The CloudSAT flight project was supposed to launch last Friday. Technical difficulties with another satellite that is being launched with CloudSAT have led to a postponement to at least tomorrow (Tuesday) morning. I spent two years developing plans for CloudSAT . It has a special type of profiling radar that will orbit Earth and will provide three-dimensional images of clouds and the motions of particles in clouds. This will help scientists and meteorologists learn more about the movements of storms, including hurricanes and tornadoes. We hope that this mission provides fundamental new knowledge that might help save lives and property in the future.
