  • Zernike wavefront sensor (ZWFS) development for Low Order Wavefront Sensing (LOWFS) 
    Wang, Xu; Shi, Fang; Wallace, J. Kent (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2016, 2016-06-26)
    ZWFS is known to be photon noise optimal for measuring low order aberrations. Recently, ZWFS was selected as the baseline LOWFS technology on WFIRST for its sensitivity, accuracy, and its ease of integration with the ...

    Wang, Xu; Shi, Fang; Wallace, J. Kent (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2016, 2016-06-26)
  • Zernike wavefront sensor modeling development for LOWFS on WFIRST-AFTA 
    Wang, Xu; Wallace, J. Kent; Shi, Fang (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2015, 2015-08-09)
    In this paper, we review the theory of ZWFS operation, describe the ZWFS algorithm development, and summarize various numerical sensitivity studies on the sensor performance. In the end, the predicted sensor performance ...
  • Zero Mass, Packageless and Non-Invasive Pressure Transducer 
    Hartley, F. (2000-06-04)
  • Zero to integration in eight months, the Dawn Ground Data System Engineering Challenge. 
    Dubon, Lydia P. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2006., 2006-06-19)
    The Dawn Project has presented the Ground Data System (GDS) with technical challenges driven by cost and schedule constraints commonly associated with National Aeronautics and Space Administration (NASA) Discovery Projects. ...
  • Zodiac II : debris disk science from a balloon 
    Bryden, Geoffrey; Trauba, Wesley; Roberts, Lewis C. Jr.; Bruno, Robin; Unwin, Stephen; Backovsky, Stan; Brugarolas, Paul; Chakrabarti, Supriya; Chen, Pin; Hillenbrand, Lynne; Krist, John; Lillie, Charles; Macintosh, Bruce; Mawet, Dimitri; Mennesson, Bertrand; Moody, Dwight; Rey, Justin; Stapelfeldt, Karl; Stapelfeldt, Karl; Trauger, John; Trauger, John (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2011., 2011-08-21)
    Zodiac II is a proposed balloon-borne science investigation of debris disks around nearby stars. Debris disks are analogs of the Asteroid Belt (mainly rocky) and Kuiper Belt (mainly icy) in our Solar System. Zodiac II will ...
  • Zonal Winds in the Venus Atmosphere 
    Kliore, A. (2000-07-16)
  • Zonal Winds in the Venus Stratosphere (viewgraphs) 
    Kliore, A. (2000-07-16)
  • Δ17O of Martian sulfate : assessment as a tool to recognize the impact of biological sulfur cycling on Mars. 
    Brunner, Benjamin; Coleman, Max L. (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2005., 2005-03-14)
    The Mars Rover-missions demonstrate that there are accessible Martian sulfate deposits (evaporites). These sedimentary rocks could indicate influence of past or present biotic processes even in the absence of traces of ...

    Programs, The Role of Analysis and Testing in Ion Engine Development (1995-09)
    Adequate performance was achieved relatively early in the development of ion engines and most subsequent development programs have focussed on demonstrating adequate engine life. The primary threats to engine reliability ...
