> “There’s nothing wrong with the engines,” he added. “We’ve lit the engines a zillion times on the test stand at Blue,” a reference to test stands by engine manufacturer Blue Origin.

> Assuming there are no problems with that firing, the last major obstacle before launch is completing an investigation into a March 29 incident during testing of the Centaur upper stage. Hydrogen leaked from the structural test article and ignited, creating a fireball.

> Engineers have isolated a small region on that dome where they believe the leak came from, as well as the likely ignition source. “I’m pretty confident that we’re going to find the leak, and once we find the leak we’ll know if we have to take corrective action or not on the flight vehicle,” he said.

> If ULA doesn’t need to modify the Centaur, that would allow the Cert-1 launch to take place in early summer, he said. “If we do, it could take longer, but I don’t expect it to get out of the year.”

article about the budget of artemis (previous thread had the financial plan as the OP pic)

> The space agency's chief official for human spaceflight in deep space, Jim Free, discussed the budget from fiscal year 2024 through fiscal year 2028. During this five-year period, the space agency will spend at least $41.5 billion on the Artemis program, when there is likely to be a single human landing at most. This includes some staggering sums for the Space Launch System rocket, $11 billion, which has already been developed for this mission.

> During his presentation, Free warned that even with the president's budget proposal, there probably was not enough funding to carry out the Artemis program as conceived, which calls for an initial human landing in 2025 (which almost certainly will slip two or three years), and a follow-up landing in 2028 (again, slips are expected).

https://spacenews.com/spacex-has-narrow-window-for-ax-2-launch/

>At a May 15 briefing, officials from the two companies as well as NASA announced they had completed a flight readiness review for the Ax-2 mission to the station, giving their approval to proceed with a May 21 launch. Liftoff of the Falcon 9 carrying the Crew Dragon spacecraft is scheduled for 5:37 p.m. Eastern that day, setting up a docking May 22 at 9:30 a.m. Eastern.

> “If we don’t get off by the 22nd, we’ll stand down with the Axiom 2 mission and turn our focus to the SpaceX-28 mission,” said Joel Montalbano, NASA ISS program manager, referring to a cargo Dragon mission currently scheduled to launch June 3. “Axiom, NASA and SpaceX will get together and look for the next best opportunity.”

Swarm and SpaceX story

>>15444370
whats the benefit of "outreach" exactly?
seems kind of premature and a distraction

Is it publicly known how much power a single starlink sat transmits with? V1? V2?

Anyone here worked at SpaceX? Should I apply?
Would be similar to an IT technician role. Not design/engineering, systems and support stuff. I live near a location that has a few matching roles for my work experience. I already have a gig but I'm bored.

>>15444395
yes

Esoteric Zubrinism

Did NASA's Eyes on the Solar System's presentation of the Lunar Flashlight Cubesat go off without a hitch

>>15444388
A single consumer hardware uses ~30(idle)-100 watt of power for single beam.

The satellite itself has ~16 different beams. If we say they use ~50 watts each, thats 800 watts of power constantly. Then it has a large battery pack and a large solar panel on it that can recharge itself, since the sat orbits the earth every 90 mins or so, so there would be sunrise/sunsets each time, if we assume each time, the battery is drained while the sat is on the other side of the earth, then starlink battery needs to be ~90 mins or lets be conservative and say 2 hours instead. So it would need ~1.6 kwh of battery. Or around ~40 kg of battery probably. Thats V1. I believe. And the whole sat weighs ~260kg.

V2 is supposed to be ~10x larger in mass and capability. So expect ~10kw of constant power and ~20kwh of battery weighing ~200kg.

>>15444410

>endless delays and excuses

Can someone explain why the Raptor V3 is a much better improvement? Im trying to understand how an increase in pressure helps performance, sorry if its a stupid question but Im a stupid person

>>15444426
Err I did the wrong battery weight calculation.

