Japan’s Venus Climate Orbiter Akatsuki was launched on May 21, 2010, and started its active mission in 2015 after an initial orbital insertion failure. Since that time, Akatsuki has continuously observed Venus from orbit until issues began to crop up in 2024 when contact was lost in April of that year due to attitude control issues. Japan’s space agency, JAXA, has now announced that the mission has officially ended on September 18, 2025, after a period of trying to coax the spacecraft back into some level of functionality again.
