The drones do not refeul; essentially they are ran by solar power and hydrogen (gotten through both water vapor and liquid). They wouldn't land except when they need repair or need to be hidden, but that would cause another drone to come out and repair them. The whole survey system is entirely automated.
They make for good exprosions because of the hydrogen (which is why they are also entirely automated), too, but they constantly stream video, data, and other information via Subnet. Because of this, Atenisia already has a large knowledge of the planet, the life on it, etc. Such information is open to the public, including the information of your country.
Constant communication with the Sol system continues.
The Atenisian Mason Council knows of another country to the east, but they've scouted such countries' hostilities and decided to avoid any contact.
Expansions on the military are made, however these are partially human reserves and primarily robots. These robots are capable of not only combat, but for many other simulations such as construction and humantarian purposes. Research on a more senstitive AI and "human-like" thinking is being worked on.
