New NASA satellite mapped the oceans like never before
(zmescience.com)
The ocean floor is a vast scope on our planet that remains largely unexplored. Although oceans cover 71% of Earth, we have clearer pictures of the Moon and Mars than we do of the landscape beneath the waves. But a newly launched satellite mission coined SWOT (Surface Water and Ocean Topography) is now giving scientists a much sharper picture of these hidden underwater worlds.
