ispace, a global lunar resource development company with the vision, “Expand our planet. Expand our future.”, specializes in designing and building lunar landers and rovers. ispace aims to extend the sphere of human life into space and create a sustainable world by providing high-frequency, low-cost transportation services to the Moon. Toward that vision, we aim to build an economic zone between the Earth and the Moon (cislunar) through the commercialization of lunar surface development.
In 2022, we launched our first mission to the Moon. It was the culmination of years of hard work and our first step towards extending human life into outer space. Mission 2, launched in 2025, was the second and final mission of the HAKUTO-R lunar exploration program and featured the RESILIENCE lunar lander carrying the TENACIOUS micro rover, navigating deep space and entering lunar orbit before attempting to land on the Moon. With the completion of the R&D Phase, ispace moves forward, taking the lessons learned from Mission 1 and Mission 2, and transitioning into its “Early Commercialization Phase" with Missions 3 & 4 currently in development.
ispace has business entities in Japan, Luxembourg, and the United States with more than 300 employees worldwide.
