Overview
- JAXA launched an H3 from Tanegashima and the Michibiki 7 satellite reached its planned orbit about 30 minutes after liftoff.
- The flight was the H3's ninth launch and marks another recovery for the vehicle after two earlier failures and a return-to-flight success in June.
- Michibiki 7 joins Japan's Quasi-Zenith Satellite System to expand a GPS-compatible network that aims to deliver centimeter-level positioning and emergency broadcasts across the Asia‑Oceania region.
- The satellite carries the U.S. Situational Awareness Camera Hosted Instrument (SACHI), developed by MIT Lincoln Laboratory for the U.S. Space Force to observe satellite behavior in GEO and test sensitive data‑sharing methods with Japan.
- The outcome strengthens confidence in the H3 for future missions and advances Japan's aim for a larger, more autonomous regional navigation system while deepening U.S.–Japan cooperation on space situational awareness.
