Thoughts on panspermia, /sfg/?

https://en.wikipedia.org/wiki/Panspermia

> Panspermia (from Ancient Greek πᾶν (pan) 'all', and σπέρμα (sperma) 'seed') is the hypothesis, first proposed in the 5th century BCE by the Greek philosopher Anaxagoras, that life exists throughout the Universe. It is thought to be distributed by space dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms. Panspermia is a fringe theory with little support amongst mainstream scientists. Critics argue that it does not answer the question of the origin of life but merely places it on another celestial body. It is also criticized because it cannot be tested experimentally.

> Panspermia proposes (for example) that microscopic lifeforms which can survive the effects of space (such as extremophiles) can become trapped in debris ejected into space after collisions between planets and small Solar System bodies that harbor life. Panspermia studies concentrate not on how life began, but on methods that may distribute it in the Universe.

> Pseudo-panspermia (sometimes called soft panspermia or molecular panspermia) is the well-attested hypothesis that many of the pre-biotic organic building-blocks of life originated in space, became incorporated in the solar nebula from which planets condensed, and were further—and continuously—distributed to planetary surfaces where life then emerged.

The theory that stuff like proteins could have formed at around the same time as planets, and ultimately evolved into early lifeforms when planetary conditions were suitable, is perfectly reasonable. Amino acids were found on a comet, despite there being a very low sample size, which suggests that organic compounds are relatively common in space.

Anything beyond that enters schizo territory.

>This second-generation NHT features three discharge channels and has seven distinct operating regimes comprised of the various combinations of channel operation, discharge voltage and current. These configurations allow for an unprecedented range of operation from low-voltage, high thrust-to-power, to high-voltage high-Isp operation, with a power throttling range spanning 1 kW to 200 kW. The thruster should be able to achieve up to 15 N of thrust at moderate specific impulse and 4,600 sec of Isp at high voltage with xenon and krypton propellants, respectively.

You could probably do it in a few months with OKEANOS style power sails. A quick and dirty example since I'm too lazy and retarded for anything else, using the largest nested hall thruster posted above

Thrust: 126 N(taking the average since I don't know the mN/kW at the assumed Isp)
Isp: 4,600 seconds
Power: 2.4 MW
Thruster mass: 320 kg
Solar panel mass: 2,400 kg(1000 W/kg at 1 AU)
Xenon propellant mass: 10,932 kg
Tanks, PPU, structure mass, etc: Let's say 5,000 kg

Payload: 11,348 kg
Delta-V: 20 km/s
Acceleration 0.0072 m/s squared

So if I'm not mistaken, the burn would last only 55 days.

Utter nonsense and you don't know what you're talking about. The ISS doesn't need to accelerate beyond reboosts and it was a retrofit with high structure mass prioritizing efficiency and longevity over specific power. There have been demonstrated non flexible blanket pv ~500 W/kg panels going back decades and just see any modern discussion on the subject, JAXA's OKEANOS, Caltech's SSPP, etc. Caltech is demonstrating their >1000 W/kg technology as we speak, IIRC 50 g/m2 for the structure and 100 g/m2 for the panels.

Caltech researchers are claiming 160 grams per square meter for each generating cell, with an end to end efficiency between 7 and 14%. Factoring in solar irradiance and being optimistic about the generating power, a kilowatt of solar cells, without structure, should weigh ~847 grams. https://arxiv.org/abs/2206.08373

A technology demonstrator does not a manufacturing line make, and the scalability of the techniques as a production process are important considerations. I'd assume the pessimistic number for end to end efficiency and, optimistically, merely double the mass for a representative production model for 3.388 kilograms per kilowatt, plus structures.

Earth's solar constant is 1361 W/kg, even 7% efficiency would be ~600 W/Kg, thus 14% would be ~1200 W/Kg, the Caltech numbers include the structure and the specific power increases with scale, not decreases as you previously asserted last time you brought up this stupid argument.
>Inverse square law

>A technology demonstrator does not a manufacturing line make, and the scalability of the techniques as a production process are important considerations.
Important considerations that have nothing to do with you greatly intentionally underestimating the specific power for reasons that are beyond me. These are highly reputable organizations stating these numbers of realistic, greater evidence than your random cherry picked assumptions that aren't worth addressing.

So how long are we going to go back and forth for? The examples just go on and on, Redwire produced the ROSAs you mentioned and they said in 2012, back when thin-film efficiency was much lower, that they could do ~500 W/kg at wing level. Are they lying, are you going to call the SEC?

