In July, Lockheed Martin completed the build of NASA’s X-59 test aircraft, which is designed to turn sonic booms into mere thumps, in the hope of making overland supersonic flight a possibility. Ground tests and a first test flight are planned for later in the year. NASA aims to have enough data to hand over to US regulators in 2027.

I like the technological idea, but not the idea of catering to the super rich by giving them convenience at the cost of increasing their carbon footprint by another order or magnitude. This is tax money funding toys for the parasitic criminal billionaires.

[–] LetMeEatCake@lemm.ee 25 points 1 year ago* (last edited 1 year ago) (6 children)

Technology filters down. Once upon a time only the rich could afford corrective lenses, but that wasn't a waste of resources. How many of non-wealthy people will read this comment and wear glasses or contacts? I do. BEVs were limited to the wealthy at first too, and now are solidly affordable to much of the middle class: dependent more on their access to charging and their driving requirements than on their budget. The first residential fridges cost more than a brand new Model T when they came out: the inflation adjusted 1922 price was ~$13,000 today. Was inventing fridges worthless?

It's NASA developing new technologies. New stuff starts off more expensive, which means it will start off limited to the wealthy. If you don't want any new tech to come out that starts with rich people being the primary users, then you should go find your local luddite club to join.

There will never be a fuel efficient way to travel at supersonic speeds using combustion technology. This is planet destroying tech. It won't matter in 100 years when everyone is dead. This has no trickle down benefits, nor is it cutting edge. This targets an established market by trying to make it half tolerable for parasitic billionaires to further destroy the world. Supersonic commercial flight was done already. This is 1960's technology with some CAD tools added. Trickle down, it did not. It did however prove exactly the market it is designed to enable. This is a toy for criminals that shouldn't exist; the careless egomaniac destroyers of the World. This is only for the people that are constantly flying and have carbon footprints the size of small countries. It is criminal that this is developed at all right now. It is kind of interesting from an engineering perspective, but we are currently in the biggest deviation in earth's climate since it has been tracked. We stepped over a cliff and have no clue when we'll hit the bottom. The last thing we need is some stupid asshole that chose to make this problem enabled to make it worse.

Aviation is one of the smallest contributions to greenhouse gas emissions as-is: in 2016 it was 1.9% of global emissions.

The danger the rich pose to the planet isn't being first in line for the second generation of supersonic transoceanic flights.

The danger the rich pose to the planet is them keeping coal and natural gas plants open longer because they personally profit from it. It's them keeping their taxes low, reducing our ability to fund renewable energy. It's them fighting tooth and nail against any new energy efficiency regulation (remember the incandescent lightbulb ban fight?) because it "hurts profits." It's them fighting against public transportation.

This? This isn't even in the top 50 of their ills against the climate. The hate for the rich is well placed. Applying that hate to basic science is dangerously misplaced. The rich love when people push-back on funding science efforts.

I see where you're coming from. Battery electric vehicles I think are a good example of trickle-down. It seems the R&D for electric cars affordable to wealthy people leads to new infra and tech for a changing power grid, buses, trains and bicycles.

But two examples you raised:

  • corrective lenses
  • refrigeration

have clear quality-of-life and health benefits. Supersonic passenger flights feel more like a luxury and convenience compared to food preservation.

Hopefully in the development of reduced flight times between other sides of the world we perform research with impact beyond flight. Things like improved materials, fuel, aerodynamics that could be used for trains and trucks. I'm not an engineer but I hope it works like that!

[–] LetMeEatCake@lemm.ee 16 points 1 year ago (1 children)

Faster transportation is quality of life too. Just like cars were, or railroads before them. Yeah, this one is currently worthless for anyone that isn't rich. But if it proves successful it will become useful for more of us. Like you say, there's also just the material and other sciences being done to make it possible that will filter out elsewhere. So much of early space exploration was Cold War dick waving, and now think about how much we rely on satellites. I couldn't navigate anywhere without GPS, personally...

People here take their hate of the rich (which is well placed) and aim it at all the wrong things. Don't like the rich? Tax 'em more. That's what I want. Higher income taxes and even a wealth tax on the top. And way more meaningful inheritance taxes. Instead they're bitching about investments in science.

What an idiotic and short-sighted take. Research on supersonic aerodynamics is useful for far more than just toys for billionaires. Military applications, rocketry and astrophysics, for example. And even regular commercial aviation, because supersonic shockwaves are a major source of drag even at the speeds airliners fly at. Airlines would kill to have a fleet of planes that burn a few percent less fuel.

E: Also, much of the noise an airliner makes during takeoff comes from the sonic booms created by the engine fan blades going supersonic.

[–] SmoothIsFast@citizensgaming.com 26 points 1 year ago (1 children)

How about bitch about the actual wasteful military spending instead of scientific research into physics and understanding the dynamics of sonic booms. Nasa has like .1% of the military budget ffs.

[–] Hadriscus@lemm.ee 16 points 1 year ago* (last edited 1 year ago)

US defense budget was 752.9B for 2022, whereas NASA's was 24.8B

So NASA's funding amounts to 3.29% of the Defense budget (about 1/30)

I agree with you, but it's nice to nail down the numbers

Or it's own people. Which is stupid, because the brain drain will catch up technology wise.

[–] LufyCZ@lemmy.dbzer0.com 10 points 1 year ago

By investing into research of this airplane, the bulk of the costs are going to be manhours.

How is paying engineers going to cause brain drain?

[–] SmoothIsFast@citizensgaming.com 10 points 1 year ago (2 children)

We can tell it's already effecting you by trying to suggest nasa is a waste, when we spend 100 times it's budget on wasted military contracts or the fact we do have a tax bracket that allows someone to even become a billionaire instead of taking back excessive wealth stolen from workers in predatory labor markets. There are other areas we should be getting this money for the public and it sure as hell shouldn't be from aeronautic or space research ffs.

