Interstellar Technologies, Inc. (Japanese: インターステラテクノロジズ(株), Hepburn: Intāsutera Tekunorojizu (kabu)) is a Japanese NewSpace company. It is a rocket spacelaunch company developing the MOMO launcher. Its stated goal is to reduce the cost of access to space.[1] In 2017, it became the first Japanese company to launch a privately developed space rocket, though the launch was unsuccessful. The company plans to complete a rocket by 2020 that would be capable of launching small satellites into orbit.[2] As of 2018, the president is Takahiro Inagawa.[3]

As of 2018, the company has managed to raise about ¥30 million (about US$250,000) in crowdfunding.[4]


The group that became Interstellar Technologies was created as a hobbyist organization in 1997.[5] Interstellar Technologies predecessor company was established in 2003 by Takafumi Horie, who previously founded the ISP Livedoor. It was established to develop rockets to launch small satellites. It became Interstellar Technologies in 2005. Interstellar plans to lower the cost of access to space,[1][3][6] and is attempting to have the first privately developed rocket in Japan to reach space.[4]

On 30 July 2017, the MOMO-1 rocket failed after launch. Contact was lost 66 seconds after launch, triggering an emergency engine shutdown. The rocket reached an altitude of 20 km (12 mi). This represented the first privately funded space rocket to be launched in Japan. The launch cost about ¥50 million (US$440,000).[1][2][3][4]

In March 2018, Interstellar entered into a business alliance with Nippon Travel Agency and Space Development Corp.[7] In May 2018, Interstellar received an investment of ¥19.8 million from Kushiro Manufacturing.[7]

On 30 June 2018, at 5:30am local time, the MOMO-2 rocket was launched from Taiki, Hokkaido, Japan, lifting off the pad. Four seconds later, it came crashing back down onto it, exploding violently.[3][4][6]

On 04 May 2019 (JST), at 0545 JST, MOMO-3 rocket was launched from Taiki, Hokkaido, Japan, lifting off the pad and reaching 113.4 km of apogee and making it the first commercially developed Japanese rocket to reach Kármán line.[8][9]
