We present new Hubble Space Telescope (HST) abundance observations of the neutron-capture elements Ge, Zr, Os and Pt in a group of 11 Galactic halo stars, including the well studied r-process rich CS 22892-052 and the r-process poor, bright giant HD 122563. Abundance comparisons indicate that the third r-process peak elements Pt and Os seem to be correlated with Eu (obtained with ground-based observations) in these metal-poor halo stars, suggesting a common origin or site for these three n-capture elements.
