The ship and the face are different layers right? If not, make it so.
Then you can play around with the brightness/contrast setting to brighten the ship.
To remove the unwanted details from the face, use the quickmask tool. Enter quickmask mode and use a small, well defined brush to manually remove them.
EDIT: You can also use the clone stamp tool.
Here's a nice litte video tutorial that will teach you how to use it: Clone Stamp Tutorial
