Japan’s Hayabusa 2 spacecraft and its science team bid a bittersweet farewell to the asteroid Ryugu, 180 million miles from Earth, and began the months-long return trip to Earth with a precious set of samples.
“This is an emotional moment!” the team tweeted on Nov. 12.
“It’s sad to say goodbye to Ryugu,” project manager Yuichi Tsuda said at the Japan Aerospace Exploration Agency’s command center. “Literally it has been at the center of our lives over the past one and a half years.”
The farewell isn’t finished quite yet, however. Over the next few days, Hayabusa 2’s camera will capture pictures of the half-mile-wide asteroid as it recedes into the background of space. Then the probe’s field of view will turn back toward Earth for the return journey.
