When will we try welding in space again? I'm sure we can do better now
>However, the Russian crew over-estimated their skills and under-estimated the risks. Due to their attempt at making welds in space, they nearly ruptured the life-sustaining capsule, which would have caused the death of all onboard.

>>16123216
Exactly. How tf do we intend to build real moon and mars colonies if everything has to be prefabbed on earth (or earth like conditions)

>>16123210
I think it would be a great make work activity for an Artemis mission. Bring a couple weld coupons to the moon and try welding them with various techniques. Do a few in situ weld tests and then bring the rest back for lab analysis. It's probably better to get the vacuum environment figured out with a bit gravity first before trying out 0g again

>>16123235
with Starship they could bring an ebeam welding machine to the moon and test that

It’s 6 months to mars in a starship. The average Joe would go apeshit during the journey

>>16123253
Well luckily they won't be sending average Joe for a while

bruh. there's nothing to test. you can do that right here on earth in a vacuum chamber.
the only thing that is unknown is welding in zero-g.

>>16123276

need... space butt...

>>16123268
It's more of a processes and procedures thing. Is it better to weld in the sunlight, or shadow, and how does that affect your HAZ? How do you manage regolith contamination? Welding position ergonomics with a spacesuit. Proper PPE. The list goes on. Surely there'd be vacuum chamber testing on the ground for some stuff beforehand, but that's expensive and there's free vacuum on the moon.

>>16123286
Not to mention the "make work" point. If you're sending people on multi week camping trips to the moon, they need stuff to do a little welding exercise makes for a great activity.

apparently some of you faggots think A2 is going to land on the moon so I just want to remind you that you're retarded. some of you are also newfags who don't even know how A3 is going to work so please kill yourselves
also it's highly likely the japstronauts land via the national team lander.

https://www.youtube.com/watch?v=05AQLwROFJ4

Why are the boosters and the core that roasted? The part just above the nozzle looks like it's literally on fire.

>>16123470
>WHOOP WHOOP PULL UP

>>16123475
Because it is. The hydrogen diffuses into the material, and ignites as part of the fireball.

>>16123474

>>16123475
The RS-68 pushes a lot of GH2 through the works as part of its start-up cycle. This gets burnt off in a planned fashion since you don't want to have a cloud of hydrogen sitting around the tail end of your rocket looking for a random ignition source. The orange SOFI is somewhat flammable so that scorches and the white thermal shields are probably made of some lightweight plastic so that'll ignite too under the right conditions.

>>16123475
Apparently they actually leak LH2 to help cool down shit around the rocket engines. Once the rockets fire, automatic fireball. Or at least they used to, because that was the last one.

>>16123470
Flap harder, faggot.

>>16123487
>>16123496
why don't they use sparklers to burn it off like shuttle and sls?

>>16123456
a while back I played a campaign which was otherwise stock but with the kerbol system resized to real scale. It was very hard in a fun way. Getting to orbit was a massive achievement and became routine with a low tech 3 stage rocket, and with a 4th stage it could do lunar free returns. Before I moved on to other things I was building the service module and lem for an apollo style landing and I swear it would have been 100% possible with stock parts.

Depends on how heavy they make the rovers. If a rover follows its tracks back the way it came, you could technically call it a road, but if its too havy, it may sink. But you bring up a good point. Has anyone come up with at least a concept for bulldozers and excavators on the moon? With starship we could put a cat d9 on the moon easy. We are going to need to some heavy civil work on the moon if we want to make a real colony.

>>16123545
and that's for surface. if you want to dig in that's a whole other layer of complications

>>16123547

I mean that's kind of stretching it.
but on a more serious note, there's no air friction so you can have very fast moving trains on the surface. downside is that go fast enough and you start orbiting the moon

>>16123549
You would just need a rover with a portable fuel cell or have a fab shop hooked up to your grid (solar farm you brought along in a starship)

. Today, the Orion upper stage, launched by the first Angara-A5 launch vehicle, delivered the Gagarinets small spacecraft to low Earth orbit.
The Cubesat 3U satellite was created by the Russian private company Avant Space and is intended for testing elements of the service platform.

blog post about tidally-locked exoplanets actually being quite habitable

>All about the hypothetical climates of tidally-locked exoplanets — “the popular perception of tidal-locked planets—hostile worlds split between a burning desert on the lit hemisphere, ice on the dark side, and, at best, a thin "twilight strip" of habitable temperatures in between, wracked by gale-force winds—is not a strictly impossible scenario in all its particulars, but our current best climate models predict (and have for quite some time now) that tidal-locked planets in the habitable zone with Earth-like atmospheres and quantities of surface water can more typically expect far more hospitable conditions, with comfortable temperatures and moderate prevailing winds across the lit hemisphere; that the hottest part of the planet will usually actually be the wettest; and that this habitable climate state may actually be more stable in some ways than that of a planet more like our own.”

