has spacex come out with a new estimate until suborbital test since the fonsi?
I'm guessing NET november, probably into 2023

>>14591286
Elon said July, which is in two weeks

>>14591286
No. But Musk has stated they have the hardware ready within a month. But the flight license probably wont happen for few more months. So this is delay after delay

>>14591286
August as per official SpaceX spokesperson.

I've enjoyed No Man's Sky immensely, but it's not the kind of game that is easy to come back to once you are done. Starfield is looking good to me, spare for the combat, so I'm looking forward to it.

>>14591292
>VASIMR has the best t/w of electric propulsion
Wrong lmao. ELF murders it on T/W, runs on cheaper propellant (CO2 and water!), and doesn't require ANY superconductors OR cryogens. That's not even getting into the ludicrous fourth power scaling properties of the plasma magnet sail.
>and an ISP in the thousands
So do Astra's ion thrusters.

>>14591373
I like his daughter

>>14591382
I understand the superficial similarities, but No Man's Sky was an indie game from a 15-person studio that was in development for 3 years while Starfield is from a veteran studio with 500+ people and has been in development for 8 years and even has a smaller scope (not "infinite" planets and no """multiplayer"""). It's really not a good comparison.

Laser thermal is pretty good if you can sidestep the geopolitical issues of having a constellation of death ray lasers in orbit.

>>14591434

there is none

No one worships Musk, a lot of us just are inspired by him. Think of how people jerk off Bernie Sanders. It’s like that but not retarded

>>14591434
Good thing China is doing space laser power systems and doesn't give a fuck about your geopolitical narrative.

While our government debate about how to hamstrung Starship's geopolitical powers, China is doing it. While we debate about geopolitics of hypersonics fobs, China does it. While we debate about space weaponization, both China/Russia are doing it.

>>14591300

>$4.6 million for LEO carrying 500kgs
Would this be the cheapest way to launch small sats that can't use ride share?

>>14591438
The idea of "peopel worship musk" comes from the sense that Musk doesn't deserve the praises. He doesn't deserve the praises for his accomplishments because its not his and the accomplishments aren't that great. Because its not great and not his, he's a fraudster. That's the real line of reasoning behind that line of thought.

>>14591444

>>14591439
Space based solar arrays are being made by multiple countries my wumao friend, none of them use a 100 mW IR laser.

>>14591434
That plan uses a ground based laser.

Remember, Red Dragon could support a mars sample return mission.

> A mission that uses SpaceX's Dragon capsule to help bring chunks of Mars rock back to Earth for analysis could launch as early as 2022, researchers say.
> Red Dragon's robotic arm would then grab a sample from the rover's onboard cache (assuming the 2020 rover does indeed carry its samples, rather than stash them someplace) and transfer it to a secure containment vessel aboard the ERV, which sits atop the MAV.
>If something goes wrong during this exchange, Red Dragon can simply scoop up some material from the ground using its arm.
> The MAV would then blast off from the center of the capsule, like a missile from a silo, sending the ERV on its way back to Earth.
>The ERV would settle into orbit around our planet; its sample capsule would then be transferred to, and brought down to Earth by, a separate spacecraft — perhaps another Dragon capsule.

Basically, Red Dragon is big enough to hold a Mars Ascent Vehicle inside itself.

> https://www.space.com/30504-spacex-red-dragon-mars-sample-return.html

Also when do you think the first unmanned Starship mars landing is?

>>14591447
Astra are doing that all on their own, hah.

>>14591461
>ground based IR laser

Must be why it needs to be an absurd 10m beam.

>>14591442
>Would this be the cheapest way to launch small sats that can't use ride share?
Depends. Its likely more expensive to just do the legal loops to get India to launch than just to launch from the US launch companies (if you're a US company). Unless its some non-profit educational school funded project that has lots of waivers.

