Nearly 30 experiments in materials processing were conducted with nine different types of science facilities. DARA provided the TEMPUS, flying for first time on IML-2, designed to allow study of solidification of materials from liquid state in a containerless environment. Solidification phenomena are of great interest to science and also used in many industrial processes. Science teams detected for first time a phase in a nickel-niobium sample that is masked by other forces on Earth.

The Atomic Oxygen Exposure Tray (AOET) was a self-standing facility located on the Spacelab D-2 support structure and performed experiments in materials science. The AOET used the Shuttle orbiter as an exposure laboratory to obtain inside reaction rate measurements of various materials interacting with atomic oxygen in the low-Earth orbital environment. The AOET consisted of a sample array containing 124 sample plates.

STS-55

ROSAT is a German - US - UK collaboration, launched on the 1st June 1990 and still operating today. Its mission consisted of
two distinct parts: the first six months were devoted to an All-Sky Survey, the first ever to be performed with an imaging X-ray
telescope
