Hurricane Gonzalo has pushed the next private cargo mission to the International Space Station back by at least three days.

Orbital Sciences' Cygnus spacecraft was scheduled to blast off on an unmanned supply run to the orbiting lab from NASA's Wallops Flight Facility in Virginia on Oct. 24. But that liftoff has been delayed until at least Oct. 27 because Gonzalo is about to hit Bermuda, where key tracking equipment for Cygnus' Antares rocket is located.

"Once the hurricane has passed Bermuda, a team from NASA’s Wallops Flight Facility Range will return to the tracking site to assess the situation and begin the process of re-enabling the site's functionality to support the launch," Orbital Sciences representatives wrote in a mission update Wednesday (Oct. 15).

"Depending on the impact of the storm on Bermuda's essential infrastructure systems such as transportation, power and communications, the launch date could be moved later" than Oct. 27, they added.

Whenever it takes place, the Cygnus/Antares launch will kick off Virginia-based Orbital Sciences' third robotic cargo mission to the space station for NASA. The company signed a $1.9 billion deal with the agency to complete eight such flights.

California-based SpaceX also makes unmanned supply runs to the orbiting lab for NASA using its Dragon capsule and Falcon 9 rocket. SpaceX's $1.6 billion contract calls for the firm to fly 12 missions; it has completed three of them to date and is in the middle of the fourth. (Last month, NASA also awarded SpaceX a $2.6 billion contract to fly astronauts to and from the space station using a manned version of Dragon, with operational flights envisioned to start in 2017.)

Gonzalo took shape as a tropical storm on Sunday (Oct. 12) and intensified into a hurricane on Tuesday (Oct. 14). By Wednesday, Gonzalo rated as a Category 4 hurricane, meaning it boasted maximum sustained winds between 130 and 156 mph (209 to 251 km/h).
