martian crustal thickness paper.
https://essopenarchive.org/users/549578/articles/627343-global-crustal-thickness-revealed-by-surface-waves-orbiting-mars
I've been interested in this stuff for a long time (welldweller) and with the depths available (martian crust is the thickest we know of) you could have any pressure/temperature you want just naturally.

>>15571442
I'd rather move a few kilometers each year than experience seasons or eve nights

>>15571496
SpaceX HAS FAILED

>>15571266
Have you considered going to florida/arizona every winter? It’s much less of a commute than whatever eyeball planet you had in mind.

>>15571474
How deep could we dig on Mars? I've always liked the mohole concept from KSR's Martian trilogy, but I doubt they're particularly realistic

Some people on Twitter are speculating that Blue Origin might sue Stoke because of their Aerospike engine

There is no fucking way, would they?

>>15571501
no dont fucking come here

>>15571515
BO isnt stupid enough to actually try that garbage.

>>15571515
of course they would, BO sues everyone and everything
sued nasa for giving HLS to spacex
sued spacex for landing boosters on a droneship
I don't know much about amazon, but don't they sue for this and that as well?

>electron
Why are we talking about model rockets again?

>>15571515
They might to stop Stoke. They did with SpaceX. They sued NASA to give them contract without competition after they lost

>>15571502
on average? 50 km
which is a lot thicker than both the earth and the moon (earth is on ave 24km thick, moon is around 38). The thing about martian crust though is that the conditions get more habitable as you dig deeper, and there may even be reserves of liquid water down there which mars has essentially soaked up. On top of that, the martian crust is very rich in thorium and uranium.
in tharsis (picrel) the crust extends 90km deep.

>>15571558

>>15571558
>there may even be reserves of liquid water down there which mars has essentially soaked up
cool, do you have any studies on this i'd be interesting in reading them

Are Tethered Rings good for space-launch infrastructure?

>>15571474
>a thick martian crust requires about
50-70% of the heat-producing elements such as thorium, uranium, and potassium to be
concentrated in the crust in order to explain local regions in the Martian mantle that
can still undergo melting at present day.
Mars will use nuclear power.

It’s not like there’s half a dozen or so American methalox rockets going into service within the next 2 years or anything

>>15571646
the US considered it back in the 90s/00s with the x-37b. also technically again in the 00s with prompt global strike.

>>15571646
They're thinking "REEEEEE F-16 EATS OUR BOMBERS" and that yeeting vaguely guided missiles from Tu-95s over the Caspian Sea will stop working once more Patriots arrive in Ukraine.

>>15571666

>>15571646

>>15571611

>>15571666

>>15571666

Why is it that China hasn't developed them until after other countries/companies have? Same with everything they do.

>>15571672
>SCMP is literal propaganda lol
It's also correct. They beat SpaceX.
>>15571666
>with a similar engine
that's a stretch.

>>15571646
Well, there's no reason why you can't use a Soyuz as a jumbo-sized V2. You wouldn't even need to include the Block-I upper stage. The ability to Amazon prime 10 tons of bomb from Plesetsk straight to Keiv is an interesting one.

>>15571646
lol, has space been weaponized like this before directly in a conflict? Starlink and spysats notwithstanding obviously
ballistic missiles are a thing, but have they actually been used in war?

>>15571683
That's called an ICBM launch and would result in the US nuking Russia.

>>15571442
>no krystal

I guarantee you there are too many problem within pockocmoc/the MoD that know it’s a fucking bad idea. And even if it somehow still gets greenlit it will be a 20 year era of R&D while all of putin’s friends line his pockets and no process actually gets made lol
So I’m not worried. Modern russiaspace is a shell of its former self by a long shot

>>15571719
*too many people within roscosmos/ministry of defense

>>15571646
Better question is, how do we blame this on SpaceX and Elon?

>>15571666
>world's first methane-powered rocket launch
Technically incorrect, it was the first methane-powered orbital insertion.

>>15571729
wait so the first stage isnt methane??

>>15571731
SpaceX had already been launching rockets with methane. Some of them even landed on methane.

>>15571646
For what reason, why not regular rockets

>>15571731
Terran 1 1st stage performed nominally.

ignore the twitter trannies. we can let china have one win

That looks like trash lmao

>>15571757
This rocket is retarded on the ‘Falcon 1’ scale, but actually pretty cool on the ‘amateur hobby rocket’ scale

Reminder that China is launching another methalox rocket at the start of next month and space still can't get off the ground.

