>>11304621
>I read somehwhere they are going to make a falcon9 clone?
You mean this? It does seem to be like a Falcon 9 except it would be designed from the beginning as a reusable rocket rather than an adapted expendable one. That would be an improvement, hopefully it goes well for them.

I forgot about the two Lunar Gateway modules their going to build:

>The European System Providing Refueling, Infrastructure and Telecommunications (ESPRIT) service module will provide additional xenon and hydrazine capacity, additional communications equipment, and an airlock for science packages. It will have a mass of approximately 4 t (8,800 lb), and a length of 3.91 m (12.8 ft). The studies and design are being performed mostly by Airbus and OHB. The module construction was approved in November 2019.

>The International Habitation Module (iHAB) will be an additional habitation module built by ESA in collaboration with Japan. Together with the HALO module, they will provide a combined 125 m3 (4,400 cu ft) of habitable volume to the station.

Their also working on a large, robotic lunar lander and of course their also building the service module for NASA’s Orion capsule.

They made a prototype tank for the Starship and it‘s strong enough for them to go back to welding prototypes after the last prototype blew up.

Crew Dragon launch abort test this weekend. After that they‘ll fly humans.

Starlink launches every other week or so now. They‘re cranking out 7 sats a day or so. Final constellation is gonna be tens of thousands strong.

Boeing Starliner missed its orbit during its testflight because the clock didn‘t work right. They did most tests, but couldn‘t test docking with the ISS. Question is now whether NASA lets them proceed with people regardless.

Electron is investigating reusability and telemetry data says it should be doable.

Blue Origin is working on an actual factory and launch pad for New Glenn now.

Orange Rocket core stage is done and preparing for green run this year. They also tested a tank to destruction and it worked well.

There will be a dating show to determine a woman who will fly with Dear Moon.

Also China successfully flew a Long March 5 again and they‘re launching a shitton of stuff in general.

What is it about pictures from space that make them look so fake? (pic rel)

The ISS pics and the recent Starliner footage don’t look this way.

>>11305041
yeah wtf???? how could the sun be lighting up TWO things at the same time

>>11305041
Part of it is that there's no atmosphere in space to scatter some light, resulting in harsher and less "real looking" shadows. Look at a CGI render without shadow softening and then with softening and you'll see what I mean.

>The ISS pics and the recent Starliner footage don’t look this way.
Different cameras and exposure settings can lessen the effects of harsher shadows. Also, some images for public display could be edited to look better.

>>11305041
there's no atmosphere to make them fuzzy

>>11305051

And to use labs across the country to analyse the evidence. The investigation is expected to take a couple of years and a merely a few billion dollars to make absolutely sure we know what happened. Don't worry, no key managers won't get fired, we don't want to disrupt American space flight and the money it brings to key states.

Earth isnt a perfect sphere by a longshot

The thing that disappoints me about space is that, unlike every other technological revolution- space requires a lot more capital to startup.

Unlike with industrialisation, computers or the internet is it even realistic that a person with a great idea could have a startup? It’s disappointing because everyone will have to go through the big well-established corporations. The only other way is to be extremely rich beforehand
People with the best ideas will still have to waste time wagecucking their way up the chain before they can do anything- it sucks

>>11305560
That's why lowering the cost to access space is such a big deal. If getting to space is cheaper, then the capital required to do the amazing space projects lessens considerably.

>>11305565
Still, what if you had the idea for the airships that go high altitude and then boost to orbit- you can’t utilise the cheap costs of rockets or anything then (maybe the boosters I guess).
If you laid out the basic design and idea, but didn’t have an enormous amount of capital- this idea could never come to fruition. That’s just how it works I guess, but it’s still sad- makes me less excited about any work I could possibly do without becoming rich off something else first

>>11305576
I realise you could take these ideas to big corp, but that sucks as well. It’s great way for these ideas to be done poorly and for the inventor to get ripped off in the process

>>11305041
>What is it about pictures from space that make them look so fake?

It’s a very different perspective from anything over 99.99% of humans have ever seen first-hand.

What’s the appeal of engine clusters over giant ass engines? Is it just because people don’t want to bother designing, engineering, and constructing a whole new size of engine when they can just reuse existing ones?

>>11305602
people only pick giant engines because they can't be bothered to figure out how to plumb up the objectively superior engines

>>11305602
Multiple engine-out redundancy. Easier to build and maintain.

Nah. If you think spacesuits for example are solved, just look at what they are coming up with. Apart from that I'll bet there are innumerable bits of tech that are currently bespoke that are ripe for turning into commodities. I'm sure in future you'll be able to put a rocket together with COTS components. Software is another area.

