On that note, what's the smallest rocket you could get into leo with like 5-10kg of payload?

I've always wanted to get more out of the 0.625m parts in ksp but there's only so much you can do before strapping boosters to the sides and all. I mean I don't expect to get Kerbals to the Mun, but a small streamlined cockpit would be nice for the early game and miniaturized rovers, I mean throwing really tiny stuff at Mun and Minmus should be in the cards. Overall, any tricks on really light weight space faring? I reluctantly installed TweakScale...

Not how it works. Rocketlab for instance is more expensive for a given payload than a Starlink rideshare, but stays competitive due to more flexibility.

It was a dodgy transition, but I didn't bring it up again. Also, early rockets were small, that indeed made it cheaper to test them and lower tech, so the transition wasn't that dodgy after all.

>what's the smallest rocket you could get into leo with like 5-10kg of payload?
The record for smallest orbital rocket has been held twice by Japan, first for the Lambda-4 (16.5m), and they beat their own record just last year with the SS-520 at 9.54m.

>>12096392
It's a decades old idea. He's using new physics (non-Gaussian beaming) with cheap microwave/RF emitters combined with using the beam to drive a jet engine for suborbital travel.

>>12096579
Why did they choose that retarded battery layout. Apparently the weight penalty offsets the savings of not having the motor spin up from lost exhaust

>>12096606
Idk about that but it is much easier to make and maintain the engine.

>>12096606
Just a guess, but it might not be about rocket efficiency. If you can get the same specs from a complex engine vs. a battery engine, they might have gone with batteries for simplicity. It’s probably easier to build and / or maintain

>>12096606
It significantly simplifies the engine when you don't need a gas generator to spin it up. Fingers crossed somebody starts mass manufacturing the newer solid electrolyte cells soon, or that Canadian firm finally commercialize the Braga/Goodenough glass battery.
At that point battery-powered turbomachinery might actually outstrip conventional gas generators, including in larger rocket engines.

>>12096626
I just want a 10x energy density boost for EVs.
>ebikes capable of going 100mi at 50mph
>Teslas with a 20 hour highway driving range

>>12096626
You'd need both high energy density and high power density, and they don't necessarily come hand in hand. Hence afaik Rocketlab uses lipo batteries that have shit energy density but high power density, new tech that focuses on increasing energy density is great for most applications but useless for that.

I’m a noob when it comes to battery tech. What separates a “good” battery like a tesla from a shittier one like what I would find in a prius? What advanced did Elon make that made tesla so damn good? What could be improved? Are we anywhere close to electric planes and stuff

>>12096635
I mean even if the best you could get is 5x capacity and charge rate (as is purported to be the improvement of the Braga/Goodenough battery) you're looking at 2000 miles of range for an EV with a full charge time of 9 minutes.
>>12096644
I might be mistaken, but both solid and glass electrolyte batteries, at least in early lab condition tests demonstrated both superior charge/discharge capabilities, greater endurance over many cycles, and a greater range of temperature tolerance compared to their liquid electrolyte counterparts. As far as I can see they'd be superior in literally every measurable trait compared to current cells, including both ease of manufacture and cost.

>>12096655
If all of that shit were true there'd be nothing keeping them in the lab because they've solved all of the technical hurdles in battery production. Never believe anything you read in battery production that doesn't have an independently verified product associated with it.

>>12096654
Energy density, weight, duty cycle, cost, battery pack size. By all these metric, Tesla is leading the way with 3-5 year advantage ahead of anyone else.

You could argue "but researchers have found better batteries blah blah blah" USELESS!!!!!!!!!!! USELESS!!!! Papers don't power anything. Manufactured batteries do. All the "next gen" battery papers have a big manufacturing/cost problem.

>>12096606
Didn't they recently update their specs thanks to the improved batteries? Afaik the payload was increased and reusability should be more viable because of it.

