ESA and JAXA Seal Ramses Collaboration to Study Apophis Before the 2029 Flyby

The European Space Agency and the Japan Aerospace Exploration Agency have formalized a Ramses collaboration to study asteroid Apophis during its 2029 Earth flyby: Ramses is set to launch in 2028 on an H3 rocket, with JAXA supplying solar arrays and a thermal infrared imager and OHB Italia as prime contractor. The mission would reach Apophis in February 2029, about two months before its close approach to Earth at roughly 32,000 kilometers, enabling detailed observations of the asteroid’s surface and the flyby’s gravitational effects for science and planetary defense insights.

ESA and JAXA Unite on Ramses: A Historic Mission to Study Apophis and Boost Planetary Defense

ESA and JAXA signed an agreement to launch the Ramses mission to the near-Earth asteroid Apophis, with a planned 2028 launch and a 2029 rendezvous during its close Earth flyby at about 32,000 km. The mission aims to study how Apophis behaves under Earth's gravity and to collect data that could improve asteroid deflection and monitoring strategies, informing future planetary-defense efforts. ESA will lead spacecraft design and operations, JAXA will contribute lightweight solar arrays and an infrared imager, and ESA’s NEO Coordination Centre will refine orbital predictions ahead of the flyby. This collaboration showcases international partnership as a cornerstone of global space safety.”,

Rocket Lab launches eight satellites for JAXA, including origami-fold antenna

Rocket Lab’s 79th Electron launch lifted off from New Zealand on April 22, deploying eight satellites for Japan’s JAXA as part of the Innovative Satellite Technology Demonstration Program. The mission, Kakushin Rising, includes educational smallsats, an ocean-monitoring satellite, a multispectral-camera demonstration, and a deployable origami antenna that unfurls to 25 times its packed size. The payloads were placed into a ~540 km low Earth orbit about an hour after liftoff, following JAXA’s earlier RAISE‑4 mission.

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

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 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.

Japanese Astronaut Captures Stunning Aurora from Space Station

Japanese astronaut Kimiya Yui captured stunning photos of auroras and the Milky Way from the ISS's Kibo module, sharing a unique view of space. He is also preparing for Japan's first next-generation HTV-X cargo vehicle launch, scheduled for October 20, 2025, using the station's robotic arm. The ISS remains crewed with seven members, continuing its long history of human presence in space despite ongoing U.S. government shutdown impacts.
