So does Mars actually have life or nah?

>>14747030
It will have life in future

I'm gonna ask my question here as well since my thread got badly derailed.
There will only be two unmanned Artemis missions and then the third one will be both the first crewed flight and the first to land on the Moon.
If you compare it to all of the missions NASA did before Apollo 11 it almost seems rushed, or am I just paranoid?

So no one is gonna post how this was flight hardware and all the posers on reddit/twitter/L2 AND sfg were wrong? typical

>>14747030
The samples should be returning any day now

>>14747036
Why arent robots and rovers and AI robotics systems not good enough to go there first and set a nice environment for humans to arrive to?

Or I geuss robots and AI alone cannot be trusted to perfectly put together some base or solar array thing.

>>14747036
we've already had an apollo 4/6 equivalent mission for orion and we're going to have an unmanned HLS demo landing before artemis 3 which is going to be a more rigorous test of the system than apollo 9/10 were for the LM. we aren't having an apollo 7 equivalent mission where a manned orion is tested in LEO before sending it to lunar orbit but we also don't have a rocket for sending orion to LEO either.

>>14747036
it's only 1 unmanned mission, Artemis 2 will be a manned flyby.

>>14747036
Today's computer modelling is massively better and we do have half a century of experience in spaceflight we did not have back then. Obviously I'm not saying we don't need tests but there's no reason that as many should be needed.
>>14747044
Because it is, as ever, a propaganda mission at its core.

>>14747036
They're compressing a hell of a lot of tests into Artemis I

The abort system's been verified, orbit characteristics have been verified, the re-entry and splashdown system has been verified, now all that's left is the big stuff: the euro service module needs to be tested rigorously because it's the other half of the program and it hasn't been flown in space yet

>>14747059
Highly bodily and mentally skilled and able Robot AI are going to be such a massive part of building and actioning and constructing and mining and carrying and unloading and scouting and manufacturing.

Imagine mass producing some body able robots to weld a large structure in orbit.

>>14747038
>>14747030
Did any of the mars rovers that picked up samples microscope andor chemically analyze the samples?

>>14747073
wouldn't it be incredible if esa managed to fuck up something as simple as an aj-10

>>14747086
It would reflect really badly on them, because the whole reason they're doing this is to pay for their spot on the ISS

>>14747076
>Imagine mass producing some body able robots to weld a large structure in orbit.

On ISS? This doesn't make much sense.

>>14747097
lmao you are not the first to observe that it makes no sense

>>14747097
Space agencies don't exchange funds, so they trade services in-kind instead

When does an orbiting station, for science or tourism, start getting too big to easily keep in steady orbit for a long period of time, possibly even risking a sudden quick descent towards earth.

For example, some concept drawings and videos posted in the thread of large structures with seemingly no capability of thrusting or gaining or losing in orbit

>>14747108

You tried I guess.

>>14747195
We don't know what its specs are

>>14747197
We know what the contract requirements were.

Can they fit in the 20 engine B7 SF with the Starship 6 engine SF tomorrow? Overpressure notice

Wait are you fucking serious. Viasat still has subsidies but starlink doesn't?

>orbital prediction error

>>14747037
anon, the fact that it's a couple of meters off the ground does not mean it's flight hardware.

>>14747222
Checked, but people need to stop sucking his dick

>>14747231
Is it technically still an orbital-capable spacecraft if I make my rocket's launch tower 100km high?

>>14747220
they are not firing 20 engines on the booster tomorrow bro. maybe they do 3. maybe they then do 5 the same day.
not 20, they're not that launch feverish

>>14747195
Hey retard, the complaint in the last thread was that NERVA was too heavy and lighter NTP engines are possible. The NTR I posted uses three modern 4 ton engines. If you want to deduct 4.5 tons from the 400+ ton rocket to account for even lighter engines that weren't part of the design, you can but it wouldn't change shit and you're only upset about this because you are severely autistic.

>>14747205
That's NASA's (run by DOE) RFP. DRACO, the one General Atomics designed, is something else and will likely remain classified, although I notice DARPA's phase 2 and 3 RFP mentions NASA is more than happy to collaborate on NTP designs.

>>14747231
>>14747037

what proof does ANYONE have that this is a fake and not a full up prototype? because you dont put a trillion rivets on a throwaway rocket

What would be the best way to mine an asteroid once you've landed on it? Drilling the entire way for every scrap would take forever and Newton's third law would make it a bitch to use multiple rock breaking machines. Plus the omnipresent threat of the asteroid coming undone and wrecking everything. Do we have any solid techniques to mine an asteroid effectively?

>>14747264
Do you actually think the first tank ever of a new rocket is going to fly? It'll be cryo-tested, pressure tested, pad fitment tested, dynamic load tested but I seriously doubt it's be flight tested.