I sometimes think humans would be better suited to eusociality, societies and countries would be a lot simpler to set up that way, you probably wouldn't even need taxes or a police force. societies would be ethnically homogenous, and very few would fear death.

Actual insect posting in /sfg/

>>15571863
Biologically this isn't really feasible for large animals, so usually they go for nuclear families, where the non-reproducing children serve monogamous parents for a time until they leave to form their own families. (see wolf packs, and normal, non urbanized non chimp humans). which is basically as close as you can get to eusociality without being eusocial.
I think it's obvious that eusociality would be more effective, much like dragonfly wings are objectively better than bird wings.

what's wrong with bugs? They're cool: ants and wasps are some of the most successful organisms on the planet, they're essentially a supersized and xenophobic family group. If you could see it action I think it would be extremely formidable.
It's hard to argue that the more rural specialized nuclear family is better adapted to the cramped conditions of a space colony or even just a modern city than a racially homogeneous eusocial group.

> LEO 1, the previous demonstrator for Telesat’s proposed Lightspeed network, launched in 2018 but recently ran out of fuel as negotiations to fully fund nearly 200 commercial satellites drag on.

> LEO 2 never made it to orbit. Built by SFL in partnership with Maxar Technologies, LEO 2 was one of 19 satellites lost in a 2017 Russian Soyuz launch failure.

>In the far future long after star formation has ceased the universe will be populated by sparse degenerate remnants, mostly white dwarfs, though their ultimate fate is an open question. These white dwarfs will cool and freeze solid into black dwarfs while pycnonuclear fusion will slowly process their composition to iron-56. However, due to the declining electron fraction the Chandrasekhar limit of these stars will be decreasing and will eventually be below that of the most massive black dwarfs. As such, isolated dwarf stars with masses greater than ∼1.2M⊙ will collapse in the far future due to the slow accumulation of iron-56 in their cores. If proton decay does not occur then this is the ultimate fate of about 10^21 stars, approximately one percent of all stars in the observable universe. We present calculations of the internal structure of black dwarfs with iron cores as a model for progenitors. From pycnonuclear fusion rates we estimate their lifetime and thus delay time to be 10^1100 years. We speculate that high mass black dwarf supernovae resemble accretion induced collapse of O/Ne/Mg white dwarfs while later low mass transients will be similar to stripped-envelope core-collapse supernova, and may be the last interesting astrophysical transients to occur prior to heat death.

Rumor is that he is considering buying Fox News now that it's a distressed property. Their ratings tanked after Tucker Carlson was fired and now they can't sell advertising. So if Musk buys it he can bring Carlson back and Fox will go back to being first in ratings and ad sales and he will then be able to get more advertising on Twitter too.
All of that only matters because if Musk buys Fox, SpaceX would have better TV coverage than NASA or any other space program public or private. NASA would be relegated to sideshow status, which is what it already is anyway.

SpaceX is targeting Tuesday, July 18 at 10:25 p.m. PT (05:25 UTC on July 19) for a Falcon 9 launch of 15 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. If needed, backup opportunities are available on Wednesday, July 19 at 9:09 p.m. PT (04:09 UTC on July 20) and 10:00 p.m. PT (05:00 UTC on July 20).

This is the 10th flight for the first stage booster supporting this mission, which previously launched NROL-87, NROL-85, SARah-1, SWOT, Transporter-8, and four Starlink missions. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.

> One of those companies is Astrobotic, which NASA selected in 2020 to deliver VIPER to a landing site near Nobile crater, a 45-mile-wide (73-kilometer) impact basin at the Moon’s south pole. The roughly $200 million commercial delivery arrangement allows Astrobotic to design and build the lander to carry VIPER to the Moon, a system that NASA would have developed—at greater cost—for the original Resource Prospector mission.

> The entire mission is projected to cost about $500 million, including the rover, its science payloads, and Astrobotic's contract, which covers the cost of the Falcon Heavy launch.

10 billion divided by 500 million is 20
copypasting some probe architecture and sending one with identical instruments etc to different places would also bring the cost down, I don't think getting the average price below 500 mil per mission is impossible?

The point isn't sex, but rather what comes after. Basically dealing with pregnancy and such.

