>>12417319
A major coronal mass ejection vaporizes every artifical satellite in Earth orbit at once, and makes modern electronics too unreliable for the Shuttle to fly for the next five years. Big G plus MOL on a rad-safe Titan is the only reasonable way to get our eyes in the sky back ASAP, and the Soviets know it. We eventually get stations "accidentally" encroaching on each other's orbit and EVA raiding parties with special vacuum modified M-16s and AKMs. Space war to the knife.

Oh it definitely would have worked, it just would have never been able to achieve the levels of reliability that other rockets like Soyuz have, at least until they replaced the engines with a design that didn't use pyrotechnic valves and also moved the production factory to within a few kilometers of the launch site.

that's a good point. Chemical engines' strong point is thrust, not isp. Sacrificing the former for a mild gain in the latter is kind of defeating the point. Better to use different tech altogether for deep space instead of using a gimped chemical engine.

I just threw out those numbers as an example. My point was that there's no way SpaceX would need more than a billion dollars to profitably develop a new, small, hydrolox engine using technology that they mostly already developed for Raptor. Also, even if each engine only cost SpaceX ~$500 grand to build, they could of course charge $10 million to whoever was buying it. Eventually SpaceX would likely become their own biggest customer for this engine anyway, since there are real reasons to use hydrolox propulsion in some scenarios, just not for Earth launch in particular.

>>12417390
Design is a tricky thing. Engineers often fall into philosophical traps that end up making shittier designs that are good in one or two mostly irrelevant ways (Every gram at any cost, minmaxing operational reliability, etc). Pyrotechnic valves are a good example; you know with 100% certainty that the valve is gonna work when you send the electrical signal. However, the engine can't be tested, and there's more to an engine than just a series of valves. Therefore, the risk actually goes up, because you are banking on the hope that none of the impeller blades have a micro fissure and none of the injector holes are plugged up, etc.

Engineers can end up wearing blinders, the entire aerospace industry inherited the mantra of designing things to have as little mass as possible from the Apollo era when it actually mattered, and kept it alive universally until the mid 2000's when SpaceX realized that if they made the rocket bigger and heavier, they could fit in mass margins that allowed for reuse, which could make everything launch more often and more cheaply.

I just don't see any scenario where SpaceX would want to be a supplier, especially not for anything that takes dev time off of Raptor which will continue to be in constant development probably until Starship is to be retired for the next big thing, like Merlin. The value return for Raptor is in running the vehicle that will obsolete most of their competition, while making themselves a supplier is specifically for the purposes of propping up that competition. Whatever the returns they get on it, it will be a ridiculously small part of their business and entirely a charity to the incumbent industry.
I don't really see it happening as an internal project either. What's the place Raptor doesn't fulfill for them that a hydrolox FFSC would? I can only see it as a Lunar ISRU engine, which I don't think is in the cards for them.

Sounds like the kind of thing supersonic deposition metal PROOONTING might be quite useful for. You'd need a combustion chamber with two distinct sets of cooling channels of even number and separation from one-another and I think ideally a fuel and oxidizer of very close temperature ranges (like LOX/CH4) because otherwise half the channels would be much colder than the others and that might cause it's own set of mechanical stresses in the engine.
I can't really imagine it being practical with conventional fabrication techniques.

Here's an older video from the SPEE3D printer, now obviously you'd need a great deal more precision for a rocket engine, either the process would have to be slowed down, or the idea I had was to create a rotary deck of different toolheads at different precisions as needed. The armature is also not as precise and steady as others I've seen so a replacement of the armature with one that's more stable would also likely greatly increase build quality. There would probably also still have to be some finishing work, but of course that's true for all fabricating processes.
SSDP is also going to be great for sheer manufacturing speed, even if it has to slow down to be sufficiently precise for aerospace, imagine what a process like this could do in eleven hours instead of eleven minutes. Give it a whole day and it might very well be able to create most of an engine from scratch.
Metal printing, when properly matured gives you exactly that kind of capability for extreme internal complexity in a single homogeneous piece of metal, thus also saving on part counts.

it's kinda moot because in the first world the vast majority can't see shit thanks to light pollution, a far larger problem, anyways.

I've worked in a place that made parts for aerospace. 3D printing right now is used as a way to make people come see your booth at conventions and meets. We actually produced the first flown chain produced 3d part and it was just some 10cm pipe with a dogleg shape.
3D printed metal isn't mature tech. The shape of the part is limted by how the printing is done. The mechanical properties of the produced part are inconsistent part to part. The size of what you are printing is severly limited. The costs are prohibitive.

Don't get me wrong I think 3D printing is the future (the old fucks at my job hated it with a passion though since it directly threatens their jobs), it's just not ready to do stuff like print huge parts or parts that are supposed to be aerospace rated.

first, that SPEE3D printer is never going to print anything precise, it really looks like convention bait. The point of 3D is making shapes you can't with conventional means, like latticed structures. SPEE3D isn't going to be doing those.

To make precise parts with 3D printing you have to make a flat layer of powder then blast it with your laser where you want fusion to happen. The limits to build quality are laser precision and how fine your powder is. The costs are prohibitive because in a single batch of powder about half of your powder is fine enough and the rest is rated as too coarse to use for aerospace part.

