Summary:

Japan’s space agency, JAXA, successfully launched its new H3 rocket carrying the HTV-X1 cargo spacecraft on October 26, 2025. This marks the first mission for the HTV-X, designed to deliver supplies to the International Space Station (ISS) and succeed the earlier H-II Transfer Vehicle “Kounotori.” The HTV-X boasts increased payload capacity, in-flight power supply, and an extended mission profile including waste retrieval and orbital experiments. The H3 rocket, after a previous failure, has now achieved six consecutive successful flights and is intended to be a cost-effective and reliable replacement for the H-2A rocket in the competitive global space market.

Japan Launches New H3 Rocket, Sending Cargo Spacecraft to ISS

Tokyo – October 26, 2025 – Japan Aerospace Exploration Agency (JAXA) celebrated a successful launch of its H3 rocket early Sunday morning, carrying the HTV-X1 cargo spacecraft on its maiden voyage to the International Space Station (ISS). Lift-off occurred at the Tanegashima Space Center in southern Japan, marking a significant milestone for the nation’s space program.

The HTV-X1, the successor to the H-II Transfer Vehicle “Kounotori” which completed nine missions to the ISS between 2009 and 2020, successfully separated and achieved its planned orbit, according to JAXA officials. It is expected to arrive at the ISS within days, delivering crucial supplies and equipment to the orbiting laboratory. Japanese astronaut Kimiya Yui is scheduled to use a robotic arm to capture the spacecraft on Thursday.

The new HTV-X boasts an increased payload capacity compared to its predecessor and offers the capability to supply power during flight, allowing for the transport of temperature-sensitive materials like cell samples. After its initial delivery, the HTV-X is designed to remain docked at the ISS for up to six months, retrieving waste and conducting technical experiments in orbit following its departure from the station.

The H3 rocket, intended as a cost-effective and commercially competitive replacement for the retiring H-2A rocket, has now achieved six consecutive successful launches following a setback in 2023. JAXA views the stable and competitive space transport capability the H3 provides as vital for Japan’s space program and national security interests.