Lithium battery on Tesla is ~270 wh/kg. 1000 watt/270 watt = 3.7, thus 3.7kg per kwh. 1.6 kwh x 3.7 = ~6kg of lithium density in this battery. But we need battery pack level weight. If we look at Tesla Model 3's 54kwh battery, which weighs ~324KG. 324/54 = 6 kg per kwh x 1.6 kwh = 9.6KG. Still we can never know the true weight of the battery they use in Starlink, but I guess its similar enough.

Given that, the battery weight on Starlink V1 should be adjusted to ~10KG and Starlink V2 battery weight to 120KG for 20kwh.

>>15444426
Thank you. I am ruminating on a real bad idea that could involve weaponizing starlink. Do we know or have inference on what voltage it transmits at?

>>15444489
We know the standard home Starlink runs 120v-240v across the globe. Its unknown what the voltage would be on the satellites themselves. Its possible that satellites run at higher voltage. If we assume, they're using the standard Tesla battery pack, then that voltage should be ~400v.

>>15444436

>SLS

>>15444473
For starters it is directly related to thrust since that is the result of net forces on the combustion chamber and nozzle.

https://twitter.com/Erdayastronaut/status/1658502644376240128

McCulloch posted the abstract of his final DARPA report on Patreon, suggests average thrust to power levels of 0.25N/kW across all groups running experiments. Pic related. This means short of a nuclear powerplant with suspiciously high specific power (fusion with droplet radiators maybe?) or having 20% of spacecraft mass be thin-film ~1W/g solar arrays it's not going to be capable of impulsive maneuvers without further refinement, but it would be a good replacement for ion drives.

>>15444473
Higher pressure means more mass flow per second which means faster acceleration which means less aerodynamic and gravity losses.

>>15444517
Reports are meaningless, get back to us when a test sat demonstrates a velocity change with QI thrust

>>15444281

So if you had 1800 Starlink sats transmitting at a person sized target they would get serious radiation poisoning after roughly 116 days of exposure… hmmm…

>a conclusive test of QI using wide binaries
But what the paper actually did was just reprint some data from a decade ago, data which was claimed to be evidence on MOND.
Since then a better analysis showed the actual distribution looks nothing like the MOND (QI) predictions, because it's mostly driven by contamination which the original shitty analysis just averaged over.
Even MOND people reject this result. The MOND predictions were naive and ignored external fields.
Mike's paper cites the modern analyses showing that these results are fucked, but he still claims this is a "conclusive test".
He's right but he has it backwards. The distributions actually clearly show that the MOND without external fields (QI) are totally rejected by the data.
He is full of shit like always.

Note nowhere in that report is convincing evidence it exists at all. They cite "patents". Presumably including outright scams like Rossi's E-Cat. There are patents for time machines and other nonsense. Yes there are many patterns, but the fact they couldn't cite a single one which they found convincing tells you everything you need to know. The fact someone at NASA wrote a meaningless report is not proof of anything. The report is mostly just "what if". The fact they try to name drop companies instead of pointing to published experiments is embarrassing.

Note that the NASA report explains why they don't use the term "cold fusion", because the term is poisonous. They understand the need to appear legitimate, Mike doesn't.

Please explain what is unrealistic. In case you don't know me I simply use "space elevator" as a nick name. My real idea is a combination of space plane+sky hook+true Lunar elevator and all the tethers in between. There will be no base station on the Earth's crust but it will start at around 100,000 feet with w sky hook tether.

Thank you for an AWESOME point about the WEF!! I am aiming to one day be in charge of this whole deal! It will be run OPEN SOURCE!!! ALL TECHNOLOGY FREE TO THE MASSES NO ISSUES! Like the Linux of space flight.

I care nothing for money I care nothing for good food I care nothing for comfort and I have no dear of death. My only goal in life is to get average humans into space. I will be armed to the teeth to make this happen. That's all I will say about that subject but rest assured the WEF will not lay one finger on the orbital tether command line. We'll scuttle the ship before we turn it over to the enemy!

