Overview
- JAXA said on Monday that the H3 No.6 launch scheduled for June 10 was postponed because forecasts showed bad weather and a risk of lightning around the Tanegashima launch site.
- No.6 is a simplified '3-0' test vehicle that will fly using only the main engines to validate design and procedures after the H3 No.8 failure in December.
- JAXA has repaired and strengthened the satellite-mounted section on No.6, which investigators identified as a likely direct factor in the December failure.
- Some media reported a possible June 12 window for the launch, but JAXA has not confirmed a new date and will reconvene to reassess launchability starting June 9.
- A successful No.6 flight would shape the H3 program's recovery and Japan's plans for lower-cost domestic launch capacity, while further delays could push back commercial and test schedules.
