With a permanent human presence aboard the International Space Station (ISS), flight keep a constant watch on the crew’s activities and monitor spacecraft systems, crew control teams at the Mission Control Center in Houston and the Mission Control Center health and safety as they check every system to ensure operations proceed as planned. in Moscow are on duty 7 days a week, 24 hours a day, 365 days a year. Flight controllers Building and maintaining the International Space Station (ISS) requires crew members to to take place during the ISS assembly. To prepare for the spacewalks, crew members train conduct extravehicular activities (spacewalks). More than 130 spacewalks are scheduled in a 6.2-million-gallon pool at the Neutral Buoyancy Laboratory (NBL) in Houston, Texas. Global Hawk The bulbous nose of one of NASAs Global Hawk unmanned aircraft sports a blue-and-white paint scheme after repainting in the Edwards Air Force Base paint shop. Microsystems Fabrication Laboratory Clean Room In this photograph, members of the Research Instrumentation and Sensors Branch at NASA Glenn Research Center work in a clean room. The team fabricates micro-electrical mechanical systems (MEMS), such as pressure sensors and electronics, for jet engines and other high-temperature applications.  In a clean room, the air quality, humidity and temperature are controlled to prevent contamination of sensitive material like MEMS. Delta 4 Shroud Separation Test Boeing Delta 4 shroud separation test in the Space Power Facility (SPF) at NASA Plum Brook Station. The SPF houses the worlds largest space environment simulation chamber, measuring 100-ft in diameter by 122-ft high.
