Today, it is still the case that Joe Biden didn’t Win.

I realize that to some readers, this might be a shock; surely at some point things must change and Biden will have actually won.

But the past cannot actually be changed.

It will always and forever be the case that Joe Biden didn’t win.

And if you, Leftist Lurker, want to dismiss it as dead white cis-male logic…well, you can call it what you want, but then please just go fuck off. No one here buys that bullshit–logic is logic and facts are facts regardless of skin color–and if you gave it a moment’s rational thought, you wouldn’t either. Of course your worthless education never included being able to actually reason–or detect problems with false reasoning–so I don’t imagine you’ll actually wake up as opposed to being woke.

As Ayn Rand would sometimes point out: Yes, you are free to evade reality. What you cannot do is evade the consequences of evading reality. Or to put it concretely: You can ignore the Mack truck bearing down on you as you play in the middle of the street, you won’t be able to ignore the consequences of ignoring the Mack truck.

And Ayn Rand also pointed out that existence (i.e., the sum total of everything that exists) precedes consciousness–our consciousnesses are a part of existence, not outside of it–therefore reality cannot be a “social construct” as so many of you fucked-up-in-the-head people seem to think.

So much for Leftist douchebag lurkers. For the rest of you, the regular readers and those lurkers who understand such things: I continue to carry the banner once also carried by Wheatie. His Fraudulency didn’t win.

Let’s Go, Brandon!!

Hey China!

Or rather, “Hey Chinese Communist Party and your entire array of servitors, ass-wipers, and fellators!”

You’re not even worth my time this week. When you decide to act like civilized people, maybe I’ll give you a lesson or two in how non-barbarians behave.

Hey BiteMe!

[Language warning]

You and yours have caused a lot of injury. Literal injury with your war on people who don’t want to take an untested vaccine. When people die in an emergency room because a hospital won’t admit them because they haven’t had their clot shot, that’s a crime.

I’m going to address here the insult on top of the injury, because I am among the insulted. I still have my health but apparently you want me to live under the 8th Street Bridge (which actually isn’t on 8th Street, but whatever, that’s what the I-25 overpass over Cimarron is called), so maybe if you have your way that won’t be true for long. Dreadful time of year to become homeless.

No, you’re just trying to make me unemployed, because I won’t take your fucking shots.

Well, that threat is NOT going to work. I. Won’t. Take. Your. Fucking. Shots.

And it looks like enough people agree, that you’re having to back down, you worthless asswipe.

You’re LOSING.

You LOSER.

You Chinese-bought ratfucking traitor.

I would love to see you die an agonizing, humiliating death. (This isn’t a threat, because I am not threatening to cause that death. I am just announcing my intention to party if it happens.) It would be just recompense for the way you’re killing America…and millions of Americans.

His Fraudulency

Joe Biteme, properly styled His Fraudulency, continues to infest the White House, we haven’t heard much from the person who should have been declared the victor, and hopium is still being dispensed even as our military appears to have joined the political establishment in knuckling under to the fraud.

One can hope that all is not as it seems.

I’d love to feast on that crow.

(I’d like to add, I find it entirely plausible, even likely, that His Fraudulency is also His Figureheadedness. (Apparently that wasn’t a word; it got a red underline. Well it is now.) Where I differ with the hopium addicts is on the subject of who is really in charge. It ain’t anyone we like.)

Justice Must Be Done.

The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system.

Nothing else matters at this point. Talking about trying again in 2022 or 2024 is hopeless otherwise. Which is not to say one must never talk about this, but rather that one must account for this in ones planning; if fixing the fraud is not part of the plan, you have no plan.

More Stupid Orbit Tricks (Orbital Mechanics Part 3)

Well, this is a bit embarrassing. This is one subject that I actually have some formal background in, albeit from over thirty years ago, and I flubbed something in the first column.

[Math note: Take the velocity vector for the satellite. Normalize it, so its length is 1. Take the cross product of it and the z axis unit vector. Take the magnitude of that product. You now have the sine of the inclination angle. For those of you who didn’t understand that, be assured that it’s dead damn easy and you don’t have to watch the satellite in orbit to figure out its inclination, so long as your velocity measurement is accurate.]

Me being slightly stupid two weeks ago

You can certainly do this. It works as described. But it’s vastly better to take the dot product of the normalized vector with the z axis unit vector, and treat that as the cosine of the inclination angle. Why? Two reasons. First, the cosine could be anything from 1 down to -1, and those correspond to angles of 0-180 degrees, the exact range of angles an inclination can be. Second…to take that dot product, just grab the z component of the normalized velocity vector; no need to actually do the dot product, (v_x, v_y, v_z) (0, 0, 1) is a no-brainer.

OK with that out of the way, we can pick up where we left off last week. I gave you the formula for the period of an elliptical orbit of a certain semi-major axis (a), and used the special case of a circular orbit where a is the radius of the circle, to figure out the radius of a geostationary orbit. Here’s the formula once again:

(Last week, the one I found had GM where this one has μ; they’re the same thing, the gravitational parameter of the object being orbited, which is the mass of that object multiplied by the gravitational constant.)

It’s really easy to get from here to the speed the object is traveling at in its orbit. The orbit will have a total length of 2πa. (The circumference is 2π times the radius.) Divide that length by the period. Both of the 2πs cancel, and you’re left with a / sqrt of a³/μ, but that’s just the square root of μ/a.

Yes, this one has r instead of a. (This is what I get for copying and pasting formula graphics from Wikipoo; it’s not being consistent about using μ instead of GM, and the point I am about to make is obscured by using r instead of a.)

So does this mean that if you’re at a certain distance from the center of the object, a, and you’re traveling at speed v, you’re in a circular orbit?

Not necessarily. You’ll notice I said “speed” not “velocity.”

