Unmanned NASA storm sentinels set for hurricane study

Ah, June. It marks the end of school, the start of summer … and the official start of the 2012 Atlantic hurricane season, which got off to an early start in May with the formation of Tropical Storms Alberto and Beryl. National Oceanic and Atmospheric Administration forecasters are calling for a near-normal hurricane season this year. But whether the season turns out to be wild or wimpy, understanding what makes these ferocious storms form and rapidly intensify is a continuing area of scientific research, and is the focus of the NASA-led Hurricane and Severe Storm Sentinel (HS3) airborne mission that kicks off this summer.

Plate tectonics cannot explain dynamics of Earth and crust formation more than three billion years ago

The current theory of continental drift provides a good model for understanding terrestrial processes through history. However, while plate tectonics is able to successfully shed light on processes up to three billion years ago, the theory isn’t sufficient in explaining the dynamics of Earth and crust formation before that point and through to the earliest formation of planet, some 4.6 billion years ago.
