Computer Sciences got a $1-billion contract.

The contract, the largest in the El Segundo company’s history, is for systems engineering and analysis services at the National Aeronautics and Space Administration’s Goddard Space Flight Center in Greenbelt, Md. The 10-year contract also consolidates three separate contracts that total about $40 million in revenue a year, the company said. Computer Sciences said it anticipates an annual revenue increase of about $25 million for additional work performed under the contract.
