Japanese aerospace startup Interstellar Technology Inc. said a small rocket it launched Saturday morning has succeeded in reaching outer space.

Following its successful launch after two postponements earlier this week, the unmanned MOMO-3 became Japan’s first privately developed rocket to accomplish the feat.

The MOMO-3 was launched at around 5:45 a.m. at the venture company’s site on Japan’s northernmost main island of Hokkaido. It is the company’s third launch attempt after previous tries failed in 2017 and 2018.
