If Starship actually works, the USA will have such an advantage in space technology. One that other countries can't hope to match for decades.
This has both military and commercial benefits that no other country can touch.

JAXA isn’t going to have a reusable rocket until the 2040s. ESA posted a diagram of their future rockets and they won’t have anything that resembles starship until the 2040s (someone post it I don’t have it saved) China won’t have a starship clone until as early as 2035

Imagine what starship will be doing then?

How can beam propulsion work but you cant carry a giant laser and point it backwards
>>
>>14734874
Giant laser pointed backwards does produce thrust. It produces half as much thrust as bouncing a powerful laser beam off of a mirror. Since a mirror is much lighter than a superpowerful laser and its energy supply, it makes more sense to carry a mirror and subscribe to a laser.

Instead of building the first mars base, any way one of the first starships can be built as the first mars base so when it lands there is a process to convert it into a base?

Would there be any way to controllably get it from a vertical to horizontal position once on Mars?
Or that is also too risky without much upside.


Do the computers that control starships bellyflop to vertical landing manuvers going to simulation train on Mars atmosphere levels, and is there other ways?

Like how different will the rates of fall and thruster power and angles be different in mars atmosphere?

Or the thrusters just do whatever they must do so that they recieve readings that the ship is perfectly vertical?

Once in place, the satellites have limited ability to maneuver. You toss up a bunch of debris into the plane you want to go dark. You can't just target one area on Earth, but you can target any plane that covers that area. More satellites would have to be launched to replace those lost and if the plane is littered with debris, you have to wait a couple of years for it to clear.
Early on Musk said SpaceX wouldn't get involved in politics because it would be dangerous to the the survival of the Starlink constellation to do so but he quickly went full retard with Ukraine, angering one of the nations that can very easily destroy Starlink if it wants. Getting Starlink and SpaceX involved with Taiwan and China would be even stupider. Don't be surprised if at some point China has an "oopsie" that knocks out Starlink should SpaceX continue to operate as an arm of the US government.

>More satellites would have to be launched to replace those lost and if the plane is littered with debris, you have to wait a couple of years for it to clear.

Once Starship is operational, it'll be fairly simple to replace damaged sats & clear debris with other specialised sats, the payload capacity will be totally unprecedented.

>angering one of the nations that can very easily destroy Starlink if it wants.
>Don't be surprised if at some point China has an "oopsie" that knocks out Starlink should SpaceX continue to operate as an arm of the US government.

And the US military can even more easily destroy Beidou and GLONASS - and again, the US will replace lost sats even more easily than Russia or China can (IIRC Russia can't even afford to replace GLONASS sats which decay out of orbit on schedule).

If I were China I wouldn't do shit in space until:
- Starship Clone
- WWIII

whichever comes first

and if I were Russia, I'd just swallow my pride already and buy Chinese

Given the number of satellites spread out across so many orbital planes it's simply not viable to take out Starlink with a shotgun approach. China simply can't lift enough mass to get the job done.

That's not to say that China couldn't do it; they just couldn't do it with shrapnel. A Starfish Prime sized nuclear test at the right altitude would get the job done. If you fill LEO with enough radiation you'd take out everyone's orbital infrastructure, at the cost of making everyone with satellites extremely angry and violating the Outer Space Treaty, which China is a signatory to. If you really want to take out a constellation like Starlink you need something like a high powered laser that could plink each satellite as they come over Chinese territory. The cost of firing a laser would be less than the cost of launching a Starlink satellite even with Starship, so you're winning the classical asat economic contest, and it's precise enough that you won't make an enemy out of every other nation with satellites.

>>14735169
The problem is that the Russians tried buying Chinese back in 2015 and the shit the Chinese were selling turned out to be even worse shit than the Russians were expecting it to be.

If I'm trying to land on Io, does it sense to enter Jupiter orbit first, or try and direct approach Io? Would it be smarter to enter a high jupiter orbit, or an orbit close to Io's orbit and then enter? Does it make any difference in terms of fuel spent?
Basically I'm asking, what's the most fuel efficient way to enter Io orbit, without use of gravity assist maneuvers? (I'm not opposed to gravity assist just I want to also have the most expedient trip possible)

It depends on the thrust to mass ratio of your spacecraft. If you can just capture at Io it's fine, provided you're moving in a favorable direction relative to Io. If you can't physically complete the entire burn at Io you should capture into Jupiter orbit first. Also, using gravity assists from a captured elliptical Jovian orbit is feasible, and could save a lot of delta V in exchange for much more time needed.

