For many reasons, mostly political but partly ethical, I do not use Google, Facebook, Twitter. They practice corrupt business policies, while targeting conservative websites for censoring, facts repeatedly confirmed by news stories and by my sense that Facebook has taken action to prevent my readers from recommending Behind the Black to their friends.
 
Thus, I must have your direct support to keep this webpage alive. Not only does the money pay the bills, it gives me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.

After spending two weeks testing its main ion engines just beyond the gravitational sphere of influence of the asteroid Ryugu, Japanese engineers today initiated full engine operation, beginning the spacecraft’s journey back to Earth.

Hayabusa-2 is expected to return to Earth space in December 2020, where it will release a small capsule containing the two samples it obtained of Ryugu will be released to land on Earth and be recovered. At that point, if Hayabusa-2 is still in good condition it will be available to send to other locations in the solar system.

    A *very* good achievement for that team, and a good growth of multi-object explorations as a norm. I long for the next step, when a probe collects multiple samples from multiple objects swinging through the Solar System, to deliver them finally at an Earth-Moon Libration Point-1 station for analysis, as a group. Then, heading back out to the Belt, for even more.

    This craft has proved to be rather remarkable in its accomplishments.

    Let’s hope it has an easier time getting home than the first Hayabusa.
