Looking over the list of Zenit launches, they had first stage engine failures at 3, 3.9, 4.5, 48 seconds. None of those would have been great, but I'd take shutting down a booster and limping into a safe abort zone on the other three over having to deal with a SRB that decides to get unruly.

I remember reading some paper from early 2003 (like just after columbia, it clearly wasn't edited for it) that compared the Orbital Space Plane programme with early 1970s Office of Management and Budget (OMB) scope statement for the shuttle, they didn't want NASA to spend too much on the shuttle so they proposed a smaller one, <14 tons payload. Anyway that paper compared the political, technical, economic situation, interagency relations and concluded that the OSP was not going to achieve anything without learning from the lessons of the shuttle and OMB's proposals.

But yeah, it wouldn't have been pretty, COTS would have no chance of happening, NGLT and OSP probably continues through the decade until 2009 when recession + obama getting elected cancels it.
By 2010 it's like IRL except no Dragon, no F9, no Antares, no SLS or Orion on the horizon, and the shuttle probably keeps flying until the late 2010s. The "good" side is that the gap in crewed american capabilities will probably be shorter.

So the goal of Artemis is to establish a sustainable moon base, right?
But we have always known that the SLS would be way too expensive for any kind of sustainable moon base with NASA's budget.
So in the end it will fly a few times to plant a new flag and then we will have to wait for them to switch to Starship anyway to bring the costs down before actually establishing a permanent presence.

I haven't followed space flight in a while so please correct me if I'm wrong for having a very bad impression of SLS.

>>15165704
The goal of SLS is corporate welfare for the business friends of Washington, distributed thickly across all fifty states. This was the aim of the program when the specifics of it were hashed out by congressional aids back in 2011. NASA is using it because they legally don't have any say in the matter. The funds were allocated with specific directions about how they were to be used, and NASA can't tell the government to fuck off, because they're a government agency themselves and most government agencies have to start hopping when congress says Jump.

If you have a bad opinion of SLS that just means that you're reasonably well informed about it.

I think space solar could be a big customer for starship.

You have to think like starlink, it's initial goal is not to compete with grid energy, but to provide energy off the grid.
You can get really out of the box with this as well: electric drones that can fly, sail or crawl indefinitely without having to carry heavy batteries or rely on intermittent solar power.
Powering laser thermal craft or dark side bases on the moon.
Providing power to other satellites in orbit.
Enabling very low orbit satellites etc.

I think space solar is gonna happen for the Moon before it happens for Earth, because the minimum scale before there's a measurable benefit is much much smaller for Lunar ops than it is for Earth civilization.

>>15165835
Pretty much, technically means you could have a satellite that doesn't require propellant at all to stay in orbit, just power.

Tunnels will be a major part of any infrastructure on any worlds we build settlements on. Check out this video->> https://www.youtube.com/watch?v=htVqxyyFoVo
It's extremely impressive to me how much shit is going on to produce this tunnel and presumably the other modern tunnels we have in the world, but how are we gonna replicate this on Mars or the Moon? There's got to be a simpler way to accomplish the construction of a long underground tube without risking catastrophic failures.

>>15165890
Funny - I just watched this video yesterday. Tunneling on other bodies will be easier in that you don't have to worry about rowdy hydrogeology as much. Their video for the pumped hydro plant made me respect the complexity of tunnel boring machines a lot more.

https://www.youtube.com/watch?v=6AV2NcyX7pk

>>15165890
Why else do you think the Boring Company exists?

>>15165890
we will inhabit the caves

>>15165890
I worry that the low temperature of the martian surface will make tunnels difficult.

Like, if the ground is minus 70 and then the inside of the hab is 70 degrees, you're going to either destabilize the soil by melting water/releasing CO2 or you're just going to run out of energy to heat everything.

>>15165914
I looked into this, it gets warmer the lower you go

https://vocaroo.com/13H6sQkV4DRX

>>15165914
Watch the videos. They explain how they fill voids and deal with water inrush with injected resins and concrete.

Do you guys think horizontally landing liquid flyback boosters could have worked? How would you make a fully reusable vehicle with these without horrible payload penalties?

>>15165922
the weight penalty would've been lower than the Shuttle upper stage for sure. Not to mention that having a higher fuel fraction is more important for the second stage

>>15165922
They would have worked because you were only looking for ~10T to orbit max and you don’t give a fuck about mass penalties

>>15165922
The big advantage is that you don't need throttling capabilities and/or a large number of engines, you can just put a few big, already proven engines on your fly back booster and that's it.

Since Throttling is not something you can usually easily add onto preexisting engines, that matters.

>>15165337
They need to stop dickteasing and launch that fucker already.

>>15165919
This funny, it's educational

>>15165918
Interesting. How deep until you get to habitable?

>>15165923
That doesn't stop the basic problem of heat flowing back into the rock though.

>>15165746
Kek my friend
which samples did you use?

