Lab Closure Notice
Genesis Lab will be closed for air handler replacement which is scheduled for mid-December through mid-February. This schedule is approximate, and it is an incentive to submit requests early!
Genesis Bulk Metallic Glass Characterization Begins
A bulk metallic glass flown on Genesis has been re-imaged in May 2019 and is available to be requested. Bulk metallic glasses exhibit properties advantageous for solar wind collection, especially for retaining noble gases [Figure 1].
This piece has an observable impact crater (~90-100 µm diameter). The material is the unused portion of a returned sample, consisting of a mixture of Zr, Nb, Cu, Ni and Al which underwent some surface mapping of contaminants [Figure 2].
Other pieces of the metallic glass, with more complicated and uncertain handling histories,
are available now for practice subdivision and handling.
