Are you sitting down for this? Well, you’re not really. Your butt isn’t actually touching the chair you’re sitting on. Since the meat of your atoms is nestled away in nuclei, when you ‘touch’ someone (or something), you aren’t actually feeling their atoms.
Hi, everyone. I guess I should have planned a little better — should have written a “new year’s post” and then saved it before the holiday season began, scheduled the post, and then enjoyed overeating, overdrinking, and sleeping in.
If you find a big rock in your backyard, and you can’tbreak it open with normal tools, guess what?
The researchers argue that the Maryborough meteorite is much rarer than gold. It’s one of only 17 meteorites ever recorded in the Australian state of Victoria, and it’s the second largest chondritic mass, after a huge 55-kilogram specimen identified in 2003.
This next bit is more interesting to me:
“Other rare meteorites contain organic molecules such as amino acids; the building blocks of life.”
Future moon settlers might benefit from oxygen extraction from lunar regolith as it can be used to create breathable air as well as a source for fuel. In addition, the newly found extraction method might also be useful for Mars colonization.
Regolith covers the Moon and Mars (and presumably many other potentially habitable rocky bodies).
Of course, the composition of regolith on the Moon differs from that of Mars.
But if the new method can extract sufficient quantities of both oxygen and hydrogen, there should be ample amounts for both human usage and rocket fuel.
(Yawn.) “Dry” science? Sure. But think of the (fictional) possibilities!
On this day, June 10th, what would have been my mother’s 69th birthday had she not passed away suddenly last October, I am conflicted.
Do I have the right to write about family history yet again?
And yet without the past, it’s difficult to write about the future. They are connected, by both visible and invisible lines, threads of beliefs and behaviors, attitudes and antagonisms, odd coincidences and strangely fortunate happenings. Particularly in my family. Continue Reading
