NASA’s Stennis Space Center is located on 13,500 acres in Hancock County, Mississippi, surrounded by another 125,000 acres that act as a buffer for the deafening roar of rocket engines. It has witnessed the flame and smoke spout from the...

When engineers explore designs for safer, more fuel efficient, or faster aircraft, they encounter a common problem: they never know exactly what will happen until the vehicle gets off the ground.
