Could you use air (or whatever atmosphere) as straight up reaction mass in a nuclear engine? Not like in pic related, but actually running air through as the fuel.

>>15951420
weve had landable missiles since the 1950's...

>>15951425
it staged for a reason fag. get out of here with that.

>>15951413
NASA being faking bastards does not mean the earth is flat or that space itself is a lie.
It only highlights that NASA are liars and their presented idea of spasce is a lie

Hey come on now dont be mean to him

>>15951425
You're not allowed to post twice
>>15951413
SHUT UP

>>15951425
Yes, but you still run into the problem of nuclear engines being very heavy as well as leaning towards the "higher efficiency but lower thrust" end of the spectrum. Even if the idea works out on paper, and they usually do, they never measure up well against more conventional options.

>>15951436
I wasn't going to post twice fuck you I'll change my mind

this idea is as close as I've found to your suggestion, but it uses the harvested oxygen as refuelling for a separate chemical rocket, and the nitrogen for nuclear electric thrust to offset drag instead of nuclear therm like I think you meant.

I remember a few years ago /sfg/ was discussing venus atmosphere harvesting and it boiled down to either floating platforms with cryogenic plants for air liquefaction or nuclear ramjet scoops in super low orbit

>>15951456
Not a high bar

>>15951479
>nuclear ramjet
I guess this is more what I was asking for.

>>15951463
What do they do

>>15951463
Three maximum, likely just two. VIPER has already been quietly delayed and there are no signs of hardware for the 2nd and 3rd IM landers.

Elon bad because Twitter met resistance from regulators/political ideology. Its such a shallow take that it really devalues Burger's reputation. He comes off as someone thats only able to see from the bubble he's living in and unable to see what the other side of the resistance is. Or atleast he doesn't elaborate on that

>>15951568
For me, it's now Stephen Clark, who is clearly being groomed to be his successor at Ars.

>>15951568
Isn't Berger Jewish? Not surprising to see he wouldn't like a guy brushing up with populist and nationalist political figures on twitter. I mean, I'm on Elon's side here but what did you expect?

>>15951568
I remember seeing something akin to that on twitter from him, but kind of vague
pretty dumb take though, very shortsighted and naive
you would think he is somebody that should understand how political spaceflight can be, 10-20 years ago it was basically completely under the whims of politics

A while ago I was running efficiency numbers for potential QI thrusters and I came up with a concept I call the Star Wars threshold, a point at which the overall electricity-to-thrust conversion enables flagrant scifi bullshit like fanless hovercars or direct SSTO with good payload fractions, and so on. As a rough order of magnitude estimate for working with current power supply technologies (diesel generators, batteries, fuel cells, solid core fission, etc.), that's on the order of 100mN/W, a figure which has been seen at least once on a tiny lab bench setup. The test thrusters on orbit now are about 1mN/W.

The future is closer than you think.

>>15951922
Umm how bout no?

>>15951425
so this is basically a nuclear ramjet? They already exist. US has tested them and Russia has flown them (they accidentally made a village uninhabitable)

>>15951791
Why are they so paranoid about this? What are they afraid the shitty space webcam could reveal?????

>>15951952
unmarked satellites, I suppose
seems so infinitesimally small a chance, and would require getting so close as to physically contact and blow both up, but rules on secrecy are very strictly adhered to no matter how absurd

---
https://arstechnica.com/space/2024/01/nasa-just-flew-by-the-solar-systems-most-volcanically-active-moon/
> On Saturday NASA's Juno spacecraft, which has been orbiting Jupiter for the better part of a decade, made its closest flyby of the innermost moon in the Jovian system.
> The spacecraft came to within 930 miles (1,500 km) of the surface of Io, a dense moon that is the fourth largest in the Solar System. Unlike a lot of moons around Jupiter and Saturn, which have surface ice or subsurface water, Io is a very dry world. It is also extremely geologically active. Io has more than 400 active volcanoes and is therefore an object of great interest to astronomers and planetary scientists.

Raymer is the worst textbook I have ever had the displeasure to read. None of his math is explained or derived, all of the statistical models are handed down from on high without explaining their bounds of applicability, and in the edition I had all of the SI unit values are incorrectly converted.

Gudmunnsson made a much, much better version of the same book called "general aviation aircraft design".

After that, they've got two Starlink launches coming up this weekend, and Axiom 3 and Cygnus NG-20 later this month. That'd mean they need six additional Starlink launches to keep pace with their twelve-per-month goal for 2024.

That said, they've got twelve possible Falcon mission in February before they start adding Starlink launches, so there's room to make up for a shortfall.

>>15953021
As said in yesterday's previous thread, he's either unable to understand the other side of the debate or the he does not wish to acknowledge the problem at hand. He and the interviewer claims that X met resistance from political ideology at the company and regulators, thats why X/Elon is bad. X is just as important as SpaceX/Tesla at this point in time. Without a free society, mars would be full of wokoe garbage wanting to tear it down. We cannot have a society like that. Humans cannot have a future like this.

>>15953028

>>15953036
simply not true, twitter is better than ever, transforming the business model to be something that is not purely under the whims of the advertisers is critical
the situation needs to be that advertisers need to go to X because it is a platform that has a lot of eyeballs and they can't afford not to, not that X needs to beg for advertisers approval for every fucking thing and anything that gets posted on the platform needs to be approved by advertisers
the later has shown itself to be a threat to an open and free society, and its simply makes the platform much more boring

They did successfully reconstruct a lot of the frames in the video, so the guys did manage something better than "tried." The reconstructed clip was used in the "how not to land an orbital class rocket" video.