>>14747266
Pretty much no asteroid is solid
They are all rubble piles
Even psyche

>>14747266
You use spectrometry to pick one and then bag it and throw it into the moon. If you are fucking around with asteroids before you are mining the moon you are doing it wrong.

>>14747282

>>14747266
The aussies have diggers with jacks that extend into the ceiling to hold it stable.

>>14747195
Let's look at that proposal, as surely it must be better than (>>14747245) and both must be better than Starship.
>8 SLS launches to NRHO and LDHEO for crew vehicle
>5 SLS launches for cargo vehicle
>SLS Block 2 is required
lol, lmao, possibly rofl

>>14747252
NASA isn't going to pay for a separate NTP development when they can just use the one General Atomics designed for DRACO.

>>14747340
those are 3d proonted tanks aren't they? i think i'm having a seizure.

>>14747340
I used to look twice at all the double-thick parts I saw going onto spacecraft until I realized this was all because vibration testing will break your shit real quick if it isn't that big

>>14747245
What I enjoyed most about your choosing of a decade old NTP conjunction mission was that you bragged about Starship having enough delta V to meet the same requirements when the point of nuclear propulsion is having enough delta V for an opposition mission.

>>14747356
Vibrations are a meme

>13 SLS launches
Sweet it will only take 15-30 years to assemble it then

>>14747402
but i am

>>14747403
None of the proposals in that paper require 13 SLS launches, though there are some that require nearly that many. The one that uses Starships is the only one without an absurd number in order to assemble the transfer vehicle.

>>14747417
Anything that requires more than one SLS launch can't work

>>14747425
I doubt any actual mission will use more than one SLS and it will be used to launch the reactor in a cold state.

>>14747227
the atmosphere is hard
also the earth's gravity is lumpy
also measuring distance and speed is hard

>>14747264
you don't put rivets on a real rocket, rivets and other through-fasteners are only used to connect dissimilar metals together (somebody has stapled a rocket-shaped skin onto a frame)

>>14747432
We don't even know what gravity is

>>14747340
hmmmmmmmmmmmm
banan

>>14747382
Kek, I knew you'd move the goal posts back to opposition transfers, chemical propulsion has enough delta-v for both as per the presentation you posted last time which ironically sunk your argument to the point you stopped responding, presumably out of embarrassment.
>decade old NTP conjunction mission
Once again you've defeated yourself by posting (>>14747195) as an alternative which in all forms is objectively terrible. You can double down by pretending the DRACO NTP engines would completely change the architecture but they wouldn't. You are mentally ill, seek help or kill yourself.
>>14747417
>None of the proposals in that paper require 13 SLS launches
That's a flat-out lie. In some proposals the crew + cargo SLS launches would exceed 13.
>The one that uses Starships
You mean the one that uses 5 SLS, 2 New Glenn and 4 Starship launches.

>>14747435
true but our heuristics for measuring its effects are not the source of the error

>>14747403
Reminder that NASA intends to mass produce the SLS
>https://www.nasa.gov/press-release/nasa-prepares-for-space-launch-system-rocket-services-contract/

>>14747444
Mass produce means once a year(long term goal)

>>14747438
Anon we have always been talking about opposition missions, if anyone moved goalposts it was you.

>>14747264
Well, you could start with the obvious, like how it's full of structural beams and absolutely zero fuel tankage, plumbing, etc. Or that it's riveted together in a way which would survive neither flight stress nor pressurization with cryogenic liquids.
It's a hollow, functionless shell for display purposes only.

>>14747444
>We're going to reuse 50 year old technology on a cost+ basis with minimum advancements in manufacturing, fabrication, functionality of the vehicle, mission scope, etc for 100 more years.
You know what, I believe it, NASA really could be that retarded.

>>14747446
>we
No, the person I was talking to had an idea of a reusable nuclear thermal tug that would do conjunction TMIs before detaching and returning to Earth for reuse. A chemical stage would then do direct entry before refilling on Mars and returning the next window. You added yourself conversation by crying foul over the design I posted just show the limited payload and delta-v of a realistic NTR despite high complexity and cost.

>>14747328
Why don't they just plan to use Starship?

Why don't people get that colonizing space and other planets is essential to protecting the Earth?

Look at Europe before and after the New World. They were at Peak Wood, famines, etc. The new world off loaded people from Europe. Brought new resources to Europe.

If we stay on earth. All the economizing and sustainability* in the world is still going to end badly for humans and wildlife.

>>14747540
And all that with just 6W!