It is true that if you are at that distance, and traveling at that speed, your orbit will have a semi-major axis of a, but it won’t necessarily be a circular orbit; it could be an ellipse. The direction you are moving in at that distance matters. Draw a line from you to the center of the primary. That line defines “down” (even though you don’t feel weight while in orbit). Perpendicular to “down” you are moving “horizontally.” See the following very fancy (and stolen) diagram, where v is always in a horizontal direction:

If that is the direction you’re moving, and you are at the proper speed, you will be in a circular orbit. Otherwise, if you’re at the proper speed but not moving “horizontally” you are in an elliptical orbit whose semi major axis happens to match your distance from the primary. The more eccentric the orbit it, the farther away you will get from the primary at apoapsis…but the closer you will be at periapsis.

And this is where clean theory departs from actual practice. The theory pretends the entire mass of the primary is located at a point at one focus of the ellipse (or the center of the circular orbit). The fact of the matter is, the primary has a size, a radius, and if periapsis is less than that number, your time in orbit ends when you smack into the surface of the primary.

If you are in an elliptical orbit, then of course your speed at apoapsis is less than the speed we just computed, and your speed at periapsis is greater than that speed–unless it’s zero because you smacked into the surface of the primary. This formula is only good when your distance from the center of the primary is the same as the semi-major axis of your orbit. (Always true in a circular orbit, true at exactly two points of an elliptical orbit.)

Surely there’s a better formula useful in other circumstances!

Stop calling me Shirley, and yes, there is. It’s called the vis viva equation:

a is your semi major axis, and r is the distance from the center of the primary. Notice that you do not need to know the orbit’s eccentricity. More importantly, notice r and a don’t have to be the same.

(Also notice that if they are the same, things cancel and you get the circular orbit formula above. And notice also that if r is more than 2 times a, you get a negative sign under the radical. But that makes sense, it’s physically impossible no matter how eccentric an elliptical orbit gets, for you to be more than 2a away from the center of the primary, because the orbit itself is 2a in length, measured the long way.)

And now we have the background needed for today’s stupid orbit tricks.

Escape Velocity

If you set the semi-major axis a to infinity in the vis viva equation, you’re now thinking, basically, about an ellipse with apoapsis at infinity, which is to say, you’re not ever going to get to it, so you’re never coming back. Plugging that in to vis viva, the 1/a term becomes zero, and so escape velocity (at any given distance r from the primary) is:

(And now we’re back to GM.) You don’t have to be in orbit for this to work. So at the surface of the earth, 6,378 km from the center, escape velocity is roughly 11 km/s.

(And again, now reality crowds into theory. In reality there is more than just the earth and your spacecraft, there’s also the sun. You’ll get away from earth, but not from the sun…so you won’t travel infinitely far from the earth. To get away from the sun, you need 42 km/s (yes, even 150 million kilometers away from the sun). The earth’s orbital velocity of 26 km/s can help you with that, if you launch in the right direction; just add 16 km/s to get to 42 km/sec. This is how New Horizons was launched to–and past–Pluto.)

Note that the formula has a “greater than or equal to” sign; any velocity greater than this is also good for escaping, with some left over of course.

Changing Orbits

How do you change from one orbit to another?

If you’re in orbit you need some source of thrust, and the most common and obvious one is a rocket.

But here is the key thing…if you want to change from one orbit to another, you apply thrust where the two orbits–the one you’re in and the one you want to be in–cross each other. Because what you change with thrust is not position (not at the time you thrust, but of course later on your position will be different than it otherwise would be), but rather velocity. So the position before you thrust will be the same as your position after the thrust, but your velocity will differ.

Let’s go back to the eccentricity diagram.

Let’s say you’re in the red orbit and want to go into the green orbit. What you do is wait until you’re at one of the two points where the two orbits intersect–let’s pick the bottom one for this example, fire up your rocket, and change your velocity so that you’re now travelling on the green ellipse instead of the red circle.

But–and this is key–I said velocity not speed. The speed remains the same (remember, from above, that when those other orbits cross the red orbit, they’re at the same radius r and the orbits all have the same semi-major axis, a, so they have the same speed, just in different directions.

Velocity is defined both by speed and a direction of motion. In this case, you need to change the direction without changing the speed. This is a job for vectors! Just eyeballing it, at the bottom of the diagram where the red and green orbits intersect, you’ll want to point your rocket almost directly at the thing you’re orbiting, and thrust for a bit. That will result in your velocity shifting a bit downwards on the diagram, and you’ll be moving on the green ellipse instead of the red circle.

Remember what I said about being able to change velocity but not position, with thrust?

There was an egregious misunderstanding of this in a certain Star Trek: The Next Generation episode, Deja Q (from the third season). A certain planet was facing disaster, because its moon, formerly in a nice tidy circular orbit, was starting to drop inwards. With every orbit, the periapsis was getting closer and closer to the planet; eventually it’d hit the planet.

The Enterprise was going to try to pull the moon back into its proper orbit with the tractor beam.

But the Hollywood effects people were utterly ignorant of what I was just telling you. If you want to move the moon from that elliptical orbit back into its circular orbit, what do you do? You go to where the two orbits touch, at 3 o’clock in the diagram…and give it a good shove there. (You will want to speed it up at that moment; same direction, but make it go faster.)

Instead they depicted the enterprise waiting until the moon was at periapsis (9 oclock on that elliptical orbit) then pushing from there. Luckily they didn’t succeed, otherwise that moon would have ended up in a different orbit than what they wanted, quite possibly a very eccentric ellipse that would collide with the planet…oops!

Now a real starship crew would know this (unless they slept through orbital mechanics at Starfleet Academy), but Hollywood writers and producers? Nope. And either their “technical consultant” didn’t know Jacques Schiff about orbital mechanics (which, let’s face it, is an arcane specialty for people on Earth, though if we ever migrate into space in a big way, people up there will have to know it), or the Hollywood weenies decided not to listen to him.

