NASA instrument key to understanding solar powered planet arrives at Kennedy Space Center
04 August 2017
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.
Scientists will use TSIS-1 to study the Sun's energy input to Earth. Specifically, it will measure both the total amount of light that falls on Earth, known as the total solar irradiance, and how that light is distributed among ultraviolet, visible and infrared wavelengths, called solar spectral irradiance.
