> “The one thing that I really appreciate about SpaceX is they want to move fast at all costs until they get to the crew mission," said Lisa Watson-Morgan, NASA's program manager for the Artemis Human Landing System.
> This means SpaceX is poised to launch Starship a lot. "They have told us maybe up to 10 flight tests this year, only one of which is a milestone on our contract," Watson-Morgan said.

>>15978954
> "Folks want to know how many total of these tanker flights are you going to need," Watson-Morgan said. "We’ve got our propellant transfer flight later this year. We certainly have predictions, but we'll know how much fuel is it releasing, how long does this take, are we going to be as successful as the analysis says?
>"We’re going to have to do this a few times," she said. "We’re going to have to do the prop transfer flights more than once or twice or three times in my opinion. We’ve never done this before.”
> "We’re doing an uncrewed demo, and they have to prove out their landing, and they go back up, and we may potentially have a re-landing," Watson-Morgan said. "Before we take a crew on there, they’re going to have to successfully autonomously land this vehicle on the Moon.”

>>15978958
Nitwits are going to keep asking this same tanker flight question at every press conference until 2030 arent they

>>15978992
this but unironically, though I might not partake in the sucking of cocks

>>15978982
I've made most of them for the past month, the few times I dont I believe its this current OP making them for me. I made them before but not nearly as many.

>>15978993
well no, if SpaceX demonstrates a uncrewed demo landing with then people should know what the necessary number is

>>15978992
Gott mit uns

>>15978987
Zubrin's brain is well and truly fried

>>15978998
the test landing will probably be minimum number refills with almost no payload, right?

>>15979005
i think the expectation is nasa does not plan to utilize the capacity of starship because muh margin is synonymous with muh safety in their fucked oldspace degrowth brains

>>15979003
I mean it would make sense to have mass simulators to actually test the crewed mission parameters
have mass that is the same as what the crewed landing would have, sit around on the moon for a week to test propellant boiloff etc and then go to an orbit that would rendevouz with gateway or Orion to fully test the mission as it would happen with humans
but idk if that is the plan, makes more sense to me than just landing on the moon

>>15979006
well even in that case you would have *some* mass with the astronauts and their equipment, whether that is neglible compared to just landing an empty ship i don't know
but testing propellant boiloff and showing you can actually lift off after a week requires more than simply landing

>>15978953
Ironically, the only way some of the losers on this board are getting into space is if he gets his way. (he wants to export all the plebs to space so they can mine roggs for their betters).

nobody seemed to notice this, but the NASA woman says SpaceX is planning for 10 Starship flights this year
so spacex thinks extending from 5 is trivial?

>>15979046
This! A trillion percent% THIS

>>15979046
this is engineering not science you faggot

>>15979006
It's more that Starship barfing 20 tons of payload on to the lunar surface would make the missions using the other HLS vehicle look pathetic and NASA doesn't want to humiliate oldspace.

>ten (10) orbital refueling flights to fill up 1 starship lunar lander
lmaooooooooooooooo

>>15979054
When daddy returns we'll get what we want

>>15979060
this is why elon wants to stretch it so bad I assume, but wont that also decrease payload mass to LEO? idk what the endgame is

>>15979061
Keep dreaming

>>15979060
is that actually true?

>>15979060
>starship refueling is bad because it goes against my preconceived notions of what spaceflight refueling should be

>>15979056
the other vehicle is going to land like 5 years after Starship, I don't think it really matters + they can say it has other beneficial properties that Starship doesn't have like using hydrogen which can be ISRUd on the moon

>>15979064
that is the current estimate give or take a few
subject to change of course

>>15979064
10 refueling flights to get the ship from LEO to LUNAR Orbit

>>15979071
is that with how many tons to the lunar surface?

