Falcon 9

A SpaceX Falcon 9 rocket took off from Kennedy Space Center’s launch pad 39A on Thursday, then its first stage booster touched down on a nearby landing target after sending a U.S. Air Force X-37B spaceplane toward orbit.

With an eye on dangerous Hurricane Irma’s forecast path toward Florida, SpaceX and the U.S. Air Force are proceeding with preparations to launch an unpiloted reusable military spaceship Thursday on a mission to conduct experiments in orbit, deploy multiple small satellites and glide back to Earth for a runway landing after months or years in space.

Cocooned inside the nose cone of its Falcon 9 rocket booster, the U.S. Air Force’s X-37B spaceplane journeyed from a former space shuttle hangar at NASA’s Kennedy Space Center, past the Vehicle Assembly Building and toward launch pad 39A last week ahead of liftoff Thursday.
