My op-ed on one-way trips to the Moon is up at Space News.

Solar Activity
Are we heading for a Grand Minimum?
If so, it will put to the test the CO2 climate thesis.
Asteroidal Resources
Just as when you’re pulling nickel out of the ground in Sudbury, when you use ocean water you’re mining asteroids. As I noted in my latest essay, the more we learn about the solar system, the more we discover that, as opposed to being what we long thought was “the water planet,” earth is a comparative desert. The water is mostly extraterrestrial.
To expand on Krafft Ehricke’s famous statement, if God had wanted us to become space faring, he’d have given us a moon. With water on it.
Shackleton
Bezos is hinting that at next month’s satellite conference, he may announce an expedition to the lunar south pole.
A Space Resources Institute
There is a bipartisan bill from two Colorado congressmen to establish one.
I heard about this from George Sowers when I stopped by to visit him in Golden a couple weeks ago. Presumably, their goal is to put it in the Front Range, and probably affiliate it with the School of Mines, which currently has the only graduate program in this discipline.
SLS And Moon In 2024
Methane On Mars
I suppose it’s possible that this is an April Fools post, but I don’t think Leonard would do that.
Blue Origin
…has been working on previously undisclosed Space Act Agreements with NASA on a lunar lander. That would seem to be part of the puzzle of what’s been happening over the past several days.
The Younger Dryas
It was apparently much worse than we thought:
As Kennett noted in a recent article in The Current (a university press maintained by UCSB), the crater would have led to widespread destruction, characterized by biomass burning, megafaunal extinctions and global cooling. “It’s much more extreme than I ever thought when I started this work,” he said. “The more work that has been done, the more extreme it seems.”
The discovery was made possible by a Chilean group of scientists who were studying sediment layers at the well-know Quaternary paleontological and archaeological site, known as Pilauco Bajo. Years ago, these scientists recognized changes in the sediment record that were associated with the YDB impact event.These included a “black mat” layer that coincides with the disappearance of South American megafauna fossils and human artifacts dated to the Pleistocene (12,800 years ago), indicating a severe shift in the climate. This was a major find since the vast majority of evidence for the YDB Impact has been found in the northern hemisphere.
Imagine that happening today. And here we’re obsessing over two degrees Celsius.
Better get moving on that vital SLS, so we can protect ourselves. #NotReally
Cave Systems On Mars
Bob Zimmerman thinks that this is very significant to settling the Red Planet.
