Nice apu.

>>14873002
2 more DIVH launches left, ever. One in 23’ and another in 24’. Not sure how I feel about it. Part of me hates the rocket but the other part is ready for it to die. Letting go of Atlas will be even harder, spoiled by the fact that it’s last payload will probably be a fucking starliner

Is the sls rolling yet?

>Zero gravity doesnt exist in any form, the gravitational force has infinite range
>>14872470
>Zero weight is pretty accurate imo. Weightlessness is fine to refer to zero-g

Weightlessness in earth orbit, is still experiencing the gravity pull from the Sun and the Galaxy

OK.

I go between sol and the centauri system. Stopping the ship relatively to the 2 system. Do I float or what?

>>14873029
This is really an autistic argument of semantics, terms like zero G don't have to be literal when their purpose is to convey a description of a phenomenon that would take far longer to explain otherwise.

>>14873043
you are neither literally in zero G or weightless but the pull of gravity on you is so weak that you might as well be from your perspective

>>14873043
Anon you would still be in microgravity, now orbiting the black hole in the center of the galaxy.
The trick is that you can never be still in the universe, only in a reference frame can you seem to be still from your perspective

>>14873043
>>14873052
Well doesn't the universe have a center of mass? Like, geometrically or mathematically there should be some point where the gravitational forces in every direction balance out.

>>14873055
As far as we know, no. It’s like asking where the center of a line is that runs from negative infinity to positive infinity

>>14873002
Shhhh, don't tell the earthers about the lunar techno-cult.
It's a secret.

>>14873069
the universe is definitely finite so that's a retarded analogy. it might be sort of like the surface of a higher dimensional sphere where there is no center, still nothing to do with infinite.

>>14873029
>Weightlessness in earth orbit, is still experiencing the gravity pull from the Sun and the Galaxy
You're also still experiencing the gravity pull from fucking Earth.

>>14873075
>the universe is definitely finite
not true, we do not know for certain whether it is or isn’t. Either way all measurements seem to indicate that it isn’t wrapped up on itself like a game of pac-man so a sphere or higher dimensional sphere analogy doesn’t work

>>14873044
I’m pretty sure he’s a retard, especially if it’s the same anon from last year who tried arguing against the use of the phrase ‘microgravity’ like it was some jewish conspiracy or something

Is methalox really $6.96 a gallon?

>>14873080
>not true, we do not know for certain whether it is or isn’t.
we know for certain that it used to be way smaller and has been expanding since.
there is no way for a sane person to then conclude that it's infinite.

>>14873089
That’s not what was said

>>14873097
it is. the proposition of it being infinite is nonsensical thus it is known that it's finite.

>>14873089
You should go tell NASA that you cracked the code then. Can’t believe those poindexters didn’t think of this first!

kinda wild if true
imagine an utterly empty universe, now instantiate 2 protons 10^10^10^10 lightyears apart-how long would it take them to come together, assuming they didn't decay? After the ripple of gravitational attractino finally reached each of them, at what rate would they accelerate towards one another? How do you even calculatet his?

>>14873201
>>14873182
There is always gravity, because there is always mass. There is no way around this.

>>14873159
You want the launches to be even *more* late?

Is it true that we can detect black hole mergers all the way out at the edge of the observable universe?

>>14873206
Prove gravity then

>>14873211
That's what observable means.

>>14873216
No I mean with current instruments for detecting gravitational waves.

>>14873218
I believe so, yeah. One of the big revelations when they started detecting mergers with LIGO was that it was actually way more sensitive than they expected.

>>14873098
I love this shit. Who makes these?

>>14873182
>>14873200
gravity is not constant across your body length

>>14873230
It's closer to zero gravity than one gravity so you round down so it's equal zero.

>>14873230
Zero gravity is zero gravity

>>14873211
>>14873218
No it is not true. The distance to which they can currently be detected depends on the total mass. For a 100 solar mass boundary current detectors can detect them out to about redshift 1. This is a distance of about 10 billion lightyears, compared to the full radius of the observable universe at 46 billion lightyears. And note for lower or higher mass binaries the distance is much less. Note the most distant known galaxies are redshift 12-13.

ESA's LISA space gravitational wave detector will target much lower frequencies and hence much more massive black holes. For supermassive and intermediate mass black holes LISA can basically detect them over the whole observable universe.