(And let’s leave aside the fact that there’s simply no reason for a moon to suddenly have a shrinking orbit like this, in the first place! The only way it could happen, in reality, is if someone applied a small thrust to it at 3 o’clock, every time it was there, to slow it down and get the other side of the orbit to drop. I can’t think of a natural process that would do that. Once, yes, but every single time it’s at the same spot in its orbit?)

So there you go, an orbit change…and even an application (and you get to laugh at Hollywood too).

Hohmann Transfers

But what if the two orbits don’t touch? The short and glib answer is, then you use a transfer orbit; pick one that touches both orbits.

Hohmann transfers get used a lot by NASA for interplanetery probes. The orbits of Earth and (say) Mars are in very nearly the same plane, so you just pick an ellipse that touches both orbits, sort of like the way that wayward moon’s new orbit was touching the old one at 3 o’clock.

But it gets used for satellites too.

Imagine we have a satellite in a very low, circular orbit, say, 222 km above the earth’s surface or 6600 km from the center of the earth. And we want to put it into a geostationary orbit, which is at 42,164 km from the center of the earth.

We need a transfer orbit.

Like this one:

Our two circular orbits are connected by an elliptical orbit. (And yes my low special effects budget is in play here….the diagram is again stolen from Wikipedia, and it’s for the sun and two planets, clearly. Just imagine that’s Earth at the center instead of the sun.)

When you change an object from one orbit to another, its position doesn’t change, its speed does change. So what has to happen is the satellite, when it reaches 6 o’clock in orbit 1, has to change its speed to be appropriate for that elliptical orbit, at its closest distance, so now it’s in orbit 2. Then it will have to change speed again when it gets to 12 o’clock in orbit 2, to put itself in orbit 3. Needless to say, there’s a rocket attached to the satellite for doing this.

We know a for orbits 1 and 3, but we don’t know it for orbit 2. But look at it. The semi major axis of 2 is half of the long distance across the ellipse, and it should be pretty obvious that the long distance the sum of a for orbits 1 and 3. Because the top end of ellipse 2 is at the same distance as a for orbit 3, and the bottom end is at the same distance as a for orbit 1. Add them together to get the total distance, and divide by 2. A for the transfer orbit is 24,382 km.

Orbital velocity at 6600 km comes from . Using μ=3.986 x 10⁵ we get v = 7.771 km/second.

Orbital velocity at 42,164 km comes from the same formula and is 3.075 km/sec.

So now we need to use vis viva twice, once for r=6600 km in an a=24,382 km orbit, and another for r=42,164km in a 24,382 km orbit (the same orbit, two different distances). At 6600km, to be in that orbit, the spacecraft must be moving at 10.22 km/second (not that much below escape velocity!) and at 42,164 km it will be moving at 1.600 km/sec (it’s 1.59968 but I am rounding everything to four significant figures).

So at the point where orbits 1 and 2 touch, the spacecraft is moving at 7.771 km/second and has to speed up to 10,22 km.sec, which is a change of 2.448 km/second.

And at the point where orbits 2 and 3 touch, the spacecraft will arrive moving at 1.600 km/sec but needs to speed up to 3.075 km/sec to go into the circular geostationary orbit, which is a change of 1.475 km/sec.

As I said this is done with a rocket attached to the spacecraft. This rocket must be able to change the velocity of the spacecraft 2.448+1.475 = 3.923 km/second.

With that, and the mass of the satellite and of the rocket with empty fuel tanks, and the characteristics of the rocket fuel, you can use the “rocket equation” to compute exactly how much fuel that booster needs to do the two “burns” it has to do, in order to move the satellite to geostationary earth orbit (GEO).

The rocket equation sounds like a good thing to talk about in a future Saturday daily, assuming anyone in my audience still has eyeballs that haven’t turned into glass.

But in the meantime, you at least have some notion of how to send the GOPe to its most appropriate next convention site.

Obligatory PSAs and Reminders

China is Lower than Whale Shit

Remember Hong Kong!!!

中国是个混蛋 !!!
Zhōngguò shì gè hùndàn !!!
China is asshoe !!!

China is in the White House

Since Wednesday, January 20 at Noon EST, the bought-and-paid for His Fraudulency Joseph Biden has been in the White House. It’s as good as having China in the Oval Office.

Joe Biden is Asshoe

China is in the White House, because Joe Biden is in the White House, and Joe Biden is identically equal to China. China is Asshoe. Therefore, Joe Biden is Asshoe.

But of course the much more important thing to realize:

Joe Biden Didn’t Win

乔*拜登没赢 !!!
Qiáo Bài dēng méi yíng !!!
Joe Biden didn’t win !!!

Language Warning

In the next piece I had to discuss a particular topic. Unfortunately, I couldn’t discuss it without naming it. Therefore I apologize in advance for having to do so, and apologize to anyone offended by the sight of the name.

RINO McDaniel

As you no doubt know, RINO McDaniel got re-elected to RNC Chair Friday. I hope no one has already managed in the intervening time to suppress that memory; if so I apologize for the PTSD trigger.

RINO McDaniel isn’t the problem.

Let me be crystal clear on this, RINO McDaniel is a lower-than-whale-shit, piss guzzling ratfucking shit eating traitorous rancid syphillitic cunt. Her worth as a human being is substantially less than zero, any oxygen sucked into her lungs is wasted, and it would be, no matter what job she had.

I fear I haven’t been clear enough, but that will have to suffice.

But she is not the problem…or rather, she would not be a problem were it not for others. She’d still be as I have described, but we wouldn’t know who she is and would not care, because she could do no damage. She’d just be anonymous human refuse.

