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 Venus Probe Disappears Without a Trace"

Japan's Akatsuki space probe, the only active mission studying Venus, has lost contact with JAXA due to stability control issues. Efforts are underway to reestablish communication, but if unsuccessful, it will end nearly a decade of valuable observations of the planet. This would leave a significant gap in Venus research until NASA's planned missions launch in 2029 and 2031.

"Japan's Akatsuki Probe, Humanity's Only Venus Mission, Falls Silent"

Japan's Akatsuki spacecraft, the only active mission studying Venus, has lost contact with Earth, jeopardizing ongoing Venus exploration. Launched in 2010, Akatsuki overcame initial setbacks to provide valuable data on Venus's atmosphere and climate. Efforts to re-establish communication have been unsuccessful, and JAXA is considering next steps as the spacecraft had already exceeded its designed lifespan.

"Earth Loses Contact with Sole Venus Probe Akatsuki"

Japan's space agency JAXA has lost contact with its Venus probe Akatsuki, which has been studying the planet's climate since successfully entering orbit in 2015 after an initial failure in 2010. Efforts are underway to reestablish communication, but the spacecraft's mission may be over. Despite this setback, Akatsuki has significantly contributed to our understanding of Venus, and new missions from various space agencies are planned for the near future.
