Editor’s Corner

Michael King, EOS Senior Project Scientist

I’m pleased to announce that, after several unsuccessful attempts, the CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) missions were successfully launched aboard a Delta-II rocket from Vandenberg Air Force Base in California at 10:02 UTC on April 28. Each spacecraft will transmit pulses of energy and measure the pulses scattered back to the satellite. CloudSat’s Cloud-Profiling Radar is more than 1,000 times more sensitive than typical weather radar. It can detect clouds and distinguish between cloud particles and precipitation. CALIPSO’s polarization lidar can detect aerosol particles and distinguish between aerosol and cloud particles. Lidar, similar in principle to radar, uses reflected light to determine the characteristics of the target area.

Sixty-two minutes after liftoff, CALIPSO separated from the rocket’s second stage. CloudSat followed 35 minutes later. Ground controllers successfully acquired signals from...
