https://spacenews.com/falcon-9-launches-cargo-dragon-to-space-station-with-new-solar-arrays/

> The CRS-28 mission is carrying about 3,300 kilograms of cargo to the station, and is scheduled to dock at about 5:50 a.m. Eastern June 6. Its biggest payload is a third pair of ISS Roll-Out Solar Arrays, or IROSA, that will augment the station’s ability to generate power. Those arrays will be installed during a pair of spacewalks currently scheduled for June 9 and 15.

> In addition to the solar arrays, the Dragon is delivering nearly 1,110 kilograms of crew supplies, 490 kilograms of vehicle hardware and 266 kilograms of science. That is far less science that past cargo Dragon missions: the CRS-27 mission in March carried about 975 kilograms of science investigations, compared to 745 kilograms of supplies and 440 kilograms of vehicle hardware.

> At a May 30 briefing about science on the mission, Kirt Costello, NASA ISS chief scientist, said that more supplies were flown on CRS-28 because of delays in the next Cygnus cargo mission, NG-19, by Northrop Grumman. “It’s also making up for the delays that we had in our NG Cygnus vehicle arriving at the station, so we’re sending up lots of extra logistics, crew supplies, for the crew to keep them going throughout the end of the year,” he said.

>>15483814
MUCH cheaper to make a short engine bell, considering the fancy metallurgy that goes into high temp alloys. on the scale of a falcon 9 launch it might only save a few percent cost-wise, but spacex is all about eliminating unnecessary expenditure. If the mission doesn't require absolutely 100% of the upper stage's delta-v then it makes more sense to use less engine bell, instead of using less fuel.

> EOSDA, Dragonfly and Space Electric Thruster Systems (SETS) are part of the Noosphere space group, established in 2015 by international entrepreneur Max Polyakov to create an integrated space business. Another Noosphere Ventures company, Flight Control Propulsion, oversaw 3D printing of components and the satellite structure for EOS Sat-1.

> EOSDA’s goal is to provide predictive modeling and recommendations to farmers.

> EOSDA also is preparing to feed data from EOS Sat-1 into EOSDA LandViewer, an online source for current and historical imagery that extends beyond the agriculture sector to serve markets like real estate and defense.

> SETS has developed two propulsion systems. Both feature Hall-effect thrusters, but SETS’ proprietary cathodes and power processing units have made the technology “a little bit more efficient,” Serbin said. “In the space industry, each percent of efficiency is important.”

> In the future SETS plans to sell off-the-shelf and bespoke propulsion systems “to become a part of the worldwide market for propulsion systems,” Servin said.

> If the mission does launch this fall, the spacecraft will reach asteroid Psyche in August 2029. There, it will go into orbit for 26 months to gain insights into planetary formation, understand the interior of terrestrial planets like Earth, and examine a world that is made largely of metal. The mission is also of interest to the nascent asteroid mining community, which seeks to learn about the potential value harbored by these relatively rare, metallic asteroids.

> Last year, Young and the rest of the board members found a litany of problems with the mission, including serious issues with the flight software and an incomplete process to verify that software and the vehicle's systems.

>In a report published last November, the review board laid much of the blame on management at NASA's Jet Propulsion Laboratory in California, which oversaw Psyche's development and testing. The field center, which leads many of the space agency's most prestigious science missions, had undertaken an "unprecedented workload" without possessing the resources needed to complete major projects.

> Laurie Leshin became the director of the Jet Propulsion Laboratory just weeks before the Psyche mission was put on hold last year. On Monday, she said she welcomed the independent review of Psyche's problems and the larger issues at the California-based field center so that they could be addressed by her leadership team.

> Since then, Leshin said, NASA has been aggressive about hiring from the tech industry—which has undergone significant layoffs—and recruiting back employees who were lost to private space companies in the Los Angeles area. In some ways, she said, NASA is the victim of its own success as it has sought to foster the US commercial space industry.