We need bullet trains, not more passenger jets.

Actually just regular passenger trains that have priority over freight trains would be a great step forward

I wonder if research into sonic boom physics could translate over to high speed aerodynamics generally, to include the useful models for high speed trains.

[–] MCk3@lemmy.world 24 points 1 year ago (2 children)

Lack of high speed rail isn’t caused by lack of knowledge about how to do it. High speed rail exists in some places, just not the US.

Instead of more luxury boondoggles for the rich, funded with tax money from people who will never afford it, how about we focus on decarbonizing air travel for the commoners? Fuck supersonic flight, use public money to develop a hydrogen powered regular speed transoceanic airliner so that regular people can have a sustainable long haul air travel option instead of making the carbon footprint of the rich even higher.

[–] Derproid@lemm.ee 13 points 1 year ago (1 children)

Flying used to be a "luxury boondoggle for the rich" same with a lot of things that we view as common today.

A quarter billion dollars to build just a prototype and retread the Concorde fiasco with all its attendant environmental destruction. What does this have to do with exploring space, which is what I thought was NASA's mission?

National Aeronautics and Space Administration

Atmospheric based ~~praise~~ pursuits have always been within their purview. Space just gets all the press.

[–] JohnBrownsDream@hexbear.net 20 points 1 year ago (1 children)

Fair point. It's still striking to me how much public money is being thrown at a project that will benefit just a handful of private citizens.

[–] PowerCrazy@lemmy.ml 16 points 1 year ago

Why is it striking to you that A government funded by billionaires for billionaires is spending public funds on things that will only benefit billionaires?

Whose going to be able to afford this? Air fare is already expensive.

Also, why is NASA doing this with tax dollars?

Is this stupid or am I stupid and missing something obvious?

[–] gammasfor@sh.itjust.works 45 points 1 year ago* (last edited 1 year ago) (1 children)

I'd hate to live in a world where just because something isn't immediately useful it shouldn't be researched.

Being able to demonstrate the ability to suppress a sonic boom would be huge.

People fly first class, people fly businees class. Some have the money.

Also, for some, the time saved is worth much more than what the ticket costs, especially in business (expensive consultants?).

why is NASA doing this with tax dollars

The resulting aircraft/technology can be sold to commercial aviation and/or be used for military purposes

something obvious

NASA stands for National Aeronautics and Space Administration, so it's kinda in scope

I imagine the same was asked when jet planes were first invented, now look at where we are.

NASA is likely doing this with tax dollars because private industry has little reason to push forward research that does not yield an immediate ROI. Not yielding an immediate ROI is a very myopic driver of priorities.

[–] lntl@lemmy.ml 7 points 1 year ago (7 children)

In the west, jet engines were developed to kill fascists and communists. The ROI was good.

I don't see the parallel

[–] zephyreks@programming.dev 7 points 1 year ago (3 children)

Weren't jet engines developed by the Germans to kill the Allies?

This way NASA can get 95% of the way with research/design then they can sell it cheaply to a chosen private sector firm who can make all the money.

Which firm? I'd pay attention to where memebers of Congress are investing

I'm interested to see how this plane performs compared to the Concord. It'll be interesting to find out how bad the maintenance will be.

Also the criticism and the "whatabout other important things" people commenting here should know that more than one type of research can be performed at the same time. This is an aerodynamics problem. The other problems related pollution from engines, fuel sources, and environmental impact are also being worked in parallel. A planet of 8 billion people is able to work on many problems and ideas in parallel without having one be a detriment over another. It's not like an aeronautical engineer can be repurposed to be a fuel chemist!

[–] PaupersSerenade@sh.itjust.works 10 points 1 year ago

Just last month I heard of United's own supersonic plan 'Boom'. Concerning name aside I am interested to read more about the tech behind it.

[–] MattMillz@lemmy.world 9 points 1 year ago* (last edited 1 year ago) (2 children)

But we already had the Concorde.... It stopped flying due to fuel costs and limited flight paths only allowed over oceans, no super sonic flying over land. Hopefully NASA has fixed these issues...

[–] RandomStickman@kbin.social 35 points 1 year ago (2 children)

That's what they're trying to solve, the sonic boom. The spike in the front is supposed to reduce the boom, which hopefully leads to legal supersonic overland travel.

However, time and time again, the market showed that people value the price tag over anything else. The Concorde didn't make it, the A380 isn't looking good. Anything with a high operational cost doesn't seem like it would last, especially with push for greener tech.

[–] deconstruct@lemm.ee 18 points 1 year ago

That's the idea behind the prototype. The sonic booms are lessened so overland flights will be permitted.

[–] autotldr@lemmings.world 6 points 1 year ago

This is the best summary I could come up with:


Editor’s Note: Sign up for Unlocking the World, CNN Travel’s weekly newsletter.

But now, the thought of supersonic travel has been mooted again – by none other than NASA, which reckons that New York-London flight could take as little as 90 minutes in the future.

The space agency has confirmed in a blog post about its “high-speed strategy” that it has recently studied whether commercial flights at up to Mach 4 – over 3,000 miles per hour – could take off in the future.

In the same way, she added, the new studies will “refresh those looks at technology roadmaps and identify additional research needs for a broader high-speed range.”

The next phase will also consider “safety, efficiency, economic and societal considerations,” said Mary Jo Long-Davis, manager of NASA’s Hypersonic Technology Project, adding that “It’s important to innovate responsibly.”

In July, Lockheed Martin completed the build of NASA’s X-59 test aircraft, which is designed to turn sonic booms into mere thumps, in the hope of making overland supersonic flight a possibility.
