NASA sets a fire in space

What’s a fire like in space?  Yesterday, NASA found out by setting the largest intentional fire in space and then observing, The Washington Post reports. The fire—set by touching a hot wire to a cotton and fiberglass card—took 8 minutes to burn the material inside of the insulated trash-filled vehicle. Scientists say that is much longer than it would have taken on Earth. In order to prepare for the longer manned missions to Mars, NASA scientists say it is important to understand how big a fire can get, how rapidly it grows, and how quickly the fire changes the conditions inside the vehicle. NASA is still collecting and analyzing data from the fire to decide where to go from here as far as fire safety on spacecraft.