>>15484821
https://spacenews.com/nasa-psyche-mission-back-on-track-for-october-launch/

> NASA released June 5 a report by the independent review board (IRB) commissioned by the agency last year after Psyche missed two launch windows in 2022 because of delays in the development and testing of flight software. That board concluded last fall that Psyche had suffered from software development programs but also broader issues at the Jet Propulsion Laboratory, including a strained workforce and poor internal communications.

the report https://www.nasa.gov/sites/default/files/atoms/files/psyche_irb_assessment_report_with_nasa_response_may_2023_508.pdf

> “The IRB believes the response to our Psyche project and JPL institution findings and recommendations to be excellent,” Tom Young, chair of the IRB, said in a call with reporters. “We believe that Psyche is on a positive course for an October 2023 launch.”

> The delay does come at some additional cost to NASA, which officials on the call said is still being assessed. A May 31 report by the Government Accountability Office assessing major NASA projects noted that the cost of Psyche, projected at just under $1 billion at the time of its confirmation in 2019, has grown to nearly $1.13 billion as of January 2023. The report added that new estimate was under review because of potentially higher operations costs linked to a longer travel time caused by the delay.

> “The shuttle really scared the Soviets big-time because they couldn’t figure why you would need a vehicle like that, one that made no economic sense,” Siddiqi explains. “So they figured that there must be some unstated military rationale for the vehicle, for example, to deliver and recover large space-based weapons platforms, or to bomb Moscow.” The Soviets responded to the perceived threat by building their own space shuttle, Buran, which ended up being retired in 1993 after just one flight.

lol the shuttle was so retarded that it made soviets paranoid

> The idea of lasers shooting down at Soviet territory from orbit was truly terrifying. According to Westwick, the theories that floated through the Kremlin about the real purpose of the SDI got batty: “Selective political assassination. Say the Politburo is standing outside on May Day and a single laser could take them all out… These things are overhead, they’re invisible, but with zero warning they could zap you.”

>>15484844
Well they were sort of right, it was to steal Soviet satellites.

https://www.thespacereview.com/article/4595/1

> The losses to Japan caused by this failure are immeasurable. The satellite on the H3 was JAXA’s Advanced Land Observing Satellite-3 (ALOS-3). The ALOS-3 satellite was developed and manufactured at a total cost of about 28 billion yen (about $208 million). JAXA’s ALOS series has alternated between optical and synthetic aperture radar imaging satellites. ALOS-3 was the first advanced optical satellite for land observation since 2011, when the ALOS-1 satellite mission was completed. The ALOS-4 satellite, currently in the manufacturing and testing phase, is a synthetic aperture radar satellite. Therefore, JAXA is not expected to have an optical satellite for land observations until 2028 or later.

> [...] Therefore, until the H3 launch vehicle technology is proven, the GoJ should have planned to launch practical satellites for disaster risk reduction and security purposes on the more reliable H-2A launch vehicle. An alternative idea would be to use SpaceX’s Falcon 9, but that idea is unlikely to be adopted because the Basic Space Plan states that government satellites must be launched on Japan’s primary launch vehicles (either the H-IIA, the H3, or the Epsilon launch vehicle). This policy is to support Japan’s domestic space industries.

> Five launches of the H-IIA launch vehicles are scheduled in the future: three Information Gathering Satellites, the Global Observing SATellite for Greenhouse gases and Water cycle (GOSAT-GW), and the X-Ray Imaging and Spectroscopy Mission (XRISM) with the Smart Lander for Investigating Moon (SLIM). Given the reasons mentioned above for JAXA’s decision to launch the ALOS-3 satellite on the H3, it is clear that the more essential satellites were assigned to the H-2A; that is, the ALOS-3 satellite had less policy importance compared to intelligence gathering satellites, SLIM, and others

> Skif-D grew into a Frankenstein’s monster of a spacecraft: 40 meters (131 feet) long, more than 4 meters (13 feet) in diameter, and weighing 95 metric tons (210,000 pounds), more massive than NASA’s Skylab space station. The system consisted of what the Russians called a functional block and a payload module. The functional block—what Americans might refer to as a spacecraft bus—was equipped with small rocket engines to place the vehicle into its final orbit. It also included a power system using solar panels borrowed from the TKS spacecraft. The payload module carried carbon dioxide tanks and two 1.2-megawatt turbogenerators to produce the laser’s power, as well as the heavy rotating turret that pointed the beam. The spacecraft was built long and thin so that it could fit on the side of the Energia, attached to its central fuel tank.

