Update on Chang’e-4 plant experiments
Link here. It appears the plant experiment has now run its course, designed as it was to end before the arrival of the first lunar night.
The experiment’s chief designer, Xie Gengxin of Chongqing University, told Xinhua that life inside the canister would not survive the lander’s first lunar night, which started on Sunday. The moon’s nighttime period lasts for about two Earth weeks.
It also appears that though the plant experiment included potato, cotton, and oilseed rape, only the cotton seeds spouted. China has only released a limited amount of information about this research, so to get further details we will likely have to wait for the published papers.
Now available in hardback and paperback as well as ebook!
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.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.

S couple of typos in there Mr Zimmerman.
Seed sprouting is relatively trivial compared to normal growth for plants subjected to low gravity conditions. Sprouting depends on moisture and temperature for seeds biochemically ready to start growing. Gravity is the factor that orients the direction roots and stems point. I wondered how the specimens would be kept alive during the long lunar night. Now we know this experiment was the tiniest of baby steps.
Andrew_W: Fixed. Thank you!
As per The Martian does this mean China has colonized the moon?
Watney’s “In your face, Neil Armstrong” moment said that once you grow crops, you are a colonist. Unfortunately for China, these are not crops, just test plants. Otherwise we would have already colonized low Earth orbit.

Come to think of it, I recall that some astronauts on the ISS ate lettuce that they grew. Crops? ISS as colony?
One day we will colonize Mars
