Despite the impact, scientists believe that if anything survived the crash intact, it may well have been the tardigrades. The microscopic creatures were sandwiched between micron-thin sheets of nickel and suspended in epoxy, a resin-like preservative that acts like a jelly — potentially enough to cushion their landing.
Despite the lack of large marsquakes, the researchers were able to estimate how thick Mars’ crust is. They predict it has three layers—but possibly two—that are between 12.4 and 23 miles thick, reports Nature. Mars’ crust is considerably thinner than that of Earth, which can be up to 25 miles thick—and that’s surprising, reports Science.
Dropping a shoutout to all my followers, old and new. Thanks for reading!
I’m preparing this week’s installment of Bringer of Light (Chapter 3, Part 2), all the while scouring the web for science and tech news to share.
Anything you want to see shared (or want to share)? Comments on the story so far? Something you want to rant about? (No politics please! Waaay too much of that at home right now. I’d rather keep my head in the stars when possible…)
Bringer of Light: Chapter 3, Part 2 – dropping at 7 p.m. EDT October 31st. No Halloween theme, sorry (that’s a separate post 🎃).
The new research is especially topical given that NASA plans to land humans on the Moon in the 2020s and use lunar resources as part of its Artemis program, prompting thorny discussions about legal and ethical extraction of materials on the Moon.
The volcano is about the size of Arizona with a volume100 times larger than that of Mauna Loa’s,Earth’s largest volcano, NASA says. “In fact, the entire chain of Hawaiian islands (from Kauai to Hawaii) would fit inside Olympus Mons!”
Brighter than Jupiter this October! And the closest Mars will be until 2035.
“When you look at different parts of the electromagnetic spectrum, that area of space is very different from the blackness we perceive with our eyes,” says Michele Bannister, an astronomer at the University of Canterbury in Christchurch, New Zealand, who studies the outer reaches of the Solar System. “Magnetic fields are fighting and pushing and tied up with each other. The image you should have is like the plunge pool under Niagara Falls.”
“But decoding and storing memories raise a new set of ethical, moral and legal questions. For instance, who would own these memories after a person has died? Could the police obtain warrants to search through memories? Given that memory itself isn’t completely reliable, could memories be used in lawsuits? How could we ensure that unscrupulous professionals don’t sell or share them?”
Hm, I think I can see another direction this might eventually take…
OK, so I admit it — I’m way behind in finishing my SF novel, Bringer of Light (you can read the prologue here).
I had hoped to get the draft done by January, then work on edits in the spring and publish it in summer.
But a little COVID happened to the world, and believe it or not I got a little sidetracked by, uh, life. And a family history project about a love triangle (kind of).
(During our two-month quasi-lockdown-not-sure-what-this-is-stuck-home-with-two-kids thing, I did get pretty good at the Mars terraforming game. Highly recommended.)
So now I’m thinking, to kickstart my writing life back into action, why not post the chapters I have so far? There are about 35 of them, tend to be short, and since I’ve been struggling with the ending, might help generate some ideas for getting to the expected final scene.
I get the attraction of people like Steve Jobs and Elon Musk. They have big ideas. They’re enthusiastic, ecstatic, even. They’re great at simplifying difficult concepts and promoting tech to the lay person.
But they’re not creators. They’re “visionaries.”
Is that a bad thing? Of course not. I was in computer sales once. It was hard. Only the charismatic are good at it. But I didn’t have the knowledge and ability to make the products I was selling, let alone the power to innovate.
Sticking a chip in a person’s brain and sending thousands to the Moon or Mars sound cool. Possible, even.
But science isn’t sales. Someone might die.
We need visionaries, but scientists are more important. Maybe if they talked to each other…
