Japan’s space agency has said its planned launch of a satellite on its new flagship H3 rocket this weekend will be postponed until Monday due to expected bad weather.
The Japan Aerospace Exploration Agency, or Jaxa, said it was postponing the launch because of rain and thunder predicted for Saturday night when the rocket was to be moved to the launch site at the Tanegashima Space Centre on a southwestern Japanese island.
The launch was initially scheduled for Sunday.

The weather did not meet the required condition, therefore, the launch date has been changed for July 1, 2024 (Mon)

The rocket will be carrying an Advanced Land Observation Satellite, ALOS-4, tasked primarily with Earth observation and data collection for disaster response and map-making, as well as with monitoring military activity, such as missile launches, with an infrared sensor developed by the country’s defence ministry.
The ALOS-4 is a successor to the current ALOS-2 and can observe a much wider area. Japan will operate both for the time being.
The launch will be the H3’s third, after a successful launch on February 17 that followed a failed debut flight a year earlier when the rocket had to be destroyed with its payload — a satellite that was supposed to be the ALOS-3.
Japan sees a stable, commercially competitive space transport capability as key to the country’s space programme and national security.
Jaxa and its main contractor Mitsubishi Heavy Industries (MHI) have been developing H3 as a successor to its current mainstay, H-2A, which is set to retire after two more flights.
MHI will eventually take over H3 production and launches from Jaxa and hopes to make it commercially viable by cutting the launch cost to about half of the H-2A.
