YOu should see the group o ships waiting around the empty area it used to be in.
I'm one of them.
After doing extensive research, and having undergone at least one beta class temporal shift, the Sulu Detection Agency has discovered that the apparently missing K7 Deep Space Station is in fact being cloaked by a stolen Romulan cloaking device.
Details are still being investigated, but it seems that WIldman owed Commander Sulu a favor, and the ever elusive Commander chose this opportunity to leave an android double of himself at Earth Space Dock, and conduct experiments with the Romulan cloak on K7.
More details will be revealed as the Agency makes progress.
