Cape Canaveral Air Force Station in Florida, SpaceX launched a new sensor to the International Space Station named 'TSIS-1'
Its mission: to measure the dimming of the sun. As the sunspot cycle plunges toward its 11-year minimum, NASA satellites are tracking a slight but significant decline in total solar irradiance (TSI). TSIS-1 will monitor this dimming with better precision than previous satellites as Solar Minimum approaches in the years ahead.