This guy's pathologically against SpaceX and works on SLS, so I automatically distrust his choice of words when describing basically anything. Date wise, he's probably discussing IFT-2, and if he's talking about the loss of the ship, he's probably going on about the pumps and manifolds being a bit leaky with methane. Still, he may be correct describing it as a design flaw, since SpaceX is eliminating a lot of flanges and seals on Raptor 3.

Off-road camping holiday on the moon sounds comfy as fuck. Grilling marshmallows on a solar oven, anyone?

Oh, he did specify the filter issue. The only plausible thing people have suggested there is that they tap the hot exhaust from the OX preburner directly instead of going through a heat exchanger and that conversation topic's old news too.

Russia just launched space advertisement satellite

The Avant Space satellite is the first spacecraft in the future Constellation satellite system, which will consist of dozens of such vehicles in low Earth orbit and project images in the night sky. By the way, Elon Musk's SpaceX company is also working on a similar project of advertising from space.

— Our spacecraft is part of the payload of the Angara-A5 rocket. A few seconds after the launch, our vehicle separates, and then it communicates over the Crimea. This launch from Vostochny is a big event for the whole country and a huge step for us. Everything is here for the first time: the launch pad, the upper stage, the separation system and us. Our company is a resident of the Skolkovo Foundation, and we have attracted state grants for the development of a satellite and an electric rocket engine — " Anton Ossovsky shared with Amurskaya Pravda. - It is no coincidence that our satellite is named "Gagarinets" — this year marks the 90th anniversary of Yuri Gagarin's birth. This is a test vehicle, and all systems will be tested while it is in orbit.
Speaking about the space advertising project, Anton explains: each satellite of the Constellation system will represent one light point (pixel). A group of satellites will move in orbit at an altitude of about 600-800 kilometers above the planet. Their projections form a logo or text similar to a constellation in the night sky. Ads will be activated when flying over major cities and agglomerations of the world with a population of more than 10 million people. And the image size will be similar to three moons.

>>16124150
There's zero chance Elon would actually do this given the flak they got just for passively reflective Starlink satellites. But deliberate orbiting advertisements? They should burn these things down.

Nope

Why is no one talking about current starship can only put 40T in orbit when you spx fags told me it was 100-150T? Literally worst than a falcon Heavy, and im supposed to believe that starship v2 with just improvement on the raptors and 4 meter more can double payload capacity to 100T? Why vant you guys admit that this whole program is a complete failure

Now I understand why payload was a secret until it already launched. Although nothing to worry about for now. Creator of that company said that satellite will deorbit in 3 years and they will use it for testing

>>16124166
This belongs on /b/

>>16124166
Lowering vehicle dry mass will also play a huge role.
Reminder that Falcon 9 doubled its payload capacity without getting longer.
There's a lot of optimization to do.

>>16124166
Could you even fit 100t inside the current starship

>>16124178
Yes lol.
People forget that in the long run 80%+ of all Starship flights will be depot tankers.
100 tons of extra methalox is just a few meters high at 9m diameter.

>>16124166
they have just been trying to get it into orbit and make it able to re-enter, like others said there is a lot left to optimize and if raptor is still improving rapidly, starting to optimize v1 instead of just taking advantage of the coming performance improvements of raptor doesn't make sense

>>16124118
Spaceguy5 has extreme EDS and hates SpaceX so he uses his position at NASA to spread his opinions as fact.

The 'design flaw' is that Raptors deleted a heat exchanger and directly tap preburner exhaust to pressurize its tanks, this lead to some ice in the LOX tank that needed extra filters to keep from being ingested on the boostback flip.

>>16124304
It is iconic oldspace mentality.

>this wasn't how the book of knowledge told me it works so it is heresy

>>16124304
>this lead to some ice in the LOX tank
beside the filter problem, this seems to be a bad idea in general no?

>Japan is the second nation to have a man on the moon.
TENNO HEIKA BANZAI!

