Earth's gravity revealed in unprecedented detail →
31 March 2011 After just two years in orbit, ESA’s GOCE satellite has gathered enough data to map Earth’s gravity with unrivalled precision. Scientists now have access to the most accurate model of the ‘geoid’ ever produced to further our understanding of how Earth works.
Apologies for the low number of posts recently. Been a little busy. Normal service will be resumed shortly!

Cassini Finds Saturn Sends Mixed Signals →
Like a petulant adolescent, Saturn is sending out mixed signals.
Recent data from NASA’s Cassini spacecraft show that the variation in radio waves controlled by the planet’s rotation is different in the northern and southern hemispheres. Moreover, the northern and southern rotational variations also appear to change with the Saturnian seasons, and the hemispheres have actually...

Dawn Opens its Eyes, Checks its Instruments →
After a hibernation of about six months, the framing cameras on board NASA’s Dawn spacecraft have again ventured a look into the stars. The spacecraft also powered up its visible and infrared mapping spectrometer, which investigates surface mineralogy, and the gamma ray and neutron detector, which detects elemental composition. The reactivation prepares the instruments for the May approach...
