The Total and Spectral Solar Irradiance Sensor 2 (TSIS-2) is a satellite designed by NASA to measure the Sun's energy input to Earth. TSIS-2 comprises two instruments, the Total Irradiance Monitor (TIM), and the spectral Irradiance Monitor (SIM). TIM measures total brightness and SIM measures spectral irradiance over a wavelength range that includes 96% of the energy in the solar spectrum. Both instruments are similar to those used for the TSIS-1 mission onboard the International Space Station.
Sun-Synchronous OrbitPlato, for PLAnetary Transits and Oscillations of stars, is a European Space Agency (ESA) mission with 26 cameras to study terrestrial exoplanets in orbits up to the habitable zone of Sun-like stars. Its goal is to measure the sizes of exoplanets and discover exomoons and rings around them, as well as characterise planets' host stars by studying tiny light variations in the starlight it receives.
