Mitsubishi Electric Corp. recently showcased its essential role in the development of the HTV-X cargo spacecraft, which aims to succeed the retired Kounotori HTV vehicle in ferrying supplies to the International Space Station. Based on the unveiling at the company's facility in Kamakura, Kanagawa Prefecture, it is evident that Mitsubishi Electric is responsible for the primary components ensuring the spacecraft's operational functions during flight, including power, control, and communication systems.

In addition to Mitsubishi Electric's contribution, Mitsubishi Heavy Industries Ltd. is focused on the cargo hold aspect of the HTV-X, essential for transporting supplies and equipment to the ISS. The new spacecraft, set to be launched in fiscal 2025 onboard the H-3 launch vehicle, is designed to have increased cargo transport capability compared to its predecessor, the Kounotori HTV, which served the ISS for approximately 15 years before its retirement in 2020. With a length of 8 meters and a weight of about 16 tons, the HTV-X is expected to provide 1.5 times the cargo capacity of the previous HTV vehicle, ensuring more efficient supply missions to the space station.

Looking ahead, there are discussions about potential modifications to the HTV-X to enable it to transport supplies to the Gateway, a lunar space station forming part of the Artemis manned lunar mission program initiated by the United States. This adaptability showcases the spacecraft's versatility and future readiness to support upcoming space exploration endeavors beyond the International Space Station, further solidifying Mitsubishi Electric's vital role in advancing space transportation technology.
