[Interstellar] Was the Cooper station at the end going to enter the wormhole and proceed to Edmund's planet?

Since Plan A supposedly was a go no that Cooper encoded the mising data for the equation that must mean the ultimate goal of populating one of the 3 planets was going to happen. So, are the inhabitants of Cooper station going to Edmund's planet to join up with Amelia, who also enacted Plan B?

Is the worm hole even still open? If there's no plan of going to the new planet then why even build a space station? Couldn't they just build a bunch of giant domes on Earth and re-create the utopia-like climate that we see on Cooper station? Isn't space MUCH more inhabitable than the current Earth we see?

They were going to Edmund's planet. Murphy knew that Amelia was successfully enacting Plan B, which means that they knew on earth that the planet was inhabitable. It took several decades to get the station running and off the ground, but that makes sense given the time dilation; Amelia is, after all, only just starting to set up camp on Edmund's planet by the end.

The only reason Cooper Station is near Saturn (that's where Cooper was found floating after passing through the black hole) is so it can go through the wormhole to Edmund's planet. Remember that those planets are outside of our galaxy - the only way for humanity to get to them is through the wormhole.