No, the real problem is the fact that a majority of the 168 top GOP people voted for her. And now that has happened five times so they cannot claim they didn’t know what she was.

In spite of the fact that under her “leadership” the party has deliberately sabotaged the will of its base, has deliberately refused to challenge blatant election fraud, had gone out of its way to ensure certain candidates do not get nominated, has diverted donor money to namby-pamby candidates who have all the electoral appeal of a puddle of dog vomit…and in general has done nothing whatsoever to help fix the problems that plague America.

However that last is to be expected; I cannot expect anyone who IS the problem to help FIX the problem.

RINO McDaniel would be powerless without an entire party leadership of the same mind as her. They want this dismal performance; they want to ignore the party base.

If she were to drop dead this instant, it would solve nothing as someone just like her would be elected by those same pustulous people.

According to Charlie Kirk, about 55 people voted against her, 10-12 wanted something different but were too chickenshit to do the right thing, and roughly 100 people voted for her enthusiastically, and even had the unmitigated gall to complain to Kirk about US. Fuck ’em. Rusty 12 gauge bore brushes would be too good for these arrogant pricks and cunts.

Every single one of those hundred is just as bad as she is. In other words, they are all worse than I described at the beginning of this piece. And no doubt those people in turn have people who supported them to be state party chairs and whateveritis they call the other two people from each state and territory who were voting.

It’s time to face up to the fact that the Republican party is effectively owned by the shit-eating RINOs. We’ve got more work to do, a lot more work, to make the GOP an instrument for the restoration of the United States of America. And that’s in addition to cleaning up our elections.

There’s no point in cleaning up elections just to elect ratfucking RINOs.

OK, hopefully now you will have some inkling of my true attitude towards RINOs. Sorry that words were inadequate to give you the full picture.

The Real Fascist is His Fraudulency Joe Biden*

*Or whoever has his hand rammed up that meat puppet’s ass.

Brandon (which I will use as a term for whoever is the power behind the Porcelain Throne) has thrown down the gauntlet…but in a way where most of America will never see it. The networks didn’t carry his tirade. CNN air brushed it (or whatever you call editing the red background) for its five viewers (who aren’t trapped in airports).

Luckily for me I live in Colorado, and therefore, despite my best efforts, I probably didn’t vote for Donald Trump.

Of course, for this purpose who I actually did try to vote for will be essential, and they undoubtedly know.

Come and get us, asswipes!

Justice Must Be Done.

The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system.

Nothing else matters at this point. Talking about trying again in 2022 or 2024 is hopeless otherwise. Which is not to say one must never talk about this, but rather that one must account for this in ones planning; if fixing the fraud is not part of the plan, you have no plan.

Small Government?

Many times conservatives (real and fake) speak of “small government” being the goal.

This sounds good, and mostly is good, but it misses the essential point. The important thing here isn’t the size, but rather the purpose, of government. We could have a cheap, small tyranny. After all our government spends most of its revenue on payments to individuals and foreign aid, neither of which is part of the tyrannical apparatus trying to keep us locked down and censored. What parts of the government would be necessary for a tyranny? It’d be a lot smaller than what we have now. We could shrink the government and nevertheless find it more tyrannical than it is today.

No, what we want is a limited government, limited not in size, but rather in scope. Limited, that is, in what it’s allowed to do. Under current circumstances, such a government would also be much smaller, but that’s a side effect. If we were in a World War II sort of war, an existential fight against nasty dictatorships on the brink of world conquest, that would be very expensive and would require a gargantuan government, but that would be what the government should be doing. That would be a large, but still limited government, since it’d be working to protect our rights.

World War II would have been the wrong time to squawk about “small government,” but it wasn’t (and never is) a bad time to demand limited government. Today would be a better time to ask for a small government–at least the job it should be doing is small today–but it misses the essential point; we want government to not do certain things. Many of those things we don’t want it doing are expensive but many of them are quite eminently doable by a smaller government than the one we have today. Small, but still exceeding proper limits.

So be careful what you ask for. You might get it and find you asked for the wrong thing.

Political Science In Summation

It’s really just a matter of people who can’t be happy unless they control others…versus those who want to be left alone. The oldest conflict within mankind. Government is necessary, but government attracts the assholes (a highly technical term for the control freaks).

A Few Things We Cannot Blame on His Fraudulency

I am pretty sure Joe Biden had nothing whatsoever to do with the 30 Years War that ran from 1618-1648 and probably killed about a third of the people then living in what is now Germany.

Nor did he cause the collapse of either Roman empire (Western, 476 CE, Eastern 1453 CE). Nor the ignominious failure of most of the Crusades. Nor the collapse of Bronze Age civilization around 1200 BCE (including the collapse of the Minoans and the blowup of Santorini).

However, my utter lack of ability to imagine how he could possibly be responsible for these things is not a valid argument against them, so I await correction if appropriate.

His Truth?

Again we saw an instance of “It might be true for Billy, but it’s not true for Bob” logic this week.

I hear this often, and it’s usually harmless. As when it’s describing differing circumstances, not different facts. “Housing is unaffordable” can be true for one person, but not for another who makes ten times as much.

But sometimes the speaker means it literally. Something like 2+2=4 is asserted to be true for Billy but not for Bob. (And when it’s literal, it’s usually Bob saying it.) And in that sense, it’s nonsense, dangerous nonsense. There is ONE reality, and it exists independent of our desires and our perceptions. It would go on existing if we weren’t here. We exist in it. It does not exist in our heads. It’s not a personal construct, and it isn’t a social construct. If there were no society, reality would continue to be what it is, it wouldn’t vanish…which it would have to do, if it were a social construct.

