JPL litterbugs

THIS is a flame trench, a 150m tall cave to withstand 50,000 tons of thrust, 730 GW of power, a 10,000,000 tons structure of concrete to contain the equivalent of a 30kT nuclear explosion in case of failure. All to send 1,500 tons to Orbit.

Honestly adore ISRO jeetbros

Why are Indians so retarded as individuals and as a country but can into space?

Answer the fucking question bastard

>>15387372
Legit question desu, the zubrin already made one 30 years ago

>>15387375
What if they make an onboard fuel generator

Is India working seriously on a reusable launch vehicle?
ISRO seems to have a lot of dynamism and a good engineering culture, they could easily overtake the ESA and Roscosmos in the future.

>>15387370
Because any G20 country can easily have their own space program and independent access to orbit if they really want to. They have the money and resources, orders of magnitude bigger than SpaceX's. All they have to do is to actually care to do something about it. Unfortunately, that's not the case for the majority.

>>15387390
>seriously
We made powerpoints

>>15387391
Ah yes, the classic yurozone cope.

>>15387385
I was initially a bit underwhelmed by the kino of this launch, glad the pics are coming in

Reminder that ISRO is still oldspace. We shouldn't be cheering for them.

Imagine if they had aborted the launch after engine ignition but the GSE was too fucked up to really safe the rocket

>>15387408
They're cheap though. It isn't like LM where it's a hundred billion plus tip, they're actually trying to do things efficiently.

I'm going to be honest, a lot of these starship/superheavy images don't really stir anything in me.
There is no sense of the real scale of the rocket and the footage is not as nice and crisp as the classic slow motion SaturnV footage.

I think as well I am pre-occupied with what they will need to do to prepare stage zero for future flights.

>>15387391
more like there is no big incentive thus far. Off world mining like extracting moons helium 3 deposits for first gen fusion reactors is a national motivation. Or not getting outgunned in orbit leaving your ICBMs vulnerable to things like mass sat constellation equipped with cheap interceptors. That can detect a launch and intercept it before it manages to even stage properly

Getting to orbit because I FUCKING LOVE SPACE leaves budgets tight and only restricted to the most interesting endevours like getting pretty pictures of other worlds

>>15387372
>>15387375
Have you not noticed the fact that they simply refuse to work on things that aren't critical path?
They're literally not even thinking about HLS and you expect them to do a sabatier plant?

>>15387508
Yeah hadn't actually thought about this
not only will Starship really jumpstart the space economy with cheaper payload to orbit which means a new wave of startups doing all kinds of shit related with that, it might jumpstart a new global space race (but perhaps only after some clear big economic driver is found, so it might take a while)
Starlink itself has given the military applications of new attention, but space isn't really seen as a significant economic area yet
Starship might make this happen if something like in orbit manufacturing becomes a large economic driver, but if that isn't the case then maybe the earth economy will stay somewhat separated from the space economy?

>>15387305
We've figured this out since the '90s.

>>15387520
This really is what constitutes the difference between BO and SpaceX.
BO has a billion R&D projects, SpaceX is working on exactly 8 things and they're all listed at the top of their website.

next orbital hop when?

>>15387558
4-8 weeks

>>15387558

>>15387558

>>15387558

Add like 6 months to that prediction and maybe some.

>>15387569
I never really trusted Elon's time frames. His are too optimistic.

>>15387508
Interceptor constellations aren't very economical, because due to the nature of orbital mechanics you have to cover everywhere at once, spreading your forces very thinly and plane change maneuvers are very costly/time consuming.

IMO immediate military goals in space are more about enabling or denying reconnaissance or communication capabilities.
In space military logistical infrastructure will be about supplying recon, com, as well as kill and jammer sats with propellant.
Maneuver in space, especially timely maneuver, is so incredibly reliant on propellant that any jostling for position around earth orbit will center around that resupply capability.
I think that is where a lot of the basic level of space infrastructure will come from.

