First for cute girls going to space!

I'd just like to interject for a moment. What you're referring to as Orion, is in fact, SLS/Orion, or as I've recently taken to calling it, SLS plus Orion. Orion is not a launch vehicle unto itself, but rather another multibillion dollar component of a partially functioning pork system made useless by the SLS subcontractors, shitty designs, and Alabama river rocks comprising a gigantic scam as defined by the GAO.

Many taxpayers fund a small part of the SLS scam every day, without realizing it. Through a peculiar turn of events, the version of SLS which is widely mocked today is often called "Orion", and many of its victims are not aware that it is basically the SLS scam, developed by the SLS lobbyists.

There really is an Orion, and these people are seeing it blow up, but it is just a part of the scam they fund. Orion is the capsule: the payload in the system that allocates the government's resources to other districts that need pork. The capsule is an essential part of a launch system, but useless by itself; it can only incinerate astronauts in the context of a complete launch system. Orion is normally used in combination with the SLS boondoggle: the whole scam is basically SLS with Orion added, or SLS/Orion. All the so-called "Orion" debris fields are really distributions of SLS/Orion.

Friendly reminder that NTP is happening this decade whether you like it or not.

What do we know of Firefly's Miranda engines that will be used on Antares? The RD-181 engines previously used were pretty much the best kerolox engines out there and even then the Antares had shit performance. Unless the Miranda engines are some high performance ORSC engines they would have to replace that garbage solid booster upper stage just to reach orbit.

>>14741909
I'm sure Miranda performs worse than RD-181, but they'll get better performance out of the rocket by scaling the stage up.

>>14741957
fat core Antares looks... off
it's like Delta IV medium with a small fairing

>>14741957
so based. will Antares 330 fly before New Glenn?

>>14741957
Ah, so they're basically replacing the entire first stage.

>>14741909
It’s got a vacuum isp of 302, so it’s almost certainly using a gas generator instead of staged combustion. With just over 1 kN of thrust it looks a lot like modernized equivalent of the RS-27A.

Over for Firefly, probably. It’s actually kinda fun watching Northrop wind up to anschluss another aerospace company.

>>14742022
Are you pretending to be retarded? USA was first to send people to the Moon, USSR has never done that.

>>14742024
no it says USA won

Arguably the USSR walked away from the space race with far more benefits than the US did.
Apollo missions were pretty scientifically scuffed, the retrieval of lunar rocks being the main scientific benefit of the program. The problem that the US had was the fact that US rockets were too expensive for continuous manned flights. Skylab only had three missions before it was abandoned, though it was planned to be boosted with the shuttle.

>>14742031

I can't wait for the day those 3 just stop existing.

percy caught a martian hair and /sfg/ doesn't even care

>>14742034
>though it was planned to be boosted with the shuttle
There was a good chance that the Shuttle would have been used to intentionally de-orbit Skylab over uninhabited territory rather than boost it since many at NASA thought a revived Skylab around would jeopardize their chances of getting a "true" space station funded and built

>>14742038
As much of a shitshow as they are now, I could see Astra doing better as an IP under a big defense industry player. Rocket 3 costs about the same as a tomahawk cruise missile which presents some interesting possibilities as a prompt global strike system. They just need to get a 2nd stage that’s actually reliable.

>>14742038
dont forget BO gets Relatively. Even Bezos himself toured the factory, clearly an interested investor. sadly no one wants rocket lab. just not glamorous

>>14742063
I could actually see Relativity either fighting off a takeover or getting eaten by a larger non-space launch company. If you can print the first stage of a Terran R, you can also print the fuselage of a Douglas DC-8. There’s got to be a lot of people that’d be interested in buying that kind of capability that aren’t involved in building rockets.

>>14742054
wait there's animals as well as plants up there? woah

>>14741909
berger was saying they'd bought a few f9 flights for cygnus too so they aren't expecting them to be ready for a while. anyone who knows how these things go can expect that they'll have to buy a few more before the new antares is ready.

>>14741718
Instead of wasting time here shilling and being a faggot as per usual, you should use your autism for good and make a diagram that would break down the various nuclear development efforts.

>>14742059
They also have god-tier avionics.

>>14741999
The US made the moon the goal because they figured they could "win" if they set a goal and pretended that is what it was all about.
The sad fact is humanity lost because both nations where more focused on firsts instead of building sustainable LVs. Even when all the money was already spend and the Saturn V produced the MLVs were canned because politicians couldn't see any point launching huge payloads now they has "won".

Hi anons, are there any aerospace positions who have remote work + no ITAR/citizenship requirement?

we reached 100 launches so far this year

>>14742303
There's plenty of small startups focused on payloads. Generally the more software development ones will be remote work.

>>14742357
can you name a few companies like that?
im good with programming, bachelors in aerospace. But not american, so looking for remote work.
I desperately want to work with anything space.

>>14742364
I did check out the more well known ones but they had ITAR requirements.

If anyone is thinking of getting a L2 subscription, do it only if you want to donate. Take a 2 month for $20 and then if you think its worth it, you can take a $200 one.
I didn't feel it was worth it so stopped after step 1.

