We have loaded HTV-X1 into the fairing of the H3 rocket! This is the last chance to see the full view of HTV-X1 on the ground.

We'll carefully wrap it in the fairing and deliver it to space.

Decals of "H3" and "HTV-X No. 1" have been applied to the fairing of the H3 Rocket No. 7!

HTV-X is a supply ship to the ISS. This time, with the meaning of "delivering your luggage," it even comes with a baggage tag.

What is the message hidden in the numbers readable from the barcode...?

Coverage will stream on our YouTube channel at 7:45 p.m. EDT, and NASA will provide minimal technical commentary as this activity relates to excepted mission operations.

The unpiloted HTV X-1 spacecraft is scheduled to launch at 8 p.m. EDT (9 a.m. on Sunday, Oct. 26, Japan time). The HTV-X1 spacecraft will be placed into an orbit for a multi-day journey to the space station, culminating in its capture with the Canadarm 2 robotic arm operated by JAXA’s Kimiya Yui and NASA’s Zena Cardman.

NASA will also provide coverage of the HTV-X1 rendezvous at 9:05 a.m. on Wednesday, Oct. 29, for a capture at 11:50 a.m.

Launch result of HTV-X1 aboard H3 launch vehicle

Japan Aerospace Exploration Agency (JAXA) launched the new unmanned cargo transfer spacecraft1 (HTV-X1) aboard the 7th H3 Launch Vehicle (H3 F7) at 9:00:15 a.m. JST on Oct. 26, 2025 [8:00 p.m. EDT on Oct. 25 or 0000 GMT on Oct. 26] from the Tanegashima Space Center.

The Launch Vehicle flew as planned, and approximately 14 minutes and 4 seconds after the liftoff, the separation of HTV-X1 was confirmed.

Following its separation from the launch vehicle, communications and attitude control of HTV-X1 were confirmed, and the vehicle is now flying smoothly toward its arrival at the ISS.

JAXA expresses its sincere appreciation for the support and cooperation extended by all those involved in the successful launch of HTV-X1.

HTV-X1 is scheduled to arrive at the ISS on October 30 (JST). Capture by the robotic arm "Canadarm2" on the ISS is planned for around 0:50 a.m. [11:50 a.m. EDT or 1550 GMT on Oct. 29], followed by berthing to the ISS.

Japan's first advanced cargo ship, HTV-X1, arrives at the International Space Station

For the first time in five years, a Japanese spacecraft has arrived at the International Space Station.

JAXA (the Japan Aerospace Exploration Agency) on Wednesday (Oct. 29) oversaw the HTV-X1, its first upgraded cargo ship, as it was captured and berthed to the orbiting complex. Japanese astronaut Kimiya Yui and NASA astronaut Zena Cardman, members of the Expedition 73 crew, used the station's Canadarm2 robotic arm to grapple the solar-powered spacecraft at 11:58 a.m. EDT (1558 GMT or 12:58 a.m. Japan Standard Time on Oct. 30).