The last N1 kinda worked for most of the S1 burn, it didn’t have engine failures until the whole thing failed Kek, and improved nk-33 were on the way for future launches, so they probably would have gotten one right, the question is could they have the reliability to risk humans or expensive payloads on top of it? That’s much less certain

The advantage of the N1 was that it had dual launches capability (two pads) and had a decent production rate (it peaked at roughly at 4 a year In 1972 before being scaled back, and there was room for improvement, 3 dual launches may have eventually been possible), so they probably would have more launchers than payloads, but risking a huge Skylab style station on each launch isn’t possible, so it would have to either launch payloads that are also produced in series or at least with a spare or launch cheap, heavy payloads. It also wouldn’t work well with the planned expensive hydrogen upper stages

I think a N1 based soviet program could end up mostly launching huge and cheap kick stages for Proton/Soyuz launched payloads

Kuznetsov could make at least 150 nk-33 engines a year by the time their production was stopped, with room for improvement, that’s almost 2022 raptor level
Considering how quickly they were updated and improved to be restartable and reusable and deep throttlable in the 90s there’s a lot of missed potential

There was some proposal to use them in Zenit when the RD-170 was destroying test stands in the early 80s (it was only an open secret that there was still some stockpile of them)

> This Paper reports 100 times scaling up of PLT using a ytterbium-doped yttrium aluminum garnet (Yb:YAG) thin-disk gain medium and thought first demonstration of propelling and stopping a 0.75 kg mock cube satellite over 2 m in a Class-1000 cleanroom. A thrust stand for PLT was established with a radiation pressure sensor that reduced the thermal convection effect and the configuration complexity. The maximum achieved thrust and specific thrust were 3.36±0.18mN
and 7.1±0.6mN/kW
, respectively. Further development of PLT using existing high-power laser technologies is projected to increase its specific thrust to 68±10mN/kW
, on a par with electric thrusters. The present results conclude that innovative PLT applications, such as propellant-free orbit maneuvering and stationkeeping, are within the reach of existing spacecraft and high-power laser technologies. In addition, the feasibility of PLT-based launchers and landers is discussed

IF literally anyone else hasn't landed a rocket even once by 2030, the industry at large will be completely fucked. If SpaceX manages to put <100-500 people on Mars by 2030, they'll start announcing plans of a 12 meter Starship, and the rest of the world will become increasingly invalidated by a private company. Though I suspect that once Starship reaches Falcon 9 cadence, the rest of the world will be fucked anyway. It becomes nearly impossible to compete with a SLS class vehicle that costs as much as a Falcon 9 to launch and can be launched 1-200 times a year easily.

It's not worth it, NTRs already have a dry mass problem because LH2 is much, much, less dense than LoX or CH 4, but say you beef up your weak ass tanks and inflatable habitation module to withstand the forces involved in aerobraking, you still need an inflatable heatshield and it much be large enough in diameter to cover the long 'stick' shaped assembly.

So why not have the NTR drop off a mini-Starship like vehicle which then does direct entry? Because then you need a much larger NTR to get the lander and hundreds of tons of propellent on Mars intercept and you'd still need to get a vehicle like that stationed on the planet if you just dropped off a capsule and aeroshell.

The solution to all of this is to just fucking use Starship, god damn.

No it doesn't, their last test in 2021 was only 88 hours, they only need 100 hours to advance to the next TRL or something like that and get more funding from NASA but they're still nowhere close to a useable engine. Clearly they've run into major technical issues.
> I wish /sfg/ would shill something that actually had high thrust to weight
You can wish for whatever you like, high thrust is vastly overrated outside of gravity wells and delta-v is is the determining factor for interplanetary transfer time, nearly all of the forms of advanced but realistic propulsion would still take years to reach any distant planet.

Why even complain? No one is stopping you from posting about whatever you want but that would require effort and for you have an actual solution, which you don't have.

No, it actually has pretty good thrust to power compared to the butterfly farts of ion thrusters. That paper has a good figure where they had a few runs over 0.1N/W, and IVO (who's making the thrusters for the test payload) gets about 10% of that last I heard. It makes sense intuitively, there's no need to pump propellant around or heat and ionize a cold neutral gas like other electric thrusters, so more of the energy translates to thrust.

