New Space Station Resupply Vehicle (新型宇宙ステーション補給機, Shingata Uchū Sutēshon Hokyūki), tentatively called HTV-X, is an expendable Japanese cargo spacecraft used for International Space Station (ISS) resupply missions. The spacecraft is under development by Japan Aerospace Exploration Agency (JAXA) as the successor of H-II Transfer Vehicle (HTV).

HTV-X1 is the first flight and the technical demonstration mission of HTV-X, an uncrewed expendable cargo spacecraft. As of 2024, it is intended to be launched in 2025 to resupply the International Space Station (ISS). [3] In addition to the primary mission of carrying the resupply cargo to the ISS, HTV-X1 will carry the following payloads: [2]

它与之前的htv一样由种子岛航天中心发射，不同的是htv-x由h3火箭搭载发射，向在高度约400公里上的国际空间站运送粮食、衣服、各种实验装置等补给物资。以往的htv在补给完成就与iss脱离，随后在几天内受控坠入大气层被烧毁，而htv-x在iss脱离后对接后还能在 ...

HTV货运飞船（H-II Transfer Vehicle，HTV）是日本航空航天探索局（JAXA）专门为 国际空间站 （ISS）计划研发、由 三菱重工 制造的不载人货运飞行器。 2018年8年9月23日2时52分，日本在鹿儿岛县种子岛宇宙中心发射一艘“鹳”号货运飞船，为国际空间站送去小型回收舱等。 [1] 日本HTV货运飞船均命名为“白鹳”（KOUNOTORI）。 在日本传统文化中，白鹳表达了这样一种意象：它在向人们运送一件非常重要的东西（孩子，幸福，或者其它快乐的东西）。 这恰好体现 …

We present below the technical specifications of the HTV-X being developed. The Service Module is the module which integrates all the functions required for the HTV-X to navigate in outer space. It also has functions of transporting exposed cargoes and devices to be used in technical demonstration missions.

HTV-X, the new unmanned spacecraft now being developed by JAXA as the successor to the "Kounotori" (HTV)

The new cargo transporter to the International Space Station (HTV-X) is an unmanned spaceship under development to acquire a spacecraft system with the potential for improving transportation capability and operability, which can be utilized for various missions in the future, while maintaining KOUNOTORI’s superiority.

The HTV-X will transfer essential cargo such as large-sized devices for the ISS and life support goods for astronauts. The costs for the HTV-X will be cut down through compact designing and efficient operations.
