NASA on Monday said it will roll its giant moon rocket off its launchpad in Florida and back to the assembly building to protect the vehicle from an advancing Hurricane Ian, whose strengthening winds are forecast to lash the Kennedy Space Center later this week.
“The decision allows time for employees to address the needs of their families and protect the integrated rocket and spacecraft system,” NASA said in a statement.
The Space Launch System’s rollback to the Vehicle Assembly Building is a slow and delicate process that takes between eight and 11 hours to complete the roughly 5 mile trip.
Hurricane Ian is just the latest delay for the rocket, after weeks of troubleshooting by NASA after engineers detected a leak of supercooled hydrogen propellant in a valve while fueling the rocket during an earlier attempt this month to launch.
Recent tests showed positive signs the leak had been fixed and the rocket would again be ready for another launch attempt. But the latest weather models showing Hurricane Ian approaching Florida prompted new worries over whether the rocket could withstand the storm’s winds.
