnus spacecraft it was flying on safely burned up during planned re-entry into Earth\u2019s atmosphere.<\/p>\n
Dr. David Urban, principal investigator, and Dr. Gary Ruff, project manager at NASA\u2019s Glenn Research Center in Cleveland, have led the Saffire project from Northeast Ohio since its initial spark in 2016. Throughout the experiment series, researchers gathered data NASA will use to enhance mission safety and inform future spacecraft and spacesuit designs.<\/p>\n
\u201cHow big a fire does it take for things to get bad for a crew?\u201d Urban said. \u201cThis kind of work is done for every other inhabited structure here on Earth \u2013 buildings, planes, trains, automobiles, mines, submarines, ships \u2013 but we hadn\u2019t done this research for spacecraft until Saffire.\u201d<\/p>\n<\/p>\n
Like previous Saffire experiments, Saffire-VI took place inside a unit on an uninhabited Cygnus spacecraft that had already departed from the space station, ensuring the safety of the orbiting laboratory and a more representative flight environment. However, this final iteration of the experiment was unique because of the higher oxygen concentration and lower pressure generated in the test unit to simulate the conditions within crewed spacecraft.<\/p>\n
