东京-星际技术公司(代表董事:稻川隆宏，以下简称“IST”)和日本宇宙航空研究开发机构(主席:山川宏，以下简称“JAXA”)对空间相关产品有了新的想法。在“JAXA空间创新伙伴关系”(J-SPARC)的框架下，我们开始了与小型火箭发动机系统技术研发有关的共同创造活动。从2019年2月起，IST和JAXA将通过J-SPARC的共同创造活动(第一阶段)，瞄准小型火箭发动机的主要部件喷油器、燃烧室和涡轮泵。在这次共创活动中，将利用JAXA角田航天中心的试验设备，JAXA将把迄今为止在火箭发动机研究中获得的技术，作为未来的基础技术，进行社会实施和小型火箭发动机技术的研发。目前正在研制的超小型人造卫星运载火箭“ZERO”(以下简称“ZERO”)假设采用火箭发动机，IST已制定了规范并研发了技术。在Kakuda航天中心的共同创造活动(第一阶段)喷油器特性测试实例:从2019年开始，在JAXA Kakuda航天中心进行了低成本和高可操作性喷油器的地面燃烧测试。我们成功地展示了设计技术，获得了性能。现在我们已经有了将这些主要部件技术投入实际使用的前景，作为下一个共同创造活动(第二阶段)，我们将研究和开发一种用于小型火箭的发动机系统，将每种技术集成为一个系统。我决定着手解决这个问题。在这一阶段，JAXA和IST将各自设计和制造组成发动机系统的部件，JAXA将在角田航天中心组装和测试发动机系统，获得的测试结果将由双方共享。 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.