They said that same thing the last two decades an it never happened yet

>>11305560
Also as they say, good ideas are plentiful, it's execution that's the hard part. Someone charismatic and determined will have a lot more luck attracting money and perhaps that's more critical than a good idea. Thousands of smart well resourced people have been pondering the physics and cost of various launch options for decades. It's unlikely that there's much low-hanging fruit ideas wise. What Elon did wasn't a new idea - it was just successfully executed. Note I'm not putting him down, as there's certainly genius involved in pulling it off.

Why exactly is the James Webb telescope taking so goddamn long? They started that project shortly after fucking Doom came out.

>>11305859
Government

>>11305869
Government can do shit fast if they want. The Apollo program took about nine years to put people on the moon and when they did so, they did it six times in the space of four years. Putting a telescope in orbit isn’t even treading on new ground like Apollo was, so what’s the bother?

>>11305878
>Government can do shit fast if they want.
Why do you assume this? Moreover, if this is true, then what can you extrapolate from the fact that it is not going fast?

>>11305878
>Government can do shit fast if they want. The Apollo program took about nine years to put people on the moon and when they did so, they did it six times in the space of four years. Putting a telescope in orbit isn’t even treading on new ground like Apollo was, so what’s the bother?

Not nearly as much money, priority to deliver in a given time frame, and less concurrency in addressing the known unknowns. There was a lot they just did not know how to do when they set out to do it.

>>11305878
It's almost like someone figured out that by putting all our eggs in one ridiculously expensive and precious basket, they could string out the derisking process for decades

>>11305859
The first batch of delays from 1996 to 2010, were due to many reasons: technology to make it feasible not yet existing, multiple design and dimension changes, naive underfunding, contractor mergers etc. JWST didn’t really exist as anything more than a expensive study until 2011, when they did the critical design review and started production of the mirror segments. All segments were finished by 2015 and the mirror was assembled by 2016. Next, both the mirror and sunshield/vehicle bus segments underwent extensive testing and in 2017/2018 several major technical faults were discovered in the deployment process. This caused the launch to be delayed to 2021. Since then Northrop (main contractor) and NASA have successfully corrected the technical faults and mated the two segments, finishing the spacecraft’s assembly. JWST is currently undergoing final testing before being shipped off to Guyana in preparation for launch next year.

>>11305898
Well that’s good I guess.

And, here you get an informed response:
>>11305898

>>11305859
Neither the government, nor most of the people in charge of the project, nor those making JWST care about what it will do. They just care about making the payments last longer.
The longer they delay the more money they get. That’s it. See boeing and whoever else is making the SLS. It was subsidy farmed for years until they started having o make progress since spaceX started running rings around them.

>>11305576
So in plain terms: you are upset that you cannot bootstrap a space business. Honestly, if you look back at history you'll see that the individual visionary that bootstrapped from nothing is a meme. Most inventors were of noble blood to start with, or had benefactors, or worked with the military (even thousands of years back), or raised seed capital in one way or another, or just worked phenomenally hard to raise themselves up.

For example...

'George Stephenson (9 June 1781 – 12 August 1848) was a British civil engineer and mechanical engineer. Renowned as the "Father of Railways", Stephenson was considered by the Victorians a great example of diligent application and thirst for improvement.'
'He was the second child of Robert and Mabel Stephenson, neither of whom could read or write.'
'he was illiterate until the age of 18.'
'In 1801 he began work at Black Callerton Colliery south of Ponteland as a 'brakesman', controlling the winding gear at the pit.'
'In 1811 the pumping engine at High Pit, Killingworth was not working properly and Stephenson offered to improve it. He did so with such success that he was promoted to enginewright for the collieries at Killingworth, responsible for maintaining and repairing all the colliery engines. He became an expert in steam-driven machinery.'
'As the L&MR approached completion in 1829, its directors arranged a competition to decide who would build its locomotives...Stephenson's entry was Rocket, and its performance in winning the contest made it famous'
'The promoters of the [Leicester and Swannington Railway] line Mr William Stenson and Mr John Ellis, had difficulties in raising the necessary capital as the majority of local wealth had been invested in canals. Realising the potential and need for the rail link Stephenson himself invested £2,500 and raised the remaining capital through his network of connections in Liverpool.'

etc...

>>11307000
Private launches are not public customers. They're private customers.

>>11307014
I might have mixed up my terms. What's the difference between public customers and private customers?

>>11307017
Scale/numbers and ease of availability. For example, Tesla cars while they are bought by private individuals are public. However if Lamborghini sold a $1 billion dollar car to 5 private customers, that's not public. Similarly, if SpaceX is offering launches to couple dozen private customers, its not really a public offering. If SpaceX offers services(Starlink) to 1 million customers, that's public.

