Solid rocket boosters were previously deemed unsafe for human space flight because once they're lit, they don't stop boosting until the fuel is gone. Liquid-fueled rockets can be shut off.
Definition of conductive. : having conductivity : relating to conduction (as of electricity)
Electrical conductivity is the measured amount of current generation created on a metal targetâs surface. More simply, it is how easily an electrical current can flow through a metal. While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring since the days of the telegraph.
