NASA has developed a new instrument to study the sun. The Total and Spectral Solar Irradiance Sensor (TSIS-1) became fully operational this month, after it was installed on the International Space ...

The Total and Spectral Solar Irradiance Sensor-2 would continue the mission of the first TSIS, an existing space sensor designed to measure the sun’s radiation that reaches Earth, NASA said Monday.

NASA has awarded a sole source contract to the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder for the Total and Spectral Solar Irradiance Sensor-2 (TSIS-2).

Data obtained by NASA's Total Solar Irradiance Sensor showed sun is entering a 11-year cyclic electromagnetic output low and this could continue diminishing over time.

NASA has powered on its latest instrument on the International Space Station (ISS) to detect the total amount of light energy emitted by the Sun Total and Spectral solar Irradiance Sensor (TSIS-1 ...

Measurement of the solar irradiance distribution of sun simulators The UniformSun measuring system is based on a new development by Ingenieurbüro Mencke & Tegtmeyer GmbH.

NOAA, the U.S. Air Force and NASA agreed this week to restore the Total Solar Irradiance Sensor (TSIS) to the first NPOESS (National Polar-orbiting Operational Environmental Satellite System). Set ...

The Total and Spectral Solar Irradiance Sensor, known as the TSIS-1, was designed and built at CU’s Laboratory for Atmospheric and Space Science, for NASA’s Goddard Space Flight Center in ...

Under this contract, the LASP will provide two instruments – the Total Irradiance Monitor (TIM) and the Spectral Irradiance Monitor (SIM). LASP will also provide all necessary support to ...
