LRV-1 had a little plaque on the side of its dashboard box, similar to the plaques left on the descent stages. Were any plaques or insignias mounted on LRV-2 or LRV-3? I've never seen any.

Did the LMP ever, at any point, drive the LRV?

>>11340844
There's a difference between having thoughts that are different from a community, and going to a community specifically to spread ideas to upset them. The first is reasonable, the second is trolling. Nice try, janny.

>>11340683
I like the Axiom station but hope that we will see a second commercial station too, whether by Bigelow or someone else. Redundancy and competition are important.

>>11340840
I know that, I'm just curious why that's not second nature to spacefags. You'd think it would automatically fall flat, they'd go "wait, that's..." and then move on, but autists get pissed that someone doesn't believe conventional wisdom that they, the autists, take on faith. They go into rages. They gain missionary zeal. Why is it so personal to them?

It's because they're not spacefags, they're conspiratards. There is nothing you can do to change the mind of a conspiratard, not even strapping him to a fucking rocket and launching it. Or they're outright trolls and only care about riling people up. Either way, arguments will not faze them.

>>11340901
>Would really like for SpaceX to have a competitor

Depends what you mean by competitor:

Arianespace and Roscosmos’ commercial subsidiaries are competitors against SpaceX for the international commercial market, small satellite launchers like Rocket Lab are competing against their ride share program and ULA is a competing against them for domestic government payloads. BO would be SpaceX’s first American competitor for large commercial payloads and the first competitor also using a RLV.

>>11340916

New JWST update from GAO:
https://www.gao.gov/products/GAO-20-224
GAO's forecasting it will launch next year in July. They say there's some problems though. They found that a travelling wave tube amplifier built by a subcontractor was built shoddily, one of the telemety processors was acting a bit funny. They're also a bit worried about air trapped in the sunshield membrane during launch, so they're doing a test of a new fairing valve during a launch in spring. They found that 501 of the bolts they installed may not be and may pose a mechanical strength risk. Grounding straps on the spacecraft’s momentum flap came loose during vibration testing and needs to be removed, repaired, and replaced before further vibration testing can take place. Only half of a redundant non-explosive actuator on one of its membrane retention devices fired as planned during a test. It's redundant, so it still would have worked, but there are 180 actuators that need to fire so one not firing with both is a bit ominous. At least nothing has gone horribly fucking wrong like fucking bolts fall off during a test.

>>11341042
Now that India is a superpower, they'll add all that extra stuff later this year, right?

>>11340990
it's been shown you can use teleoperated robots to build a landing pad from sintered bricks:
https://spectrum.ieee.org/automaton/robotics/space-robots/hawaiian-robot-landing-pad-construction
Problem was that the pad they made got destroyed by rocket exhaust when they tested it. So there's work that needs to be done. Automating brick production needs to be done too, but it's not a ridiculously hard problem

Heard from a friend working on it that the goal is just to get the damn thing sent to Kourou, because then congress can't cancel it.
>> normies will reee and NASA will get gutted
nope, that won't happen. In an ideal world, Northrup Grumman and all the other contractors responsible for workmanship issues would get reamed. What will actually happen is a couple subcontractors will get scapegoated and Northrup Grumman will get a slap on the wrist. The big defense contractors have mastered the art of maximizing costs, underdelivering, and lobbying. I've heard rumors that during the cold war they had engineers sit at desks all day acting as secretaries because the more people they had on the project the more money they would get.

What’s this cryogenic strength test meant to show?

I don't see how they are going to be profitable with 2-3 launches of private astronauts like people are saying. Are they expecting 6-7 astronauts per flight? That's less than a billion dollars a year. Is that even going to cover the cost of launching people to the station?

>>11341404

>>11341415

>>11341425

>>11341454
>you can't crash a plane into me if I fly away!

>>11343036
I know. Boeing doesn't have much room to complain since they're the most expensive contractor in commercial crew, both on a cost-per-seat basis and the total amount of development funds they received. Boeing also gets favorable funding from SLS where they were routinely behind schedule and failed to meat milestones, yet were awarded by NASA the milestone reward funds. This is generally a bad practice and it's shameful that both NASA and Boeing engage in this behavior regularly. Now, NASA telling Boeing to finally take on some personal losses for the second test launch could be a sign that NASA is reevaluating it's relationship with Boeing for the better. I hope so.


TL:DR, I know, Boeing deserves it and then some

>>11343036
>Boeing is complaining about needing to pay for that potential launch out of pocket instead of having NASA pay them for it

Boeing isn’t even complaining, they’ve already put aside a large sum of their own money to perform a do-over if needed. That’s why I’m calling them retards for complaining...

