NASA moon-mapping mission to come to a crashing end
CAPE CANAVERAL, Florida (Reuters) - NASA plans to crash a
pair of small robotic science probes into the moon next week
after a successful year-long mission to learn what lies beneath
the lunar surface, officials said on Thursday. The twin Gravity
Recovery and Interior Laboratory, or GRAIL, spacecraft will
make suicidal plunges on Monday into a mountain near the moon's
north pole, a site selected to avoid the chance of hitting any
of the Apollo or other lunar relics.
Human link to climate change stronger than ever: draft
report
LONDON (Reuters) - International climate scientists are
more certain than ever that humans are responsible for global
warming, rising sea levels and extreme weather events,
according to a leaked draft report by an influential panel of
experts. The early draft, which is still subject to change
before a final version is released in late 2013, showed that a
rise in global average temperatures since pre-industrial times
was set to exceed 2 degrees Celsius by 2100, and may reach 4.8
Celsius.
