The NASA Stennis rocket testing facility
. It is located in Hancock County, Mississippi, on the banks of thePearl River (Mississippi–Louisiana) at the Mississippi–Louisiana border. As of 2012, it is NASA’s largest rocket engine test facility.

One of the multiple projects that  NASA and Louisiana Tech University cooperated together on was the development of an experimental DNA analysis instrument that could benefit future NASA astronauts. Zero-gravity testing of the technology occurred in 2011 above the Gulf of Mexico.
Nasa has also established Louisiana Tech University as a regional and state Educator Resource Center to disseminate materials to and assist educators in providing world-class science, technology, engineering, and mathematics (STEM) education nationwide.
