Testing a flying taxi for Osaka 2025 Expo

March 15, 2023

An air taxi service set to feature at the 2025 World Exposition in Osaka was tested in Osaka Castle Park on Tuesday, in what the prefectural government says is the first time in the country one of the craft has been piloted from the cockpit.

The “taxi” they tested only fits one person. If the plan is to taxi visitors to the Expo back and forth between various artificial islands, I hope there are plans to test the actual three- to six-seaters.

And of course, there is always the “big challenges ahead are Japanese regulations and residents’ feelings” things. I wouldn’t be surprised if the first flying taxi to successfully taxi people around by air also becomes the first flying taxi to have a flying traffic accident.

(That’s what happened to Ohio City inventor James Lambert, who was testing an early gas-powered car when he hit a tree. Ireland claims to have an earlier accident, but it wasn’t a vehicle anything like a modern car.)

Another day, another rocket failure…

With just over a minute to go before liftoff, a California aerospace startup opted to stand down from launching the world’s first 3D-printed rocket on its inaugural test flight.

At least unlike the spectacular self-destruction of JAXA’s H3 this past Tuesday (Monday, Japan time), the team testing the California rocket wisely decided that it’s not a bright idea to stick a billion dollar satellite on an untested rocket. Repeatedly.

I’m beginning to feel that using 3D printed parts may not be the way to go with rocket engines…

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

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

“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.”

JAXA failure. Here we (don’t) go again.

At liftoff time, smoke was seen rising from the bottom of the rocket, indicating the ignition of the main engine. However, the rocket did not rise from the launchpad.

Not a great start to the year, JAXA. This, on top of the Episilon failure (zero, zero…DESTRUCT…zero…)

Shooting star over the English Channel

The agency earlier said the object was expected to “safely strike” the earth’s atmosphere near to the French city of Rouen.

https://www.bbc.com/news/uk-64621721

“Near to”? OK.

Anyway, “SAR2667” provided some cross-cultural entertainment for people living in England, France, Belgium, and the Netherlands. Lots of photos and videos online.

Interesting note from ESA: they were able to detect it and notify everyone exactly where and when it would disintegrate.

Since there are more than 30,000 of these things that orbit the Sun relatively close to Earth’s orbit, it’s a good thing we’re getting better at detecting them. Maybe we’d better up the ante on deflecting them

“Don’t worry,” they said, “the size of a truck,” they said…

An asteroid is on its way to Earth, but don’t worry – the end is here Not here. The asteroid, named 2023 BU, is about the size of a van and is expected to miss our planet during Thursday’s flyby. However, according to a NASA scientist, it will be “one of the closest approaches of a known near-Earth object ever recorded.”

https://newsbeezer.com/germanyeng/a-truck-sized-asteroid-will-come-extraordinarily-close-to-earth-tomorrow/

This thing is coming closer than even some satellites, but it’s still small enough for most of it to burn up in the atmosphere.

Most of it.

Yikes.

Bringer of Light, Chapter 38 (Part 1): United Mars Colonies — Cut the Tether

January 7, 2023

This installment is a bit longer than anticipated, so I will cut it into two parts. Metaphorically. Just like the Artemis crew will need to, following their agreement with the Mars colonies faction heads to train the afflicted settlers in controlling their odd new powers and sensations while assisting in distribution of temporary water and food supplies. Only Martin, the former Mars UN Overseer, who thinks he can manipulate the situation, is about to find out things are proceeding far faster than he planned. And Luna Base has a nasty surprise in store for Mars…

The storeroom chambers were nearly full by now. It had taken several days, but at last the food and water brought from Ceres had been stacked neatly, carefully portioned and labelled for each settler division. Orders were sent to each settler node requesting two or three representatives to bring their respective robotic platform dollies to the main supply chamber.

Cooper strolled casually along one earthen wall, rubbing a hand against the soil. He could feel the regolith composite materials, sense the minerals and hydrocarbon content. It would be so easy to extract and solidify what they needed, strengthen the structure. Or dig even deeper below the planet’s surface.

“Here,” Martin said, handing a pad to Cooper. “I’ve authorized the complete list of supplies brought by the Artemis. There’s my thumb verification, at the bottom.”

Cooper accepted the pad. He scrolled up to verify, nodding. “That should do it.”

“Now,” Martin said, addressing both Artemis crew members with him. “I’d like to find out what happened to my security chief, Hamels. She was outside the airlock when you dropped the ditrium on the ice cap.”

“First things first,” Enoch said. “We’d better make sure that the quantum teleportation nodes from Luna are severed.”

“Severed?”

“Yes. Completely.”

Martin turned pale. “That would seem a bit, er, final, wouldn’t it?”

Enoch grinned. “You bet. And necessary. Who knows what might come through the next time the UA turns the system on again?”

“Meaning?”

The geist spread his hands wide and made a booming sound, then laughed. The tall spacer slapped his crewmate on the shoulder, then both laughed hysterically for a moment. Martin stared at them. Cooper couldn’t help doubling over again, holding his stomach.

From nothing to Mars in 6 years

In 2020, the UAE’s space agency launched its first Mars mission, less than a decade after it was created. How did they manage it?

https://www.bbc.com/future/article/20221206-how-the-uae-got-a-spacecraft-to-mars-on-the-first-try

This is a great story about how true international cooperation rather than competition can result in scientific progress.

Thanks to their efforts, despite nearly being derailed thanks to the pandemic, we will soon have a complete picture of an entire year of Mars weather.

Not bad for a country whose space agency is so small “you could probably lose it in the car park of Nasa’s giant Johnson Space Centre in Houston.”

(Of course, the project’s findings may mean I have to rewrite some of my novel in progress, but why not? All in the name of science fiction…)

Neuroscience and the ethics of mind control

“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…)
