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 OrbitThe Skynet 6A gap-filler military communications satellite built by Airbus Defence and Space to cover the gap between the Britisch Skynet-5 network and its successor. Skynet 6A was solesourced from Airbus Defence and Space in 2017, but was not fully funded until July 2020. Aibus will build the Skynet-6A satellite in the United Kingdom and arrange a 2025 launch. RAL Space, a U.K. national laboratory, will test the all-electric satellite at its facility in Harwell. Skynet-6A, based on the Eurostar-Neo platform, is expected to provide communications services for the British military until at least 2040.
