I’m happy to report that on June 19, NASA’s Quick Scatterometer (QuikSCAT) satellite was launched aboard an Air Force Titan II launch vehicle from Vandenberg Air Force Base. QuikSCAT’s SeaWinds microwave scatterometer will provide new near-surface wind speed and direction measurements under all weather and cloud conditions over the Earth’s oceans. The satellite achieved its initial elliptical orbit with a maximum altitude of about 800 km above the Earth’s surface about an hour after launch.

During the first two weeks after launch, QuikSCAT fired its thrusters as many as 25 times to circularize and gradually fine-tune its polar orbit. Eighteen days after launch, the SeaWinds instrument was...
