摘要

NASA and the U.S. Geologi-cal Survey are again press-ing the case for building a dedicated land imaging satellite to replace a pair of old and ailing Landsat spacecraft not expected to survive the decade, according to U.S. government officials and industry sources. The White House authorized a plan just last year to ensure long-term continuity in the collection of Landsat imagery by including a land imager on the next generation of U.S. polar-orbiting weather satellites expected to start launching around 2010. The White House plan, the product of months of interagency negotiations, left open the possibility of the government funding one final dedicated satellite mission to bridge the gap between the demise of the increasingly creaky Landsat 7 and the launch of the first of six new civilian and military weather satellites that make up the National Polar-orbiting Environmental Satellite System (NPOESS).
