>>11489421
but they are going to launch in less than an hour anyway?! I guess it is too late to cancel the launch contract or something?

>>11489491
I don't know how it works out either. Maybe they're trying to keep it going as long as possible while praying that some sucker buys them out?

we gonna break 150 launches this year?

>>11489501
>Maybe they're trying to keep it going as long as possible while praying that some sucker buys them out?
Probably this, though they might be trying to buy some time, since filing for bankrupcy isn't as simple as it sounds

>>11489523
maybe

>>11489523
no. Even in a typical year, a large chunk of scheduled launches are delayed. But with the economic crash and Corona shutdowns, a whole bunch more are going to be delayed or canceled. India has suspended all launch operations, for example, and ESA has shut down their Kourou launch site.

there's plans for doing that "eventually" but now that they're buying BE-4 it probably isn't worth it

>>11490136
>there's plans for doing that "eventually"

There’s definitely plans to do it, they just have to wait until 2022 to start working on it because that’s when LOFTID, which is essentially a proof of concept for SMART will be launched and tested.

https://www.nasa.gov/feature/goddard/2019/inflatable-decelerator-will-hitch-a-ride-on-the-jpss-2-satellite

>>11490149
Aka no such plans because nasa isn’t going to give them a contract for it

>>11490155
>The Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) is a public-private partnership between NASA’s Space Technology Mission Directorate and United Launch
Alliance (ULA). The LOFTID project is poised to revolutionize the way NASA and industry deliver payloads to a planet’s surface or into orbit, utilizing aerodynamic forces instead of propulsion. Since NASA’s inception in 1958, the agency has relied heavily on retro-propulsion (rockets) and rigid heat shields to decelerate people, vehicles, and hardware during orbital entry, descent, and landing (EDL) operations.
After more than a decade of development
of the Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology, including two suborbital flight tests, the LOFTID orbital flight test is the next logical step. Return from orbit provides an entry environment relevant to many potential applications, paving the way for its use on future missions. HIAD technology can enhance, and even enable, larger missions to higher elevations at Mars. It can also be applied at Earth, providing capability for International Space Station (ISS) down-mass, or even enabling return for free-flying orbital manufacturing. Recovery of spent launch vehicle assets for reuse, such as ULA’s plan to recover their first stage booster, can reduce the overall cost of access to space.

>>11490191
>Wha has this to do with turning “smart” into a reality?
>Nothing, it’ll never happen

>The LOFTID Reentry Vehicle (RV) is a secondary payload hosted on an Atlas V launch vehicle, and will be delivered to its reentry state by the Centaur, the Atlas V second stage. The RV is stowed within a primary payload adapter on the Centaur, such that the primary payload adapter can be released and separated to expose the stowed aeroshell for deployment while the RV is attached to the Centaur. The RV is inactive and powered off during the launch and delivery of the primary payload. After the primary payload has been delivered to orbit, the Centaur performs a deorbit burn to reenter the Earth’s atmosphere. After the payload adaptor is jettisoned, the RV is then powered on, the packing restraint is released, and the aeroshell inflation is initiated. The inflation system begins a “soft start” and then full inflation, delivering nitrogen inflation gas from pressurized tanks provided by ULA. When the aeroshell is fully inflated, the Centaur attitude control system spins up the spacecraft and performs a final pointing adjustment before releasing the RV on its spin-stabilized reentry trajectory. The Centaur then performs a divert maneuver to avoid re-contact with the RV as the Centaur burns up on reentry. The RV reenters the atmosphere on the prescribed trajectory, and decelerates from hypersonic down to subsonic flight. Throughout the RV flight, a real-time beacon transmits minimal data packets to a satellite network, while data from instrumentation, cameras, and other subsystems is acquired and processed, sending duplicate comprehensive data to both an Internal Data Recorder (IDR) and an Ejectable Data Recorder (EDR). After reentry, the RV ejects the EDR, which is buoyant and provides a GPS locator signal for physical recovery from the ocean surface.

>>11490206
So 2 years from now they will do a balloon test with hardware totally unrelated to anything else

This is just some technology demonstrator which is one of the ways NASA turns a project that should only last a year into 2 decades of research and a billion dollars

>>11490225
>So 2 years from now they will do a balloon test with hardware totally unrelated to anything else

It’s literally a full-scale re-entry test for the inflatable heat shield SMART will use, stop with the mental gymnastics.