Closest anything gets to this is Stellaris, but like all modern 4X games it devolves into a glorified spreadsheet simulator after an hour or so of gameplay. You basically never see good strategy/tactics gameplay combos anymore.

Truth. I think a big part of early spaceship construction will be figuring out how to do welding in space. Once they figure that out, I think they can send up stacks of beams/hexagon/pentagon/triangles and have robots weld them into massive pressure vessels, trusses etc.

>>14743745

>>14743745
Welding is extremely easy in space, you don't even need to create an inert gas bubble around the bead as the metal isn't going to oxidize.
It's so easy spacecraft designers have to actively design against it https://en.wikipedia.org/wiki/Cold_welding#In_space

>>14743745
>>14743755
i sort of agree. welding in a vacuum is well studied topic and bead dynamics are mostly dominated by surface tension and not gravity.

Relatvistic Bussard ramjet warships like in Protector by Larry Niven:-

A directed magnetic field would churn the interstellar plasma as it was guided into a Bussard ramjet. As a weapon it might be made to guide the plasma flow across the ship itself. The gunner would have to vary his shots, or an enemy pilot could compensate for the weapon’s effect. If the local hydrogen density were uneven, that would hurt him. If the plasma were dense enough locally, the enemy could not even turn off his drive without being cremated. Part of the purpose of the ram fields was to shield the ship from the gamma ray particles it was burning for fuel.
“Hit him near a star, if you get the choice,” said Brennan. “And don’t let him do that to you.”
The laser was surer death, if it hit a ship. But an enemy ship would be at least light-seconds away at the start of a battle. It would make a small, elusive target, its image delayed seconds or minutes. The thousand mile wings of a ram field would be easier to hit.
The guided bombs were many and varied. Some were simple fusion bombs. Others would throw bursts of hot plasma through a ram field, or carbon vapor to produce sudden surges in the burn rate, or half a ton of pressurized radon gas in a stasis field. Simple death or complicated. Some were mere decoys, silvered balloons.
Brennan was throwing everything at him. The Pak scouts had used a three gee drive until they crossed his wake, and then Wham! Six gees and closing. Some of his missiles were going wild; the scouts were doing something to the guidance. The pair dodged his laser with such ease that he’d turned the damn thing off. They’d used lasers on him, firing not only at his ship but at the field constriction behind him where hydrogen atoms met and fused, so that Protector surged unevenly and he had to worry for the generator mountings. They threw bombs at unreasonable velocities, probably through a linear accelerator. He had to dodge in slow random curves

>>14742034
It's incredible what's achieved with that technology.

Humans went from horse and buggy late1800s to wires and electronic computer metal box machines blasted into space, with such trust in what we see as rustic technology, barebones, simple, sparse, pretty remarkable.

This is cool idea too

Different players play as society of people in the future who live on the different planets, and they have to do tasks and games and city building, mini games, then a mode can just be fighting mode like forrnight and cod on the scale of flying between planets and using large scale weaponnry and defensive strategy, doing activities, winning mini games getting earnings that you spend on covering your planet areas you can afford and moon, with different offense and defense and satelites;

And this can possibly be large teams of like 20 or more people as a team member of this or that planet; and and then they take to planes and battle in the sky and try to bomb the other planet, and/or defend the home planet from the other teams incoming attackers;

This could possibly be an online game with each planet team consisting of 100s of possitions;
Players can leave, and their character can be picked up by someone who wants to enter the game;.

All that plus this are pretty great ideas;>>14743913

This view of orbiting is incredible.

It's just crazy to see this steady flowing, or talking toward earth, but it in lockstep falling away from it. Just how consistently this works, the camera is just flying there, and getting sucked and drifted and caught up by and with and dragged and curled and soared and pushed and pulled and pressed and forced, and its just steadily working the same orbit path?

Or every so how often there is some thruster to shoot up and to lock for a while in a higher rush of gravities gasues liquid metal river? But only a little thruster energy to change lanes into a higher orbit?

Reading the manga that someone here recommended the other day. First raised an eyebrow when the MC said they needed to develop liquid core nuclear thermal for the asteroid redirect and nothing else would work. Then seeing the depiction of it, holy fuck, what was the author thinking?

What would it be like keeping starship locked in orbit around earth? And it can be outfited to be a station?

>>14744202
They completely changed everything in the design multiple times since they still needed to wait for launch approval anyway, skipping static fires since those are more for operational testing than designing when it comes to doing them while attached to the vehicle.

Which isn't much because 18 ton engines and massive liquid hydrogen tanks don't make for that good of a spacecraft despite the ~850 second specific impulse. Instead of acknowledging the downsides of nuclear thermal and the limited mission opportunities with just a modest increase in delta-v, people would rather craft conspiracy theories. Literally every single dollar going into nuclear thermal would be better spent on solar electric, beamed power, or fusion.

I saw no tiles fall off. This might actually work.

The US military wants NTP and they're going to get it. The near future will probably turn out like marine propulsion where tech for militarized nuclear drives remain closely guarded secrets and it doesn't percolate to the civilian markets because 1) fuck off, it's secret and 2) it's not economical.

