China to fly asteroid sample mission in ’24
The new colonial movement: Chinese scientists have revealed that China is now building an asteroid sample mission to launch in ’24 and grab samples in ’25 from the near Earth asteroid dubbed Kamoʻoalewa.
According to a correspondence in Nature Astronomy, there are two typical approaches to sampling asteroids like Kamoʻoalewa, namely anchor-and-attach and touch-and-go.
The former requires delicate and dangerous interactions with the planetary body but allows more controllable sampling and more chances for surface analysis. The latter, used by Hayabusa 2 and OSIRIS-Rex, is a quick interaction facilitated by advanced navigation, guidance and control and fine control of thrusters.
China’s mission will use both architectures in order to “guarantee that at least one works.” The paper states that there is “still no successful precedent for the anchor-and-attach architecture,” meaning a possible deep space first. A 2019 presentation reveals that China’s spacecraft will attempt to land on the asteroid using four robotic arms, with a drill on the end of each for anchoring.
The attempt to do both these approaches is audacious, especially because the evidence from both OSIRIS-REx and Hayabusa-2 is that it will be difficult to safely land and hold onto a rubble pile asteroid. The material is too loosely held together.
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

I’m trying to imagine how I would secure my car to a pile of gravel if I was parked on a hill and I had no functional brakes. I can really only think of a few ways to approach it and one would be a giant lasso. I think any attempt with harpoon would be iffy, you are just as likely to hit a rock dead on and watch your harpoon bounce off. Maybe a set of giant spindly legs like on long-leg spiders, then just use a gentle touch.
