SpaceX's Starship V3 megarocket finally has a debut launch date. Here's when it will fly

You'll be able to watch it live here at Space.com when the time comes. Another view of the May 11 launch rehearsal.

And each fin is now 50% larger and significantly stronger, according to SpaceX. "These fins include a new catch point and have been re-clocked on the booster to support vehicle lift and catch operations," the company wrote in an update today . "They have also been lowered to reduce heat exposure from Starship’s engines during hot-staging." SpaceX made many other modifications to Super Heavy as well. …