>Weightlessness in earth orbit, is still experiencing the gravity pull from the Sun and the Galaxy
Weightlessness in earth orbit is still experiencing the gravity pull of the Earth. "Weight" is an actual force, the net force in orbit on say, the ISS, relative to the ISS, is zero. So you are "weightless". The acceleration due to gravity is not zero. Certainly, astronauts are not massless.
You measure weight from the reference frame of the scale, before someone tries to nitpick. You could try and do this on Earth's surface, and get a different weight than you would get if you used a scale normally, but that's stupid and no one does it. Weight is the appropriate word for the force generated by gravity, space is obvious not "zero-g", or there would be no orbits. Gravity is actually the dominant force.

>A fund will be established for the benefit of harmed investors, it said.

>>14873648
Twitter is the closest it gets. There isn't really a forum, people discuss things at conferences and in papers. Some collaborations have slack, but it's obviously not public. There are some alert networks for events like GRBs and supernovae, like the astronomers telegram, but it's for coordination not discussion.

Was dating all the newspapers today and decided to re-check the few Soviet newspapers I have.

Jews.They defecated through our economy, and we saved them. We shouldn't have. We took them into our own society. What were we thinking? They'll never change. They'll never change. Ever since 9AD, always the same. Couldn't keep their hands out of the temple money changer. But not our investors - couldn't be precious Boing shareholders! Stealing them blind and killing hundreds of people, and THEY get the compensation? What a sick joke! We should have stopped him when we had the chance. And you, you have to stop them!

Zero-g refers to the fact that you're experiencing zero g's of reaction force induced acceleration, retard. Nothing is impinging on you as a result of the earth's gravity pulling you against it or the sun's gravity pulling you against it or the jupiter's, because you and your ship are all in freefall together.

The universe can expand apart faster than c in far reference frames so certain parts of the universe are already causally disconnect from other parts, however they (meaning everything ever in the universe) was once directly within each other’s horizon (or rather, there was no horizon)

>>14873825
>everything ever in the universe was once directly within each other’s horizon
Inflation?

>>14873825
Okay so in this scenario the “universe” consists, hypothetically, of only 2 protons. They are both outside of eachother’s cosmological horizon or whatever, meaning the universe is expanding between them faster than they can “communicate” gravity with eachother. From each particle’s point of view is it basically the only thing in the universe? There is no way to ever detect the other particle? And despite being close to eachother at one point they both have zero external gravitational forces acting on them?

At this rate we are gonna get writing fluent diffusion models before Starship goes orbital.

That's what, like 60 miles? That's not too bad. Maybe an hour or so drive.

>>14873935
It's easy to get discouraged by a map like that, but it's not hopeless in the bright bits. I grey up in a bortle 2 (grey/black) but I've also done astronomy from the purple places in a huge city. You can still see quite a lot. If you live somewhere bright you will appreciate even a mildly dark site.
Also note that maps like that are only a rough guide. Some spots in a city can be much better if there is a hill or a valley that gives you some protection.

I took a train from Denver to Sacramento (and back when the trip was done) once. It took two and a half days each way not counting delays spent waiting in a siding for a cargo train to pass.

Or more just the earth, and small things near and around the earth are tugged along with earth. But if Earth was not here but you were, would you be attracted into the sun or orbit around it?

Your momentum is around it so even though you are attracted to it, this direct attraction will never pull you directly towards it?

>>14874093
Apparently we'll have a lot of uncertainty until it's passed by Cuba (late Tuesday). Fingers crossed for a "rush and RUD" though.

>>14874122
I'm a bit more concerned about NASA's hesitance to roll back than I am the actual storm. You'd normally expect NASA not to give a single fuck about delays of any kind and take the most risk-adverse path possible, but right now they're playing chicken with a category 4 hurricane just to avoid another trip back to the VAB and at worst a delay until early November.

>>14873115
If you've seen size comparison of earth and sun, then imagine a person floating next to earth, then the pale blue dot image, then the distance from the sun, whatever the Sun is doing that makes Earth follow it, is not really doing to the human floating around earth, or the materials and forces of Earth's motions are so significant and close to the orbiting human, that the human is just shielded from the sun's gravity, and craddled by the earths

>There is always gravity, because there is always mass. There is no way around this.
But the sun and earth are so much bigger than a stone and a human, what sun and earth do to gravitationally interact is likely different than a stone and human is able to effect the gravity field.

The magnitudinal quantity and quality difference between what can be achieved with ripples on a pond and what can be with tsunamis

>>14874137
Considering a rollback throws away (most of?) a launch window, I can't say I blame them for wanting a more accurate storm track.

Those flippant comments at the news conference though. wew lad

>>14874137
>>14874161
There's no way they don't roll it back. They have plenty of time to roll it back now, but they don't have enough time to roll if back if they try for the window on the 27th. They've only once (never?) even made it to the 10 minute hold, it would be dumb as fuck to go for a do or die launch attempt with a four billion dollar rocket that doesn't work.

