JAXA adds a reserve period to the H3 Flight 9 QZS-7 plan

Today’s clearest public update is a schedule adjustment from JAXA. The agency published a revised notice for MICHIBIKI No. 7, the Quasi-Zenith Satellite System spacecraft QZS-7, on H3 Flight 9 and said the plan now includes a reserved launch period. This is not a newly announced mission; it is a timetable refinement on a flight already on the board.

The story so far

  1. July 10: This became the lead after current public reporting made it the strongest fresh story.
