- The GOES-11 is a real National Oceanic and Atmospheric Administration (NOAA) satellite. GOES stands for Geostationary Operational Environmental Satellite. It was launched into space in 2000, and remained operational for the west coast of the United States until it was decommissioned and replaced by GOES-15 on December 6, 2011, a year after this episode aired. GOES-11 was put into place to replace the older GOES-10, which was 6 years past its recommended use time. GOES-11 was also over 1 year beyond its use time by the time it was launched, as it lacked the instruments put on GOES-12, which was launched prior to it.