>>15444835
See above for info per your "fixed target" keep in mind I will be growing our security infrastructure in line with all orbital infrastructure. Contact with Jodi Foster is one of my favorite movies so I know what can happen.

Starship is a failure and it will never ever make humans a space faring race, your math is dead wrong and it's nothing compared to my plan. It will take Starship 10-20 years to launch a small manned mission to Mars.

My idea will see a colony ship with 1000-3000 strong leaving Sol System in 20-30 years.

Not to mention Start ship has failed to get to orbit and is year behind schedule. Starship also has huge issues with launch tempo which will bottle neck the lifting of raw mass off the crust of the Earth. You are 110% incorrect and make wild assumptions that the biggest scam artist of the 21st century, Musk, will follow through on any of his promises....you know like self driving cars.

>>15444920
>QUOTE BELOW

The tether alone seems like it would be the most expensive by far.

200 km (Sarmont non-rotating skyhook) of carbon nanotubes with a 1cm diameter (square cable, too lazy to pi) could hold its own weight x20ish. Are there other options for the tether that exist atm? Carbon nanotubes are pretty expensive and may not even be possible to make at that scale atm.

https://www.sciencedaily.com/releases/2012/04/120412105109.htm Using this source to price 200km assuming 1.4 grams per sq/cm, we get $420m-$980m which is kind of peanuts compared to its utility. Also, as mentioned by Isaac, this tether can be cone shaped since the lower parts hold less weight of the tether, so I guess this number can be halved.

I clearly must have fucked up somewhere in my reasoning. This skyhook would already been built if it were this easy to make a 200 km long tether. Any ideas?

Also, interestingly, Starship can launch a few of these tethers in one go, so launch cost seems pretty negligible at least for the rope. How heavy does the anchor need to be?

https://www.reddit.com/r/IsaacArthur/comments/gmrjrv/anyone_have_a_rough_cost_estimate_for_a/

It'd cost between 2 and 20 cents per kilogram? That's not sounding too likely, chief.

>>15444959
Explain it what logical world a horizontal take off and landing space plane burning simple jet fuel and operates off a normal airstrip is more expensive than the vertical take off highly complex Starship that needs specialized launch facilities that it LITERALLY BLOWS TO SHIT every time it takes off!?

Space plane takes off, meets hook, transfers cargo, lands. The only thing lost is a minimal amount of fuel and pound for pound it's a fraction of fuel that Starship uses not to mention its safer and more available fuel. Starship is not 100% reusable and parts that are can only be reused a hand full of times. The space plane could fly 100's of missions with minimal wear and tear.

That's like saying it's cheaper to take the space shuttle on your trip to Europe as opposed to a 747. On it's face what you propose is false and not based in logic, reality, or physics.

Do you retards honestly believe this or are you just this well paid?

>>15444964
The SR-71 BlackBird would count as such a plane and it flew for pennies on the dollar. All you pay is jet fuel cost retard, plus hundreds of flights with minimal part replacement compared to starship. Plus a huge increase in launch tempo will drive costs down in a huge way. You have no real point just baseless bullshit. But it is /SFG/ what do I expect right?

As opposed to StarShip @ Boca Chico that doesn't need special fuel or special staff?

Sky hook is a low tech satellite with a counter weight, NASA has already done small scale tests in orbit with great success. You are indeed....retarded.

Is Mike an electrical engineer? They tend to be schizos high on their own farts.

>solids are outdated in the era of RLV
Nope
Ammonium dinitramide + GAP can easily reach in the 310/330 vacuum isp range
But why?
Deep space heavy propulsion, the heavy lifter of a cheap expendable spacecraft that goes from LEO to higher orbits, Or even the second stage of a 3STO with a reusable S1!
Imagine
>High thrust compensated for low staging speed with RTLS S1
>Slightky (30-50) lower isp isn’t as much of a problem, just make the S2 heavier, it even makes S1 RTLS easier
>high density makes it fit easy in a Neutron-style cargo bay, leaving space for the third stage which brings the payload to high orbits

>>15445023
It's not a troll....it's the truth. Math doesn't lie anon. Do you think math lies!?

