** NASA has approved an extended mission for the Mars Exploration Rovers,
handing them up to five months of overtime assignments as they finish their
three-month prime mission. The mission extension provides $15 million for
operating the rovers through September. The extension more than doubles
exploration for less than a two percent additional investment, if the rovers
remain in working condition. The extended mission has seven new goals for
extending the science and engineering accomplishments of the prime
mission.. --SpaceDaily
** Nanotechnology, a science devoted to engineering things that are
unimaginably small, may pose a health hazard and should be investigated
further, warns a University of Rochester scientist and worldwide expert in
the field, who received a $5.5 million grant to conduct such research. "We
must consider many different issues before we come to a judgment on risk,"
he says. "Foremost is an assessment of potential human and environmental
exposure by different routes: inhalation, ingestion, dermal. Then, what is
their fate in the organism? And what are the risks of cumulative effects,
given that these particles are being mass produced? At this point we're
trying to balance the tremendous opportunity that nanotechnology presents
with any potential harm." --SpaceDaily