>>14747515
There's only so much energy you can get out of an exothermic chemical reaction, electric propulsion is able to put more energy into accelerating propellant regardless of the molecular weight, at the expense of thrust. I don't know anything about that thruster but Momentus has demonstrated Isp well beyond hydrolox using water plasma propulsion.

>he thinks higher Isp than hydrologgs is impressive
Isp is like miles per gallon, it only shows how efficient you can use the fuel. It's great if you're already in flat space and can slowly use your fuel, but it's fucking useless without enough throost to get out of a gravity well.

> being a filthy well dweller in the first place
Any body you can't tunnel all the way to the centre of is too big and should be broken into pieces that you can tunnel all the way to the centre of. Even Ceres is iffy

>>14748157
The body is weakened by 0g,
the soul is weakened by 1g.

>>14748161
Therefore spinhabs - going from 1g to 0g is just an elevator ride away

>>14748177
Low gravity swimming pools sound like they could have unique dangers. If you do a cannonball into the pool, the expelled water is going to take longer to hit the surface. On the other hand, your splash will be smaller since you'll have less velocity but in a pool full of activity, how long would it take to end up with the air in the room full of droplets everywhere? Probably not much of a problem at 0.9g but at 0.1g? With droplets all over the place, would it be worse than 99% humidity in a place like Louisiana?
Even with surface tension and general adhesion, could you end up swimming and hitting a low density water pocket, which would be difficult to swim through because you are pushing against less water?

>As Musk sets our collective sights on Mars, a town in south Texas and nearby wildlife reserve are being sacrificed on the altar of his personal ambition

Sacrifice the BEETLES

>>14748229
I think the important thing is to have enough gravity to keep the water from sticking to you due to surface tension until it suffocates you or something. Which probably doesn't need much inertial gravity to overcome.

>>14748229
>>14748255
I could see surface tension being dangerous in micro gravity, outside of that I think it would just be a pain in the ass.

>hit with the same force as a 10m board @ 1g

While not dangerous you are going to need to round up the water with a pole or something before you open the door to the pool room.

Its because of Biden/Democrats want to punish Elon Musk and his companies.

>Republican Commissioner Brendan Carr issued his own statement after the announcement — saying he did not know about the FCC’s decision until the press release, disagreeing with the decision.
>“We should be making it easier for unserved communities to get service, not rejecting a proven satellite technology that is delivering robust, high-speed service today,” Carr wrote. “To be clear, this is a decision that tells families in states across the country that they should just keep waiting on the wrong side of the digital divide even though we have the technology to improve their lives now.”

Eh, compared to like SLS, the fact that SS already has generated more than 10 prototypes, 7 of which have functioned, Elon's certainly not screwing around.

the first time SLS fired it was 4 engines for a few minutes. Bet their FAA paperwork was done years ago!

>The individual engine component tests were followed by the first test of a complete engine (0002) on March 16, 1977. NASA specified that, prior to the Shuttle's first flight, the engines must have undergone at least 65,000 seconds of testing, a milestone that was reached on March 23, 1980, with the engine having undergone 110,253 seconds of testing by the time of STS-1 both on test stands at Stennis Space Center and installed on the Main Propulsion Test Article (MPTA). The first set of engines (2005, 2006 and 2007) was delivered to Kennedy Space Center in 1979 and installed on Columbia, before being removed in 1980 for further testing and reinstalled on the orbiter. The engines, which were of the first manned orbital flight (FMOF) configuration and certified for operation at 100% rated power level (RPL), were operated in a twenty-second flight readiness firing on February 20, 1981, and, after inspection, declared ready for flight

>>14749489
In theory BO is coming close, but they been like those for a few years and not much has changed since then.
Next you have Rocket Lab, that is making basically a better version of Falcon 9 that also can compete with Starship. After all, the majority of payloads do not require such powerful rockets.
Relativity is behind Rocket Lab, but their future rocket is basically a mini Starship.
And, that's it? There are also Chinese and French working on their reusable rockets, but God knows when those are actually going to launch.

>>14749494

why isn't BO using a pressure fed engine for NS, it seems like the logical choice for a rocket with low performance requirements

You say that as if it's a big deal. Nasa did autogenous pressurization in the 60s. and hate to break it to you but 8min 4-engine sls static fire is a lot more impressive than a 20s single engine fart

>>14749736
It's weird that they're still trying to push this line. SLS has already been rendered almost useless by Falcon Heavy, and it will continue to get worse for them as more commercial HLV become operational. The only thing keeping it alive, aside from grift and corruption, is the taxi service to Gateway and to be fair, that job could be done by commercial rockets, for a much lower price, if propellant depots became available.

