This is with a 12 hour exposure. I honestly want NASA to point the JWST at a dark corner of the sky, similar to Hubble, and collect light for a full 100 hours, like Hubble. I really want to see what we find with that much light collected. I'd also like, not that it would happen, because NASA is retarded and won't answer questions that the entire planet was interested in for a long ass time about, but in a dream world, want them to point JWST at Tabby's Star aka the "Alien Megastructure" star, for a 100 hours collection timeframe, during its light dip period and then post the images; infrared and false color for public viewing.

Just to put that question to rest once and for all, and once again drum up hype and interest in science, space, and astronomy. But they won't do that, cause they're brain dead when it comes to being genre savvy and playing to their own audience they so desperately want to court to then get their senators and house members on board to push for more funding on.

So, what's the likelyhood of this kind of asteroid alteration working to move it to an accessable orbit? Is it reasonably feasible or would another form of architecture be better suited?

For that reason they hated it despite being the most realistic and achievable fusion design, proposed by John Slough himself. Seriously though, what happened to this? It got NIAC phase 2 funding, then nothing.

https://www.nasa.gov/sites/default/files/atoms/files/slough_niac_2014_fdr_v2_tagged.pdf

>>14658258
literally every person i've met who is into fusion rockets thinks solar electric rockets are also sick, who hates the idea of using both together? if you wanted to build a more specialized outer solar system fusion rocket you'd need to do something different, but most of what we're focused on is inner solar system stuff so that's immaterial.

>>14658315

Good morning, /sfg/

>>14658408
>does anyone have it?
No, nobody saved your shit.

>>14657820
Relies on lots of tech that doesn't exist.
Will need to be a lot of pathfinding before asteroid mining.

IMO redirecting a small (very small) asteroid into earth orbit is an amiable goal, but expecting to be able to do ISRU straight away isn't realistic.
Need to find a very small rock, that only needs a small nudge.
Could use one of those unique captures that Don't need an insertion burn to put it into earth orbit.

>>14658343
I really don't think scaling is that big of an obstacle, solar power sails like the OKEANOS proposal would not only make it relatively easy to get ample power in the inner solar system but also greatly improve the spacecraft's TWR through being much lighter than conventional panels. It still wouldn't be fast in gravity wells but that is just a limitation electric propulsion. It would be great for interplanetary missions or mining NEAs and main-belt asteroids.

Anyone have that meme that’s like “time in the aerospace industry vs anger” or something? It has the vengeful zubrin and the boomer who’s like “oh the paypal guy?”

Why does SpaceX keep trying to save Booster 7? The damn thing has been damaged so much they might as well move on to Booster 8.

so when is the orbital test REALLY gonna be?

>>14659209
You learn a lot more by trying to fix something than by just trashing it.

>>14659235
The explosion set it back a month or so. It was hoped to happen in August but also remember that SpaceX still hasnt gotten their launch license

>>14659241
it's not gonna happen this year either, isn't it?

>>14659239
I know but using a damaged booster on something as dangerous as Starship OFT-1 risks nuking the pad. Can you imagine that happening and Elon saying “we were too dumb lol.”

>>14659254
ok concern troll

>>14659251
Leakers say it’s very likely to happen this year but the factors that are of biggest concern are
1) Launch license
2) Booster static fires
Seeing as Booster 7 had issues before even starting static fires, the second might be a big issue

>>14659254
>I know but using a damaged booster on something as dangerous as Starship OFT-1 risks nuking the pad
Absolutely wrong. A damaged booster will not risk 'nuking the pad'. It either won't work at all meaning the boost won't be there in the first place or the problem only arises much later when the consequences of the damaged booster, structure-wise or fuel-wise, extend to other systems of the ship. In both cases however, you're lack of knowledge amuses me and I urge you to get acquainted with aerodynamics and engineering

Remember when SpaceX spent eight months trying to hop 150 meters but kept having issues for weird reasons and vehicle failures?

>>14659209
I never understood this expendable booster meme.

>>14659268
>>14659258
Faggot I want this to work as much as you do. Do you know how embarrassing it would be if Artemis 1 not only launches first but is perfectly successful?
I’m more worried about the Raptors being damaged but SpaceX not finding flaws until launch day

I used to make fun of JWST and the “IFLS” crowd but hooooly shit those are some beautiful pictures I can’t even make fun of them for being PopSci. We need LUVOIR ASAP

>>14659287
Did you not read the pic? Why do you assume they are clueless? They're the ones being paid to do this, not you.

>>14659301
They’ve fucked up because of oversight before though. SN9 only using two engines on landing and especially the Booster 7 boom are examples of this. The latter had Elon stating “well we didn’t think that would happen”.

>>14659297
yeah we'll be middle aged or retired when that happens

>>14659307
>2039 estimated launch date

>>14659270

>>14659287
Embarrassing for whom? SLS is still a ridiculously expensive piece of shit. It's embarrassing for NASA that they are using "legacy" tech and still haven't launched it yet. They should be embarrassed that this rocket exists.

