NASA is now blogging about earth science. From the first post:

The “What On Earth” blog is composed by the science writers, producers, and educators who cover NASA from the inside. We are former journalists and scientists; communications majors and science majors; news hounds and would-be poets. We work with NASA-funded scientists to tell their stories; periodically they will write for themselves in this forum.

Our goal is to provide glimpses of the everydays of Earth science — the field campaigns, lab experiments, technology development – that illuminate the work behind the breakthroughs. We hope to share the evolution of scientific thinking and debates, and the practical application of NASA science in society. Most of all, we want to share the fun we have watching science in progress.
