On the cover: Philip Stauffer of Los Alamos National Laboratory tests the fit of an inflatable packer as part of the Brine Availability Test in Salt (BATS) experiment. This thermal test is being performed 650 m below the surface in the WIPP facility through funding provided by the U.S. Department of Energy.
