In the high bay of Kennedy Space Center's Space Station Processing Facility, Chris Hardcastle, right, of Stinger-Ghaffarian Technologies performs a sharp edge inspection of the integrated Total and Spectral Solar Irradiance Sensor-1 (TSIS-1) payload and the EXPRESS Pallet Adapter. Hardcastle is joined by Norm Perish, left, a TSIS-1 payload team member from the Laboratory for Atmospheric and Space Physics, a Research Institute at the University of Colorado (Boulder). TSIS-1 is designed to measure the Sun's energy input into Earth by seeing how it is distributed across different wavelengths of light. These measurements help scientists establish Earth's total energy and how our planet's atmosphere responds to changes in the Sun's energy output. TSIS-1 will launch on SpaceX's 13th commercial resupply mission to the International Space Station