But it isn’t, it’s just some small scale 6 meter demonstrator, which “can be scaled in the future”

ACES is not going to happen and neither is SMART
Their long term future plan is just to declare bankruptcy and retire

>>11490390
Centaur V has many of the ACES upgrades baked in, like the hot gas-gas RCS thrusters and such

>>11490390
>But it isn’t, it’s just some small scale 6 meter demonstrator, which “can be scaled in the future”

LOFTID is 6 meters in diameter, which is wider than Vulcan’s 5.4 meter core. NASA have stated it can be scaled up, and their correct, LOFTID itself is just a scaled-up version of earlier, smaller inflatable heat shields that have been tested, so why not scale up more in the future?

>>11490405
I’m pretty sure they plan to phase ACES’ IVF technology (which is the only thing CV is lacking) in as part of the NSSL Phase 3, which is all about “new capabilities”.

>>11490426
and then the only difference between Centaur V and ACES will be the insulation for indefinite cruise time

>>11490419
wait, this isn't a new technology they're demonstrating? it's just the latest in a series of progressively larger prototypes?

>>11490431
Yes and that

>>11490419
Inflatable reentry vehicles is nothing new, if they were serious about it then they wouldn’t be waiting for demonstrators and after their rocket starts launching

Instead the plan would be to always recover engines

>>11490437
>it's just the latest in a series of progressively larger prototypes?

>NASA launched an inflatable heat shield experimental spacecraft on 17 August 2009 with the successful first test flight of the Inflatable Re-entry Vehicle Experiment (IRVE). The heat shield had been vacuum-packed into a 15-inch-diameter (38 cm) payload shroud and launched on a Black Brant 9 sounding rocket from NASA's Wallops Flight Facility on Wallops Island, Virginia. "Nitrogen inflated the 10-foot-diameter (3.0 m) heat shield, made of several layers of silicone-coated [Kevlar] fabric, to a mushroom shape in space several minutes after liftoff." The rocket apogee was at an altitude of 131 miles (211 km) where it began its descent to supersonic speed. Less than a minute later the shield was released from its cover to inflate at an altitude of 124 miles (200 km). The inflation of the shield took less than 90 seconds.

>Following the success of the initial IRVE experiments, NASA developed the concept into the more ambitious Hypersonic Inflatable Aerodynamic Decelerator (HIAD). The current design is shaped like a shallow cone, with the structure built up as a stack of circular inflated tubes of gradually increasing major diameter. The forward (convex) face of the cone is covered with a flexible thermal protection system robust enough to withstand the stresses of atmospheric entry (or reentry).

>In 2012, a HIAD was tested as Inflatable Reentry Vehicle Experiment 3 (IRVE-3) using a sub-orbital sounding rocket and worked.

>In 2020 there were plans to launch in 2022 a 6 m inflatable as Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID)

New nuke proposals have arrived. What do you fags think of this?

>>11490350
Slaughterhouse Five.

>>11490477
First of all, this proposal is a year old, secondly it uses Nuclear Electric Propulsion..., third and finally it’s a NIAC, meaning it’s basically just a futuristic study. An actual nuclear mission to get excited about is whatever NASA and the Department of Energy are currently working on with actual funding.

>>11490498
>non chemical or ionic propulsion
>happening with NASA

>>11490513
You’d be right up until now, considering NASA hasn’t had funding to develop nuclear propulsion since the 1960s until 2019. Also, who else but NASA will the government allow to put fissile material on a rocket? There’s currently only a single US rocket allowed to carry nuclear material, even in the form of RTGs.

>>11490498
K, but ignoring all that, the real prize from that proposal is the lithium deuteride moderated low-enriched-uranium fuel reactor.

Kilopower would be great but it's reliant on high enriched uranium, weapons grade enrichment in fact. That's never going to be something easy to draw into mission plans because the fuel is so politically touchy to even talk about. Low enriched fuel on the other hand is manufactured in the thousands of tons per year, there's no issue with that.

>>11490530
Direct nuclear propulsion will be much easier once colonies independent of any earth government are formed.

>>11490542
Of course, but I want my nuclear powered flagship class Uranus and Neptune probes NOW god dammit

JWST was designed for Ariane 5; back in 1996, there were limited options for beyond-LEO launch vehicles with significant payload capabilities. In 2003, when the actual contract for building it was awarded, neither Delta IV nor Atlas V had proven themselves as reliable launch vehicles. Ariane 5 was the only vehicle that fit the bill.

