A bright spot in Hubble's troubled eye.

A bright spot in Hubble's troubled eye

Flawed, yes, but the Hubble Space Telescope Hubble Space Telescope (HST), the first large optical orbiting observatory. Built from 1978 to 1990 at a cost of $1.5 billion, the HST (named for astronomer E. P. Hubble) was expected to provide the clearest view yet obtained of the universe.  nonetheless provides the sharpest images of Mars yet taken from Earth's vicinity. It can capture details about 50 kilometers across, compared with the 150-km resolution of ground-based photos.

A seven-member team led by Philip James Philip James (May 17, 1890 – November 1, 1975) was an American composer, conductor and music educator.

James was born in Jersey City, New Jersey.
 of the University of Toledo National recognition
In its 125-year history UT has garnered several national accolades. The University’s programs, faculty and facilities have been highlighted in the media, including
 in Ohio now plans periodic Hubble observations for a long-term study of Mars' changing surface and atmosphere, including its occasional global dust storms.

The first image in the series, made Dec. 13 and released last month, shows Syrtis Major Syrtis Major Planum is a "dark spot" (an albedo feature) located in the boundary between the northern lowlands and southern highlands of Mars. It was discovered, on the basis of data from Mars Global Surveyor, to be a low-relief shield volcano[1]  Planitia (dark area, middle). Such Martian dark regions appear covered with coarse sand grains about 100 microns across, says Steve Lee of the University of Colorado University of Colorado may refer to:
  • University of Colorado at Boulder (flagship campus)
  • University of Colorado at Colorado Springs
  • University of Colorado at Denver and Health Sciences Center
  • University of Colorado system
 in Boulder; the lighter surface apparently consists of dust particles no bigger than 1 micron.

The light-blue feature along the picture's upper-right edge represents a "hood" of water ice in the atmospher above the Martian north pole, extending to a height of 10 kilometers or more. Using ultraviolet filters, the team has also produced what one member calls the first ozone map of Mars.
