MIAMI: SpaceX scrubbed its planned Dragon cargo launch to the International Space Station just seconds before liftoff on Saturday due to a technical issue with the Falcon 9 rocket engine.
"We did abort today," a SpaceX spokesman said, describing the move as having been made "out of an abundance of caution."
Engineers plan to "take a closer look at the position of the second stage engine nozzle," the California-based company said on Twitter.
The unmanned cargo ship is packed with food, gear and science experiments for the astronauts living in orbit.
The next launch attempt is scheduled for 9:38 am Sunday (1438 GMT).