>>11491106
But everyone who is going to space does speak Russian already. Learning it a part of the training. LK is not Soyuz, and the Moon landing was just a propaganda mission and a dead end which led the humanity nowhere. The original Venus flyby and "slow and steady exploration" concept was miles better.
>also wed have reusable energia boosters by now
Energia was built by Glushko, not Korolev.
Korolev wasn't some kind of ancient soviet spaceflight god, he had his share of mistakes, notably bying the Shukhov's hyperboloid meme with N-1 which turned out not to be as light as he hoped, and using it instead of just scaling the perfectly fine R-7 parallel layout he already had working, which could have been tested on a much smaller/cheaper stand. There were dozens of better engineers with better vision in the union. Mishin was a terrible lead, but that's just him.

That doesn't mean China "lacks a rocket to do anything past LEO" but I agree with your semi-related point about them needing bigger landers if they want to bring stuff larger than a desk up there.

>>11493618
Russia’s Moon plans are in a permanent state of limbo, so I wouldn’t read too much into anything unless an agreement is signed or joint program started.

>>11493690
Stop bringing Apollo. It was a single-launch mission to nowhere. Nobody is going to do single launch missions anymore for this, neither NASA nor SpaceX not anyone else. You land at least hundreds of tons of equipment, if you are going to do at least something useful and not just plant a flag, no single rocket is going to do this.

>>11493647
>>11493618
Technically both plan superheavy rockets, but lack the capability.

>>11493647
>>11493699
This >>11492625 will raise it’s orbit to 8,000km (MEO) for a high-speed re-entry test after it’s April launch on a LM-5B. So technically, the Chinese do have a crew capsule able to travel beyond LEO...

>>11493709
Not really. You just assemble it in orbit from smaller pieces and deliver fuel separately if needed. It's not 1968 anymore. With reusable rockets it will be even cheaper than with an expendable large one like SLS.

>>11493723
Oh neat, I had wondered what that was for.

>>11493618

>>11493726
B-but reusable rockets are just a meme. Blunderf00t said so!

>>11493734
No one did orbital rendezvous when the Lunar orbit rendezvous mission mode was selected for Apollo. But what was done after that was that tests were conducted to figure things out. Not just small meaningless tests for grants, actual implementation of hardware to learn something useful. If we're just going to limit our space flight missions to what has been done before, then we'll never leave this rock.

>>11493734
>No one has done an “assemble in orbit for BEO” mission
And? Does it make this impossible or what? Orbital assembly is mastered long ago.

So given the size of starship and the supplies needed for a large crew, is physically blocking cosmic radiation viable by just having all the cargo in the exterior compartments of the ship?

How many feet deep of stuff do you need to block radiation for a year?

>>11493700
Just like American ones, oh wait

>>11493750
Why not just dedicate a Starship for interplanetary travel and build an ice shield around it Magellan-style using moon-water?

>>11493750
You can design the crew compartments to be surrounded by water and that will take care of most of the radiation.

>>11493765
Because physics?

>>11490953

I thought minimizing dry weight is everything in spaceflight? How can increasing your weight be better than a more expensive but lighter heatshield, especially for an interplanetary craft?

So what happens to those 74 OneWeb satellites currently in orbit? They're pretty much useless since the constellation is very far from completion.

>>11493885
>I thought minimizing dry weight is everything in spaceflight?
No, and that's a poor mindset to have. There's more to spacecraft design that needs to be taken into account. Especially when reuse is a part of the mission.

>How can increasing your weight be better than a more expensive but lighter heatshield, especially for an interplanetary craft?
Well first, that's a prototype so dry mass isn't a concern for now. Second, I assume you're referring to the steel construction, that material can handle extreme heat loads better than lighter materials which means a thinner heat shield can be used and that usual ways of dealing with temperatures can be discarded which saves on weight. Also, steel is much more ductile than aluminum which makes the vehicle more durable, which is needed for reuse.

>>11493900
Thinner heat shield, maybe, but the perspiration liquid cooling system they're adding/need on top of that sure to add even more weight.

>>11493930
I thought they dropped perspiration cooling for just tiles? I think it was TUFROC?

>>11493885
I have no idea what the fuck I've talking about, but the reasoning I keep hearing is that the heatshield isn't so light because the aluminum isn't robust at extreme temperatures. I believe the entire space shuttle had thermal protection whereas the intention for starship is to have about half coverage that can be thinner.

