ispace Moon Lander Breaks Up After Losing Contact

Japanese space startup ispace announced on June 6 that its second lunar lander had failed in its attempted moon landing earlier that morning. The mission was aiming to become the first private Asian lunar landing.
Based in Tokyo's Minato Ward, the space technology company had developed the lunar lander in-house. According to the company spokesperson, communication with Earth was lost just before the scheduled touchdown at 4:17 AM. ispace believes the lander crashed and suffered serious damage, rendering it inoperable.
According to the company, the lander exited its circular lunar orbit at around 3:15 AM from an altitude of about 100 kilometers. It began a controlled descent lasting roughly one hour, firing its main and auxiliary engines to slow down and stabilize. The intended landing site was the "Sea of Ice" near the Moon's north pole.

With constant monitoring, the lander was tracked down to an altitude of 192 meters. Soon after, however, communication was lost. Despite efforts to restore contact communications, no signal had returned by 9:00 AM. At that point, ispace concluded the spacecraft had crashed and broken apart on the lunar surface.
Flight data showed a fault in the altitude measurement system, which likely delayed deceleration. However, the exact cause is still unknown. ispace's first lander also failed in 2023 due to a similar issue. Although improvements were made, a repeat malfunction may have occurred.
CEO Takeshi Hakamada, speaking with a somber expression, said: "We take these two failures very seriously. We will fully investigate the cause and evaluate whether our fixes were adequate."

NASA spacecraft around the moon photographs the crash site of a Japanese company's lunar lander
This image provided by NASA shows an annotation indicating the impact site for ispace's Resilience lunar lander, seen by the Lunar Reconnaissance Orbiter Camera on June 11, 2025. (NASA/Goddard/Arizona State University via AP) CAPE CANAVERAL, Fla. — A NASA spacecraft around the moon has photographed the crash site of a Japanese company's lunar lander. NASA released the pictures Friday, two weeks after ispace's lander slammed into the moon. The images show a dark smudge where the lander, named Resilience, and its mini rover crashed into Mare Frigoris or Sea of Cold, a volcanic region in the moon's far north. A faint halo around the area was formed by the lunar dirt kicked up by the impact. NASA's Lunar Reconnaissance Orbiter captured the scene last week. The crash was the second failure in two years for Tokyo-based ispace. Company officials plan to hold a news conference next week to explain what doomed the latest mission, launched from Cape Canaveral in January. Marcia Dunn, The Associated Press

Fujitsu awarded contract to design next-generation flagship supercomputer FugakuNEXT
Accelerating scientific and technological innovation with Made-in-Japan CPU technology KAWASAKI, Japan, June 18, 2025 /CNW/ -- Fujitsu Limited today announced that it has been awarded a contract by the Japanese research and development institute RIKEN to design a next-generation flagship supercomputer. The contract for the supercomputer, provisionally named "FugakuNEXT," encompasses the overall system, computing nodes, and CPU components and the basic design phase is scheduled to run until February 27, 2026. Supporting Japan's leadership in science and technology with a next-generation computing platform The rapid growth of generative AI and other technologies is driving increased demand for diverse and large-scale computing resources for R&D. According to a report by the HPCI Steering Committee established by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), the importance of "AI for Science," i.e., initiatives that combine AI with simulation technology, real-time data, and automated experiments, is increasing, prompting nations to prioritize advanced computing infrastructure. Japan needs a new, flexible platform that will address these evolving demands, enable its leadership in science, technology, and innovation and facilitate further societal and industrial advancement. The HPCI Program Steering Committee has chosen RIKEN as the primary entity responsible for developing this platform, and RIKEN has chosen Fujitsu to design it. Building a foundation for future innovation with advanced CPU design FugakuNEXT will leverage Fujitsu's established supercomputing expertise, incorporating advanced technologies from the FUJITSU-MONAKA3 general-purpose CPU currently under development, and will cater to evolving customer needs by allowing for seamless integration with GPUs and other accelerators. FUJITSU-MONAKA, built on leading-edge 2-nanometer technology, employs Fujitsu's unique technologies, including a microarchitecture optimized for advanced 3D packaging and ultra-low voltage circuit operation. It aims to deliver both high performance and power efficiency across diverse next-generation computing applications, from edge computing to data centers, while ensuring safety, security, and ease of use. The successor CPU to FUJITSU-MONAKA, tentatively named "FUJITSU-MONAKA-X," intended for use in FugakuNEXT, will not only inherit and accelerate existing Fugaku application assets but also incorporate state-of-the-art AI processing acceleration capabilities to meet growing AI demands. This CPU is intended for broad application across sectors supporting society and industry, extending beyond its role in FugakuNEXT. Through its core, Made-in-Japan CPU technology, Fujitsu will continue to deliver innovation and build trust, contributing to a world-class computing infrastructure and advancing Japanese science and technology.
