We have threads on the X-37 landing. It wasn’t up there sampling pollen.
No, but they didn’t broadcast missions details so speculation is left. I would guess if a threat existed from orbit it has likely been compromised.
The X 37B went back up 3 1/2 weeks ago, 2 months ahead of schedule.
More speculation...It would probably be relatively easy given enough time to compromise what ever orbital threat might exist and make it look like an unknown technical failure which included total loss of communication etc..They'd all get suspicious, but that's all they'd get.