>Compact Composite Objects (CCOs), nuggets of dense Color-Flavor-Locked Superconducting quark matter created before or during the Quantum ChromoDynamics phase transition in the early universe[1, 2, 3], could provide a natural expla-nation for both dark matter and the observed cosmological baryon asymmetry[4, 5, 6], without requiring modifications to fundamental physics. This hypothesis predicts a relic CCO population in the solar system, captured during its formation, and thus both massive strange matter cores in the centers of the Sun and planets, as well as a present-day population of "strange asteroids," bodies with mm-radii quark matter cores and ordinary matter (rock or ice) mantles. Methods based on neutrino radiography and solid-body mechanics are developed to detect such strange matter cores in solar system bodies. The CCO hypothesis is directly supported by the observed population of small Very Fast Rotating (VFR) asteroids (bodies with rotation periods as short as 25 sec); the VFR data are consistent with the existence of strange asteroids with core masses of order 10 10 -10 11 kg. If the VFR asteroids are indeed strange asteroids their CCO cores could be mined using the techniques being developed for asteroid mining. Through a process analogous to Andreev reflection in superconductors[7], even normal matter CCOs could be used as antimatter factories, potentially potentially producing as much as 10 9 kg of antimatter per CCO. While of course speculative, this energy source, if realized, would be suitable for propelling starships to a substantial fraction of the speed of light, and could be found, extracted and exploited in our solar system with existing and near-term developments in technology.

It's a lot heavier because solid propulsion is about 75-100s less efficient than the liquid engines Electron uses.

One of the big reasons it's cheap is cost-sharing with the Indian ICBM program. It's easy to get a cheap launcher when the same production lines are rolling out bulk orders of missiles to aim at China.

PRUFROCK fits in a starship with room to spare.

>It should fit in Starship which is where I’m guessing you are going. SpaceX site doesn’t list it but based on a couple of visual clues it will fit in a Starship and be roughly 1/3 the total weight. The tunnel dimensions it can dig are ~12 feet in diameter and on SpaceX site it’s shown in a graphic being transported on a flatbed truck so it’s max length is about 50 feet long. That is about 60% of the projected space in Starship cargo bay. On the weight part… A truck and trailer typical max weight is 80k lbs and some states allow a max tonnage with 3 axels on both the trailer and a drop axel on the truck to hit 100k lbs. truck and trailer weight is ~35k lbs so that means PRUFROCK has to be between 45-65k lbs or 22.5-32.3 US tons which is about 30% of the Starship projected tonnage capacity.

yeah they really need to have more options for procedural parts with heat shielding. you've got wings and tanks and that's it i think. if you want to make it feel less cheaty you could edit the fairing to weigh more too.
meanwhile my flyback booster experiment has me convinced this was always a horrible idea for gameplay reasons alone. it's going to take like 45 minutes to get back to the cape and i'm too scared to touch timewarp.
on the other hand i'm kinda seeing the logic for real-world. reversing your course in space takes like 4 km/s of delta v and with a true flyback you can kill your velocity in the atmosphere and then the jet engines' ISP is so high that you can almost make it back on propellant residuals alone.

Which doesn't make sense because if they lost telemetry they shouldn't be able to tell if the fourth stage performed nominally and according to the flight events log the liquid engines shut down less than a second in. They could be about 500 m/s dV short of desired orbit.

its not cheaper than regular falcon launches, that's why
raw upmass isn't the important factor, cost per kilo is, and falcon heavy's increased ability is entirely offset, if not put into the negatives, by heavy's increased cost
Starship on the other hand will drive costs into the floor to the level that it would be worthwhile to totally overhaul satellite building methods to capitalize on it, though it'll undoubtedly require a lot of boomers retire or die before it can happen

At least initially, Starship will be more expensive than Falcon Heavy.

>The first demonstration flight of SSLV was not alone, on top, the fairing was carrying the aspirations, hopes and hard work of 750 girl students from across India, who had toiled and built AzadiSAT, a nine-kilogram CubeSat that has a mission life of six months.

You're the one trying to confine the discussion just to Astra Rocket 3.3 because you have zero evidence in support of a 4 million dollar price for SSLV, after it was pointed out that the rocket itself is complete and utter trash by any performance metric.

that's nothing new or special
almost all launch vehicles started as ICBMs and launching probes and people on top of it was an afterthought (Atlas, Titan, R-7, Proton)

Yes, as a quick way to show that you're full of shit because Rocket 3 was priced cheaper than SSLV and so will Rocket 4 and dozens of other small-lift rockets from new space companies. This part of the industry doesn't have a future but that's to my point and SSLV will have few customers.

