I will go back and look at the slides when they make them available. They had that information in there. They are also slated to put more GOES satellites in orbit. The next one will be going up in 2018.
GOES-13 was previously out of service, from 22 May to 9 June 2013, due to technical difficulties following a micrometeoroid collision. It is designated GOES-East and is currently located at 75°W. It provides most of the U.S. weather information.
