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.
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.
From mid-August 2026 SoftBank will fly a 65-metre helium airship from New Mexico across the Pacific and hold it about 20 km above Japan, testing voice, SMS and data from a flying base station that covers up to 200 km across. Commercial service is targeted from 2027. Here is how it differs from satellite direct-to-phone, why Loon died, and the business problem SoftBank has not solved.
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.
Kushiro Airport in Hokkaido is the first in Japan to fully deploy WOLF-GUARD, a self-driving version of the famous Monster Wolf robot. In trials, the Monster Wolf cut small-animal intrusions by about 60 percent. Here's how the red-eyed, howling patroller works, and how it compares with the falcons, border collies and radar used at airports abroad.
