Northrop Grumman Corp. broke ground on a new $20 million Maryland Space Assembly and Test (M-SAT) facility on its Baltimore campus adjacent to Baltimore Washington International Thurgood Marshall Airport. The 25,000-ft² building is designed to handle space payload integration programs. The M-SAT space assembly, integration, and test building will feature the largest clean-room facility on the company's Baltimore campus: a three-story high-bay area that will house operations for space programs. Northrop Grumman currently develops and delivers space payloads at its Baltimore campus using several smaller space assembly facilities. This new, larger building will allow for expanded payload production to meet growth in the company's space business. The building will house up to 80 engineers and technicians working on space systems assembly, integration, and testing, including lab space for testbed development and testing. Construction of the new facility is expected to be completed during the summer of 2015.
