Image of Mars with colors indicating the strength of the gravitational field. 1089 MOLA Surface Topography with Gravity Texture Map
One of the biggest changes to global agriculture is less about the food itself as it is about the water we use to grow it. In some areas, farmers are using freshwater resources - including groundwater - at an alarming rate. The GRACE satellites enable scientists to discover changes to underground aquifers by monitoring changes in the Earth's gravity. In northern India, farmers rely heavily on irrigation to grow crops, and the resulting massive aquifer depletion creates an uncertain future for the region. <p><p><p><p>For complete transcript, click <a href= 10512 Science for a Hungry World: Growing Water Problems
In its first year of operations, NASA’s Fermi Gamma-ray Space Telescope has mapped the entire sky with unprecedented resolution and sensitivity in gamma-rays, the highest-energy form of light. On May 10, 2009 a pair of gamma-ray photons reached Fermi only 900 milliseconds apart after traveling for 7 billion years. Fermi’s measurement gives us rare experimental evidence that space-time is smooth as Einstein predicted, and has shut the door on several approaches to gravity where space-time is foamy enough to interfere strongly with light.<p><p><p>For complete transcript, click <a href= 10510 Einstein's Cosmic Speed Limit
The primary goal of the GRACE mission is to accurately map variations in the Earth's gravity field over its 5-year lifetime. 10480 GRACE Beauty Pass Animations
