The idea of using detonation to improve efficiency is quite old. The V1 "buzz bomb" used a pulsejet engine in 1944-1945, and experimental versions of pulsejets using detonations are about as old. The vibrations inherent in pulsejets of any sort have prevented them from being used much.

The basic concept of using continuous detonation waves in some form has probably been around for just as long, but has been more difficult to implement.

Space Karen wants to go to Mars. He does not want the rabble to go to Mars.

Nowadays everybody wanna talk like they got something to say But nothing comes out when they move their lips Just a bunch of gibberish And motherfuckers act like they forgot about RDRE

Wow look at that sucker go

We’re not “all” going. Some will. Sooner rather than later. Setting up a base is going to be decades, but I think we will get there. I’m more certain about the moon and the moon base timeline for obvious reasons.

For that exact purpose I used to have;

a) A tile from Buran (and a propane torch)

b) A Sokol-KV glove

c) A 3kg lump of campo-del-cielo

d) Some JSC-1 lunar regolith simulant

e) some Mars-1 martian regolith simulant

f) A bit of Etna (compare and contrast with the above!)

​

JSC ought to be able to help out with d) / e) - worth dropping them a line.

Laught a this one, i remember what you are probably reffering to. Haha

I know you want to see it up close, but just so you know, most rocket launches are visible from hundreds of miles away. As long as you are in peninsular Florida, you can probably see it when it goes up. I've personally never gotten to see a launch up close, but I've still seen plenty of them from across the state, and while it's probably not AS cool, it's still pretty cool.

He's just Mansa Abu Bakr II re-incarnate. Fucking prometheans will stop at nothing to conquer and leave a wake of decimation. This is the real peen that characterizes so many civilizations that have come before the current iteration.

I always liked the quote about how nasa spent a bunch of money developing a pressurized ink cartridge to have a ball point pen that worked in space. And the Russians just used pencils.

Maybe get one of the fancy space pens. And then some nasa pencils to give the kids?

Those are the same thing if you have the same thrust. More efficient means less fuel mass means more acceleration from a given thrust.

Are you a professional teacher? In the United States? When are you pitching this space stuff to your class? I might have some resources for you.

This past August, my wife and I went on vacation in the Orlando area. While we were there, we checked the NASA website and found that a SpaceX launch was scheduled for that Friday. And we decided to go see it.

We got there before the gates opened. Viewing the launch was included in the admission fee. There’s a bus terminal in the visitor complex that takes you out to the Apollo/Saturn V building; the viewing stands are adjacent to that building.

The launch was impressive and I have a 1:35 video of the launch. Worth every penny we spent.

Now, SLS is built using old Shuttle parts. The Shuttles never seemed to happen on the date and time they were first supposed to go. That’s exactly what happened with Artemis I. So if you’re not living in Florida it’s going to be difficult to see a manned launch since you don’t know if the launch is actually going to happen when NASA says it will.

Okay still important point to make.

Doesn’t the Air Force already have a spy plane that uses this tech?

I didn't say HEU, I said enriched uranium. HALEU is enriched to a U-235 content of 5-20%, natural uranium is only 0.72% U-235.

The fact that ad blockers are even a thing is super upsetting.
