The privately developed Japanese sounding rocket MOMO-F4 has fallen into the ocean due to early engine shutdown shortly after takeoff, the Japanese space company Interstellar Technologies (IST) said on Saturday.

Axar.az reports the IST said that, "Due to an abnormality of the spacecraft's on-board computer systems, the engine automatically shut down and the rocket safely splashed down to the ocean."

MOMO-F4’s launch and flight was streamed live on social media.

Interstellar Technologies earlier successfully launched the country's first private rocket, dubbed MOMO-3 in May. Two previous launches in July 2017 and in June 2018 failed.

MOMO-4 is a 10-metre long rocket with a diameter of 50 centimetres. It can carry surveillance devices weighing up to 20 kilograms. The launch was initially scheduled for 20 July, but had to be cancelled due to technical problems.

While MOMO cannot put satellites into orbit, the company plans to create a rocket capable of launching satellites and conduct the first launch by 2023.
