China announces plans for asteroid/comet sample return mission


Readers!
 
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.

The new colonial movement: China today announced plans to fly an ambitious mission to both an asteroid and comet, which would also bring back a sample from the asteroid.

The current plan, which is still under discussion, calls for a probe to visit and collect samples from the small near-Earth asteroid 2016 HO3 (also known as Kamo’oalewa). “Then, the probe will fly back to the proximity of Earth, and a return capsule will be released to bring the samples back to Earth,” Xinhua reported today (April 18), citing a China National Space Administration official. “After that, the probe will continue its journey. With the assistance of the gravity of Earth and Mars, it will finally arrive at the main asteroid belt and orbit the Comet 133P to explore it.”

Both objects are unusual. The asteroid is in a strange solar orbit that almost makes it a moon of the Earth, while the comet appears to be a main-belt asteroid with comet-like activity.

The mission is not finalized yet, so expect some revisions.
