That's the only thing I know. We've got to lobotomize them first before we put them in. You know when you run water in a faucet and it makes this and then there's that ring? That's like the heliopause, where it goes from supersonic to subsonic. So our heliopause is doing that in the interstellar medium, but here's the thing.

There was a previous satellite, so the guy who's running his professor out of Princeton named Dave McComas, okay? So I don't know if you remember the Ulysses satellite that went over the pole to the sun.

Went over the poles of the sun, and we got to see that the solar wind around the mid-latitudes, you have the regular wind, 400 kilometers per second. Out of the poles, the high-speed wind, 800 kilometers per second. Didn't know that. So young Dave McComas is the guy who made that famous plot. All right? Okay. So then he had an idea, and the idea is crazy.

Let's look at neutral atoms coming toward Earth from outer space. Who looks at neutral atoms? We look at photons. We look at different hydrogen particles.

But here's their origin. these electrons from the sun go out, they hit the heliopause, so there's magnetic fields there, there's ions trapped in those magnetic fields, those electrons get captured by those ions, and they become neutral.

No. Anyway, while the ion is ionized, it is tied to the magnetic field and it's stuck out there. But once it becomes neutral, it is no longer stuck. It's no longer tied to the magnetic field. Because it has no charge. Because it has no charge. So some of them stream into the inner solar system. So you can get a map of the stuff that is in the magnetic field.

Raining back down. And they discovered that if you look at the galactic magnetic field, It wraps around our bubble, and perpendicular to that is a, just like we have a radiation belt around our planet, there is a belt around our heliopause. And so NASA goes, that's interesting. Now let's do a satellite that will look at that in way more detail.

Just the unknown. It's the exact same thing. You're going to find something you've never seen before, just like they did with Ibex. So now they're looking at acceleration from the sun. They're looking at acceleration in those magnetic fields. And they're testing the interstellar medium and what it's made of because those particles also stream in.

So that's why it's the interstellar mapping and acceleration probe.
