https://spacenews.com/france-to-increase-space-spending-by-25/

France increasing Space budget by 25%, a HUGE increase coming from Europe to catch up to US or atleast not get left behind.

>>14861034
Good on France, going around the EU / ESA. Need more European nations to put stake in their own programs

>>14861006
>premade
lol
just have deployable proonter arm

>>14861006
Starship is the moonbase. Send some empty tankers on one way trips and wet workshop them.

>>14861006
why are scientists so against getting their hands dirty? send some stonemasons to the moon and build it right

>>14861060
And waste the whole rocket with the engines?
I would get this for something like the old Apollo landers, but this defeats the whole point of Starship.

>>14861041
It's going to be interesting to see where that money ends up going. A lot of it is going to vanish into their manned payload fairing idea, but that can't be all of it. There are at least seven hopeful French smallsat launchers but they seem even more doomed to die than the lineup over here.

Even with a 25% increase we're only talking about €9 billion

Granted SpaceX developed Falcon 9 for about what the projected increase in budget will be.

I found a glaring inaccuracy about the history of WWII German rocket engines that is spread across like 10+ pages. Should I create an account and try to fix it, only to inevitably be shot down by Wikipedia's retarded editor brigade?

Or should I leave it and stop being a retarded sperg?

>>14861122
*glaring inaccuracy on Wikipedia

>>14861122
Tell us what it is.

>>14861122
Create an account, and well you're at it edit Zubrin's article to include the fact that he was a literal scam artist and cultist for much of his young life.

>>14861125
z-stoff is a catalyst (aqueous potassium permanganate) that decomposes t-stoff (stabilized hydrogen peroxide).

The early "cold" engines were monoprop engines that just decomposed t-stoff and shot the steam out a nozzle. Later "hot" engines sprayed c-stoff (hydrazine and alcohol) into the hot steam exhaust for extra thrust. This weird line about early me-163s being powered by z-stoff alone shows up in a bunch of wiki pages related to the me-163 or german rocketry. The me-163 page itself is correct though, weirdly.

>>14861136
Still is. There is no evidence of him being a real engineer.

>>14861136
Robert Zubrin is based and redpilled

>>14861139
All of this aside, these engines were really fuckin' simple and I'm pretty sure you could build a pressure fed version in your garage with a lathe, a welder, and some plumbing parts.

We. Will. Inflate.
https://youtu.be/D1b3WrY9gLQ

>>14861140
There's his 1989 paper where he invents the magnetic sail.

>>14861145
Or just use a solid catalyst for a decomposed-HTP gas generator cycle and skip the hell that is pressure fed. This has the delightful property of near unlimited restarts and no need for cryogens.

>>14861154
Wow so interesting... Alright time to enter your new home, look at all that pressurized volume! It's just like the inside of that space station module you're always on about.

>>14861162

Spiders will bring about extrasolar colonization.

I really fucking hate spiders. I am not an arachnophobe -- in fact, I came up with this thought while studying one of these fuckers hanging around in the corner. They are just profoundly unpleasant to look at. Admittedly, I am still "traumatized" from the ultimate nope.exe moment of a thumbnail-sized spider crawling out of the back USB port of my desktop PC. But my (or regular humans) dislike of how they look isn't a good ethical or pragmatical reason to kill them all (it would be a bit different if everyone were a an arachnophobe).
Now space colonization enters the picture. I'd like to have my own planet without any fucking spiders. Once tech catches up to make terraforming and exocolonization as viable to a small niche interest group, as currently is, say, a reforestation/rewilding effort, people will do it for the strangest reasons. Planets were only Ancient Chinese dress is allowed. Planets were they enforce everyone to speak like a Jane Austen character. Well, things pertaining to wildlife/biology (and the uncontrollability of it) make for a pretty good case why you need your own planet.

So, the frequent question: Why would humans colonize dead planets? Because they like to tinker and actualize.


(And yes, the first sentence was just to highlight this post as on-topic. Also, I read Children of Time. Pretty decent tome.)

>>14861155
It's interesting to me that HTP rockets were never seriously pursued beyond Black Arrow. People always say that HTP is dangerous and will kill you, but I really don't think it's substantially more dangerous than working with LOX. The danger is different, sure, but not much worse.

>>14861182
https://www.youtube.com/watch?v=CB8xs8uyHLU

Reminds me of Beyond the Aquila Rift from Love/Death/Robots episode.

>>14861184
LOX is cheaper and gives better performance. If you've read Ignition!, lower freezing point was a consideration for NTO over HTP in storable liquids because they needed missiles in the deep arctic. We're only really getting civilian research into non-hydrazine storables in the past few years, and most of that is focused on N2O and some hydrocarbon (ethane/propane) for ease of handling.

so I think about going back to university, maybe for EE or mechatronics, industrial engineering if I fail at EE

>>14861136
Now you've gone and done it

>>14861298
Do it! I worked as a mechanic and then as an aerospace dev/assembly technician from when I graduated high school in 2011 until 2021 when I finally decided to give university a try again. I'm pursuing an engineering degree right now (prospectively mech/aero with robotics/mechatronics/control systems as a fallback) and it's the best decision I ever made. Fair warning though, you WILL fail some math classes no matter what path you take. I failed Calc 3 twice, actually. Everyone I know who worked in trades/industry had the same problem when they went back to school... once you stop using math regularly it takes a long time for your brain to remember how to learn it. Stick with it though and you'll thrive. Universities are really lenient with ""adult"" student admissions because they know that even if you struggle, you're not gonna quit.

