Crap, I did it again

Man, I did it again.

I forgot to post the next chapter of Bringer of Light.

Also the next one after that. And the one after that.

It’s been a very tiring summer so far.

(For starters, we STILL don’t have enough Pfizer or Moderna vaccines, doses are get wasted left and right as the elderly randomly cancel reservations and the bureaucratic pinheads in charge refuse to give them to others, and several students at my school went out drinking and guess what happened…)

I haven’t even posted any science news lately.

But I promise that I’ll make up for it. Soon.

In the meantime, here’s a neat little article about some wild theories of the universe, starting with the Brane Universe and the Big Splat.

Yeah. I thought you might like that one.

Destination: Red Planet

Like other nations, China “regards Mars exploration as the preferred destination for deep space exploration,” Wang said.

https://abcnews.go.com/amp/Technology/china-unveils-ambitious-roadmap-human-mars-exploration/

China’s plan calls for setting up a permanently occupied base and a fleet of interplanetary craft. Probably it’s a good idea to first see whether it can meet its goal of landing people on Mars in 2033.

Of course, China is “willing to join hands with our counterparts and partners all over the world,” but it’s unlikely NASA, JAXA, ESA, and the UAE and other countries not named Russia will “cooperate.”

The next space race is here. Just wait until multinats actually decide asteroid mining is worth the risk and expense.

Ion engines are no longer sci-fi

The inclusion of an ion propulsion system in a long-running, Earth-orbiting space station will give researchers a chance to test out the tech while astronauts are still close to home — and if it works as hoped, it could one day ferry explorers to Mars and even more distant destinations.

https://www.freethink.com/articles/ion-propulsion

That’s a big “if.”

Another is what the price will be, since no doubt this neat new tech won’t easily be shared among nation-states.

Just yesterday Chinese astronauts entered their new space station for the first time. They weren’t allowed into the ISS. Now they don’t need the ISS.

The old rivalries will follow humanity into space…but for how long will the rivalries remain…

Squids…In…Space….!

OK, yeah, squid doesn’t have a plural, but come on, can’t you just hear “Miss Squiddy”? 🦑 (Reference lost on younger viewers.)

The 128 baby bobtail squid will be used as part of research into the effects of spaceflight on beneficial interactions between microbes and animals.

https://www.bbc.com/news/science-environment-57339989

So why use squid instead of dogs, chimps, or other mammals?

The squid have an immune system which is similar to that of humans.

Ah.

And their distinct lack of a spine makes them similar to most politicians, too. Very helpful for finding out what might happen if we decide to…

Nah.

Warp drives, wormholes, and FTL: oh, my

This is a neat summary of the current state of faster-than-light (FTL) theories. (From April 27, 2021).

As the author concludes in the words of Captain Picard, “Things are only impossible until they are not.”

China doesn’t care about the rest of the world — except when the rest of the world criticizes it

“When they did that design, they should have stopped and thought, ‘you know, that’s going to leave a big chunk of debris in orbit, we should change the design of the engine’,” McDowell says. “But they didn’t. This is real negligence.”

https://www.inverse.com/science/long-march-5b-uncontrolled-reentry

Four years ago, China’s first space station landed in the Pacific Ocean between Australia and Chile, after an uncontrolled reentry. China didn’t care.

Last year, pieces from a Long March 5B rocket landed in Cote d’Ivoire. They damaged buildings in two villages. China didn’t care.

This launch of the same rocket design could land anywhere from New York to New Zealand, covering a wide range of habitation. China doesn’t care.

On the other hand, once somebody in their government reads about the criticism by the scientific community, they’ll petulantly whine that this often happened in the 1960s, so that makes it OK for them to ignore rocket safety designs known for the past 30 years.

Maybe it’s technology they haven’t yet stolen from other countries.

As the self-acknowledged center of the known universe, the Middle Kingdom only cares what others think of it. Like a spoiled child that thinks it knows everything but fears it does not, China only reacts to its own mistakes by lashing out at others and disclaiming responsibility.

If you want to be respected as a superpower, you need to learn how to respect other countries and stop dumping your trash on them. Respect is not given, it is earned. China has done little to earn any respect by the scientific community.

X-Rays from Uranus!

Two-ringed and sideways gas giant

The gag practically writes itself…

…but seriously, this is neat. One source of the X-Rays is the Sun (it also bounces off of Jupiter and Saturn). But there may be yet another source…perhaps the rings of Uranus or the planet itself.

And no, it’s not really pink. That’s just a Chandra X-ray image.

Shame, really.

“Potentially hazardous asteroid” approaching Earth

This is how I’ll get a photo of 2001 F032 for its next pass in 2052.