But like >>11493900 said. It's a trade off. If your rocket takes more fuel and tops out at slower speeds, but it can still do the missions you need and its reusable, you've found the winning balance.

>>11493930
>>11493934
They did drop the sweating thing

>>11493885
>How can increasing your weight
Except you're not if you account for steel being stronger than composites at cryo temps and than aluminium at high temps, for a small fraction of the price while at that

>>11489376
Question: what is the best way to bring the cost of the SLS down?

>>11494068
Build them outside so they keep getting destroyed.

>>11493750
>How many feet deep of stuff do you need to block radiation
For cosmic rays, you need to be surrounded by a shell of water ten meters thick to provide equivalent shielding as exists on the Earth's surface. Nothing else works, magnetic fields in particular only divert solar wind and do FUCK ALL to block cosmic rays, the particles are simply too high energy. Mass mass mass is what you need for your ass. Of course, bringing field levels down to ambient on Earth's surface is overkill, you only need a fraction of that (but still several meters worth) to fit inside the maximum annual dose limits for nuclear energy workers, which would actually mean that those astronauts would be getting less dose than people currently do on the ISS.

>>11493892
Scrap em, deorbit, they're junk, waste of parts

>>11494068
Centralize manufacturing of all components within a single state.

>>11494068
Really isn't any way at this point other then what this anon pointed out
>>11494100
Reusable rockets are the future.

>>11494112
>Reusable rockets are the future.
Yeah I think so too, if NASA got behind it and manufactured all the components in a single state or even a single facility, the cost savings would be enormous. Splitting something up between 50 states just so everyone votes on it is fucking gay, stop it.

>>11494119
I believe the main reason why they can't do this is they would need congressional approval. That's why NASA seems so slow compared to private space companies.

>>11493930
>Thinner heat shield
Thinner on the belly, absent entirely on the backside.
Mass per square meter of the finished vehicle is structure plus TPS. If they did carbon composites, the TPS needs to be waaaay thicker and cover twice as much surface area. The carbon composite structure is also only marginally lighter than aluminum at best because of the amount of additional support structure needed for carbon composite joinery. With aluminum the TPS thickness is almost as bad. With steel however you eliminate half of the TPS coating entirely and the other half goes from half a foot thick to less than an inch thick, a huge reduction in mass. Also, since steel is tougher than aluminum or carbon composites and much easier to handle, you can actually go much thinner with your material and end up with a finished stage that is lighter than anything that can practically be built at that scale using aluminum alloys or CC (this is why Centaur uses steel tanks and gets the most delta V of any upper stage vehicle and why in the 50's we were capable of manufacturing balloon tanks out of steel for the Atlas that let it achieve almost SSTO performance).

All of the highest mass fraction rocket vehicles in history have been made of steel. It's more incredible that nobody really connected the dots like this before and realized they could ditch aluminum and other meme materials for good old steel and get the same or even better performance in many cases.

>>11494123
Of course, it's like asking them to vote on tighter term limits for themselves, no way they say yes.

>>11493885
>I thought minimizing dry weight is everything in spaceflight?
It was early on, till early 80s or so. Ease of manufacturing, cost, and many other factors are also taken into account since then.

question: all explanations for the use of stainless steel over aluminum make aluminum sound literally retarded. Why did it become standard practice in the first place?

>>11494292
It's actually quite decent if you don't care for reentry or reuse. Also muh space age material. It can't handle high heat and develops fatigue cracks easily, but it's not a problem if you throw it away upon reaching orbit, and your only major headache left would be welding it.

>>11494449

>>11494498
It's fairly big, they just don't have a manned part. Their program is a legitimate science/high tech driver in the country, not just a job generator or a national pride thing. They do extremely well in spacecraft engineering. I'd say this is one of the most pragmatic space programs ever.

>>11494512

>>11494522
Yeah. Also their LH cryocoolers with neon ice tanks are literally black magic. Pity they lost Hitomi to such a basic mistake.

>>11493734
>No one has done an “assemble in orbit for BEO” mission

All of the Apollo missions were assembled in orbit, dummy. The lunar module is packed under the command module in the fairing and then flies around to the front of the command module to dock there before heading to the moon.

>>11494660
Other way around. Apollo missions did their burn into lunar insertion, then did the separation and reassembly while underway.

>>11494660
wait, so how was the CSM and S-IVB and LEM packed up in there
it was S-IVB on the bottom making the entire TLI burn, then the fairing with the LEM in it, and then the CSM on top of that?