> Designing a laser to work in orbit was a major engineering challenge. A handheld laser pointer is a relatively simple, static device, but a big gas-powered laser is like a roaring locomotive. Powerful turbogenerators “pump” the carbon dioxide to the point where its atoms become excited and emit light at a specific wavelength. Not only do the turbogenerators have large moving parts, the gas used in the formation of the laser beam gets very hot and has to be vented. Moving parts and exhaust gases pose problems for spacecraft—particularly one that has to be pointed very precisely—because they induce motion. The Skif engineers developed a system to minimize the force of the expelled gas by sending it through deflector vanes, which they referred to as “trousers.” But the vehicle still required a complex control system to damp out motions caused by the exhaust gases, the turbogenerator, and the moving laser turret. When firing, the entire spacecraft would point at the target, with the turret making fine adjustments.

speaking of space warfare

>>15484858

> Video screenshot of the Skif-DM spacecraft. The "functional block" is at front, serving as what American space engineers usually refer to as a spacecraft bus. It was adapted from existing space hardware and provided propulsion, power, and guidance in orbit. The lasers would be mounted in the long cylindrical payload module but were not included in the Skif-DM version. During the first and only launch, the functional block was supposed to flip the entire spacecraft 180 degrees so that it was pointed up and the engines were pointed down. However, a software error led to the spacecraft flipping end over end several times before pointing down, and its engines forced it into the atmosphere. (credit: buranarchive.space)

> On the night of May 15, 1987, Energia’s engines lit and the giant rocket climbed into the sky. Whereas most launches from Baikonur head for an orbit inclined 52 degrees to the equator, Skif traveled farther north, on a 65-degree inclination. If the worst happened, this heading would keep rocket stages or pieces of debris—or the Skif-DM itself—from falling on foreign territory. The goal was for a 64.6 degree, 280-kilometer orbit.

>After continuing its ascent, Skif-DM separated on cue and the spent Energia fell away. Then the entire 40-meter-long spacecraft began its gentle pitch maneuver. Its tail end—actually the front of the spacecraft—swung up through 90 degrees, through 180 degrees…then kept going. The massive spacecraft tumbled end over end for two full revolutions, then stopped with its nose pointing down toward Earth. In the rush to launch such a complicated spacecraft, the designers had missed a tiny software error. The engines fired, and Skif-DM headed back into the atmosphere it had just escaped, quickly overheating and breaking into burning pieces over the Pacific Ocean. The Soviet press agency TASS reported the loss of a “dummy satellite.”

>In the West, the debut of the Energia super-rocket was reported as a partial success, since the launcher itself operated perfectly; it was the satellite that had failed. The US government almost certainly had intelligence sensors pointed at the rocket as it flew, but what the CIA or other agencies concluded about the payload remains classified.

Schizo bullshit. There's hardly anything in the asteroids worth mining, and even if there was we'd use it all up in a few years supplying the needs of Earth.

>>15484876
> We still don’t know the entire story. “Even today there’s a lot of sensitivity about the whole program,” says Siddiqi, who has recently written a paper about how various parts of the Soviet government responded to SDI. “Russians don’t like to talk too much about it. And our understanding of Soviet responses to SDI still remains murky. It’s clear that there was a lot of internal debate within the Soviet military-industrial elite about the effectiveness of space weapons. And the fact that the Soviets came so close to actually launching a weapon platform suggests that the hardliners were in the driver’s seat. It’s scary to think what might have happened if Polyus had actually made it to orbit.”