>>16124317
if you can just put filters so the engines don't ingest the ice and then after landing you purge the tanks with nitrogen or something, then is it?
you delete a heat exchanger and you delete the need for extra pressurization tanks
if it works its simpler (and thus probably cheaper) and also decreases dry mass
the simpler the better

>>16124402
this is explicitly a problem faced by real pressure vessels on real planetary bodies, the KSP videogame abstraction doesn't track tank pressure or calculate the crush strength of the tanks
>>16124422
No, if you've pressurized your tanks with combustion products (CO2 and H2O and CH4) and you let them sit for a while all of the H2O and CO2 will freeze out into your liquid methane, reducing the pressure
this works in flight because it's continually replenished whenever the vehicle is under load, but when it's sitting on a surface it's both under gravity load and NOT being replenished

having your pressurant condense out is bad btw (less bad in vacuum than in atmosphere)

occasional reminder

>>16124294
Elon said "flight 3 Starship could get 40, maybe 50 tons to orbit"

>>16124317
>>16124375
It doesn't matter if it's gas from the preburner or from a heat exchanger it condenses at the same rate.
Keeping your ullage gaseous is a problem they have dealt with before. For long duration under gravity you probably want to regasify with an electric heater at the same rate it condenses.

different gasses condense at different temperatures and rates, and if it's water it's going to all condense out

>>16124449
>and if it's water it's going to all condense out
Yes way before you even landed on the moon. The ratio of water to oxygen or methane respectively should be the ratio of preburner power to engine power which is a low ratio.

I already figured it out, thanks for your input

Also Starships can arguably stand unpressurized under earth gravity right now with a few dents.
In the moon with 1/6g and no wind concerns you don't need to pressure stabilize.

Imagine what you could do with the cubic kilometer of volume that just one Starship has... colonization will be a breeze with so many of them going to Mars

latest astronomer target: STOP LUNAR COLONIZATION

>Astronomers could, in just the next few years, start to solve the problem in a remarkable way: Putting radio telescopes on the far side of the moon, where the moon’s mass would block out all that electronic noise. For radio signals, it is probably the quietest place in the inner solar system. That’s in part because the moon is tidally locked, meaning that the far side always faces away from Earth.
>But even this solution has a looming problem—namely, that everyone else interested in space has thought of the moon’s potential as well. Over the next two or three years, there could well be two dozen lunar missions, some landing astronauts or starting mining operations—and all transmitting on many different frequencies. There’s something of a lunar gold rush in progress, and astronomers want to make sure science doesn’t get trampled.
>“We’ve talked about this sometimes as being a kind of Wild West mentality, a free-for-all, and we want to avoid that,” says Jack Burns of the University of Colorado in Boulder. He and many colleagues are sounding the alarm, at conferences and in peer-reviewed journals, hoping to ensure radio silence for the moon’s far side before it’s too late.

No company is going to spend millions to make shitty ads that literally 100s will see per location (at most). Especially when it's going to generate a lot of negative publicity.

>>16124510

>>16124569
Starship V2 being listed at 100+ tons in the presentation does suggest V1 might not quite reach that. Not sure it'd be as low as 40 tons but <100 seems pretty likely.

>>16124569
That's probably not true. The frostline didn't look to be particularly low.
It's just a very heavy rocket. 4mm steel plus a ton of stringers vs 0.5 mm for some balloon tanks.
They have a ton of room to optimize I'm sure they'll get to their 150 tons or so eventually.

>>16124569
they had to massively overbuild starship and superheavy due to their cost cutting causing failures

>>16124642
Well it is exactly that. There is zero chance a moon economy takes off, and lunar bases/space stations will end up being an albatross around NASAs neck preventing Mars exploration for another generation.
If an organic economy didnt take off in LEO then why will it take off on the Moon? Blue origin are actually rightwith their snail like approach from a rational perspective, because there is zero organic market to service and it wont exist for a century. SpaceX rushes because of religious zeal. Mars colonization is a crusade with no rational economic reason.

>>16124653
>an organic economy didnt take off in LEO
axiom? commercial space stations?

>>16124653

>>16124659
I know BO are incompetent and grifting off Bezos gibs, but the point is there is no reason to rush because the market doesnt exist anyway.
>>16124658
This is like crypto hype. It's all VC money or government gibs, not a real economy.

>>16124653
>>16124675
All correct.
I think it's a false expectation that companies need an economic reason to do things.
They need the economic means.
A private company can spend that profit on whatever the fuck it wants.

>>16124679
I agree thye dont need an economic incentive, but if they are doing it for something other than rational economics they need a dictator like Elon Musk. Many of us will live to see SpaceX become a for profit grift after Musk and Gwynne are gone.

