Fire-safety experiment among science gear launching to International Space Station this weekend

A Cygnus cargo ship launching toward the International Space Station (ISS) this weekend will carry an experiment designed to improve fire safety on moon and Mars missions.

Called SoFIE (Solid Fuel Ignition and Extinction), the experiment is the latest in a series of in-orbit investigations that look at how fire behaves in microgravity. SoFIE is part of a larger haul of science, supplies and hardware flying on Northrop Grumman’s Cygnus NG-17 resupply mission, which is scheduled to launch at 12:39 p.m. EST (1739 GMT) on Saturday (Feb. 19).
