可重复使用的探空火箭的主发动机是在日本宇宙航空研究开发机构的阁田航天中心开发的。2014年6月至2015年2月共进行了54次发动机点火实验。通过这些实验，证明了该发动机的先进性能和功能，如大范围节流、精确可控和健康监测是可行的。这枚火箭还被要求可重复使用100多次飞行。为了确认这种发动机在有限的试验期内能够进行100多次飞行的长寿命耐久性，计划并进行了连续多次发射试验。并对主腔室的火灾损伤进行了数值分析。耐久性试验和数值分析结果表明，该发动机可重复使用100多次飞行。
The main engine of the reusable sounding rocket has been developed at the Kakuda Space Center of the Japan Aerospace Exploration Agency. A total of 54 engine firing experiments were conducted between June 2014 and February 2015. Throughout these experiments, the advanced capabilities and functions of this engine, such as wide-range throttling, accurate controllability, and health monitoring, were proved to be feasible. This rocket was also required to be reusable for over 100 flights. To confirm the long-life durability of this engine for over 100 flights in a limited experiment period, sequential multiple-firing tests were planned and conducted. Numerical analysis to evaluate damage of the main chamber due to firings was also conducted. The results of the durability tests and numerical analysis showed reuse of this engine for over 100 flights to be feasible.