>>11343062
> NASA telling Boeing to finally take on some personal losses for the second test launch could be a sign that NASA is reevaluating it's relationship with Boeing for the better.

Nice fantasy, but it’s literally just Boeing and NASA following the law. The contract for commercial crew is fixed-price, meaning any extra fees required (e.g. an extra test flight) have to be payed out the contractor’s pocket. Also, you’ve assumed NASA will make Boeing do another test flight, this is just Boeing preemptively preparing for that possibility.

Unlike Spacex, Boeing is actually vital to the national security and making it look bad and less competent is a dangerous game no politician will be willing to consider.

SpinLaunch fucking exists

Last summer, a secretive space company took up residence in a massive warehouse in the sun-soaked industrial neighborhood that surrounds Long Beach Airport. Reflections of turboprop panes flit across the building’s mirrored panes. Across the street a retro McDonnell Douglas sign perches above the aerospace giant’s former factory, and just around the corner Virgin Orbit is developing air-launched rockets.

It’s a fitting headquarters for SpinLaunch, a company breathing new life into the decades-old idea of using giant mechanical slings to hurl rockets into orbit. The man behind this audacious plan is the serial entrepreneur Jonathan Yaney. For years he ran SpinLaunch out of a former microprocessor plant in Silicon Valley, down the road from Google. Now the company is ready to open a proper rocket factory, where it will churn out launch vehicles and, if all goes well, take its first steps into the cosmos.

When I visited this past fall, SpinLaunch employees were still unpacking from the move. As we walked among giant sheets of steel, Yaney explained how his launcher will work. A centrifuge large enough to contain a football field will whip a rocket around in circles for roughly an hour, its speed steadily ramping up to more than 5,000 mph. The vehicle and its payload—up to 200 pounds’ worth of satellite—will experience forces that, at their peak, will be ten thousand times stronger than gravity. Once it’s spinning at launch speed, the centrifuge will release the rocket and send it screaming into the stratosphere. At the threshold of the cosmos, it will fire its engine for a final nudge into orbit.

The idea that an object weighing thousands of pounds can punch its way into space after spinning in circles on Earth’s surface can be hard to fathom. It might even sound crazy, and the company has a lot to prove to shake its critics. So far it has managed to spin an 11-pound dummy payload at more than 4,000 mph and send it crashing into a steel wall. Between those tests and the edge of space, however, are roughly a hundred miles and a whole lot of air resistance. Never mind the engineering work needed to build a centrifuge 100 yards wide, with an arm strong enough to support a roughly SUV-sized rocket.

Yaney hopes this is the year he achieves vindication. The company plans to conduct its first suborbital launches this winter at a new test site in New Mexico. Assuming the system works, Spinlaunch promises to reduce the cost of sending small satellites into space by a factor of almost 20. But the bigger deal may be its launch cadence. Yaney predicts the mass accelerator will be able to do five launches a day; most rocket companies can’t do that many launches in a month. In the era of mega-satellite constellations, which will see thousands of small satellites sent to low Earth orbit over the next decade, Yaney believes Spinlaunch’s time has come.

>The vehicle and its payload—up to 200 pounds’ worth of satellite—will experience forces that, at their peak, will be ten thousand times stronger than gravity.
how the fuck are you supposed to accomplish this? won't any satelite just compress under that force?

Four Million Bucks and a Crazy Idea

Like so many space entrepreneurs, Yaney has been obsessed with the cosmos all his life. But it took until 2014 for him to try to turn his passion into a career. He was working at Titan Aerospace, a solar-powered drone startup founded by his brother Maximus, when Google decided to acquire it. As he contemplated what to do next, Yaney’s mind turned again and again to a Cold War military project called HARP, in which the United States Army used a giant gun to shoot projectiles into space. HARP proved it was possible to get to space without a rocket, so Yaney set out to build a kinetic launch system of his own. He cobbled together a working proof of concept, essentially a motorized sling that could spin a bullet-sized projectile up to hypersonic speeds. He took it to a few angel investors and secured a small amount of funding.

But he needed help. In late 2014 he called up his old roommate from boarding school, Ryan Hampton, a whiz at construction and industrial operations. Hampton was running underwater welding operations on oil rigs in the Gulf of Mexico when Yaney made his pitch. As Hampton recalls, “He said, ‘I’ve got 4 million bucks and a crazy idea, want to come with me?’”

Hampton couldn’t resist. In January 2015 he flew out to see what Yaney had built. It wasn’t much. Yaney showed off his tabletop centrifuge and shared his spreadsheets full of calculations. But Hampton was hooked: He saw that SpinLaunch was “gonna be one hell of a project,” and signed on as employee number one.