>>11494694
First & Second stage to get you off the rock and into orbit. Third stage for lunar insertion. Under third stage sat the LM, on top of the LM was the CM.

>>11494698
the S-IVB completed both TLI and parking orbit insertion, the S-IC and S-II didn't have enough ISP to get the whole lunar stack to orbit

>>11494694
>it was S-IVB on the bottom making the entire TLI burn, then the fairing with the LEM in it, and then the CSM on top of that?

Yes. I was a bit wrong, as >>11494684 pointed out.

After the TLI burn was performed, the command module separated from the Saturn V’s upper stage , turned around, and docked to the lunar module, then pulled the lunar module away from the Saturn V’s upper stage. The capture burn is performed by the service module’s engine and the Saturn V’s upper stage simply smashes into the moon or flies off into an orbit of the sun, where they become curiosities to be rediscovered. https://en.m.wikipedia.org/wiki/J002E3

>>11494702
>the S-IVB completed both TLI and parking orbit insertion

No, the Apollo missions performed their capture burn using the service module, and also used the service module’s engine to perform corrections. They disconnected from the Saturn V’s upper stage shortly after the TLI and there’s no way to stick it back together.

>>11491301

JWST has the biggest short of discovering habitable worlds within our local area. I'd rather it not. Also, it's Hubble's successor. So also for that. Many of JWST's delays are a result of technologies that needed to be developed, built, and matured before they could be integrated into the observatory.

The delays weren't unwarranted. They weren't SLS delays where most of the tech already existed, but the cost plus contract basically meant that Boeing could play with its dick for years and not deliver while still extracting payments.

>>11495188
>it's Hubble's successor
Not arguing with the rest, but this is a meme. JWST is a specialized NIR telescope; HST sucks for NIR due to being optimized for visible spectrum and versatility. JWST is propellant-limited as L2 is not stable; HST turns 30 soon.

>>11495223
what are they using for JWST propulsion?

>>11495223

Yes, I know that JWST is a specialized NIR. But the massively increased mirror space is very helpful in gathering a staggering amount of light. Over the last 30 years, also, tech has advanced to determine what an object looks like across other EMR spectrum wavelengths based on IR or UV data.

Additionally, the success of JWST will drive future development of actual true color capture observatories that will truly succeed Hubble. It's a powerful stepping stone, and thereby a successor.

There might be not enough power for SEP, and the spacecraft is complex enough already.

>>11495254

Multiply that by a 100,000 people and yeah, that's about right. Since part of the reason why it costs so much is because the rocket is built across nearly 50 states, then shipped to be assembled and tested preliminary in Texas, then shipped to Florida for actual test maiden flights.

Because making something simpler is just acceptable in space flight. Complexity and high cost is the way to go.

80% of the work that company did was aluminium. Aluminium can be very many things depending on what you mix it with, that's what so nice about it.

Man this is shitty, no specific love for Bigelow but their habs seemed by a stretch the furthest along in development. Don't know why any of these tards are celebrating as if losing one of maybe two up and coming expando-hab makers is somehow a good thing. You faggots want space missions to have to pay a billion a pop for aluminum cans forever?

>>11496033
Bigelow was still around? First news from them in a long time. Put the cart (space station) before the horse (orbital tourism).

>>11496056
>Bigelow was still around?
Bigelow has achieved more then 90% of the private space company's out there who are actually just dummy company's that funnel tax money straight in to politicians and their cronies pockets.
How many private company's do you now that have their own module on the ISS? f
Even if it's a test module, thats still huge.

>>11496060
A very successful test module no less.

>>11494292
Aluminum lets at 660C. Steel melts @ 1400C. Aluminum vehicles cant do reentry landing.

>the galaxy is going to turn out to be very sad and empty

Lol beta pussy. Empty space means space we can fill and make part of our GLORIOUS EMPIRE

>>11495644
Even the Moon is “suitable”.

>>11495964
The starship will allow the construction of rotating stations anyway.

>>11496016

>You faggots want space missions to have to pay a billion a pop for aluminum cans forever?
No, but billion dollar rubber inflatables are just as bad. Okay, so they can expand to three times their stowed volume, so what? They're still expensive as fuck to build.
The future is mass produced STEEL cans launched inside Starship one at a time then joined together in space, and once we have a decently sized rotating space station up, we can use it to manufacture bigger STEEL cans from 100 ton rolls of steel launched by Starships instead of relying on what can fit into a vehicle faring.

