Lockheed Martin Information Systems and Global Services of Gaithersburg, Md., was awarded a $165 million contract extension to continue supporting NASA Johnson Space Center’s Mission Operations Directorate.

Under the contract NASA announced Dec. 12, Lockheed Martin and its Houston-based subcontractors Cimarron Software Services Inc. and United Space Alliance will support hardware, software, and data and display systems used to train for and execute NASA human spaceflight missions.

The majority of the work will be performed in Houston.

Lockheed Martin won the $755 million Facilities Development and Operations Contract (FDOC) in November 2008. The one-year extension exercises the first of two potential options and increases the total value of the contract through September 2013 to $919.5 million.
