摘      要：Even in an age of increasing spacecraft exploration, telescopic observations of Mars continue to provide new data and new insights into the nature of the Martian surface, atmosphere, and climate. Three major technological advances in the last decade, combinde, have allowed telescopic observations to increase our knowledge of the planet: (1) Advances in infrared, near-infrared, and radio wavelength array detector and telescope technology, allowing high spatial and/ or high spectral resolution imaging in new and diagnostic wavelength regions; (2) The advent of routine space-based telescopic observations of Mars using the Hubble Space Telescope , providing the ability to study the planet at high spatial resolution over a much longer part of its orbit than from groundbased telescopes, and offsetting some of the inherent loss in resolution associated with the recent series of aphelic oppositions of the planet; and (3) The widespread use and availability of CCD cameras and powerful telescopes in the 10 -
