NASA is using Hexagon technology to help develop the next deep-space rocket, implementing Leica robotic total stations at the Marshall Space Flight Center to qualify test hardware for the Space Launch System (SLS). The SLS is an advanced launch vehicle for a new era of human exploration beyond Earth’s orbit. Hexagon instruments are streaming continuous deflection measurements during sophisticated testing designed to simulate flight conditions. With its unprecedented capabilities, SLS represents the next generation of rocket design. Hexagon’s surveillance provides highly accurate data that is helping NASA engineers understand article performance and guide them in future rocket development.
