The Japan Aerospace Exploration Agency is set to launch the uncrewed HTV-X1 cargo spacecraft to the International Space Station. This is the first of a new series of cargo ships by Japan called HTV-X.

The cargo spacecraft will launch atop an H3 rocket from Tanegashima in Japan. Aboard will be nearly 6,000 kilograms of pressurized and unpressurized cargo for the space station’s Expedition 73 crew.

Following launch, the spacecraft is expected to take several days to catch up and rendezvous with the ISS. It will be captured by the outpost’s robotic arm and berthed to the Earth-facing port of the Harmony module where it will stay through the end of the year.

HTV-X is a successor cargo ship to the Japanese HTV spacecraft, which launched nine times between 2009 and 2020.
