Part Ojibwe, All NASA: Linda Spuler’s Role in Protecting Johnson Space Center 

NeRD

Linda Spuler, emergency manager at NASA’s Johnson Space Center in Houston, believes that everyone has a story. “Our stories highlight what we have in common, but they also make us each unique,” she said.  Spuler has worked at Johnson for over 32 years, spending most of her career in Center Operations. Her story has involved helping to coordinate emergency response teams at Johnson in preparation for natural disasters. “Since Johnson is situated on the coast, a good portion of my job revolves around planning for hurricanes,” she said.    Spuler has…

Identification of Noise Sources During Launch Using Phased Array Microphone Systems

NeRD

Identification of Noise Sources During Launch Using Phased Array Microphone Systems  Every part of a launch vehicle, launch pad, and ground operation equipment is subjected to the high acoustic load generated during lift-off [1]. Therefore, many extreme measures are taken to try to suppress this acoustic environment by damping with a water deluge system and diverting engine plumes away from the vehicle via flame trenches. Even single decibel reductions of the acoustic levels can translate into a sizable reduction of acoustic loadings, certification needs, operational costs, and even vehicle weight.…

Trajectory Reverse Engineering 

NeRD

A strategy for transferring spacecraft trajectories between flight mechanics tools, called Trajectory Reverse Engineering (TRE), has been developed[1]. This innovative technique has been designed to be generic, enabling its application between any pair of tools, and to be resilient to the differences found in the dynamical and numerical models unique to each tool. The TRE technique was developed as part of the NESC study, Flight Mechanics Analysis Tools Interoperability and Component Sharing, to develop interfaces to support interoperability between several of NASA’s institutional flight mechanics tools.   The development of space…
