The Expanse Season 5



This show has been good from its beginning 5 years ago, but this latest, abbreviated, 10 episode season moves a mile a minute as it twists, turns and shocks the audience.  Throwaway world building moments from earlier in the series come out of the woodwork to surprise and astonish.  

The fifth season is a 4 ring circus. Since everything in the solar system except Bobbi' and Avaserala's employment situations were, as far as the characters were concerned, going gangbusters at the end of last season, the cast goes on vacation...which is where most of them are when things go pear shaped. 

  The Expanse is an excellent example of fairly hard sci-fi, but beyond its realistic portrayal of space its characterizations and human drama are much better than most, more mundane series. 

The characters include a fellow who has (through either abuse, injury, or genes) basically a psychopath's brain, but who WANTS to be good..so he hangs out with what he assumes to be good people...to aid him in this difficult task. This season finally explains WHY he has this seed of goodness in the vast barren desert of his soul. It's very well handled. 

The only  even arguably unsatisfying moment in the entire season is an obviously late edit necessitated by production realities beyond the scope of this post, but your milage may vary, and it's a spoiler.

All in all this was probably the best season of this generally excellent show thus far. FWIW I think last season, while very good, was the weakest, though in retrospect, it set this season up superbly. 

If you're not watching this show, you are wrong. It's currently available in full, on Amazon Prime.

Why

...is NewsMax using the opening of this mix of Bad Apple for its overnight bumper music?





Did Zune get paid?

The Things One Learns From One's Comments

So I got a bizarre spam comment earlier which consisted of what appeared to be a long, obsequious biography of William Dafoe that had been Google Translated from some other language.


While I did not click on the link (obviously) a perusal of the URL indicates that the link was to a site warning that Mr. Dafoe is secretly the leader of a global conspiracy. 

I don't understand the world anymore.

What?

Oh LOOK!


It's all ok.

They're not afraid anymore!

It's all Oh Kaaay

There's no reason to hide anymore.

They can come right out in the open and say it.

It wasn't a conspiracy THEORY.



Saying something as spicy as this, even yesterday would get you banned from social media and perhaps loose your job or even your bank account. 

Now the conspiracy theory is a virtue signal. 

Why in God's name would Time publish this?

I can think of four reasons.

1: TIME is a principled publication seeking unfettered truth and published this bombshell out of a sense of civic responsibility. 

2: The editors at TIME have lost the plot and decided that the Q-Anon idiots should not be allowed to have all the fun. 

3: They are gloating and rubbing our faces in our helplessness to further demoralize us.

4: They aim to incite people on the right to act out of desperation and despair, as the degenerate fuckwits did at the Capitol last month, because they need a better Horst Wessel moment.

That last is kind of outre' but one wonders, given the tensions in the country, and the assumption that the editorial staff at TIME are not blithering idiots, if that isn't at least possible in current year. 

The message of the Time story, is as follows.

The Left control's the horizontal.

They control the vertical. 

There is no escape.

Not by boat.

Not by plane nor foot or even rocket.

 


Please dissuade me of my crazy rantings and troublesome conclusions in the comments. 

In case of the article getting memory holed, as often happens, it will be copied and pasted below the fold.

Ouch.

My steel toed boots did their job today. 

Though I was in pain most of the day at work.
Only after I got home did I realize HOW much pain I'd have been in if I had not had the steel toed boots. 
(Trigger Warning)

The whole foot is swollen but nothing is broken except the nail.

A New Take on NERVA

One of the Brickmuppet's Crack Team of Science Babes brings us this video on recent developments in the the world of rocketry.





The Scorpion is also described on pages 214-237 of the July 2019 issue of the Journal of the British Interplanetary Society. Almost everything in this ship is off the shelf, it's just tweaking existing technologies. Of course,  system integration can be fraught to say the least, but this doesn't require any real breakthroughs. 

In fact, this was initially studied as an alternate history study by the  British Interplanetary Society of what COULD have been developed given a more robust space program from the mid-'90s on. 




The ship design is pretty interesting, with a layout similar to the Eagles from Space 1999. That is is because the nuclear engines can't really be throttled, and landing in one's own radioactive dust cloud is not a spaceflight best practice. 

The landing engines are at 90 degrees to the main engines and the ship is designed to carry cargo in the manner of a flying crane.


"Tell them about the engine! The engine!"

'Kayy...

The SCORPION nuclear rockets are similar to the old NERVA rockets but use integral arc-jets in the nozzles to accelerate the exhaust to insane velocities. This gives both good thrust AND a very high exhaust velocity. It's not quite a torch ship but it combines the best traits of arc-jets and ion drives with nuclear thermal rockets. 

But wait. 
There's more!

Once a nuclear, thermal rocket is lit off, it becomes deadly to any unshielded people within about 100 miles. There is a shadow shield that protects the crew quarters of a nuclear ship, but operating around space stations, or even in lunar orbit passing over a settlement is problematic. 


This reactor design has enough thrust to allow for a shield that completely surrounds the engine, and the fuel rods can be retracted into a sort of safe when the engine is not thrusting. this allows the rocket 360 degree safety when the main engine is disconnected, allowing it to dock at space stations or land on moons near settlements without worry. 

Because the control rods, once activated, will be hot (thermally as well as radioactively) a liquid cooler and radiators will be required. This has the happy side effect of using the waste heat of even the inactive main engine to power a generator or thermocouple, allowing for enough auxiliary power to support an active cooling system for the propellant and any conceivable hotel load. 

Finally, the ship does have artificial gravity, but without the engineering malpractice involved with a rotating pressure seal. 

This is a really interesting design particularly when one remembers that it was designed with more modest lift capabilities than we now have in prospect in the form of Musk and Bezos's new large rockets. 



UPDATE: 
Unsurprisingly, it turns out there is a very good overview of this design and the engine at Atomic Rocket. It notes that the performance of this "Integrated NTR Arcjet" is close to that of a Nuclear Lightbulb engine.
