Spacelab D2 (26 April - 6 May 1993) conducted life sciences experiments in four general areas: biological techniques (electrofusion of cells), biology (cell functions, reaction to gravity, development processes, and behavioral physiology), human physiology (heart-lung system, lung functions, endocrinology, and metabolism), and radiation physics. Of the five double-racks on board Spacelab D2, one was Germany's Bilabor for cell, botany, and zoological experiments, and one was ESA's Anthrorack. As with Spacelab D1, Spacelab D2 was controlled by a payload team at GSOC (References 9-11).
