Will support for Space Explorations be brought back?
This mod has been in testing for a couple of months now, and I think it will be released soon.
It would be great if support for this mod returned.

I haven't kept up to date with their progress, but if it's close to release, I can look into support for it again.

95% sure you can just remove !SE from the info and the mod works in SE 2.0

it seems to run fine for me

The latest release allows installation alongside SE. I don't have the time to play through this to ensure it's working as best as it can, so I'd appreciate feedback and save-files for any specific issues.

So far, I can tell that it does a lot of weird things with the Remote View, so there are some inconveniences. If you aren't using Isolation, then you'll have to double-enter the Sandbox because SE does something that undoes our attempt at entering; if you are using Isolation, then you cannot use the Remote View while inside of the Sandbox. AFAICT, there's not much or nothing that I can do within this mod to work around those, so SE will have to adjust to support this mod.

been working fine for me so far. it doesn't allow rocket pads, delivery cannons or spaceship consoles in the BP world, I assume that is intended.

double tap to get in or single from map view I found. bp world does show up in the planet list on "surfaces" and instantly swaps in and out using that UI

you also can't place train ramps on lab floor. so you need to place terrain first?

I can't seem to be able to place space tiles in the sandbox. Using the tile selector I select space platform scaffold, space platform plating or empty space, and black dirt gets placed instead. Only spaceship floor works correctly, which I assume is because you can normally place it on planets as well.

Trying to paint using the ghost of scaffolding tile also places the black dirt instead:

Yes, Space Exploration automatically converts those tiles because they aren't allowed to be placed like this. I cannot seem to do anything about that.
