The Japan Timesreports that Interstellar Technologies fourth launch of is Momo rocket failed on Saturday.
The vehicle only reached an altitude of 13 kilometers following the launch at 4:20 p.m., falling into the sea some 9 kilometers (about 5.5. miles) offshore from Taiki, Hokkaido, its test site, Interstellar Technologies said.
The rocket is the same model as Momo-3, measuring about 10 meters long, 50 centimeters in diameter and weighing 1 ton.
After failed attempts in 2017 and 2018, the startup finally found success with its third launch in May, with the rocket reaching an altitude of around 113 km before falling into the Pacific Ocean.
Founded in 2013 by former Livedoor Co. President Takafumi Horie, Interstellar Technologies aims to develop low-cost commercial rockets to carry satellites into space.
The third time was the charm for Interstellar Technologies.
On Saturday, the company’s suborbital Momo-3 rocket lifted off from its launch pad in Hokkaido and reached an altitude of 110 km (68.4 miles) before falling into the Pacific Ocean about 10 minutes later, The Japan Timesreports.
“It was a complete success. We’ll work to achieve stable launches and mass-produce (rockets) in quick cycles,” company founder Takafumi Horie told The Japan Times.
Measuring 10 meters in length and 50 centimeters in diameter and weighing 1 ton, it was first due to be launched Tuesday, but that launch was shelved due to a glitch in the fuel system.
It was the venture company’s third launch attempt after previous tries failed in 2017 and 2018. In 2017, the operator lost contact with Momo-1 shortly after launch. In 2018, Momo-2 only made it some 20 meters off the ground before crashing and bursting into flames due to a problem with a control system.
The MOMO sounding rocket is designed to carry a payload weighting up to 20 kg (44 lb) on suborbital flights at a cost of approximately ¥50 million (~$450,000).
Interstellar is also developing the ZERO booster to carry payloads weighing up to 100 kg (220.5 lb) to a 500 km (310.7 mile) sun synchronous orbit. The company hopes to conduct ZERO’s first flight test in 2020.

The outlandish, Ferrari-driving Horie — who helped drive Japan’s shift to an information-based economy in the late 1990s and the early 2000s but later spent nearly two years in jail for accounting fraud — founded Interstellar in 2013. However, privately backed efforts to explore space from Japan have so far failed to compete with the government-run Japan Aerospace Exploration Agency.
