I'm not sure if they have shared details but I assume this leaves a relatively narrow window over the ship that they need to put a satellite, which would be really cool to see more on logistically.
Like how do you move a satellite or satellites to a certain area, at the right time, avoiding other space objects, and then keep them there for 45 minutes during the mission or at least 15 minutes during the blackout zone. I'm sure it takes a huge amount of planning, math, coordination with various entities....
