What would atmospheric entry look like?

This thread is an interesting read.

That gif in the OP is quite dramatic. I think the ships we currently have would be able to handle an atmospheric reentry relatively well :

- The amount of fuel we carry on board allows us to actively slow the ship down, while current reentry technology usually relies on friction and trajectory management to slow the ship. We have so much delta-V on tap, we can probably burn retrograde (or use the retro thrusters) for hours without running out.

- Our ships are able to approach quite close to stars, and sustain the heat for a few seconds even when approaching too close, thanks to our active radiators. Currently shields don't do anything for that, the hull materials and the radiators do everything.
So reentry temperatures of 3000 Kelvins for an Earth-like should be manageable, especially with the help of our thrusters, minimizing the amount of time enduring that level of heat.

- In atmosphere flight would also be fine, since we can already fly around planets with several Gs of gravity just fine. The presence of air would probably make the ships more sluggish, but nothing major.

For these reasons, I think the glide and approach mechanic currently ingame would work fine. I like the idea of having to follow an ideal trajectory, or maintaining a specific angle of attack to avoid overheating.


edit : due to real life events, it took me ~ 45min to post this, so everything is ninja'd multiple times

Pretty much all there is to it ^ Hopefully FD will add some drama to it for gameplay reasons, although completely unnecessary considering the capabilities of our ships.
 
I wonder what kind of boom a ship suddenly appearing from a supercruise glide will produce. Should be a different one depending on atmosphere density and composition.
 
And when we're in glide what is slowing the ship downdown, we're in hard vacuum or barely trace atmospheres at the moment in an unpowered descent?

Which is why I believe the "glide" was invented with atmospheric landings in mind, but has been adopted for airless planets also. It was a long long time ago that we first had planetary landings, and for whatever reasons, it seems that atmospheric landings have been considerably delayed. The "glide" suggests that to me, at least.
 
I imagine it will be much like the mechanic we already have. The addition of a correct glide path would be great with damage when straying off it.

Interesting take on glide mechanics. Hadn’t considered it... but yes, it makes sense.
 
Since ships in Elite have the thrust that they could enter an atmosphere at a low speed where shock heating is not an issue.

They can hover so don't need forward momentum to generate lift so have no minimum forward speed.

Ignoring what ever protects them from Stars when fuel scooping.
I would imagine for expediency for the player, a similar "Glide" will faciliate a quick reentry, and the Planetary Approach Suite will have an Upgrade for Atomsphereic entry.


I'd imagine the first Atmospheric flight won't be landing on planets but flying in the upper atmospheres of gas giants

Not really, glide was put it as technical requirement - game terrain engine needs throttling/approach vector & speed limiting to avoid visible mesh & texture popping.
Ship must me kept with certain trajectory and speed so terrain engine able to catchup with terrain generation (which happens continuously as you fly).
E.g. it wouldn't be able to keep up with certain approaches (e.g. vertical landing from orbit). Hence the enforced "glide trajectory".
 
I saw a neat clip of an anaconda (edit) corvette entering a planet'ss atmosphere and wondered, what would that look like in Elite: Dangerous? What would be the mechanics in game?


Well, we couldn't orbital glide inside the atmosphere. I suspect that would cause havoc with the planets weather system, among other disturbances.

Perhaps we would orbital glide to just above the atmosphere reentry point. One hundred kilometers sounds about right. The space shuttle used to reenter the earth's atmosphere at 28,157.5 (17,500 mph; mach 22). Even though it's 3304, I don't think any spacecraft in the Elite: Dangerous universe can withstand that about of stress and friction on the hull.

Remember Thor's ship when it got overrun by the replicators on "Stargate SG1"? Thor told them that the ship needed the shields to renter the atmosphere or it would breakup like anything else. The shields in Elite: Dangerous would buckle under that much heat energy, and the ship would fry itself.

Let's say the ship enters the atmosphere at 1200 m/s. It could glide down to 10k altitude. That would take 75 seconds. The shields can withstand those stresses, but you have to navigate a corridor of least resistance to minimize the stress on the spacecraft. Remember "Aliens 2"? If you leave the corridor the ship might suffer serious structural damage, and if you're small enough, disintegrate; no more ship. And oh yeah, you have to have your shields modified for atmospheric landings to withstand the heat.

Yes, I know I watch too many movies and SciFy shows, but I think this idea might be a neat mechanic. What do you think?

Stargate ships kick asp over anything we have in elite dangerous. Lol. 1 single puddle jumper could take down a capital ship.

From my understanding, the glide is the ship gliding on the FSD wake, as soon as the wake goes, you are not bending space so it looks like you are slowing down. You are actually not though it's just that you are not warping space and time around you anymore. I would like to see the glide mecahanic be used for coming out of supercruise at rings and space stations/outposts too.
 
To be fair, ships have very good cooling systems, to be able to dissipate many MW of heat :)
Just turn your broken canopy away from the star, you'd be fine (with only minor radiation sickness/sunburn which probably easy cure by future medicine ;) )

Yep, which is why a 32T life support system that only needs to supply oxygen to 1 (or if you care about your NPC, 2 people) runs out of oxygen in 7m30s, perhaps.

I think the reasoning behind the huge life support systems is that it supplies life support for the entire ship, even though there's only one person on the ship.

But how you get oxygen from iron and nickel is beyond me.

+Rep

That vid you found is sooo cool.

I think a glide like the Space Shuttle would be fine.

Maybe you would need to purchase Atmospheric Shield Upgrades, or Atmospheric Hull Mods, or both?

You get oxygen from iron oxide which you can get from iron ore.

The life support module is actually a cage for a goblin with alchemic powers. You give him shinies and he makes them into air.
