CAPE CANAVERAL, Fla. — SpaceX engineers have replaced a faulty engine valve on a private rocket carrying the first commercial space capsule bound for the International Space Station following the last-second abort during an attempted liftoff Saturday (May 19).
The valve replacement came after SpaceX's Falcon 9 rocket, which will loft the firm's unmanned Dragon capsule toward the station, aborted its launch attempt a half-second before liftoff from a pad here at Cape Canaveral Air Force Station. Technicians investigating the glitch discovered a faulty check valve was to blame for the high engine pressure that forced the booster's engines to unexpectedly shut down.