I spent YEARS studying all the issues with space and the bottle necks to become a space faring civilization. I concede we need chemical rockets to get to the next step but no one is talking about "space infrastructure" instead we focus on ancient chemical rocket technology and jet keep trying to reinvent the wheel. Why? I've done all the math with raw mass being lifted off the Earth's crust and even at best estimates Starship will never ever send more than a few hundred people into space. What good is that to anyone? It'll be 2050 and less than 1000 humans will have ever left Earth at this rate. We are literally wasting valuable time and resources on vanity projects that go no where.

I don't know if /sci/ censors archive links so fill in the blanks for a sky hook article.

The ONLY WAY we lift enough MASS out of the gravity well is with permanent infrastructure to get as much mass as possible into orbit as quickly as possible. With space planes we can launch cargo missions every day rain or shine with a hand full of Sky Hooks

They've got a lot of oldspace structural inefficiencies in how they spend funds, but their total budget isn't even $2B a year. There's just not that much money so if even a little is lost they feel it.

Can someone explain what exactly a spin prime is?

Tory Bruno's extremely handsome and well spoken.

>>15445433
SpaceX start raptor by shooting high pressure gas into the turbines
Spin Prime is when they do this while opening the main valves like they're starting the engine but don't light up the igniters that start the preburners and instead just fart some propellant onto the ground while measuring how fast the turbines spin to make sure they got up to speed

>>15445442

>>15445428
$2Bil is enough for Starship at USA wages. Efficient allocation if capital should enable significantly higher productivity at India wages.

>wake up
>"it" has been here shitting up the thread

>>15445448
You and me both, brother

>>15445446
The amount released is very small. A preburner test has significantly more chance to inadvertently cause an engine start, especially due to the unorthodox way that the raptor MCC is actually ignited. You see, as the unignited propellants flow through the [REDACTED]

It probably could. Problem is though the organism has to make a completely new body plan every time it infects something, from humans to dogs, an I'm assuming even plants. That would be impossible. It'd only be able to infect humans and the monsters would look the same every time.

Worst paper rockets as of now? IMO the worst is Jarvis, there will be literally no reason to fly Jarvis by the time its ready due to Starship

>>15445546
still a possibility but its down the line
you have to get starship working first, then get it reliable enough for human launches and then perhaps at some point you could look at earth-to-earth launches, but that would involve multiple launch sites in different countries (or coasts) so even if starship was human rated and working reliably it would take a while to get that approved and get through the red tape

>>15445666
A bunch of old guys (mostly retired aerospace engineers) who will constantly shart all over any fun or interesting project ideas you have, lol. Getting your L1 and L2 certs is pretty easy and can usually be done with the same rocket if you pick a good kit and build it with care, but L3 (where the fun begins) is an insanely huge pain in the ass that requires literal years of work and preparation. You literally need to find an advisor for your project and then present everything (build logs, flight electronics, simulation work) to a panel of people before launch. It's like a mini PHD. Once you have your L3 you can launch pretty much anything but if you wanna go higher than like 20k feet there are only a couple places in the country with those kinds of permits and they're all in California and Nevada. FAR (Friends of Amateur Rocketry) is probably the most famous.

It's like sex. You have to do lots of shit before hand for only a brief period of enjoyment. Where's the fun in that?

>>15445739
It's cringe but it has its place. Heavily documented L3 level rocket projects are one of the few remaining paths to becoming a "self made engineer" because the process is so autistic that you basically have to be a systems engineer to complete one.

>>15445742
The certs are legally required to purchase motors above a certain power level. Each cert gives you access to higher power motors. If you're making your own motors or doing shit with liquids then you don't need them.

>>15445459
I totally would wear rocket engine shoes if someone sold them.

Is this a reference to something?

>>15446043
no, I just expected a more interesting name. I mean, If you try to copy raptor, you should at the very least give it a good name.