If scientists/gov abdicate their responsibility, then private citizens will do it in thrill and find out whether or not babies will be deformed or not and whether or not pregnancy causes harm to the mother. Instead of finding out in a safe and controlled manner as a responsible scientists/gov, the gov is acting callous by not doing research. Possibly malicious because hatred of "evil rich" being in space may also play a factor in there to cause harm to the future people in space.

I think I may have actually been the first to put that forward as a semi-joke based on timing of certain noises in the video of the incident, and it got picked up from there.

> PlanetiQ’s satellites are equipped with receivers to pick up signals from the U.S. Global Positioning System, Russia’s Glonass, Europe’s Galileo and China’s Beidou global navigation satellite systems. Atmospheric density, which bends the angle of the GNSS signals, can reveal temperature, pressure, humidity and electron density in the signal’s path.

I read some speculation sometime that maybe Starlink could be used for the same too? knowing the location of the dish and satellite, you get some info about the medium between the two from the signal speed
but maybe not enough to be useful without more specialized instruments

I think there were a couple posts in various about the possibility of the rocket having been shot, but I think the meme really took off when SpaceX requested access to the roof of a ULA building close by as part of the failure investigation.

>>15574281
they actually did test F9 articles by shooting them

>>15574287
for what purpose?

>>15574315
to see if shooting it would cause the sort of failure they saw

it would be pretty based for starship to stage off a failing SuperHeavy and return precious satellites to a safe landing pad

>>15574333
This could work only in very specific circumstances

>>15574341
Why?

>>15573853
Holy shit it could probably FTS to orbit it it wanted to

>>15574351
The failure must be such that Super Heavy doesn't explode and can cut thrust because Starship almost certainly can't move away from an explosion quickly enough if it can even ignite its engines in time and it can't overpower Super Heavy's thrust. If it somehow manages to escape the booster, it now needs a safe landing location in range and then it also needs to manage its propellant in a way to actually get light enough to be able to land and support the loads of any weird manoeuvres this may entail. It also needs landing legs because otherwise you're probably looking at an SN10 landing every time.

>>15574429
>The failure must be such that Super Heavy doesn't explode
why? ship 24 did fine
>It also needs landing legs

>ship 24 did fine
How do you know that? And did it do fine enough for the Raptors to be ignitable?
>it's designed to land on the chopsticks
I'll give that I forgot about that lol, but that requires a chopsticks-equipped site to be in range and ready to receive, which restricts your options yet again.

>>15574465
Yes, I think Starship in-booster-flight abort is about as realistic as that one wacky Shuttle abort mode.

>pretending the stringer reinforcements are explosive charges

>>15574478
Anyone could theoretically build human flight space hardware. With Artemis at least, the gimmick is “build an airlock or arm or module or something and we will give you a free ride on our lunar-capable rocket and lander, aka the two hardest things only a select amount of countries really have”

>>15574465
remember when 7 raptors and the hydraulics were fucked and starship still had plenty of time to escape

>>15574479
>that requires a chopsticks-equipped site to be in range and ready to receive, which restricts your options yet again.
not really. a fully fueled starship can make it back to the landing site at any point in booster flight.

>>15574479
not sure that superheavy takes starship out of return to launch site range at any point in time whatsoever since most of the first stage is "up" not "across" and a returning rocket only needs to fight gravity briefly

>>15574488
No I don’t remember that, we don’t share dreams

>>15574496
now you're just disingenuous. the ship could have staged off and made it back safely especially with hot staging as soon as the abort triggered.
not even a question about that.

>>15574500
you are beyond retarded

>>15573329
Yeah I’m thinking 2 more weeks.

isn't there a Starlink launch happening soon? (third attempt)

>>15574533
holy seethe. the moment of abort there was no such thing happening with the booster.

>>15574537
>third attempt
isn't it the second?

Listening to the Payload Pathfinder podcast with Phantom Space CEO Jim Cantrell, he mentions they are in talks with the Bahamas to open a launch facility there

https://open.spotify.com/episode/3uoaHbHra2sV91dm2OGECY?si=36b0ef0cd3b54492

How are the supply chains there? Can they support launch?

>>15573856
Why do they have a fake satellite on display?
Also they revamped their website into mobile-first, hamburger menu shit

>>15574533
Notice how there is no argument.
Starship has real abort capability and due to its ruggedness can survive a variety of booster anomalies.