>Okay, so they can expand to three times their stowed volume, so what?
they're also more durable and resistant to solar wind and asteroids than steel.

a couple starships converted to space station duties will be more than sufficient for the foreseeable future. Don't even have to do a can-inside-a-can deal; why launch a space station inside of starship

>>11496198
Hell the only two worlds in the solar system that aren't "suitable" are Venus and Io. Venus is Venus, it even lures fags closer with its thin region of (((comfortable))) temperatures and pressures 50 km above hellworld, and Io has too much surface radiation and volcanic activity.

>>11496312
definitely all end-of-life starships should just be made into a giant space station.

>>11496316
Io could be mined remotely, and the same is true of Venus.

>>11496311
Nothing is durable in the face of hyper-velocity impacts, dummy. If you really really want the same or better properties than any Bigelow module, use steel with a layer of plastic on the inside and a layer of foil wiffle shield on the outside.

>>11496325
>Nothing is durable in the face of hyper-velocity impacts
Bigelow modules are basically made out of kevlar which is much MORE durable to impacts than steel. If we use steel for everything, it's for cost, not safety.

>>11496316
It'd be hilarious to see a venus colony pop and fall into hell.

>>11496336
No it’d be horrifying you psycho

>>11496336
Dirigibles don’t pop
Meanwhile your pressurized underground Martian base....

>>11496307
>we
Who the fuck is we, where's your multimillion dollar habitat manufacturing company with hundreds of employees and working prototypes, several of which are currently in orbit and/or attached to the ISS? The difference between you and Bigelow, faggot, is that up until apparently just now he was actually building habitat modules which would have radically reduced the cost and radically increased the functionality of living space in vacuum, while you and I are shitposting on a vietnamese smoke signal forum. A new steel-drum habitat manufacturer hasn't run him out of business, he didn't fold up because mass produced habs pushed him out, assuming the bad feelings of his employees are correct he's just gonna be fucking gone once the quarantine lifts, which by the way will leave Vulcan down two payloads.

>>11496324
It would be extremely hard to do either, for different reasons.
Venus has too much heat to easily work in.
Io has too much radiation, even for machines, to handle for long periods.

>>11496338
Calm down, it was a fucking joke.
>>11496342
True, but I wasn't being serious anyway.

>BREAKING: “Anomaly” at Pacific Spaceport Complex launch rehearsal, no injuries as a result

>The Pacific Spaceport Complex reported an “anomaly” on a launch pad during a rocket launch dress rehearsal on Monday. The anomaly did not result in any injuries, according to Alaska Aerospace CEO Mark Lester.

>Reached shortly after the incident, Lester said “I can confirm we had an anomaly on the launch pad. We are executing our emergency checklist. We request everyone stay clear of the area to allow our crew to address the situation.”

>No details have been released yet as far as what caused the anomaly or how it may affect the upcoming launch.

>At 5 p.m. Lester said the emergency response had concluded. “The area is still hazardous and should be avoided. There will be personnel on site overnight to monitor,” he said.

>California-based rocket startup Astra had scheduled its rocket “One of Three” to launch from the Narrow Cape spaceport as early as Tuesday of this week. Astra has not yet responded to a request for comment.

Maybe Astra should focus less on moving fast and more on trying not to break stuff if they ever want to reach orbit?...

>>11496331
Hypervelocity impacts have enough energy to overcome any chemical bond. The protection you'd get from a thin sheet of lead foil positioned 10 cm from the surface of the hull would be many times more effective than a kevlar wrap with a thickness of many inches.

>>11496365
lotta words to say nothing

>>11496466
Jesus Christ lmao

>>11496466
They’ve now equalled the Falcon 1’s record of 3 launch failures in a row, but without even clearing the pad...

>>11496491
ur a faget

>>11496307
The actual future is producing steel rolls outside the Earth's gravity well from locally mined resources and using those to manufacture whatever the steel cans we want.

>>11496165
Aluminium starts to rapidly lose strength at above like 200 or 250°C. Steel does that as well, but at much higher temperature

>>11496466
Isn't the whole point to develop a fast response rocket that can be assembled and launched on relatively short notice? If they slowed down it would defeat the entire purpose of the competition they're participating in.

>>11496316
Are you forgetting Callisto?

>>11496004
noyce

>>11496824
There's also something to be said for building a functional, non-exploding rocket first and then cutting assembly time and maximizing turnaround. They already missed the competition deadline.
