Weather is presently estimated at only 40% favourable for launch, and Elon Musk has said that weather in the first stage booster recovery zone is estimated as permitting around a 60% chance of successful recovery, so this one may be delayed.
A second Starlink launch is scheduled for Wednesday, 2021-02-17 at 05:55 UTC.
