Launch: December 15, 2017 10:35 AM EST


  • TSIS launched on a SpaceX SpX-13, Falcon 9 in the SpaceX Dragon trunk, externally on an Express Pallet Adapter (ExPA).
  • TSIS operates from an Expedite the Processing of Experiments to Space Station (EXPRESS) Logistics Carrier (ELC-3) nominally for 5 years (2 year extended mission possible).
  • The TSIS Thermal Pointing System (TPS) is deployed above the ELC after installation in order to provide sufficient solar visibility to track the sun each orbit with it’s two axis gimbal.
  • After a minimum 5 years on-orbit operations, the TPS will be re-stowed into its launch envelope by command and can be disposed.