> Another interesting thought experiment is to posit what might have happened had Reagan never announced the SDI, which had derailed arms control negotiations. Would the two leaders have gone further than they did if SDI had not become a point of contention?

wouldn't weaponizing space been a very large boon for space tech?

space mining for propellant and manufacturing *in space* makes sense and will be necessary
space mining to bring back materials *to earth* does not make sense in the near future and might never make sense
there are things like sending a probe to the asteroid field, it building a mining operation, refinery and a mass driver there and then this sent mass coming back to earth (and perhaps slowing down using the mass itself as propellant) might be possible at some point I guess but relies on a bunch of speculative tech nowhere near
and even then, it needs to compete with mining on earth itself

The problem is we don't have accurate surveys of shit. Are we looking at trying to prise out 0.000fuckall% percent of a rare metal from a homogenous m type asteroid or are there asteroids out there with relatively pure veins of whatever metal you need? Good thing we have no fucking idea thanks to half a century of gross corruption and incompetence!

Have you ever actually been on a sailboat? Your logic is pure wish fulfillment.

>critically limited space
You have infinite open space any time it's not raining or too cold. Just head abovedecks for direct sunlight and fresh air, or even go swimming if you're close to shore. Mars is more like a submarine.
>only limited tools at hand doesn't transfer
Correct, Mars will have hundreds of cubic meters of tools and supplies per person because it's safer than walking someone through Apollo 13 style kludging with multi minute light lag.
>navigation skills don't transfer
They actually don't. Land nav with topographical maps is completely different than orbital mechanics, and both are different from reading sea charts with tides and winds. Only the most basic level of symbolic reasoning is common to all three. Or did you forget that Mars doesn't have a working magnetic field so compasses won't work?

>>15484691

Wasn't it like 2 posters? The anonymous nature of this website let's individuals have outsized importance

>>15485058
it was not hysteria, that concept has a lot of potential
there is just not much point in discussing it over and over again until something new comes up
I'm hopeful after Starship starts launching regularly then the dude finds money for the project, I think the budget necessary was something like 50 mil, but not sure how much of this is for the satellite development itself and how much is for launch
you would need to launch it out of earths influence, so if you wanted to do a rideshare then there would need to be significant propulsion on the test probe
but there are a lot of companies starting to make satellite buses and different propulsion systems, so idk if that 50 mil is really accurate
cheap rideshare with starship + off the shelf bus and propulsion to get it away from earth
how much is it going to be to develop the actual payload?

> “It’s a myth that long-distance power transmission is impossible,” Electric Sky co-founder Jeff Greason said. “It’s just never been economical. This new method reduces the cost of the ground transmitter and the size of the vehicle’s onboard receiver.”

https://www.sbir.gov/node/2238077

> Whisper Beams use a new "non-gaussian" electromagnetic wave that focuses itself at the intended receiver, making it economic and practical to deliver kilowatts of power at kilometer distances. A UAV can carry a compact receiver to draw power while in flight. Swarms of UAVs can form a transmission array relaying power over several kilometers, such as from a main base to a forward base. With DARPA SBIR Phase I funding, we will build and demonstrate the first radio-frequency Whisper Beam transmitter at a lab-bench scale,powering a short-range UAV in flight. The technology readily scales to power large UAV swarms at kilometer altitudes, and/or wirelessly transfer power from a main base to a forward base several kilometers away. We will also analyze swarm patterns to optimize power levels over long distances.

march 2023
https://thedebrief.org/darpa-funded-electric-sky-on-threshold-of-aviation-revolution-with-whisper-beam/

> Seattle, Washington-based aviation technology company Electric Sky has announced a significant breakthrough involving its Whisper Beam power beaming technology.

seems like schizo stuff on the face of it, but I guess this guy likes to work on stuff that is speculative but still basically based on physics

>>15485086
I would really like his Q-drive idea to work. Purely electric propulsion would be amazing.

