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 OrbitJSAT-32 is a geostationary communication satellite for SKY Perfect JSAT. Operating in the Ku and Ka frequency bands, JSAT-32 will provide coverage over Japan and its surrounding seas, with newly added spot beams for mobility applications. JSAT-32 will serve as a future replacement for existing SKY Perfect JSAT satellites that provide communication and distribution services in Japan.
Geostationary Transfer 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 Orbit2nd of the National Team’s Blue Moon MK1 lunar lander test missions to validate the necessary technologies for its HLS lunar module. Some of the life support hardware will travel on this mission in preparation for the first crew Blue Moon flight. This mission will also carry NASA’s VIPER (Volatiles Investigating Polar Exploration Rover) lunar rover. VIPER is designed to explore the relatively nearby but extreme environment of the Moon in search of ice and other potential resources. This mobile robot will land at the South Pole of the Moon on a 100-day mission, in order to teach us about the origin and distribution of water on the Moon and help determine how we can harvest the Moon's resources for future human space exploration. VIPER is designed to roam the Moon using its three instruments and a 1 meter long drill to detect and analyze various lunar soil environments at a range of depths and temperatures. The rover can venture into permanently shadowed craters, some of the coldest spots in the solar system, where ice reserves have endured for billions of years. The rover was originally slated to launch on Astrobotic’s Griffin Mission One lunar lander (with the Falcon Heavy rocket), but the VIPER mission was cancelled in July 2024 due to budget cuts. After consulting with the industry to find alternative ways to deliver the rover to the lunar surface, NASA ultimately chose to launch it with Blue Origin’s 2nd Blue Moon MK1 lander mission.
Low Earth OrbitChandrayaan-4 is a planned lunar sample-return mission of Indian Space Research Organisation (ISRO) and will be the fourth mission of its Chandrayaan programme. The mission consist of five modules, namely the DM (Descender Module), AM (Ascender Module), TM (Transfer Module), RM (Re-entry Module) and PM (Propulsion Module). The planned mission life is 1 lunar day and the landing site will be near the Lunar South Pole. The first launch will lift the DM (Descender Module) and AM (Ascender Module) to orbit.
