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 OrbitThor 8 is a multi-purpose communications satellite for Space Norway. The satellite will both replace older satellites being phased out in the coming years and provide increased capacity and service offerings that offers capacity for both data services and broadcasting, such as high power direct-to-home (DTH) television services, from the 1° West orbital position. It carries two dedicated payloads for broadcasting in Europe and the Nordics, as well as payloads for data services to commercial and governmental customers. With a launch mass of 4 metric tons, the satellite will be built on Thales Alenia Space’s Spacebus-4000B2 platform and will operate in the Ka and Ku frequency bands.
