Mariner 9 - Experiments

Experiments

  1. Ultraviolet Spectrometer (UVS)
  2. Infrared Interferometer Spectrometer (IRIS)
  3. Celestial Mechanics (not a separate instrument; it relied upon tracking measurements including range, range rate, and Doppler)
  4. S-Band Occultation (not a separate instrument; experiment observed the attenuation of the communication signal as the orbiting satellite passed out of view)
  5. Infrared Radiometer (IRR)
  6. Visual Imaging System – at the lower orbit of Mariner 9, half that of Mariner 6 and Mariner 7 flyby missions, and a vastly improved imaging system, Mariner 9 achieved a resolution of 320 feet (98 m) per pixel, whereas previous Martian probes had achieved only approximately 2,600 feet (790 m) per pixel.

Famous quotes containing the word experiments:

    “The man who invented Eskimo Pie made a million dollars, so one is told, but E.E. Cummings, whose verse has been appearing off and on for three years now, and whose experiments should not be more appalling to those interested in poetry than the experiment of surrounding ice-cream with a layer of chocolate was to those interested in soda fountains, has hardly made a dent in the doughy minds of our so-called poetry lovers.”
    —John Dos Passos (1896–1970)

    “Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
    —James Conant (1893–1978)

    “There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.”
    —Denis Diderot (1713–1784)