>>15485133
> In short, the technology involves using radio waves to send electric power to an aircraft that is equipped with a specialized receiving antenna, or “rectenna” as Millman called it, that can take that wireless radio wave and turn it into usable electricity. It is a surprisingly simple concept, but even Millman admits that taking something like power beaming from concept to execution with the goal of heralding a major paradigm shift in the way aircraft fly is no small task, regardless of how straightforward it may appear to be.

>“We started in earnest in the 2017 timeframe, and we knew we were taking on some rather ambitious things,” Millman told The Debrief. “Let’s just say that changing the nature of flight is no small thing.”

> “The major issues have been worked out,” Millman said. “The engineering issues, how to turn this into a practical application. Let’s say that there are many solved problems that have been solved over the last 4 or 5 decades, so it’s not like we are solving new stuff.”

https://www.freepatentsonline.com/y2020/0195057.html

> NON-GAUSSIAN BEAMS FOR LONG-DISTANCE WIRELESS POWER TRANSMISSION

> Systems and techniques are disclosed herein for generating and using Whisper Beams for wireless long-distance power transmission. For example, a radiofrequency (RF) Whisper Beam can focus high energy at great distances, which enables the technology disclosed herein to provide a practical means of transferring high power in a variety of applications and use cases. In some implementations, a method includes configuring an antenna to transmit two or more coherent out-of-phase Gaussian beams along a propagation axis to generate a beam of electromagnetic energy. The beam can be generated to propagate along the propagation axis, form a focus along the propagation axis, and has an intensity along the propagation axis that is less than a highest intensity of the beam off the propagation axis.

>>15485143
> As far as the distant future and where power beaming could ultimately go, Millman says they have modeled a system that can send power as high as 740 kilometers. This extreme altitude is well into low earth orbit, meaning their technology could not only power aircraft of the future but could also power spacecraft or space stations that operate in low earth orbit.

> One example used by Millman is the International Space Station (ISS), which typically hangs out at about 350 Km, an altitude that is well within the range of Whisper Beam simulations. As such, the ISS, Millman notes, would be an ideal long-term candidate since it currently employs massive solar arrays to generate around 100 kW of useable power.

>>15485143
Seems like you'd need a fuckhuge ground array to get the propagation to work like that.

>>15485152
I mean maybe, something they mention is using it for electric aircraft but just for ascent and descent, which are the most energy intensive portions of flight
and because electric aircraft don't need oxygen for combustion, they can fly much higher than conventional combustion engine aircraft
so you could put this thing on or near airports and then use it to get high up, cruise at high altitude with battery power, then descend over another airport using another array again
assuming it works of course

>>15485086
something interesting he mentions is that this won't probably get funded by NASA due to many reasons such as being experimental tech, but another one its a completely different method to do interplanetary missions (or missions up to jupiter or something)
now most of these people have one mission during their career, this thing would completely upend that model
and this is something he works on his spare time, not something he came up with but it seems so promising he has been trying to promote it

Why not spread life throught this galaxy in bacterial form? Cheaper smaller rockets and these life forms can manage millions of years inside a capsule surrounded by lead.

> Smith was less forthcoming about the schedule for the first launch of Blue Origin’s New Glenn orbital launch vehicle, which was once projected to fly in 2020.

>“If you want to know what the launch date is for New Glenn, I can give you one but it’s going to be wrong,” he said. “I don’t know if it’s going to arrive early or arrive late.”

> He said the company has flight hardware for the vehicle coming together, as well as preparations of its launch pad at Cape Canaveral. The vehicle’s BE-4 engines are one of the larger “pacing items” for the launch, he noted.

> Smith described Blue Origin as a company that shifted upon his arrival as CEO in 2017 from a research and development mindset to a more commercial focus with several lines of business. That includes New Shepard and New Glenn, as well as the BE-4 engines it produces both for New Glenn and United Launch Alliance’s Vulcan Centaur. The company also won a $3.4 billion NASA award May 19 to develop a second lunar lander for the Artemis lunar exploration campaign and is partnered with Sierra Space and other companies on the Orbital Reef commercial space station project.

