AEROSPACE

Rockwell Team Chosen to Build New Launchers: The Seal Beach-based aerospace giant and Orbital Sciences Corp. of Dulles, Va., will commit about $100 million to build at least two reusable vehicles to launch satellites, under the aegis of the National Aeronautics and Space Administration. NASA will contribute $70 million to the project, called the X-34, whose launches would start in the late 1990s. The X-34 would also provide data for development of a larger, “low-cost” reusable launch rocket, the X-33, that would succeed the Rockwell-built space shuttles and be used commercially. NASA also tapped three teams--including one that includes Rockwell, Orbital and Northrop Grumman Corp.--to develop competing designs for that vehicle.