Berger playing weatherman is a bit annoying.

>>14874215
He was literally the main weather writer for the houston chronicle for like 20 years you new faggot

>>14874161
But time isn't really something of significant value here. They don't have a "launch now or forever hold your peace" window like most deep space missions do, and the closest thing they have to competition is China who is still a decade or more away from their own mission. Delaying another month or three shouldn't be a big problem. The biggest issue would be if they can't get another six-month recertification for the SRBs, but even that's not a big problem since the booster segments for Artemis II have already been constructed. Rolling the stack back the VAB, dissembling everything, and then rebuilding it with the next pair of boosters would only be a delay of a few months.

But they REALLY don't want to roll back, and given how out of character it is I'm worried about the why. There's nothing special about the launch window on the 27th or the 2nd and there should be no reason to want to rush.

>>14874187

>>14874226
On the political side there's pressure both from "we can't delay Starship forever" and, more importantly, "we need a flashy win for the midterms". A rollback seems likely but a total reassembly (no matter how much sense it makes) seems very unlikely because it throws away the late October window.

>>14874244

Ships that are made especially durable that act like outfielder baseball gloves, an asteroid is slammed into missle exploded and like 10 or 20 large durable ships with open hatches propel to catch the largest chunks inside them, there can be cushion and padding on the inside, right when the asteroid chunk enters or before the ship begins accelerating in the direction of the chunks momentum, to ease the blow

You'd need one that's like 2 miles across to potentially cause a global catastrophe. Larger asteroids (i.e. Psyche) are more like 50 miles. I don't think weaponizing them is really viable though since you'd be better off with traditional rods from god.

Imagine what a nightmare that would be to get certified. At that point go one further and make the spacecraft into a nuclear bomb which detonates ~10 meters from the surface.

>>14874684
Given that the center of the universe is where we are right now, and where every other particles can also be considered the center of the universe, where space in between and outside aren't considered part of the universe, there is a center of mass. Thats a claim every particle can make

What's the size range asteroids that can be blown up and have a fleet of 50 ships standing by manuevering to catch the biggest chunks that will fit in their cargohold?

Large non nuclear missile creation should be made to go and blow up any blow up able asteroid heading this way, and have ships near to catch the chunks, so that valueable material can be extracted

>>14874694
The reason I say not nuclear here >>14874714
Is because part of the main interest of blowing up asteroids is trying to catch the chunks that break off and nuclear explosion would contaminate the valuable materials

One of the big unknowns about asteroid defense is how much force over how long a duration is enough to move an asteroid off its course in a controlled manner

Osiris Rex disrupting a rubble pile that dramatically also raises questions about how well you can disrupt what is essentially an uncoupled pile of rocks, and we still don't really know how big an asteroid needs to be before it condenses into a solid body

I don't get this type of pull string quote person about The Universe not having a center.

If everything started in a point, and then inflation and expansion happened from that point, at any given time in that process The Universe would be galaxies plotted points that could have lines drawn between them and then zooming out we would see galaxies as points making up some 3d shape, 4d when pressing play and time continues expansion and inflation occurs

>>14874719
>>14874721
Most asteroids are basically just dust clumped together with some big rocks underneath, detonating a warhead on one side of the asteroid would catapult ~99% of the asteroid's mass into a different orbit, likely missing the Earth completely, or into small enough chunks where they don't really make it down to the ground before burning up

>>14874725

>>14874721
>Osiris Rex disrupting a rubble pile that dramatically also raises questions about how well you can disrupt what is essentially an uncoupled pile
I hardly can believe a smart person could have the assumption that an entire asteroid is made of purely pebbles and dust because a lot of pebbles and dust flew up when the asteroid was landed on, it was landed on and hopped off of, a hard surface. It doesn't matter if there is 20 feet of dust, theres more than 100 feet more of solid asteroid, the intersting thing about the dust surface is does this imply interacting with all the radiation and gravity field on its orbit, 'chars' and strips and rips the surface of the asteroid?

>>14874738
Eh, seems a better alternative to some city potentially being Tunguska'd off the map

>>14874739
>If we think of the original "point" as a bucket of water that had bursted, then with the water "everywhere now" the center is everywhere as well
Press pause at any given time and zoom out

Oldspace would salivate over that possibility. Imagine not only that in this case they'd be successful at having robbed the taxpayers of all those billions to build a rocket that would end up never flying, and thus never failing, due to a external, natural cause; but also they'd charge several more billions to reconstruct the VAB. In addition, due to this accident, an excuse would be found for SLS production to morph into some "upgraded" version that's able to resist hurricanes or whatever, stealing more billions again, or, at the very least, it would quietly fade away but with at least having attained the main goal of the program: money and jobs.