>>15387605
If you say a time as the CEO that ensures it will with cerntainty not get done faster than that.

>>15387496
I feel like it would be less stressful if SS was simply its own thing right now, and not a part of Artemis. Art III really makes it feel like there’s this huge looming time table, before which a million things need to get tested

What went so wrong

>>15387613
Maybe NASA can modify Gateway to serve as a ad-hoc lunar lander

>>15387614
Too much thrust (and that’s a good thing!)

>>15387538
I predict heavy&cheap like lets say, steel production moving off world for industrializing space needs. With obviously mining preceding it. Because even with massively dropping prices per ton there still is "only" max 250 tons you can move per launch. For comparison sake Liberty class cargo ships, that were notorious in how fast and cheap they were with WW2 altering effects with the tons it could move. One ship could carry 10 000 tons, often more as they were frequently overloaded.

Heavy tonnage materials will be in high demand for orbital installations like dockyards. While complex chain end products like high end electronics or fuses for nuclear warheads used in mining or military platforms or even experimental projects like orion will be produced on earth.

Kind of like a traditional colonial empire that extracted resources from the underdeveloped provinces to be shipped to the core for processing. Culminating with the finished complex goods being sent back to the colonies with a high upmark

>>15387613
I dunno, they've already landed on earth and that's way harder than landing on the moon.

So long as reliable orbital launches are happening within a year or two, the timeline should be fine.

>>15387577
I was referring to NERVA but ok.

>>15387627
you say that like it's easy
just look at the falcon9 timeline. and that was a smaller rocket with less experimental shit in it

>>15387627
That’s a good point. Also it’s tentatively scheduled for December 2025 and it might slip outside of HLS readiness simply because of SLS

>>15387627
>they've already landed on earth and that's way harder than landing on the moon
From a fuel slosh and margins standpoint sure.
There's additional complexities such as not digging a huge hole, damaging the engines and thus killing the astronauts and terrain relative navigation.

>>15387614

>>15387639
SpaceX has totally sunk cost fallacied the OLM/Stage 0

>>15387637
Also in the broader scope that whole orbital refilling thing requiring at minimum 1 depot launch 8 tanker launches and 1 HLS launch consecutively.
This requires Florida to be operational which requires Starship to be proved safe in Boca first (Elon said this himself)

>>15387259
Actually, there are plenty of actual alpinists who have climbed Everest with 0 supplemental oxygen. Its just your average western tourist climber who has little mountaineering experience generally can't do it.

>>15387635
What is the current status of Artemis II’s SLS?

>>15387634
Vertical landing was the hard part. If they've managed to knock that out in a few years, I think launch would be a bit easier. Granted, any system has hiccups and unanticipated behaviors that need to be ironed out, but I think just getting the rocket up would be a bit easier.

>>15387642
There is no way thats happening without SpaceX using the OG LC-39A flame trench and I suspect both them and NASA are beginning to realize thats the best, cheapest, fastest path to operational Starship

>>15387647
>but I think just getting the rocket up would be a bit easier.
Still falling for the first stage vs second stage fallacy.
Super Heavy is decidedly harder than Starship.

>>15387558
6 months

>>15387650
Is it? Vertical landing is a brand new technology. People have been doing vertical launch since the 40s.

The engines already work, so that's the biggest R&D issue dealt with. All that's left is just to make sure they work consistently and the stage separation doesn't sperg out.

how do we get /sfg/ to be awarded a SBIR from NASA

>>15387649
Baseless assumption.
There is not going to be trench in Boca so in an accelerated timeline they would most likely copy the same design at the Cape.
It would be a huge effort to redesign 39A and the booster to support launches.

>>15387659
>tower segments and arms already built

I’ll gladly eat crow on this but right now I’m too scared to trust Starship as the primary lander, especially with the expected dates for this program being so close.
It’s like watching Falcon 1 blow up and then expecting Falcon 9 to somehow bring up Bob & Doug in only two years

>>15387656
You're forgetting reentry in general. The tiles have yet to be tested in real conditions.