>>15165922
It could have worked, even if it would never have worked quite as well as VTVL design. If you wanted a fully reusable evolution you'd need to go with one of those spaceplane-riding-a-spaceplane proposals, but that's going to be even harder to perfect than a fully reusable Falcon 9. It was a viable idea and there was a time where it could have out-performed conventional expendables, but it's not going anywhere now.

>>15165937
The rock becomes water tight so that the liner can be installed. Again, watch the video.

>>15165606

>>15165944
It doesn't matter if it's water tight if it's thermally conductive though.

>>15165949
If you're talking about pure thermal losses, that won't be a problem. If anything, heat rejection will be the main issue. In the case where habs are bleeding heat, waste heat from thermal processes (chemical, metallurgical, power generation) would be enough for district heating.

Heat "losses" go towards warming up the surrounding bedrock and resulting in less and less heating required. Eventually the system can reach a thermal equilibrium where the basic activity where people move around is enough to keep the habitat at a comfortable temperature.
As for the melting and shifting of ice, there's no ice in solid bedrock, and even if a deposit of ice is found, that's what reinforcements are used for. You excavate a hollow to remove as much ice as you can, then backfill with dry tailings, then inject a binder to cause the whole mass to harden into a single big lump.

>>15166449
Why not?

>>15166454
Why it won't be required? Because the launchpad was designed with not needing a deluge in mind.

In theory, with FireX and a good layer of Fondag on the ground it should be more than possible for it to handle the launch thrust without breaking apart

tunnel segments can be made from sulphur concreate reinforced by basalt fibers
lower gravity means you need less material and it's easier to manipulate these blocks
seams or cracks can be made airtight by simple blowtorch + pressure
or you can spray epoxy resin to seal it

>>15166544
basalt fibres are actually amazing material that doesn't get nearly enough credit
they are almost as strong as carbon fiber and all the materials you need to make them are are suitable rocks and electricity/heat to melt them
you can make almost anything from that - rebar, ropes, fabrics, insulation, fiberboards, filtration media
https://www.youtube.com/watch?v=KORpVO7-LJ0
and importantly, unlike carbon and asbestos they aren't fine enough to breath in, so they are completely safe to work with

SLS is arguably his brainchild and the fact that he is content with it just flying crew and leaving pretty much every other aspect of Artemis to SpaceX while still speaking highly of them is really good.

If i have a mixture of a heavy gas and a light gas, for example nitrogen and hydrogen, will the average kinetic energy of the hydrogen molecules be the same as the average kinetic energy of the nitrogen molecules?

So is the “only 5 flights a year allowed by FAA” thing true

>>15167015
Only from Boca Chica. They have approval for 24 per year from the Cape right nos

>>15167019
Is that open to being extended to pretty much infinite flights from texas, or is 5 the best they’re gonna get without the oil rigs

>>15167024
i don't think its impossible to have more than 5, probably have to amend or redo some enviromental stuff though
I think its more about politics, at the end of the day who gives a fuck about some random strip of beach? there are plants and animals everywhere

>>15167024
Texas is a test site, on a public highway to a beach (a beach in Texas), AND a wildlife preserve. They're not getting more.

>>15167024
The only reason they'd go over 5 test flights a year is if they get to the point where they want to do e2e from boca chica to canaveral in which case they'd need to get permission from the FAA to go over, but if we're at that point then the hardware would be extremely well tested and permission shouldn't be hard to get.

They had a decade to do something cool and they didn’t.

Actually, they did cool stuff, but they never found a way to really make money other than lunar lander constests. Maybe SpaceX choosing to build a rocket first, then make it reusable, was the right course of action desu

> But Xombie also highlighted Masten’s weaknesses. The company would hire people, teach them about every part of a rocket, and then watch them leave because Masten didn’t pay them enough or they couldn’t stand living in a remote town in the desert. Brockert, Garcia, and a Masten intern named Mike Judson all eventually moved to Astra Space, a rocket maker that recently reached orbit. Another intern, Tim Ellis, went to Blue Origin and later co-founded his own company, Relativity Space, which is using 3D-printing technology to build entire rockets. Goff also left, in 2010, to start Altius Space Machines, Inc., an aerospace company.

> But then Covid hit, and Masten started announcing delays to the project. The pandemic-induced supply chain issues blamed for the slowdown forced the company to manufacture parts in-house that it had expected to buy. As costs rose, Masten started burning through cash at an unsustainable rate. It tried to raise money from investors but could find no takers. In July it filed for Chapter 11 bankruptcy protection. It either laid off or furloughed the majority of its employees, leaving at least some possibility of a last-ditch comeback. Better-funded space startups are now in the process of assessing Masten’s assets to see what they might buy.

Seems like Masten just didn't accomplish much on the commercial side and eventually ran out of money, not sure if they actually tried to build a vehicle

>>15167206
Even by 1987-1988 internal western military planning and budget began to envision a military downscaling since they concluded their armies were safely superior to the soviet one and the risk of war was negligible with Gorbachev in power. That's why the general military downscaling was so quick after the fall of the berlin wall and the withdrawal of soviet troops from east germany.