>>15979071
I sent a fuel tank into orbit around the mun because sometimes i didnt have enough delta V to land and get back to Kerbin. I only had about half a tank by the time i got it in a stable orbit around the mun.

who knows he also ignores questions about nuclear propulsion, the some way he ignores questions about LiDAR for autonomous driving.

>>15979085
with FAA prioritizing hiring actual retards some of it seems to be true already

>>15979087
>he also ignores questions about nuclear propulsion
I also ignore most of the questions asked by ignorant retards

>>15979092
go to sleep Elon the guy has a valid point, don't that guy building shiny new horse shoes when the car is just around the corner.

>>15979085
Elon is working diligently to brainwash the masses and zoomer youth to join our cause, but it may be too late I admit. in any case we shall be free

>>15979087
he doesn't ignore lidar for driving, he says its a crutch so it actually hinders reaching full self driving
dont remember him talking about nuclear propulsion but the obvious reason not to pursue that is extremely obstructive red tape
chemical rocketry is practical now and with full reuse you can already drive costs down massively
nuclear might be useful for in-space propulsion, but that still means you would need to have some way to launch stuff into orbit i.e. chemical rockets
nuclear propulsion is not relevant right now, it is a future optimization that might or might not make sense but it would be an distraction right now

Nuclear propulsion is cringe unless you're shooting actual bombs at a pressure plate. I dont want to hear about it otherwise

>>15979099
These people genuinely need to die

>>15979105
how is it cringe do you really want to be stuck in a tin can for 7-9 months going to the closest habitable planet in the universe??

>>15979093
Shoo shoo, nuketard. The "car" would cost billions of dollars a piece and be less capable of landing a payload on Mars than a single refueled Starship while also requiring more delta-v

>>15979048
>so spacex thinks extending from 5 is trivial?
Always has been

>>15979108
Only have to make the trip once retard.
Also more mass > faster trip, and you can bet your fat ass that's going to be the optimization for the next century at a minimum

>>15979113
you're actually fucking retarded holy cow

>>15979108
That'll be 100 billion dollars plus tip, thank you. Your Blue Origin designed nuclear toaster will arrive in 40 years once the government approves the paperwork. Thank you, that will be $10,000/kg to the surface of Mars please, very effective, extremely economical

>>15979115
what nuclear fission rockets gain in isp they lose in mass fraction. sorry buddy

>current year
>idiots are still repeating the 'chemical takes 9 months to get to Mars' claim they got from old space shills
Sad

two types of spacefags

the more evolved trainautist who just likes shiny objects, big numbers and fast vehicles (based)

people who genuinely think anything gets solved by putting huge resources into going to a barren rock with nothing on it instead of fixing the already existing ecosystem we rely on everyday (coping retards)

>>15979121
t. Chicom

Enough is enough.

>>15979122
we must beat them to space

>>15979121
Once the US congress / senate breaks open the black government, the information about alien technology will be uncovered and will fix a lot of energy problems.

>>15979121
what do you mean solved? retard
its not about solving problems on earth obviously, that will happen incidentally
getting a backup civ while earth declines into the dark ages seems like a good idea

>>15979119
The only nuclear fission drive worth a shit (Zubrin's Nuclear Saltwater Rocket) would be illegal to build. I fully expect SpaceX to continue using chemical for decades to come, ultimately leapfrog fission in the 2050s and go direct to fusion as the mass fraction is similar but the specific impulse is even greater AND you get higher thrust. but that's just science fiction at this point

>>15979126
I don't give a shit about the Earth.
I just think that a Mars base is kinda cool.

>>15979121
based, beyond trivialities, space served minimal purpose in the grand scheme of scientific research, and may be a hurdle for improving mind uploading and AI on earth

>>15979121
kys heeb

>>15979126
yes there is absolutely nothing wrong with watching a rocket blow up in low earth atmosphere and then logically connecting it to this >>15979082 outcome. that is not delusional or cope

>>15979126
based low IQ anon

>>15979121
Musk promises nothing about solving problems on earth with his Mars program. All he has said is it's about risk diversification.

