Science:
Problems with a key sensor could further delay the first flight
of a troubled $12.5 billion U.S. weather and climate satellite
program. Science has learned that the technical problems not
only threaten the planned June 2010 inaugural launch of the
National Polar-orbiting Operational Environmental Satellite
System (NPOESS) but also could imperil the satellites' ability
to collect reliable climate measurements during the next
decade.
