Stafford-Covey Group Finding Probably Won't Cause Launch
Just three weeks before the space shuttles' Return to Flight, a
NASA advisory group says the space agency has failed to address
three critical safety issues: eliminating critical launch debris,
harden the shuttle against debris impact and figure out a way to
repair the orbiter's heat shield in orbit.
NASA's Deep Impact spacecraft observed a massive, short-lived
outburst of ice or other particles from comet Tempel 1 that
temporarily expanded the size and reflectivity of the cloud of dust
and gas (coma) that surrounds the comet nucleus.
Scientists are fascinated by a dark, lake-like feature recently
observed on Saturn's moon Titan. NASA's Cassini spacecraft captured
a series of images showing a marking, darker than anything else
around it. It is remarkably lake-like, with smooth, shore-like
boundaries unlike any seen previously on Titan.