>>15979136
I do not need more sci fi promises, I just need someone to say "hey here's whats realistic with the technology we have and here's what the engineers think we can do in the future" that's why I respect the first type of spacefags, they know what's real and focus on that .

>>15979121
Earth should be completely destroyed, that would solve most problems.

>>15979123
Kek, surprised I've not seen this one

>>15979134
You are oozing jealousy my friend

>>15979155
is a scam

>>15979149
i just I wish i had thought of it first

OK so
/sfg/ HATES chemical propulsion
/sfg/ HATES nuclear fission propulsion
/sfg/ HATES nuclear fusion propulsion
Where do we go from here?

>>15979121
You forgot the third category of people who know going to another barren rock does nothing but getting away from the rest of our species and will throw all connections to Earth away to get there.

>>15979169
/sfg/ does not hate chemical propulsion because that includes methalox, who is feeding you these falsities and why do you believe think they are the king of /sfg/?

>>15979121
I want to get away from that ecosystem and go fuck the moon, retard.

>>15979173
i wish we knew what spacex plans are after chemical propulsion, or maybe they'll leave that to someone else. I believe chemical will remain the primary method to LEO for the next century. maybe nuclear cyclers to mars/jupiter for humans only makes sense in the 22nd century. cargo can arrive much slower like a continuous conveyor, on chemical

>>15979121
(You) and 'people' like (You) are the reason I am interested in spaceflight. To get the hell away from ALL of (You), the only place thats possible is on a different fucking planet where none of your arguments hold any weight.

>>15979169
beamed-power electric or thermal propulsion
power sails
mag sails
QI drive (trust the plan)

and chemical is the "it just werks" of propulsion

>>15979181
Theyve stated that Starship is going to be their major thing for the next century or so. Its going to be what Ford envisioned the Model T to be, absolute perfection where nothing further is needed for any normal activities. Sure its slower but ultimately good and cheap enough to be mass produced and do whatever you need. If you want anything past Starship, go suck off NASA they will be the only ones to do any of that NTP scam.

>>15979171
>>15979179
>>15979183
if you go as the first bunch of people you will obviously be forced to do whatever youre told and interact with tons of people you don't like, it will be extremely strict and you won't be able to get away from people at all. and if you go when it's "earth 2" it's just going to be the exact same scenario, people everywhere. do you think they are just gonna have you walk around outside and think about life all day?

>>15979186
beamed power from a giant orbital space laser sounds good for low mass payload (people) but the UN wont let you build one bc the temptation to turn it on them is too great

>>15979196
The UN can tongue my anus. If I'm elected President the first thing I'll do with a space laser is burn those parasites to ash.

>>15979187
Cheap is the keyword. If a market develops for faster means to Mars (for people specifically) corners can be cut, cyclers will be built, etc. If it's not economical it wont happen at scale

>>15979198
Sir you have my vote

>>15979196
The contingency plan is to blanket the far side of the moon with PV and build a terawatt scale laser array

>>15979181

wtf is the point of the space review? why do people write whole ass research papers for it?

>>15979215
i like to think of it as jeff foust's personal blog

>>15979217
yeah but he's not the only one who writes for it

>>15979051
who tf cares

>>15979219
i never said my thoughts made sense

Aren't cyclers just a meme? It likely increases the delta-v required once you include intercept/rendezvous (plus station-keeping), and it's limited to shitty ass transfer windows. The Aldrin cycler is 2.1 years per trip, everything else is like a half a decade or greater.

Do we have an idea of the altitude of the starship depot? Surely there's an optimal orbit they've worked out that minimizes drag and dV to rendezvous. They're probably going to aim for a low enough orbit that the 200t of scrap metal from a tanker+depot RUD will deorbit on a reasonable timescale. Hopefully that never happens though because that would ratchet up regulatory obstruction by several orders of magnitude, and likely doom the program to being a LEO truck for strlink at best.

