Casually walking up to an object with *visible* gravitational lensing. What could go wrong?

A fusion rocket based on discussion with Isaac Kuo on Mastadon.
The pulsed MTF thruster is mounted on a canfield joint, which provides both spingrav and propulsion.
The habitat module is buried inside a large propellant tank at the opposite end to maximize shielding

Another possibility for fusion drive appearance, based on this projectrho.com/public_html/...
The optically thin plasma is outshone by the incandescent tungsten of the engine nozzle
(still trying to figure out how long a visible plume would be)

Yes, I'm assuming some form of afterburner, which I know could technically use all sorts of things, but most likely (and to make the question simpler) would use hydrogen or water

Subsapient has pointed out my error. The hot plasma is still emitting visible light, it's just outweighed by the non-visible emissions (which matches the EuroFusion link when I re-read it)
So definitely a bright light in the nozzle, and probably at least some glowing plume like other plasma rockets

I think you're right. I reread the EuroFusion link, they don't say the hottest part isn't emitting, just that there's less light, and the cameras are having to deal with a huge dynamic range. So I think you're right, there's a light inside the nozzle, and probably at least some visible plume too

Wait, I'm re-reading the link euro-fusion.org/FAQ/where-do...

Even though the hottest part of the plasma in the tokamaks isn't emitting anything visible?
If you're right, then that would at least mean a bright light inside the nozzle, though I don't know about the visibility of the plume.

We could still justify that for the ISVs from Avatar, which I'm pretty sure are afterburning pion rockets, by saying that some of the antimatter is still reacting in the plume rather than the nozzle (though that has terrible implications for the unshielded craft right next to the plume)

Probably yes, but in this case I'm concerned with what a regular human eye can see

In that case the visual cue of a drive turning on would be the increase in glow from the radiators

Interesting possibility raised over on Mastadon:
Maybe nothing visible at all. No plume, and nothing inside the nozzle.
Inside the nozzle, the bremsstrahlung radiation is x-rays, and the hot plasma is invisible.
It's only when it cools that it glows, but by then it's too dispersed for our eyes.

@nyrath.bsky.social @toughsf.bsky.social @scottmanley.bsky.social or anyone who might have any insight, I am trying to figure out what the exhaust plume of a Fusion Rocket in vacuum might look like.

Didn't know it was intended as a jab. For goofiness, maybe more chibi proportions like Periapsis: Eclipse is doing?

I do think the names are maybe not a great fit for the UNSC, but on the other hand I really like the names themselves.
"In Amber Clad," "Forward Unto Dawn," and "Pillar of Autumn" are gorgeous

Could've gone with an air cushion like the De Havilland XC-8A. Then it could touch down on land too, and probably have less drag while cruising

The Direct Fusion Drive also doesn't have tapered radiators. They seem to treat the body of the engine as fully shielded, though I don't know about the exhaust plume