Now what can change from person to person is the perception of reality. We see that all the time. And people will, of course, act on those perceptions. They will vote for Trump (or try to) if their perception is close to mine, and vote against Trump (and certainly succeed at doing so) if their perception is distant from mine (and therefore, if I do say so, wrong). I have heard people say “perception is reality” and usually, that’s what they’re trying to say–your perception of reality is, as far as you know, an accurate representation of reality, or you’d change it.

But I really wish they’d say it differently. And sometimes, to get back to Billy and Bob, the person who says they have different truths is really saying they have different perceptions of reality–different worldviews. I can’t argue with the latter. But I sure wish they’d say it better. That way I’d know that someone who blabbers about two different truths is delusional and not worth my time, at least not until he passes kindergarten-level metaphysics on his umpteenth attempt.

Gold apparently was higher earlier in the week (roughly $1950), but has now receded. Still, it’s holding its current gains, and that’s a good sign for gold. Not so good for the US Federal Reserve Note (the “Fern” from its initials FRN, or “Federon” the entirely appropriate name of the monopoly money in the SolarQuest board game).

Orbital Elements (Part 2)

Before we continue, let’s back up just a bit.

Let’s look at the elliptical orbit again.

This rather cheesy (but it’s free!) graphic from Wikipedia shows 1) the farthest approach of a satellite to the planet (3), and also the nearest approach (2). (Never mind that the diagram is clumsily drawn so that it looks like the closest approach is somewhere else on the ellipse–I see that mistake a LOT and the planet should be drawn a bit further to the right.)

The farthest point is generically the apoapsis. When it’s Earth being orbited, it can be called apogee, when it’s the sun it’s aphelion. (Some other bodies have special names for it too.) Similarly the near point is periapsis (or perigee or perihelion…). The line connecting the two, along the long axis of the ellipse, is the line of apsides.

We’re going to need those concepts in a little bit.

OK, going back now to the satellite in the inclined orbit, there is a point when the satellite passes from south of the equator to north of the equator, this is the ascending node. And similarly, moving from north to south, the descending node.

Just giving the inclination, though, doesn’t uniquely specify the plane of the orbit. Let’s say a satellite passes through its ascending node at precisely midnight ET on January 28th. But, at that moment, it could be over Ecuador. Or Brazil. Or Equatorial Guinea. Or Kenya. Or Indonesia. Or any point in between.

So our next orbital element is called the longitude of the ascending node, Ω. (Capital omega.) Except we don’t measure the longitude on Earth’s surface…because that reference moves; Earth rotates. Instead, we measure it off a place called the “first point of Aries.” It’s basically the direction the sun is in as seen from Earth, at the moment spring begins in the northern hemisphere (or another way to put that, it’s the place where the ecliptic and the celestial equator intersect). This doesn’t move (much).

The following diagram shows an object in orbit around the sun (so it refers to perihelion, not periapsis).

Earlier when I was talking about earth centered inertial coordinates, I said the Z axis was the earth’s axis of rotation, and sort of blew off talking about the X and Y axes except to say they were in the plane of the equator. Now I can say that the line from Earth to the first point of Aries is the X axis.

So between i and Ω, we define the plane of the orbit of the satellite. a defines the size of the orbit and e the shape of the orbit.

We’ve still got two to go, and the diagram shows the first of the two, the angle labeled w (which should be ω, lower case omega). That’s the angle between the ascending node and periapsis, and is called the argument of periapsis. Without that, the periapsis could be over the southern hemisphere instead of the northern hemisphere; that’s two quite different situations.

The last parameter defines where the satellite is in its orbit at some particular time. This is done in multiple different ways. Perhaps it’s an angle, the true anomaly, with an implicit given time (the epoch). For example the epoch could be midnight, January 1, 2001, and the true anomaly would be where the satellite was in its orbit (measured from periapsis) at that time (or, if the satellite wasn’t yet in that orbit, you can back-calculate where it would have been).

It is also possible to simply give the x, y and z positions of a satellite, and also its velocity vector…at some epoch time…and one can convert back and forth between the two. Note that this method also involves six numbers. But the way I described in detail is the way that gives you a feel for what the orbit looks like; the x, y, z, and velocity vector won’t do that for you right off the bat.

Stupid Orbit Tricks

If anyone remembers David Letterman’s Stupid Pet Tricks, well this is my homage to that. I’m going to do a few of these, likely continuing next week.

Trick #1: Geostationary Orbits.

The Earth rotates in 23 hours, 56 minutes and 4 seconds. What, not 24 hours? The 24 hours you’re thinking of is with respect to the sun. But Earth orbits the sun in about 365 days…in other words, it travels almost one degree in its orbit about the sun every day. That means, as seen from Earth, the sun appears to move almost a degree in the sky every day, and if you want to define a day as the time between (say) high noon one day and high noon the next, Earth must rotate almost 361 degrees in one day to re-center the sun. We defined that time as 24 hours, so the actual 360 degree rotation in the inertial reference frame takes a bit less time.

Earlier I stated that the period of an orbit (the time the satellite takes to go around it once) depends only on the size of the orbit a. Implicitly it also depends on the mass of the body it’s orbiting, too. Here’s the formula:

T = 2 π sqrt( a³ / μ )

μ is the gravitational parameter, Newton’s gravitational constant multiplied by the mass of the primary (G x M). In metric units (kilometers and seconds) it’s 3.986 x 10⁵ for the Earth and 1.327 x 10¹¹ for the sun.

That formula gives you the period for a given semi-major axis a. If we do a bit of algebra, we can reverse it, and get the semi-major axis of an orbit with a specific period:

So with T equal to 23 hours, 56 minutes, 4 seconds…that’s 86,164 seconds. Shove that number through that formula and get: 42,164 kilometers or 26,205 miles. That number is from the center of Earth.

So any orbit with this semi-major axis will result in a satellite that goes around Earth in the same amount of time that it takes Earth to spin on its axis. So if it’s over Mar A Lago at 11:32 AM on one day, it will be over Mar A Lago at the same time the next day, and the day after that. That is a geosynchronous orbit.