I wish Astra wasn't so retarded, because I actually find their thought process interesting. It doesn't matter how bad your cost per kg is as long as you have the smallest cost per launch. And then you can shit out rockets like sausages and drive down cost purely by mass production. Instead of launching like 500 Starlinks on a single Starship for $20 million, you can launch one on an individual rocket directly to its trajectory for only $5000.

At the peak of Astra hype, I liked them merely for trying something other than reusability to get price down, but then it became apparent that the financial case wasn't there and that their QC was shit and the dream came crashing down.

It's an indicator of low combustion chamber pressure I think, I could be wrong. Basically yes though, longer chamber for longer gas residence time to allow increased combustion efficiency. Both RS-25 and Raptor have very short combustion chambers because they have very high pressure chambers with good mixing efficiency and therefore don't need much residence time to achieve high combustion efficiency (by combustion efficiency I'm only referencing getting all of the oxidizer reacted with the fuel, the mixture will still be fuel rich but ensuring there are no O2 molecules exiting the nozzle is important for maximizing efficiency).
>>
>>14737091
I though there could be a opposite effect taking place, higher pressure engine have their gases leave faster which gives them less time to burn
>>
>>14736912
I'm fairly sure the apparent demand reduction is an artifact of SpaceX accelerating their launch timeline and eating up backlog. They're at a point now where commercial flight schedule movement is completely dominated by payload readiness, not by launch vehicle readiness. For example, the Falcon Heavy launch delays this year are because the payloads it's meant to throw up there aren't ready yet. Many such cases.

>>14736930
Payloads weren't/aren't ready. FH is good to go whenever.
>>14736967
More or less agreed, however as cost is reduced the commercial space ambitions should increase (we already see this with commercial Moon and Mars robotic missions), and as the commercial sector starts doing things on par with or even exceeding what government missions are doing, the government ambition should also increase (in such a way that total volume of money being spent doesn't change much but procurement pivots to the more economic options).
There's also a chance that government exploration programs cede ground to commercial activity and push farther out as a result. Maybe with much more commercial activity around the Moon and Mars and Asteroids, the government programs shift focus to things only they can currently do effectively, like high power to mass ratio nuclear energy solutions in space, and ultra deep space missions. I would expect that in a world where Starship is doing Moon and Mars landings and spawning a commercial ecosystem of extraterrestrial surface resource exploration, the government would take advantage of Starship to launch some very large, advanced probe spacecraft to go orbit the gas giants and ice giants and Kuiper belt objects, things on the scale of the Leviathan Venus probe concept and perhaps even bigger depending on where they're going and what they're doing.

Maybe, but then that implies some level of turbopump inefficiency compared to the RL-10, unless this engine produces significantly more thrust.
Jumping off this topic, I really want to see someone try to build a 100 kN staged combustion hydrolox engine. Why do I want this? To put to bed the idea that the expander cycle engine is the most efficient engine cycle. It's not. It's decent, it's about as thermodynamically efficient as a staged combustion engine, except it's got such a low chamber pressure that it misses out on some significant Isp gains. A similar mass, similar thrust staged combustion engine would have a waaay higher chamber pressure and could be as much as 5% more efficient than an equivalent expander cycle.
By the way, the reason the RL-10 has the record for the highest Isp engine to ever fly (465.5 Isp) is because the vacuum optimized version has a really big nozzle ratio (280:1). For reference, the RS-25 had a weird shaped nozzle with a ratio of just 78:1 but produced 452.3 Isp. At a nozzle ratio of 280:1 and a true bell shape suitable for vacuum optimization, the RS-25 would have easily blown past 470 Isp, so imagine what a raptor-architecture-based FFSC hydrolox engine could achieve.

>Starship will be A architecture with C process

Sending components as neatly packed pieces to be assembled into a larger, habitable structure would allow for greater projects.

>>
>>14737186
Process is how well polished the stated architecture is. Architecture is how capable the design is.

Falcon 9 is B architecture because its only partially reusable, but has an A process because its a lean machine now. 5 years ago, it would be a C process when they're learning the curves. 2-3 years ago, it would be a B process when there were still some small hickups.

Okay, so why does Starship get a "will be C" for process? It's a C now, sure, since everything from the vehicle to the GSE is prototypes interfacing with prototypes, but I expect Starship to reach A process status in roughly as many launches as it took Falcon 9, which will occur much faster in real time compared to Falcon 9 due to full reusability eliminating the fabrication time of new stages from the equation.