> As for a timeline for profitability for Blue Origin, said, Smith, “it goes back to how much Jeff wants to invest.”

>>15484256
Go sideways

https://arstechnica.com/space/2023/06/china-and-europe-both-seek-to-emulate-nasas-success-with-commercial-cargo/

> On May 11, the European Space Agency announced a "Commercial Cargo Transportation Initiative" that would see one or more providers develop the capability to deliver 2 metric tons to the International Space Station by 2028 and be capable of safely returning 1 ton to Earth. Each proposing company must procure its own rocket for a demonstration mission.

>Less than a week later, on May 16, the China Manned Space Engineering Office announced a "Low-cost Cargo Transportation System" plan to hire private companies to deliver cargo to its Tiangong space station. Eligible providers must be capable of delivering at least 1.8 tons to low-Earth orbit. The Chinese spacecraft do not need to return cargo but should be able to dispose of 2 metric tons. The Chinese space agency said it would pay no more than $17.2 million per ton of cargo delivered.

> Foremost among those concerns is that both the European Space Agency and China's space agency seem to be skipping the "COTS" phase of the program, during which NASA shared its expertise and provided a substantial amount of money.

> But there is a serious downside, as well. While there may be more funding in the second round, the European Space Agency is counting on private companies to raise money, develop test articles, and procure a launch independently for a 2028 demonstration mission now. This will easily cost hundreds of millions of dollars—all for a chance to compete for future cargo supply contracts.

Yeah thats why I'm considering using keyed instead of based, but I dunno if that's cringe or not... its the only alternative I've heard of on here.

first time I've heard of keyed

>>15485276
Really? I know its a niche term even here but there has definetly been an infographic thrown around for it. Its been around for a while but nobody really uses it, maybe until now.

Does someone have that image? I think it looks like it was made in MS Paint. This is the best I could find.

Why is space such a scam?
I don't mean it in an /x/ schizo way
I'm just saying the entire thing is a fucking NFT/crypto tier ecosystem of pipe dreams and bullshit, to the extent that SpaceX over promises, under delivers, is always late, and is objectively the gold standard for success and progress

Like 90% of everything every government has ever done in space has been a failure or vaporware, and 99% of everything a private company has ever done.

I'm reading for the first time about how Heinlein's lawyer bought two partially complete Soviet space stations and had a big thing about "We'll have tourists exploring the asteroid belt by 2013" and it makes me think about Space Shuttle Fuel Tank Stations and Virgin Galactic and Venus Skylab and Space Station Freedom and Bigelow Airspace and Skylon and

https://www.youtube.com/watch?v=m1bNV0CUwPs

>>15485423
It's because of pic related plus the obscene costs of expendable hardware (and the space shuttle). Most of those proposals were technically possible but offered no economic return. We also had the misfortune of manned space development basically pausing for 40 years after Apollo so Moore's Law could crush payload masses down for most unmanned missions.

Bros, how do I go about writing Sci-fi. I spent too much time worldbuilding a future where a coalition led by Earth and another led by Mars are vying for control over the Jovian moon of Ganymede.

Ganymede has no central government and consists of disjointed groups of nomadic peoples. A glowie from the Earth-led coalition is sent to Ganymede to help the locals fend off an attempt by the Mars-coalition to take control it for use as “living space” (Ganymede has low radiation and would make for a great colony).

I also had another story idea set 100 years after the prior one where, although the Earth-coalition won the prior conflict, their Glowie Operative mentioned earlier would lead a second resistance, this time agaijst occupying Earther forces, which ensures Ganymede is independent. A government led by the Saturnian moon of Titan swoops in and ends up subjugating Ganymede.

While this is happening, Earth and Mars are at each others throats but then a coalition led by Titan decides to cut off the supply of fusion fuel to the entire solar system (Helium-3), which cripples both Earth and Mars’ fleets. Earth and Mars put their differences aside to stop Titan from controlling the entire solar system.

