SpaceX was planning to launch the Falcon9 rocket from Kennedy Space Center this evening, but those plans were scrubbed when a stubborn thunderstorm parked itself between the launch pad and I-95 on Florida’s Space Coast.

According to the flight rules followed by all that launch here, lightning cannot strike within a 10 mile radius within 30 minutes of scheduled launch time. Launch time was scheduled for 5:55pm ET.

Due to today’s scrub, the launch has been rescheduled to 5:07pm on Saturday. However, there may be even more thunderstorms and rain showers then; the 45th Weather Squadron which provides weather forecasts for launches in Florida, said that while there was a 30%  chance weather would interfere today, the odds grow to 40% on Saturday.
