JAXA has set MMX for launch at 4:41:03 a.m. on October 20, 2026. The probe lands on Phobos, collects at least 10 grams and returns in fiscal 2031, chasing a first from the Martian system.
Cold sleep was a movie prop. Then ESA calculated that a hibernating crew would cut a Mars spacecraft's mass by a third, and a Japanese lab found the brain switch. With humans, it is still a matter of hours.
ispace and Mitsubishi Heavy will launch the ULTRA lunar lander on an H3 rocket in 2028, with no rideshare. Of the 18.7 billion yen Mission 3 expects to bring in, 12 billion is a government subsidy.
Mice spent two days in artificial hibernation and lost more than half the synapses in the hippocampus, yet still knew where the food was. What survived was not the big connections but the tightly clustered ones.
A lump of iron from a Toyama riverbed turned out to be a meteorite. Enomoto Takeaki had five swords forged from it in 1898, and the same rock later served as a reference for researchers analysing Tutankhamun's dagger.
Japan's H3 Rocket No. 9 put the Michibiki No. 7 satellite into orbit on August 11, 2026, the first operational payload since the No. 8 failure. The seven-satellite goal now waits on fiscal 2031.
A rock punched through a New Jersey ceiling on July 16, 2024. The homeowner sealed the pieces in jars within minutes, letting a team with the Institute of Science Tokyo and JAMSTEC read traces of ancient asteroid brine.
Japanese researchers held 1.58 tesla inside a 20 mm model in a 7 km/s hypersonic flow, about 2.1 times what a comparable neodymium magnet gives. Heat flux itself, though, was not among the measurements.
NAOJ puts NINJA on the Subaru Telescope this summer, a spectrograph that grabs 0.85 to 2.5 micrometers in one exposure. Why Japan bet on follow-up, not discovery.
LEAF, a deorbit device that drags dead small satellites out of orbit, was finished by space startup cosmobloom and Katsuragawa Seira, a Tokyo screw maker in business since 1938. How a town factory's eye ended up on a film thinner than kitchen wrap.
NYK Line, Japan's largest shipping company, is working with Mitsubishi Heavy Industries to catch reusable rocket boosters on a ship at sea. The idea began in an in-house training program, became the first shipping-company project selected for JAXA's Space Strategy Fund, and now faces a question NYK's own engineers raise: will anyone launch often enough to make it pay?
On July 5, Hayabusa2 passed 800 meters from asteroid Torifune at 5 km/s, its first major win since 2020. A look at why Japan keeps flying a retired probe, the road to 1998 KY26, and how it compares to NASA's OSIRIS-APEX.
Resonac, BEAM and Nippon LEO signed an MOU to manufacture compound semiconductors in low Earth orbit. Why build chips in microgravity, and how Japan's bet compares to the US and China.
On June 26, 2026, Japan's Diet passed a law renaming the Air Self-Defense Force as the Aerospace Self-Defense Force, the first rename of an SDF branch since 1954. A new 880-strong Space Operations Command will track satellites and threats in orbit. Here is what changes, and why now.
JAXA will launch the Michibiki No. 7 satellite on H3 Rocket No. 9 on August 7. A look at Japan's GPS-independent seven-satellite plan, the ASNAV system that aims to take phone accuracy from 5-10 meters to 1, how it compares with GPS, Galileo and BeiDou, and the satellite Japan just lost.
HOKUSHIN-1, a cubesat from three Japanese universities, was deployed from the ISS on June 19. Why it proves deep-space tech in low orbit first, where failure is cheap.
Since 2016, a Japan-led ALMA team kept breaking distance records for oxygen in the early universe. In 2026 they finally caught the cold neutral gas itself: [O I] 145μm in four galaxies ~13 billion years back. The decade-long quest, and how it complements the Webb-led race.
New image analysis confirms Japan's 228-gram transformable robot SORA-Q (LEV-2) moved about 0.13m and turned 180 degrees on the Moon entirely on its own, earning a Science Robotics cover. Built with help from a toy maker, the palm-sized machine opens a new path for small-scale exploration aimed at caves, steep slopes and, eventually, Mars.
Mitsubishi Electric is building an orbital transfer vehicle under Japan's Space Strategy Fund. We map the race: America's speed-and-price game led by Impulse Space, China's dual-use Shijian maneuvers, and Japan's unconventional bet on the docking skills it honed resupplying the ISS.
A Tohoku University team grew rice to the heading stage in soil mimicking the Moon's surface, using fertilizer made from nothing but air and electricity via plasma. The unlikely inspiration? Gundam's beam saber. As NASA pushes toward a lunar base, it could become foundational tech for growing food in space.
