WASHINGTON, April 20 (Reuters) - The Federal Aviation Administration said Monday it is ordering an investigation into Blue Origin New Glenn 3 second-stage failure on Sunday.

The FAA is requiring Blue Origin to conduct a mishap investigation and will approve Blue Origin's final report and any corrective actions before it can resume flights. The rocket launched successfully from Florida but the rocket failed to deploy the AST SpaceMobile communications satellite it was carrying into the correct orbit.
