SpaceX test-fired a Falcon 9 rocket at Cape Canaveral Friday evening, igniting nine Merlin engines for several seconds while hold-down restraints kept the launcher on the ground. The company also confirmed the rocket is scheduled for takeoff Wednesday on a space station resupply mission, three days later than previously planned.

Japan’s sixth HTV supply ship is slated to depart a picturesque spaceport on Tanegashima Island on Friday to start a four-day pursuit of the International Space Station with a cache of experiments, supplies and six lithium-ion batteries to begin overhauling the orbiting lab’s vast electrical system.

SpaceX’s ground team hydraulically hoisted a 213-foot-tall Falcon 9 rocket vertical at pad 39A at NASA’s Kennedy Space Center before dawn Monday ahead of a planned liftoff with a space station-bound robotic resupply craft.
