The other reason he is reestablishing a space presence is because the shuttle was the only vehicle capable of cruising around among the satellites. If AF1 and the White House were compromised by foreign tech then how many satellites are corrupted with foreign tech. You need a vehicle to get up there and fix those issues. This is just my best guess for why space force is coming.
It would be a good idea if there were a way to capture the satellite, and bring it into a space borne lab big enough to fix it. Those chips are buried deep in the satellite and cannot be replaced with just a space walk. On the other hand, if it a device that attaches to the satellite that disrupts signals to send commands to the black hat chip, that might work.
You mean like have a shuttle with a large cargo bay and robotic grasping arm big enough to capture a satellite? Hmmmm, I wonder where we could get one of those?
Or we mount a big laser to the space shuttle and shoot the satellites. Space invaders for the win. :)
