Probe Launches To Map Earth's Gravity In Best Detail Yet



From New Scientist:

A sleek satellite that is set to make the most detailed map of the Earth's gravity took to the skies on Tuesday. The probe is expected to make important contributions to ocean current measurements and climate models.

If all goes well, the satellite will assume an orbit some 285 km above the Earth, gradually falling to an altitude of 268 km, where the probe will take much of its science data. It will remain in orbit for at least two years, beginning science operations in late August or early September when the probe will have sufficient solar power to do its observations.