your weekly musk/spacex hit piece anons, have a good laugh
https://time.com/6203815/elon-musk-flaws-billionaire-visions/
>Elon Musk Is Convinced He's the Future. We Need to Look Beyond Him
>Musk admitted to his biographer Ashlee Vance that Hyperloop was all about trying to get legislators to cancel plans for high-speed rail in California—even though he had no plans to build it.
>As Musk sets our collective sights on Mars, a town in south Texas and nearby wildlife reserve are being sacrificed on the altar of his personal ambition. SpaceX recently fired employees who wrote an open letter asking it to distance itself from its increasingly controversial CEO, while astronomers and Indigenous groups have expressed concern about what Starlink is doing to the night sky.
>In crafting his future visions, Musk draws on the libertarian tendencies of Robert Heinlein and a technocratic longtermism inspired by Isaac Asimov’s Foundation series, not to mention the dreams of Nazi-turned-NASA rocket engineer Wernher von Braun. Future visions cribbed from the pages of science fiction—often of the dystopian variety—and reshaped to fit the desires of the richest man in the world don’t serve the broader public.
>Kim Stanley Robinson, whose Mars trilogy helped inspire some of the recent interest in colonizing the red planet, has called Musk’s plan “the 1920s science-fiction cliché of the boy who builds a rocket to the moon in his backyard” and one that’s dangerously distracting us from the real problems we face here on Earth.
>What we really need right now is not more cars, colonization dreams, and technokings, but a collective project to improve the lives of billions of people around the world while taking on the immediate challenges we face regardless of whether it generates corporate profits. That’s something Elon Musk can never deliver.

Because 20 is a lot of engines? Its not like Falcon Heavy uses 27 engines...

who cares about spaceflight? your governments have tech that can cover vast distance probably instantly
why debate the progress of a slow process doomed to fail when the result already exists? there is no need for further study when you have results it's just wasting time pointlessly

>>14749814
it was venus, bro

>>14749773
because fuck california

>>14749814
well you see if we pee the poo we can actually get the poo instantly into pee (full flow stage pee), thus making the isp near infinite without autogenous poo pressurisation limiting our mass fraction
This is simply why we do science

Ok so i heard Blue Jarvis is hiring? are they finished building it? lets light this candle!

>>14749280
Based on past tweets by Elon, I think they're moving 1 > 3 > 6 until they can fully test the entire inner ring; which is what they need for upper atmosphere slow down burn and then need the entire central ring during landing until they shut down to 1-3 for the hover and tower capture.

>>14749776
They're trying to associate Musk with Nazis. Because Nazis are bad.

>>14749840
Not sure where people get this expectation that superheavy will hover. It CAN hover but it WONT. Hovering is an incredible waste of fuel and by extension mass. See Blue Pee and their fucky hover landings, they're just embarrassing. Superheavy will come in much hotter than anyone here realizes

>>14749849
this thing is disgusting

>>14749842
I just vant to build rokets

>>14749807
Falcon heavy is 3 cores with 3 separate tanks, not 27 engines sipping from the same tank.

>>14749773
Because he was a californian resident at the time, and the highspeed rail project was being derailed by cost overruns, that is now stated to cost well over $120B by the time it maybe finished in 2030s/2040s. Becoming the slowest "highspeed" rail as well the most expensive in the world. All the while, the price estimate for customers using the rail has increased dramatically from $50 to $100, and by the time its done, it will likely be $150-200+, unless California pays for more subsidies and hides the real cost. For a one way trip.

Could Orion be compatable with most medium/heavy lift rockets?

It doesnt look too different in size and shape to Dragon or Starliner.

Could it fit on Terran R/Falcon 9/New Glenn/Vulcan etc? It could be another reason/excuse to have spent so much money on the program to have more uses for Orion

At that point no rocket in the world aside from SLS will be able to lift it

The concept looks pretty sound to me, toyed with a couple similar ideas in my brain before. Funding and bringing it to production along with whatever government cocksuckery you need to do so they let you build a manned giant fuckoff space station is a whole other story though.

here is a dumb idea
could astra sell/give the knowledge of rocket3 to some college or hobby group?

>>14750674
It's kind of sad that he wrote the Mars series in the first place, it became his Dune and he's been trying to escape its shadow ever since

What bothers him the most I think is that people read the books and come away with "oh that's a neat take on what terraforming Mars would look like" and then ignore the enormous tapestry of human suffering, struggle and idealism that he covered it in. The books are barely even about Mars

>>14750696
Also they got the same three or four boomer callers every damn show, calling in the same order.

>>14750718
It's literally worthless. If anything, its a cautionary tale of what not to do. You would be better starting off from scratch.

Unironically, no due to ITAR. It really would be easier to pick up a book and design your own rocket.

>>14750718
do the college or hobbygroup members have security clearance?

No. Into the trash.
