  • Lawson, Peter (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2006., 2006-07-24)
  • Cheng, Y.; Johnson, A. E.; Matthies, L. H.; Olson, C. F. (2003-02-09)
    In this paper, a new crater detection algorithm is suggested. Experimental studies show that this new algorithm can achieve sub-pixel accuracy in position, its detection rate is better than 90% and its false alarm rate ...
  • Huang, Shouhua; Calhoun, Malcolm; Tjoelker, Robert (Pasadena, CA : Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2006., 2006-06-05)
    An array of three antennas has recently been developed at the NASA Jet Propulsion Laboratory capable of detecting signals at X and Ka band. The array requires a common frequency reference and high precision phase alignment ...
  • Maleki, L.; Yu, N.; Matsko, A. (2003-01-05)
    Optical measurements of a gravitational field with sensitivity close to the sensitivity of atomic devices are possible if one detects properties of light after its interaction with optically thick atomic cloud moving freely ...
  • Dubovitsky, S.; Lay, O. P.; Peters, R. D.; Abramovici, A.; Asbury, C. G.; Kuhnert, A. C.; Mulder, J. L. (2002-10-29)
    We describe a high-precision inter-spacecraft metrology system designed for NASA 's StarLight mission, a space-based separated-spacecraft stellar interferometer. It consists of dual-target linear metrology, based on a ...
  • Catanzaro, B.; ; ; ; ; ; ; (2001-08-22)
    The Herschel Space Observatory (formerly known as FIRST) consists of a 3.5 m space telescope designed for use in the long IR and sub-milimeter wavebands. To demonstrate the viability of a carbon fiber composite telescope ...
  • Vaughan, Arthur H.; Korechoff, Robert P. (1993-07-11)
    This paper describes the use of a Hartmann-type pupil mask and CCD Camera to perform wavefront and focus validation of the Hubble Space Telescope simulator before and during environmental testing of the second-generation ...
  • Marzwell, Neville; Thakoor, Sarita (1997-07)
    Optically/electrically operable flexible film microactuators that can offer upto two orders higher efficiency of photonic to mechanical conversion compared to ceramic actuators are conceptualised.
