I second the wording change. Having to launch new missions for each stage of the construction phase is OK for the mun/minmus but wouldn't scale well outside the Kerbin system. Setting up a base on Laythe would take 2-3 years for the scan contract (launch window + travel time), another 2-3 years for the rover, another 2-3 years for the habitat... Better to just be able to send one mission with a scanner, rover, habitat, crew, etc in one go and land them down one after another.