Yaney had the ideas and Hampton the construction skills, but they still needed some aerospace engineers. So on a warm spring day a few months later, the pair climbed into Yaney’s Cessna and flew out to the edge of the Mojave desert, where dozens of college students had gathered to test their rockets. The duo was hoping to recruit a few of them.

>>11343508
Have you considered that I am that anon?

One of their targets was David Wrenn, a junior at San Diego State University. He had been doing phone interviews with SpinLaunch for weeks, and the circumstances weren’t ideal for an in-person interview. “I had been awake for like 36 hours at that point, so I was semi-insane when I met Jonathan,” Wrenn recalls. Still, the meeting went well. He took a leave of absence from college and flew out to San Francisco to join SpinLaunch, where he now works as a senior mechanical engineer.

Hampton says the early days of SpinLaunch reminded him a lot of life on an oil rig. Employees lived and worked at an old microprocessor plant SpinLaunch had taken over just down the road from the Googleplex. When Wrenn arrived, the living spaces were spare. “At that point the kitchen was like a microwave and a plastic table,” he says. “You had to have a lot of vision or nothing to lose, one or the other.” When they weren’t working, the SpinLaunch crew lifted weights together in a makeshift gym, watched movies in a “home theater,” or relaxed around a fire pit—the converted remnants of Yaney’s original tabletop centrifuge.

The team quickly ran into engineering challenges. The centrifuge they were building had to sit in a massive vacuum chamber to protect the system from air turbulence and stabilize it as it spun. When they approached contractors to build the chamber, they got one bid—with a price of $20 million.

So the SpinLaunch team decided to build it themselves. As an underwater welder, Hampton had become an expert at crafting airtight seals, which translated well to his new task. Yaney ordered a few vacuum pumps off of eBay and $500,000 worth of steel, and the team set out to build the sixth-largest vacuum chamber, by diameter, in the world. It took them eight months. “I think we all began to realize that there are so many things in science and engineering that have to be uncovered, simply because people don't try them,” Yaney says.

those are significantly slower, this is designed to launch a very heavy object at 2.2 km/s

>>11343515
>skeptical investors and potential customers who didn’t believe a payload could withstand the extreme forces. The team sent solar cells, radio systems, telescope lenses, batteries, GPS modules, and control computers whirling at high speeds; they all survived with little to no damage. In one test, Yaney attached an iPhone to the tether and spun it up to nearly 4,000 mph. Afterward, he used the phone to FaceTime a colleague. Each test was a step, however small, toward space.
or maybe not? idk I feel like an iphone would break with 10k g's or I guess less at this speed, but apparently stuff does survive? What about fuel though, all the things they tested are "solid state", if they plan to send something with a rocket engine like they say then I don't know how liquids or compressed gasses will act here

My idea for the next gen of spess station. Take the air-breathing satellites ESA is working on, and dangle them from the bottom of the station with massive retractable tethers. Pull a nuclear reactor behind the station. Skim hydrogen, nitrogen, and oxygen. Use it for fuel, water, and atmo.

>>11343540
>>11343544
how fast do these air breathing satellites have to move to stay in orbit compared to the station though? I imagine they would get out of sync pretty quickly so you can't really tether them without constantly burning to maintain orbit

>>11343551

>>11343570
There's a physical limit to the speed you can get due to the explosion wavefront speed or something like that. A staged light gas gun can get you faster than a conventional gun but there's still a physical limit. I guess this thing can get a higher exit speed. There's also the size issue - either a conventional gun or light gas gun has to be a fucking massive long tube. This thing is likely more manageable.

My question though - does the vehicle come out horizontal and then swerve upwards? Or is it built on a slope?

>>11343574
So basically something inspired by the SLS

>>11343603
Ah yeah looking at the photo I see it's on an angle

>>11343603
>higher exit speed
Little point in a dense atmosphere since most of it would be eaten up by air drag anyways by the time it reaches space

>>11343561
Oh they would definitely experience fractional gravity. How much depends on what altitude the space station orbits at and what altitude(s) the breathers would fly at. But even the non-meme ones ESA wants to build will need to burn constantly to overcome drag. The question, beyond the immediate research of whether air-breathing satellites are possible at all in the first place, is how much excess matter they can collect beyond what's needed to overcome their weight, drag, and the weight the tethers would exert on the station; if that would negate the need for water and fuel to be resupplied from the surface. Mathematically you could orbit the station at a superorbital velocity to balance the forces and not require constant upwards thrust, but that would add more tension to the tethers, and I assume that, in this future where these devices work, it'd be more efficient to just use thrusters than try to constantly balance such a monstrosity.

for a straight tube to get the same speed as SpinLaunch there's a simple equation
[math]x = \frac{2200^{2}}{2a}[/math]
'x' here is the length of your launcher and 'a' is the acceleration (in m/s[math] ^2[/math])
to hit the 35 degree angle, you need your tube to descend a little over half as deep as the length

can someone explain the boeing subcontracting thing to me?