>>15387645
Right but that's still 10 times more O2 than you can realistically get on Mars without a pressure suit.
The gas trapped in your blood and cellular fluid is also going to start to come out of solution beyond the Armstrong limit.

>>15387663
spaceflight is supposed to be dangerous
if it wasn't why is it this expensive

>>15387662
Yes and guess what they were not built over the 39A flame trench.

>>15387663
Isn't Artemis delayed because of the space suits anyway?

>>15387670
They are currently in the SpaceX site waiting for installation, SpaceX is currently constructing a crew access tower for SLC-40...

>SpaceX will just sit idly by while OLM gets repaired before launching Starship again
>SpaceX has approval for sub-orbital hops from Boca Chica still

AHEM

Wenhop

>>15387666
The HLS doesn't reenter.

As for the Starship tankers that are refueling the HLS, it doesn't matter if they blow up. They're cheap enough to run in expendable mode, and no crew would be in danger.

>>15387658
Most likely: starting a company that makes a small but important part for a larger company
Ideally: shitposting satellites

Couldn't they build like a steel bowl structure to direct gas and shock up and away from the launch site?

>It's not that easy in thrust divertery

>>15387681
Yes and fill it with water for extra cooling and acoustic attenuation in addition to water cooled steel bowl

>>15387684
>steam punking intensifies

the concrete failed because the engine blast got under it which lifted the pieces up. So why not just have the same simple concrete pad but thicker?

Honestly all of SpaceX's problems at the Boca Chica launch site are because its wetland/environmental protected status

The solution is environmental permitting reform, fuck your wetlands

>>15387681
There's no advantage of this over a flat plate.
The heat load would be higher as well as the acoustic load.

>>15387666
I honestly don't think that re-entry it's self will be a massive problem, the Shuttle used the same tiles with a much more complicated design and less margin.

If there is an issue it will be the practicality of rapid reuse with the tile system.

>>15387689
>Honestly all of SpaceX's problems at the Boca Chica launch site are because its wetland/environmental protected status
wrong. they would not have built anything different about the olm were it not wetlands.
the only thing they might have done is put the fuel farm further away.

>>15387688
It got under it because it bored a hole through it, which is still not ideal.
That's still going to result in high velocity concrete shrapnel and lengthy repairs.

>>15387688
You want to pour new concrete for every launch?

>>15387588
As if they hadn't already had their own drones fly over before he wrote that

Suborbital hops back on the menu?

>>15387702
No
Waste of time

>>15387642
at this point Nasa and larger government bodies like military are drooling as the thought of what this thing can do when the kinks are ironed out. They will let it into the cape as soon as it can launch 2-3 times without major hickups. From what I understand of burger loicense wankery the cape has dedicated launch corridors where they are much more free to operate in peace

>>15387707
Get good re-entry data

there are 3 rockets in range of Saturn V:

N1: launched 4 times, exploded 4 times
SLS: works, but costs double of Saturn V and is weaker
Starship: launched once, couldn't even get higher than weather balloons or Bezos' rocket

50 year later why can't nobody beat the National Socialist rocket?

why not put the tiles on a F9 S2? get re entry data that way.

imagine the night launches

>>15387558
I'm going to hold on to some optimism here. Unless something stupid happens, they'll wrap up their investigation of damages this week and start repair work. There's a ton of damage and a ton of work that needs to be done but most of it can be done concurrently so really the OLM is probably the biggest limiting factor. Give them a week or two to excavate, another week or two to pour some new structure and backfill. Another couple weeks to get this water cooled steel plate down/deluge or whatever. A couple more weeks to complete testing on B9+S25 and if everything goes right, 4th of July.

>>15387702
The only reason they would go to back to suborbitals is if they encountered difficulties in landing the booster and starting knocking out simulators with dumb Starships and less engines.

Will booster 9 starship 25/26 launch or will they have updated models by the time OLM is repaired?

