Space Shuttle technicians prepare to re-install three fuel cells in space shuttle Discovery’s mid-body, on December 9, 2011. The fuel cells were removed and drained of all fluids in preparation for public display. The hydrogen and oxygen dewars which feed reactants to the fuel cells remain in Discovery’s mid-body and have been purged with inert gases and vented down. (NASA/Dimitri Gerondidakis)
