John C. Stennis Space Center

The John C. Stennis Space Center (SSC) is a NASA rocket testing facility. It is located in Hancock County, Mississippi, on the banks of the Pearl River at the MississippiLouisiana border. , it is NASA's largest rocket engine test facility. There are over 30 local, state, national, international, private, and public companies and agencies using SSC for their rocket testing facilities.
== History ==
The initial requirements for NASA's proposed rocket testing facility required the site to be located between the rockets' manufacturing facility at Michoud Assembly Facility in eastern New Orleans, Louisiana and the launch facility at the Kennedy Space Center in Florida. Also, the site required barge access as the rocket motors to be tested for Apollo were too large for overland transport.
NASA announced formation of the Mississippi Test Facility (now known as Stennis Space Center) on Oct. 25, 1961, for testing engines for the Apollo Program. A high-terrace area bordering the East Pearl River in Hancock County, Miss., was selected for its location. NASA entrusted the U.S. Army Corps of Engineers with the difficult task to procure each land parcel either by directly purchasing the land or through acquisition of a perpetual easement.〔http://www.nasa.gov/centers/stennis/pdf/697602main_October_12_Lagniappe.pdf〕
The selected area was thinly populated and met all other requirements; however before construction began, five small communities (Gainesville, Logtown, Napoleon, Santa Rosa, and Westonia), plus the northern portion of a sixth (Pearlington), and a combined population of 700 families had to be completely relocated off the facility. The effort acquired more than 3,200 parcels of privately owned land – 786 residences, 16 churches, 19 stores, three schools and a wide assortment of commercial buildings, including nightclubs and community centers. Remnants of the communities, including city streets and a one-room school house, still exist within the facility.〔
The site was selected on October 25, 1961 on the Mississippi Test Facility or Pearl River Site. On December 18, 1961 NASA officially designated the facility as NASA Mississippi Test Operations. The test area (officially known as the Fee Area) is surrounded by a acoustical buffer zone. The facility's large concrete and metal rocket propulsion test stands were originally used to test-fire the first and second stages of the Saturn V rockets. The facility was renamed again to Mississippi Test Facility on July 1, 1965, became a part of the Marshall Space Flight Center
Starting in 1971, all Space Shuttle Main Engines were flight-certified at Stennis. On June 14, 1974 the site was renamed National Space Technology Laboratories, a name that continued until May 20, 1988 when it was renamed for Mississippi senator and space program supporter John C. Stennis.
With the end of the Apollo and Shuttle programs, use of the base decreased, with economic impact to the surrounding communities. Over the years other government organizations and commercial entities have moved to and left from the facility, in the balance providing a major economic benefit to the communities.