Note, though that if the orbit is inclined (and one passing over anything not on the equator is inclined) or is elliptical, it will not stay over Mar A Lago 24/7. Inclination, of course means that the satellite will move over a range of latitudes from +i to -i every orbit. If the orbit is elliptical, it will move at different speeds over the course of the orbit, so instead of keeping pace with the rotating earth, it will move ahead of, or behind, some point on the earth’s surface depending on whether it’s moving faster or slower (respectively).

Therefore, a geosynchronous orbit like this is not terribly useful. But make it circular, so it moves across the sky at a constant speed as seen from Earth, and then make sure the orbit has an inclination of 0 degrees, so it’s always over the equator, and you have a satellite that, as seen from the surface of the earth which is rotating, appears to be stationary in the sky. That is a geostationary orbit, and it’s a special case of the geosynchronous orbit. It’s a circular orbit, so it has a radius, and that radius is of course equal to a of 42.164 km.

This is extremely useful because you can just point an antenna at that spot in the sky and the satellite is always there. So it’s great for propaganda TV or forms of meanignful communication. As such, positions in that circle are valuable real estate, and they’re specified in degrees longitude (i.e., the longitude the satellite appears to hover over). (Specifying a position like that only works for geostationary orbits.)

Trick #2: Molniya Orbits

But there’s a problem with this…one that’s not a big deal for us in the Lower 48 but is a big deal in Russia and Alaska. When you get to about 80 degrees north, that satellite will be on the horizon; anywhere above 70 degrees north and it’s less than ten degrees above the horizon, and your signal has to push its way through a lot of atmosphere. Clearly geostationary communications satellites don’t work well near the north pole (or south pole for that matter).

The Russians came up with a fairly effective workaround. It’s not as elegant as geostationary, but it can be made to work. It’s called the Molniya orbit. It’s a Russian inwention, so the original spelling is Молния. (In English it is usually mispronounced “mole-NYE-uh” but the Russian pronunciation is “mole-KNEE-yuh”.)

As you can see from the diagram, it’s a very elliptical orbit, at a high inclination, 63.4 degrees. Also the argument of periapsis (perigee) is 270 degrees; the periapsis is 3/4 of the way around from the ascending node (which is over Africa in the diagram); 3/4 of a circle is 270 degrees.
It’s a 12 hour orbit, not a 24 hour orbit, so twice every day it’s at apogee, the point marked 6 in the diagram (six hours since perigee). The satellite is moving so slowly near apogee that it almost tracks with the earth. So it can actually be used as a communication satellite any time between 2 and 10 hours after perigee. Of course on the next orbit, North America, not Russia, will be under it, so there needs to be another satellite with the opposite longitude of the ascending node to be over Russia then. And to be sure, there’s still a four hour gap (out of every twelve) in coverage while the satellite is too close to perigee. So the Russians likely have several of these satellites to ensure continuous coverage.

Incidentally, the inclination of this orbit must be at 63.4 degrees. It might look as if it could be adjusted a bit, but there are reasons (having to do with the fact that Earth is not a perfect sphere) that the orbit has to be at this inclination; any other inclination and the line of apsides will precess and the apogee won’t be in the right place for very long, in other words, ω will change. Eventually perigee will be over Russia and then it’s useless as a communications satellite because it will zip across the sky very quickly. (Accounting for “perturbations” due to other bodies or irregularities in the Earth is considerably more advanced stuff than I’ve gone into here. I’ve been pretending perturbations don’t exist to get the basic concepts out.)

Any of these orbits (geosynchronous, geostationary, Molniya) would be good places to send worse-than-useless RINO party officials to, provided they don’t collide with anything useful up there such as actual satellites. But of course it would be expensive to put them there. On the other hand, nothing need be spent on pressure suits, so some cost could be saved.

There are a lot more stupid orbit tricks, but the next ones I want to cover involve a little more background, so until next time…

China is in the White House, because Joe Biden is in the White House, and Joe Biden is identically equal to China. China is Asshoe. Therefore, Joe Biden is Asshoe.

But of course the much more important thing to realize:

Joining The Herd Of Lemmings

I’ve had cause to consider a few things. Maybe we’re going about it the wrong way, and we need to ditch Trump

Yeah, NO

Trump all the way! Why? Because being hated by the people who hate him is a sign of impeccable character, that’s why.

The haters can go fuck themselves with rusty twelve gauge bore brushes. I’d prefer ten gauge but that’s kind of scarce, so…I’m willing to compromise.

The RINO’s Dilemma

The RINOs who who have burrowed in and taken over most GOP organizations, from the state down to local organizations, have quite a dilemma on their hands, and most of them have their heads too far up their asses to realize it.

OK, I’m not talking about the liberal in a Republican area, who knows they’re in the wrong party, but is there because it’s the only game in their town; they hope to capture a nomination someday, at which point they’re guaranteed to be elected…otherwise, they never will be. These people are a hazard in any heavily conservative area.

No, I’m talking about the guys who are a little bit conservative and want to do some good by going into politics, and they’re in a closely matched area, closely enough that they can join the party they are most aligned with and still have a chance. They think the Democrats…particularly the ones who end up running for office…are nuts.

They don’t think much better of the Deplorable types, either. A bunch of bumpkins whose hearts are in the right place, mostly…OK a bit extreme. But they think Deplorables can’t understand that first you have to get elected, then work within the system to change things…a slow process. They genuinely want many of the things Deplorables want…just not as much. The government is spending too much. Or they need to spend money on highways instead of welfare for illegal immigrants. But they want to work within the system to get these things done.

Or maybe they think things are pretty close to ideal right now, and they want to nail it in place.