Speaking of, I hope everyone gets on reusable rockets, especially NASA after Artemis is all said and done.

>>11307160
After SLS is retired or Shelby dies/retires, NASA will finally move on. Right now, its an old baggage.

>>11305602
Larger engine nozzles are more prone to combustion instability. And like >>11305604 said, the process of designing, testing, and redesigning the fuel injectors for an engine of large size is stupidly expensive. It's the reason the Soviets bolted 30 engines to the N-1 rather than create a huge engine like the F-1 on the Saturn V.

>>11307226
actually what I said was that smaller engines are objectively superior on all of the metrics that matter:
1. Thrust to weight ratio
2. Thrust to area ratio
3. Thrust to cost ratio

>>11307226

NASA has reusable rockets. NASA is the national space agency, it can use all of the American commercial rockets, and all the American commercial launchers are American rockets. SpaceX rockets are theirs to use. NASA does not need to have "its own".

>>11307352
incorrect, NASA can ask SpaceX to submit a bid for space launch services but SpaceX is under absolutely no obligation to provide them

>>11307358

As a commercial launch services provider they and others are eager for NASA's business and willingly wish to have it, so that is seldom or unlikely to occur to matter.

You’re not thinking of the idea in the right way. Think of it this way.
Let’s say constructing a car takes seven days.
If you have only one assembly line going, you’re making a car every seven days, but what if you had seven cars undergoing construction at any time?
That’s a car a day.

>>11307525
starlink is probably going to mint money. He'll have tens of billions of dollars a year coming in from that, has experience tooling assembly lines and in mass manufacturing satellites. It is ridiculous, but so was propulsive landing of a rocket booster. He can do it, or get quite close

>>11307542
Pretty sure 14,000 tonnes of ship is harder to put together than two steel barrels weighing a few hundred tonnes each, especially once a lot of the welding is automated.

>>11307547
I know. I guess he's just going to expand out of Boca Chica village towards brownsville like some sort of fungus
>>11307548
if Starlink makes as much money as we think it should he's going to be the richest man on the planet

>>11307551
It's probably going to stop short of the gorillions of dollars most people think because there will be a lot of lobby money by telcos and many countries will flat out ban it. But yes, even with those limitations it will take money in hand over fist and fund a massive starship fleet no problems.

>>11307548
Starlink will still need ground stations to work. Anyone claiming that you'll be communicating directly with the satellites on a consumer mobile phone is deluded

>>11307556

You're implying that he's going to "mint money", which won't happen if the coverage is limited by ground station coverage.

I don't think the problem with any of those three is that they're rich, it's the things and people they all stepped on to get to where they are. Musk steps on his team a little bit by burning them out but I don't see it as the same thing qualitatively as the other ones

Basically yes. What do you think you're going to do in a place where literally everything is owned by The Great Elon end even the air you breathe costs money.

>And, here you get an informed response:
Thats not an informed response, its a collection of excuses for the consistent failure of a project that is now a decade and a half behind schedule and 12.5 billion dollars over budget. Because its being placed in an orbit that prevents servicing missions there will be no fixing it after the inevitable mistakes and overlooked factors are discovered post-launch. JWST will never deliver data or anything of value, but thats OK because they're just planning to use JWST to study nonexistent dark matter anyway.
The original HST was started with a cost estimate of $400 million and a proposed launch in 1979 ended up being 5 billion dollars and launched in 1990. What good has it done for anyone? What valuable discoveries have the users of HST produced?
Interpolating between HST and JWST, you can expect the next space telescope to be proposed in about 2030 with a proposed cost of about $625 million and an expected launch date of 2043, but the actual cost should end up being something more like $27 billion and the real launch date will be in the 2070s and all of the supposedly great minds who dedicated their lives to the project will have ended up never producing anything of value during their long, well compensated careers in the service of "the people"

>>11307956
what the fuck are you gonna do once you get there? live in small, claustrophobic habs for your whole life, eating powdered food, unable to go outside without a million dollar suit which you can probably only use for work since you can't afford one yourself, no live internet, while your muscle and bones slowly waste away. what do you envision your day to day life looking like out there?

>>11308675
Better life than the puritans had

>>11308664
10 years ago, 1 million electric cars on the road was not "realistic". Now we're close to 1 million EV per year.