The /sfg/ raid on Estronaut’s patreon is funny. We should do that again some time.

Forget about Elon's methane bombs, bros
A 1/4th of Ariane 6's booster stage flew yesterday without a hitch.

>>14659358

>>14659365

>>14659345

>>14659287
>Faggot I want this to work as much as you do. Do you know how embarrassing it would be if Artemis 1 not only launches first but is perfectly successful?

What are you talking about, you dumb retard? Starship ultimately will beat out SLS because NASA is fucking retarded. Their entire mission objective for the future is based Block 2 of SLS and you know what? Not only has a single Block 2 not been constructed, but it requires its own tower that also hasn't been constructed and we know from the OIG report is literally years behind schedule and already a billion dollars past it's planned budget.

Do you understand what I am saying? It doesn't matter if Block 1 is a success because Block 1 was always just a stopgap, a pathfinder, for Block 2. And it doesn't exactly take a genius to realize that Block 2 might not even fly within the next five years.

If Starship can't get up and running before Block 2, then yeah, shit is fucked but we know that is never going to be the case.

>>14659391
Could you imagine a teary eyed Tim Dodd screaming at his computer because his google spreadsheet was raided by spaceflight autists and not his usual Reddit crowd? Lol.

>>14657395

>>14659402
I wonder if he even knows about this place

>>14659401
Anon, I'm sorry to break this to you, but Block 2 will never happen.

>>14659209
We don't know that. That section of the booster has a lot of protection by design. Musk sounded a lot more concerned about cracks in the engines than the booster. The thrust puck and the shrouds probably ate the explosion and barely noticed.

>>14659411
of course he does, everyone knows

>>14659412
Exactly.

Your honor, I move to dismiss this entire retarded idea that Starship has to launch before an entirely different rocket that is already obsolete before its first flight.

>>14659130
That was spaceplane fapper specifically
>>14659412
Whether or not it happens, it WILL be paid for

>>14659365
>>14659381
Solids were supposed to be cheap. Most of the rocket is solid, except for the Slava Ucraine upper stage.

How does Elon square away in his head that they shouldn't just make an actual cargo version of Starship that's literally just a giant set of fairings, a fuel tanks, and some engines? How does he find being restricted by a tiny door acceptable?

>>14659444
The work right now is focused on getting a vehicle in orbital launchable condition.... for starlink. Reconfiguring for other loads is small potatoes.

>>14659444
What if the fairings just separate like a normal fairing would do, but instead of them being jettisoned during the ascent they do it just before payload separation, one would position them next to the ship, then wait for the probe to get away from the stage, and finally have them come back and attach themselves to starship, as if nothing had happened in the first place. they'd have some methane-based RCS and it would be like a double simultaneous docking.

What are the implications of creating a F9 second stage but the payload is just the second stage with larger fuel tanks, and then launching three of them and connecting top to bottom to create multiple in-space stages?

this concept is colloquially known as "expendable yeet train"
the main problem is getting funding and designing payload that would benefit from it
it would take a decade or so for NASA to come up with suitable mission and by that time Starship is expected to be ready and much cheaper than F9, let alone several of them

Not be a long term plan, but be able to get a significant payload to Mars or something to Europa with this method. Physically I don't think there's anything wrong with it, but I am brainlet and don't know how to calculate delta V or whatever as a hypothetical.

A small nudge might still need ISRU to get enough propellant and keeping this loosely bound dust together might be a problem on its own

Its more so they want to pull in legacy companies, as they can't make a vehicle big enough, cheap enough, robust enough for astronauts to stay on mars for a year or more due to the size of their legacy vehicles being equivalent to that of a car.

It's mostly just political, a nuclear Mars mission requiring many SLS and New Glenn launches is a better sell to congress but beyond that it seems like a lot of NASA just doesn't want to take on the risk of a manned Mars mission and it would pull funding from other areas, especially if it was a real colonization effort instead of a 30 day flags and footprints mission.

Yes yes, the radiation bit was meant to make the concerned anon look like a deboonk troll.
But "add more shielding" is always a variable in any space project even when it question the viability of further permanent base.
Elon routinely exaggerate the feasibility of his projects, knowing he can back away from his claim later (most of the time at least).

In our case, even if Starship never reach Mars it would remain a super heavy reusable launcher and the US will never ever let such things go bankrupt so it's a win-win-win-foreverwin situation.

More like hopeful.
Currently we still don't know if Starship can even work, but if it did the US would make sure to never lose such access to space.
The main reason the US didn't care much about loosing the Shuttle was because they believed SLS was around the corner and no one else could compete.
Now F9 is the new standard, the only way for manned launch and Starship would give the US extraordinary advantage.

Surely by 'cringe' you mean 'based', pbuh

>>14659683
Your first problem is that the second stage would get to orbit mostly empty, so you would need to figure out a way to in orbit refuel it.
If that's the case, it would likely be better to use a new system based around methane, so that you could use the starship refueling system and infrastructure.
If you wanted to connect them in series you would need some kind of novel interstage docking system that can withstand decently high forces.
You would also need RCS on each stage for Ullage and in order to dock them together.

