Kennedy Space Center Director Bob Cabana tours Marshall Space Flight Center

Kennedy Space Center Director Robert Cabana, center, receives an update on SLS hardware from Heather Haney, left, an engineer in the Space Launch System stages office, and Mark White, lead test engineer for the SLS core stage engine section, on July 16 in Marshall's Building 4619. Cabana, Haney and White are standing in front of a structural test version of the Intertank, the 212-foot-tall backbone of the SLS rocket. The structural test article is undergoing critical testing as engineers push, pull and bend the hardware with millions of pounds of force to ensure it can withstand the forces of launch and ascent.
