As Florida braces for a hurricane expected to make landfall this weekend, the U.S. Air Force and SpaceX still hope to launch the X-37B reusable spaceplane before the storm hits.

However, officials in Cape Canaveral, Florida, are forecasting only a 50 percent chance of acceptable weather for Thursday’s launch, which is expected to occur sometime between 9:00 a.m. and 3 p.m. Eastern.

Friday’s forecast is worse, with only a 40 percent chance of acceptable weather.

But with Hurricane Irma expected to reach central Florida on Sunday, it looks like Thursday and Friday offer X-37B’s best chance to lift off from Kennedy Space Center’s Launch Complex 39A before the storm passes.

Officials at neighboring Patrick Air Force Base said Tuesday that the 45th Space Wing had begun their hurricane preparations sooner than usual so that they can still support Thursday’s launch attempt.

The X-37B mission is the second national security launch for SpaceX since the Air Force certified the Falcon 9 in 2015 to compete for Defense Department business. In May, SpaceX launched a classified payload for the National Reconnaissance Office, NROL-76.

That launch followed back-to-back wins of the first two GPS 3 launch contracts the Air Force put out for bid. A third competition, for the mid-2018 launch of the multi-spacecraft Space Test Program-3 mission, went to United Launch Alliance in June. That launch, which will employ ULA’s most-powerful variant of its Atlas 5 rocket, would have required SpaceX to have used its Falcon Heavy, which is still months from its debut.

The Boeing-built X-37B has been launched into orbit four times since 2010, accumulating a total of 2,085 days in space. All four missions have been launched atop Atlas 5s.

Air Force Secretary Heather Wilson disclosed during an early June congressional hearing that SpaceX, not ULA, would be launching X-37B this time around. She suggested that price was a factor in the Air Force’s decision to go with Falcon 9. “The benefit we’re seeing now is competition,” she said. “There are some very exciting things happening in commercial space that bring the opportunity for assured access to space at a very competitive price.”

SpaceX raced Hurricane Irma this morning to get its Falcon 9 rocket off the pad at Cape Canaveral and launch the Air Force's X-37B—an autonomous spaceplane that orbits for hundreds of days at a time on classified missions—up into orbit. The successful launch and Falcon 9 first stage landing was SpaceX's second national security payload, following a spy satellite launch for the NRO in May, and it's the first time SpaceX launched the Air Force's autonomous mini-space shuttle.
