東京-星際技術公司(代表董事:稻川隆宏，以下簡稱“IST”)和日本宇宙航空研究開發機構(主席:山川宏，以下簡稱“JAXA”)對空間相關產品有了新的想法。在“JAXA空間創新夥伴關係”(J-SPARC)的框架下，我們開始了與小型火箭發動機係統技術研發有關的共同創造活動。從2019年2月起，IST和JAXA將通過J-SPARC的共同創造活動(第一階段)，瞄準小型火箭發動機的主要部件噴油器、燃燒室和渦輪泵。在這次共創活動中，將利用JAXA角田航天中心的試驗設備，JAXA將把迄今為止在火箭發動機研究中獲得的技術，作為未來的基礎技術，進行社會實施和小型火箭發動機技術的研發。目前正在研製的超小型人造衛星運載火箭“ZERO”(以下簡稱“ZERO”)假設采用火箭發動機，IST已製定了規範並研發了技術。在Kakuda航天中心的共同創造活動(第一階段)噴油器特性測試實例:從2019年開始，在JAXA Kakuda航天中心進行了低成本和高可操作性噴油器的地麵燃燒測試。我們成功地展示了設計技術，獲得了性能。現在我們已經有了將這些主要部件技術投入實際使用的前景，作為下一個共同創造活動(第二階段)，我們將研究和開發一種用於小型火箭的發動機係統，將每種技術集成為一個係統。我決定著手解決這個問題。在這一階段，JAXA和IST將各自設計和製造組成發動機係統的部件，JAXA將在角田航天中心組裝和測試發動機係統，獲得的測試結果將由雙方共享。 In this way, we aim to efficiently acquire a wide range of test data and acquire practical engine system technology at low cost, compared to conducting each independently. IST will utilize low-cost engine system technology for small rockets for the development of ZERO, aiming for early launch of the actual machine. JAXA will accumulate the acquired results as basic technology and contribute to the development of the space transportation business in Japan as a whole, such as the private space transportation service business and the application of JAXA to future space transportation systems.

Phase 1 of this co-creation activity has produced a number of achievements that can achieve both high performance for flights and innovative cost reduction, and I feel that we are steadily taking steps toward orbit insertion. It is our responsibility to bring the results to fruition as an engine system and implement them in society as a rocket. I would like to continue taking on challenges with everyone at JAXA. Interstellar Technologies Inc. Interstellar Technologies Inc. is a startup company that aims to realize a future in which everyone can reach space by building infrastructure for space through overwhelmingly low-priced and convenient space transportation services. am. Headquartered in Taiki-cho, Hokkaido, we are proceeding with development at four bases: the Tokyo branch office, the Fukushima branch office, and the Muroran Institute of Technology (inside Muroran Institute of Technology). The sounding rocket “MOMO” reached outer space for the first time in a domestic private company in May 2019, and succeeded in reaching outer space for two consecutive aircraft in July 2021. The next-generation microsatellite launch rocket “ZERO” is also in full swing for the launch of the first aircraft. JAXA Space Innovation Partnership (J-SPARC) J-SPARC begins with a dialogue between JAXA and private businesses aiming for space business, and with the commitment of both parties toward commercialization, jointly considers the business concept. This is a program to create new businesses by developing and demonstrating technology that is oriented toward exits and exits. Started in May 2018, we have been promoting more than 30 projects and activities so far.