>>15979213
Me? Oh no I'm not Jeff Greason
I'm uh Geff Jreason, and I come from some place far away.

>>15979223
I means you can pack your passengers in like sardines into Starship, thus reducing fees, because they only need to be there for an hour max until the get to the cycler..

>>15979223
yeah they never made much sense to me either. i can understand a permanently in space vehicle that goes between gravity wells, loitering temporarily for refuel, then is off again. not an actual aldrin cycler
>>15979227
fair enough. we've been having problems with a guy by that name shilling his fantastical propulsion methods. whines about nasa not going all in on a full scale prototype, then fades off into the shadows to work on (pontificate on) beamed energy rockets

this >>15979202 but this >>15979149

>>15979048
they're already at a 5 cadence, just with FAA sitting on them in between times

>>15979223
Cyclers make sense if you compare them to something like the NTP Mars Reference Architecture that throws away 3-12 fission reactors in heliocentric disposal orbit for every round trip. Starship enabling full round trip ship reuse with no orbital transfer of anything except propellant is a strict upgrade over the cycler design.

>>15979223
I hope you don't think cyclers are 50% on each half of the trip, because that's now how the orbits work. There's a long side and a short side of each transfer, so you need two cyclers in space for any mission other than "oh look there's Mars, wave at it while we pass it, in another year we'll be back on Urf".

this. sfg has been infested by muskbabies.

>>15979440
Theoretical magsails that do not require a coil kilometers in diameter e.g. Wind Rider pretty much require powersails (PV covered solar sails) to be developed first, of course for generating the necessary amount of power at a low mass but also attitude control (liquid-crystal panels) and course correction via ion thrusters if solar crosswind capability isn't feasible.

What I'm saying is that Japan should be threatened with a third nuke unless they fund a revised OKEANOS proposal. All the technology involved has already been demonstrated in space and it's likely the future of electric propulsion for all but the most distant planets.

Bill Nelson wasnt sworn in till May 3rd 2021. All existing senior staff were remnants of Trump's administration until after that point. HLS Starship was chosen frantically in April DURING Bill Nelson's nomination hearing, by acting administrator Jurczyck and associate administrator of human exploration Kathy Leuders, who was just promoted to the position within the last 6 months of Jim Bridenstine's term. Within the first year of Nelson's term, Leuders was demoted and ultimately left NASA, now works at SpaceX. Jurczyck died two months ago.

>>15979496

so is fission

IFT-3 will be a total success won't it.

>>15979549
I think so

>>15979549
All the way to orbit, and maybe all the way through reentry. That'd be my guess anyway, I hope it does even better than my expectations though.

>>15979549
nope, theres always something that goes wrong.

>>15979549
Its definetly possible. I hope they worked on heat shield technology though, IFT-1 and IFT-2 had so many tiles fall off both times and I think recent static fires still had same issue.

>>15979496
idk how anyone can look at IFT1 and think that it was delayed by bureaucratic concerns.
Could have launched it with the new pad in summer and it wouldn't have delayed the program.

Even IFT2 was probably only delayed by 3-4 weeks max.

>>15979556
Starship is just gonna tank reentry with half the heat shield gone. Will arrive on earth a glowing hot mess and burst into a million shrapnel splinters of steel upon hitting the cold ocean.

By the same argument shutting down the global economy would be too drastic a measure to simply prevent a few cases of the sniffles but they did it anyway, and for fucking years.

You can't apply logic to politics, especially the current politics of America.

>>15979060
What's your plan for getting 200 tons of propellant to orbit? It must be either much simpler and more robust or else much less expensive. Or does it use existing infrastructure?

Surely you wouldn't mock a plan that stands a reasonable chance of succeeding this year and changing the history of spaceflight if you couldn't even imagine a better way to do it, right? You couldn't be that stupid, right?