Zubrin made an argument against nuclear electric disguised as an argument against the thruster, which is in part the fault of Chang-Diaz, also an ardent nuclearfag, for suggesting it be powered this way and pulling the idea of a 39 day transit out of his ass in hopes of getting funding when a reactor with an alpha of <1 kg/kW is the work of science fiction. As a comparison, the reactor for JIMO would have on paper been approximately 30 kg/kW including the heat rejection system but according to Kirk Sorensen who worked on the project they weren't close to meeting it. They even admitted in the VASIMR paper that <10 kg/kW isn't achievable with any turbo-Brayton reactor.

VASIMR accomplishes nothing that couldn't be done by nested hall thrusters like the X3, at the expense of a much lower TRL. They keep making excuses for why they can't even get it running for 100 hours. It's vaporware and cannot address the fundamental problem with nuclear electric.
>>14875060
The thrust to power ratio is just a function of its power efficiency and specific impulse. Thruster mass actually matters little compared to power system mass. VASIMR could literally weigh nothing and be 100% efficient instead of 73% efficient, it still wouldn't support the claims made by Diaz.

>>14875145
>They keep making excuses for why they can't even get it running for 100 hours.

The test was ended after 88 hours because a testing sensor failed, the engine was capable of continuing.

>>14875142
I'd actually be okay with that if we could replace all of this Saturn/Shuttle legacy crap with something like a giant-sized version of the launch pad boxes the Chinese use. No need to worry about rolling back to the VAB if the rocket is assembled right on the launch pad. No need for a colossal mobile transporter when all the rocket's segments can be moved using standard modular transporters. No need to worry about ever moving the launch tower or the GSE.

>>14875151
China doesn't assemble it's rockets on the launch pad.

>>14875149
That was over a year ago why haven't they reached the 100 hour mark since then? It's not an arbitrary requirement, they need it to advance to the next TRL and get more funding. Here is a direct quote from another time they shut down early, if it doesn't raise red flags, get your head examined.

>>14875163
Probably. How much have we paid for the Block 1B upgrades to the launcher that haven't even been started yet?

>>14875159
Their current engine, the VX-200SS, needs to be demonstrated in space to reach the next TRL.

>>14874831
I still wonder where they got 88000kg for Energia from? Wikipedia uses 100 metric tonnes and the NASA user manual for it made in the 90's put it at 105 metric tonnes.

>>14875159
The 28 hour run was terminated early at midnight on June 30 because that was when the NextSTEP contract ended.

>>14875170
>needs to be demonstrated in space to reach the next TRL
I think that's TRL 7 and they're only at TRL 5 according to a 2022 paper they put out. It was NextSTEP that required 100 hours which I assumed was based on meeting the next TRL but I don't know for sure. Either way, I doubt they'll get much funding now that Diaz's crewmate Charles Bolden isn't admin, there's no mission for an undemonstrated 200 kW thruster. Maybe they could test it on Gateway after it's in NRHO.
>>14875187
Why was then was 100 hours the goal for the July 12 test?

While you traveled 40 earth years away, and 40 earth years back,
80 earth years occured during your travel, because your travel took the duration of 80 earth years long

I don't think you will see it move at C, I think you will verify detect it at 1.5 C, but it is claimed that it moves at C,

Consider dropping a stone into a pond, the ripples, imagine ants floating on leaves moving all different ways, they may detect different energies of the ripples, but from our more absolute view we see the ripples move at a constant in The Absolute Transcendent And True Reference Frame, but in the subject ants reference frames the waves are impacting toward them, against them, to the side, diagonal, and it alters their speeds and momentums

I think you’re just over thinking it, and discussing this topic just brings out the dumbest of all anons. The simplest explanation is that “we live in a macroscopic world and we are very used to describing things in a macroscopic way, but when you go down many orders of magnitude in size our classical math doesn’t hold up so much anymore”. Simple as. Who even gives a shit if we are in some sort of simulation or not; it wouldn’t change your day to day life either way

You're talking nonsense. Ants could (if they were able to measure the velocity of water waves) measure them at different relative velocities. If the waves were waves of light then they would not (directly) find different relative velocities despite moving in different directions; it will always be C. This result is verified experimentally, however counterintuitive it may be.
>The Absolute Transcendent And True Reference Frame
Doesn't exist. Unless you can explain away the results proving that it doesn't exist. Also, the entirety of electromagnetism rests on the idea that the speed of light is a constant; it's not like Einstein came up the idea after a wild bender at his synagogue.