IMO the broad concept of a reusable/refuelable methalox third stage for throwing small payloads (IE 1-20 tons) around and out of earth orbit is very interesting.
But I think that once you start having multiple expendable stages that have to dock with each other, the complexity and cost goes up too much, and for a 50 ton payload you are probably better off doing some kind of black buck, multiple step refueling operation with starship.

It probably would've been more clear if, instead, it was a third stage as the payload, so second stage is expended getting the ~ 22T of a third, fully fueled expendable MVac piece into LEO to meet other's of the same thing, back to back. There isn't even a payload that needs this but the yeet train could work.

The other option is using a shorter transit, which in addition to lower radiation has the benefit of lowering the amount of consumables required. Either way, it's not that big of a deal and once on Mars the radiation dose can be very low zero since an excavator can pile regolith on the habitation.

Actually I want potential colonists to consider the voyage extremely dangerous so fair weather Earthers stay home. Ideally SpaceX wouldn't do any ISRU propellant production for twenty years so they couldn't go back. Mars is for Martians.

Yes. On a side note, I hate it when people take the Oberth effect to mean that a low altitude circular orbit is ideal for interplanetary burns when that isn't the case. It's far better to be on flyby trajectory or orbiting the edge of a gravity well since you can cheaply drop your periapsis to be near the planet and you're actually traveling faster when you go to do your transfer burn. With orbital refueling EML2 straight up moggs LEO.

I don’t know why they seem to use Phi to refer to diameter, but that seems to be a thing. I don’t buy the ‘fully reusable’ meme for either diameter.

>LEO 5-150t, SSO 4-14t, GTO 7-65t, LTO 50t。

>CZ-9 is a three-stage series, repeatable, environmentally friendly and reliable, Φ10.6m, L=110m, G=4122t, P=5200t.
“P” is probably propellant but I have to fucking clue what “G” could be referring to.

>The first stage is 26 x 1961 kN thrust liquid oxygen methane, the second stage and the third stage are 4x and 1x 1176 kN thrust HO replenishment engine; LTO 50t. LEO 150t.
My first thought was that “replenishment engine” was talking about orbital refueling, but another translation for “补燃发动机” is “afterburning,” so I think it’s actually talking about the power cycle. If it’s only referring to the upper stage engines that might mean they’re looking at using something simpler like gas generators on the first stage. It’d be very Chinese to make a big deal out of having a functional staged-combustion engine in a rocket.

>But there is still a big gap between the US SLS and Starship rockets.
I’m not sure if this is a small cope over the CZ-9’s capability, or if it’s talking about the payload gap between SLS and Starship. Chinese grammar is confusing even before you try running it through a bad translator robot.

Franky I'm happy that SpaceX is testing hardware rich again. Worse case scenario, this is a 1-2 month delay. More realistic case scenario its ~1-2 week delay.

>>14660880
SLS has had its fair share of issues. The tooling for the core stage was installed upside down once. Then the first operational core stage was damaged, forcing NASA to use the third core stage for Artemis 1 instead of, you know, the first one. And then while building the third core stage for the first flight, NASA dropped one of the LOX bulkheads, rendering it useless. SLS started development 5 years ahead of Starship (2011 vs 2016).

Apparently Astra is dying now. Idk what this means but it’s bad I heard.

maybe they should pivot to satellites and spacecraft

There is a timeline where Energia was resurrected and SLS is rushed to compete

>Once the Germans came up with a good configuration for the V-2, they stuck with it. They proposed to use it anew in a two-stage missile that again sported fins that look excessively large to the modern eye, and that was to cross the Atlantic to strike New York.8 But there was no avoiding the need for a new round of wind-tunnel tests in studying the second stage of this intercontinental missile, the A-9, which was to fly with swept wings. As early as 1935 Adolf Busemann, another colleague of Prandtl, had proposed the use of such wings in supersonic flight.9 Walter Dornberger, director of V-2 development, describes witnessing a wind-tunnel test of a model’s stability.
>The model had “two knifelike, very thin, swept-back wings.” Mounted at its center of gravity, it “rotated at the slightest touch.” When the test began, a technician opened a valve to start the airflow. In Dornberger’s words,
>“The model moved abruptly, turning its nose into the oncoming airstream. After a few quickly damping oscillations of slight amplitude, it lay quiet and stable in the air that hissed past it at 4.4 times the speed of sound. At the nose, and at the edges of the wing supports and guide mechanism, the shock waves could be clearly seen as they traveled diagonally backward at a sharp angle. As the speed of the airflow fell off and the test ended, the model was no longer lying in a stable position. It made a few turns around its center of gravity, and then it came to a standstill with the nose pointing downward. The experiment Dr. Hermann had wished to show me had succeeded perfectly. This projectile, shaped like an airplane, had remained absolutely stable at a supersonic speed range of almost 3,500 mph.”
