NASA Kennedy Space Center prepares for Hurricane Dorian

As Hurricane Dorian heads for Florida, the Kennedy Space Center is preparing for what could be a category 4 storm.

In a tweet on Wednesday, NASA posted a video explaining how it would use a tracked carrier to pick up its mobile launcher near the vehicle assembly building as a precautionary measure.

"Before the arrival of #HurricaneDorian, @NASAGroundSys has been moved to Launch Pad 39B in the event that a call is made to move the mobile launcher inside the vehicle building," reads on Twitter from the Kennedy Space Center. "If that happens, the ML and the crawler will wait for the storm in the VAB."

The video explains that the tracked carrier is the vehicle that moves the spacecraft around the launch complex. Meanwhile, the mobile launcher measures approximately 400 meters high, making it the type of structure that you might want to avoid in the shelter of a hurricane. It is necessary to "assemble, process and launch NASA's powerful space launch rocket and Orion spacecraft".

Dorian is expected to become a major hurricane Friday and remain dangerous throughout the weekend, the National Hurricane Center announced on Thursday. It could be a Category 4 storm when it hits the ground on Monday, with maximum sustained winds of 130 mph. From now on, the land could land anywhere on the Atlantic coast of Florida.

NASA did not immediately respond to a request for additional comment.
