A new instrument that will monitor our planet’s biggest power source, the Sun, arrived at NASA’s Kennedy Space Center in Florida. It has a targeted November 2017 launch on a SpaceX Falcon 9 rocket to the International Space Station. The Total Solar and Spectral Irradiance Sensor (TSIS-1) instrument was built by the University of Colorado’s Laboratory for Atmospheric and Space Physics (LASP) for NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
