What aerodynamic effects would we see that we wouldn't see on Horizons planets? I genuinely think the entry will be identical to Horizons except for some potential additional heat graphics effect. They won't have changed the flight model.
Atmo re-entry effects and challenges in Odyssey?

Wind and the effect it can have on your flight vector. Depending on the wind force and your vector calculated air resistance and the strength of your directional thrusters wind may push you to one side or another. But as I said above, tenuous atmospheres simply don't produce enough force to be relevant for that in most circumstances.
Oh, and breaking the sound barrier may be a thing. They definitely need to add that.
The sound barrier on a planet is dependent on its speed of sound, while the audio "heard" depends on atmos pressure.

Are you serious?
I hope that is a joke or trolling
Tell that to Perseverance
By my calculations Perserverance was travelling at Mach 16 when it entered Mars atmosphere. That’s some parachute.
No, in a tenuous atmosphere I'm not sure it would be that much different than landing on the horizons planets in our spaceships with seemingly massive gravity defying engines. I suspect that's what we're going to get in EDO regardless.
If we get heavier atmospheres and earth-likes, gas giants etc, then it makes perfect sense for them to code complex atmospheric turbulence etc.
In a previous comment that seems to have disappeared, I mentioned that Perseverance entered the Mars atmosphere at 20,000km/h (5555m/s) while our ships can fly a max-speed of ~900m/s. A dramatically slower velocity.
Meanwhile. Supercruise (and glide) is a warp-bubble.
That opening planet doesn't look too much like a "blue tint".
Well, I hope I'm wrong.
I hope Odyssey is just the foundation to fleshing out more landable planets, more legs gameplay, and that sort of thing. While it's not ideal, I think it's an adequate excuse that these are tenuous atmospheres, but in the future I expect to see them with denser atmospheres.
I think the reason why they've stuck to tenuous atmospheres at first is just because of things like re-entry, atmospheric flight, and weather effects. My view would be that later on if/when an atmospheric flight model is added, you blend it (per ship) anywhere between a super dense atmosphere all the way up to none (space & the model right now), so it's adaptable to any atmosphere condition added in the future and retroactively. This same logic can be applied to how intense any re-entry effect would be, too.

Oh yes it would be since there is a presence of a medium that will cause drag/friction on certain speeds same as you said there will be some heat effect...if there is any amount of heat effect than mulitply that by xx that will cause significant change in FM (aerodynamic penalties) at those speeds.
It is some very basic physics and aerodynamics and i don't need to explain it here.
There simply needs to be new FM if they want it to be at least somewhat realistic.
For example you comparing it to a Horizons and vacuum means NASA sent that tiny chopper on Mars for nothing.
You can also make comparision ratio for example ED ship speeds on Mars with GA or ww2 aircrafts speeds on Earth.
I think when they do atmospheric worlds (where they really NEED to do things like weather) that technology will feed back to the tenuous atmos worlds in the same way the new landscape tech is feeding back to the Horizons worlds.
Dr Kay Ross said in the stream that they wanted to redo the planet tech so they can have a brand new foundation for Odyssey AND FOR WHAT'S TO COME, without having to redo it again. So yeah, I guess we will see more in future updates
Gliding in at 2500mps appears to be normal flight.. Are you certain about that. ?

No, one is real and the other is a game.
Flight model changes would make sense if fdev had said to us that we were getting clouds and simulating winds etc. Instead they said months ago that because it's thin atmospheres, we wont be getting "aggressive" weather, storms etc.
It would be good to have the flight model changed in atmosphere, I'm just saying I can't see it.
Glide phase seems to be a weird hybrid of warp bubble and normal space flight, the physics there are murky.
There was a thread that got pretty deep into the physics/aerodynamics weeds back when the "tenuous atmospheres" bit was announced, have to see if I can find it again. I think the conclusion was that there should be some reentry effects at 2.5 km/s, but honestly not much. Even in Earth's atmosphere most of the heating is over by the time you're that slow. So it would be anticlimactic but physically plausible if they didn't put any effects in.
In terms of flight, at a few hundred m/s a large parachute produces a respectable drag force on Mars, so it's reasonable to think that our ships would at least notice the air. Actual aerodynamic flight would need much larger wings than even the Beluga is sporting though.
Hard to tell, this was said about Beagle 2:
30 times the speed sound is just about 10 kilometers a sec.
Our ships enter with a quarter of that speed.
Drag resistance rises/drops progressively as the projected surface of a space ship is a squared factor. So at a quarter of the speed, there might be a measurable rise in temperature, but if it will be noticeable...