>>14591407
his first wife HATES Elon and that's spilling over to the litter of his kids
he's absent father, which is the best way to make your son to fuck up his life before even reaching drinking age
he also hates his own dad himself, which isn't helping things
I expect most, if not all of his kids to hate him as well

The Elon is good
The Elon is great
I surrender my will
As of this date

>>14591494
People say Elon did leave his first wife. Whether that’s true or not, I don’t know, but it’s kind of shitty.
Elon is a flawed man but I still admire him

>All this talk about Elon's personal life
Lets keep it on topic

>>14591484
makes sense. I remember reading that it wasn't easy for US corps to launch on Indian rockets because of US restrictions.

>>14591517
National security reasons exists, its so that technology from our country cannot be stolen/copied/examined/etc by another country. Look at what the Russians have done with Oneweb satellites or the German satellites. They've basically taken them as theirs.

>>14591521
And India is infamous for IP theft, exactly like China.

>>14591430
>45 day transit
>3000 isp

Not bad.

>sub 1 ton spacecraft

Ah there is the catch.

>>14591523
3000 isp is pretty bad. That’s like an ion engine desu

>>14591523
Also requires 200,000 kw nuclear power or 200 megawatts of nuclear power.

>https://en.wikipedia.org/wiki/A1B_reactor
Our nuclear reactor on the newest US Aircraft Carrier is only 125 megawatt power. So the whole thing is asking for US nuclear aircraft carrier generator on a tiny spaceship.

https://www.nasa.gov/press-release/nasa-announces-artemis-concept-awards-for-nuclear-power-on-moon
>NASA and the U.S. Department of Energy (DOE) are working together to advance space nuclear technologies. The agencies have selected three design concept proposals for a fission surface power system design that could be ready to launch by the end of the decade for a demonstration on the Moon. This technology would benefit future exploration under the Artemis umbrella.
>Lockheed Martin of Bethesda, Maryland – The company will partner with BWXT and Creare.
>Westinghouse of Cranberry Township, Pennsylvania – The company will partner with Aerojet Rocketdyne.
>IX of Houston, Texas, a joint venture of Intuitive Machines and X-Energy – The company will partner with Maxar and Boeing.

>>14591534
Lockheed/Boeing/Rocketdyne

Surprises? Nope

>>14591525
It's a roughly RL10 sized expander cycle, more akin to traditional NTP designs than an ion drive, only with three times the Isp and some mirrors instead of an onboard reactor. You could add more lasers, mirrors, and engines and increase tank volume to scale it up for manned missions.

>>14591464
> Also when do you think the first unmanned Starship mars landing is?
Q4 2024 seems achievable, the one opening q3 2022 seems pretty much impossible

Or if they just launch one without any payload and bolt on some makeshift legs, could it be possible to try landing at the next launch window already? Assuming they do t have orbital refilling working

>>14591515
Maybe.

What would it have taken for the Apollo Applications Program to occur?

>>14591523
With bigger lasers you can move more than a ton. I see this system as a way to ship people quickly avoiding 5-6 months in space with the tedium and radiation hazards that entails
>>14591525
its high thrust unlike ion drives
>>14591533
the power source stays on Earth

>>14591539
Forgot pic

>>14591464
Red Dragon was both politically dead (as senators threatned to end NASA funding if SpaceX got near Mars) and practically dead as SpaceX moved to Starship architecture.

>>14591545
Yeah NET 2024 seems achievable. Ironically, in 2016, SpaceX hoped to go orbital in 2020, and to Mars in 2022, with people in 2024.
Today, we might have orbital in 2022, mars in 2024, maybe Mars again in 2026, and then people in 2028.

>>14591544
You can move more than a ton as long as you are willing to have longer transit times.

>bigger lasers

A 10m 100 megawatt laser is already absurd.

>>14591412
I'm not looking for infinite planets or multiplayer though. It's not just about the scope, it's about the execution of said scope as well. Even if most planets in Starfield are samey, the few that have important structures on them will be handmade, while in NMS everything is procedurally generated.

>>14591464

SpaceX as a company could have ended if Red Dragon was allowed. Instead Jpl got political and now NASA rides in the back of the bus for the rest of time.

so when is the wet dress rehearsal?

>>14591585

>BO is hiring like crazy

>>14591534
why does it radiate out into vacuum instead of into the regolith? is it not easier to dissipate heat into a solution than into a vacuum?

