The National Polar-orbiting Operational Environmental Satellite System Preparatory Project, or NPP, launched successfully on a Delta 2 rocket early today at at 5:48 a.m. EDT 09:48 GMT (or precisely at 2:48:01.828 a.m. PDT, according to NASA's Twitter feed). The next generation satellite will measure both global climate changes and key weather variables, as well as test new technologies for future Earth observing satellites.

The spacecraft has also successfully separated and is now in orbit. The separation video is below.
