Aerospace startup Interstellar Technology Inc. said it postponed the planned launch of a small rocket on Thursday due to strong wind.
The unmanned Momo-3 was originally scheduled to blast off on Tuesday, but that was thwarted by a fuel-system glitch.
Interstellar Technology said the launch from its test site in Hokkaido would be rescheduled for Friday or later.
If successful, the Momo-3 would be Japan's first privately developed rocket to reach outer space.
