Fire safety is a crucial component of space living. As we partner with industry and international space agencies to develop deep space habitation capabilities, we are leveraging every opportunity to validate important habitation-related systems and operations in low-Earth orbit. The second Spacecraft Fire Safety experiment, or Saffire-II, is a fire experiment with nine material swatches that will be ignited in a cargo ship as it orbits Earth. Saffire-II is the second in a series of three fire safety experiments, and builds on the data captured during Saffire-I with an expanded test portfolio of new materials.
Saffire-II launched on OA-5 in October 2016. The nine samples in the experiment kit aboard the Cygnus cargo vehicle include a cotton-fiberglass blend, Nomex, and the same acrylic glass that is used for spacecraft windows. After the spacecraft departs the station, and before its destructive reentry to Earth, mission controllers on the ground will remotely ignite the samples.