>>11343846
This WEBM doesn’t show just Boeing’s subcontracting, but all the subcontractors providing parts for SLS and Orion. SLS obviously has more subcontractors than your average aerospace project because it’s being managed by NASA instead of a company and because of the need to have jobs in many congressional districts to garner widespread political support for the program. But subcontracting itself is really common in the rocket/spaceflight industry due to the specialisation, complexity and high quality of the parts needed. For example, all of NASA’s crew capsules have parachutes made by the subcontractor Airborne Systems, both Ariane and ULA’s fairings are manufactured by Ruag (although the latter gets them built in-house), many rocket builders buy their engines off companies such as Aerojet Rocketdyne and Starship’s trademark stainless steel isn’t machined in-house, but bought from established steel mills.

so here's what gets me. How the hell are they going to decouple the damn thing from the arm? Force on the arm's as much as some ships weigh. I doubt a mechanical grapple will work. The explosive bolts that held the shuttle on the pad have about the required strength, but ideally we'd use something with a high specific strength. So what they might be doing is wrapping the projectile in that same composite they made the arm from and break it to release the projectile. This irritates my reusability autism.

story time /sci/

gather round and listen well.

Long ago, there existed a blue green planet, in between earth and the asteroid belt.

IT had a magnetic field, oxygen, an atmosphere, and gentle warmth.

Then, one day, someone decided to construct a conductive tensile truss from the surface into orbit.

The resulting van alen belt and magnetosphere interactions turned the tower into plasma in a fraction of a second, and the plasma channel continued conducting energy until the magnetosphere was spent.

It carved a great big, wide, and long trench on the surface of that planet.

the resulting chaos left that planet completely uninhabitable, and incapable of sustaining liquid water upon it's surface.

do you know of the story that I tell?

have you heard it before, even as a distant form of memetic mutation?

I can't remember seeing anyone talk about doing that before, which probably means it's a silly idea, if only in terms of scale, and it might never be worth the effort.

Mars is not for everyone. Just like America wasn't for everyone. The ones who will go to mars are those that see a future there. For the well to do people, Mars is far off fantasy. For those without much hope on earth, for those with hopes and dreams of a better life outside of Earth, Mars will be the perfect place to go to. They will give up material comfort for freedom.

Mars is likely to become the new US after the current US becomes mongrelized by spics, and the values that made it great get demolished in the name of "progress". Mars has a minimal atmosphere that enables some level of aerobraking, while not contributing a whole lot to extra fuel costs to go to orbit, which is way easier anyway due to 0.38g of gravity. Barring some fuckery from Earth-based forces in the initial setup phases, Mars will have access to both untapped easily-accessible resources on the planet, and the entirety of the asteroid belt.
The argument that moving to Mars means "giving up real food" doesn't really work when the elites want to shove insects down the throat of all plebs on Earth anyway, and you know they'll manage to do it through enough marketing, like they did with fags and trannies. At least on Mars/space colony you'll be free, as Mars development will force major investment in self-sustaining habitats that will enable people to not be dependent on some central government for goods or services like electricity or food. Difficult to force your opinion down someones throat when they are completely self-sustaining and have guns.
Worst case if Earth starts to act big, Mars dumps 100 Starships worth of Mars sand in LEO, cutting Earth off from space completely for decades. Especially if all of the bright and ambicious minds already left for Mars and there's no one left to make a ship capable of cutting through the Red Blockade.

The martians should also attach rocks and shit to their limbs so their bodies do not atrophy. Say what you want, but earth people do have a natural advantage unless martians find a way to keep their muscle mass equivalent to or even more than on earth

>>11344474
I wonder how tall humans could grow in that gravity?

>>11344479
I think the bigger limiting factor for bone length is muscle length. Those don't arbitrarily keep getting longer.

>>11344483
but they might get bigger around?

besides, whales, elephants, and dinosaurs are pretty big, and their muscles work (or worked) just fine.

>>11344479
Mars has 38% of the Earth's gravity, so I'd say that people could probably grow 2.63 times taller. However, I think we should either induce weight so we don't become spindly or simply edit our genes to simply keep muscle production at a high.