>>15446019
>Not-Soyuz and Not-Orel

CASC's engine names are as uninspired as their rocket names

>oh you live in a spinhab? I'm sorry I thought you were an earther. You should ask whoever owns the hab to turn the rpm down, It wastes less energy and you guys might stop being manlets.

>>15446051
At least it means an Orel will get properly funde and finished in this century

>>15446084
Spinhabs WILL have acceleration > 1g
Spacenoids WILL be muscle bound dwarves
Well dwellers WILL suffer all of the negatives of gravity, and receive none of the positives

And yet no one has made 300+ isp solids despite it being so 'easy'.

>>15446136
Solids are mostly ICBM derived so shelf life is preferred over higher Isp. In civilian use we've got blushift's hybrid engine which is basically the 4ASS SRBee.

>>15445896
>thermal fission rockets
>also TWR=1 for first stages
>better ISP than chemical rockets
We aren't using this why? Government restrictions?

>>15446166
radioactive exhaust, so only good for upper stages

Skylab 2 was amazing. Those repairs they did in Apollo-era EVA suits? jeez

>>15446166
So you want a liquid hydrogen first stage only with a much lower T/W per engine and roughly three times the tank volume required.
>>15446175
>good for upper stages
Questionable

>>15446181
>but scaling bro, just scale it man

>>15445896
>Laser thermal rockets top out at T/W <0.1
hmmm

AGA when?

>>15446181
>still posting Eager's made up numbers

Why not just push against space?
Space is meant to be filled with quantum foam or some other quantum bullshit right?

>>15446253
that's not how momentum works. you're throwing material in some direction anyways

Another news just dopped. Starlink won against dish and other's objection against the sat internet freq usage.

>>15446295
Can you explain the wider context around this? Why did they not want to allow usage of those frequencies?

>>15446299
they wanted to use 12ghz on 5g networks

>>15446245
How the are they made up? He just assumed the tanks would have the same propellant density and mass fraction as the LH2 tank on Centaur. If anything he is favoring NTP too much by using a HEU engine, not factoring in long term propellant storage, and ignoring cost.

In before:
>Real NTP has never been proposed
>Those mission concepts that need dozens of tanks are outdated because umm reasons
Fucking tiresome.

>>15446303
the hydrogen used by NTP will have zero mass because magic

>>15446299
Dish and other's wants to use sat freq for 5g.thry claimed there won't be interference because sats won't be used in cities or some other nonsense. They claimed minimal interference, but FCC rejected this unanimously today. SpaceX and starlink argued that not only would the premise wrong about not using sats in cities but interference would be very damaging to users.

Dish is doing this to stop starlink. Dish doesn't use 5g. They've had sreq license to operate for more than a decade, but only for sats and they didn't use the freq because their sats are old. Dish claimed to want to repurpose it for 5g use.

cold fusion bussard ramjet first stages

There is some high falutin faggotry in /sfg/. Nobody even cares about the first test of the steel plate soon with S25?

>>15444473
it makes you go faster, harder, longer

>>15446352
nothing to say about it other than shower component watching for now

>>15446352
I CARE
but what to do

>>15446353

what is there to discuss?
work on the OLM continues, can't they static fires on a separate test stand too? not like they haven't done starship static fires before

>>15446352
No one cares about faggot Musk's steel cope plate. World's richest man, too stupid to dig a fucking flame trench. But let me guess.....he's special?

>>15445776
like a bidet

>>15445085
You're not as smart as you think you are... Worm. I'm able to knock out men with one punch. Take a look in the mirror.

>>15446352
They put plates under the suborbital pad?

>>15445776
you know how girls take the shower head out of its cradle, turn it upside down and, ahem, deluge their first stage? like that but it's booster-chan.

>>15445686
It turns out methane rich preburner exhaust and oxygen rich preburner exhaust are hypergolic at high enough temp and pressure

>>15446380
So, uhm
Art of Booster-chan on her bidet when?
Asking for a friend.