Hazardous asteroid!? Call out Bruce Willis!

No worries. “Close to Earth” in this is 1.25 million miles. But it’s a great chance to find out more about the early solar system.

Bringer of Light, Chapter 15: The Sagittarius

February 27, 2021
MThomas

When we last left Gennaji, his ship was just about to fire or be fired upon. Somewhere near Encheladus…

Gennaji looked over at his crew at the rocket launcher. Karel and Andrzej both seemed tense.

No, he silently corrected himself, he was the one feeling tense. They looked…blank. Waiting. 

He shook his head.

“Ory, are they together or separate?”

“Looks like they plan to split up, heading around Encephalus. Opposite sides. Not quite in orbit yet.”

Gennaji cursed. Naturally. That’s what he would have done.

“Thrusters. Solid fuel only. Aim us at the Corvus. Shield us.”

“Aye, sir.”

He nodded at Karel and Andrzej. They strapped themselves down to the floor like cargo boxes, clamping suspender-like tethers wrapped around their waists to metal rings in the floor. Hurriedly he did the same, locking himself in front of the railgun console.

The Sagittarius began to peal starboard.

Starboard, he thought. Antiquated nautical term. Everything is starboard in space.

He shifted his weight and checked the railgun. All readings normal.

“Ory, position?”

“Corvus is closing…they’re firing!”

Firing?! Gennaji gritted his teeth. Hamno, the Corvus captain was insane, firing laser cannon from that distance. “Ory, evasive!”

The Sagittarius shuddered again, violently. His knee buckled and he slammed his right hip against a side wall. Shit, that hurts, he thought, refusing to cry out.

Karel apparently had no such compunction, judging by the sudden yelp. Gennaji glanced over. The big helmsman had fallen down sideways on one shoulder and was groggily getting to his knees. Andrzej seemed to have already crouched in anticipation and bounced up.

The tether was merely a brace after all, Gennaji thought. He grabbed the console corner and checked the readings again.

“Ory.”

“Captain, the shot missed by a wide margin. Looks like they forgot to compensate for the gravity well effect.”

Gennaji grinned. He figured that old hunter trick would work on a young crew like the Corvus. Now they had to wait to recharge.

“Range?”

“In range now.”

“Perfect. Ory, manuever us so we can get a good angle from the cargo hold.”

“Aye, sir.”

Gennaji felt the Sagittarius shudder as the thrusters moved them into position. He checked the console again before giving the order.

“Set.”

Karel depressed a switch. The sound echoed through the cargo hold.

“Fire.”

Andrzej yanked down with both hands on the firing lever. The rocket made a little popping noise as the railgun launched it through the port into space. Like a champagne bottle, Gennaji thought.

But with much more pop.

“Ory, get us away as fast as you can. Hard right.”

“Aye. The other ship is coming into range as well.”

Gennaji glanced at the railgun. His crew were resetting the launch mechanism, but they might not have time for another shot.

“Ory, I may need to use the ballbuster after all.”

“Captain…”

There was a pause, then static.

“Ory!”

The Sagittarius suddenly slipped sideways. Gennaji fell to his knees again as the gravity seemed to increase.

Shit. They must be tumbling. The centrifugal force might damage the hull if they couldn’t stabilize the ship.

“Karel!” he barked. “Helm! We have to…”

The intercom crackled to life again.

“…not responding to pings, looks dead in space.”

“Ory? What happened?”

“Corvus…hit, dead in…All…down.”

Gennaji struggled to his feet, grabbing the console for support. His body still felt abnormally heavy.

“Are we spinning?” he asked. Karel held a tether hook in one hand, unsure whether he should complete his Captain’s last order.

“Aye, sir. We…close to…emp charge, so our com…not 100%. Hang on…”

The ship shuddered again. Gennaji bared his teeth. Had the other ship also fired a railgun? The gravity seemed to lessen.

At least they had stopped spinning, he thought. Probably drifting, though.

“Ory?”

No response.

Gennaji swore. He unstrapped the tether and motioned for Karel to do the same.

“Andy, stay here and see if we can get off another…”

The com crackled to life. But it wasn’t their navigator.

“Sagittarius. This is Pleaides. We’re boarding you. Let’s talk.”


Next: Bringer of Light, Chapter 16: The Artemis (Coming Saturday March 13, 2021)

Still, they persevered!

Great job, NASA! Landing on Mars is always a tricky business.

Now all Perseverance has to do is find traces of life, save it without contamination, and then wait for another rocket, another rover, and a satellite to get in orbit so the samples can be sent back to Earth.

Piece of cake, right?
