What does a dust devil on Mars sound like?

It was “definitely luck” that the dust devil appeared when it did, said the study’s lead author, who estimates there was just a 1-in-200 chance of capturing the audio.

Perseverance has been on Mars for almost two years now, and already recorded wind on Mars for the first time in February 2021.

This dust devil was recorded in late September 2021 (wonder why only now it’s being revealed?). The dust devil was “average size,” which is described as about 400 feet / 122 meters tall and 80 feet / 24 meters wide, traveling at 16 feet / 5 meters per second (≈ 11 mph / 18 mph).

UPDATE. NBC incorrectly reported in the above linked article that the dust devil was recorded by Perseverance. It was actually recorded by InSight, which has just fallen silent after four years of operation. Sigh. I should get science news directly from the source and not from unreliable “news” sites.

There are a lot of dust devils on Mars. A whole lot. Any settlement would have to be extremely prepared to deal with dust all the time, everywhere. If it ever got into equipment that regulated, say, breathable air inside habitats…

Trace Gas Orbiter finds traces of hydrogen underground in the Valles Marineris

The original article title?

“Astronomers Detect Secret Water Reserves in The Largest Canyon in The Solar System”

Science isn’t quite as catchy. The hydrogen may indicate water in the form of permafrost 3 feet and more under the surface.

The high-hydrogen region is about the size of the Netherlands, and overlaps with Candor Chasma, one of the largest canyons in the Valles Marineris system.

Looks like there may be some competition for who gets to land near here first…

Tales of a 6th-Grade Nothing (Apologies to Judy Blume)

November 26, 2021
MThomas

I started writing stories when I was in 5th grade. Our teacher gave us a list of vocabulary each week — about 10 to 12 words, I think — and said we had two choices: 1) write down all their definitions along with a sample sentence, or 2) work them into a short story to show that we understood the meaning of the words.

I chose the 2nd option. In fact, I was the only one who did out of a class of about 25.

The thing is, the teacher wanted us to read them at the front of the room.

Man, that was not something I was looking forward to. But somehow I managed.

I wrote nothing but detective stories, all in the first person. At some point, I borrowed my mother’s old manual typewriter (originally my grandfather’s, from the 1950s) and typed them all out. I still have most of them.

But my peak as an elementary school age creative writer came part-way 6th grade, when I attempted to write my first horror story.

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 🎃).

All My Love, Johnny – a true WWII love triangle in my family’s history

VMailJuly9? I should be finishing the SF novel I’ve been working on (and off) for the better part of four years now. Instead, I’ve found myself obsessed with letters recently found in my dearly departed mother‘s possessions…letters written from my grandmother’s first husband, John Hart, while he was in the US Army in the 1940s.

He died. This ain’t no story of heroic sacrifice or rah-rah patriotism. This is reality. Continue Reading

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.

Nobody has ever really touched anything in their lives.

Sleep tight…

(Not exactly a new article, but still interesting; and, yes, I might be using this to justify an awful lot of my soon-to-be-beta-read new novel 😉

Your Star Wars: Rise of Skywalker Reviews All Miss The Point

January 7, 2020
MThomas

Okay, so I figured that I would never do this.

I mean, write a Star Wars movie review? When so many have already been there, done that, loved it/hated on it/debated it? When I already did it (ah, twenty years ago, but still…)

But, then again, why not?

Especially when so many have gotten it so wrong… Continue Reading

Happy (Belated!) New Year’s 2020!

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.

Except of course that’s not what actually happened. Continue Reading

What’s more valuable than gold? This rock

December 27, 2019
MThomas

If you find a big rock in your backyard, and you can’t break 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.”

Hmmm… 🤔 Sounds like a storyline…
