Congress forcing a compromise(d) Space Shuttle design on NASA. Among other things, the space shuttle was the first human space vehicle to use solid rocket boosters. 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 ability of a material to carry the flow of an electric current (a flow of electrons).Imagine that you attach the two ends of a battery to a bar of iron and a galvanometer.nother way of describing the conductivity of a material is through resistance. Resistance can be defined as the extent to which a material prevents the flow of electricity. Silver, aluminum, iron and other metals have a low resistance (and a high conductivity).