>As Dana Andrews remembered it, Boeing’s engineers first proposed using the Space Shuttle Main Engine “as a major performance improvement” to the craft. The SSME has over 2.18 million newtons (490,000 pounds) of thrust in vacuum. It’s a powerful thoroughbred of an engine.
>But Pratt & Whitney’s engineers countered that the SSME was not ideal for the job. Instead, they opted in favor of a cluster of seven RL10s at the rear of the fuselage. They would be identical to the ones used in the Sortie Vehicle but would have different nozzles. The RL10 required less than a minute of preconditioning prior to start, compared to approximately 40 minutes for the SSME. The RL10 cluster provided engine-out capability, reduced initial and operating costs, and “ripple start capability” that reduced the tank pressure requirements for starting compared to the SSME. Pratt & Whitney even posed the possibility of using the RL10s during aircraft takeoff to get off the ground, just like the “Jet-Assisted Take-Off,” or “JATO” rockets used to launch heavy aircraft in the 1940s and 1950s.
>The aft end of the fuselage proved to be a good location for the rocket engines. The rear of the 747’s passenger cabin contains the end of the pressurized compartment of the plane. The pressure in the tank pushes against the back of the tank, and the rocket engines could be mounted on the other side of the tank and would push forward against the air pressure inside the tank pushing back. It was a structurally sound design.

Hendrickx’s Energia book says that Zenit-2 could do 7 tons to LEO if the Energia recovery system was put into it (and the Sep speed is lowered) and I ran the numbers and it does roughly check out.

However you can stretch the second stage (the RD-120 has some room for improvement) to take advantage of the lower Sep speed and reach 8 tons to LEO maybe 9 with the later Zenit-3 improvements.

Not too bad; worse than F9 ASDS in term of payload penalty but better or at least not worse than F9 RTLS.

Interstellar travel is perfectly feasible as long as you have some propulsion device that can supply constant thrust for like months-years on end
So assuming some sort of reactionless drive is discovered one day, all you’d need is a ton of them on your ship and some big nuclear reactor for power. If you’re getting anywhere near 0.5 to 1g of constant thrust you can visit pretty much any star system in the milky way in one lifetime

2.9B/41B = 7%

SLS/Orion/MLS will require ~2B per year in funding + $4B per launch, which equals to ~$10B for "R/D" and ~$11B for the vehicles. So thats another 51% of the budget. HLS total is ~$11B - $2.5B (assuming 400M has already been paid out over the last 2 years or so) for SpaceX = $8.5B for the second lander NASA wants to choose. Thats another 20%.

So 51% for SLS/Orion, 20% for 2nd lander, 7% for Starship = 78%

They're getting paid billions to perform lunar missions, that is different from companies like ULA who have received billions for development with no strings attached. The majority of Starship is self funded by SpaceX.

Yeah. It's horrible what they've done. Think of all the contractors who will suffer if they succeed with their horrifying plans to make spaceflight cheap.

You now remember the leaked ULA emails

[Anonymous No.15440713]

The fact that Lueders awarded the sole contract to SpaceX before taking this job after "retiring" from NASA needs to be investigated by the DOJ.

This seems to epitomize the corruption rampant in the industry right now.

99.9999% chance it doesn't work. Even if it miraculously does work, you're looking at decades of research and redefining physics around a system that breaks the old one. Only once it's understood could it start being applied in any serious sense. think fusion in the 90s (or in this case cold fusion lmao)

You praise through buying and using it. The money which goes back to the CCP. So does everyone else.

In fact, its worse than just praising, you're directly contributing to CCP. Whereas Musk just gives lip service to China and makes money off of THEM and back into his pockets and his worker's pocket, in the US.

Shit I’ll bend the knee to the CCP if they do cool shit like a venus or mars flyby or something. A landing is preferred, but I’d still suck the yellow dong for more money towards space exploration.

Actions speak louder than words.

China is all about face saving. Thats all. In the US, far left communist circles, you also have similar face saving in the form of virtue signaling. Whatever is said don't mean anything, in fact, it means the opposite most of the time. So if Musk is apologizing, it doesnt care. If you're saying, you care about China, you really dont. Virtue signaling nonsense has no place in real life.

What advantages do spaceplanes have over bellyflappers? The only one I can think of is having nuclear engines; with wings you could land on earth for servicing. Can’t really propulsively land with nuclear engines lol. But at the same time, nothing is stopping you from just servicing nuclear engines in orbit. Idk, the added mass of wings and landing gear seems dumb.

x-37b can do high inclination changes because it can use the atmosphere to maneuver when it lowers it's altitude enough. to do that with other spacecraft you'd need to be able to refuel.

[Anonymous No.15440811]

>>15440797
It has never done so, it would be limited to small inclination changes, and it would require propellant which it may not even have to get back to a working altitude. Almost like the X-37 is a complete fucking meme.

I work with E-prop thrusters. The reason you never see "multi ring" thrusters is because the cathode is the limiting factor. Thrust linearly scales with power and gas injection, but cathode life scales negatively so it kinda cancels out any of the benefits.
