COLUMBIA, MD (USRA PR) — NASA has been conducting a series of space fire experiments called Spacecraft Fire Safety (Saffire) Experiments that investigate how fires grow and spread in space, especially aboard future spacecraft bound for Moon and Mars. Recently, another set of experiments were conducted when Saffire IV lit longer and stronger flames inside Northrop Grumman’s Cygnus Cargo spacecraft.

CLEVELAND (NASA PR) — Engineers at NASA’s Glenn Research Center in Cleveland, Ohio and Orbital ATK in Dulles, Virginia successfully conducted the first remote Spacecraft Fire Experiment, or Saffire I, carried inside an Orbital ATK Cygnus cargo vehicle that departed the International Space Station on Tuesday, June 14.  The experiment’s purpose is to learn how a fire might behave in a spacecraft after leaving Earth’s atmosphere. Understanding how fire spreads in a microgravity environment is critical to the safety of astronauts who live and work in space as NASA prepares for long duration missions on the journey to Mars.
