@militantangleno I think they kept delaying the launch hoping for the winds would calm. Better weather this week, too many clouds this evening.
Unfortunately launching around 4:00pm
So if you're in California, the reentry of Crew 11's dragon spacecraft should be visible just after 12:30am tonight, look west and it'll appear as a bright, slow moving meteor.
If you're in SoCal you might even hear the sonic boom.
SpaceX is planning a Falcon 9 launch from @SLDelta30, with the launch window opening at 8:36 p.m. tonight, just 18 minutes after local sunset. If it launches on time, it could be a pretty one. 📷🚀🔭
