Abstract
Heating elements and temperature sensing devices are positioned in diametrically opposed pairs along a tubular boom extending outwardly from a spacecraft. As temperature differentials are detected across the diameter of the boom, current is selectively applied to the heating element on the cooler side of the boom to equalize the temperature and prevent boom distortion. In another application, current may be selectively applied to a heating element to cause bending of the boom to achieve a desired positioning of the tip portion of the boom.
