Yutu-2 travels almost 300 meters on ninth lunar day
According to a story today in official Chinese state-run media, Yutu-2 traveled another 284.99 meters during its ninth lunar day on the surface of the Moon, and has now been placed in hibernation in order to survive the long lunar night.
The story provides no further information, including saying nothing about the strange and unusual material the rover supposedly spotted during this time period.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

That comes to three meters an hour. I wonder why it is so slow.
For the same reason Curiosity is, I suppose – limited or no ability to conduct autonomous driving combined with considerable caution on the part of its handlers. Zipping around could tip it over or put it into some small ground declivity not easily spotted if moving faster. The latter sort of mishap could trap it.
It could be the gearing is involved. For a given motor (and the size is limited by everything else the rover needs, you want more instruments, maybe motor and battery size need to go down), the lower the gearing, the greater the torque, but the lower the speed. You’re not trying to set speed records here and the more torque you have, the steeper the slope you can ascend and, perhaps, the easier to get you out of awkward situations.
Hmm. Because our robotic rovers do not travel so fast, maybe we would get more exploration for our buck if we had humans doing the exploration. They move much faster, make their own decisions on the spot, but they cost a bit more to get there and back again.
