In the first episode of A Green Space — A Green Earth at Astrocast.TV, my friend and astrophysicist Bente Lilja Bye gives a superb overview about the Gravity field and steady-state Ocean Circulation Explorer (GOCE) that was finally launched in March. It’s a captivating show, detailing the history and science behind the study of geodesy (the gravitational field, shape and rotation of the Earth).
You may not be familiar with geodesy, but it is critical to advancing our understanding of the planet we live on. For example, GOCE observations could aid prediction techniques for earthquakes, or refine GPS data; suddenly geodesy has a very real and immediate relevance to us on the ground.
Be sure to check out the video below, it’s a very slick production. Great job Bente!

You are too kind, Ian! 🙂
This is really a great help if we can at least determine or estimate when and where earthquake will occur, in that people will be able to prepare. Plese continue to to send information like this. Thank you for sharing