Also process is dependent on architecture. So 20 launches per year Starship isn't same process as 20 launches on falcon 9. The difficulty curve is higher for higher architecture. To get to B process on Starship, it would have to do ~20 flights a year, but that's A level process for F9. A level process for Starship is 40+ launches a year

There's a big difference between an extendable nozzle curve being used to allow for altitude compensation and an extendable nozzle that only deploys in space and exists purely to improve packing efficiency for the second stage engine (what the RL-10 does these days). The difference in the curve impacts Isp significantly. For example, if that RL-10 with the extendable nozzle fired at sea level with nizzle extension stowed away, it would produce trash Isp, due to having a horrible nozzle shape. Think RS-68 on the test stand with no ablative bit. For a vehicle trying to launch under its own power then extend nozzles later, this Isp hit at sea level is unacceptable, so the nozzle shape needs to be adjusted and tightened up in order to keep the Isp and TWR good enough for launch. However, this means that no matter what the nozzle extension looks like, it will never achieve the Isp of a vacuum optimized curve of the same expansion ratio once in space, because the upper section of the nozzle can't have the "perfect" shape due to that sea level performance requirement. Basically it all comes back to "split optimization between sea level and vacuum Isp sucks mega shit dicks".

>that implies some level of turbopump inefficiency compared to the RL-10, unless this engine produces significantly more thrust
from the photos is looks like Vinci (it sure as hell isn't Vulcain)
it supposed to have almost the same ISP as RL-10 (give or take), at the same weigh, but ~50% more thrust and lower cost because it doesn't use the autistically artisinal tubular bell (Aerojet Rocketdyne must be Mike Oldfield fans)
so you get the same performance as 2 RL-10s for the price and mass of 1

It's because of the way it is. Expander cycle is effectively the fuel rich staged combustion cycle except running with a MUCH colder working fluid (boiled hydrogen versus 90% hydrogen 10% water vapor belching out of a preburner).
The expander cycle engine's relative power output is fundamentally determined by the ratio of heat conducting into the walls of the engine from the hot gas in the main combustion chamber to the propellant mass flow rate. More heat per kg of propellant equals more turbopump power. More turbopump power means higher propellant pressure. The square cube law means that smaller expander cycle engines have higher performance upper limits because there's literally more nozzle wall area per kilogram of propellant flowing through the engine. The main drawback is that the heat powering the engine is conducting through the solid nozzle wall components, which means that you are limited in engine power by your materials, whereas in a staged combustion cycle you are burning propellants to make heat inside your working fluid, so the temperatures you can achieve are much higher. Also, in a staged combustion engine you can have a dense liquid propellant mixture burn to produce a dense hot gas which can immediately expand across a turbine to do work on a pump, whereas in an expander cycle your working fluid must boil at high pressure in the nozzle walls then flow through channels and pipes to reach the turbopump, resulting in a large pressure drop before reaching the area where it can do useful work in the engine.
To summarize, a staged combustion engine cycle allows for much greater power to mass ratio, higher chamber pressures, higher Isp, and generally better performance (it also throttles faster, though not as deeply). The main drawback of staged combustion is the requirement for advanced materials, but now that we have those materials the challenges are mitigated for the most part. Raptor proves they can be cheap, too.

How many different kinds of electric and magnetic experiments have been done outside the iss in 0 g free 'vacuum' space?

I understand the difficulty and danger and fear of such experiments possibly messing up machines and equipment or suit.

I'm curious as to how 2 or more very strong permenant magnets act on one another at decreasing distance; and if such field qualities in-between them can be detected or measured.

I think the problems will arise from the fact that you're putting radioactive CO2 inside of the suit, which will almost definitely lead to it being absorbed through your pores.

You joke, but if anti-ship balistic missiles become a new paradigm for naval warfare, then I could see the utility in having a re-usable HGV thrower, a VTVL rocket can theoretically land in a much smaller space than an aircraft.

>Calculation of ballistic flight path options for a manned expedition to Mars
Fast transfer is the only option. You wait for the launch window to almost close, then you burn with the hohmann transfer delta V plus 1.5 km/s, then you aerobrake on arrival.
If you cannot aerobrake or you cannot provide the extra 1.5 km/s above Hohmann transfer delta V, your architecture is incorrect.

It means you're in freefall but close enough to a source of gravity (ie a planet) that tidal forces are inherent to the environment. Effectively, the gradient in gravitational strength between one side of your experiment and the other is equal to about 1 one millionth of Earth's gravity.
Ultra low tidal force environments, like the Earth-Moon L1 point, can get down to picogravity conditions, and super deep space environments like the scattered disk far from any other objects and hiding behind a sunshield can achieve even lower "gravities".
>>
>>14737743
Nope, it's referring to tidal strength, which results from gravity being stronger at your feet than at your head. It's a squeeze and stretch, not a "real" acceleration towards anything.

the (pseudo)forces due to the rotation of the ISS far exceed any tidal forces. I think using the term microgravity for the ISS environment is a misnomer
