UMD, NASA to Launch GEDI to Study Forest Changes on Earth

A University of Maryland-led project, the Global Ecosystem Dynamics Investigation instrument (GEDI), is undergoing final integration and testing this spring and summer at NASA's Goddard Space Flight...
Earth’s Orbital Changes

Earth’s Orbital Changes Have Influenced Climate, Life Forms For at Least...

Every 405,000 years, gravitational tugs from Jupiter and Venus slightly elongate Earth’s orbit, an amazingly consistent pattern that has influenced our planet’s climate for...