>>12096654
A good battery depends a bit on what you want, for turbomachine batteries (and the kind you'd use in battery aircraft) you need to put out a lot of power quickly, for EV car batteries you need moderately high power output but also significant endurance, and for stuff like phone and computer batteries you need relatively low power output but preferably long endurance to maximize up time.
Of course, the "ideal" battery will have both very high power density and very high energy density per mass, IE smaller batteries with larger capacities and higher power outputs. Solid electrolyte and glass electrolyte batteries are moving in that direction, both have higher charge/discharge rates than liquid electrolyte cells, both have higher capacities, and both have longer overall lifespans. They're also more durable inherently, less prone to or completely immune to certain failure states, and cheaper to manufacture at the large scale.

The batteries in most cars are old lead/acid batteries, primarily used because they are cheap and easy to mass manufacture, their energy density and power density is pretty shit, their discharge efficiency can be pretty bad, and their lifespan can be as low as 300 full cycles. Tesla batteries by comparison have higher specific energy, higher energy density, higher power density, roughly comparable discharge efficiency, and a lifespan of up to 2000 cycles.
>>12096666
There are several companies actively working on different types of solid-electrolyte batteries right now and a smaller company in Canada signed a deal with Braga and Goodenough to commercialize their cell sometime in I believe 2021, we might see an operational unit as soon as next year. I'd imagine the primary hurdle has been developing the mass production process, since it seems like a lot of better battery chemistry is already understood. Production lines are expensive and time consuming to set up.

>>12096258
Lol you even took the big ass photoshoped version some anon made here, cheers mate. Now all we need is a video with wide rockets launching as "song of denise" plays on the background.

>>12096676
>There are several companies actively working on different types of solid-electrolyte batteries right now
That's been the case for close to a decade now. Claiming to have a magical battery that has all of these performance benefits but never producing even a demonstrator prototype and falling into obscurity is routine, and if all of those things were true there would be no barrier to doing that much.

>>12096258
First one of these I actually laughed at.

>>12096703
I can't say for all of the companies off the top of my head, but I'm fairly certain the Canadian company working on the glass battery has only been trying to commercialize it for the past three (soon four) years.

Very informative and very interesting. It’s seems Elon’s biggest strength is his general science / business knowledge and the ability to enter any market with the mindset of “if I gather hardworking young people we can capitalize on the laziness of old people”. He turns everything into an engineering problem and has his team work on stuff considered “impossible” just by pushing it as an engineering problem to his workers

So there was a proposal to reused Saturn V first stages. The stage would have parachutes. Then a giant helicopter would hook the chutes in mid air. Reel up the chutes and fly with the rocket snug against the underbelly.

Could a falcon 1 with a newer Merlin engine compete with rocket lab

>>12096974
Small rockets are obsolete with ride share. A F9 can put multiple payloads into different orbits.

>>12096980
This. Bigger rockets are more efficient per kg, especially with reuse. Efficient rideshare buses is the name of the game for smallsat launchers now. Imagine a 50 ton rideshare bus with 100 tons of smallsats, all on one reusable Starship for $2M. That's less than $1000 for a 100kg smallsat even with enormous markup for a custom orbit... or you could have the same rideshare bus with ten tons of smallsats put into orbit around the moon.

I think Wal-Mart is introducing these as mobility scooters now.

>>12097045
that's not SLS, that's Jupiter

>>12096997
The golden age of space engineering companies is upon us. Rideshares are much cheaper than a small dedicated rocket, but only go to so many orbits. Selling "last-mile" small orbit changing solutions will be a huge business. Just make a small tug, it can run on whatever you want (kerolox, hydrolox, solar thermal hydrogen, ion drive...) and sell it to customers who need a different orbit. With the mass costs being as low as they are getting already with F9 rideshare, and even lower for Starship rideshare, Rocket lab and other small launchers are in for a challenge.
The big leg up Rocketlab has is that they are not only a launch provider, they really hold the customers hand all the way as an all inclusive. Photon fits this model perfectly. They will need to figure out reuse soon though to be price competetive.

>>12096654
Both use Lithium Ion. Tesla just tweaks the chemistry a bit more. But their real lead is in the cooling systems and the software for the battery. They really optimize the power usage and charging.
That being said the Hyundai Ioniq is actually king of efficiency right now. At least it was last time I checked. Tesla has improved a bit again since then.

