“Rock. Rock. Rock. Rock. Rock. Rock. METEORITE!”

March 7, 2023

The mysterious object’s lovely silver metallic hue stands out like a sore thumb in the surrounding, rust-colored landscape, a sulfate-bearing region of the Red Planet’s Mount Sharp.

Yes, they’re actually calling the meteorite fragment “Cacao.” Sigh.

Too bad Curiosity can’t take any samples. Perseverance can, but it’s too far away.

Curiosity has stumbled across several other such rocks previously, like “the Beast” and “Lebanon.” Sadly, none can be dated.

But the fact that there are so many of these impacted on the surface of Mars shows additional risks that any human mission might face…

The real danger of unregulated AI

February 27, 2023

“I’m less frightened by a Sydney that’s playing into my desire to cosplay a sci-fi story than a Bing that has access to reams of my personal data and is coolly trying to manipulate me on behalf of whichever advertiser has paid the parent company the most money.

“Nor is it just advertising worth worrying about. What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,” Gary Marcus, the A.I. researcher and critic, told me. “I think that’s already been a problem for society over the last, let’s say, decade. And I think it’s just going to get worse and worse.”

The 2022 Year of Space Exploration

January 2, 2023
MThomas

Lots and lots and lots of space stories occurred in 2022.

From DART to Landsat, Sagittarius A* black hole to CAPSTONE, the Korean Pathfinder to SpaceX, and to the ISS, Moon, and Mars, here’s a summary of major space exploration projects last year.

Looking forward to 2023 and beyond!

What does a dust devil on Mars sound like?

December 21, 2022
MThomas

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.

https://www.nbcnews.com/science/science-news/mars-rover-captures-first-sound-dust-devil-red-planet-rcna61642

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…

ChatGPT: Is this really the “death of the essay”?

December 17, 2022
MThomas

I’ve been testing ChatGPT over the last couple of days. (If you don’t know what this chatbot is, here’s a good NYT article about ChatGPT and others currently in development.)

The avowed purpose of ChatGPT is to create an AI that can create believable dialogues. It does this by scouring the web for data it uses to respond to simple prompts.

By “simple,” I mean sometimes “horribly complicated,” of course. And sometimes a little ridiculous.

Somehow, I doubt that people in the US said “livin’ the dream” in the ’50s…

As has been pointed out, chatbots only generate texts based on what they have been fed, i.e., “garbage in / garbage out.” So if you push the programs hard enough, they will generate racist, sexist, homophobic etc awful stuff — because unfortunately that kind of sick and twisted garbage is still out there, somewhere online in a troll’s paradise.

So far, I have asked the program to:

  1. Write a haiku about winter without using the word “winter”
  2. Write a limerick about an Irish baseball player
  3. Write a dialogue between God and Nietzsche (I just had to…)
  4. Imagine what Jean-Paul Sartre and Immanuel Kant would say to each other (see above) but using US ’50 slang
  5. Have Thomas Aquinas and John Locke argue about the existence of God (that one was fun)
  6. Write a 300 word cause-effect essay about climate change
  7. Write a 300 word compare and contrast essay about the US and Japan
  8. Write a 1000 word short science fiction story based on Mars
  9. Write a 1500 word short science fiction about robots in the style of Philip K Dick

OK, and the verdict is:

ispace is not “Japan” but “Japanese”

December 16, 2022
MThomas

Mission success would also be a milestone in space cooperation between Japan and the United States…

https://www.yahoo.com/news/japans-ispace-readies-delayed-launch-220204283.html

OK, wait…

A Japanese start-up (I.e., a small private company)…

using a SpaceX rocket (I.e., a private company owned by the world’s wealthiest pri…er, person)…

sends up a small craft made in Germany… 🇩🇪

along with the Rashid rover (made by the UAE)…

and “a two-wheeled, baseball-sized device from Japan’s JAXA space agency”…

and somehow this is cooperation between the US and Japan versus China and Russia?

I’m not seeing it. The project may have used a NASA launchpad, but the people are charge (and the ones paying for it) are not part of any national government.

And I have a feeling this is the wave of the future. More and more private companies will get involved in space projects as they realize that they can thus ignore politics and aim at profits.

I, for one, welcome our future corporate overlords…

Neuroscience and the ethics of mind control

December 5, 2022
MThomas

“Embedding a similar type of computer in a soldier’s brain could suppress their fear and anxiety, allowing them to carry out combat missions more efficiently.”

https://theconversation.com/amp/brain-computer-interfaces-could-allow-soldiers-to-control-weapons-with-their-thoughts-and-turn-off-their-fear-but-the-ethics-of-neurotechnology-lags-behind-the-science-194017

Sounds like science fiction, but it’s pretty close to reality. BCI (brain computer interface) is being tested in patients who lack muscle control but imagine if this tech gets weaponized (and what hasn’t been, eventually).

But what if BCI were used to suppress emotions in a healthy brain? Or used to implant thoughts? Or worse?

“…if a BCI tampers with how the world seems to a user, they might not be able to distinguish their own thoughts or emotions from altered versions of themselves…”

(same website as above…note that the PC version of WordPress does not do “quotations” correctly any more…)

PKD fans will instantly recognize this.

Androids don’t just dream of electric sheep. 🐑

(Fans of Ghost in the Shell and more importantly its movie sequel Innocence should also recognize the potential hacking danger…imagine if the government could control our emotions, thoughts, and memories…)

Attack of the Killer Drones — Non-fiction not fiction?

July 26, 2022
MThomas

These aren’t the drones that deliver your online order. Loaded with cameras, sensors, and explosives, their mission is to drive themselves to a target with an algorithm in the driver’s seat. They destroy themselves along with the target, leaving behind just a pile of electronic detritus.

https://m.dw.com/en/killer-robots-will-they-be-banned/a-62587436

Oh, joy. I can’t wait to see what happens when we program 3D printers to churn them out.

Or just simply make them self-replicating. What could possibly go wrong?

The University of Tokyo just covered a robot finger with real skin. The jokes write themselves…

June 20, 2022
MThomas

Skin is also just the first step in combining organic matter with machines, and opens the door for incorporating nerves and sensory organs such as olfactory receptors which can detect scents.

https://soranews24.com/2022/06/16/robot-finger-covered-in-living-skin-developed-by-university-of-tokyo/

The original report was published online by the U of Tokyo before it was covered last week by several online sources, including WebMD, the Independent, France 24, and ABC7, but the Sora News is the only one to post Japanese reader comments about, well, what fingers can do. Ahem.

The final quote of the researchers was posted on WebMD as:

“We believe this is a great step toward a new biohybrid robot with the superior functions of living organisms.”

Eek. Maybe might wanna rethink this…

Robot performs surgery — on pig intestines

January 27, 2022
MThomas

They slice. They dice. They perform complicated microsurgery without the aid of doctors…

US researchers say a robot has successfully performed keyhole surgery on pigs all on its own – without the guiding hand of a human. Furthermore, they add, the robot surgeon produced “significantly better” results than humans.

https://www.theguardian.com/technology/2022/jan/26/robot-successfully-performs-keyhole-surgery-on-pigs-without-human-help

OK, that’s neat. But.

Hands up, who wants to have their intestines spliced together by the Terminator v. 1.0?