1. water doesn't get radioactive, neither oxygen nor hydrogen will turn into anything bad even if you bombard them with thermal neutrons. Oxygen turns into Flourine via beta decay (quickly) if you get it all the way from the standard O16 to O19, and Hydrogen turns into Tritium eventually, which is fairly harmless.
2. Don't bother making a shaft, just let the icemelt refreeze over the top of you. Just leave a communications package on the surface (bury the sensitive bits under a few meters of ice to protect from radiation) and dangle a wire to an aquatic comms package that's anchored to the bottom of the ice.

The only practical way to put a sunshade between Venus and the Sun would be to use a swarm of reflective satellites at the Sun-Venus L1 point, so yes. Rather than a single monolithic shade, which would be ripped apart by tidal forces, you'd use a swarm/cloud of objects kilometers wide, and with significant overlap between each other's edges.
Also, you wouldn't keep this swarm precisely at the L1 point, you'd actually keep it slightly closer to the Sun, and use photon radiation pressure to keep the mirrors in place over time.

At the lagrange point, gravity is balanced. Move closer to the Sun, and gravity pulling you towards the Sun begins to get stronger. Since your reflective satellites are acting like solar sails, all you need to do is place them far enough towards the Sun relative to the L1 point that the pull towards the Sun is counterbalanced by photon pressure that's trying to push the satellites away from the Sun.

This would also be unstable in the case of a single sunshade, but with a swarm you can set it up so that the shades are all in a halo orbit just behind the actual balance point, such that passing behind the swarm and into the dark causes the shades to accelerate towards the Sun, and coming back out into the light causes the shades to accelerate back towards Venus. This arrangement should be stable enough to only require small amounts of active management, which would probably be done using heavy laser arrays to apply little pushes to the sunshades now and then.

Actually these would be lagites, not statites. A statite can hover stationary above the Sun due to photon pressure alone, a lagite can remain in a circular orbit at a lower velocity than a normal object at that distance due to a counterbalance of photon pressure. Technically, any object in orbit of a luminous body is a lagite, since all objects absorb and/or reflect light, which will transfer momentum.

10% larger but higher density, think about how Mercury is ~1900 km less wide than Mars, but they both have the same surface gravity because of Mercury having a higher density. A planet 10% wider than Earth with 150% the density would have a surface gravity way higher than Earth, easily. 2g is probably an underestimate.

Neat fact, convection in the core of Earth is not driven by heat, it's driven by the precipitation of iron from molten iron sulfide at the inner core to outer core boundary. This precipitation causes lower density sulfur to build up next to the inner core, which rises up in plumes to drive convection currents. This precipitation also releases a bit of heat, which combined with radionuclide decay keeps the core hot enough to easily convect.
The mantle is where we see thermal convection taking place, over much longer time scales. The mantle itself is also stratified into density layers based on water content, but this stratification is not completely uniform or permanent, and local upwellings of lower mantle material or downwellings of upper mantle material or even sunken oceanic crust can and do have noticeable effects on the crust, and therefore on what we see at the surface.

A teaspoon of neutron star matter in earth gravity would weigh as much as a mountain. On a neutron star, a teaspoon of neutron star matter weighs far more, in fact a trillion times more. Remember, weight force is a product of mass and gravitational acceleration. The mass stays the same in both cases, but the gravitational acceleration goes up by ~10^12 times.

A neutron star is about three times the size of its own Schwarzschild radius. Earth has a schwartzchild radius of about 1cm. Therefore a sphere of neutron star matter ~6cm across (3cm in radius) should be roughly equivalent to the Earth in mass, IF you naively assumed that a black hole's density to mass ratio is linear (ie twice the mass, twice the volume). This is not the case, which is good, because otherwise with that density a typical neutron star with a 20 km diameter would have a mass of 2.96 x 10^17 Earths, and would out-mass all the non-dark-matter mass in the galaxy. Obviously this can't be true, which is where the fact that the density of a black hole's event horizon volume is inversely proportional to its mass comes into play.

Doing the math a different way, Earth has a total mass of about 6x10^24 kg, and neutron star matter has a density of ~10^17 kg/m^3. Therefore, you'd need 60 million cubic meters of neutron star to have an Earth's mass of material, which is a sphere ~486 meters across. This makes a lot more sense, because if you mashed ~333,000 of these Earth-mass spheres together, equivalent to the mass of the Sun, you'd have a sphere with a radius of ~17 km, which lines up pretty well with a lower mass neutron star (they shrink as they get more massive, crushing themselves more under their own gravity).

You're not wrong, but they want as much data as they can. If it flies up to 15k and gets slapped around so badly it just tumbles into the ocean, they won't get any decent "belly flop" reentry data.
However, if flight is successful and it can test out its flaps in a controlled manner on the way down, that's great data to apply towards SN9.
Greater strides in success and improvement.

Even if the material science allows for them on Earth, would space elevators ever be a thing?

You would need a massive low cost launch and orbital construction infrastructure just to build it, which would easily obsolete the elevator itself on the way there.

>> No.12420829

probably not. I think the only real place a space elevator would work would be pluto/charon, since you can anchor both ends.

Yeah. Starship would actually be cheaper than a space elevator if it hit its design goals anyway, that's not going to happen but neither would the first sky elevator reach theoretical best case numbers either. Down the line, larger more mature fully reusable rockets will be even better.
