WFF supports all of NASA's Mission Directorates and practically all of their respective themes: Science Mission Directorate Earth Science Solar System Exploration The Universe Heliophysics Exploration Mission Directorate Constellation Systems Exploration Systems Research and Technology Human Systems Research and Technology Aeronautics Mission Directorate Aeronautics Technology Space Operations Mission Directorate International Space Station Space Shuttle Space and Flight Support Commercial spaceport In 1998, the Virginia Commercial Space Flight Authority, later joined by Maryland, built the Mid-Atlantic Regional Spaceport at Wallops on land leased from NASA. In December 2006, the facility made its first launch. Visitor center The Wallops Visitor Center has a variety of hands-on exhibits and hosts weekly educational activities and programs to enable children to explore and learn about the technologies designed and used by NASA researchers and scientists. In addition, one Saturday each month, NASA invites model rocketry enthusiasts to launch their own rockets from the WFF rocket launch site. NASA personnel also participate, launching models of various rockets and explaining the spacecraft they carry in real life. The schedule for sounding rocket launches from WFF is posted on its official Web site. Education For many years WFF was home to the NSIP Sub-SEM and SEM projects. NSIP stands for the NASA Student Involvement Project, the Sub-SEM project was to design one of four experiments that would be inserted into an ORION-II one-stage rocket and launched above 98 percent of the atmosphere, and experience over 30 Gs of centrifugal force, while SEM was to design an experiment that would be flown on a future Space Shuttle mission. Each project gave 16 students and four teachers (four students and one teacher from each high school) the opportunity to spend an almost all-expense-paid week at WFF. Normally the students and teachers stayed in the Mariner Motel, now a Holiday Inn, conducting experiments and learning about the facility. Following the presidential mandate and budget cuts the entire NSIP program, SEM and Sub-SEM included, was shut down. Accidents On April 2, 1957, a Lockheed P2V-6 Neptune exploded in midair after takeoff from what was then known as Naval Auxiliary Air Station Chincoteague. All eleven occupants of the aircraft died. On October 23, 1995, the maiden flight of a Conestoga 1620 rocket failed 46 seconds after liftoff, resulting in disintegration. EER Space Systems, Conestoga's manufacturer, concluded that low frequency noise from an unknown source upset the guidance system on the rocket causing it