>>15574542
I just wanted an excuse to be creative kek, but really I cannot imagine the upper stage having the TWR to boogie out in time if SH is exploding under it. I certainly think this abort mode should be programmed into starship though anyways. Like shit if you’re gonna die you should at least ATTEMPT to survive. I also hold this view with Dragon—D2 has never ever had backup programming to try and land on superdracos in the event there is a severe parachute failure. That should be added even if aerospace parachutes are like 99.99% effective these days. Always nice to have options right?

>>15574490
>>15574491
That's good at least, but it still constrains you to a select few places and the other points still remain. Landing location is probably the least concern of this.

>>15574500
Considering the booster didn't cut thrust when abort was triggered and the rocket was already tumbling at that point, I very much doubt that. Starship with six engines has absolutely minuscule TWR so even with a quarter of the engines on the booster missing I don't think it could get away and if it managed to in non-flight direction the question becomes if it could survive the forces of that and/or right itself quickly enough and without colliding with the booster to even theoretically attempt RTLS and obviously the chopsticks can't catch yet.
CRS-7 was at least plausible if they'd had the code, this much less so.

>>15574537
A bit under three bongs, yes, but isn't it the second attempt for this one?

>>15574564
Laguna btw

Is there demand for a reusable small rocket?

>>15574554
>Considering the booster didn't cut thrust when abort was triggered
this was probably a mistake. if the engines lose communication they can't know whether an abort was triggered so they should just shut down right away.
>absolutely minuscule TWR
it's not that bad with three more vacuum engines. around 1.5 - 1.6

>>15574573
This is quite literally the first I have ever heard of this rocket

>>15574573
>Is there demand for a reusable small rocket?
no
>Is there demand for a small rocket?
also no

>>15574589
If I may add salt to the wound: most payloads sent to space really only need a smallsat launcher. Yet there is still not any demand for small launchers. This is how shitty the so-called “commercial market” really is (it doesn’t exist)

>>15574573
You can't make small rockets of any design viable without some kind of side-gig. Rocketlab works because they can provide everything except the mission specific parts. Stoke could work because they can provide mass return from LEO in addition to small launch. Someone whose plan is just "we're going to build rockets and they're not going to be very big" isn't going to find much success.

>>15574609
I think Phantom does satellite stuff on the side

>>15574578
>this was probably a mistake
Depending on what their documentation with the FAA said for this case, potentially a sizeable mistake, yes.
>it's not that bad with three more vacuum engines. around 1.5 - 1.6
That was however not the case for IFT, where it was more like <1.1. And that's likely still not enough for an abort without engines cut since Super Heavy has about the same TWR, same with Raptor 3 whether 250 or 270 tons-force. Also it's possibly still not enough in case of explosion even if thrust was cut and ignition somehow hypergol-like near-instantaneous, reminder that Dragon 2 has a TWR of about 4.
People need to accept that Starship abort from booster is extremely unlikely due to several factors, that's why they always talk about the hundreds of flights to prove reliability.

>>15574636
Not sure how spinhabs fit into this but hah yeah I agree

>>15574552
They could maybe rig up the Emergency Deorbit button to manually start the Dracos if there was a chute failure. Then there wouldn't be "what if it activates by accident" problems.

>>15574652
>”what if it activates by accident" problems
Nice I actually thought of that right before posting and it began to worry me.

>>15574652
i'm not sure dragon is capable of shutting down prematurely right now because they ripped out everything related to landing and also deleted valves after the explosion.
timing a suicide burn by hand at 2-4 TWR is hard.
and its impossible of course if you can't shut off because delta-v is higher than terminal velocity.

>>15574658
It's designed to handle a launch abort, and we know it doesn't dump fuel because they have to sniff for orange smoke bad before opening the hatch. As long as it doesn't run the engines too early, I don't see why it couldn't work.

>>15574660
Launch abort runs the tanks dry.
What I'm saying is if you can't shut them off early then there's no way to land with them because the dragon terminal velocity without chutes is lower than the escape system delta-v

>>15574658
It just needs to kill its velocity as it approaches pretty much exactly “0” in altitude (mean sea level). It doesn’t need landing hardware; if the parachutes on dragon failed then it’s guaranteed to be over the ocean

All i remember hearing is that dragon cannot land since they removed some valves for burst disks after the explosion.
I don't know how true that is because surely they still throttle to keep attitude but there's a good chance this would need a hardware change and recertification.

Spinhabs can have larger permanent/longterm populations which implies more volume of cargo in and out than one capsule every three months.

We need to find a way to make deep space as profitable as LEO and make human spaceflight proffitable. Spinhabs are a chicken and egg problem.
