Japan lands on the Moon — for just a few hours

January 20, 2024

A Japanese robot has successfully touched down on the Moon but problems with its solar power system mean the mission may live for just a few hours.

The Smart Lander for Investigating Moon (Slim) put itself gently on the lunar surface near an equatorial crater.

Or SLIM, if you want to actually write acronyms properly (snark).

Also, it’s JAXA, not Jaxa. And NASA and ESA, not Nasa and Esa. But I digress.

Anyways, kudos but too bad yet another space mission failed. At this point I’m wondering how on Earth NASA managed to land people on the Moon so successfully in the 1960s and 1970s without killing half of them in the process. We can barely manage to get a tiny robot rover the size of a marble to land (see the link above for the picture of the “hopper” and “shape shifting” ball…curious about the “shape shifting” bit…)

Webb reveals rocky planets can form in extreme environments

December 3, 2023

This is an artist’s impression of a young star surrounded by a protoplanetary disc in which planets are forming. An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to provide the first observation of water and other molecules in the inner, rocky-planet-forming regions of a disc in one of the most extreme environments in our galaxy. These results suggest that the conditions for rocky-planet  formation, typically found in the discs of low-mass star-forming regions, can also occur in massive-star-forming regions and possibly a broader range of environments.

Because of its location near several massive stars in NGC6357, scientists expect XUE 1 to have been constantly exposed to a high ultraviolet radiation field throughout its life. However, in this extreme environment the team still detected a range of molecules that are the building blocks of rocky planets.

In essence, this expands the possibility of finding many more rocky planets than were previous thought to be exist.

Lots of “gas giants” and a few “super Earths” have been found so far. But Webb is just getting started…

When AI becomes actual AI…

October 26, 2023

We compared current scientific theories of what makes humans conscious to compile a list of “indicator properties” that could then be applied to AI systems. 

We don’t think systems that possess the indicator properties are definitely conscious, but the more indicators, the more seriously we should take claims of AI consciousness. 

https://theconversation.com/why-chatgpt-isnt-conscious-but-future-ai-systems-might-be-212860

Last year, an engineer for Google who was working on what was then called “LaMDA” (later released as “Bard”) claimed that the software had achieved consciousness. He claimed it was like a small child and he could “talk” with it.

He was fired.

Bard, ChatGPT, Baidu, and so forth are advanced chatbots built on what’s called “Large Language Models” (LLM) and can generate text in an instant.

But the programs are not AI, strictly speaking. They have no sentience.

First-look at the Dust of Bennu

October 12, 2023
MThomas

Carbon accounted for almost five percent of the sample’s total weight, and was present in both organic and mineral form, while the water was locked inside the crystal structure of clay minerals, he said.

Scientists believe the reason Earth has oceans, lakes and rivers is because it was hit with water-carrying asteroids 4 to 4.5 billion years ago, making it a habitable planet.

https://www.sciencealert.com/first-look-at-pristine-asteroid-dust-reveals-abundance-of-water-and-carbon

We have ample evidence now that all water on Earth was brought during the “Late Heavy Bombardment” period (4~4.5 billion years ago). Imagine how many rocks it took to get enough water (estimates anywhere between 20 and 200 million years of asteroid after asteroid slamming into the Earth).

And the only reason life exists on Earth is that there is enough iron and nickel in the Earth’s core to generate a magnetic field to prevent solar radiation from ripping off the atmosphere. Which is likely what happened to Mars.

(Alright, alright, technically electrical currents running through the liquid iron outer core as well as in the crust and ionosphere also contribute to the magnetic field. Go check out this horribly complicated explanation if you like.)

Note that this is the third time to get asteroid dust to examine. JAXA has managed to do this twice now. But Hayabusa-2 only got about 5 grams. The OSIRIS-REx project got about 250 grams (1/2 lb). Lots more = lots more to save for future researchers who will have developed even more sophisticated analysis methods.

Now lets get some PEOPLE on those things and start mining and living in space, already!

AI and the future of warfare (as predicted)

September 23, 2023
MThomas

Both Russian and Ukrainian forces are integrating traditional weapons with AI, satellite imaging and communications, as well as smart and loitering munitions, according to a May report from the Special Competitive Studies Project, a non-partisan U.S. panel of experts. The battlefield is now a patchwork of deep trenches and bunkers where troops have been “forced to go underground or huddle in cellars to survive,” the report said.

https://www.reuters.com/technology/human-machine-teams-driven-by-ai-are-about-reshape-warfare-2023-09-08/

I found it interesting that many people online were commenting about Iain M Bank’s take on AI (for an in-depth analysis of his Culture series check this out on Blood Knife) and how he “predicted” all this.

Uh. You know, I’m not sure whether Banks wrote much about integrating traditional weapons with AI (since I haven’t read his series). But I do know that PK Dick wrote a short story called “Second Variety” about trench warfare and AI robots making more versions of themselves and taking over the world.

He wrote it in 1953.

(You can read it at Project Gutenberg.)

That is waaay before the Culture series.

Sigh. Read the classics, guys.

O Isis OSIRIS-REx!

