True, they have to factor in satellites and space junk dynamic position besides launch site and upper weather, and in SpaceX/Crew case also weather downrange where booster and possible escape capsule would land. Which is why there are so many delays... anyways, we're past the event but have not been confirmed if we're in the safe of they collided. In the meantime, SN8 wet dress rehearsal is underway, they are attempting to ignite the 3-Raptor pre-burners for the first time tonight. Static fire perhaps this week or next if successful.has to happen eventually tho?
years ago i read about how carefully they have to calculate launches and re-entries to miss all the shit up there, and that was years ago.
