Detecting cracks smaller than the eye can detect is an important feature as manufacturers push performance limits to achieve lighter, more efficient spacecraft. Photo Credit: (NASA/Reed P. Elliott)

A slotted ball joint at the base of the rotary stage allows the tank to pivot resulting in helical scans that are more reliable when measuring interior and exterior 3D surface profiles.

Edgar Reyes, a materials engineer and recent graduate of The University of Texas at El Paso, visually inspects a crack identified on the outer surface of a composite overwrapped pressure vessel (COPV) following an internal eddy-current through-wall nondestructive inspection conducted at the NASA White Sands Test Facility in Las Cruces, N.M. Eddy-current testing is one of many electromagnetic testing methods used in nondestructive testing to identify cracks in COPVS that can potentially threaten spacecraft crew and mission success.
