Upcoming Spaceflights
H3 | Michibiki 5 (QZS-5)
Mitsubishi Heavy Industries | JPNTanegashima Space Center, Japan
TBD January, 2024
Status: To Be Determined
Mission:
QZSS (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.

H3 | Lunar Polar Exploration Mission (LUPEX)
Mitsubishi Heavy Industries | JPNTanegashima Space Center, Japan
TBD January, 2025
Status: To Be Determined
Mission:
The Lunar Polar Exploration mission (LUPEX) is a robotic lunar mission jointly developed by the Indian Space Research Organisation (ISRO) and Japan Aerospace Exploration Agency (JAXA), deploying a lunar rover and lander to explore the south pole region of the Moon. JAXA will provide the under-development H3 launch vehicle and the rover, while ISRO would be responsible for the lander.
Lunar OrbitH3 | ETS-9
Mitsubishi Heavy Industries | JPNTanegashima Space Center, Japan
TBD April, 2025
Status: To Be Determined
Mission:
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.
