Humanity's last active mission at Venus is no more.

The Japanese Aerospace Exploration Agency (JAXA) declared its Akatsuki spacecraft dead on Tuesday (Oct. 28), more than a year after the Venus climate probe failed to respond to calls from mission control.

"This was a mission that changed our view of our Earth-sized neighbor, and laid the path for new discoveries about what it takes to become heaven or hell," JAXA officials stated of the mission, referring to the notoriously high-pressure and high-temperature surface of Venus in comparison to Earth.

JAXA noted that the Akatsuki mission produced 178 journal papers and counting, and that it tripled its 4.5-year design lifetime — even though the probe missed its first shot at orbiting Venus.

The $300 million spacecraft, also known as the Venus Climate Orbiter, launched in 2010 and experienced a failure of its main engine along the way, missing the chance for a crucial burn to enter orbit. Incredibly, however, the mission survived long enough for a second try at orbital insertion in 2015, when Akatsuki drew close to Venus after five years of orbiting the sun.

"With the main rocket engine damaged, the team were forced to get creative," JAXA wrote in the statement. "The spacecraft would have to attempt capture using the less powerful thrusters that were designed for the tasks of attitude control and fine adjustments. Orbit insertion had never previously been achieved with such a method, but exploration has always been about redefining the impossible."

Akatsuki not only made it but persisted in its exploration of Venus for nearly a decade.
