Japan's space agency on Tuesday postponed the launch of its next-generation rocket planned for this week due to expected bad weather, after two previous attempts ended in failure.
The H3 rocket had been scheduled to lift off on Thursday from the southern island of Tanegashima.
Billed as a flexible and cost-effective new flagship, it was to carry two small satellites during the mission, intended to prove it can get into orbit.
"As the weather that day is expected to worsen, we decided to postpone the launch," the Japan Aerospace Exploration Agency (JAXA) said, adding that a new date would be announced "once a decision is made".
Japan succeeded in landing its SLIM spacecraft nicknamed the "Moon Sniper" on the lunar surface last month, although the craft's solar panels were facing the wrong way.
Before that, the country suffered a series of space failures.
They included the first H3 launch attempt in February last year - already delayed by several years - which was abandoned when the solid rocket boosters did not ignite.
Then, at the second attempt in March, the spacecraft was ordered to self-destruct when the command centre concluded its mission could not succeed.
Developed by Mitsubishi Heavy Industries, the H3 is the successor to Japan's H-IIA launch system, which debuted in 2001.
Meanwhile, last February, Japan introduced its newest astronaut recruits for more than a decade to the public for the first time, Japan’s public broadcaster, NHK, reported.
Suwa Makoto and Yoneda Ayu were chosen as the candidates in February 2023.
