UNITED NEWS INTERNATIONAL (UNI) — SpaceX isn’t taking responsibility for a failed mission.

A SpaceX Falcon 9 rocket launched Sunday, Jan. 7 in Florida with the goal of deploying a multi-billion-dollar U.S. spy satellite named Zuma into space.

Live-stream coverage showed apparent success in stage one. But the second stage, in which the rocket separates from the satellite, was not filmed due to the payload’s classified status.

Neither SpaceX or Zuma’s manufacturer, Northrop Grumman, announced a successful deployment.

Reuters said two U.S. officials later confirmed Zuma either broke apart or fell into the ocean and is a total loss.

SpaceX denied responsibility for the satellite’s loss in a statement released Tuesday, saying the rocket “did everything correctly … no design, operation, or other changes are needed.”

Company President Gwynne Shotwell said the satellite might have malfunctioned or the adapter connecting it to the rocket failed.

SpaceX said the incident won’t affect any future planned launches.
