Odyssey and airless water worlds?

I wonder if such planets will be landable especially if some water plantes feature very small islands like this one

I'm not an astrophysicist (nor did I stay at a Holiday Inn Express last night), but is it even possible for a liquid water world to NOT have an atmosphere? Water evaporates into its constituent hydrogen and oxygen. Wouldn't that effectively guarantee at least SOME atmosphere?

I have a feeling this is one of those questions where I'm going to wish later I had spend 2 minutes Googling before posting ...
 
Yeah this is just another one of those nonsense planets that the Stellar Forge generates from time to time. Regardless, it seems highly unlikely that we'll be landing on any planets which aren't functionally the same as the planets we already land on + different skybox. I don't think there are going to be lakes or pools of liquid, and Frontier has already stated that the terrain tech is basically the same as it always was; ie just heightmaps with no undercuts or caves or anything like that.

It wouldn't break down into hydrogen and oxygen but it would seem likely to evaporate (water vapour, "steam").

So you're right but unlike the others I think the right conditions could exist where you might have a proto atmosphere, water vapour and nothing else. The temp in the OP is 100 below freezing but water might still be liquid because the surface pressure is virtually zero but the gravity is pretty high. So the gas produced might not get blown off ... I think it might always be snowing/raining though as the gas escapes but is pulled back down again .. almost a liquid/slushy atmosphere or surface?

it's possible for really cold planets to have a liquid ocean under a frozen surface leaving no atmosphere, but unlikely. They'd be classified as a water planet though.

There are lots of things the stellar forge creates that dont make sense and airless water worlds aren't even the top 10. It seems unlikely that odyssey will allow landing on anything with liquid anything since it seems like they're not prepared for dealing with how ships/vehicles/players would interact with liquids of any kind.

Think of the most boring planets with a bit of atmosphere and that's what you'll be able to walk on. You'll be waiting a long-long time for any "active" planets.