>>12097049
I think it will be a good business choice considering the weight of the average american

>>12097056
IIRC they're doing parachute reuse on flight 17, so two after next.

On the space tug front I think the next big thing is those same high density batteries/supercapacitors. If you can do high thrust+Isp burns on stored power (say, 1MW of ion thrusters) and use solar to charge during coast phases, you can avoid the need for nukes until you head out past Mars, even for small manned missions.

I know rocketlab have said they want to stick with smaller rockets, but ill they move up in size class at least a little bit? a thousand kilogram launcher seems like a great niche to eventually move to, esp with reuse.

Also William Shatner was there for some inexplicable reason.

That's the basics of it. It allows more companies to comfortably bid on projects that previously they didn't have the money to do. An issue with this method is that unless you can establish strict guidelines and enforce them, those companies are just gonna pretend to have issues with development in order to milk money from you.

A contract in which the company is paid for all expenses incurred *plus* a guarnateed sum on top of that to ensure profit. It was introduced in the US just before the first World War and expanded greatly in use during the Second World War to boost the productivity of otherwise small companies by allowing them to bill the government for RnD and still be guaranteed to come out ahead no matter how much they needed to spend.
It was always essentially a form of corporate wellfare, and should be disallowed entirely except in times of war or other national emergency.
A fixed price contract by comparison is when companies pitch what they believe is a reasonable cost for their work to the government, and the government agrees to pay them that much when the work is done.

Under fixed price:
>Company A offers to build a rocket engine to NASA specifications, they assume RnD will cost a billion dollars.
>Unexpected shenanigans occur, space is hard, it ain't that easy in rocketry, etc.
>Company ends up spending 1.2 billion.
>NASA only pays out the original 1Bn, company eats 200 million in losses.

Under Cost+:
>Company B(oing!) offers to build a launch vehicle to NASA specifications, they project it will cost around 7 billion dollars.
>Company drags it's feet and claims that there are shenanigans, space is hard, it ain't that easy in rocketry, etc.
>Cost overruns to 9 billion+ and the project is dragging an increasing amount of time beyond the original schedule.

You know having a manned first stage doesn't seem too crazy.

>>12098090
Lmao imagine making it through the astronaut process only to get stuck as the pilot for the shuttle’s shuttle’s shuttle. No spaceflight for you nigel!

>>12098094
You wouldn't have to be a trained astronaut, you'd just be a pilot. Should have stayed in space school pal.

>>12098090
It's the only way to get full reuse without modern (2010s or later) computers. Now that F9 has done automated RTLS it's not so necessary.

>>12098100
Yeah basically with today’s technology you can remotely land your TSTO rockets. And also propulsively land, so you can ditch the dead weight of wings. Basically lockheed proposed the best option (for the 70s) and elon is building the best rocket available (for the current era).

Imagine if lockheed had an unlimited budget, they would probably build something similar to starship

>>12098088
Well that's fucking disgusting,and yet another reason private spaceflight is much better than this oldspace shit.

November 2021. Again, if it doesn't get delayed again.
>That’s not too far behind schedule
It is three years behind (five if you count Constellation). That is heavily delayed considering that most of the major components have already been made, and the new components are relatively much simpler and definitely don't require nearly a decade of development. Adding on top of that, former NASA administrator Charles Bolden is on record stating that SLS has been ready for it's final test run since 2014, and now it has been sitting on that test stand for nearly a year with no progress.

Space flight is not software development, rapid iterarion does not work. You have to play safe and test things, safety is paramount.
Musk is playing with fire and he will get burned. And when he does, he will not only kill hundreds of people and be arrested but will set space exploration back a decade.

>>12098337
SpaceX keeps putting frogs and four leaf clovers on their mission patches. Elon is our guy.

>>12098547
Rapid iteration worked well enough when the US went to the moon.

>>12098547
That already happend it was called the challenger then it happened again and again, and so far no one wants NASA to do anything, that's how we got Musk.

