Lockheed Martin has been awarded a five-year contract estimated at $120 million to provide call center services for the Department of Homeland Security’s U.S. Citizenship and Immigration Services. The contract is one of two awarded by USCIS to operate its National Customer Service Center, which annually serves nearly 10 million callers requesting information about immigration services and benefits. Raytheon Company’s (NYSE:RTN) Visible Infrared Imaging Radiometer Suite (VIIRS) advanced sensor engineering development unit (EDU) has entered thermal vacuum testing, achieving another milestone for the National Polar-orbiting Operational Environmental Satellite System (NPOESS). The testing occurs in one of Raytheon’s space-qualified thermal vacuum chambers, which replicates the extreme heat and freezing cold cycles that spacecraft and sensors experience in space.
