Hey nerds it says in thr books that the stealth ship was only visible as a tiny spot in space 2 degrees warmer than background

Maybe people aren't paying attention to an infitessimally small spot in space thats 2 degrees warmer than background

Yeah expanse has magic stealth tech as well as magic drive tech.

People are sperging out over if it would be possible in real life, which is a big no.

....Is that still a valid thing to jingoistically blow out of proportion?


It'd be 100% possible to track everything in the system with modern technology, much less whatever they've got a few centuries in the future. I think the way The Expanse gets around this is that the solar system is developed enough that it's easier and cheaper to track traffic via the transponders every ship has to have on at all times. Now, I'm 100% sure that Mars and the UN have back-up thermal and optical systems to track everything if they ever need it, but they're not constantly looking at the entire system 24/7 because why bother? During peacetime, as long as you can keep eyes on the other guy's naval bases to see what comes and goes that's enough.

Also, stealth ships in The Expanse are SUPER stealthy, like barely warmer than the background at all and a tiny little object that nobody would notice anyways. Chalk it up to REALLY good heat sinks or whatever, Atomic Rockets isn't the be all end all resource for what works and doesn't work in this imaginary universe.

Even if you can theoretically track every object in the solar system, is that information going to be practically usable? All the known natural objects at least stick to their orbits, but between any uncatalogued natural object, every bit of space traffic (a lot of which runs dark), and any sort of derelicts or large enough debris, it seems like you'd have all of the problems of big data to deal with to actually find something useful in there. Unless you know specifically where and what to look for, what's to distinguish a stealth ship (that's not currently lighting up its drive, obviously) from an unidentified asteroid or random piece of space junk?

The Earth and Mars governments may well have telescopes noting every single thing that pops above the background radiation and sending it to a big computer, but all that means jack without some good way of separating the wheat from the chaff.

I'm genuinely curious - can we actually track every moving object in the system from Earth orbit today? Allowing for the fact Expanse probably has hundreds or thousand of ships, lots of them unregistered. Plus derelicts, and glorified tents sitting on asteroids, and countless bits of maybe functioning technology that got ditched when it broke or shot off of something bigger?

I'd imagine there would just be too many unexplained objects and false positives, but with the power of computing who knows?

If we're just talking space rocks in the real world? Nope, not at all. All those "passing us X distance from the moon" are usually only spotted weeks out.

The Expanse can handwave away tracking all ships because of rebroadcasting and the such. Its a pretty big deal in The Expanse universe to be running with no transponder on.

Yes, computers can do math (right now) that can pick out objects of note. Sure you detected 3 billion distinct objects on your scan pass, but you know which are ships and which are stations and which are asteroids because all that data is in the system. You're not shocked at that large rock that's been on your system forever because it keeps showing up exactly where you'd' expect it to be, you are shocked though when that asteroid changes course.

It's like how your eyes/brain work. You instantly pick out moving objects against a static background. Sure there might be billions of objects showing up on your scans, but you're looking for the ones that are moving in certain ways or on certain courses, which are very easy to pick out no matter how big the numbers are. Your system detects a cargo ship leaving Butterscotch station, it logged a flight plan and its current burn/trajectory match 100%. A military transport just left a small asteroid hanger, it's from a rival power so that's all you know but you give special attention to enemy stations/bases as well as any objects with courses going to/from them. Maybe you didn't detect the launch because it was launched while behind jupiter, but a new hot object was detected in the sky, after a couple passes you know it's exact speed and heading and can accurately predict its course. Since you do this with every ship in space you know that this is most likely the supply ship that docked a week ago making its return trip on schedule. But wait, it's course is slightly different this month so you point some extra attention at it. You get your best military telescopes to give it a closer look and you confirm it's the same transport, but it looks like they've welded some extra external cargo pods on but you can't quite read the registry numbers on the boxes, better pass this on to military intelligence.

Legally every ship and object in space would need some sort of official transponder, but tracking would never rely on it alone, it would just help match up objects with their owners and compare to logged flight plans and instantly red-flag any illegal flight or ship going off-course. A single ship off course or coming in too fast could destroy a station or crash into a city, a single forgotten cargo container could impact and destroy a ship. Tracking everything would be a life or death safety issue, add in the military and commercial/regulatory angle and the system would be all eyes on everything at all times with multiple layers of redundancy.

For the most part, yeah, but it sounds like that still relies on having the data in the system as you say. Nobody is going to record a sealed cargo crate some Belters used to squat in while waiting for their buddies' ship to swing by, or an illegal mining operation.