So, what? An RS-25 with more than 475s of isp? I can't think of any reason why it'd be the weak link in the plan. Getting the hundreds of tons of hydrolox into orbit to feed that thirsty girl is always going to be the hard trick with that sort of mission architecture.

Io is actually one of the most interesting moons in the solar system. Its a pretty interesting target for colonization too for the outer solar system, since it has metals close to the surface. Unfortunately you'd have to set up a lot of radio infrastructure to drain the Jovian radiation belts, but by the time humans are colonizing the outer solar system that should be pretty trivial.

>>15953250
>trivial
I love /sfg/ handwaving

RS-25 is too overkill for deep space, with like two turbine stages and many moving parts. What's the simplest hydrogen engine you can get away with? Has anyone made a pressure-fed one?

>>15953255
It's more overkill because of it's thrust rather than its complexity. Simpler engine designs have lower isp and produce ships that need more structure and fuel for a given payload mass. That's why so many designers keep pushing for things like NTP despite all of the other engineering downsides.

>>15953142

By the time humans are colonizing the outer solar system, yeah, it'd be comparatively trivial.

It's not overkill for thrust though. You need to be measuring thrust in meganewtons to do anything interesting with interplanetary crew. That's why the Mars Reference Architecture has a few cuck sheds strapped to nuclear reactors and SpaceX is planning entire cities based on Starship fleets.

>“For Bob and I, that particular booster was always pretty special for a lot of reasons," said Hurley, a veteran Marine Corps fighter pilot who retired from NASA's astronaut corps in 2021. He now works at Northrop Grumman.
>“It’s kind of a bummer," Hurley told Ars.
>“SpaceX has got a business to run," he said. "I think, at this point, certainly Endeavour is going to fly more, but this booster isn’t, so hopefully they can find a spot to display it somewhere. Even part of it would look kind of cool somewhere. They could figure something out ... People, I think, can get a lot of inspiration from seeing stuff that’s actually flown in space, and being able to get right up close to it, I think, is a big deal to a lot of people.”

Given just how many players in oldspace needed a decade to accept that reuse even worked with the Falcon 9, and given just how many newspace entrants were inspired to repeat SpaceX's early attempts while not paying any attention to the lesions that SpaceX learned from them, I'm not sure how many people in the industry actually understand the industry.

why is China making both the long march 9 and 10 if they accomplish the same mission?

>>15953535
Corruption

>>15953397
Any updates on skitzodrive?

>>15953535
First, they're not doing the same mission.

The LM-10 is a rocket that China can build with the tech they have right now that's big enough to handle a lunar mission in just two launches. Later on it can be cut down to just the core in the LM-10A and have reuse tech added on from one the independent groups to produce another Falcon 9 equivalent.

The LM-9 is in a bigger weight class that's intended to compete with Starship. It's supposed to be used to support a lunar outpost after the LM-10 missions have run the flags-and-footprints routine, or maybe for geostationary solar power if Beijing decides their still interested in that. The LM-9 is going to be using next-generation engines (which is why it's a mid-2030s rocket instead of a late 2020s one) as well as reuse tech right from the start.

They also might have been pushed originally by different chief designers. China is not immune to Korolev vs Chelomei drama.

>>15953526
Most of "the industry" had never started from zero themselves, they were forked off of ICBM programs started during the Cold War which in turn had roots in Peenemunde. SpaceX and Rocket Lab are the only two consistently profitable companies to pull that off.

>>15953546
Still waiting on authorization to turn it on.

>>15953554
I agree with the idea of your post, but SpaceX is most definitely not consistently profitable and neither is Rocket Lab. You could've chosen so many other attributes that'd fit other than this one.

>>15953555
If they turned it on and it worked, do you think they'd tell us, or would it get swallowed by some NRO/USSF black budget program? Is there anyone outside of this underwater Micronesian basket weaving forum following it?

>>15953561
I was trying to find some way to differentiate from the Chinese companies that get infinite 0% loans as long as they keep hiring.

>>15953564
There were a few schizos doing QI garage tests back in 2020-2021 but due to various normienet ban sprees /sfg/ is the only place that consistently knows quantized inertia is even being tested still other than direct replies to McCulloch and Mansell (IVO CEO) on Shitter. Mansell would absolutely announce that it worked because his goal is a jump to TRL 9, a mass produced product people can buy. At this point I think the black projects have their own test hardware - I'm legitimately half convinced the X-37B OTV-7 is using a Horizon Drive to perform "impossible" maneuvers as described

In addition, they will also conduct a Pad Abort Test (PAT-02) and an Integrated Air Drop Test (IADT) this year.
I'm still a little surprised that they plan to crank out this many launches for a single program before the end of the year. If they can manage all of that a crewed launch in 2025 doesn't seem unreasonable.

>Nobody's seriously entertaining the idea of Starships that fly once a day.
Not yet
SpaceX is going to demonstrate it at some point. It's one of the reasons the tank farm has been expanded. While they clearly didn't need the expansion for IFT-1/2 it is needed if you expect launches in quick succession

>>15954152
Shut up chud

>>15954157
The original idea for the Shuttle program was to have a fleet of four orbiters each launching 24 times per year, for a total of about 96 missions, for about $2000kg. Falcon 9 launched 96 missions last year, most of which were carrying a payload equal to a max-capacity Shuttle flight, for about $1500/kg. No one has ever really bothered to think about what a fully functional Starship program could look like beyond "a lot of big, cheap launches happen off camera" in something like The High Frontier.

>>15954187
Shuttle sucked end of story

>>15954187
Full Starlink v2 upgrade is the obvious one. Beyond that it starts to outrun the market. Crew rating and then a Shuttle style crew+clamshell+arm construction variant to build spinhabs or space solar power is my best guess for a capacity soak. Then Mars.