>Raptors regularly exploding at mcgregor
>2 raptors out in a few seconds, 50% Static fire

meanwhile BE-4 is ready for launch

>>15387730
>When will /sfg/ accept that Raptor is not a reliable enough engine YET for a super heavy launcher?
They already have, which is why they'll keep testing it until it is.

>>15387714
The nozzle sticks out, it has no way of controlling itself and it doesn't have a nose cone.

>>15387738

>>15387712

>>15387738
Man just wait till Monday, sie**a club and all the usual suspects will throw a fit

>>15387730
does it need to be 100% reliable? there is some threshold above which the launches still work

>>15387738
takes a while to write about stuff, get to the site to take pictures etc

raptor should've been a methane Merlin

>>15387754
> there is some threshold above which the launches still work
yes and only spacex has any idea where it is, and they aren't 100% sure and they aren't going to tell us

>can confirm very little onboard footage, most cams die immediately on liftoff
Fuck, got this from a reliable source, don't get your hopes up for extensive onboard footage

>>15387754
If they just want to get to orbit they can stomach quite a bit of failures with their engine out capability, but reuse lowers the payload margins and the landing maneuvers are more sensitive to engine loss. Add that up over dozens of flight and current raptor is clearly not reliable enough for a fully and quickly reusable raptor.
I don't think there's a fundamental problem, I just don't think it's there yet.

>>15387714
The tiles are the same as the shuttle, they are a known quantity, it's the nuances of the aerodynamic structure of the starship in re-entry (Ie the flaps and hinges) that need testing.

Plenty of engines became more reliable over time; the RD-170 familly were some of the most notoriously hard engine to develop and they were perfect on almost a hundred atlas V launch.

This is subject to change as Starship becomes more and more developed. Obligatory fuck Blue Origin and oldspace. I just think the “safe” design has the lowest risk

>>15387756
The raptor engines on the OFT were probably mostly caused by the 3km/s concrete shrapnel

>>15387730
Raptors exploding at McGregor doesn't necessarily mean anything, it's likely that they test them to failure, in adverse conditions and trying to push the margins on weight reduction and performance.
You ultimately learn very little from an uneventful test.

>>15387492
apparently arstechnica fired Mahlmann for being a greedy jew and eric berger unfollowed him on twitter ahaha. i knew something was up when they didnt use his photos in their Starship articles

>>15387760
The attachment mechanism is different and obviously still not reliable enough.
It's further along than raptor though given relatively minor shedding we saw.

>>15387797
Just make better cameras. More bracing, more suspension, more solder

>>15387799
a little trailer

>>15387781
I'm skeptical of this argument, just because I'd expect virtually all of the debris to be pushed exactly away from the engines. I think it's more likely that SpaceX didn't want to push them too hard, since it's the only the second time firing them all together in a cluster (also note the 50% throttle static fire wasn't really close to this flight's requirements), and even a minor failure could have destroyed the rocket on the launchpad.

now back to space talk

they've got the blueprints

Do we know if the next Starship launch will be the same when it comes to not trying to get back the booster and/or the Starship? or will they try something a bit more ambitious?

>>15387937
I think it's both. UAM for getting people from suburbs to the city center. Scooters and rail for getting people to different places within the city.

Also, self driving car type shit would be hella useful on Mars.

>>15387940
its going to be similar, but the starship isnt going to have a heatshield, so the landing site near hawai is a debris field

>>15387945
Think about it though.

You could take satellite telemetry of the Martian surface, plug that data into a pathfinding algorithm, and then just tell the rovers to get from point A to point B. If you're getting stuff between different bases or to a mining/archeology site away from the main base, you wouldn't need to build roads, you'd just need rovers and the path generated by AI.

>>15387890
this is the real future

>>15387951
>archeology site

>>15387783
Yes. I would urge you to reevaluate your previous posts about it never launching and then try to learn a lesson from that.

>>15387953
Yeah. If there is life on Mars it's going to be dug deep. I expect the first colonists to go out to promising locations and dig deep boreholes to try and get samples of lower layers.