The problem is, that means they don’t stand for anything in particular. And it shows. They’re about as unappetizing to the electorate as a puddle of dog vomit. The folks in the middle, who they think they are appealing to because they themselves are not extreme, would honestly prefer a clear-spoken radical to someone who qualifies everything they say to the point where they sound like they don’t believe anything at all.

The problem these “Mild RINOs” have, is they just can’t see that. And the reason they just can’t see that, is their entire sense of self-worth is tied up in not seeing that. In their minds, they’ve worked tirelessly for their party, to keep those crazy Democrats out…only to have to constantly fight with a small number of crazy Republicans–who are only liabilities if they end up as candidates. They’ve fought the good fight, and if they can just find the right candidate, someone with some charisma, they might stop the crazies…without being too beholden to the OTHER crazies. In the meantime it’s not working. What’s a responsible guy in politics to do?

They simply cannot understand that the Republicans can’t succeed as the party of nothing in particular. Not really in the past, and certainly not today when people are starting to realize that no matter what they do in the voting booth, the country is still about to fly off a precipice. If they did see it, they’d suddenly have two choices: Go away and let the GOP succeed, or stay and fight. But “go away” isn’t really an option, because what’s the point of having a party now owned by the crazies, win?

Well, they have a dilemma…and WE, therefore have a problem. And we would have that problem even IF they realized that they had a problem…that they were the problem.

No one ever thinks they are the bad guy. Even Epstein probably thought he was the good guy. Right up to the moment where he didn’t kill himself.

So if you ever wonder why these unappetizing dufuses cling on even when their fingernails are being left behind…that’s why. They don’t understand no one wants them, and can’t imagine that no one should want them. And oftentimes their greatest pride is in all the hard work they’ve done for the party. They’re not going to give that up; it’d be psychological suicide.

If you’ve worked with these people, there’s a good chance you like them and consider some of them your friends. But even if so…we’re going to have to give them a good, hard shove. Because America is more important than those milquetoasts’ egos.

Justice Must Be Done

The prior election must be acknowledged as fraudulent, and steps must be taken to prosecute the fraudsters and restore integrity to the system.

Nothing else matters at this point. Talking about trying again in 2022 or 2024 is hopeless otherwise. Which is not to say one must never talk about this, but rather that one must account for this in ones planning; if fixing the fraud is not part of the plan, you have no plan.

Orbital Elements (Part I?)

Valerie asked me to explain what I was talking about when I talked about Starlink having to be in an inclined orbit, so here’s my attempt.

It turns out there are six numbers that can, taken together, uniquely and completely describe an orbit. Actually, there are many such sets of numbers, but the most popular ones are symbolized by the letters a, e, i, ω, Ω, and t.

But first we’ve got to make some simplifying assumptions. We are talking about two bodies (primary and satellite), and both can be treated as point masses.

As it turns out Newton showed that a spherical body (or whatever size) could be treated as a point mass, provided you’re outside the sphere and it’s radially symmetric. And what that last bit means is that if you start at the surface and drill down, you see the same things at the same depths, no matter where you start from. Earth turns out to have a solid iron core, surrounded by molten iron, surrounded by mantle rocks, surrounded by the crust; since these layers are pretty much the same thickness everywhere, Earth is spherically symmetric.

Well, almost. It does have an equatorial bulge, and the crust is of slightly varying thickness depending on whether you’re on land or out in the middle of the ocean, and the ocean itself doesn’t cover things completely. But it’s close enough for a first approximation.

You can, from an orbital mechanics standpoint, treat the Earth as if its entire mass were at a point at the center of the Earth.

One more assumption is that there is no atmosphere to cause drag.

Under these circumstances, orbits are governed completely by the force the primary (usually Earth) exerts on the satellite. That force “points” directly towards the primary’s center of mass. And in fact you can simply even further. The force on the satellite is proportional to the satellite’s mass; if you want, you can divide through by the mass, and just talk about the acceleration the satellite will experience as a result of gravity–that will be the same whether we’re talking about a baseball, or the International Space Station…or the Moon.

So we have two objects, pulling on each other, out in space. If they are moving slowly enough with respect to each other, one of them will travel in an ellipse around the other; it’s “in orbit” about the other object. (And technically the other object is also in orbit around the first one at the same time…but if one object is huge, like a planet, and the other is an artificial satellite, it is dang close to being “satellite in orbit around planet and not the other way around.”)

If the satellite is moving fast enough, though, it’s not going to go around and around the big object, though; it will escape, and not come back. This too is technically considered an orbit, but that doesn’t fit people’s mental image of an orbit, so I won’t insist on that here.

So, we have some object “in orbit” around the Earth. But that mere statement doesn’t tell you anything about where it will be, when it will be there, or how fast it will be moving, or in which direction.

That’s what you need those six numbers for. They encapsulate all of those things, and given those six numbers, you can (with a lot of computation), figure out where the satellite is, how fast it’s moving at that time, and in what direction. And you can pick any time, too; the computation is good for a thousand years from now, or last week. (Again, with those simplifying assumptions.)

OK, so what are they? Well depending on how much time I have to write this, I can cover two or three of them.

The first and most important is a. This is the size of the orbit. A non-escape orbit will be an ellipse of some kind (or possibly a perfect circle, but that’s actually just thought of as a special case of an ellipse). a is the semi-major axis of the ellipse…halfway across the ellipse the long way. If the ellipse is actually a circle, there’s no long way, or you can think of it as every diameter being the long way, and the semimajor axis becomes the radius of the circle.

[Johannes Kepler, around 1600, showed that all planets orbited the sun in ellipses (close to being circles). But that was simply showing that they do it. Newton was able to prove that an attractive force that fell off proportionately to the square of the distance would result in elliptical orbits, at least for things not escaping; thus he could describe the cause of all of those elliptical orbits and eventually show it was the same force that makes an apple fall to Earth or which makes the Moon orbit Earth.]

