Why not hydrogen instead of helium? It's much cheaper and lighter.

If I recall rightly, hydrogen leaks out of the balloon so fast because of the change in pressure at high altitudes. Not a problem at lower ones, but way up I seem to recall that it is.

Funny because helium leaks out faster than hydrogen under regular conditions, being smaller in practice.

We need a cheaper way to down these spy balloons. The sidewinder missile + F-22 flight time costs are an order of magnitude greater than the total cost of launching one balloon. Send over the High Energy Laser with Integrated Optical-dazzler (HELIOS) to protect the west coast.

The balloon shot down last week was likely order of magnitude more expensive than the Sidewinder that shot it down. Someone posted link to similar sized NASA balloon that cost $1 million for just the balloon and maybe platform but not the payload. It might be possible to shoot down balloons with unguided rockets. It depends on how close the fighter can get and how accurate the rockets are. Rockets are super cheap.

Yeah, but that’s a NASA balloon which adds one or more “0” to the price tag just so it can source components from, and support jobs in, all 50 states. (Ok, being sarcastic, but I’m curious on the actual cost.)

> How much does a weather baloon cost? ...compared to a F22 flight, a missle + all the logistics? If this is an actual spy object you also need to factor in the cost of the surveillance. How much money does the military lose due to the sensitive information being lost. Or how much does the military need to spend to regain strategic advantage? That probably costs more than a F22 flight and a missile. Obviously this de…

> How much money does the military lose due to the sensitive information being lost. ...probably around zero dollars. It would be different if it was above say active war zone but in this case it is almost as far from potential warzone as possible so probably absolutely nothing.

Julian Assange's argument is that the loss is negative. Revealing secrets obviates the need to pay for secrecy.

I'd rather my own government spy on me than China. I'd rather Hannibal fucking Lecter be able to see me through my webcam than China.

Your own government has a much higher ability to affect your life than China does, so what you're saying is completely irrational. Not that it's OK for the Chinese to spy on us, mind you, or to claim that they don't have nefarious purposes.

I was going to agree with your comment ... then wondered why I would even entertain "which country would I rather be spied upon by."

Given the Chinese have been complaining to the UN for the last year about American Low Earth Orbit satellites spying on them (Starshield, Space Development Agency, etc..) this balloon thing is pretty clever.

I don't see an equivalency. Low Earth Orbit satellites are above the ionosphere, balloons below. I suspect if it is radio traffic that you are interested in listening in on then one of those is much more effective.

The helium is generally the biggest cost for a launch. You generally need welding grade helium instead of the party balloon variety which costs more. The price fluctuates a lot because of some complicated economics related to natural gas production, but getting that high can easily set you back $400.

Why not hydrogen instead of helium? It's much cheaper and lighter.

Methane has a decent amount of lift, it's relatively cheap, and it stays in the envelope.

In Australia we use hydrogen in our weather balloons. It’s essentially a safety/cost trade-off.

I feel sorry for the pool soul who decided to send up their DIY weather balloon with gopro to get that space shot. Who knows he might even have a video of a F-22 sending a missile over.

How much does a weather baloon cost? ...compared to a F22 flight, a missle + all the logistics? If it's cheap enough, there will probably be youtubers and tiktokers buying them en-masse just "for the lulz".

This guy launches lots of balloons with homemade taking beacons.

I think anyone sending stuff into the sky with a go-pro has to be reconciled that the chance of loss is pretty high. And if they got footage of the F-22, it's probably worth a lot more than their go-pro.

Each one of those sidewinder rockets is half a million dollars.

Think about how much healthcare, food, housing, we are burning up with this nonsense.
