iSpace Selects MHI H3 Rocket for 2028 Lunar Lander Mission with “ULTRA”

The Japan Times Japan

Overview

Japanese lunar exploration company iSpace has signed a contract with Mitsubishi Heavy Industries (MHI) to launch its new “ULTRA” lunar lander aboard an H3 rocket in 2028. This marks iSpace’s first mission utilizing a domestic Japanese launch vehicle, signaling a significant step towards a fully integrated lunar transportation system within Japan’s burgeoning space industry. This collaboration is expected to accelerate the development of a domestic lunar transport system and enhance Japan’s role in future lunar exploration.

In Depth

Key Findings

Japanese lunar exploration startup iSpace has officially signed a contract with Mitsubishi Heavy Industries (MHI) to launch its new “ULTRA” lunar lander aboard an MHI H3 rocket in 2028. This agreement represents iSpace’s inaugural mission utilizing a domestically produced launch vehicle, significantly advancing the strengthening of domestic cooperation within Japan’s space industry and the establishment of a comprehensive lunar transportation system.

Technical Details

iSpace’s “ULTRA” lunar lander is designed to transport larger payloads to the lunar surface, expected to play a crucial role in future lunar exploration and resource development missions. The H3 rocket, developed jointly by JAXA and MHI, is Japan’s next-generation flagship launch vehicle, characterized by its high reliability and cost-effectiveness. The H3 is rapidly establishing its position as a core rocket supporting Japan’s space infrastructure due to its launch capabilities and stability.

Background & Context

While previous iSpace lunar missions have utilized foreign rockets, this collaboration with MHI will accelerate the localization of the entire supply chain. This is a critical step for Japan’s space industry in building an integrated domestic ecosystem from launch to lunar landing and exploration. Amid increasing government support for domestic space activities, such as the government’s Space Strategy Fund and the Ministry of Defense’s satellite constellation projects, this private-sector cooperation is expected to further boost the growth of Japan’s space market.

Strategic Significance & Outlook

The successful launch of “ULTRA” in 2028 will not only demonstrate iSpace’s capability to provide lunar transportation services but also showcase the technological prowess and international competitiveness of Japanese private space companies. Future plans envision high-precision landings in unexplored regions, such as the lunar south pole, and contributions to infrastructure development for long-term lunar bases. iSpace’s trajectory as a central player in Japan’s lunar strategy will be closely watched.