>>14591573
What's going to happen if SpaceX manages to get their own sample return back first with an eventual returning Starship?

>>14591543
>pic
that isn't the Apollo Applications Program, that's the Integrated Program Plan (aka the Space Transportation System), which was as the name implies various NASA programs including AAP combined into one cohesive vision.
AAP was focused on continued usage and adaptation of Apollo program hardware e.g. extended apollo missions done with multiple saturn v launches, LMs modified into longer duration habitats or to deliver more cargo or carry all 3 crew down to the surface, they studied pressurised rovers and a permanent moon base. the most ambitious proposal for AAP was the manned Venus flyby.
unfortunately none of this happened and the only aspect of AAP to survive was skylab.

>>14591594
It can be placed anywhere without needing digging equipment.

>>14591589
>all the stress and fast pace of newspace with none of the payoff
no

>>14591596
no way they could have stayed 18 months without redesigning most of the hardware

>>14591596
yeah i don't think we should mourn the loss of most of the AAP LEO plans since skylab implemented most of the good ideas in those anyway but killing the extended lunar exploration program set us back probably 60 years

>>14591596
>truck
imagine the rollover incidents with a top-heavy off-road vehicle like that in low gravity and driving up and down craters on loose soil

.

>>14591595
They can't shutdown Starship if it shows proof that private companies can do it. Starlink will generate the money needed for Mars colonization project.

>>14591627
Thats a hell of a nice tug, massive boat, mostly made out engine and power source with a little bit of hull wrapped around to keep the water out. Is it electrically powered or does SpaceX prefer to use more reliable, more functional and less expensive fossil fuel engines for their transportation needs?

>>14591627
>ripping off kiwis

>>14591633
skylab ended up being pretty cheap because it wasn't designed to be a long-term space station with replaceable experiments or resupply, which was good because that was the only way for it to survive the budget crunch. we could've sent more missions to it, sure, but i'm not sure they would have been of any practical use other than the prestige battle of saying we have a bigger station than the salyuts. never following up skylab with a long-term 10m station, on the other hand... that was the real fuckup

>>14591632
>F-35
>garbage

Look at this anon and laugh.

>>14591319
the REAL Orion would have nominally been between 12 and 30 meters in diameter
the larger diameters would have used more powerful bombs

>>14591633
I've always liked the plan to resuscitate Skylab for the Shuttle era. It's a pity the Shuttle ended up being far too delayed to see it through

>>14591620
there's another way

>>14591620
i don't think it was supposed to be a 'truck' as far as driving around as much as it was just designed to land cargo on the surface and carry a lot more than a normal LM since it didn't have to bring propellant for ascent

>>14591633
>>14591644
>>14591672
Skylab B bros...
we had a whole fucking space station and enough spare saturn hardware available to launch it but instead let it gather dust in the Smithsonian

>>14591644
Why is it illegal for NASA to choose a Starship and launch them to orbit and have those 1000 cubic meter, a 1 cubic km, as a reusable space station that can be refueled, modified in space, change orbits at will, land back on Earth when finished, dock with other Starship in orbit, etc for cheap?

>>14591690
>reusable space station
sissy shit
MOLchads rise up

>>14591690
The mistake is thinking that the path of least resistance for them is simpler, cheaper architectures. In reality the way NASA persists is by including as many states as possible in its supply chain. They will never consolidate their supply chain like that.

>>14591699
MOL was fuckin weird. Badass, but weird. Imagine making a space station and throwing it away every month lol. Pic unrelated.

Honestly what if NASA decided that the shuttle was too expensive so they just continued using Apollo for LEO taxis.
Maybe they used the extra budget to fly one lunar mission per year. So the moon becomes like the ISS is today. Maybe in this timeline, people complain about the Lunar Base taking interest and money away from mars. Lol.
This could be feasible right? Like there’s no way developing and flying the shuttle was cheaper than 1 Saturn V flight per year over 20-30 years?