Each capable of launching with 100 fobs missiles and each Starship with a 1MW pulse laser system that fires for 0.1 second bursts (vs the conventional 100kw that fires for 2-5 second) with 200+ km range. Each Starship would also carry 100-1000 ICBM warheads to destroy conventional ground targets.

>>15167263
I can easily see 100 Starships in service in just 4-5 years. If they can produce one starship every month per build site, that means 24 in one year, 48 the next, and in 5 years, 120. If they scale up their starship output even further by adding another line to increase production on both sites by 50% each, that would bring production to 18 per build sites. Or 180 in 5 years.

>>15167038
>>15167076
>>15167103
What the fuck is wrong with you.

>>15167276
I did a rough calculation yesterday on the amount of food needed for colony of 100 to survive 5 years on Mars. Its a single 150t Starship full of prepackaged food that they eat on ISS. 5 years 100 people with 1 Starship. Thats assuming no growing of food on Mars. We can optimize it further by using dried foods/etc and doubling/tripling food capacity on Starship with use of mass efficient packaging materials. That can extend the food capacity per Starship per 100 people from 5 years to 15 years. 2 Starship will given 100 people on Mars the ability to eat Earth food only for 30 years.

>>15167259
looks like baltimore

>>15167281
A rough calculation by NASA is that one astronaut needs 1 ton of food per year. So a colony of 1000 people would need 1000 or so tons of food, assuming no crops, which is “only” 8 or so starships.

Assuming a cargo starship needs 6 refueling a in LEO, that’s 48 starship launches a year to support a colony of 1000 people on Mars . Stuff like water, air, etc. can easily be made by ISRU

>>15167294
Wait I fucked up my math. That’s 7 Cargo starships, and 42 tankers. 49 Starship launches per year, sorry.

10,000 people on mars would need 490 Starship launches a year, or 3 every 2 days. And 20,000 people on mars need 3 launches a day, which is SpaceX’s current goal with Starship

But you can only send ships every 26 (?) months, and even if they're coming back it's like 18 months to a return synod, so you have to multiply that by at least 1.5.
At least at first, before they start sending humans, they can fill up the first flights with food and other supplies so there will be plenty extra when they do send the first humans.

Kinetic/explosive projectiles are an easy way to get everyone to hate you in space, because it creates high speed mobile debris fields that fuck up ships, planets, and satellites. This is the scenario regardless of hitting or missing the ship. It's not an issue on earth because the gravity makes everything stop shortly after but there's no such force in space.

>>15167438
Possibly, there's a road closure and static fire is the obvious next step in the testing campaign. That, or S25 cryo which isn't a priority now.

>>15167557
Winds. Airships are highly sensitive to winds because they fly so slowly. The headwind penalty is nonlinear with wind speed. To cope with this, you may want to increase design cruise speed a bit over what you would have naïvely chosen. You’d burn more fuel in still air, but you’d burn less when you faced significant headwinds.

The other approach would be to take a deliberate strategy of riding the winds. With real-time wind data, it should be possible to plan a route that uses winds to minimize fuel burn and increase overall performance. It would be bringing a form of sailing back, only using tons of atmospheric data and autonomous route planning to do it in modern style.

A successful system for optimizing for winds would have a large benefit and could be a game changer.

You could probably fill up the entire cargo section with raw metal at that point

>>15167654
So I get that SS has shown that welding sheets is still better than printing metal a la relativity, but in terms of getting the most raw material to space per launch is it better to fling up a bunch of sheets, or fling up a bunch of spool that feeds into an off-world printer that then prints sheets or parts? I feel like spool would pack way more dense than large sheets ever could

>>15167692
No way an expended upper stage costs multiple billions. JWST cost 9 billion, if you could fly a comparable decadel level project on an expended Starship there are absolutely worlds where that works out to be cheaper. I don't think /sfg/ understands how trivial launch costs are compared to development and integration costs. If you wanted to launch a Uranus orbiter and probe, an expended upper stage is the kind of thing that would be on the table if you really wanted easy nice to haves, like a direct trajectory and a huge fixed dish.
>Although the SLS is only confirmed for use on the first few Artemis missions, several NASA mission concept studies for robotic missions considered launching on the SLS. These include: Neptune Odyssey, Europa Lander, Enceladus Orbilander, Persephone, HabEx, Origins Space Telescope, LUVOIR, Lynx, and Interstellar probe.
Expended Starship obliterates SLS at a fraction of the cost, even with EUS and next gen boosters.

>>15167689
if you expend both the booster AND starship you can get 1000 tons

>>15167689
Couldn't they expend older Super Heavies like they do with old F9 boosters?

If they actually go ahead with their launch cadence and mars plans, they will likely build thousands of upper stages, maybe 10 or 100 times more upper stages than lower stages.
Ultimately the booster flies back to the launch site in 10 minutes.
Meanwhile the starship might spend hours or even days in orbit, and the starships that go to mars will be gone for over a year.
Booster build rate will be very very low compared to ships, so it makes sense that they wouldn't plan to expend them.
If they do it would likely only be for very special one-offs.
