  The galactic propagation of cosmic ray strangelets is described and the
resulting flux is calculated for a wide range of parameters as a prerequisite
for strangelet searches in lunar soil and with an Earth orbiting magnetic
spectrometer, AMS-02. While the inherent uncertainties are large, flux
predictions at a measurable level are obtained for reasonable choices of
parameters if strange quark matter is absolutely stable. This allows a direct
test of the strange matter hypothesis.