This is actually a very interesting thread
>We used steel plates for some of the Morpheus launch locations so we weren’t tied down to places with concrete. I analyzed the heating of the sheet and showed that the heat would redistribute fast enough that it would not locally melt on the surface, and… /1
>2/ …that the steel plate was large enough to take the heat of the entire launch event without melting. To be conservative (because that’s what nasa does ) we also put paint-on ablative on the top of the steel. An ablative erodes under heat and thus uses up some of the heat…
>3/ …keeping what was under the ablative cooler. (Partly we were just testing the use of ablative. It wasn’t just conservatism that motivated this.) So compare to Elon’s tweet about Starship. They plan to make their giant steel plate water-cooled. That way it doesn’t have to…
>4/ …be large enough to take all the heat of the plume without melting, the way we designed the Morpheus steel plates. For such a large rocket that much steel would be excessive. And ablative would not be enough to solve this, either. Would the ablative need to be 3 feet thick?!!
>5/ But he said it will be water-cooled, which is an awesome idea. The water will be taking heat out of the steel in realtime so it won’t melt. Simple, and it should be effective.
Theres quite a bit more.

This. All these takes both here and on twitter are worthless. You don't have the data to say very much at all.

Does anyone have that picture of all the Chinese F9/FH/SS clones?

>>15388041
Hit by debris would be the good scenario. If they shit themselves because of a reflected shockwave the cooled steel plates won't do much.

>>15388032
Delta heavy starts to outperform falcon at GEO, any mission beyond LEO and you're looking at hydrogen.

>>15388052
In that case they would need both a cooled plate and a deluge. Honestly, the actual truth of the matter is probably a mix of concrete strikes and a few engines going out on their own

>>15388046
What if the first stage was solid tho

>>15388056
with the added qualifier you're talking exclusively about the upper stage and assuming no orbital refilling

>>15388046
Sea Dragon was always supposed to be steel. The entire point was building it in a drydock like a space boat.

>>15388052
Most of the engines worked fine. Whatever went wrong can probably be mitigated. The point is we only have baseless speculation as to any root causes

>>15387725
they will have updated models by the time the OLM is repaired, but they'll still launch 9/25 anyhow
they're still going to want to do this trial suicide run before attempting a catch

>local man didn't see that chunk of concrete that was probably 5 meters in diameter almost hit Starship

>DARPA's STAR (Spaceplane Technology and Research) Space Cruiser
>The fundamental concept behind the STAR program was to maximize efficiency while minimizing cost. To achieve this goal, the craft was designed to be as small and inexpensive as possible, with only one crew member onboard. The crew compartment itself was unpressurized and only large enough for a seated astronaut, who would be required to remain in their spacesuit throughout the duration of the mission. Notably, the craft lacked key features such as hydraulics, an ejection seat, or even landing gear. Instead, it would utilize a parawing to glide back to Earth and touch down on land.
>Despite its Spartan design, the STAR was intended to function as an orbital runabout, capable of carrying out a variety of missions. The craft was eight meters in length and only a meter and a half tall at its aft end, tapering down to a fine point at its nose. To optimize its transportability, the nose was designed to fold back at a hinge four meters down from the tip of the STAR, creating a compact package just four meters in length.
>In terms of deployment, the Shuttle was expected to lift the STAR into orbit, potentially even multiple at a time, and deploy them from its cargo bay. Once in space, the STAR would set off on its designated missions, either returning to the Shuttle or making its own way back to Earth. If the STAR needed to reach higher altitudes beyond its on-board propellant capacity (which was estimated to be around 1650 kilometers), a truncated Centaur stage equipped with a single RD-10 engine - known as the Centaur-SP - could be attached to the STAR for increased thrust. This configuration would fit into the Shuttle's cargo bay, allowing for transport to geosynchronous orbit and beyond.

The performance of the launch vehicle is tonnage to orbit at what cost.
Hydrocoper thinks wet mass is relevant given a fixed upmass when it's absolutely not