Or a ship that enters a scrapyard as an old freighter and leaves as two improvised OPA engines-with-a-seat-on-the-front. At which point how do you tell the cargo crate with life support bolted on from the dormant OPA pirate ship?

I don't know about system-wide (someone pointed out the planetary/moon occlusion problem), but we can't even track every Near Earth Object yet. As has been pointed out though, that's just a problem of funding/manpower.

Tracking objects coming from the same direction the Sun is, is an even bigger issue.

You made me think of a trilogy I read ages ago (the Heritage Trilogy), where there was a very creative attack that used the fact that everyone would be watching everything as a massive slight of hand. The books were fun, but unremarkable for the most part. The author did have some clever tactics for military engagements in space and on other planets/moons.

I had to search to remember if I had the details right and found someone had already summarized it on another forum.

quote:

Probably the most creative space tactic I ever read was in the (otherwise undistinguished, IMO) book "Europa Strike". It goes like that:

Evidence of extraterrestrial intelligence is found on Jupiter's moon Europa while, for unrelated reasons, tensions mount between US and China. An armed American spaceship is dispatched to Europa, while another is orbiting Mars. A Chinese ship launches, seemingly toward nowhere in particular. Few days after launch it detonates a fusion device, in a 100 megaton range, in empty space. No one in US can figure out the purpose of that, except possibly as a "message" -- demonstration of power. ("What happened to sending messages by e-mail?" grumbles one US Marine.)

What the Chinese spaceship actually did was fire an enormously powerful railgun, twice. The fusion bomb was a smokescreen -- the sleet of charged particles completely masked the EM pulse from firing the gun. Inert railgun projectiles are easy to get out of the way -- if you know they are coming. But no one does.*

One swarm of projectiles is aimed at Jupiter -- or rather where Jupiter will be some months later, when first American spaceship arrives. Needless to say, it is timed to arrive simultaneously with the said spaceship... and the projectiles have enough self-guidance to hit it. The other swarm is slower, and is aimed to where Mars -- and the second American ship, -- would be at that same time. Chancy, of course -- if that ship leaves Mars orbit in the intervening two months, it is safe, but the Chinese take this gamble. And the beauty of this is that if for whatever reason Chinese Politbureau decides to call off the attack -- no one will ever know it was underway! Just send a very short radio code to the projectiles, ordering them to miss their targets. And if they are needed, the attack is undetectable and unstoppable. Europa-bound swarm moves at over 100 km/sec, the Mars-bound one at about 25 km/sec. The course correction occurs within seconds from impact, and until then they are black, cold and silent.

So, here's the go to example that's usually used for this question:

https://www.nasa.gov/mission_pages/voyager/multimedia/pia17047.html

We can "see" Voyager with radio telescopes. Voyager is 116 AU away and broadcasting with a power roughly equivalent to a ham radio. Anything with enough heat for people to be onboard is going to be bright enough that we could scan the sky for it very, very quickly and it's going to be obvious enough that even modern computers could pick it out from the background with no problem. If travel time in the Expanse is measured in days then there's really no way that anything could hide, even if it was powered down and coasting.

The big issue is that any spaceship would have to be so bright that you wouldn't need sensitive or high resolution instruments to detect it. You could easily have some kind of very fast system doing a quick, continuous scan of the sky and then something with better resolution to focus in automatically on any anomalies.

Strange that no one ever live-posts during this show.

Anyway, I don't remember the meeting with Mao going down that way in the books, but maybe I'm mis-remembering.

And apparently everyone hates show-Holden, but I thought that was a pretty good "gently caress yeah, Holden!" moment at the end of the episode.

You guys get pretty wrapped up in Holden's obsession with destroying the protomolecule, but it's your basic Ahab and the white whale situation. Sure it's been done to death, but it's not egregiously done here. Eros is the inciting incident of it and then it just goes from there.

Holden is a little one dimensional and the acting isn't mind blowing, but I think his character is pretty consistent and understandable. It is become clear that containing the protomolecule is less and less possible, but I can see the logic of trying to close one loose end.

You're not, it's almost entirely different. No future events spoiled below, but:

At this point in the book, the political charades are still going on. Mao isn't on the lam, and neither he nor Errinwright has been publicly/officially implicated in any of the Protomolecule poo poo. Errinwright tells Avasarala to oversee Ganymede relief efforts, and to get there by way of Mao's ship. Avasarala knows Errinwright's trying to keep her from interfering with the real poo poo that's going down, but she doesn't see a way to refuse that doesn't take her out of the game, and she doesn't believe that he'd be so crass as to just kill her. The calculus changes when Mao lets slip over dinner that he's not going all the way to Ganymede with them.