A lot can change in 10 years. Avg human estimation machines are immensely faulty and can't predict any rapid changes. We can't even predict what will happen 1 week from now. However those with greater intellect, those within the industry can predict fairly well within a year or so. DARPA thinktanks can predict decades in advance because they're leading the way. SpaceX gets the best engineers in the world, literally, the #1 engineers out of college want to work for SpaceX. #2 is Tesla. NASA is #5. If it works anything like Zipf's law, that means Elon has ~50% of the top engineers in the US working for his companies.

Too boring here, need dangerous horizon for meaning.

>>11308743
Yeah well what about working in an oil field or on a dangerous fishing boat or as a undersea welder? Lots of danger, lots of money to compensate for it, and maybe the freedom the money affords will help you fill in some of the gaps you're feeling (of course money can't solve most problems and certainly not malaise, but indirectly it can sometimes help)

Those aren't spaceflight-related careers, hard pass.
Stick me in a cramped tin can alone for 8 months, I am literally built for it and I think more than a few of us here probably are.

>>11308778
understandable, spaceflight appeals to me a lot too. If it were just getting in the tin can and going someplace no one has been before or where no one else is, that'd be great. But on thinking about it some more, you're not really playing Star Citizen in the sense of freedom to go, on your own, from place to place, to explore new worlds and systems, you are just plopped from one place to another and may be stuck there forever depending on the biological effects of low G long term. I feel that it is trading one prison here on earth for a smaller worse one elsewhere. There'll still be be people that you'll have to deal with. Some of them, statistically, won't like you. And they'll be virtually unavoidable due to the size of the colony at first.

>>11308810
>you are just plopped from one place to another
I like long road-trips. I'd be happy with a flyby of Venus or Mars like NASA wanted to do after Apollo, just being able to look down at another world for a little while would be worth shitting in a bag and eating freeze-dried food for several months.

>>11307995
It's taking them so bloody long. I'd love to know how far along they are. Have they built anything? Is it in test? If so what's the maximum speed they've achieved? Personally I'd be looking into building it at altitude given the shock the projectile is going to experience when it hits the atmosphere. I'd love this to work though because it might drastically lower the cost of launching inert payloads.

that's . . . stupid.

>>11309011
They don't have enough money to fly more than that, the fucking thing costs too much.

>>11307269
Only if they are providing a bigger expansion ratio, that is to say you scale up the nozzle in relation to the combustion chamber size. The highest expansion ratio nozzles have all been on quite small engines, typically the main engines of space probes, because they can have huge expansion ratios of 500 or more while only being a couple feet long.

>>11309011
By “the test” I assume you mean the static fire. The ‘Green Run’ is a lot more than just that, it’s a rigorous multi-month testing campaign and there’s much to do before the static fire can occur. The core-stage will also have to be refurbished after the static-fire..add this to the time required for assembly and GSE testing at KSC and the launch date easily slips into the first months of 2021.

https://www.nasaspaceflight.com/2020/01/sls-core-stage-stennis-green-run-campaign/

>>11309054
that's because it's paying for most of NASA's facilities

First there was "shuttle-C" in the `80s.
Then came the "national launch system " in the `90s.
In the `00s they called it "Jupiter" and "Ares".
In `09 there was the "Shuttle-Derived Heavy Lift Launch Vehicle"
Only two years later the shuttle was no more.
Last decade the "SLS" came around.
Now 36 years later, what have they archived?
One launch of a shuttle booster with an upper stage made from a mix of Apollo and STS parts they had laying around.

Call me a Musk-fanboy all you want, but at least the Falcon-9 and heavy are launching stuff into orbit after a fraction of development time and cost.

The radiation and high energy particles are pretty harmfull to microelectronics.
Even worse, the newer and smaller architectures are getting more and more vulnerable.

Problem is:
Limited scale production is prohibitly expensive and larger architectures are slower and less efficient.

Pretty much this. Rad """hard""" shit costs as much as a house for an obsolete part (and it still doesn't do as well as you might expect). Requirements these days are continually pushing for more memory, higher data rates, more complex software etc. Keeping in mind that power is also a big fucking deal (and once solar panels and batteries are specced, you're not getting any more buddy). Add in risk aversion to parts without flight heritage because the customer's got their one of a kind instrument flying on our satellite and it absolutely *has* to work, and it becomes a nightmare.

They can`t do that as they high energy particles fuck up the architecture of the processors themselfes, not just individual calculations.

Nah parallel processors are like three pipes running through a redneck shooting range.

It’s complicated: internal NASA realistic flight-readiness predictions currently suggest sometime in “late-spring 2021”. But all the lunar transfer windows from January through April 2021 are night windows, and NASA has a long-standing rule of only launching new vehicles for the first time in daylight conditions for visibility. Therefore, May or June 2021 are the most likely times when it’ll launch if current trends hold.
