If there’s one thing that’s a certainty here on the Space Coast, it’s that launch schedules can and do change often. After last night’s delay of the planned launch of Falcon Heavy for the US Space Force, SpaceX stated that the next attempt would be no earlier than tonight, Tuesday December 12th. That has now been changed to NET Wednesday, according Space Launch Delta 45 of the US Space Force and SpaceX.

“Now targeting no earlier than Wednesday, December 13 for Falcon Heavy to launch USSF-52,” said the company in a post on the X platform at 12:54 PM today. “The extra time allows teams to complete system checkouts ahead of liftoff.”

Weather may turn into a major factor as well. USSF 45 Weather Squadron’s latest forecast for the launch — issued at 9:30PM Eastern Standard Time last night — calls for a 60% chance of unacceptable conditions come launch time tomorrow.

While it is not an official forecast by the 45th Weather Squadron, conditions Thursday and Friday are expected to have high winds, followed by two days of a 75% chance or greater of rain over the weekend. As if that was not enough, Saturday has a high chance of thunderstorms as well. All in all, those do not look like good days to go to space.

Tonight, however, the weather does look favorable for a rocket launch. The 45th has forecast a 65% chance of favorable conditions during SpaceX’s planned Starlink 6-34 Falcon 9 launch from pad SLC-40 at Cape Canaveral Space Force Station. That launch window extends from 11:02 PM until 2:58 AM Eastern Standard Time on Wednesday, December 13.
