Defying Gravity Libido Inhibitor “Halo” Lot

These libido inhibitors, or “HALOs” (Hormone Activated Libido Oppressors) were worn by Antares’s crew behind their ear to curb their libidos during the Antares mission. They are seen throughout the series, but are formally introduced in “Law of Natural Selection” to the astronaut candidates during training in a flashback sequence. Production noted these items as being screen used.