Now here’s the key thing–the amount of time it takes to make one orbit around some planet (called the “period”) depends only on the value of a. If the orbit is a perfect circle, it takes that amount of time. If the orbit is a narrow ellipse with the same semi major axis…it takes that same amount of time.

So, that’s one down: We have the size of the orbit. How about its shape? That is e, the eccentricity. There are multiple different definitions of this number, all with the same result. For our purposes, measure the distance from the center of the ellipse to one focus. Divide that by the semi-major axis. For a circle, the distance to the focus is zero (since both foci are at the center), so your eccentricity will be zero. For a really long, skinny ellipse the focus will be nearly at the end of the ellips and the eccentricity will be almost, but not quite, 1. You can get as close as you like to 1 without actually reaching it; just keep drawing skinnier and skinnier ellipses.

But everything I’ve shown you is two dimensional. What about three dimensions? Couldn’t an orbit be perpendicular to the ones in the last figure I showed, into and out of your computer screen?

Absolutely!!! And the next three numbers will describe the orientation of the orbit, in 3D.

But to describe the orientation with numbers, you must have a coordinate system and then you’ll want to do math. I can relieve you of the math (since I just want you to have a picture of what’s going on) but we’re going to need that coordinate system.

The first thing about that system is that it’s much, much more convenient if it’s inertial…in other words the coordinate system can’t move. That seems kind of trivial and something you shouldn’t have to mention, but that’s not true: we use a coordinate system every day that does move, and that’s latitude and longitude. Sure, 105 West longitude runs through Colorado, and will continue to do so–so it’s stationary, right? No. Colorado moves…because the Earth rotates.

So to best do orbital mechanics, you need a three-D coordinate system, that does not rotate with the Earth. You’d also find it easier if the system were a square grid, which latitude and longitude aren’t (even with altitude thrown in for a third dimension). The most commonly used such system is one called “Earth Centered Inertial (ECI).” In Earth Centered Inertial, every location in space is described by three numbers, x, y, and z. I won’t go too much into x and y (yet), but the Z axis, along which z is measured, is Earth’s axis of rotation. It goes through the north and south poles, and the center of the earth. If some object is on Earth’s axis, it will have a z value, but x and y will both be zero.

But that also means Earth’s equator has a z value of zero, just like Earth’s center does. So the xy plane represents the plane of Earth’s equator.

So what’s the first thing you can do with an orbit, now that we’re thinking in 3D? Up to now you’ve probably been imagining these orbits as being in the earth’s equatorial plane (if you’ve thought about it at all).

The first thing we can do is tilt the thing so it is no longer in the earth’s equatorial plane. So you can imagine measuring the angle between the plane of the orbit and the plane of the earth’s equator. But that’s not what we do, actually; it’s mathematically simpler to draw a line perpendicular to the plane of the orbit, and measure the angle it makes with the earth’s axis, i.e. the z axis. In the diagram below, h with the hat on it is perpendicular to the orbital plane (green disc) and forms an 11 degree angle with the north pole (k).

[Math note: Take the velocity vector for the satellite. Normalize it, so its length is 1. Take the cross product of it and the z axis unit vector. Take the magnitude of that product. You now have the sine of the inclination angle. For those of you who didn’t understand that, be assured that it’s dead damn easy and you don’t have to watch the satellite in orbit to figure out its inclination, so long as your velocity measurement is accurate.]

Or here’s another one, though it’s showing the angle between two planes definition:

Note that you can go all the way up to a 180 degree inclination, in which case you’ve flipped the orbit over as if it were a flapjack. The difference is, if the satellite were going counterclockwise around the planet before you flipped it, it’s now going clockwise. (Counterclockwise, as seen from over the north pole, is the “normal” direction, the one the moon and planets follow, and is also called prograde. Clockwise is retrograde.)

Note that a satellite will go over the north and south poles only if the inclination is 90 degrees. It will go over every possible latitude. This is called a “polar orbit” and it is the only orbit that can go over every spot on earth. (The orbit has to be of such a period that it doesn’t just hit the same spot at the same time every day, or you’ll repeat the same thing over and over again.)

If it’s only at a 60 degree inclination, it will only go as high (or low) as 60 degrees north (or south) latitude. But you can also get this with a 120 degree inclination! Because the plane of the orbit will at that point be at a 60 degree “slant” just like a 60 degree inclined orbit, but the satellite will be going “backwards” in its orbit.

For a satellite at over a 90 degree inclination, you can figure out the maximum latitude it will go over by subtracting its inclination from 180 degrees, so working that example, (180-120) = 60 degrees.

But you can actually work that backwards. If you’re launching from Cape Canaveral into orbit, what orbits can you get to, directly, without having to maneuver “up there”? (Such a maneuver is a “plane change” and is very expensive in fuel.) Well, ones that pass over Cape Canaveral of course. Cape Canaveral is at 28.5 degrees north latitude, so Cape Canaveral can only launch directly into orbits inclined at least that much. An orbit with a 20 degree tilt, for example, simply will never pass over Cape Canaveral. Cape Canaveral can launch into a polar orbit by aiming the rocket to the north or south, or into a 60 degree orbit by aiming northeast, a 28.5 degree orbit by launching straight east, but it can’t go less than that, because no 20 degree orbit can ever have Cape Canaveral in its orbital plane.

At least some of Elon Musk’s Starlink satellites have to be launched into a very highly inclined orbit, or they will never pass over the Arctic. Since Musk wants his starlink to be useful anywhere on earth, he has to have at least some of his satellites be in polar (or very nearly polar) orbits.

Well, with any luck I’ve achieved my goal of confusing Valerie quite thoroughly. And I haven’t even gotten to the other three numbers yet. Maybe some other time.
