🪼FLORIDA SPACE JELLYFISH!🪼 Heads up #Florida! A Space Jellyfish will likely develop as a result of a rocket launch and be visible across the east coast of the state, with the best visibility potentially being near Miami! If you're willing to wake up at 6:30am to see it, you could get views like FSC @GregDieselPhoto did last week! #flwx

NASA and SpaceX are adjusting the launch date for Crew-13 after teams identified an oxidizer leak in Dragon’s propulsion system during standard prelaunch processing. Mission teams are assessing upcoming launch opportunities, and a new target date will be announced once available. Stay tuned for updates. go.nasa.gov/4h08a9d

Swift has been in #space 22 years, studying the universe’s most powerful explosions. Now, it’s falling to Earth. NASA launched LINK to save it, but a failure sent LINK into an uncontrolled spin. Is that the end for #LINK and #Swift? Not quite! earthsky.org/space/swift-spa… 📸 NASA.

⚡️BIG BOLT IN FLORIDA⚡️ Some electricity of the northeast coast of The Sunshine State Friday afternoon - as shower activity has finally returned to a very dry Florida as of late. Rain & storm chances pick up through the weekend - hoping to put a dent in Florida's drought. #FLwx

Happy 44th Anniversary to @weatherchannel, I am just 26 years a part of that! Here's a throwback to my very early days at a small TV station in the Hudson Valley of NY, right out of college.
