Eve flyby, science in the atmosphere

[xcorps]

What's a safe periapsis to do a flyby for Eve? I'd like to get some atmosphere science along with all the rest, but I don't want to have an unplanned rapid negative acceleration event.

I'm probably going to fly through from a landing on Gilly (at least I hope to land on Gilly).

At almost any speed, EVE above 85km will have you in atmosphere, but negligible aerobraking.

About 75km is needed to go from a Gilly-Eve orbit to low eve orbit.

About 63km is needed to go from interplanetary speed to low eve orbit.

About 58km is needed to go from interplanetary to direct landing.

Note though that you won't get atmospheric science unless you're in a suborbital trajectory, from what I remember.

Yeah, I didn't get the atmosphere scan. Maybe next time.

Yea... so you've got to aerobrake to the point that you lose your perapsis, do your science real quick, and then fire rockets to get a perapsis above the atmosphere again and get out of that hellhole that is Eve.

Its still a lot easier than an eve ascent from the surface

Yeah, I'd need a bigger boat. I had 4 nukes and 4 LV45 with like .18 Dv for that flyby. (I was keeping the LV45's for the transit burn back to Kerbin, only a few hundred Dv).

Yes these. It's not good enough to just get your AP and PE inside the atmosphere, but your PE must be no kidding sub orbital.

Yep, won't work. I tried this over Duna, but only got science data from "space near Duna", even at 10km.
