Here's another chance to play geographical detective! This false-color image was acquired by the Multi-angle Imaging SpectroRadiometer (MISR) in late June, 2002, and represents an area of about 292 kilometers x 370 kilometers. Data from the near-infrared, red and blue spectral bands of MISR's downward-viewing (nadir) camera are displayed as red, green and blue, respectively, causing highly vegetated areas to appear red

Answers will be published on the MISR Quiz page in conjunction with the next weekly image release. The names and home towns of respondents who answer all questions correctly by the deadline will also be published in the order responses were received. The first 3 people on this list who are not affiliated with NASA, JPL, or MISR and who have not previously won a prize will be sent a print of the image.

A new "Where on Earth...?" mystery appears as the MISR "image of the week" approximately once every two months. A new image of the week is released every Wednesday at noon Pacific time on the MISR home page, http://www-misr.jpl.nasa.gov. The image also appears on the Earth Observatory, http://earthobservatory.nasa.gov/, and on the Atmospheric Sciences Data Center home page, http://eosweb.larc.nasa.gov/, though usually with a several-hour delay.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.