I know this is a trollpost but some braindead nigger believes it. This shit makes no sense. This is how you end up with the SLS flying manned with all systems untested because your culture of total safety eradicated the budget for proper testing of your overpriced equipment.

>>12098738
Well you could have a subpar safety system and a subpar testing.

They went for safety first.

Today in history:
>1966 - The landmark American science fiction television series Star Trek premieres with its first-aired episode, "The Man Trap".
>2004 - NASA's unmanned spacecraft Genesis crash-lands when its parachute fails to open.

>>12099896
The name is slightly clever.

>In October 2001, Musk traveled to Moscow with Jim Cantrell (an aerospace supplies fixer), and Adeo Ressi (his best friend from college), to buy refurbished Dnepr Intercontinental ballistic missiles (ICBMs) that could send the envisioned payloads into space. The group met with companies such as NPO Lavochkin and Kosmotras; however, according to Cantrell, Musk was seen as a novice and was consequently spat on by one of the Russian chief designers.
>The group returned to the United States empty-handed. In February 2002, the group returned to Russia to look for three ICBMs, bringing along Mike Griffin. Griffin had worked for the CIA's venture capital arm, In-Q-Tel, as well as NASA's Jet Propulsion Laboratory, and was just leaving Orbital Sciences, a maker of satellites and spacecraft. The group had another meeting with Kosmotras and were offered one rocket for US$8 million. Musk considered the price too high, and stormed out of the meeting. On the flight back from Moscow, Musk realized that he could start a company that could build the affordable rockets he needed.
>tfw the only reason spacex exists is because russians are cunts

>>12099896
Why a feather?

>>12099908
Aside from SpaceX as we know it not existing, what would've happened if these plans came to fruition?

>>12099916
Musk may have been content with using cheap russian missiles and focused on small payload work. SpaceX might exist as a minor but reliable smallsat launcher. BO would probably be a much more widely followed and popular aerospace company.

>>12099916
From what i remember they would also reverse engineer the ICBMs to be able to produce more of them, so SpaceX rockets would be very derivative of russian missile technology, so they would probably resemble and function a lot like russian rockets, there would probably be more of a skepticism and doubt towards SpaceX from americans due to the "russian missile technology" part

Yeah, that's not a problem either. You just tweak the control parameters to work with the larger vehicle.

>>12099945
I wonder if Spacex would have gone hard on hypergolics if they'd gotten Dnepr.....that would have probably made them a lot more controversial given how nasty that shit is.

https://spacenews.com/gerstenmaier-warns-against-ending-space-station-program-prematurely/

2025 does seem early-I think keeping the lights on till 2028 makes sense. We could even see the station massively expanded via Starships and the old sections enshrined as a sort of museum.

>>12099988
>https://spacenews.com/gerstenmaier-warns-against-ending-space-station-program-prematurely/
I think it'd make much more sense to create a completely new station with starship starting in 2025 imo, with the ISS fully retiring by 2028.

>>12099361
I used to have an unlisted youtube video in my favorites of a test of a hydrogen-oxygen pressure fed gas-gas RCS thruster, which had two nozzles and a huge gimbal range rather than four fixed nozzles in a cross, but it seems to be taken down. I think it was in development for ACES at one point, but that whole upper stage concept seems to be stuck in stasis now.

>>12100004
>>12099988
I don’t see a problem with keeping the ISS alive indefinitely if it’s being funded by private entities. Also worst comes to worst we should have Starship take some modules home.

Just like the shuttle, I know the ISS has issues, but it is still a marvel of engineering.

>>12100090
>Also worst comes to worst we should have Starship take some modules home.

They should disassemble it and bring the whole thing home via Starship so it can be put on display at the Smithsonian.

>>12099916
As I recall, the goal was to put a tiny greenhouse on Mars and send pictures/video back as a way to inspire the public and reinvigorate interest in the space sector.
I think Spacex would have gone on to develop in-house rockets in fairly short order. Musk would never be happy long-term playing the smallsat game with repurposed russian missiles. It's just how his brain works.