A subplot to the first story would be the Earther Glowie falling in love with a Ganyemedeian Rebel girl, and deciding to betray his own government after she is abducted by the Earth-coalition military (the Earthers never cared about Ganyemede’s people, they just wanted to stop Mars from controlling it).

Trope. I wanted to add a third superpower, and honestly, where would such a superpower come from? It seems likely that after Mars, Titan could be the next target.
I guess it also made worldbuilding sense because Titan controls the export of fusion fuel; and the even water, to the asteroid belt and Mars’ vassals.
The Earth coalition tries to become independent from Titan’s export of fusion fuel and ice by opening up more operations near Jupiter, but a pre-emptive strike by Titan knocks out their refineries. So both Earth and Mars team up to kick Titan’s shit in

I’m already writing a short story from the perspective of a Titan infantryman stationed on Mimas as the war comes to a close. The Earth and Mars fleets have pushed Titan’s forces back to the Saturn system, and the war is pretty much lost. I’ll post it on /sfg/ when I’m done.

It's not used on any useful scale. It's also more trouble than it's worth, since you have to process it AFTER its been in a reactor for it to be useful as a fuel. Unless you have well operating fast spectrum reactors or fucked on uranium like India then uranium is better is every way.

>>15485670
If anything I bet Mercury would make a better nation planet with abundant solar and raw materials. Where as Titan has no easy way to access large amounts of raw material other than methane and He-3 I guess. But then with Mercury's close proximity to the Sun is there a way to possibly just "scoop up" some solar flares that have He-3?

>>15485733
This one is good

>>15485767
watch the fox news segment retard. NON HUMAN CRAFTS

>>15485774
maybe, but thorium is way more abundant

>>15485733
Here anon

>>15485820
You can literally leech uranium out of salt water

>>15485820
And? Uranium is still quite cheap. It may make sense to move to Thorium later, but for now Uranium makes more sense.

>>15485803
Mercury is so close to the sun that there's literally no point in building nukeplants. Solar panels get like 9kW/m^2.

>>15485832
you can leech anything out of the sea, but its not worth it

>>15485836
i guess, but isn't it like 200 years of uranium deposits vs 10k years of thorium or something like that
200 years is quite a long time though

>>15485853
He-3 only for means of export not for local power and since you'd have so much energy from the sun maybe that's what makes economically viable for harvest on Mercury

Something I've wondered for a while. Why aren't nuclear batteries energy positive?

>>15485863
>Why aren't nuclear batteries energy positive
What do you mean? In what sense?

>>15485863
not really sure what you mean by nuclear batteries, but you could say RTGs are "nuclear batteries" and they sure as fuck are energy positive
oh they are actually a type of nuclear battery
maybe you are confusing something here

>>15485863
because I fucking SAID SO

>>15484957
Japanese hierachical culture does not allow for any younger engineer to voice complaints or push for changes that can prevent disaster or catastrophe. Fukushima's nuclear disaster's retrospective report basically outlined that this disaster ONLY REALLY TRULY HAPPENED because Japanese governing bodies are so deeply regulatory captured that smart decision making has no chance of actual success and ass kissing mentality ie ego/nepotism is so rampant that leadership will withhold critical information or allow easily preventable events to exacerbate to the point of sovereign scale disasters in order to protect their position rather than to lose face among peers and in front of leadership which expects absolute compliance to their authority.

Basically, the ALOS-3 satellite's failure to H3 launch could have been 100% prevented, but old men in suits have their heads so far up their asses, their lips come out of their own mouths and the words are said twice in demand of subservience to generational authority.

>>15485908
In the sense that they produce more power than is spent manufacturing them.
>>15485931
Yeah I meant RTGs. I thought the refining and construction wouldn't make them actually worth building unless you have no other option.

>>15485183
>On May 11, the European Space Agency announced a "Commercial Cargo Transportation Initiative" that would see one or more providers develop the capability to deliver 2 metric tons to the International Space Station by 2028

What are they going to price this at? Higher than a Starship that can do 100T to the ISS? Are they on drugs?

