Punctuation for a fictional spacewalk scene.

Here's a chunk of dialogue (it's still rather rough, I plan to go through all of it with a fine-toothed comb to make sure it's clear who's saying what from where), just to give you guys some idea of what I'm trying to write here. HOPEFULLY it makes sense lol. Thanks in advance for any input!

In this case the perspective belongs to Evans (from inside his helmet during a spacewalk), Denisova is his partner on the spacewalk, and Flight/Shane Douglas is the pilot inside the spaceship (unseen during this scene, only heard over the radio).

Wow...I'm confusing myself just trying to lay it all out. Maybe I should quit scifi after this. :p

Dialogue Segment:

“Denisova, you reading me over there?” Evans asked.
His spacewalking counterpart waved again, then tapped her helmet with a thick-gloved finger. Communication trouble?
“Flight, Evans. Looks like I can’t reach Denisova. Are you getting her signal inside?”
‘Uh, okay. One sec...’ Shane Douglas’ voice came through clear and strong inside Evans’ helmet, evidence that the problem wasn’t on his end.
‘Denisova, Flight. You having trouble with your com?’
“Affirmative Flight. I’m hearing you okay, but I can’t get through to Evans, and I’m not hearing him either.”
Evans thought that it must be some sort of vaccum interference related to the anomaly. It was the only guess he could come up with, given the fact that they had a clear line of sight and weren’t far enough away for distance to factor in.
He relayed his assumption to the pilot. “Something to do with the anomaly, maybe?”
‘Could be, Evans,’ Shane replied. ‘If so, nothing we can do about it from here. You’ll just have to play phone tag. I’ll keep an open channel and relay any necessary communications.’
Necessary. No idle chatter. Which was fine with Evans. He thought with amusement that his chatty shipmate might not be able to contain herself, though.
He heard Denisova’s conformation, then added his own. “Understood,” Evans reported, then he shifted his attention to the deployment.
‘Denisova, Flight. Swing around and take a look at your outward control, make sure the buffers are diverting the shear. Your numbers are a little weaker than what Evans is showing.’
“Roger Flight. Coming around.”

DaveinJapan I am DaleinUSA. Apparently you're a newcomer so some if not many of us also interested in such nonsense might like to learn more about you, as with my recent msg to Jes

Too many italics can be a bit much. Maybe try italics only for Douglas. Otherwise, it's basically a conversation once you forget the electronics part of it.

You can also help to differentiate between the speakers by adding more descriptive prose. E. g. he heard static, she was breaking up, there was a slight lag from Flight Control, that sort of thing.

Good advice Jespah - thank you!