>>14591712
>Imagine making a space station and throwing it away every month lol.
imagine making a spacecraft and throwing it away after each flight

>>14591729
>Like there’s no way developing and flying the shuttle was cheaper than 1 Saturn V flight per year over 20-30 years?
in hindsight, you are probably right
but nobody could have known how awful shuttle will be at the time

>>14591729
sure, never would have happened though

Big Gemini/Blue Gemini is an interesting road not traveled. USAF even flew a Blue Gemini prototype that was a refit and reused Gemini capsule.

>>14591730
>imagine making a spacecraft and throwing it away after each flight
That's just Soyuz

Apparently the Orion for Artemis 1 is being scrapped and reused for Artemis 2. That’s why Artemis 2 is NET 2 years after Artemis 1 lands

>>14591911
There are many ways to get into scifi. Just use the imagination as the base. Imagine how a world would be in your head, imagine how the society would work in your head, draw them out on a paper. Write out on a paper how the society would function. Flesh out the details. Imagine the technology that would be available. Flesh out the details.

Then think of a narrative, a story that you really want to tell. For example, you could write a story about a man who wakes up in this universe. Explores the world through the eyes of a "novice" (a self insert for the reader to engage with) but only to find out that he's just a special case of a cloned body that has gained consciousness through a mishap/error in cloning process. The error rate could be 0.000000001% but on this futuristic society, with trillions of clones, that would mean handful of special case are born each year. You could explore the society through such a way that draws in the wonders of the sci fi world that you imagine and the horrors from which the newly established cloned human would find himself in. The society could be made of cloned humans with mind transfers and all the "normal" people could have lived for tens of thousands of years and follow a social rule that is completely alien to a "normal" sentient born clone like him which has to start off from fresh without any support. He could be treated as a child in the society or a paraiah or a test subject to be studied. The society could be completely benovelent to the point of being completely alien from the "normal" person like him.

the saturn v production lines were designed to pump out 6 rockets a year. if they tried cutting it back to 1 they would've had to invest some money in reconfiguring things for a lower rate, but in retrospect that would've been well worth it. good luck selling anyone in 1971 on the idea, though.

>>14591932
I know this is more /tv/ and /k/ related but wouldn't moon dust quickly fuck up to all hell the intricate mechanisms of atmospheric firearms? And that's not counting the risk of the brass cases cold welding to each other in vacuum because some ammo autist would have cleaned the cases before loading them.

>>14592673
>>14591819
>simply extend the cone
for some reason I find Big Gemini extraordinarily funny

>>14592685
It would likely drastically decrease the service life of the weapon due to abrasion, but I doubt that sealed designs like the AR would immediately encounter issues functioning due to small amounts of moon dust getting into the action.

>>14592678
It'd probably be fine the way it's laid out in that gemini image; the axis of acceleration is perpendicular to the torso. Cope suborbital gave up because the thrust axis was parallel to the torso/legs which sucked all the blood into the feet even with an anti-g suit. Also, it takes a lot more Gs than gemini would ever see to break bones or else fighter pilots would die every time they made a high AoA maneuver.

https://ntrs.nasa.gov/api/citations/19980223621/downloads/19980223621.pdf
When the direction of acceleration is perpendicular to the spine, trained pilots and astronauts can withstand up to 10 Gs for a minute without suffering G-LOC. At 6 G the average male pilot (not trained for High G resistance) from the 1960s could stay conscious for 10 minutes, without any external assistance like leg compression or a full anti-g suit.

While it doesn't relate to long-term G tolerance, this Air Force test pilot survived over 60Gs without any long term injury
https://en.wikipedia.org/wiki/John_Stapp

>>14592685
Cold welding isn't much of an issue because the amount of surface contact between two parallel cylinders is minimal and spontaneous cold welding is actually quite rare even between similar/identical metals. The only major example of cold welding actually causing an issue is with the Galileo high-gain antenna. contact welding is much less likely to occur when there's any sort of contaminant present such as oils, else ball bearings would be useless in space.

Moon dust wouldn't be much of an issue because there's no atmosphere to suspend it so it's all on the ground... unless you dropped your rifle onto the ground in which case it could potentially be a very big issue. ARs are very dust and grit resistant assuming you keep the dust cover closed, but an AK would probably jam the second it touched lunar soil.

