Satellites would definitely be a great part of a space update! I would definitely be interested in invading other space stations.
add-on to space update: spaceships! (satelites ((frick cant spell it)) are used for radar. spaceships carry humans and animals). You can make using 4 thrusters, 4 flywheels, a bunch of copper wire, titanium, and depending upon the kind of spaceship, fuel/solar panels.
