H3-30 — H3-30 Test Flight
| Agency | Mitsubishi Heavy Industries |
| Rocket | H3-30 |
| Payload | Test flight with dummy payload and small satellites |
| Orbit | Sun-Synchronous Orbit |
| Launch Site | Yoshinobu Launch Complex LP-2, Tanegashima Space Center, Japan |
| Time (UTC) | 00:53 |
| Status | IN FLIGHT |
Japan’s newest rocket configuration is proving itself in space right now! The H3-30 variant uses three powerful LE-9 engines but no solid rocket boosters, making it the lightest version of the H3 family. This test flight carries a dummy main payload called VEP-5 plus five small satellites.
According to NASASpaceflight, this launch marks the H3’s return to flight and debuts the lightest configuration of Japan’s next-generation rocket. The mission tests how well the rocket can reach sun-synchronous orbit without extra boosters.
Falcon 9 — Starlink Group 10-54
| Agency | SpaceX |
| Rocket | Falcon 9 Block 5 |
| Payload | Communications satellites for Starlink internet constellation |
| Orbit | Low Earth Orbit |
| Launch Site | Space Launch Complex 40, Cape Canaveral SFS, FL, USA |

| Status | GO |
SpaceX will launch 29 more Starlink satellites to expand its global internet network. This mission brings the total number of Starlink satellites even closer to providing worldwide coverage. The launch uses a proven Falcon 9 rocket that has completed 295 straight successful flights.
This rocket launch will use booster B1080, which is flying for the 27th time after a 59-day turnaround. The first stage will attempt to land on the drone ship “A Shortfall of Gravitas” in the Atlantic Ocean.
Booster
B1080 is making its 27th flight with 26 previous successful landings. This veteran booster first flew in May 2023 and last launched in April 2026.
What to Watch For
- Japan’s H3-30 testing a lighter rocket design without solid boosters
- SpaceX booster B1080 attempting its 27th landing on a drone ship
- Two different approaches to space access: government test flights vs. commercial satellite deployment
Today shows how the global space industry continues growing with both new rocket designs and reliable workhorses expanding internet access worldwide.
