Japan Successfully Launches New Cargo Spacecraft to Resupply International Space Station
October 26, 2025
Japan’s space agency has achieved another major milestone in space exploration after successfully launching its new H3 rocket, carrying the HTV-X1 unmanned cargo spacecraft on its first mission to deliver supplies to the International Space Station (ISS).
The Japan Aerospace Exploration Agency (JAXA) confirmed that the H3 (No. 7) rocket lifted off smoothly from the Tanegashima Space Center in southern Japan early Sunday morning. The launch marks a significant step forward in Japan’s efforts to strengthen its presence in international space logistics and technology innovation.
The HTV-X1 spacecraft, also known as Kounotori X, is designed to deliver essential equipment, experiments, and daily supplies to astronauts aboard the ISS. The new-generation cargo vehicle will replace the previous H-II Transfer Vehicle (HTV) series, offering enhanced efficiency, greater payload capacity, and improved reusability for future missions.
This launch demonstrates Japan’s growing capabilities in space transportation and engineering. The H3 rocket, developed by JAXA and Mitsubishi Heavy Industries, serves as the country’s new flagship launch vehicle, designed to make space access more cost-effective and sustainable.
According to JAXA officials, after completing its journey to the ISS, the HTV-X1 will conduct multiple experiments and tests to prepare for future deep-space missions. The agency hailed the mission as a success and a key step toward Japan’s long-term goal of supporting lunar and Mars exploration under international partnerships.
With this successful launch, Japan joins a select group of nations actively contributing to ISS resupply missions, reinforcing its role as a trusted partner in global space exploration efforts.