>>15485708

>>15485854
We could use the uranium a lot longer if we didn't limit ourselves to reactors that required enriched uranium. So-called "nuclear waste" is full of potential fuel.
Fuck Jimmy Carter.

>>15486081
well the idea is to foster private european space companies, basically have a closed market for certain payloads so european companies might take the same route that spacex did
but one of the problems is that they aren't saying how much they will pay for the cargo and are only giving 2 mil to to companies for preliminary design
almost seems like set up to fail, then they can go and say "we tried it, didn't work" and continue to give all contracts to arianespace

> By contrast, for the initial phase of its program, the European Space Agency is putting up a total of 2 million euro to support two companies with preliminary design and fundraising efforts. (See a list of potential bidders.) The benefit of this is clear: It allows ESA to start a commercial cargo program long before its next "ministerial" meeting in 2025, when it can ask member nations for more significant funding to support the cargo initiative.

>But there is a serious downside, as well. While there may be more funding in the second round, the European Space Agency is counting on private companies to raise money, develop test articles, and procure a launch independently for a 2028 demonstration mission now. This will easily cost hundreds of millions of dollars—all for a chance to compete for future cargo supply contracts.

>>15486125
I just want to live in a cabin powered by a battery that lasts decades man.

>>15486079
Why would you think that? The EROI on nuclear fuel sources (including RTG's which are still enriched, just not completely) is quite high.

Nosecones for S36 and S37 have been spotted, there are currently 13 Starships known to be in development/testing.

>>15486175
For reference.

>>15486079
You don’t expend the energy to build an RTG because you want to power a car or a house, you build it because you have a spacecraft that is going to the middle of Bumfuck Nowhere, Solar System and there is pretty much 0 sunlight. And all you really need is a measly few hundred watts of power anyways. You don’t really give a shit about energy in/energy out, as long as it’s in your spending budget
As an aside, the soviets used some RTGs in antarctica. Not sure what they powered though. Presumably low-power science equipment. I’d be surprised if they powered the camp

>>15486175
>>15486184

>>15486303
Copelets always resort to memetechs that will never work well in our lifetimes like fusion, plasmag or any FTL machine ever (cant break the laws of physics dumb fucks).

>>15486202
Are we talking actual lighthouses, or a little box with a dingy fluorescent bulb for aid in navigation? The wikipedia article for Beta-M isn’t clear. It says it has a 10 watt output so I assume it’s just powering a single little light

>>15486268
It's a glowing disinfo campaign so it's not going to blow over.

>>15486316
>Can't break the laws of physics
What law says nothing can go faster than the speed of light in a vacuum

>>15486316
going faster than light is not actually against relativity, you just can't accelerate past the speed of light
this might be a pointless distinction, but FTL is not actually strictly breaking the laws of physics, nor is going back in time)

you know what that means? it means there is zero fucking evidence.

Sabine simply points out that if there's a preferred frame, a lot of the FTL time paradoxes might go away. She then asserts without evidence that this frame is the universal comoving frame.

From the story he's telling it wasn't like that. He worked for the NRO on the UAP advisory board, there were never any samples to sneak out.Hes presenting this as a report to Congress about improper oversight.

>>15486542
Do these look like the faces of mercy?

>>15486551
They are more than 50 percent solid by area, at least. So they are more "dirt" than "air." But I thought one step and your momentum would punch right through it. You won't "fall" through them unless you are a flat earther

>black ginger

spaceflight

>>15486547
I assume gravity is extremely weak, so probably not.

>>15486551
They're co-orbiting debris, not solid. Those spikes are more like fountains of material that get wonked onto slightly inclined orbits thru wave propagation thru the rings and gravitational interactions. They don't last for more than half an orbit.

>>15486144
Wait, are they putting out contracts for euro cargo to the ISS, testing in 2028? I guess they are betting on the station being perpetually renewed, because it would be silly to test new vehicles for a station that they keep trying to cancel and let fall out of the sky.