>>15979601
It's really hard when you have no logic of your own.

>>15979065

Nothing because no one will fund it

Also, they claim 30 days to Jupiter but it might actually be more like 100 because the magnetic field fall-off rate might be 2 instead of 1. And there's generally a lot of uncertainties remaining. Desu the more I read really, really in-depth and in the weeds about the plasma magnet and all the unknowns the less hype I get, feasibility is much further off than I thought first. And the Q-drive is a pipe dream at this point.

So what else is there for the actual holy grail of spaceflight (propellantless propulsion)?

E-sails
>EST-Cube 2 is dead because it failed to leave its payload container (ouch)
>ESTCube-LuNa is in the preliminary planning stage, years off
>NASA's HERTS (Heliopause Electrostatic Rapid Transit) e-sail is dead project never got off the ground

Solar sails
>NASA NEA Scout never phoned home
>NASA Solar Cruiser cancelled for bullshit reasons
>NASA AC3S launch on Rocket Lab later this year

And that's about it, bleak as fuck.

>>15979797
how can the magnetic field fall of rate be known?

>>15979705
No they couldn't unless by way earlier you mean a couple months at best. The launch infrastructure wasn't able to support a launch until the end of 2022. Also >muh lawfare gap, they could've kept launching Starships but decided not to and if they hadn't been retards they'd have started the PEA process way earlier so it'd have been long done once the hardware was ready. But then you can't complain about regulations holding you back so I guess Elon prefers avoidably delaying Starship if it lets him virtue signal to his new friends.

>>15979828
It can't without actual in space testing lol, cause the vacuum chamber required to properly test all these plasma dynamics and magnetic interactions would be obscenely expensive might as well just build the spacecraft at that point and launch to get that data

chemical propulsion will never work

IDK I just read it on the wiki https://en.wikipedia.org/wiki/Magnetic_sail#Plasma_magnet_(PM)

>fucking unbelievably fast
I know right.

Wish NASA had a department specifically for non-chemical space propulsion R&D, because what I'm seeing is the most inefficient, bureaucratic, piecemeal structure ever that guarantees nothing happens fast or coordinated and almost everything gets cancelled. Yet in-space propulsion should be the first priority because that determines everything else basically from bus to power to mission design (no more fucking gravity assists), basic first principles approach that NASA is not heeding.

>>15979797

You need more faith. The company behind it is never going to admit it doesn't work so they will: a) claim the data shows it slightly worked but never overcame drag. And say they have lots of data for V2 which will be 100 times more effective or b) claim some hardware failure.
And McCullough will never accept a negative result either. At most he'll just claim the company designed it wrong.

>>15980278

>>15980219
That's $750k/mo in revenue or $9M annually. There's 32 cruise lines in the world. So that's 288,000,000M in annual revenue under this model. Considering each Starlink launch costs around $40M with reused boosters, fuel, and satellite dev/integration/launch costs, that gets you 7 flights a year paid for. Sounds legit. Moreso than any other launch provider driving value.

that is pretty cool, I was wondering what a community gateway was when those pictures came up at first
so basically heavy duty starlink dishes but supposed to connect with fiber on the site or community
1.25mil upfront and 75k/month per Gigabit seems a bit steep, why would people not just personal dishes?
maybe this being a dedicated gateway guarantees better service or something

>>15980309
This does mean that cruise liners can get one of these gateways to directly mount on the top of their ships rather than having an array of individual satellite dishes somewhere on the vessel for connecting with the antenna.They already have those round mounts, which I think are satellite internet gateways. So just swap 1-2 or all four out and each ship gets 4Gbps bandwidth for a nice $4.5M, paying $300k/mo in traffic to then allow their 6.5-7k customer capacity to subscribe to, paying relatively low fees for high speed access and then using law of large numbers to make up for that difference.

https://www.cruisecritic.com/articles/cruise-line-wi-fi-and-internet-packages

The prices vary, but average appears to be around $20/day per customer for high speed wifi. 6.5k customers x 20 = $130k x 4 days for the entire cruise = $520,000 in revenue. 42.3% gross margin or $220k in profit on ISP sales PER ship PER cruise.