>>11344488
>or simply edit our genes to simply keep muscle production at a high.

there's a lot more to adapting to 0.38g than just muscle DNA, dood.

Why not just rotate groups of people to Mars orbit every few months to undergo 1g spin while they're still growing? Fly up for a month of spin-therapy, fly home and recoup for a bit before your next session. Viable, or retarded?

>>11344491
We have a lot of data for human physiology in 1g and a decent amount for ~0g. We have no idea what happens long-term in between those points.

For all we know, 10% earth gravity could be enough for the human body to properly orient to the environment and develop almost normally. The relationship between gravity and muscle/skeleton development might not be linear. We need actual experiments, which is why it's stupid there are no current plans for partial-g stations in LEO.

>>11344591
Part of NASA's microgravity research is trying to find the biological pathways that respond to things like the strain of exercise or gravity. If we can sort that out it would be possible to administer a pharmaceutical treatment that, if combined with moderate exercise, might make living in very low gravity work very easily. You would still want some gravity though, because otherwise the brain isn't going to learn how to use the inner ear properly.

The problem is that people living on other worlds SHOULDN’T “develop normally”. They should develop like they’re living on another world, with the morphological differences that implies.

>>11344497
>Why not just rotate groups of people to Mars orbit every few months to undergo 1g spin while they're still growing?

Why?!
They’re Martians. Martian gravity is what they ought to be adapted to, not the gravity of Earth. To them, Martian gravity is “1g”.

We'd want to keep people 'Earth normal' up in space for two basic reasons, number one being that an 8 foot tall person is hard to stuff into a spacecraft unless you make everything bigger, and number two a normal person on pretty much any other object in our solar system is effectively super human, with a very large strength to weight ratio.

>>11344350
There's actually a distinct chance it would start to cook Earth's surface. That is one of the doomsday steps after a large meteor impact. All the debris it blasted into LEO comes raining back down and its heat on entry cooks everything down to 2 inches into the soil at like 500F temps. So, it'd depend on how much sand there is and how much hits at any one time.

>>11343692

>>11345767
at that point why even bother with the oxidizer and just nuclear thermal your way around?

>>11345763
Not him, but the problem that far out is and will always be sunlight, aka heat. Starting a runaway greenhouse effect might be tempting at first, but you'll end up with an even longer period of having to scrub that shit, so you'll be looking at some kind of sunlight lens or something.

>>11345767
Yeah, that's totally not a temporary solution with long term nasty side-effects. Congratulations. You've melted all the water ice on Titan by nuking it, irradiating all the water in the process, now it's rapidly turning back into radioactive ice. Now what?

>>11345772
NTRs have poor TWR and won't be suitable for landing. The issue of radiation also makes them difficult to dock around, having a chemical engine to use when the reactor is shut down would be useful in approaching stations. Not every spacecraft needs NTR. It's hard to fit a reactor on a small vehicle, like a buggy, but a fuel cell based on methalox or hydrolox would be useful. Chemical fuels are also generally safer to store and use than fissile fuels, which gives them greater flexibility in applications.

Nuclear is amazing for spaceflight, but it isn't a cure-all.

Much more proven then anything we plan to do one mars and you only need the first heat source to start the fuel production.

>Yeah, that's totally not a temporary solution with long term nasty side-effects. Congratulations. You've melted all the water ice on Titan by nuking it, irradiating all the water in the process, now it's rapidly turning back into radioactive ice. Now what?
I didn't mean literally nuking Titan, dummy. I meant using a reactor to power the facilities needed to generate chemical fuels.

>>11345780
water will absorb a stupid amount of neutrons before anything bad will happen and the worst thing it does is turn into Florine

>>11345794
Generating fuel is hardly making thing habitable as implied in the original post, is it?
If it's just generating fuel, we may as well start scooping shit from the gas giants.

>>11345797
And as for oxidizers? Saturn has enough snowballs in orbit to suit that purpose.

>>11345797
If you can generate endless fuel on site you can power artificial gravity which is a pipe dream elsewhere with current energy tech, titan's atmosphere solves the rad problem and as long as you keep the fuel flowing it allows far easier development then anywhere else in the solar system.

>>11345797
Having easily stored and usable fuel is necessary to make any place livable. Also, other chemicals can be produced as needed, such as oxygen to breathe which is pulled from the water ice on the surface of Titan.

>>11345805
Saturns rings are primarily composed of water ice chunks. Sling that shit anywhere in the solar system and we can produce just about all the oxidizer we'll ever need. Fuck Titan. Easier to produce and move shit around outside it's gravity well anyway.
