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.

america will do anything but invest in public transport huh

[–] SmoothIsFast@citizensgaming.com 18 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 8 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

[–] twogems@lemm.ee 10 points 1 year ago (2 children)

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

[–] SmoothIsFast@citizensgaming.com 8 points 1 year ago (1 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.

[–] strawberry@artemis.camp 3 points 1 year ago

that's actually a very good point

[–] LufyCZ@lemmy.dbzer0.com 8 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?

We need bullet trains, not more passenger jets.

[–] library_napper@monyet.cc 9 points 1 year ago (2 children)

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

[–] Stuka@lemmy.ml 4 points 1 year ago* (last edited 1 year ago) (3 children)

You don't want that unless you want the cost of virtually everything to increase.

Don't fuck with the infrastructure that keeps every corner of a country running on a day to day basis.

[–] library_napper@monyet.cc 3 points 1 year ago

Sounds like you've never participated in civil disobedience. Shame.

[–] PowerCrazy@lemmy.ml 3 points 1 year ago (1 children)

The railroads should be nationalized and new ones built over highways.

[–] Stuka@lemmy.ml 2 points 1 year ago (1 children)

Ok, come back when you aren't living in a fantasy land.

[–] Anticorp@lemmy.ml 2 points 1 year ago

It's amazing how out of touch with reality so many people on this platform are. It honestly feels like there are a lot more kids on Lemmy than there were on Reddit. They're smart kids, but kids lack real world experience, and it shows.

Well you still need to figure out the sonic boom too, ffs you anti science people are fucking morons.

[–] AnAngryAlpaca@feddit.de 3 points 1 year ago (1 children)

Price per km of track goes up exponentialy the faster you want to go, which means they will either have expensive tickets or will be unprofitable.

[–] Kavorka@lemmy.ml 9 points 1 year ago (1 children)

The rail network should be a service not a for profit organisation

[–] AnAngryAlpaca@feddit.de 2 points 1 year ago (3 children)

Still, someone has to finance it. In the worst case you have a high speed rail network with high operationg costs that nobody uses, but taxpayers still need to maintain.

[–] NattyNatty2x4 7 points 1 year ago

I swear if firefighting wasn't currently publicly funded, you'd argue against making it publicly funded because it might not be profitable

[–] max@feddit.nl 4 points 1 year ago

If it’s there (and not terrible), people will use it. Will it break even on the costs? Maybe. Maybe not. Still worth it, however.

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?

[–] LufyCZ@lemmy.dbzer0.com 18 points 1 year ago (5 children)

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

[–] _MusicJunkie 3 points 1 year ago (3 children)

Concorde wasn't profitable in the long run. Nowadays with video conferencing, even less people need to show up to a transatlantic business meeting.

Unlikely this makes financial sense.

[–] SmoothIsFast@citizensgaming.com 4 points 1 year ago (2 children)

Great it's cool research though and should continue, if you want to bitch about wasted taxes go comment on military threads and comment there where billions are wasted on shit contracts that never materialize due to incompetent base mangers who can't distinguish vapor ware proposals from real tech. Don't bitch about scientific research that's just fucking dumb.

[–] Gargleblaster@kbin.social 3 points 1 year ago (1 children)

A commercial passenger plane should not be the subject of government research.

The science behind minimizing a sonic boom is not just applicable to commercial planes, ffs stop trying to kill science and research fucking idoits.

[–] _MusicJunkie 2 points 1 year ago

Chill mate I'm not even from the US. There still is no practical use for this.

That is what companies like Boeing and Lockheed are for.

NASA has no business making airplanes for rich passengers.

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 5 points 1 year ago (2 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 4 points 1 year ago (2 children)

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

[–] Revan343@lemmy.ca 2 points 1 year ago

They were in development in various countries simultaneously, Spain would have likely gotten there first if not for Franco. Germany did manage the first jet fighter and bomber though, with Britain not long after

Are you claiming that the idea of the jet engine, prototyping, and finalization of the jet engine was entirely sparked by what you're referring to? I would argue that there's a long line of research leading up to what you're referring to that would've resulted in the questions you're asking.

[–] lntl@lemmy.ml 2 points 1 year ago (1 children)

Yes, I am. Although the concept of a jet engine was known about for a long time it was only prototyped and finalized for the war effort. Since the Germans knew they were going to war first, they had a head start and finished first.

Everyone else launched reactionary programs. The goal of America's program was to kill fascists, but they didn't finish before the war's end. Afterwards they pivoted to communists.

[–] papertowels@lemmy.one 2 points 1 year ago (3 children)

And what of the folks who developed the concept of a jet engine?

We definitely can't afford this.

Thus will only further drive the climate catastrophe

[–] zephyreks@programming.dev 2 points 1 year ago

This is the only way to remain competitive when the US' largest rivals are able to tap state funding for research.

You don't see the military applications of large-scale supersonic flight?

[–] dishpanman@lemmy.ca 9 points 1 year ago

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!

[–] Disgusted_Tadpole@lemmy.ml 9 points 1 year ago

Wait, I’ve seen this one

[–] Scrof@sopuli.xyz 6 points 1 year ago

Just call FFS, we don't need this.

[–] autotldr@lemmings.world 4 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.

JFC, can we have a carbon tax already?