>>14592718
IIRC the highest Gs survived by a human is like 214g but for a split second. https://www.youtube.com/watch?v=aVpux5JxqEk

Thanks for the explanations. Funny to think that in such an hostile environment for man, the AR is actually the best platform.

>>14592535
>I wanna know if a perfectly vertical F9 launch could surpass the moon
An expended Falcon 9 can get 8,300 kg to GTO which should have an apogee altitude of 35,786 km, although sometimes rockets go higher because the inclination change to GEO is cheaper. Just as a reference that's about 680 m/s short of a trans-lunar injection but I can't find the payload stats for that. Using a rocket that has roughly the same delta-v as that requires and launching straight up from Cape Canaveral into the plane of the Moon results in an apogee altitude of only 1,500 km, so not even close. It's hard to see but the little blue line is the trajectory.

This is why rockets don't just fly straight up. Just circularizing this would require 4200 m/s of delta-v which is more than what's required to reach GEO or escape Earth from a LEO parking orbit.

>>14592044
>Take the low road!
>Not that low!

>>14592748
Just ran another test with a rocket that has much more delta-v, Falcon Heavy could reach escape velocity despite how inefficient it is to fly straight up.

Zubrin is a retard and his argument was indeed a strawman which mostly just deboonked fast Mars transit NEP due to the need for a reactor far lighter than what can be made in reality, but VASIMR itself has serious issues that aren't being addressed. If was just slow to develop and it just had mediocre performance compared MPD or even a modern gridded or hall effect thruster it would be one thing but its longest test was only 88 hours which for electric propulsion is the equivalent to a rocket engine that can only fire for a second before shitting itself. NEXT for example had a 48,000 hour test before being demonstrated on the DART mission. I think this is enough for it to be rightfully considered a scam outside the whole 39 days to Mars thing.

Is this also true for JWST? Could they have built a better telescope for less money?

>>14592957
They haven't had enough time to really try, because everybody thought booster reuse on this scale was bullshit. Even on the first landing, even on the first reuse, the whole industry was screaming that it couldn't ever work, wouldn't ever be worth it, because if that were true, they'd need to get off their asses and put in real effort to compete.
Even now the denial is strong, and oldspace will just slowly die, taking smaller and smaller contracts for less and less relevant projects until they wither.

>>14593035
It has taken them 39 years to reach that duration and NASA gave them a goal of >100 hours so I find it hard to believe they pulled the plug early without reason. It may not have an electrode but it's far more complex than other thrusters and it could easily fail. Even if they get it working, what then? There's no 100 kW power source for it to use on a demonstration mission and there are already thrusters with greater N/kW and/or higher Isp. By all appearances VASIMR seems to be an episode in sunk cost fallacy.

The power requirement is the catch. You would need tons and tons of solar panels to run these for any length of time (1.2t is about 31kW if you use a piece of the ISS solar arrays). Or a nuclear reactor, though I'm less confident you could make one small enough to use with these.

Electric propulsion is generally measured in mN, a few newtons would be great. For now Mars is firmly chemical territory but when you're traveling for years you want to maximize specific impulse at the expense of throost.
>>14593189
The horrid mass of a fission reactor has always been the major issue with nuclear electric. State of practice solar is at least an order of magnitude better in terms of specific power at 1 AU, with power sails it could be two orders of magnitude better and enable really quick transits. "Mars in 39 days" would be possible and it's far less political than laser propulsion.

If there was an economic incentive for it, yes. But telescopes aren't known to be profitable. I can imagine someone semi-mass producing telescopes around Hubble's power (I don't know if that's a lot by modern standards, but Hubble is old, so I assume it's fine) and selling them to astronomy organizations and space agencies, but this is just my imagination, I have no idea how feasible something like this is.

Trying to do something new also has a chance of failure, and nobody wants to be the guy who failed, no matter the payoff at the end.

The worst part about this is the service record for falcon9. It was understandable to be skeptical but now...

