HTV-X1 Set for ISS Departure With Scheduled NASA/JAXA Coverage

NASA and JAXA’s HTV-X1 cargo spacecraft is slated to depart the International Space Station on March 6 after delivering about 12,000 pounds of cargo; undocking on March 5 will be performed by Canadarm2, with live coverage starting at 11:45 a.m. EST before the 12 p.m. release. NASA will not provide live coverage of the undocking. HTV-X1 will remain in orbit for more than three months as a platform for JAXA experiments and will burn up upon reentry, disposing of several thousand pounds of trash. HTV-X1 arrived at the ISS on Oct. 29, 2025, after a Oct. 25 launch on an H3 rocket from Tanegashima.

Japan's H3 rocket loses Michibiki 5 after payload fairing detaches in flight

JAXA's seventh H3 launch failed when the payload fairing detached about four minutes after liftoff, leaving the Michibiki 5 navigation satellite to fall back into the Pacific; investigators are probing the cause, and the anomaly could delay future H3 missions and planned payloads like MMX and HTV-X.

Japan’s H3 rocket loses 5-ton Michibiki 5 satellite after payload fairing separation

Japan’s eighth H3 rocket failed after its payload fairing separated, causing the roughly 5-ton Michibiki 5 navigation satellite to be lost in Pacific debris; telemetry hints at a LH2 tank pressure drop and possible damage to the satellite mounting, with investigators considering a fairing–satellite impact or residual stress as potential causes. The second stage briefly placed the vehicle in a low-altitude orbit before reentry hours later, and Japan’s MMX mission launch remains awaiting a full investigation before proceeding.

Japan’s Akatsuki Venus Orbiter Quieted After 15-Year Mission, Revealing the Solar System’s Largest Gravity Wave

Japan’s Akatsuki Venus orbiter, launched in 2010, ended operations in September 2025 after a dramatic comeback from a failed entry and a five-year drift. During more than a decade in Venus orbit it mapped the atmosphere in UV and IR, advanced understanding of super-rotation, and documented a 6,200-mile-long stationary gravity wave—the largest in the Solar System—before mission control shut down and archived the data for future study.

Venus Loses Its Last Active Spacecraft, Ending Human Presence

The Japanese spacecraft Akatsuki, which studied Venus since 2010 and provided valuable data, has been officially declared dead after losing contact in 2024, marking Japan's first successful planetary exploration. Despite setbacks, it exceeded its expected lifespan, and future missions by NASA and ESA are planned to continue Venus research. Until then, Earth’s connection to Venus is temporarily severed.

Japan's HTV-X Cargo Craft Debuts as Space Lab and Supplies ISS

Japan's Aerospace Exploration Agency (JAXA) successfully docked its new cargo spacecraft, HTV-X, at the ISS, marking a significant milestone. The spacecraft, designed to serve as both a cargo carrier and a temporary space lab, carried supplies, experimental equipment, and new technology demonstrations, with plans for its use after leaving the ISS, including trash disposal and hosting equipment for extended periods. This mission also highlights Japan's advancements in space technology and its ongoing contributions to international space efforts like the Artemis Program.
