Who's Who at NASA

Leslie Molzahn, Operations Engineer, Dryden Space Flight Center, Edwards, CA

Leslie MolzahnSupersonic speed would allow travelers to cut significantly their travel time. However, because of the resulting sonic booms, the Federal Aviation Administration (FAA) and similar associations restrict supersonic travel to transoceanic only. Gulfstream Aerospace Corp. (Savannah, GA) partnered with NASA Dryden in a commercial investigation of the Quiet Spike, a sonic-boom suppression system. Leslie Molzahn was part of Dryden’s investigative team

Dr. Karen Jackson, Aerospace Engineer, Landing and Impact Research (LandIR) Facility

NASA Langley Research Center, Hampton, VA Dr. Karen JacksonIn a crash, keeping the occupants alive and uninjured is paramount. In order to study the dynamics of an impact, military and general aviation aircraft, like cars, must be tested for their ability to keep their riders safe. A part of Structural Dynamics Branch in the Research and Technology Directorate at NASA Langley, the Landing and Impact Research Facility (LandIR) tests aircraft by crashing them. Dr. Karen Jackson is part of the research team.

Julia W. Loftis, Associate Chief for Information Systems Technology

NASA Goddard Space Flight Center, Greenbelt, MD Julia W. LoftisWhile a single, peer-to-peer rover can cover a large territory and gather a wealth of information, an entire fleet of rovers could cover even more ground. However, controlling multiple platforms poses a much different set of criteria. To answer the need to control and communicate with multiple vehicles doing a similar task, the Adaptive Sensor Fleet (ASF) software was developed by NASA researchers, and is able to coordinate several platforms at once. Julia Loftis oversaw the strategic planning of the project.

Ginger N. Flores, LOCAD Project Manager, NASA Marshall Space Flight Center, Huntsville, AL

Diagnosis on Earth is a fairly simple procedure, done at any hospital or medical center. In space flight, however, where doctors and even basic medical equipment may be lacking, falling ill is a serious matter for both astronaut and ground control. Using horseshoe crab blood as a reactive agent, the Lab-On-a-Chip Application Development-Portable Test System (LOCAD-PTS) is a handheld device developed by NASA researchers to help identify microorganisms. Ginger N. Flores is the LOCAD project manager.

Bill Sheredy, Project Manager for SAME (Smoke Aerosol Measurement Experiment)

NASA Glenn Research Center, Cleveland, OH Bill SheredyFire is deadly and unpredictable on Earth; in an enclosed space vehicle in orbit, its presence takes on even more serious implications. To prevent the threat of smoke and fire on missions, NASA conducted the Smoke Aerosol Measurement Experiment (SAME), designed to create devices that will adequately detect combustion in a zero-gravity environment. Heading SAME is NASA researcher Bill Sheredy.

Dr. Walter Merrill, Associate for Business Development, John H. Glenn Research Center, Cleveland, OH

Dr. Walter MerrillDr. Walter Merrill is involved in a variety of programs aimed at forming partnerships with private and public entities. For the past five years, he has been working towards developing microelectromechanical systems (MEMS) devices that are made out silicon carbide. In that capacity, Dr. Merrill was instrumental in helping NASA Glenn Research Center, the State of Ohio, and Case Western Reserve University launch the Glennan Microsystems Initiative to address the research, development, and application needs of NASA and industry in the field of MEMS.