>>14860994
I haven't been on here in weeks, are they testing the booster soon?

>>14861332
They did 7 engine static fire yesterday, was like 10 seconds

>>14861332
Basic 7 engine static fire is finished.

Now they will retrofit the B7 with some new upgrades and then roll back out for 33 engine static fire in ~few weeks.

In the meantime, B8 rolls out for testing campaign.

>>14861334
>>14861340
Nice, had a look and saw the webm on the previous thread, didn't look like there were any problems either

>>14861349
Yeah, chamber pressure on all 7 was good

>>14861340
I actually don't think it'll take too long to retrofit B7. Elon said "robustness" upgrades, so I assume the main upgrade he is talking about is the new raptor engine shields they've been testing in mac gregor. Shouldn't be too difficult to add them to all the engines.

Apparently the tile loss on S24 after the 6 engine static fire was most likely largely caused by concrete shards blown up into the sky striking the ship.

why is the perseverence moxie experiment such a big deal? it's such a basic bitch science experiment. like no shit, of course you can make oxygen from CO2, it's trivial to do it on earth. do people think the laws of physics work different on Mars? are there any anons here that can vouch for moxie? it seems like a huuuuge waste

>>14861267
I'm an SE but I study physics in my spare time

>>14863086
Was it a ton of money for something trivial? Yes. But you and I can’t stop the fact that it was already designed, built, and launched. It’s out of our control and it’s already on the martian surface so it’s best to look at the upsides:
• the first experiment to ever extract a natural resource from another solar system body and turn it into something else
• it worked more efficiently than expected (a much better outcome than ‘ummmm something is wrong tee hee’) [see: drill core and cache program]
• it is being tested in a different range of conditions including night, day, high dust storms, colder than usual days. It has worked great in all of those so far
• if anything it is a proof of concept, something nice to see before you launch humans there who will NEED that technology to work. Not so fun to wing something with actual humans and find out all your theory doesn’t work in practice and now you have a couple of dead apes on the martian hellscape stuck with no breathable air

>>14863100

By extension nor can falcon 9, and yet kplo is trucking its way there as we speak

Neither can SLS Block 1. Falcon Heavy will be launching Gateway and the first few resupply missions.

>>14863154
Repuhrashuns

>>14863174
What amount of payload would you define as "significant?"

What's the point of launching a space station to explore the moon? Wouldn't it make as much sense to set up some kind of vanguard FOB on the surface? If you use rockets to hop from area to area, then no matter what you still enter lunar orbit and have to land/dock. At least on the ground you have the whole moon covering your ass from space debris and access to local selenology/life support resources. The only advantage to be seen is more consistent solar power

>What's the point of launching a space station to explore the moon?
Political. It's quicker to make than a ground base, and this would force the next governments to not cancel support for the station.

>>14863182
Hardly a significant mass. The earlier anon was saying we'll have a hotel on the moon in just a few years.
>>14863184
That's my point. FH can't and neither can SLS. So something else must be able to according to anon.

>>14863188
A mass large enough to facilitate the construction of a hotel on the moon. Not a lander, but a hotel...which is what retard anon is saying will happen within a few years.

>>14863216
I hope so but currently unproven therefore not something we already have. But that aside, assuming it can, it's not enough to build a hotel on the moon before the end of the decade.

We'll be lucky to see a single human in the moon by 2030 yet people think we'll have an operating commercial hotel there. It's not going to happen.

But fuck I truly hope I'm wrong. But given there has been zero demonstrated progress with heavy lift platforms in the past couple years I just don't see it happening.

>>14863271
If the interior of Lunar Starship is remotely close to Dragon's you've got a gargantuan space hotel in every way besides the way it's used.

What? So they'll blow it up with no survivors if it can't perform the landing burn?

>>14863202
>the worst timeline
NASA is incapable of beating SpaceX to a manned Mars landing but a large SEP tug opens up a lot of possibilities, a Mars and Venus flyby mission is just one. It could for example put serious payloads in the orbits of Venus and Mercury, or perform a manned mission to Vesta, Ceres, or a number of other asteroids, or send probes on a very fast trajectory to the outer planets. SLS is only needed to launch Orion if there isn't a true replacement for it by that point.

>>14863193
>What's the point of launching a space station to explore the moon?

SLS cannot deliver a lander directly to the Lunar south pole.

>>14862654

>>14863314
Yeah but let's be honest, starship is going to be ready to land humans, especially paying customers, on the moon before 2030.

