Japan's H3 rocket is poised to return to flight with its debut launch of the lightest configuration, following a hiatus. This launch marks a pivotal moment for the Japan Aerospace Exploration Agency (JAXA) as it aims to enhance its launch vehicle capabilities. The H3 rocket, developed to replace the H-IIA, is designed to offer more flexible payload options and reduced launch costs.

Recent orbital data indicates a close approach between COSMOS 2581 and COSMOS 2583, with a minimum distance of approximately 0.16 km. Such proximity highlights the increasing need for effective space traffic management. Additionally, the FENGYUN 1C debris has shown significant changes in its orbital parameters, suggesting potential manoeuvres or anomalies. These developments can be further explored using the Debris Map on Orbital Radar.

What to Watch

While no launches are scheduled for today, Vandenberg Space Force Base has announced a new launch site for small and medium rockets, expanding its capabilities. This development could influence future launch schedules, which can be monitored on the Launch Schedule page.