A traditional format of honor duel in Lunar society is known as the Hot Staff. The participants are both armed with a thin staff that is tipped with a red-hot ball of encapsulated plutonium, and the goal is to overheat one's opponent until yield or death. The Hot Staff may be carried out in pressure suits in the hard vacuum of the surface, or bare-skinned in a habitat environment. The former is generally a slower contest of strategy and endurance, while the latter involves ample sizzling flesh, and draws larger audiences.

>>14744480
What they're going to get is a limited amount of small solid core NTP engines that can be paired with spy satellites which can then do large inclination changes to get into position, at the expense of reliability, longevity, and of course cost. As much as people here claim it's inconsequential, the Outer Space Treaty will mostly prevent the militarization of cislunar space, an area where chemical propulsion faces few obstacles and higher delta-v doesn't do much to reduce trip times, especially once factoring in the lower thrust of higher Isp propulsion. The military would be wise to ditch their sci-fi influenced ideas and love of anything nuclear to instead learn that space is a game of economics, logistics and infrastructure.

You appear to be confusing Orbit with Galactic, the latter being suborbital tourism.

>>14744452
High weight high ISP is only good for pushing big payloads to big speeds.
If you want to send 100 tons to Mars docking with a NERVA in LEO for the TMI burn makes perfect sense, if you want to send a 5 ton payload like Curiosity it's a waste of time.

>>14744653
nta, but I don't think he's confused at all
virgin orbit IS fully irrelevant

>>14744637
"Flexibility" in lifting 500 kg payloads for 12 million isn't worth much, all those countries are US allies who could ship their payloads to the Cape for integration or use their own launchers.

>>14744452
>Which isn't much because 18 ton engines and massive liquid hydrogen tanks don't make for that good of a spacecraft

Modern NTP engines weigh less than 3500kg.

Having double the ISP means you can carry at most half the weight of propellant, when the bulk of your crafts weight is propellant this is a significant weight savings.

>>14744659
>basing your NTP specs on NERVA

Anon it isn't the 1960's.

>>14744556
>the Outer Space Treaty will mostly prevent the militarization of cislunar space

It hasn't stopped it so far because the only thing it prevents is nuclear weapons in space.

>an area where chemical propulsion faces few obstacles and higher delta-v doesn't do much to reduce trip times

The military isn't interested in very high delta V to reduce trip times, it wants to be able to make large orbital changes multiple times.

>>14744686
>nuclear weapons in space.

>>14744674
Did reactors get small and light while I wasn't looking? Sure you could ditch NERVAs shielding if robots fueled, transported, mounted it in the fairing and you are 100% sure it's not going to explode but the fuel rods are still going to be heavy.

>>14744536
isn't that what they're giving it by not rushing the other launches?

>>14744703
Reactors did get smaller and lighter compared to the primitive designs of more than 50 years ago. NERVA was also not an optimized design, its job was to prove the concept.

>>14744536
Astra couldn't get a fucking pressure fed engine to work reliably.

>>14744536

>>14743791
he pitched the idea with NG in mind because BO is building space station and Bozo expressed interest in orbital construction rather than planetary colonization

refuelable NTP makes sense from a logistical perspective, hence why the USSF is interested in it.

Whilst for a single use spacecraft it doesn't offer a worthwhile performance benefit over low drymass chemical set up, for an orbital ship that regularly makes maneuvers over say a 10 yr period, it massively reduces the mass of fuel required for refueling, which all needs to be lifted out of earth's gravity well.

ok but how *many* days? weeks? months?

Just hurry up and launch it already, you're up to building ship 25/26 now anyway, it's not like you'll run out soon

>>14745344
>The loaded LH2 could also be increased to support boil-off over the desired 90 day LEO stays
or
>The study shows that efficient passive cryogenic storage for periods up to a year is feasible with proper system design coupled with key thermal isolation technologies.
With rapidly flying rockets, this becomes even more of a non-problem. Just launch some more hydrogen if it boils off.

It bans all weapons of mass destruction which could easily include kinetic bombs, high power lasers, open cycle nuclear, etc. You could get around some of that restriction by pretending it's for civilian use like with SBSP which the Chinese are interested in, but still military activities in space are quite limited.

>>14745217
There are criticality limits which means you can't get much lighter than that, most of those designs use highly enriched uranium which the government has insisted won't be put into space, and a Pewee class engine would use a 2 ton shadow shield. Anyway you shake it the total TWR is much worse than chemical.
>significant weight savings
At the expense of less dense reaction mass and many MLI layers to prevent long term boiloff. It's simply not hard to move very heavy payloads around cislunar space, the delta-v requirements are relatively low and depots are easy to create. You'd be crazy to greatly increase cost just to increase the payload of any one rocket.

>>14743994
the whole point of starship is that its rapid reuse lets it hurl retarded amounts of mass into orbit
it has a fuckton of equipment that's only good for that reuse
by making it a station, you throw away all that and get a mediocre station with unhelpful shit taking up space