They're not even close to having it land properly on earth, they're a long way off getting into space, let alone LEO, and from there it's a fuck tonne of work to get it reliable enough to go to the moon. They haven't even got to the point where they can start testing refueling in orbit.

Where's the economic incentive for a hotel on the moon within 8 years when we can't even escape LEO yet.

>>14863442
Isn't, not is.

I don’t think this will satisfy you, but for the sake of argument let’s say Relativity’s printer tech matures even more. It doesn’t even have to be from relativity-I’m just using them as an example because their tanks seem pretty nice visually speaking and don’t look like doggy doo slop like other printers
Anyways let’s say metal printing tech gets to the point where it can print pretty much anything so long as you feed it spoil—and can do so even in a vacuum. Well all you would need to do is land a bunch of printers and spool on the lunar surface. Not hard to do with a FH. Land a couple of them there, print giant structures or print prefabricated parts and build up structures. That doesn’t seem out of reason to me
My question has more to do with oxygen. Aside from bringing it from earth how the heck are you going to ISRU oxygen on the lunar surface? I guess technically ice, but do we even have a confident guess as to how much is really on the moon and how accessible it is?

>>14863603
You're correct that it doesn't satisfy me in so far as it'll never happen by the end of the decade. The biggest thing with that is you still need to take the mass of the spool with you, so why not just send parts to build a hab instead of the raw materials?
I think realistically long term the ISRU will have to use the regolith to create the outer shells of hand. Either that or a empty lava tube if they chose a site near one. Though that has its own issues.

As for oxygen and other resources. I haven't really looked into that as much as I wish I had but you'd probably enjoy this book. Covers a lot of these topics in depth.

Ignore the orange rocket bad and follow the links.

Are they tanking SLS for YET ANOTHER fucking test? I thought they could only put fuel into that big orange fuck like a dozen times or so, aren't they already close to the limit after the two green runs and all the subsequent tanking/detanking/scrubs?

eh, at this point it's whatever

>>14863929

>Neptune captured by Webb’s Near-Infrared Camera (NIRCam)

IT'S FUCKED AGAIN

>>14863941
They still need to learn how to fuel it without it leaking. They haven’t done that since it’s just sprung a leak in the exact same way as last time. Also they never learned in the past with all of that shuttle heritage hardware since the shuttle leaked like a sieve and scrubbed constantly.

No one knows if they’re near their limit for rankings since no one knows just how many more times they can get new recertifications, just like with the boosters.

birds more interesting than orange rocket

>>14863980

>>14864007
Soyuz has the strongest classic car energy of any rocket currently flying.

>>14864062
SLS failures are due to incompetence not the inherent difficulty of rocketry.

If private rocket companies around the world can put fuel in their rockets then NASA should be able to.

>>14864057
>ask if people are watching a stream

>>14863968
>No one knows if they’re near their limit for rankings since no one knows just how many more times they can get new recertifications, just like with the boosters.
The boosters are already 'expired', I'd be surprised if the big orange tank wasn't also at limit and that's why it keeps springing leaks. The shit is just going to get more brittle the more times they do this, fuck me SLS really is going to RUD if they try to fly it.

>>14864115
They’re expired but NASA decided to change the expiration date, twice. If they don’t get this fueling problem fixed they’re going to have to do it again. I’m pretty sure the current problem is something related to the quick disconnect plate on the LH2 line attachment, not something related to the booster itself.

Those problems come later.

>>14863980
Sorry bro, we were all watching it in Clear's channel.

SLS SRBs static fire imminent.

So basically, they didn't fix the problem but found a way around it.
Now, I'm no rocket scientist, but having H2 leaking everywhere can't be good.

>>14864401
it's leaking way below the conservative limit. there's nothing to worry about there

>>14864401
They just said the seal behaved as expected, increased pressure, decreased leak

So previous seal was fucked

These AI pictures are getting weird. I know that was Falcon Heavy.

>>14864403

Hopefully it's reliable, but the problem is still there.

>>14864403
>>14864404
Maybe next time they do the same and it doesn't work

>>14864409
>but lower than last time
I thought it was higher, since they said they would be increasing the pressure of the storage tank and apparently that was enough to get the seal to conform around the line more

>>14864416
Nah, it was lower.
Maybe the high kick made things worse.
Anyways, we still have no clue what's happening.

>>14864419
It was higher, even NSF just repeated it

Will it be better for SLS to succeed or fail?

>>14864420
Ok, maybe I heard it wrong
Doesn't mean the problem goes away

>>14864423
Well apparently this is how the seals were supposed to perform in the first place as the NASA guy said on the last update

https://twitter.com/SpcPlcyOnline/status/1572641368488681472

Nail: good news from hydrogen team. Leak reversed its trend. Leaked less with more pressure. That's what it's designed to do. Both Core Stage tanks in replenish and stable.
Now will load upper stage and then do Core Stage pre-press test-- raise pressure to launch readiness.

>>14864422
