From nothing to Mars in 6 years

December 20, 2022

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?

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…)

ispace is not “Japan” but “Japanese”

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…

US to report major fusion breakthrough

December 12, 2022
MThomas

The Financial Times reported Sunday that scientists in the California-based Lawrence Livermore National Laboratory (LLNL) had achieved a “net energy gain” from an experimental fusion reactor.
https://www.ndtv.com/world-news/us-to-announce-major-scientific-breakthrough-amid-nuclear-fusion-reports-3598437/amp/1

This is being spread across various websites. FT and Washington Post wrote the most details, but both are behind paywalls (boo) so I cited NDTV instead.

If…a BIG if…this report is true, it would still take a decade or more to commercialize fusion to the point where it would make even a dent in climate change.

But it would be a big first step.

A BIG if.

(FWIW, European scientists claimed this back in February …and in June… and again in September, and then it all fizzled out. So I’m not holding my breath on yet another politically charged, puff out our nationalist chest claim until I see scientific evidence that the reaction can be sustained and repeated elsewhere.)

Can you say “billlyons and billyons of dollars”?

Why do all the planets orbit the sun in the same direction?

December 11, 2022

Note: not to scale (duh). Thanks, Getty. Uh, is this really the best way to show the solar system? (There…are…NINE..planets!)

Think of pizza dough flattening into an enlarging disk as it’s tossed. Because the cloud had an initial rotation, this same direction of spin has persisted…
https://www.popularmechanics.com/space/solar-system/a39729213/why-do-all-the-planets-orbit-in-the-same-direction/

So basically the answer is simply that that’s the way they all started out.

Some moons, however, do have retrograde orbits. I.e., they orbit in the opposite direction around their respective planets. Some small asteroids and comets also have retrograde orbits due to their small mass being easily affected by larger cosmic objects.

But I bet now you’re all thinking of pizza… 🍕

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…)

Why Japan and JAXA are definitely NOT the future of space exploration

November 26, 2022

Falsified space research? No problem. The “apology bow” (sha zai, 謝罪) makes it all better.

There is a reason why Japan’s newest “micro” satellite spectacularly failed to do, well, anything.

The Japan version of NASA (Japan Aerospace Exploration Agency, called “JAXA” for some reason rather than “JAEA” — maybe the founder was a fan of X-Japan?) is riddled with incompetency and sycophancy.

Much like the rest of Japan’s government, one of the most corrupt of the world’s industrialized countries thanks to its strict “senpai-kohai” hierarchy where those at the top do no work and those at the bottom have no choice but to do what those at the top say – even if it’s illegal or immoral.

Volcanos, Venus, and Earth 🌋 Hellscape unveiled

November 25, 2022

A new study shows that massive volcanic eruptions over an extended period of time may be responsible for changing the planet into what it is today. If there was simple life on ancient Venus, volcanism was its doom. The study also shows how powerful volcanic activity has played a role in shaping Earth’s habitability and how Earth only narrowly avoided the same fate as Venus.
https://www.universetoday.com/158696/volcanoes-are-the-worst-theyve-caused-extinctions-on-earth-and-probably-killed-venus/#more-158696

Venus is hot enough to melt lead, which is why no spaceship has ever survived to land on the surface.

And, no, there is nothing alive floating around in its toxic atmosphere.

But this is a neat article. Three future missions are planned for Venus (two by NASA – VERITAS and DAVINCI – and one by ESA – EnVision, which sounds more like a song and dance competition than a scientific probe).

Venus or bust!

DART did it! 🎯

“For the first time ever, humanity has changed the orbit of a planetary body,” said NASA planetary science division director Lori Glaze.
https://www.sciencenews.org/article/dart-mission-deflected-asteroid-for-planetary-defense

A change of 32 minutes in orbit — but only 4% of the total orbital period. To deflect an asteroid away from Earth, it’d better be done several years in advance. 🌏

Still, it can be done. An amazing first.

Onward and upward, Excelsior!

Just passed 200 followers on WordPress. Thank you, everyone!

I know I should be posting a whole lot more often than I have. There are LOADS of new science articles and events happening recently, so I’ll see if I can get caught up over the next couple of weeks.

Plus a new chapter of Bringer of Light by the end of the week! I promise!

(And it would be VERY helpful if WordPress didn’t “refresh” while I was adding tags and categories to posts, and then hiding those tags and categories afterward so that I couldn’t update them…Sigh…what was wrong with the older version that worked just fine?)

We could live together / crystals on the Moon…

September 18, 2022

*Half of a dilithium crystal? (It’s a new type of crystal called “Chang’esite” (after the ancient Chinese moon goddess).*

I should be posting another chapter from Bringer of Light, but I don’t feel like writing that right now, what with a humongoid typhoon slowing churning its way here.

So here’s an article about what Chinese scientists found in Moon dirt.

Also H3. Yay. Let’s make fusion reactors and walk on the Moon together…