>but some of the conclusions of physics really do look like retarded hacks some programmer stuffed in trying to get things to work.
Well, to borrow a hypothesis from Quantized Inertia, if the conserved quantity is mass-energy-information, then the ugliest, kludgiest way to cram physics into the least amount of information would tend to result in a universe with the most budget left over for mass-energy.

Either that or we actually do live in a simulation and are rapidly outgrowing the original constraints. The reason physics is getting less and less elegant as we learn more about it would then be due to sloppier and sloppier hot-patches to keep the simulation from crashing, by ayylmao programmers drinking 20-dimensional coffee at negative 3 AM on a weekendmiddleinsideoutside.

What's some of the story line and plot points and character traits of a good space sci fi series, realistic, what could one be looking for in such a tv show? Hunky guys and hot girls scintilatingly flirting with one another with dramatic tension and drama?
Building, machine malfunction drama, endless romance,

One is kind of compelled to veer toward out there qualities, as so much has been done in tv and sci Fi in and not in tv.

Like some Issac Asimov Philip k dick Kurt Vonnegut blend Mars Moon Asteroid Mining Space Trucking show, can follow characters in these different jobs, can cover all realistic aspects of mars colony, but also throw in under layers of fantasy and fiction.

And/or (can be included sprinkled in each episode or some here and there less and more) the style of the series can almost be a serious manuel about what living in mars will and could be like, it can explore how the dangers will compel a certain communal aspect of presence and prescience, aspects of hierarchy, economy, psychology, romance, community, utopia

You are standing on shore of pond, there are 100 ants on 100 leaves, some traveling away from you, some traveling left, right, toward you, diagonal, every which way.

You drop a stone in the pond, water ripples; ants measuring the time it takes water to reach based on when they see you drop the stone, 2 ants one traveling toward you, the other traveling away, get hit at the same time by the same ripple, but they will have measured it taking different time?

star trek enterprise without vulcans or aliens. Just grumpy colonists each with exaggerations of real-world cultures and problems (but not shoved down your throat like it is in nuTrek)
IRL we know that some planetary bodies have more or less resources than others do. We know that political uprisings happen IRL all the time. Every great sci fi always has some sort of civil war woven into the lore. Take halo for example, it’s implied but never shown (the TV series doesn’t count). Maybe the mining federation headquartered on Mars is fed up with metal mining happening on Mercury and no one is paying their dues. A sect of miners have gone rogue to try and sabotage infrastructure there all while the government is trying to sort it out diplomatically but things have now escalated. An Orion warship is dispatched to apprehend wanted fugitives.
Maybe some colonists are sick of ever-increasing Earth taxation and do some shady shit in response
Maybe a colony on Triton has gone silent and now the Orion ship is on a months-long journey to Neptune to investigate.

It will no longer be Starship vs SLS as to which launches first, it will be Vulcan vs SLS.
Pray that it doesn't become New Glenn vs SLS.

The ants would measure the ripples moving at different speeds The ants would measure light from the same position moving at the same speed.

What are the odds of a planet with liquid water and an atmosphere forming at such a high galactic inclination? Shouldn't all of the more massive planetary nebulae have settled in to the main disc more or less?

Galaxies are almost 100% hydrogen. Individual planetary system makeup is pretty local considering the fact that heavier elements only accumulate due to supernova which is independent of location to the galactic center

What are the odds in general of there being a ~1atm ~1g planet anywhere with a breathable oxygen atmosphere and a pretty tame star? Even if it’s barren of life and is just rocky continents and a large ocean, but humans could theoretically step out and live on it without any external aid besides food? It’s not out of the question right? Like one has got to exist somewhere? There are non-biological ways of oxygenating an atmosphere and there are way too many planets around us to even count

In case you were wondering why NASA is hesitant

IIRC the biggest risk of abiotic oxygenation is that it's ephemeral. You need a continual source of oxygen to keep it from just reacting with other elements on the surface over time.

is a personal interstellar torchship with landers and cryo pods and infinite self-repair and isru capabilities REALLY that much to ask for?

What's more shocking than NASA being based for once by not rolling back until it's actually confirmed there could be a slight risk to SLS if left on the pad is the amount of people who are suddenly overtly concerned about its health. Just send that shit already.

Beamed-power. The catch? Your spacecraft would have to be on the order of centimeter-sized, your energy source on earth would be a HUGE power hog and would basically be a weapon of war, and you’d still have to wait a generation from our point of view to get the spacecraft to even our closest star