30 days in a month average, divided by 4 = 7 (7.5 actual) revenue opportunities or $1.54M in profit per month from 1 ship.

https://www.royalcaribbean.com/faq/questions/how-many-ships-are-in-royal-caribbeans-fleet

Royal Caribbean has 28 ships. So that's multiplying that out, that's $43.12M in profit per month across their fleet and $517.44M in profit per year across their fleet.

https://www.royalcaribbeanblog.com/2024/01/01/how-much-does-cruise-ship-cost-operate-day#:~:text=My%20estimates%20show%20that%20the,Caribbean%20is%20around%20%24208%20million.

Annual operating cost of a Royal Caribbean cruise ship is $208M. So the profit margin of onboarding Starlink gateways across all ships, would pay for essentially the free operation of 8.8% of their fleet or 2.48 ships.

Hobbitlab got part of Tranche 2.

There is also DARPA, who commissioned McCulloch’s study. The agency are no longer working directly with McCulloch but have launched a program called Otter, to demonstrate “ability to maneuver without regret,” according to budget documents.

‘Maneuver without regret’ is a key phrase in spacecraft operations. Because all current engines have a limited delta-v, any maneuver carries the risk of wasting irreplaceable fuel. DARPA are looking for something new; a solicitation document for Otter states that “Specifically excluded is research that primarily results in evolutionary improvements to the existing state of practice” indicating that they are looking for revolutionary technology.

Otter will also culminate with a demonstration in orbit, because again this is seen as the ultimate test, but even then a radical and largely unproven system based on new physics may struggle to win acceptance from the Pentagon.

They can probably pull off a miracle and get it back.

Yeah, the Nunavut government and northern Quebec are already well invested in Starlink, I wouldn't be surprised if they each bought one of those too

I choose to believe this

>>15980757
I don't understand the price /data quantity(or speed?) /month thing. $75k per month wtf

>>15980357
>>15980792 me
yeah got more context from here.

>>15980792
its for ISPs so one of these could support thousands of people, how many exactly depends on the speed offered and how oversubscribed it is which can be 10:1, 50:1 or even 100:1
singular customers just get a normal starlink dish

Thats another Earther to throw out the airlock.

>>15980810
What airlock? We're on Earth.

I made the mistake of asking some people why they don't think Mars is happening.
>BUT IT'S IMPOSSIBLE
>here are the technologies needed and what is being done to develop them, Elon's current estimate is 2028-2030.
>BUT YOU JUST CAN'T
>why
>YOU JUST CAN'T OK
>why
>ELON WORE A RED COSTUME WITH SPIKES ONCE SO HE'S MOCKING JESUS AND HE WON'T BE ALLOWED TO WIN
>mfw
Apparently the EDS crowd has a schizo faction that thinks their magic sky Jew will physically intervene to stop Elon from colonizing Mars. Don't negotiate with Earthers. Drop rocks on them.

he also won't suceed because he's one of those ebil racist trump voters
what can you do, some people are just retarded

Why does this look so bad compared to Dragon?

It's a reverse circumcision. Everything but the tip is expended.

What if you bend the tape and punch a pencil through both sides? Andromeda galaxy by 2028?

>96bn for 400 missiles
Well, there goes the Artemis Program
I guess nuking China is more important

>>15980893
Apparently they also lost the technology for ballistic missiles.

The Minuteman is so old that control system software uploads happen on 8" floppies. We are decades overdue.

>>15980900
>and as a result no nation can hack it
whats the problem, chief?

>>15980902
Your own engineers don't know how it works.

>>15980902
The problem is nobody makes 8" floppies anymore. You can still have unhackable updates with pressed optical media.
