NASA awarded a contract worth a potential $273 million to Houston-based Barrios Technology Ltd. for mission integration services for the international space station (ISS), the agency announced in a June 25 news release.

The fixed-price, indefinite-delivery, indefinite-quantity contract includes a five-year base period that runs Oct. 1 through Dec. 31, 2015, valued at $185.5 million, and a pair of one-year options valued at a combined $87.7 million.

Barrios Technology will provide support engineering and technical services to the space station program, including products and services for mission planning, integration and operations, and Russian language and logistics services.

TechTrans International, a Houston company that employed NASA Administrator Charles Bolden as a senior vice president from 2003 to 2005, will serve as a major subcontractor on the contract.

The bulk of the work is expected to be performed at or near NASA’s Johnson Space Center in Houston and Kennedy Space Center in Florida. Work also will be performed outside the United States, including Russia and Kazakhstan.
