NASA Makes Use of Historic Test Site for New Robotic Lander Prototype Tests

http://nasa-satellites.blogspot.com/
Today, engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., began the first phase of integrated system tests on a new robotic lander prototype at Redstone Test Center’s propulsion test facility on the U.S. Army Redstone Arsenal, also in Huntsville. These tests will aid in the design and development of a new generation of small, smart, versatile robotic landers capable of performing science and exploration research on the surface of the moon or other airless bodies, including near-Earth asteroids. This initial test phase, or strapdown testing, allows the engineering team to fully check out the integrated lander prototype before moving to more complex free flight tests.

The team secures, or straps down, the prototype during hot fire tests to validate the propulsion system's response to the flight guidance, navigation and control algorithms and flight software prior to autonomous free flight testing. "Moving the robotic lander tests to the Redstone Test Center facility is a good example of intergovernmental collaboration at its best," said Larry Hill, Robotic Lunar Lander Development Project Manager Test Director, at the Marshall Center. "Engineers and technicians from NASA, the Army and our Huntsville-based support contractor, Teledyne Brown Engineering, have worked tirelessly over the last month to modify the historic test facility formerly used for missile testing to accommodate NASA's lander test in record time, saving NASA time and money."

"Our team has been on a record paced design and development schedule to deliver the robotic lander prototype to the test site," said Julie Bassler, Robotic Lunar Lander Development Project Manager. "We have succeeded in designing, building and testing this new lander prototype in a short 17 months with an in-house NASA Marshall team in collaboration with the our partners" Johns Hopkins Applied Physics Laboratory of Laurel, Md., and the Von Braun Center for Science and Innovation in Huntsville. The flight test program includes three phases of testing culminating in free flight testing for periods up to sixty seconds scheduled for summer 2011. The prototype provides a platform to develop and test algorithms, sensors, avionics, software, landing legs, and integrated system elements to support autonomous landings on airless bodies, where aero-braking and parachutes are not options. 

NASA Appoints Constellation Program Managers

http://nasa-satellites.blogspot.com/
Lawrence D. Thomas has been appointed manager of NASA's Constellation Program, which manages the effort to take humans beyond low-Earth orbit and develop the next generation launch vehicle and spacecraft. Charles M. Stegemoeller has been appointed as deputy program manager. He and Thomas will be based at NASA's Johnson Space Center in Houston.

Thomas most recently served as the deputy program manager of the Constellation Program at NASA's Marshall Space Flight Center, Huntsville, Ala. He began his NASA career in 1983 as an aerospace systems engineer at Marshall's Science and Engineering Directorate.

He served in leadership positions at Marshall including manager of the Systems Engineering and Analysis Office for the Second Generation Reusable Launch Vehicle Program Office, and chief of the Systems Engineering Division, Spacecraft and Vehicle Systems Department. Thomas also spent two years at Johnson as manager of the Vehicle Analysis and Integration Office in the International Space Station Program.