Hubble-class telescopes *were* mass-produced, by Lockheed. The NRO/CIA/NSA have ordered at least 20 of them - at least 17 (there are 2 NROL missions with unknown payloads that were almost certainly new KH-11s, launched in 2019 and 2021) have been launched; 1 or more are mothballed in case of unexpected loss. HST is built on an over-provisioned KH-11 chassis that was given stripped down to NASA in the 80's, and retrofitted for deep-space observation instead of earth reconnaissance.
The actual optical capabilities of the KH-11 are still classified, but from what was gathered from the images Trump leaked it seems they're significantly better than the HST (with the caveat that the instruments are likely only visible-spectrum and for deep space observation you want near-mid infrared).

One hundred and twenty five LANDINGS. Just the kino alone has been worth it.
(and another 25 or so more launches before landings worked)
It's had more missions fail due to payload failure than launch vehicle failure.

And wtf, someone lopped off the first 77 launches from the Falcon 9 launch list page on wikipedo? Hmm, according to the talk page, it got too big for the soi visual editor to handle it.

Never said anything like that.
But if you want everyone to excise for 1h a day, that means you need minimum of 1 resistive machine per 24 people, if you put people on strict shifts.
For 100 people you dedicate a full fledged gym.

Thats what CGI is.

That's actual cope, it's physics that would make the JIMO reactor so heavy that it could be beaten by solar even at Jupiter. If nuclear supporters weren't deranged they would argue for beam-powered propulsion, which could enable outer belt colonization without requiring gorillion dollars worth of reactors.

Their successful webb launch cemented this thing as a legendary launch vehicle. It's outdated and far too expensive to operate at this point, but it's still damn good.

>The House bill provides $7.32 billion for deep space exploration systems, about $155 million below the administration’s request. However, the bill specified funding for the Space Launch System, Orion and Exploration Ground Systems at or slightly above the request. That means the cut would be absorbed by other exploration programs, such as the lunar Gateway and Human Landing System.

All must be sacraficed for the jobs program.

In common vernacular CGI = Fake 3d art. 3D models implies it's based on some kind of data model. It's the difference between the incredible hulk, and rocket graphics. One is total fantasy, and the other is a representation of a real thing, based on data.

>>14593893
I warned you bros

>>14593895
just because you use the term wrong doesn't mean it has a different meaning than the meaning it has. Any rendered image assembled using a data file of triangles and vertices projected into a virtual space is unambiguously CGI.

CGI/3D models are representations and not the real thing

This fag thinks the hulk is real kek

>>14593919
Movies are like that, they're a replication, a fabrication, meant to show a sense of realism, but is ultimately not real

>>14593913
anon, it's ok that you've only ever encountered the term "CGI" on marvel movie discussion forums up until this point, but it's unpleasant when you double down on the wrong side of something so easily googled. Part of growing up is accepting that you learn new things every day and it's not a personal failure.

Do they not realize that SLS is useless by itself?

>>14593891
no need for them, this is what we're sending

>>14593950
Anon you seem to be making the mistake of thinking they care what SLS actually does beyond being a means of getting money for their districts.

It has been a long year of craneing cillinders around.
When is Elong going to admit Starshit is a corporate scam?

>>14593908
How so? It would be less of an engineering challenge than other fast transit designs and it wouldn't require material science wizardry, it's just getting to Mars quickly isn't particularly useful in the short-term and long-term beamed-power is superior. For this reason power sails are more for planetary exploration and they would be hard to scale up to the sized required for manned missions far from the sun, for low cost probes they could be unbeatable.

The "interject" copypasta is not a joke. It's a comprehensive summary of the SLS as a whole. It could be used as the preface to a textbook on SLS (assuming you could split the writing of one into 50+ congressional districts).

New SpaceX project "echo" near Boring Company. Possibly something to do with Starlink satellites, possibly related to radar technology?

Err, reading the paper, it looks more like possible internal SpaceX communication links using Starlink or some other sense.

Titan is cool but the lack of metals and resources on the surface make permanent colonies kind of difficult. Mars is arguably better.

Zubrin is already on Mars. He's waiting for us.