September 16, 2023
MThomas

Currently, OSIRIS-REx is located at a distance of 7 million km from our planet. On September 24, OSIRIS-REx will drop a capsule with samples of asteroid matter, after which it will enter the earth’s atmosphere and land on the territory of the Utah Test and Training Range.

https://universemagazine.com/en/osiris-rex-is-on-a-course-for-earth/

The tiny spacecraft launched back in 2016 and reached the asteroid Bennu in 2021.

One main reason for this mission is to find out what Bennu is made of. After the asteroid spewed out tiny “micromoons,” OSIRIS-REx successfully collected a tiny soil sample. By “tiny,” I mean less than 50 to 60 grams. And it couldn’t actually land, since the asteroid is too small to have enough gravity to support the spacecraft.

Now we have less than two weeks to find out what’s in the soil — assuming the capsule is retrieved without incident. And then OSIRIS-REx will head back out to visit yet another asteroid (Apophis) in 2029.

Yes, that famous “planet-killer” the media screamed about a few years ago as “the most dangerous asteroid in the world.” (uh. “in the world”?) It will “only” approach within 38,000 km in April 2029, but could possibly collide in 2036.

No problem.

Quantum Consciousness: Incredulous or Real?

September 12, 2023
MThomas

It’s easy to see why fractals have been used to explain the complexity of human consciousness. Because they’re infinitely intricate, allowing complexity to emerge from simple repeated patterns, they could be the structures that support the mysterious depths of our minds.

But if this is the case, it could only be happening on the quantum level, with tiny particles moving in fractal patterns within the brain’s neurons. That’s why Penrose and Hameroff’s proposal is called a theory of “quantum consciousness”.

https://www.inverse.com/science/consciousness-and-quantum-physics

Quantum computers can only operate at extreme low temperatures (-272C, or -460F, which is basically colder than even the average temperature of outer space, so cold that we made up a new temperature scale called Kelvin to measure it — and no, the “Kelvin timeline” of Star Trek was not named after the temperature but after J J Abram’s grandfather).

So anyway, how is it possible that human consciousness can be considered “quantum” if we need (quite obviously) a much higher temperature to survive? (Making us controlled by classical physics and not quantum physics.)

Our brains are composed of cells called neurons, and their combined activity is believed to generate consciousness. Each neuron contains microtubules, which transport substances to different parts of the cell. The Penrose-Hameroff theory of quantum consciousness argues that microtubules are structured in a fractal pattern which would enable quantum processes to occur.

Scientists have measured electron wave functions (their quantum state) by injecting photons into two types of fractal structures, one triangular and one square-shaped (like the Sierpinski carpet pictured above). The next step would be to take quantum measurements from the brain’s microtubules.

Hmm. I think I’ve seen a shape similar to the Sierinski carpet somewhere before…

“Female” robots and other bias

September 6, 2023
MThomas

When we give AI a humanoid form, we typically choose the robot to have feminine characteristics. Are we playing on stereotypes?

https://www.bbc.com/future/article/20230804-is-there-a-sinister-side-to-the-rise-of-female-robots

Isn’t it blindingly obvious?

All artificial intelligence, all robots and Chatbots and everything else electronically-programmed by a human being, will inevitably have human bias.

Even women prefer women’s voices to men’s when it comes to customer service.

On the other hand, women are also historically relegated to work with lower pay, lower status, kept out of positions of power — subject to the “male gaze.”

Now, we have AI that can be treated as sex objects. Even “married.”

So it is all “sinister,” as BBC asks?

Creepy, maybe. Sad, perhaps. Entirely predictable, definitely.

As we continue to lead more and more isolated individual lives, cut off from human contact and left unable to socialize, the rise of the “AI companion” seems inevitable…

Gateway not to be used until Artemis 4

September 4, 2023
MThomas

ESA image. Gateway is planned to be much smaller and more cramped than ISS (about 1/6 the size).

NASA and its international partners see Gateway as a key platform to support the agency’s Artemis moon program and to build the technology required for future deep-space missions. Although the first elements of the small space station are expected to launch before the Artemis 3 mission lifts off in 2025 or 2026, NASA previously said that those astronauts will not use Gateway to “make that mission have a higher probability of success.”

https://www.space.com/artemis-4-first-astronauts-visit-gateway-moon-space-station

While it’s a good idea to see some planning for this, I think maybe NASA should focus on getting Artemis 1 to work properly before they go on about Artemis 3 and 4.

Taking advantage of Gateway’s orbit far away from Earth’s protective magnetic field, three instruments will study risks due to radiation from the sun and from cosmic rays. Scientists hope this knowledge can help inform future long-term missions to the moon and Mars

Since Gateway will orbit the Moon and not the Earth, the biggest problem will be preventing astronauts (and instruments!) from getting fried by solar radiation. Scientists need to come up with materials to shield people on Gateway and the Moon, or else we’re going nowhere…

(That said, regolith – soil, basically – has already been proposed and even tested: Llamas et al. (2022). “Effectiveness of Martian regolith as a radiation shield,” Planetary and Space Science, 218, 105517 https://www.sciencedirect.com/science/article/abs/pii/S0032063322001039)

Dear Diary – January 24, 1998

For all these technological “advances,” we are no better than the ancients. We are still prisoners to our emotions — or to the biological impulses of electricity and hormones whose results we deem emotive.
