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.
Geostationary Transfer OrbitNeonSat-7 to 11 are part of the South Korean government's Earth observation micro-satellite constellation NeonSat (New-space Earth Observation Satellite). The NeonSat constellation is the first satellite system developed by the government using a mass-production approach for precise monitoring of the Korean Peninsula.
Sun-Synchronous OrbitSpace Machines Company (SMC)'s second Optimus Orbital Transfer Vehicle (OTV), will launch on a mission designated Space MAITRI (Mission for Australia-India’s Technology, Research and Innovation). The mission will focus on debris management and sustainability, and will significantly advance Australia’s domestic space industry by combining Australian spacecraft capabilities with India's launch expertise. After separation, Optimus will perform a series of propulsive on-orbit maneuvers to inspect a space object in close proximity. It will then spend several months on orbit examining space debris to demonstrate affordable and accessible space sustainability technologies.
