The Engineering Test Satellite 9 (ETS-9) is a JAXA project aimed to develop an advanced satellite bus, or common model, for various high-throughput satellites (HTS) for communications. The new satellite bus by Mitsubishi Electric will focus specifically on advanced communication needs: - Up to 25kW of power to support HTS communications - Light mass, all-electric bus system achieved with 6kW high-power Hall thrusters (Japan-made). - High-power Hall thrusters significantly shorten delivery of orbiting satellite compared to other manufacturer’s 4.5kW-class electric-propulsion bus systems - The first Japanese geostationary satellite equipped with GPS receivers (Japan-made) for laborsaving autonomous orbital transfer and orbital maneuvering.
Geostationary Transfer OrbitQZSS (Quasi Zenith Satellite System) is a Japanese satellite navigation system operating from inclined, elliptical geosynchronous orbits to achieve optimal high-elevation visibility in urban canyons and mountainous areas. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation in inclined, elliptical geosynchronous orbits.
Geosynchronous Transfer OrbitNote: Name of payload is provisional. Fourth launch of an ultimately 5 reconnaissance satellites for the South Korean Defense Acquisition Program Administration (DAPA), with 1 synthetic aperture radar (SAR) satellite on this launch. They will be launched to low Earth orbit between 600 and 700 km by 2025, enabling South Korea’s military to observe the nuclear-armed neighbor’s key military facilities every two hours with 30-50 centimeters resolution imagery, according to a 2019 report produced by the Korea Institute of S&T Evaluation and Planning. The project is lead by the Korean Agency for Defense Development (ADD) and Korea Aerospace Research Institute (KARI), with input from Korea Aerospace Industries (KAI), Hanwha Systems and Thales Alenia Space.

Low Earth OrbitSTP-S30 is a complex mission that will deliver research experiments and technology demonstrations to orbit for the DoD and contribute to future space systems development. The projected primary payload, DISKSat, will demonstrate sustained very low earth orbit (VLEO) flight and test a unique, 1-meter diameter, disk-shaped satellite bus that is designed to increase on-orbit persistence.
Low Earth OrbitRAISE-4 (RApid Innovative payload demonstration Satellite-4) is a satellite for on-orbit demonstrations of 15 demonstration components and equipment selected by public solicitation. The satellite will be operated in response to requests from the demonstration theme proposers, and will provide experimental data of the demonstration devices and environmental data during the experiments. 10 of the demonstrations are re-flight of those planned for RAISE-3, which failed to reach orbit in October 2022.