>>16124675
>but the point is there is no reason to rush because the market doesnt exist anyway.
I get what you’re trying to say. BO isn’t doing it on purpose though. They’re part of the problem.
Jeff saw a slow industry and marched the shitty speed. Musk saw a slow industry and figured if he moved so much as 10% faster, took risks, and got some luck, he would succeed—and look at SpaceX now.
Jeff Bezos just purged talent from Aerojet Rocketdyne, Honeywell, and Northrop Grumman with huge paychecks and has simply been handed the baton of oldspace.
In short: they aren’t moving slow because the industry is slow. They’re moving slow because they don’t know how to do it any other way.

>>16124273
Heterosexualbros, it's so over

>>16124679
You can imagine there being a critical mass of people permanently living on Mars such that their need for goods and services creates a real space economy.
Elon wans to bootstrap that with Starlink profits.
Such an economy would then self-perpetuate unless somehow everyone wants to go back to earth at the same time.
But it for sure isn't happening on the moon that doesn't have carbon and has 2 week long nights.
Also LEO manufacturing is a stupid meme and will be unprofitable even if Starship costs 2 million $ / 100 ton and going further (the moon) becomes even more delta-v therefore cost intensive.

when can we expect another starship stacking?

>>16124694
What can the Martians provide to Earth which is valuable enough to cover the costs of the material they require? Space travel is just so prohibitively expensive that presently there is no mineral they could give us, and their economy wont be more developed than ours so they cant send value added products either. All the way up until the moment Mars becomes self sufficient it will be an economic drain on Earthers.

>>16124686
I think every good private company has a dictator and some public ones too but then they can't be unaligned with profit maxxing.
I think Elon will have no problem finding a real successor from within SpaceX that cares about the mission religiously.

>>16124698
>What can the Martians provide to Earth which is valuable enough to cover the costs of the material they require?
Only digital goods
>All the way up until the moment Mars becomes self sufficient it will be an economic drain on Earthers.
Not really true. Mars could be non self-sufficient because they don't have MEMS devices.
On earth they're neither expensive nor do they weigh a lot nor do you need a lot of them.
So you can offset their import easily. Economic self sufficiency will come before self-sustenance. At which point the Martian economy would be bootstrapped yet Mars could still die out if experiences a catastrophe.

F9 has increased commercial space activities, Starship is going to be a paradigm shift

I agree with a moon economy on the short term, but on the longer term the moon might become a propellant manufacturing site (so sending O2, H2, CH4 from the moon into LEO and other orbits), but that is still very speculative

>>16124728

>>16124880
It's not that much of a stretch. Before the H2 Japan's rockets were all licensed Thor-Delta clones or variants, and the H2's upper stage tanks were licensed back from Mitsubishi to McDonnell Douglas to be used in the 4m upper stage for the Delta III and Delta IV Medium. The H3 has the same solid/hydrolox design as the Delta IV Med, has the same diameter, and lifts the same mass. For not being an exact clone it's pretty absurdly close. The only real differences are the clustered main engines and the fact that the H3 is subcontracted out the ass.

>>16124882
Anon that's Delt IV, not Angara

>>16124892
Yup, exactly. Also SLS’s current ICPS stage is literally just a Delta cryogenic second stage. (arguably SLS is just an upscaled Delta IV in many ways) and I believe Delta CSS was actually built (or at least designed by) Mitsubishi for the United States, oddly enough.
Delta also uses legacy Titan designs but yeah, most rockets lead back to the V2 in one way or another and now I’m just going on a tangent

titan 4 rival to space shuttle orbiter as most pretty rocket ever.

>>16124913
The DCSS-4 definitely had Mitsubishi as a subcontractor. I thought that the DCSS-5 was more domestic, but I just dug up a press packet from a 2007 Delta IV Heavy launch that had MHI still listed as a subcontractor for the upper stage tanks. If that's the case the ICPS likely still has Japanese tanks.

he's actually a team lead on the HLS program, its trivial to find his real name from his username and to use that to find his job description. I know, I couldn't believe it either

Their pr video on youtube shows them making simple shapes with about 20 sats. That could easily be orbited on one launch since these sats appear to be derived from cubesats. Not sure what the market is though. Maybe the Russian gov will pay them to put a big Z in the night sky on Victory Day or something. They could also do countdowns for major events. If people see a big 9 in the night sky, then a big 8 the next day, then a 7 that's going to build interest in whatever they're advertising.
